These and other embodiments, features, and advantages of the present disclosure will be apparent to those skilled in the art. The present disclosure is not to be limited to or by these embodiments, features, and advantages.

Referring now to the drawings, exemplary illustrations are shown in detail. Although the drawings represent schematic embodiments, the drawings are not necessarily to scale and certain features may be exaggerated to better illustrate and explain an innovative aspect of an illustrative embodiment. Further, the exemplary illustrations described herein are not intended to be exhaustive or otherwise limiting or restricting to the precise form and configuration shown in the drawings and disclosed in the following detailed description.

As medical professionals strive for reducing the size of the incisions and the amount of recovery time required following invasive medical procedures, the size of medical instruments used in various medical procedures have become smaller. Many of the medical instruments utilized in performing the various medical procedures may include the use of a cutting accessory, such as high-speed drills, rotating burs, open-window shavers, and the like. An exemplary medical instrument is disclosed in <CIT>. Many of these cutting accessories may require the use of irrigation or suction to reduce heat and/or remove debris at the surgical site. Similarly, irrigation may be utilized to lubricate a cutting accessory. Generally, an elongate member, such as those including a lumen, may be utilized to direct fluid from an irrigation source toward the surgical site and/or the cutting accessory. The elongate member may be disposable as part of the sterilization process, resulting in the elongate member only temporarily being attached to the medical instrument. The introduction of additional elements, such as the elongate member for providing irrigation, can result in increasing the size, profile, and/or general bulkiness of the medical instrument. A loose elongate member extending from the irrigation system to the cutting accessory may obstruct the medical professional's view and/or distract the medical professional during operation of the medical instrument during the medical procedure. The positioning of the elongate member relative to the medical instrument may similarly affect the ergonomics of the medical instrument, inhibiting the medical professional's ability to manipulate the medical instrument. Therefore, the medical professional may utilize an attachment device and/or assembly for securing an elongate member to a medical instrument, such as the attachment device <NUM> illustrated in <FIG>.

Referring to <FIG>, an example configuration of an attachment device <NUM> is illustrated. Accordingly, the attachment device <NUM> may comprise a base <NUM>, adhesive <NUM>, and a liner <NUM>, wherein the attachment device <NUM> is configured for attachment to a medical instrument <NUM>. The attachment device <NUM> may be configured as a laminate, wherein each of the base <NUM>, adhesive <NUM>, and liner <NUM> makeup the various layers of the attachment device <NUM> as shown in <FIG>, and may by positioned directly adjacent one another. For example, referring to <FIG>, the attachment device <NUM> comprises a base <NUM>, an adhesive <NUM>, and a liner <NUM> that have been layered on top of one another. Alternatively, the base <NUM>, adhesive <NUM>, and liner <NUM> may be configured as individual elements that may be assembled using the adhesive <NUM> to interconnect the base <NUM> and the liner <NUM>.

The base <NUM> may comprise a material that is flexible and tear-resistant. For example, the base may comprise a plastic or composite material. The base <NUM> may similarly be resistant to degradation or erosion when utilized in a medical setting, such as a hospital or operating room. For example, the base <NUM> may be cut in various shapes, such as a generally elliptical shape, as illustrated in <FIG> to define one or more apertures (18A, 18B) in a complementary shape, as described below. The generally elliptical shape may provide the necessary structural properties while also providing a limited profile when coupling the attachment device <NUM> to a medical instrument having a generally convex surface. While not shown in the figures, it is contemplated that the base <NUM> may be cut in different shapes and/or configurations based on the application. For example, the base <NUM> may be cut in a square, rectangular, or similar polygonal shape. This may provide alternative structural properties and/or advantages when coupling the attachment device <NUM> to a generally flat surface. However, the examples described above are not intended to be limiting. For example, it is contemplated that the polygonal-shaped base may be coupled to a convex surface and the generally circular-shaped base <NUM> may be coupled to a flat surface.

The base <NUM> may be at least partially translucent and treated for printing, such that text and/or graphics may be printed on a portion of the base <NUM>. For example, the base <NUM> may include printed identifying marks or graphics, as well as indicia representative of instructions for using the attachment device <NUM>. The base <NUM> may also be markable, i.e., include a writing surface, such that a medical professional may write a date of use or installation on the base <NUM> using a typical writing utensil, such as a pen, marker, or pencil.

The adhesive <NUM> may be generally disposed on at least one surface of the base <NUM> such that a portion of the adhesive <NUM> may be positioned between the base <NUM> and the liner <NUM>. For example, the adhesive <NUM> may be applied to or cover the entire area of at least one surface, such as the bottom, of the base <NUM>, and the liner <NUM> may be configured to cover a defined area of the adhesive <NUM>, leaving a portion of the adhesive disposed on the base <NUM> exposed. The exposed portion of the adhesive <NUM> (not covered by the liner <NUM>) may be configured to removably couple the attachment device <NUM> to a medical instrument <NUM> (discussed in detail below). In other words, the liner remains on the attachment device <NUM> after the attachment device is secured to the medical instrument <NUM>.

