Devices, systems, and methods for containing internal body parts during insertion into the body
Devices for containing exposed internal body parts during insertion into the body of a human or veterinary patient are provided. The devices include a surgical pouch for containing the exposed internal body parts. The devices also include one or more sealing elements disposed on the surgical pouch between the proximal end and the distal end of the surgical pouch such that a section of the pouch is closed off when each sealing element is sealed. Also provided are methods for containing exposed internal body parts of a human or veterinary patient during insertion into the body of the patient.
This application claims the benefit of priority under 35 U.S.C. § 119(e) to U.S. Provisional Application No. 61/442,139 filed Feb. 11, 2011, the disclosure of which is incorporated by reference herein in its entirety.
Physicians may be presented with a human or veterinary patient that has exposed internal body parts protruding outside the body. These internal body parts must be put back in the patient during treatment. One example situation where this occurs is with Gastrochisis. Gastroschisis (also called paraomphalocele, laparoschisis, abdominoschisis, or abdominal hernia) is a type of inherited congenital abdominal wall defect in which the intestines and sometimes other organs develop outside the fetal abdomen through an opening in the abdominal wall near the site of the umbilicus. In Gastroschisis, the abdominal wall does not close properly and the stomach, small bowel, and/or large intestine may have come through the small opening near the umbilical cord. Within the womb, these internal body parts are floating free within the amniotic fluid and may not typically present any harm to the baby; however, once born, the baby will require immediate attention.
Surgical pouches, such as sterile plastic or silicone bags, often referred to as “silo” bags, are placed around the exposed internal body parts and used to contain the exposed internal body parts so that they may be shielded from trauma, infection, and dehydration until the body parts are put back within the body. Often the exposed internal body parts may be swollen and inflamed and require time before the swelling and inflammation subside to permit the internal body parts to be safely put back within the body. Insertion of the exposed internal body parts often takes about a week to occur.
For example, the surgical pouch may be suspended above the abdomen during the insertion process. Insertion may include assistance from gravity and/or assistance from the physician (e.g., the physician gently pushes part of the internal body parts back into the body opening). For example, as the swelling goes down and the abdomen has become used to the presence of more internal body parts, portions of the exposed internal body parts may be inserted within the body.
Devices for containing exposed internal body parts during insertion into the body are provided. The devices include a surgical pouch for containing the exposed internal body parts. The devices also include one or more sealing elements disposed on the surgical pouch between the proximal end and the distal end of the surgical pouch such that a section of the pouch is closed off when each sealing element is sealed. Also provided are methods for containing exposed internal body parts of a human or veterinary patient during insertion into the body of the patient.

Aspects of the present disclosure include devices for containing exposed internal body parts during insertion into the body of a human or veterinary patient. The devices include a surgical pouch for containing the exposed internal body parts. The devices also include one or more sealing elements disposed on the surgical pouch between the proximal end and the distal end of the surgical pouch such that the internal volume of the pouch is decreased when the sealing element is sealed.
The surgical pouch includes a distal end and a proximal end. The term “proximal end”, as used herein, refers to the end of the device, surgical pouch, component or member thereof, etc., that is nearest to the patient during use. The term “distal end”, as used herein, refers to the end of the device, surgical pouch, component or member thereof, etc., that is farthest from the patient during use. For example, the distal end of the pouch is the end of the pouch that is closest to the distal end of the device. Likewise, the proximal end of the pouch is the end of the pouch that is the closest to the proximal end of the device. The term “longitudinal axis” is also used herein to refer to the axis that extends between the proximal end and distal end of the device. It should be appreciated that the distal end of a component of the device is the end of the component that is closest to the distal end of the device.
The surgical pouch includes a sealing element disposed on the surgical pouch. The sealing element is disposed on the pouch between the distal end and the proximal end of the surgical pouch. The proximal end of the surgical pouch may include, for example, an opening to the pouch. The exposed internal body parts protrude out of the opening in the body (e.g., abdomen) of the patient and may enter the surgical pouch through the opening of the pouch.
When the sealing element is sealed, an empty section of the pouch that does not contain exposed internal body parts is closed off. In some embodiments, more than one sealing element is disposed on the pouch at different locations along the longitudinal axis of the pouch. Each sealing element enables an empty section of the pouch to be closed off from a section of the pouch that contains the exposed internal body parts. Therefore, as more and more of the exposed internal body parts is inserted into the body of the patient, thus taking up less space in the pouch, more and more empty sections of the pouch may be closed off.
