The inner tray is configured to fit within the outer case and is releasably attached to the outer case. The handle is securely coupled to the inner tray such that the surgical instrument tray assembly, including the outer case and the inner tray, is transportable with a single hand by engaging the handle.

## Background
FIELD
The present disclosure relates to instrument cases, and more particularly, to cases for organizing, storing, cleaning, and/or transporting surgical instruments.
BACKGROUND
This section provides background information related to the present disclosure which is not necessarily prior art.
Surgical instrument trays are used to organize, store, clean, and transport surgical instruments. The trays are generally contained in a case. Surgical instrument trays can contain the tools necessary to prepare, insert, and remove implants such as an acetabular cup. A single implant system can require several trays of instruments to perform these tasks. The multiple trays and/or cases can clutter an operating room and cause delays during surgery as surgical technicians search through multiple trays to find a desired instrument. Although cases with multiple, stackable inner trays have been developed, these cases can be difficult to sort through when searching for a desired instrument.
Handles of instrument trays or cases are typically located at outside ends or sides of the trays or cases. For example, an instrument tray can include one handle attached to one end of the tray and a second handle attached to the opposite end of the tray. Thus, a surgeon or surgical technician must use two hands to lift and move the trays or cases.
SUMMARY
This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.
An example of a surgical instrument tray assembly according to the principles of the present disclosure includes an outer case, an inner tray, and a handle.

DETAILED DESCRIPTION
Example embodiments will now be described more fully with reference to the accompanying drawings.
Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.
Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
An instrument case according to the principles of the present disclosure can include an outer case, an inner tray, a case lid and/or a handle. The handle can be modular and/or can be rigidly fixed or hinged to the outer case, the inner tray, or the case lid. The handle can be positioned to allow the instrument case to be moved or repositioned using a single hand of a user (e.g., a human person). For example, the handle can be positioned at or near the gravitational center and/or balance point of the instrument case. This configuration makes it easier to find an instrument and thereby reduces delays associated with finding an instrument. In addition, this makes transport of the instrument case efficient for others that may handle the instrument case, such as sales associates selling surgical instruments and/or instrument cases to medical professionals.
Referring now to FIGS. 1A, 1B, and 2, an instrument case 10 includes an outer case 12, an inner tray 14 that is configured to fit within the outer case 12, a handle 16 coupled to the inner tray 14, and a case lid 18. The outer case 12 can form a rectangular box having a floor or bottom 20 closing one end of the outer case 12, sides 22 extending from the bottom 20, and an open top 24. The inner tray 14 can form a rectangular box having a floor or bottom 26 closing one end of the inner tray 14, sides 28 extending from the bottom 26, and an open top 30.
The handle 16 can be modular and/or can be rigidly fixed or hinged to the inner tray 14. The handle 16 can extend beyond the open top 30 of the inner tray 14, such as outside and/or above the sides 28 of the inner tray 14 The handle 16 can include attachment portions 32 and a gripping portion 34. The attachment portions 32 and the gripping portion 34 can be formed as a unitary member or separately formed and connected together. The attachment portions 32 can be attached to the inner surface of the bottom 26 of the inner tray 14. The attachment portions 32 can be attached to the inner tray 14 using fasteners (e.g., rivet, screws) and/or an adhesive.
The gripping portion 34 can be U-shaped with outwardly extending ends 36 and can be rigidly fixed or hinged to the attachment portions 32. The gripping portion 34 can be rigidly fixed to the attachment portions 32 using fasteners and/or an adhesive, or by forming the attachment portions 32 and the gripping portion 34 as a unitary member. The gripping portion 34 can be hinged to the attachment portions 32 by capturing the ends 36 of the gripping portion 34 within the attachment portions 32 while allowing the ends 36 to rotate relative to the attachment portions 32. The gripping portion 34 can also include an ergonomic holding portion, such as a cushioned member.
The case lid 18 can be configured to fit over the open top 24 of the outer case 12 to at least partially enclose the interior of the outer case 12. The case lid 18 can have an open bottom 38, a closed top 40, and sides 42 extending from the closed top 40. The open bottom 38 of the case lid 18 can be configured to receive the open top 24 of the outer case 12 such that the sides 42 of the case lid 18 overlap with the sides 22 of the outer case 12. The case lid 18 can be releasably attached to the outer case 12 using a press or interference fit or a releasable latch 43 (e.g., a locking latch).
The latch 43 can include a first rotating member 43a, a second rotating member 43b, and a keeper or strike 43c. To secure the latch 43, a user can rotate the first rotating member 43a into engagement with the strike 43c, and then rotate the second rotating member 43b toward the outer case 12 to apply tension to the first rotating member 43a. This tension maintains the engagement between the first rotating member 43a and the strike 43c. To release the latch 43, a user can rotate the second rotating member 43b away from the outer case 12 and then rotate the first rotating member 43a out of engagement with the strike 43c.

The case lid 208 can be configured to fit over the open top 216 of the outer case 202 to enclose the interior of the outer case 202. The case lid 208 can form a rectangular box having an open bottom 230, a closed top 232, and sides 234 extending from the closed top 232. The open bottom 230 of the case lid 208 can be configured to receive the open top 216 of the outer case 202 such that the sides 234 of the case lid 208 overlap with the sides 214 of the outer case 202. The case lid 208 can be releasably attached to the outer case 202 using a press or interference fit and/or a releasable latch 236 (e.g., a locking latch) disposed on opposite sides of the instrument case 200.
The latch 236 can be a toggle latch that can include a first rotating member 238, a second rotating member 240, and a keeper or strike 242. To secure the latch 236, a user can rotate the first rotating member 238 into engagement with the strike 242, and then rotate the second rotating member 240 toward the outer case 202 to apply tension to the first rotating member 238. This tension maintains the engagement between the first rotating member 238 and the strike 242. To release the latch 236, a user can rotate the second rotating member 240 away from the outer case 202 and then rotate the first rotating member 238 out of engagement with the strike 242.
The handle 210 can be positioned at or near the center of the case lid 208 such that the instrument case 200 can be transported using a single hand of a user. For example, when the case lid 208 is attached to the outer case 202, the handle 210 can be used to move the outer case 202, which may contain the inner trays 204. The handle 210 can be modular such that the handle 210 is efficiently separable form the outer case 202. In addition or alternatively, the handle 210 can be rigidly fixed or hinged to the case lid 208. The handle 210 can include attachment portions 244 and a gripping portion 246. The attachment portions 244 and the gripping portion 246 can be formed as a unitary member or separately formed and connected together. The attachment portions 244 can be attached to the outer surface of the closed top 232 of the case lid 208. The attachment portions 244 can be attached to the case lid 208 using fasteners and/or an adhesive, as discussed above.
The gripping portion 246 can be U-shaped with outwardly extending ends 248 and can be rigidly fixed or hinged to the attachment portions 244. The gripping portion 246 can be rigidly fixed to the attachment portions 244 using fasteners and/or an adhesive, as discussed above, or by forming the attachment portions 244 and the gripping portion 246 as a unitary member. The gripping portion 246 can be hinged to the attachment portions 244 by capturing the ends 248 of the gripping portion 246 within the attachment portions 244 while allowing the ends 248 to rotate relative to the attachment portions 244.