The adhesive <NUM> may comprise a chemical compound, such as a paste, silicone, glue, rubber cement, or similar adhesive substance configured to adhere the base <NUM> to the liner <NUM> and/or the medical instrument <NUM>. The adhesive <NUM> may similarly be configured as an adhesive tape, such as double-sided tape with an adhesive on both sides to allow for adhesion to both the base <NUM> and the liner <NUM>. For example, the adhesive <NUM> may be a medical grade adhesive manufactured by <NUM>™, such as <NUM>™ <NUM> Polyethylene Single Sided Medical Tape. The adhesive <NUM> may be configured such that it is suitable for use in wet and/or unclean environments and is safe for attachment to human skin.

The liner <NUM> is configured to be coupled to the adhesive, such that the liner <NUM> may be positioned adjacent, such as directly adjacent, to the adhesive <NUM> opposite the base <NUM>. The liner <NUM> may be configured to be disposed on the adhesive <NUM>, such that the liner <NUM> covers a portion or defined area of the adhesive <NUM>. The liner <NUM> may be removably coupled to the adhesive <NUM> of the attachment device <NUM>. The liner <NUM> may comprise material that has been treated with a chemical compound that allows for easy removal of the liner <NUM> from the adhesive <NUM>. For example, the liner <NUM> may comprise a wax or Teflon™ coating. The liner <NUM> may be thought of as being similar to the backing of a sticker, wherein the liner <NUM> may remain coupled to the adhesive <NUM>, but can be easily removed or separated from the adhesive <NUM>. However, at least of the portion of the liner <NUM> may remain on the attachment device when the attachment device is secured to the medical instrument.

As illustrated in <FIG>, the attachment device <NUM> may comprise a first base aperture 18A and a second base aperture 18B in the base <NUM>. While the figures illustrate a configuration of the attachment device <NUM> comprising the first base aperture 18A and the second base aperture 18B, it should be understood that it is contemplated that the attachment device <NUM> may be configured with a single base aperture, or three or more base apertures. Depending on the location, shape, and/or number of base apertures 18A, 18B, the position and configuration of the adhesive <NUM> and/or liner <NUM> may be altered, including apertures thereof, which will be discussed in detail below.

The first base aperture 18A and the second base aperture 18B may also be configured to define a longitudinal axis L, as illustrated in <FIG>. For example, the longitudinal axis L bisects the first base aperture 18A and the second base aperture 18B. In one or more of the configurations of the attachment device <NUM> described below, the liner <NUM> may be configured to be substantially aligned with the longitudinal axis L defined by the first base aperture 18A and the second base aperture 18B. In one aspect, aligned is meant to refer to a longitudinal axis of the liner <NUM> being parallel to the longitudinal axis L. More generally, in some aspects, at least a portion of the liner <NUM> is disposed on the adhesive <NUM> between the first base aperture 18A and the second base aperture 18B. In other words, in certain aspects, the liner <NUM> may be arranged in other fashions relative to the longitudinal axis L and/or the first and second base apertures 18A, 18B.

The attachment device <NUM> may also comprise an adhesive aperture 19A, 19B in the adhesive <NUM>. The adhesive aperture(s) 19A, 19B may be configured to be aligned, such as coaxial, with the first base aperture 18A and the second base aperture 18B. It is further contemplated that the liner <NUM> may also comprise a liner aperture(s) 21A, 21B, wherein the liner aperture(s) 21A, 21B may be aligned, such as coaxial, with the first base aperture 18A and the second base aperture 18B and/or the adhesive aperture(s) 19A, 19B. Thus, in one aspect, the base aperture(s) 18A, 18B, the adhesive apertures 19A, 19B, and the liner apertures 21A, 21B may be collectively arranged such that center of each aperture is aligned. However, in other aspects, the base aperture 18A, 18B, the adhesive apertures 19A, 19B, and liner apertures 21A, 21B may be partially coincident such that the elongate member can pass therethrough. The shapes and/or sizes of the base apertures 18A, 18B, adhesive apertures 19A, 19B, or liner apertures 21A, 21B may be the same or may be different. For example, as illustrated in <FIG>, the size of the base aperture(s) 18A, 18B and/or the adhesive aperture(s) 19A, 19B may be configured to be larger than the liner aperture(s) 21A, 21B in order to prevent transference of the adhesive <NUM> to an object passing through the base aperture(s) 18A, 18B.

Alternatively, in another configuration of the attachment device <NUM>, the base <NUM> and/or the may further comprise a recess <NUM>, bevel, chamfer, fillet, or similar transition between opposing surfaces of the base <NUM> surrounding the base aperture(s) 18A, 18B. The recess <NUM> surrounding the aperture(s) 18A, 18B may be configured to reduce any stresses or strain on the base <NUM> at the circumference of the aperture(s) 18A, 18B.

Referring to <FIG>, a first exemplary liner 16A configuration is illustrated. In the first exemplary configuration of the liner 16A, the liner 16A is configured such that at least a portion of the liner 16A is removably coupled to the adhesive <NUM> this disposed on the base <NUM> between the first and second base apertures 18A, 18B. The liner 16A may also be configured to extend beyond the area of the adhesive <NUM> disposed on the base <NUM> between the first and second base apertures 18A, 18B. For example, the liner 16A may be configured to also cover a portion of the adhesive <NUM> that is disposed on the base <NUM> surrounding the first and second base apertures 18A, 18B, as illustrated in <FIG>, that is not on the base between the first and second apertures 18A, 18B. In this liner 16A configuration, the liner 16A may comprise liner apertures 21A, 21B.

