Description

FIELD OF THE DISCLOSURE

The present disclosure is generally related to brackets and more particularly is related to a tray and bracket system and related methods.

BACKGROUND OF THE DISCLOSURE

There exists in the prior art various retainers and accessories for fixing the positions of articles of one kind or another. These include hooks, pegs, clips, brackets, etc. Such retainers may be used in a wide variety of applications. For example, they are commonly used in the medical field to fix the positions of various surgical instruments, devices and prostheses while those articles are being transported, sterilized and processed in one way or another.

Medical instruments are often transported in trays. Prior to use, such instruments are placed in the tray and subjected to sterilization. To improve the circulation of steam throughout the tray, the tray bottom wall and perhaps also the side wall are usually perforated. In order to maintain a separation between the various instruments in the tray, the instruments are supported or retained by posts, brackets or other retainers anchored to the tray. Following sterilization, the tray full of instruments may be transported to an operating room and placed close to a surgical team whose members may withdraw the instruments from the tray as needed for the particular surgical procedure being performed. Usually, the instruments are selectively arranged or organized in the tray so that they can be picked from the tray in the order in which they are needed for the particular procedure.

Sterilization trays may come in a variety of configurations, such that they can hold a number of different instruments. While the companies that require sterilization trays may assemble bracketry themselves, it often is a cumbersome process, since it requires positioning and connecting each bracket, which often has multiple parts. Additionally, once the bracket is assembled, it may become necessary to remove the bracket from the tray to properly sterilize it. Bracketry that uses multiple pieces can be time consuming to assemble and disassemble, which results in inefficiencies with using the tray. These inefficiencies may waste time and money.

Thus, a heretofore unaddressed need exists in the industry to address the aforementioned deficiencies and inadequacies.

FIG. 1 is plan view illustration of a bracket 30 of the bracket system 10, in accordance with a first exemplary embodiment of the present disclosure. FIG. 2 is partial cross-sectional view illustration of a bracket 30 connected to the tray 20 of the bracket system 10, in accordance with the first exemplary embodiment of the present disclosure. FIG. 3 is bottom plan view illustration of a bracket 30 connected to the tray 20 of the bracket system 10, in accordance with the first exemplary embodiment of the present disclosure. FIG. 4 is top plan view illustration of a bracket 30 connected to the tray 20 of the bracket system 10, in accordance with the first exemplary embodiment of the present disclosure.

With respect to FIGS. 1-4, the bracket system 10, which may be referred to herein as ‘system 10’ includes a tray 20 having a plurality of connector holes 22 positioned therein, wherein the tray 20 has an upper surface 24 and a lower surface 26. A bracket 30 has a base surface 32 positioned proximate to an upper surface 24 of the tray 20. At least one fastening tab 40 is formed on the base surface 32 of the bracket 30, wherein the at least one fastening tab 40 extends away from the base surface 32 and through at least one of the plurality of connector holes 22 within the tray 20. An interior corner pocket 50 is formed by the at least one fastening tab 40 and is located at least partially between the base surface 32 and the at least one fastening tab 30, wherein an exterior corner 60 (Shown in FIG. 5) of at least one of the plurality of connector holes 22 is positioned with the interior corner pocket 50. A retainer structure 70 is formed on the base surface 32 of the bracket 30, wherein the retainer structure 70 engages with the tray 20 to retain the exterior corner 60 positioned within the interior corner pocket 50.

The tray 20 may have any size or dimension, and may commonly include tray walls positioned around a substantially planar middle section. The tray 20 includes a plurality of connector holes 22 positioned within the tray 20, and may include a plurality of other holes for allowing the ingress and egress of sterilization fluid or materials during a sterilization process. The connector holes 22 may be positioned within the tray 20 and between the upper surface 24 and the lower surface 26, which are positioned in opposing directions from one another.

The bracket 30 is a rigid, partially rigid, or slightly flexible structure that is capable of holding a medical instrument, or other implement that is placed within the tray 20. While not shown, the bracket 30 may include any features or structures for holding the medical instrument. The bracket 30 has a base surface 32 that is positioned proximate to an upper surface 24 of the tray 20, such as in an abutting position on the upper surface 24. The bracket 30 can, of course, be removed from a location on the tray 20, in which case the base surface 32 of the bracket 30 would not be positioned proximate to the upper surface 24.

A fastening tab 40, or more commonly a plurality of fastening tabs 40, is formed on the base surface 32 of the bracket 30 and extends away from the base surface 32. The fastening tab 40 allows the bracket 30 to be connected to the tray 20, by engagement between the fastening tab 40 with the connector hole 22. This connection between the fastening tab 40 the connector hole 22 within the tray 20 is removable, such that the bracket 30 can be removed from the tray 20 when necessary, such as when cleaning of the bracket 30 or tray 20 is required. The fastening tab 40 may have a variety of shapes and sizes, but may generally be sized smaller than the base surface 32 of the bracket 30, such that when the fastening tab 40 is connected with the connector hole 22, the base surface 32 sits flush on the upper surface 24 of the tray 20.

While the fastening tab 40 may include various structures, at least one interior corner pocket 50 is formed by the fastening tab 40. This interior corner pocket 50 may be characterized as a structure of the fastening tab 40 where three or more surfaces intersect at an angle that is less than 180°. As is shown in FIGS. 1-2 and FIG. 5, the interior corner pocket 50 may include three surfaces that intersect at 90° angles relative to one another. It may be common for each fastening tab 40 to have two interior corner pockets 50 that are formed on opposing sides of a central wall 52, whereby opposing sides of the central wall 52 each form one of the three sides of the interior corner pocket 50. A top wall 54 may be positioned at an end of the fastening tab 40 and connected to the central wall 52, and act as another side for the interior corner pocket 50. In other words, the fastening tab 40 may include a T-shaped wall with a covering thereon, wherein the interior corner pocket(s) 50 are formed between the leg and arms of the T-shaped wall and the covering thereon. The interior corner pocket 50 is located at least partially between the base surface 32 and the at least one fastening tab 30.

The interior corner pocket 50 may engage with an exterior corner 60 of at least one of the plurality of connector holes 22 of the tray 20. In other words, the connector holes 22 may have a cutout T-shape, whereby the leg of the T-shape can receive the central wall 52 of the fastening tab 40. The exterior corners 60, e.g., the sides of the connector holes 22 forming the leg cutout of the T-shape, can be sized to fit within the interior corner pockets 50 when the fastening tab 40 is engaged with the connector hole 22.

A retainer structure 70 is also formed on the base surface 32 of the bracket 30. The retainer structure 70 engages with the tray 20 to retain the exterior corner 60 positioned within the interior corner pocket 50. For example, the retainer structure 70 may include a positive ramp extending from the base surface 32, which makes contact with a rear sidewall of the connector hole 22 when the fastening tab 40 is positioned within the connector hole 22, as is best shown in FIG. 2. The retainer structure 70 may prevent the fastening tab 40 from moving within the connector hole 22, thereby keeping the exterior corners 60 of the tray 20 positioned within the interior corner pockets 50. In other words, the retainer structure 70 can be used to lock the fastening tab 40 within the connector hole 22. Other designs for the retainer structure are available, as is discussed relative to FIGS. 6-11.

FIG. 5 is bottom view illustration of the bracket system 10, in accordance with the first exemplary embodiment of the present disclosure.
