The present invention relates to accessories for surgical instruments. More particularly, the present invention provides a two-tiered instrument table and a unitary drape for covering such a table.
Tiered surgical instrument tables provide medical personnel access to surgical equipment and supplies for use during a surgical procedure.
Tiered surgical tables can be difficult to drape properly. Often, several drapes sheets are placed in overlapping relation. Alternatively, at least one fitted surgical drape is available for draping a tiered surgical table so as to isolate the sterile lower tier surface from a contaminated underside surface of the upper tier. The fitted drape includes a bottom sheet that covers the lower tier and a top sheet that covers the upper tier. A middle sheet, which attaches to the top surface of the bottom sheet and to a front edge of the top sheet, spans the open gap between the two tiers. However, this drape has drawbacks to its use, as there are open gaps on the sides of the drape between the tiers and proper installation is not readily accomplished.
Accordingly, there is a need in the art for an improved drape to cover tiered surgical tables. It is to such that the present invention is directed.
Wherefore, it is an object of the present invention to overcome the above mentioned shortcomings and drawbacks associated with the prior art.
An object of this invention is to provide a tiered table for a surgical environment, and a sterile fitted drape specifically designed for the table.
Another object of the invention is to simplify the draping procedure, and to make drape removal quick and easy.
Other objects, advantages, and features of the present invention will become readily apparent from the following detailed description in conjunction with the drawings and the appended claims.
The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate various embodiments of the invention and together with the general description of the invention given above and the detailed description of the drawings given below, serve to explain the principles of the invention. The invention will now be described, by way of example, with reference to the accompanying drawings in which:
It should be understood that the drawings are not necessarily to scale and that the disclosed embodiments are sometimes illustrated diagrammatical and in partial views. In certain instances, details which are not necessary for an understanding of this disclosure or which render other details difficult to perceive may have been omitted. It should be understood, of course, that this disclosure is not limited to the particular embodiments illustrated herein.
The present invention will be understood by reference to the following detailed description, which should be read in conjunction with the appended drawings. It is to be appreciated that the following detailed description of various embodiments is by way of example only and is not meant to limit, in any way, the scope of the present invention.
With reference to
The chassis 10 comprises a pair of horizontal side rails 12, 14, which diverge slightly toward the rear of the chassis. The side rails are interconnected by front and rear rails 16, 18. A pair of parallel horizontal members 20, 22 extend between the front and rear rails inboard of the side rails. The members 20, 22 support front and rear braces 24, 26, which diverge upwardly from the struts. Neither brace is vertical; the forward brace leans toward the front of the chassis, and the rear brace leans toward the rear. Each brace is formed from a pair of parallel tubes 28, 30, welded to either end of a horizontal bar 32.
Lockable casters 34, attached to either end of the left and right rails, provide rolling support for chassis. Some or all of the casters may have kingpins 36 (
A tray 40, preferably in the form of a metal grill, is fitted in the rectangular area between the struts and the front and rear rails. Alternatively, the grill could be made of expanded metal, or might be a molded plastic element,
The table tops are supported by a pair of parallel spaced side panels 42, 44, made of sheet metal, which bear against the ends of the horizontal bars 32 and are affixed thereto by fasteners such as bolts. Horizontal handlebars 46, 48 (
The top edges of the side panels have inwardly turned horizontal flanges 50, 52. The table tops rest on these flanges, to which they are connected by rivets or removable fasteners 54.
As shown each of the table tops is non-adjustably supported by the chassis, and the tops are situated at different heights so that one top is higher and one top is lower. Additionally, the tops are non-parallel, with the front edge of the higher top lying substantially above the rear edge of the lower top.
The front table top 60 has an aperture 62 for receiving a kidney basin, and a pair of holes 65 for receiving specimen cups 66. Such receptacles are preferably built into the drape described below. Two basin holes 68 are also provided, at opposite ends of the table top 60; these accept basins 69 intended to receive corresponding receptacles built into the drape.
The rear table top 80 has an upturned front edge flange 82, to keep instruments from rolling off, and a downturned rear edge flange 84.
At the rear of the frame, a pivotal bucket bracket assembly 90 is clamped to one of the tubes 54, 56. The bracket has a hinge 92, not shown in detail, so that a “kick bucket” 93 held by the bracket may be swung out the way when necessary. A hoop 94 for receiving the bucket is secured to the hinge by a pair of welded arms 96, 98.

The sterile barrier 150, initially accordion folded and removably attached to the drape panel 114, has a broad band of adhesive 160 applied to the rearmost (top of Brace 8) bottom edge of the rear panel 152, for securing the panel to the rear table top.
The barrier comprises two panels 152, 154 (
The sterile barrier 150, accordion folded as shown in
The barrier can be removed to expose the sterile table and instruments on the table by peeling the two panels 152, 154 apart, after gripping the panels at the “TEAR HERE” decals 158.
While this invention has been described in terms of illustrated embodiments, it will be apparent to those of skill in the art that variations and modification may be made without departing from the concept, spirit and scope of the invention. It is therefore intended that the invention be defined by the appended claims.