When the sealing element is sealed, the internal volume of the section of the pouch containing the body parts is decreased. Each sealing element may be sealed to provide a different internal volume within the pouch. The sealing elements closer to the proximal end provide for a smaller internal volume for that section of the pouch than the sealing elements closer to the distal end of the pouch. Thus, the volume of the section of the surgical pouch containing the body parts is reduced in steps as each sealing element is sealed from the distal end to the proximal end of the pouch.
While any number of sealing elements may be implemented, example numbers of sealing elements may range from, for example, one to fifteen sealing elements, such as two to ten sealing elements, including four to seven sealing elements. The rate at which the internal body parts are displaced into the abdomen may vary. Typical rates in which the internal body parts are displaced when pushed down may be about 1-2 cm per day, for example, with five to seven days to displace the internal body parts all the way into the abdomen. The device may include a single sealing element that can be sealed after each day, for instance. This may require, for example, five or six reductions. The sealing elements may in some cases be spaced approximately 1.5 cm to 2 cm apart. It should be appreciated that the spacing may vary above 2 cm or below 1.5 cm in other embodiments. Furthermore, it should be appreciated that the displacement rate provided is exemplary and that displacement rates may vary under different circumstances.
Any variety of sealing elements may be implemented. For instance, the sealing element may comprise a pair of elements that can be mated together and stay connected so as to close off the corresponding portion of the pouch. Example sealing elements may include fasteners, such as interlocking fasteners (e.g., interlocking fasteners by Ziploc®) with or without a sliding clasp; elements that snap-fit together; elements having hook and loop design; etc. In some embodiments, the one or more sealing elements are interlocking fasteners. It should be appreciated that the same type of sealing element for multiple sealing elements on the same pouch is not necessarily required, and that in other instances, different types of sealing elements may be implemented on the same surgical pouch.
In some embodiments, the sealing element provides an airtight seal that prevents air from passing when the sealing element is sealed. For example, the surgical pouch may include an interlocking fastener that does not permit air to pass when sealed. It should be appreciated that in other embodiments, the sealing element does not necessarily provide an airtight seal that prevents air from passing, but rather generally closes off the empty section of the surgical pouch to enable the pouch to fit closer around the exposed internal body parts than the original entire volume of the surgical pouch.
In some embodiments, the surgical pouch includes a securing element disposed on the surgical pouch near the opening of the surgical pouch. The securing element secures the surgical pouch to the patient. For example, the securing element may be disposed around the opening of the surgical pouch and capable of collapsing for insertion into the opening of the body of the patient and capable of returning to an uncollapsed state once inserted into the opening. For instance, the securing element may be made from a spring or other resilient material or structure. As another example, the securing element may be adhesive disposed around the opening of the surgical pouch to secure the opening around the opening in the body of the patient.
The opening may vary in shape—e.g., circular, elliptical, square, polygonal, or other regular or irregular shape. The securing element may also vary in shape—e.g., circular, elliptical, square, polygonal, or other regular or irregular shape. In some embodiments, the opening is circular and the securing element is a ring positioned around the perimeter of the pouch opening. The ring may be collapsible, for instance, and inserted into the opening while it is collapsed. The ring may also be resilient, for instance, and return to an uncollapsed state when inserted into the body so that it is secured behind the inner wall of the body near the opening in the body. This minimizes the likelihood that the opening of the device becomes detached from the patient. For example, in some embodiments, the ring may comprise a polymeric material that is resilient in nature. In some instances, the ring may further include a spring or spring-like structure made from metal, metal alloys, polymers, etc.
To remove the securing element, an operator (e.g., a physician, physicians assistant, etc.) may reach in and collapse the securing element so that it may be pulled back out of the opening in the body. It should also be appreciated that the securing element may be removed from the body opening by gently pulling on the surgical pouch with enough force to cause the securing element to collapse under pressure from the internal wall of the body at the body opening. The ease by which the securing element may be collapsed under such pressure will depend on how flexible, or how easily collapsible, the securing element is.