The sectional view illustrated in <FIG> illustrates an attachment device <NUM> wherein the base aperture(s) 18A, 18B, the adhesive aperture(s) 19A, 19B each comprise a generally uniform diameter. The liner aperture(s) 21A, 21B may be configured to be smaller relative to the size of the base aperture(s) 18A, 18B and /or the adhesive aperture(s) 19A, 19B. This may prevent the transference of the adhesive <NUM> to an object passing through the base aperture(s) 18A, 18B. While not shown in the figures, it is contemplated that the size of the liner aperture(s) 21A, 21B of the attachment device <NUM> may be may be the same size as the base aperture(s) 18A, 18B and /or the adhesive aperture(s) 19A, 19B. For example, the base aperture(s) 18A, 18B, the adhesive aperture(s) 19A, 19B and/or liner aperture(s) 21A, 21B may be configured to comprise a uniform size, such as diameter, through the attachment device <NUM>. It is also contemplated that the first base 18A, first liner 19A, and first adhesive 21A apertures may be sized and/or shaped differently than the second base 18B, second liner 19B, and second adhesive 21B apertures.

The base aperture(s) 18A, 18B, the adhesive aperture(s) 19A, 19B, and the liner aperture(s) 21A, 21B may be generally aligned, such coaxial, when the base <NUM>, adhesive <NUM>, and/or liner <NUM> are layered or stacked on top of one another, such that the base aperture(s) 18A, 18B, the adhesive aperture(s) 19A, 19B, and the liner aperture(s) 21A, 21B form a continuous aperture through the attachment device <NUM>. Alternatively, it is also contemplated that the size, shape, and/or position of each aperture may be different. For example, the center of the base aperture(s) 18A, 18B and/or the adhesive aperture(s) 19A, 19B may be offset from the center of the liner aperture(s) 21A, 21B. In yet another configuration, the shape of the base aperture(s) 18A, 18B and/or the adhesive aperture(s) 19A, 19B may be different from the shape of the liner aperture(s) 21A, 21B. For example, the liner aperture(s) 21A, 21B may be configured as a circle and the base aperture(s) 18A, 18B and/or the adhesive aperture(s) 19A, 19B may be configured as an ellipse. This configuration may assist with preventing transfer of the adhesive <NUM> to the elongate member <NUM>.

In another configuration, a portion of the adhesive <NUM> may be removed from the area of the base <NUM> that surrounds the base aperture(s) 18A, 18B, increasing the size, such as the diameter, of the adhesive aperture(s) 19A, 19B. In other words, a portion of the base <NUM> surrounding the base aperture(s) 18A, 18B is not in direct contact with the adhesive <NUM>. A potential advantage of increasing the size, shape, and/or position of the base aperture 18A, 18B and/or adhesive aperture(s) 19A, 19B relative to the liner aperture(s) 21A, 21B is to prevent oozing or transference of the adhesive <NUM> onto the elongate member <NUM> when threaded through the base apertures 18A, 18B of the attachment device <NUM>.

Referring to <FIG>, a second exemplary liner 16B configuration is illustrated. In the second exemplary configuration of the liner 16B, the liner 16B is configured such that at least a portion of the liner 16B is coupled to the adhesive <NUM> that is disposed on the base between the first and second base apertures 18A, 18B. In the second configuration of the liner 16B, the portion of the liner 16B that is coupled to the adhesive <NUM> may not surround the first and second base apertures 18A, 18B and/or the adhesive aperture(s) 19A, 19B. The liner 16B, as illustrated in <FIG>, is configured as a strip, belt, strap, band, or ribbon of material coupled to a portion of the adhesive <NUM> that is disposed on the base <NUM> between the first and second base apertures 18A, 18B.

The length and width of the liner 16B may be configured based on the size of the base aperture(s) 18A, 18B, and/or the adhesive aperture(s) 19A, 19B, as well as the dimensions of the elongate member <NUM>. The length and width of the liner 16B may also be configured based on the distance between the base aperture(s) 18A, 18B, and/or the adhesive aperture(s) 19A, 19B. While not required, the width of the liner 16B may typically be at least as large as the size of the base aperture(s) 18A, 18B, and/or the adhesive aperture(s) 19A, 19B. For example, the width of the liner 16B may the same or larger that the diameter of the base aperture(s) 18A, 18B and/or the adhesive aperture(s) 19A, 19B. The length of the liner 16B may also be dependent on the size of the adhesive aperture(s) 19A, 19B. For example, in order to prevent a portion of the adhesive <NUM> disposed on the base <NUM> that covers the area between the base aperture(s) 18A, 18B from being exposed, the edges of the liner 16B, the liner 16B may be configured to cover at least the portion of adhesive <NUM> disposed on the base <NUM> between the base aperture(s) 18A, 18B. As illustrated in <FIG>, the length of the liner 16B may be longer the distance between the edges of the base aperture(s) 18A, 18B and/or the adhesive aperture(s) 19A, 19B, such the liner 16B extends into and coves a portion of the base aperture(s) 18A, 18B and/or the adhesive aperture(s) 19A, 19B. Alternatively, if the adhesive <NUM> is flush with the base aperture(s) 18A, 18B, then the liner 16B may be similarly configured to extend between the edges of the base aperture(s) 18A, 18B, such that the liner 16B is also flush with the edge(s) of the base aperture(s) 18A, 18B. However, if a portion of the adhesive <NUM> is removed surrounding the base aperture(s) 18A, 18B, the length of the liner 16B may be shortened, such that the liner 16B will only cover the area on the base <NUM> that is between the base aperture(s) 18A, 18B that is in contact with the adhesive <NUM>.

