More particularly, the present invention relates to instrument trays for medical supplies and devices and brackets that engage the trays to facilitate installation and removal of the brackets from the trays.
- 2. Description of Related Art
- Medical device instrument trays, for example, for use in operating rooms or emergently rooms, to facilitate access and handling of medical supplies and device are common in the art. Some prior art trays may include brackets or structures that can be mounted to the tray to provide supports or cavities of retaining or locating medical supplies and/or devices. For example, a broad variety of medical instrument trays having some form of bracket structure can be found in the patent literature. U.S. Pat. No. 6,382,575 B1 issued to Frush, et al. and U.S. Pat. No. 6,048,503 issued to Riley, et al. are representative of the prior art. Frush discloses a medical instrument bracket that includes a “
clip part 12” and a “holder part 14” that cooperate to retain a bracket in a tray. Riley discloses brackets or fixtures that “plug into” a tray. However, neither Frush nor Riley, nor any of the other references encountered, provides the advantages of the present invention. - Aspects of the present invention provide tray assemblies and tray brackets that facilitate the handling and manipulation of brackets and related structures mounted in a tray.

According to one aspect, the bracket may be adapted to “snap into” the planar surface, for example, releasably or removably snap into the planar surface of the instrument tray assembly. In one aspect, the bottom of the support bracket may be positioned below the planar surface when the at least some of the plurality of side walls of the support bracket engage the planar surface. In another aspect, the plurality of side walls may be outwardly biased, cantilevered projections positioned to engage at least one of the one or more perforations. In one aspect, the instrument tray assembly may be a medical device instrument tray assembly, though other uses for aspects of the invention are envisioned.
- Another aspect of the invention is a an instrument tray support bracket having a bottom and a plurality of side walls extending from the bottom, the plurality of side walls adapted to engage a perforation in a planar surface of an instrument tray to secure the support bracket to the planar surface of the instrument tray. For example, in one aspect, the plurality of side walls may include outwardly biased, cantilevered projections positioned to engage a perforation in the instrument tray. In another aspect, the outwardly biased, cantilevered projections may engage ends of an elongated perforation in the instrument tray or the outwardly biased, cantilevered projections may be the outwardly biased projections in opposing side walls.
- A further aspect of the invention is a method of engaging a bracket into a instrument tray by inserting a bracket having a plurality outwardly-biased, cantilevered projections into a perforation in the instrument tray; contacting the plurality of projections with edges of the perforation in the instrument tray and inwardly deflecting the outwardly-biased projections; passing the outwardly-biased projections through the perforation; allowing the outwardly-biased projections to outwardly deflect; and engaging the instrument tray with the outwardly-deflected projections. In one aspect, the method may further include, after passing the projections through the perforation, contacting the instrument tray with a second projection on the bracket whereby the bracket is retained on the instrument tray between the outwardly-deflected, outwardly-biased projection and the second projection.
- Though aspects of the invention may be particularly useful for retaining and handling medical supplies and devices, aspects of the invention may be applied to any field that can benefit from a tray having brackets or other support structures.