The surgical pouch may include various shapes. In some embodiments, the surgical pouch has a shape that is generally longer along the longitudinal axis than along the latitudinal axis. In some instances, the shape of the surgical pouch may be cylindrical or somewhat cylindrical. For example, the opening at the proximal end of the pouch may be circular and the body of the surgical pouch cylindrically extending from the circular opening. In some instances, the distal end of the surgical pouch is closed. For example, the distal end of the surgical pouch may be circular shaped. In other instances, a seam may be provided at the distal end of the surgical pouch that closes off the pouch along a line in the direction of the latitudinal axis.
In some embodiments, the surgical pouch includes a coupling element disposed on the distal end of the device that enables the device to removably couple to a structure so that it may hang above the body opening of the patient. The distal end of the pouch may hang above the proximal end of the pouch, causing the exposed internal body parts in the pouch to be displaced toward the proximal end of the pouch with the opening.
In some instances, the coupling element may comprise a layer of material having a hole within it that enables it to hang from a rod, hook, bar, etc., of an external structure, for example. The layer of material may also serve to reinforce the distal end of the pouch so that it may hang without ripping, tearing, or otherwise becoming damaged, and also serve to provide a seam that close off the distal end of the surgical pouch. The coupling element may comprise any variety of elements for various coupling mechanisms, such as clamps, hooks, hinges, adhesive, strings for tying, hooks, loops, snap-fit elements (e.g., buttons, etc.), etc.
In some embodiments, a seam may be provided along the two sides of the surgical pouch along the longitudinal axis. The seams, for example, may affect the shape of the cross section of the pouch when viewed from a line dividing the proximal end and distal end. The cross section may include, for example, the general shape of a circle, ellipse, or Vesica piscis, depending on the seam and/or shape of the proximal and distal end of the pouch. In some embodiments, where the shape of the above-described cross section is generally a Viseca piscis, certain sealing elements such as interlocking fasteners, for example, may be more easily sealed.
The surgical pouch should be large enough to fit the exposed internal body parts. While it is appreciated that there is no upper limit to the length of the surgical pouch, example lengths of the surgical pouch in Gastrochisis applications, for instance, may range from 6 inches to 30 inches, including 8 inches to 20 inches, such as 10 inches to 18 inches. It should also be appreciated that there is no upper limit to the width of the surgical pouch; however, example widths of the surgical pouch in Gastrochisis applications, for instance, may range from 1 inch to 6 inches, including 1.5 inches to 4.5 inches, such as 2 inches to 4 inches.
The opening in the pouch may vary in size, but should be large enough for the exposed internal body parts to fit through. Example opening sizes may range from 1 inch to 4 inches, such as 1.5 inches to 2.5 inches, including approximately 2 inches. In embodiments where the securing element is disposed around the opening, the size of the securing element may be, for example, approximately the size of the opening.
In use, the surgical pouch is placed around the exposed internal body parts of the patient. For example, the exposed internal body parts may be inserted into the opening of the surgical pouch by the operator (e.g., a physician or other medical personnel). In some instances, the opening may be stretchable or otherwise able to be widened to assist in the insertion of the exposed internal body parts into the surgical pouch.
After the exposed internal body parts are within the surgical pouch, the opening of the surgical pouch is secured to the patient. For example, the proximal end of the surgical pouch may include a securing element that is a collapsible structure that may be collapsed by the operator and inserted into the opening in the body of the patient. Once inside, the collapsible structure returns to its uncollapsed state and secures behind the internal wall of the body. In other embodiments, the opening may include adhesive sealing elements which enable the opening to be adhered to the body of the patient around the opening in the body.
In some instances, the distal end of the surgical pouch is raised up above the body opening. The surgical pouch may include, for example, a coupling element that couples the distal end of the surgical pouch to an external structure so that the distal end of the surgical pouch may be positioned above the proximal end. In such instances, gravity assists to displace the exposed internal body parts toward the proximal end of the surgical pouch—i.e., towards the opening of the surgical pouch.
In some instances, the exposed internal body parts do not fill the entire internal volume of the surgical pouch. As a result, when the body parts are displaced towards the proximal end of the pouch, the distal end of the pouch will include empty space. If the empty space at the distal end of the surgical pouch continues past a sealing element, then that sealing element may be sealed to seal off the empty section of the pouch. For example, the operator may slide an interlocking fastener to seal off the empty section of the pouch. If more than one sealing element is implemented and the empty space continues past multiple sealing elements, then each of those sealing elements may be sealed to close off a corresponding empty section of the pouch. It should be appreciated that only the sealing element that is closest to the proximal end, but still within the empty space, may be sealed to close off the corresponding empty section of the pouch.