Referring to <FIG>, a third exemplary liner 16C configuration is illustrated. Similar to the liner 16A, 16B configurations illustrated in <FIG>, the third exemplary configuration of the liner 16C may be coupled to the adhesive <NUM> and may be positioned adjacent the base aperture(s) 18A, 18B. The liner 16C may be couple to a portion of the adhesive <NUM> such that the liner 16C is substantially parallel, or collinear, with a longitudinal axis L that may bisect the first base aperture 18A and the second base aperture 18B. The liner 16C may be configured to be substantially aligned with the longitudinal axis L defined by the first base aperture 18A and the second base aperture 18B, wherein aligned is meant to refer to a longitudinal axis of the liner <NUM> being parallel to the longitudinal axis L. As illustrated in <FIG>, it is not required that the liner 16C be disposed on a portion of the adhesive <NUM> between the first and second base apertures 18A, 18B. In the example configuration illustrated in <FIG>, the liner 16C may comprise multiple pieces disconnected from one another and positioned adjacent to the base aperture(s) 18A, 18B, wherein the pieces of the liner 16C veer out from the base aperture(s) 18A, 18B relative to the center of the attachment device <NUM>. Alternatively, the liner 16C may be disposed on a portion of the adhesive <NUM> that is disposed on the base <NUM> that is not between the first and second base apertures 18A, 18B, but is adjacent to the first and/or second base apertures 18A, 18B.

The size and/or position of the liner 16C may be based, at least in part, on the size and/or position of the base aperture(s) 18A, 18B and/or the adhesive aperture(s) 19A, 19B, as well as the dimensions of the elongate member <NUM>. The length and width of the liner 16C may also be configured based on the distance between the base aperture(s) 18A, 18B, and/or the adhesive aperture(s) 19A, 19B, and the outer edge of the attachment device <NUM>. While not required, the width of the liner 16C may typically be at least as large as the size of the base aperture(s) 18A, 18B, and/or the adhesive aperture(s) 19A, 19B. For example, the width of the liner 16C may the same or larger that the diameter of the base aperture(s) 18A, 18B and/or the adhesive aperture(s) 19A, 19B. The length of the liner 16C may also be dependent on the size of the adhesive aperture(s) 19A, 19B. For example, in order to prevent a portion of the adhesive <NUM> disposed on the base <NUM> that covers the area between the base aperture(s) 18A, 18B and the outer edge(s) of the attachment device <NUM> from being exposed, the edges of the liner 16C, the liner 16C may be configured to cover at least the portion of adhesive <NUM> disposed on the base <NUM> between the base aperture(s) 18A, 18B and the outer edge(s) of the attachment device <NUM>. As illustrated in <FIG>, the length of the liner 16C may be longer the distance between the edges of the base aperture(s) 18A, 18B and the outer edges of the attachment device <NUM>, such the liner 16C extends into and coves a portion of the base aperture(s) 18A, 18B and/or the adhesive aperture(s) 19A, 19B. Alternatively, if the adhesive <NUM> is flush with the base aperture(s) 18A, 18B, then the liner 16C may be similarly configured to extend between the edges of the base aperture(s) 18A, 18B, such that the liner 16C is also flush with the edge(s) of the base aperture(s) 18A, 18B. However, if a portion of the adhesive <NUM> is removed surrounding the base aperture(s) 18A, 18B, the length of the liner 16C may be shortened, such that the liner 16C will only cover the area on the base <NUM> that is between the base aperture(s) 18A, 18B and the outer edge(s) of the attachment device <NUM> that is in contact with the adhesive <NUM>.

While various configurations of the liner <NUM> have been discussed above, it should be understood that it is also contemplated that the attachment device <NUM> may be configured without a liner. In an embodiment of the attachment device <NUM>, that does not include the liner, a portion of the adhesive that corresponds to the same general location, position, and/or shape that the liner may be removed from the attachment device <NUM>. For example, the attachment device <NUM> may be configured to comprise a base <NUM> including a top surface and a bottom surface. As described above, the attachment device <NUM> may similarly comprises the first base aperture 18A, and the second base aperture 18B. The adhesive <NUM> may be at least partially disposed on the bottom surface of the base <NUM>, such that the area of the base <NUM> base <NUM> between the first base aperture 18A and the second base aperture 18B is free from adhesive. The attachment device <NUM> may be configured wherein the area of the base <NUM> that is free from adhesive may correspond to the areas described above where the adhesive is covered by the liner.

