BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention pertains to instrument tray systems; more particularly, the present invention pertains to instrument tray systems associated with medical/surgical systems.
2. Description of the Related Art
A common accessory associated with medical/surgical systems, and more particularly ophthalmic surgical systems such as phacoemulsifiers and vitrectomy units, is a reusable tray system. These reusable instrument tray systems are typically made from either stainless steel or an autoclavable plastic. The instrument tray systems are designed to interface with an articulating arm and tray support attached to the surgical system. Many tray systems contain pockets or cavities sized and shaped to hold the various instruments, devices, handpieces and consumables used during a specific surgical procedure.
While many prior art tray systems are in use, problems still remain with such tray systems.
Some of the problems with commonly available instrument tray systems are:

    
    
        a) the instrument tray system is too small to hold all of the needed instruments, devices, handpieces and consumables associated with a specific surgical procedure;
        b) The instrument tray system is too large to fit into available autoclave sterilizers;
        c) The hard surface of the instrument tray system can damage delicate instruments used in a surgical procedure.
    
    


Accordingly, a need remains in the art for an instrument tray system which solves the foregoing problems.
BRIEF SUMMARY OF THE INVENTION
The disclosed medical equipment tray system is large enough to hold a complete set of needed instruments, devices, handpieces and consumables; fits within an autoclave sterilizer; and will not damage delicate instruments. The disclosed tray system includes a foldable platform, a foldable liner, and an elevatable handpiece cradle.

DETAILED DESCRIPTION OF THE INVENTION
The medical equipment tray system 10 of the preferred embodiment of the present invention as shown in FIG. 1 includes three parts: a platform portion 20, a foldable liner 40, and a handpiece cradle 60.
The platform portion 20 of the tray system 10 is preferably an injected molded part made out of an autoclavable plastic material. Two platform sections 22, 24 as shown in FIGS. 2 and 3 preferably form each tray system 10. Each section has a male and female hinge 26, 28 that join platform sections 22, 24 together as shown in FIG. 3. A lock on the male hinge 26 of one section interfaces with the female hinge 28 of the other section to keep the joined platform in an open position as shown in FIG. 3. By bringing the opposing sides of the platform sections together, the lock is overcome and the platform is allowed to fold so that section 24 rests on section 22, as shown in FIG. 4. Male and female button locks 30 are used to keep the folded platform in a closed position until the platform 20 is opened using the finger relief 31 formed by the two folded platform sections 22, 24.
The foldable liner 40 shown in FIG. 5 is preferably a molded component made out of silicon elastomer. Foldable liner 40 provides the surface that is used to position the instruments, devices, handpieces and consumables that may be used during a surgical procedure. Accordingly, the foldable liner 40 includes a plurality of projections 42, 44 extending upwardly therefrom. Projections 42, 44 have spaces therebetween that enable the organization and positioning of the instruments, devices, handpieces and consumables to be used. The soft upper surface 46 of the foldable liner 40 protects the various devices placed thereupon from damage. The foldable liner 40 press fits into openings such as linear cuts 32 and round holes 34 found in the platform 20 as shown in FIGS. 3 and 6. The foldable liner 40 is molded to be thinner along a centrally located hinge line 44-48 which is positioned over that portion of molded platform 20 where the two sections 22, 24 come together. This hinge line 44-48 allows the foldable liner 40 to fold more easily when the molded platform 20 is folded into its sterilization position as shown in FIG. 4.
The handpiece cradle 60 is an injected molded part made out of an autoclavable plastic material as shown in FIGS. 7 and 8. The handpiece cradle 60 has spaces 62, 64 on which surgical handpieces, such as an ultrasonic handpiece or an irrigation/aspiration handpiece, may be placed. The handpiece cradle 60 has a handle 66 and male hinge portions 68. The male hinge portions 68 assemble into female hinge portions 36 on the platform 20 as shown in FIG. 8. These female hinge portions 36 protrude through cutouts 50 in the foldable liner 40. When the handpiece cradle 60 is assembled to the platform 20, it can be elevated to a vertical position via handle 66, as shown in FIG. 9. Locks on the female hinge portions 36 lock the elevatable handpiece cradle 60 in its vertical position as well as in its horizontal position, as shown in FIG. 1. The elevatable handpiece cradle 60 facilitates priming of the ultrasonic and/or irrigation/aspiration handpieces.
In the unfolded position, the tray system 10 can be used as a procedural set-up tray that can be placed on support 92 such as a table or Mayo stand at the end of an articulating arm 90 of a medical/surgical system 100, as shown in FIG. 11. The tray system 10 is sized so that it can fit onto either a large or a small Mayo stand. Molded features 35 on the bottom 38 of the platform 20 locate and secure the tray system 10 to a large Mayo stand. Molded features 37 on the bottom 38 of the platform 20 locate and secure the tray system 10 to a small Mayo stand.
While the medical equipment tray system of the present invention has been described by reference to its preferred embodiment, those of ordinary skill in the art will understand that the foregoing disclosure embodies other embodiments. Such other embodiments shall be included within the scope and meaning of the appended claims.