In some instances, the distal end of the surgical pouch is not coupled to a structure so that the distal end of the surgical pouch is positioned above the proximal end. For example, the surgical pouch may be positioned next to the patient—e.g., on the table or bedside next to the patient. In such case, the exposed internal body parts within the pouch may be pushed towards the proximal end of the pouch by the operator. This forms the empty space at the distal end of the pouch, and the operator may then seal any sealing elements that the empty space continues past. In some instances, the operator may lift the distal end of the pouch in addition, or in place of, pushing the exposed internal body parts to the proximal end of the pouch. Lifting the distal end of the pouch displaces the exposed internal body parts towards the proximal end of the pouch, creating empty space at the distal end of the pouch. The operator may then seal any sealing element that the empty space continues past.
Over time, portions of the exposed internal body parts are inserted into the body opening. For example, a physician may slowly and gently press some of the exposed body parts within the body of the patient. In some instances, the exposed internal body parts may be swollen or inflamed, allowing more and more of the exposed internal body parts to be inserted into the body as the swelling and inflammation is reduced over time. As more of the exposed internal body parts are inserted into the body of the patient, more empty space is created at the distal end of the pouch. As the empty space grows and continues past an additional sealing element, the operator may seal off the additional sealing element to close off an empty section of the pouch that has formed when portions of the exposed internal body parts are inserted into the body of the patient. This may continue until all sealing elements have been sealed and the exposed internal body parts completely inserted into the body of the patient.
After the exposed internal body parts are inserted into the body of the patient, the securing element may be removed from the patient. For example, if the securing element comprises a collapsible structure, then the securing element may again be collapsed by the operator and removed out of the opening of the body while collapsed. In other instances, the operator may gently pull the surgical pouch away from the body opening, causing the sealing element to collapse under pressure against the body and to be removed from the body of the patient. In yet other instances, for example where the sealing element includes adhesive used to adhere the opening to the body of the patient, the operator pulls the sealing element from the body of the patient.
FIG. 1 illustrates a perspective view of a device for containing exposed internal body parts during insertion into the body, according to some embodiments. As shown, device 100 includes surgical pouch 110 and sealing elements 115a and 115b. A distal end 101 and proximal end 102 are shown for reference purposes. Also shown for reference purposes are a longitudinal axis L and a latitudinal axis W.
The surgical pouch is shown as a clear polymeric material, such as plastic or silicone.
Sealing elements 115a and 115b are shown disposed on the surgical pouch 100 at different positions along the longitudinal axis L. The sealing elements 115a and 115b are shown as interlocking fasteners that extend across the surgical pouch 110 in the direction of the latitudinal axis W. Sealing element 115a is disposed on the pouch 110 closer to the distal end 101 of the device 100 than sealing element 115b. As such, the two sealing elements 115a and 115b sectionalize the surgical pouch 110 into three sections A, B, and C.
Each of the sealing elements 115a and 115b may be sealed to seal off a corresponding section of the surgical pouch 100. For example, sealing element 115a enables section A to be closed off from the remaining portions—sections B and C—of the surgical pouch 110 when the internal body parts are not present in section A. Similarly, sealing element 115b enables section B to be closed off (and ultimately section A as well) from the remaining portion—section C—of the surgical pouch 110 when the internal body parts are not present in sections A and B.
The surgical pouch 110 also includes an opening 120 with a securing element 125 surrounding the opening. The securing element 125 is shown as a ring that is collapsible and resilient in nature. The ring 125 may be collapse to fit within the opening in the body (e.g., abdomen) of a patient. In such case, the ring 125 bends and deforms (e.g., to form a narrow elliptical shape) to enable the ring 125 to enter the opening in the body. The ring 125 may then return to its circular shape once inside the body to secure to the inner wall of the body. Ring 125 may be made from, for example, a polymeric material that is resilient so as to allow the ring 125 to collapse or deform and then return to its uncollapsed or undeformed state.