Referring to <FIG>, an exemplary configuration of an attachment device assembly <NUM> is illustrated. The attachment device assembly <NUM> may comprise the attachment device <NUM> described above and an indicator tab <NUM>. The indicator tab <NUM> may comprise a second liner <NUM> configured to removably couple to the adhesive <NUM> of the attachment device <NUM> that is not covered by the liner <NUM>. The second liner <NUM> and the liner <NUM> may comprise similar or the same materials. The liner <NUM> and second liner <NUM> may even be integrally formed from a single piece of material, wherein the material is cut to create the liner <NUM> and second liner <NUM>. The liner <NUM> and second liner <NUM> may be cut such that the liner <NUM> is configured to remain coupled to the adhesive <NUM> of the attachment device <NUM> when the attachment device <NUM> is removed and/or separated from the indicator tab <NUM>. For example, as illustrated in <FIG>, the second liner <NUM> comprises a second liner aperture <NUM> corresponding to the shape of the liner <NUM> that remains coupled to the attachment device <NUM>. When the second liner <NUM> is removed by separating the indicator tab <NUM> from the attachment device <NUM>, a portion of the adhesive <NUM> that is disposed on the base <NUM> of the attachment device <NUM> corresponding to the second liner <NUM> is exposed. The exposed portion of the adhesive <NUM> may be configured to secure the attachment device <NUM> to another object, such as a medical instrument <NUM>.

The second liner <NUM> may be integrally formed with the indicator tab <NUM> of the attachment device assembly <NUM>. However, while not illustrated in the figures, it is contemplated that the second liner <NUM> may be configured as an element of the indicator tab <NUM>. For example, the indicator tab <NUM> may be constructed of a laminate material or layers similar to the attachment device <NUM> described above. In this example configuration, the indicator tab <NUM> may comprise a base indicator layer, an adhesive indicator layer, and the second liner, wherein the second liner is removably coupled to the adhesive indicator layer.

The indicator tab <NUM> of the attachment device assembly <NUM> may further comprise an indicia portion <NUM>. The indicia portion <NUM>, similar to the base <NUM> of the attachment device <NUM>, may be translucent and treated for printing, such that text and/or graphics may be printed on the indicia portion <NUM>. For example, the indicia portion <NUM> may include printed identifying marks, illustrations, text, or graphics that are representative of instructions for using the attachment device <NUM>. The indicia portion <NUM> may also be markable, such that a medical professional may write a date of use or installation on the indicia portion <NUM> using a typical writing utensil, such as a pen, marker, or pencil. Referring to <FIG>, an example illustration of the indicia portion <NUM> of the indicator tab <NUM> is shown.

Illustrated in <FIG> and <FIG> is an exemplary configuration of an irrigation assembly <NUM>, including an elongate member <NUM> threaded through the attachment device assembly <NUM> described above. The elongate member <NUM> may be constructed from a plastic, a polymer, or similar durable and flexible material. The elongate member <NUM> may also comprise a lumen configured to create a canal, duct, or passageway that allows for the flow of a fluid. For example, the elongate member may be used to provide fluid to the surgical site, or suction debris away from the surgical site through the elongate member <NUM>. The elongate member <NUM> may be configured for a navigation tracker of a navigation system, or a control console.

The elongate member may further comprise a distal end <NUM> and a proximal end <NUM>. The proximal end <NUM> may be configured to couple to a surgical system, such as an irrigation system (not illustrated in the figures). The proximal end <NUM> may comprise a proximal coupler <NUM>, wherein the proximal coupler <NUM> may be configured to couple the proximal end <NUM> to the surgical system. The proximal coupler <NUM> may comprise a barbed connector, a luer connector, electrical connector, or similar fitting. It will be appreciated that the proximal coupler <NUM> may be coupled to the proximal end <NUM> of the elongate member <NUM> in a number of different ways, such as via ultraviolet bonding, gluing, cement, epoxy, plastic weld, and the like. It should also be appreciated that the proximal coupler <NUM> may be omitted, and the elongate member <NUM> may be coupled directly to the surgical system.

The distal end <NUM> may be configured to couple to a medical instrument accessory <NUM>, such as an irrigation sleeve. An exemplary irrigation sleeve for use with a medical instrument is disclosed in <CIT>. The distal end <NUM> of the elongate member may comprise a barbed connector, a luer connector, or similar fitting configured to couple the elongate member <NUM> to the medical instrument accessory <NUM>. Alternatively, the medical instrument accessory <NUM> may comprise an accessory coupler <NUM> configured to receive the distal end <NUM> of the elongate member <NUM>. The accessory coupler <NUM> may be coupled to the distal end <NUM> of the elongate member <NUM> in a number of different ways, such as via ultraviolet bonding, gluing, cement, epoxy, plastic weld, and the like. It should also be appreciated that the accessory coupler <NUM> may be omitted, and the elongate member <NUM> may be configured to be positioned proximate to the medical instrument accessory <NUM> and apply fluid directly to the surgical sight.

As described above, the attachment device <NUM> may comprise a number of base apertures 18A, 18B. The base aperture(s) 18A, 18B may be configured to receive the elongate member <NUM>, which may be threaded through the base aperture(s) 18A, 18B in the attachment device <NUM>. The dimensions and/or thickness of the base aperture(s) 18A, 18B may be configured to reduce any stresses or strain on the base <NUM> and/or elongate member <NUM> when the elongate member <NUM> is threaded through the base aperture(s) 18A, 18B. The diameter of the base aperture(s) 18A, 18B and/or distance between the base aperture(s) 18A, 18B may be configured to create a friction fit for the elongate member <NUM> when threaded through the base aperture(s) 18A, 18B. This will hold the elongate member <NUM> in place, unless an additional force is applied to the elongate member <NUM>, such as the medical professional pulling the elongate member <NUM> in one direction or the other. Alternatively, as discussed above, the base may also comprise a recess <NUM>, wherein the dimensions and/or thickness of the recess <NUM> surrounding the base aperture(s) 18A, 18B may be configured to reduce any stresses or strain on the base <NUM> and/or elongate member <NUM> when the elongate member <NUM> is threaded through the base aperture(s) 18A, 18B.