Device 100 also includes a coupling element 130 that is used to couple the distal end 101 of the device 100 to an external structure (not shown) so that the distal end 101 may hang above the proximal end 102 of the device 100. The coupling element 130 is shown comprising a layer of material that includes a hole 135 which may be used to hang the distal end 101 of the device 100 to the external structure.
FIG. 2 illustrates a perspective view of another exemplary device for containing exposed internal body parts during insertion into the body, according to some embodiments. As shown, device 100 includes surgical pouch 110 and sealing elements 115a, 115b, 115c, 115d, and 115e. A distal end 101 and proximal end 102 are shown for reference purposes. Also shown for reference purposes are a longitudinal axis L and a latitudinal axis W.
Sealing elements 115a, 115b, 115c, 115d, and 115e are shown disposed on the surgical pouch 100 at different positions along the longitudinal axis L. The sealing elements 115a, 115b, 115c, 115d, and 115e are shown as interlocking fasteners that extend across the surgical pouch 110 in the direction of the latitudinal axis W. The sealing elements 115a, 115b, 115c, 115d, and 115e are shown spaced apart with sealing element 115a disposed closest to the distal end 101 of the device 100, and with sealing element 115e disposed closest to the proximal end 102 of the device 100. As such, the sealing elements 115a, 115b, 115c, 115d, and 115e sectionalize the surgical pouch 110 into sections A, B, C, D, E, and F.
Each of the sealing elements 115a, 115b, 115c, 115d, and 115e may be sealed to seal off a corresponding section of the surgical pouch 100. For example, sealing element 115a enables section A to be closed off from the remaining portions—sections B, C, D, E, and F—of the surgical pouch 110 when the internal body parts are not present in section A. Sealing element 115b enables section B to be closed off (and ultimately section A as well) from the remaining portion—sections C, D, E, and F—of the surgical pouch 110 when the internal body parts are not present in sections A and B. Sealing element 115c enables section C to be closed off (and ultimately sections A and B as well) from the remaining portion—sections D, E, and F—of the surgical pouch 110 when the internal body parts are not present in sections A, B, and C. Sealing element 115d enables section D to be closed off (and ultimately sections A, B, and C as well) from the remaining portion—sections E and F—of the surgical pouch 110 when the internal body parts are not present in sections A, B, C, and D. And, similarly, sealing element 115e enables section E to be closed off (and ultimately sections A, B, C, and D as well) from the remaining portion—section F—of the surgical pouch 110 when the internal body parts are not present in sections A, B, C, D, and E. It should be appreciated that e number of sealing elements shown in FIGS. 1 and 2 are exemplary and that the number of sealing elements may vary in other embodiments.
The surgical pouch is shown as a clear polymeric material, such as plastic or silicone. The surgical pouch 110 also includes an opening 120 with a securing element 125 surrounding the opening. The securing element 125 is shown as a ring that is collapsible and resilient in nature. The ring 125 may be collapse to fit within the opening in the body (e.g., abdomen) of a patient. In such case, the ring 125 bends and deforms (e.g., to form a narrow elliptical shape) to enable the ring 125 to enter the opening in the body. The ring 125 may then return to its circular shape once inside the body to secure to the inner wall of the body. Ring 125 may be made from a polymeric material that is resilient so as to allow the ring 125 to collapse or deform and then return to its uncollapsed or undeformed state.
FIG. 3 illustrates a close-up perspective view of a securing element, according to some embodiments. As shown, securing element 125 comprises a ring disposed around the opening 120 of surgical pouch 110. Sealing element 115 is disposed on surgical pouch 110 distally from the securing element 125. In the embodiment shown, ring 125 includes a spring structure 126 made from a metal or metal alloy, for example. The spring 126 provides ring 125 with the collapsible and resilient properties that facilitate entry into the body opening and securing to inner wall of the body of the patient. The ring 125 is shown enclosed within the polymeric material of the pouch 110 surrounding the opening 120 of the pouch 110. In other embodiments, the securing element 125 may be coupled to the pouch by other means that attach, connect, or otherwise couple the securing element 125 to the pouch 110 near the opening 120.
FIGS. 4-7 illustrate a perspective view of the device shown in FIG. 1 at different times during use, according to some embodiments. Again, distal end 101 and proximal end 102 are shown for reference purposes. As shown in the figures, device 100 includes a surgical pouch 110 having sealing elements 115a and 115b. Sealing elements 115a and 115b are shown as interlocking fasteners. The surgical pouch 110 is shown sectionalized into three sections A, B, and C by sealing elements 115a and 115.
The exposed internal body parts 225 of baby 200 has been inserted within the surgical pouch 110 and contained therein. An opening (not shown) of the surgical pouch 110 is located at the proximal end 102 and inserted within the opening 220 of the abdomen 235 of baby 200. A securing element (such as the one shown in FIG. 3, for example, but not shown in FIGS. 4-7) is disposed around the opening of the surgical pouch 110 and is secured on the inside of the inner wall of the abdomen 235 of the baby 200. At the distal end 101 of the device 100 is a coupling element 130 that includes a hole 135 enabling the distal end 101 of the device 100 to hang from structure 250.
FIG. 4 illustrates a perspective view of the device shown in FIG. 1 containing exposed internal body parts 225 before either sealing element 115a or 115b are sealed. As shown, the exposed internal body parts 225 are contained within sections A, B, and C. Thus, both sealing elements 115a and 115b are left unsealed. The internal volume of the surgical pouch includes the exposed internal body parts 225 and empty space 205 at the distal end 101 of the surgical pouch 110.
FIG. 5 illustrates a perspective view of the device 100 shown in FIG. 4 after some exposed internal body parts 225 have been inserted within the baby 200 and sealing element 115a sealed. As shown, the exposed internal body parts 225 are contained only within sections B and C with empty space 205 in section A and in part of section B. Sealing element 115b is left unsealed and sealing element 115a is sealed to close off the empty space in section A.
FIG. 6 illustrates a perspective view of the device 100 shown in FIG. 4 after some exposed internal body parts 225 have been inserted within baby 200 and sealing element 115b sealed. As shown, the exposed internal body parts 225 are contained only within section C with empty space 205 in sections A and B and in part of section C. Sealing element 115a was previously sealed (e.g., as described in FIG. 4) to close off the empty space in section A, and now sealing element 115b is sealed to close off the empty space 205 in section B.
FIG. 7 illustrates a perspective view of the device 100 shown in FIG. 4 after all of the exposed internal body parts 225 have been inserted within the baby 100. As shown, section C of surgical pouch 110 is now empty since all of the exposed internal body parts 225 have been inserted within the opening 220 in the abdomen 235 of baby 200. The device 100 may now be removed from the baby 200. For example, the securing element (not shown) may be removed from the opening 220 of the baby 200. For example, the securing element comprises a collapsible structure and the securing element may be collapsed by the physician to be removed out of the opening of the body while collapsed. In other instances, the operator may pull the surgical pouch away from the body opening, causing the sealing element to collapse under pressure against the body and to be removed from the body of the patient.
In some aspects of the present disclosure, methods of containing exposed internal body parts of a human or veterinary patient during insertion into the body of the patient using are provided. In certain embodiments, the methods comprise inserting exposed internal body parts of a patient within a device including a surgical pouch and one or more sealing elements disposed on the surgical pouch. The methods also comprise displacing the exposed internal body parts toward the proximal end of the pouch and past a sealing element, such that the exposed internal body parts are proximally located to the sealing element. For example, portions of the exposed internal body parts of the patient are inserted within the body of a patient (e.g., the abdomen of a baby) and the internal body parts displaced towards the proximal end of the pouch. The methods also include sealing the sealing element disposed on the pouch when the exposed internal body parts are displaced past the sealing element, wherein an empty section of the pouch is closed off when the sealing element is sealed. In some embodiments, more than one sealing element is present and each sealing element may be sealed as the body parts are displaced past each sealing element.
The methods also comprise securing the surgical pouch to the patient using a securing element disposed on the device. In some instances, the proximal end of the surgical pouch may include a sealing element that is a collapsible structure that may be collapsed by the operator and inserted into the opening in the body of the patient. Once inside, the collapsible structure returns to its uncollapsed state and secures behind the internal wall of the body. In other embodiments, the opening may include adhesive sealing elements which enable the opening to be adhered to the body of the patient around the opening in the body.
In some instances, the distal end of the surgical pouch is raised up above the body opening. The surgical pouch may include, for example, a coupling element that couples the distal end of the surgical pouch to an external structure so that the distal end of the surgical pouch may be positioned above the proximal end. In such instances, gravity assists to displace the exposed internal body parts at the proximal end of the surgical pouch end—i.e., towards the opening of the surgical pouch.