As discussed above, there are a number of different liner 16A, 16B, and 16C configurations that may be utilized. However, the liner 16A, 16B, and 16C configuration may dictate the direction and orientation with which the elongate member <NUM> is threaded through the base aperture(s) 18A, 18B of the attachment device <NUM>. Referring to <FIG> and <FIG>, the threading configuration of the elongate member <NUM> with relation to the attachment device <NUM> would correspond to the liner 16A, 16B illustrated in <FIG>, wherein the liner 16A, 16B is positioned adjacent the adhesive <NUM> and at least partially between the base aperture(s) 18A, 18B. The elongate member <NUM> is threaded through the base aperture(s) 18A, 18B of the attachment device <NUM> such that an intermediary portion of the elongate member <NUM> that is positioned between the base aperture(s) 18A, 18B is adjacent to the liner 16A, 16B. <FIG> shows the elongate member <NUM> positioned adjacent to the liner <NUM> as it extends between the base aperture(s) 18A, 18B. One of the many functions of the liner <NUM> is to prevent the elongate member <NUM> from being coupled to the adhesive <NUM>, thus allowing the elongate member <NUM> to be slid axially when attached to the medical instrument <NUM>.

Alternatively, the threading configuration of the elongate member <NUM> may be configured to correspond to the liner 16C illustrated in <FIG>. This would be the inverse of the elongate member <NUM> threading illustrated in <FIG> and <FIG>. In the liner 16C configuration illustrated in <FIG>, the liner 16C comprises two separate pieces that are placed adjacent to the base aperture(s) 18A, 18B. However, in this configuration, the liner 16C may not be positioned between the base aperture(s) 18A, 18B. In threading the elongate member <NUM> through the base aperture(s) 18A, 18B, the elongate member <NUM> is threaded through the base aperture(s) 18A, 18B of the attachment device <NUM> such that an intermediary portion of the elongate member <NUM> that is positioned between the base aperture(s) 18A, 18B is adjacent to the base <NUM>, i.e., on the top of the attachment device <NUM>. The opposing ends of the elongate member <NUM> are positioned adjacent to the pieces of the liner 16C.

While not illustrated in the figures, it should be appreciated that additional base aperture(s) 18A, 18B and/or liner configurations are contemplated to allow for additional threading configurations. Irrespective of the number of base aperture(s) 18A, 18B and/or pieces of liner <NUM>, it should be appreciated that when threading the elongate member <NUM> through the base aperture(s) 18A, 18B, a piece of liner <NUM> will typically be included between the adhesive <NUM> and the elongate member <NUM> to prevent exposure of the elongate member <NUM> to the adhesive <NUM>.

Alternatively, instead of including a liner <NUM> as an element of the attachment device <NUM>, it is further contemplated that the adhesive <NUM> that corresponds with the location of the liner <NUM> may be removed from the base <NUM> (referring to the liner 16A, 16B, and 16C illustrated in <FIG>). By removing portions of the adhesive <NUM> that correspond with the location of the liner 16A, 16B, and 16C illustrated in the figures, the liner 16A, 16B, and 16C may be unnecessary, and therefore, the liner 16A, 16B, and 16C may be omitted from the attachment device <NUM>.

Referring to <FIG>, an exemplary configuration of a surgical system <NUM> is illustrated. The surgical system <NUM> may be configured to comprise a medical instrument <NUM> and the irrigation assembly <NUM> described above. The medical instrument <NUM> may comprise a medical instrument accessory <NUM>, such as a cutting accessory or irrigation sleeve. The elongate member <NUM> of the irrigation assembly <NUM> may be threaded through the base aperture(s) 18A, 18B of the attachment device <NUM>, and the distal end <NUM> coupled to the medical instrument accessory <NUM>.

Referring to <FIG>, the attachment device <NUM> may be removed from the indicator tab <NUM>, exposing a portion or area of the adhesive <NUM> that is not covered by the liner <NUM>. The attachment device <NUM> may then be removably coupled to the medical instrument <NUM> via the exposed portion of the adhesive <NUM>. The attachment device <NUM> may be coupled to the medical instrument <NUM> at any point along the body <NUM> of the medical instrument <NUM>, as illustrated in <FIG>. For example, the attachment device <NUM> may be coupled to the body <NUM> of the medical instrument <NUM> proximate to the medical instrument accessory <NUM>. Alternatively, the attachment device <NUM> may be coupled to the body <NUM> of the medical instrument <NUM> distal to the medical instrument accessory <NUM>. The medical professional may select the location to couple the attachment device <NUM> to the medical instrument <NUM>. For example, the medical professional may consider the size of elongate member, type of medical procedure to be performed, ergonomic grip of the medical instrument <NUM>, or the like, when selecting the location to couple the attachment device <NUM> to the medical instrument <NUM>.