In some instances, the exposed internal body parts do not fill the entire internal volume of the surgical pouch. As a result, the distal end of a surgical pouch may include empty space. If the empty space at the distal end of the surgical pouch continues past a sealing element, then that sealing element may be sealed to close off the empty section of the internal volume of the pouch. For example, the operator may slide an interlocking fastener to close off the empty section of the internal volume of the pouch. If more than one sealing element is implemented and the empty space continues past multiple sealing elements, then each, or any one, of those sealing elements may be sealed. It should be appreciated that only sealing the sealing element that is closest to the proximal end, but within the empty space, enables the remaining empty sections to be closed off as well.
In some instances, the distal end of the surgical pouch is not coupled to structure so that the distal end of the surgical pouch is positioned above the proximal end. For example, the surgical pouch may be positioned next to the patient—e.g., on the table or bedside next to the patient. In such case, the exposed internal body parts within the pouch may be pushed towards the proximal end of the pouch by the operator. This forms the empty space at the distal end of the pouch, and the operator may then seal any sealing elements that the empty space continues past. In some instances, the operator may lift the distal end of the pouch in addition, or in place of, pushing the exposed internal body parts to the proximal end of the pouch. Lifting the distal end of the pouch displaces the exposed internal body parts towards the proximal end of the pouch, creating empty space at the distal end of the pouch. The operator may then seal any sealing elements that the empty space continues past.
Over time, portions of the exposed internal body parts are inserted into the body opening. For example, a physician may slowly press some of the exposed body parts within the body of the patient. In some instances, the exposed internal body parts may be swollen or inflamed, allowing more and more of the exposed internal body parts to be inserted into the body as the swelling and inflammation is reduced over time. As more of the exposed internal body parts are inserted into the body of the patient, more empty space is created at the distal end of the pouch. As the empty space grows and continues past an additional sealing element, the operator may seal the additional sealing element to close off the additional empty sections that has formed from portions of the exposed internal body parts being inserted into the body of the patient. This may continue until all sealing elements have been sealed and the exposed internal body parts completely inserted into the body of the patient.
The subject devices and methods find use in a variety of different applications where internal body parts are exposed out of an opening in the body of a patient. In certain embodiments, the devices and methods are directed to containing exposed internal body parts of a newborn baby during insertion of the exposed internal body parts into the body of the baby.
Containing the exposed internal body parts with the subject devices and methods enable the exposed internal body parts to be shielded from trauma, infection, and dehydration until the body parts are put back within the body. Often the exposed internal body parts may be swollen and inflamed and require time before the swelling and inflammation subside to permit the internal body parts to be safely put back within the body.
As described above, the method may include inserting exposed internal body parts of a patient within a device including a surgical pouch and one or more sealing elements disposed on the surgical pouch; and displacing the exposed internal body parts toward the proximal end of the pouch and past a sealing element, such that the exposed internal body parts are proximally located to the sealing element. For example, portions of the exposed internal body parts of the patient are inserted within the body of a patient (e.g., the abdomen of a baby) and the internal body parts displaced towards the proximal end of the pouch. The methods also include sealing the sealing element disposed on the pouch when the exposed internal body parts are displaced past the sealing element, wherein an empty section of the pouch is closed off when the sealing element is sealed. In some embodiments, more than one sealing element is present and each sealing element may be sealed as the body parts are displaced past each sealing element.
The subject devices and methods may enable a single operator to more easily close off the empty section of the surgical pouch without the assistance of another person. Furthermore, the sealing elements are easily sealed and eliminate the cumbersome cinching and tying of the surgical pouch. Moreover, sealing elements such as interlocking fasteners ensures a “good” seal when sealed and are also well maintained thereafter.
Also provided are kits for use in practicing the subject methods, where the kits may include one or more of the devices described above. In some instances, the kits may include multiple devices with a different number of sealing elements disposed on the device. In some instances, the kits may include multiple devices with different sized devices. In some instances, the kits may also include a structure for hanging the device above the opening in the body of the patient. In some instances, the kits may include products used to sterilize or otherwise clean the body of the patient. Various components may be packaged as desired, e.g., together or separately.