As illustrated in <FIG>, the elongate member <NUM> is threaded through the base aperture(s) 18A, 18B of the attachment device <NUM> such that the elongate member <NUM> is axially aligned with the liner 16A when attached to the body <NUM> of the medical instrument. A portion of the elongate member <NUM> is positioned between the liner 16A and the body <NUM> of the medical instrument <NUM> when the attachment device <NUM> is coupled to the medical instrument <NUM>. The presence of the liner 16A between the adhesive <NUM> and the elongate member <NUM> allows for the elongate member <NUM> to be axially slid while attached to the medical instrument <NUM>. This allows for the medical professional to easily adjust the elongate member <NUM> to be taut, or provide additional slack in the elongate member <NUM> when needed.

Furthermore, <FIG> illustrate various steps of an exemplary method of attaching the elongate member <NUM> to the medical instrument <NUM> using the attachment device <NUM>. The method of attaching the elongate member <NUM> to the medical device may comprise providing the attachment device <NUM> and or assembly <NUM>, wherein the attachment device <NUM> comprises the liner <NUM>, the base <NUM>, and the adhesive <NUM> disposed at least partially between the base <NUM> and the liner <NUM>. The attachment device <NUM> may further comprise the first base aperture 18A and the second base aperture 18B. The liner <NUM> may be positioned adjacent to the adhesive <NUM>, such that the liner <NUM> is at least partially between the first base aperture 18A and the second base aperture 18B and adjacent to the adhesive. The method may further comprise threading the elongate member <NUM> through the first base aperture 18A and the second base aperture 18B of the attachment device <NUM>, such that the elongate member <NUM> is axially aligned with the liner <NUM>. Alternatively, as described above with reference to the liner 16C configuration illustrated in <FIG>, the liner 16C may be positioned proximate to the base aperture(s) 18A, 18B and positioned adjacent to the adhesive <NUM>. The liner 16C may be aligned with the longitudinal axis defined by the base apertures 18A, 18B.

The method of securing the elongate member <NUM> may further comprise adhering the attachment device <NUM> to the medical instrument <NUM>. The attachment device <NUM> may be removably coupled to the body <NUM> of the medical instrument <NUM> by pressing the exposed portion of the adhesive <NUM> to the body <NUM> of the medical instrument <NUM>, such that the elongate member <NUM> is at least partially disposed between the attachment device <NUM> and the medical instrument <NUM>. For example, the attachment device <NUM> including the elongate member <NUM> threaded through the aperture(s) 18A, 18B may be pressed against the base <NUM> to secure the attachment device <NUM> to the medical instrument <NUM>.

The method may further comprise separating the indicator tab <NUM> of the attachment device assembly <NUM> described above from the adhesive <NUM>. The indicator tab <NUM> may be separated or removed by pulling on the elongate member <NUM> that is threaded through the attachment device <NUM> of the assembly <NUM>. The indicator tab <NUM> may be configured to comprise indicia <NUM> representative of the method of coupling the attachment device <NUM> to the medical instrument <NUM>.

The method may further comprise axially sliding the elongate member <NUM> adjacent to the liner <NUM> such that the elongate member <NUM> is taut when the attachment device <NUM> is coupled to the medical instrument <NUM>. For example, pulling on the proximal end <NUM> of the elongate member <NUM> to remove any slack in the distal end <NUM> of the elongate member <NUM>. This may reduce the profile and or bulkiness of the surgical system <NUM>. It may also prevent the elongate member <NUM> from becoming caught on or entangled with something during operation of the medical instrument <NUM>. Alternatively, the elongate member <NUM> may be slid by pulling on the distal end <NUM> to create additional slack in the elongate member <NUM>.

The method may also comprise removing the second liner <NUM> from the adhesive <NUM>, wherein removal of the second liner <NUM> exposes the portion of the adhesive <NUM> configured to removably couple the attachment device <NUM> to the medical instrument <NUM>.

After adhering the attachment device <NUM> to the medical instrument <NUM>, the method may comprise separating the attachment device <NUM> from the medical instrument <NUM> by pulling on the elongate member <NUM>. For example, pulling on the proximal end <NUM> of the elongate member <NUM> may remove and/or detach the attachment device <NUM> from the medical instrument <NUM>. Allowing the elongate member and attachment device <NUM> to be disposed of following a medical procedure as part of the sterilization process.

A method of manufacturing the attachment device <NUM> and/or assembly <NUM> that is described above may comprise providing a base <NUM> having a top surface and an opposing bottom surface. One or more base aperture(s) 18A, 18B may be cut in the base <NUM>. For example, a die cutting process may be utilized to cut the first base apertures 18A and the second base aperture 18B. The adhesive <NUM> may be applied to the bottom surface of the base <NUM>. The adhesive <NUM> may be applied to the base <NUM> such that the adhesive <NUM> is flush to the first base aperture18A and the second base aperture 18B. Alternatively, the adhesive <NUM> may be applied to the base <NUM> such that a portion of the base <NUM> surrounding the first base aperture 18A and the second base aperture 18B is free from the adhesive <NUM>.

The method may further comprise removably coupling the liner 16A, 16B, 16C to the adhesive <NUM>, such that the liner 16A, 16B is at least partially disposed between the first base aperture 18A and the second base aperture 18B in the base <NUM>. Alternatively, as described above, the liner 16C may be configured such that it is not positioned between the first base aperture 18A and the second base aperture 18B.

The method may also comprise cutting a recess <NUM>, bevel, chamfer, fillet, or similar transition in the top surface of the base <NUM> configured to surround each of the first base aperture 18A and the second base aperture 18B. The recess <NUM> may be created by making a secondary cut in any number of shapes, such as a circular cut. The shape of the recess <NUM> created by the secondary cut may correspond to the shape of the first base aperture 18A and the second base aperture 18B. Alternatively, the shape of the recess <NUM> may be different from the shape of the first base aperture 18A and the second base aperture 18B. Generally, the size and/or dimensions of the recess <NUM> created by the secondary cut may be larger than the size and/or dimensions of the first base aperture 18A and the second base aperture 18B. For example, wherein the secondary cut is a circular cut, the secondary cut may be centered at the midpoint of the first base aperture 18A and the second base aperture 18B, wherein the diameter of the secondary cut to create the recess <NUM> is larger than the diameter of the first base aperture 18A and the second base aperture 18B. The secondary cut configured to create the recess may also be referred to as a "kiss-cut" or a relief cut.

It is further contemplated that the attachment device <NUM> may be manufactured by starting pre-assembled piece of material that may include the base <NUM>, the adhesive <NUM> applied to one surface of the base <NUM>, and the liner 16A, 16B, 16C removably coupled to the adhesive <NUM>. In this configuration, the method of manufacturing the attachment device <NUM> may comprise cutting one or more base aperture(s) 18A, 18B through the base <NUM>, the adhesive <NUM>, and the liner16A, 16B, 16C. The method may further comprise cutting the liner 16A, 16B, 16C such that the liner 16A, 16B is at least partially disposed between the first base aperture 18A and the second base aperture 18B in the base <NUM>. Alternatively, as described above, the liner 16A, 16B, 16C may be cut such that the liner 16C it is not positioned between the first base aperture 18A and the second base aperture 18B. The method may also comprise cutting a recess <NUM>, bevel, chamfer, fillet, or similar transition in the top surface of the base <NUM> configured to surround each of the first base aperture 18A and the second base aperture 18B. The recess <NUM> may be created by making a secondary cut in any number of shapes, such as a circular cut. Similar to as described above, the size and/or dimensions of the recess <NUM> created by the secondary cut may be larger than the size and/or dimensions of the first base aperture 18A and the second base aperture 18B. The secondary cut configured to create the recess may also be referred to as a "kiss-cut" or a relief cut.

The method may further comprise threading the elongate member <NUM> through the first base aperture 18A and the second base aperture 18B. Utilizing the liner 16A, 16B configuration illustrated in <FIG>, the elongate member <NUM> may be threaded with the attachment device <NUM> by starting the elongate member <NUM> adjacent to the top surface of the base <NUM>, inserting the elongate member <NUM> through the first base aperture 18A, extending the elongate member <NUM> along the liner 16A, 16B, and inserting the elongate member <NUM> through the second base aperture 18B. Alternatively, utilizing the liner 16C configuration illustrated in <FIG>, the elongate member <NUM> may be threaded with the attachment device <NUM> by starting the elongate member <NUM> adjacent to the liner 16C, inserting the elongate member <NUM> through the first base aperture 18A, extending the elongate member <NUM> along the top surface of the base <NUM>, and inserting the elongate member through the second base aperture 18B.

The method may also comprise removably coupling an indicator tab <NUM> to the adhesive <NUM> proximate to the liner <NUM>, wherein the indicator tab <NUM> may be configured to comprise indicia <NUM> representative of said method of coupling the attachment device to the medical instrument. The indicia <NUM> may include text, graphics, and/or images representing the method of coupling the elongate member <NUM> to the medical instrument. The indicia <NUM> may be printed on the indicator tab <NUM> as part of the method of manufacturing the attachment device <NUM> and/or assembly <NUM>. For example, referring back to <FIG>, an example of the indicia <NUM> that may be printed on the indicator tab <NUM> is illustrated. The indicia <NUM> include graphics and/or numerals indicating the steps of attaching the elongate member <NUM> to the cutting accessory, securing the elongate member <NUM> to the medical instrument <NUM> using the attachment device <NUM>, and connecting the elongate member <NUM> to the medical system, such as an irrigation system.

As described above, the liner <NUM> may comprise a second liner <NUM>, wherein the second liner <NUM> is integrally formed with the indicator tab <NUM>. In manufacturing the attachment device assembly <NUM>, the liner <NUM> and second liner <NUM> may initially comprise a single integral piece of liner <NUM>, <NUM>. However, as the liner <NUM> is configured to remain coupled to the adhesive <NUM> when the indicator tab <NUM> is removed, it may be necessary to cut the liner <NUM>, <NUM> to allow for easy separation of the liner <NUM> and second liner <NUM> when the attachment device <NUM> is removed from the indicator tab <NUM>. Therefore, the method of manufacturing the attachment device <NUM> may further comprise cutting the liner <NUM>, <NUM> such that the second liner <NUM> may be configured to be separable from the liner <NUM>, and wherein the liner <NUM> remains at least partially disposed between the first base aperture 18A and the second base aperture 18B.

The method may also comprise cutting the liner aperture(s) 21A, 21B in the liner 16A, wherein the liner aperture(s) 21A, 21B is aligned with the base aperture(s) 18A, 18B. The base aperture(s) 18A, 18B may be defined by a first diameter, and the liner aperture(s) 21A may be defined by a second diameter. The attachment device <NUM> may be configured such that the first and second diameter are equal. However, it is also contemplated that the second diameter may be larger than the first diameter, and/or the first diameter may be larger than the second diameter.
