Description

FIELD OF THE INVENTION

The present invention relates, in general, to surgical trays and, more particularly, this invention relates to containers and protective covers for hypodermic needles and other devices for handling sharps employed during surgery and to an apparatus for holding a cautery tool as well as a tip cleaner for such cautery tool.

BACKGROUND OF THE INVENTION

Numerous inventions have been devised to assist operating room personnel in the handling of instruments, needles, scalpels, sutures, etc. employed during a surgical procedure. Particular concern is shown for suture needles, hypodermic needles, scalpel blades, etc., which are referred to in the art as “sharps”. Concern is also shown for placing these close to a surgical site in a manner which is convenient for the surgeon. One purpose of the application referenced above is to provide a transfer pad which eliminates hand to hand transfers. A surgeon can call for sharps or instruments, and an assistant places them on the transfer pad. The surgeon then picks them up from the transfer pad. Thus, the danger of fumbling a hand-to-hand transfer is substantially minimized.

Numerous prior art patents address safety issues related to sharps. For example, U.S. Pat. No. 5,538,132: “Guard Structure for Sharps” includes a magnet on which magnetic sharps can be safely placed. The sharps can be disposed of by folding, over the magnet, a layer having an adhesive, which seals against the magnet and the sharps on the magnet.

BRIEF DESCRIPTION OF THE PRESENTLY PREFERRED AND VARIOUS ALTERNATIVE EMBODIMENTS OF THE INVENTION

The following description of the invention sets forth specific embodiments which are described in sufficient detail to enable those skilled in the art to practice the present invention. It should be apparent to those skilled in the art that other embodiments may be utilized while remaining within the scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the invention is defined only by the appended claims.

FIGS. 1 and 2 illustrate a surgical pad and tray 10, which is a surgical aid that enables surgeons and other operating room personnel to place operating instruments and sharp items such as suture needles, scalpel blades and hypodermic needles close to a surgical site. Such items are referred to in the art as “sharps”.

The sharps are secured by a retention layer 28 overlying a puncture resistant layer 26. The retention layer 28 functions in the manner of a pincushion. Suture needles, hypodermic needles, scalpel blades and other sharps may be partially embedded in retention layer 28.

The surgical pad and tray 10 may be placed directly on the patient or on a drape covering the patient. To protect the patient from the sharps, the device includes puncture resistant layer 26 that underlies the retention layer 28.

The retention layer, preferably, has a low density and is fairly thick. For example only, its thickness may be in a range from about 9 mm to 12 mm. It is presently preferred that it be comprised of a cross linked polyethylene closed cell foam. Its density may be approximately 2 lbs/ft³ (32.03 kg/m³).

The puncture resistant layer 26 is relatively hard and dense to resist penetration by any of the sharps. It is presently preferred that the puncture resistant layer 26 be comprised of a high impact polystyrene. A rigid, high density polyethylene may alternatively be employed. For example only, the puncture resistant layer 26 may have an Izod impact strength rating of about 2 ft-lb in (0.1068 J/mm).

It is preferred that the puncture resistant layer 26 be a portion of a puncture resistant component 22 that includes the puncture resistant layer 26 and also a plurality of side walls 24 that surround retention layer 28 to provide greater strength near the edges of retention layer 28.

For additional convenience and ergonomic efficiency, the surgical pad and tray 10 further includes a tray 30 that is for a cautery tool. Tray 30 has a bottom 32, a long side 35 and short sides 36. The long side 35, preferably has a low central portion 36 to facilitate grasping the cautery tool 90.

FIG. 3 illustrates the invention employed to hold a cautery tool 90 as well as other sharps and implements. These include scalpel 82, scalpel blade 86, hypodermic needle 88 and suture needle 84.

Preferably, each short side 36 of tray 30 includes a notch 37. Notch 37 receives the handle of cautery tool 90, which is shown in FIG. 3. Preferably, notch 37 is not in the center of short side 36, but is displaced away from retention layer 28 to position the cautery tool away from retention layer 28, again, to facilitate grasping of the cautery tool 90. Preferably, each short side 36 of tray 30 includes a notch 37, so the cautery tool 90 can be placed in either direction. Tray 30, preferably, is sized so that when the handle of cautery tool 90 is placed in notch 37, the tip of the cautery tool (which may be hot) does not touch any portion of tray 30. This is to prevent fire, and to avoid contaminating the tip of cautery tool 90.

FIG. 2 shows the puncture resistant component 22 and the tray 30 comprised in an integral unit 20, which could be produced as a single unit. The entire integral unit 20 may be comprised of a high impact polystyrene or, alternatively, as a rigid, high-density polyethylene.

FIG. 1 further illustrates another presently preferred feature of the present invention. A non-skid layer 50 having a high friction surface 52, preferably, is included in the surgical pad and tray 10. Preferably, non-skid layer 50 includes an underlying portion 54 that underlies the puncture resistant component 22. Preferably, the underlying portion 54 of the non-skid layer 50 would be adhesively bonded to the underside of puncture resistant component 22. The non-skid layer 50 is for placement of Implements such as scalpel 82 shown in FIG. 3. It is presently preferred that non-skid layer 50 be flexible. A low density polyurethane is presently preferred.

Referring again to FIG. 1, another feature is preferably included with the invention. Preferably, the surgical pad and tray 10 includes a cautery tip cleaner 40, which the surgeon may employ to clean the tip of cautery tool 90. The cautery tip cleaner 40 preferably has a hard, abrasive surface. Cautery tip cleaner 40 may resemble a kitchen scouring pad. Preferably, it is bonded to the raised platform 42 that is comprised in integral unit 20 (shown in FIG. 2). The raised platform 42 is to provide a firm support for cautery tip cleaner 40.

FIGS. 4 and 5 illustrate an alternative embodiment of the present invention. The surgical pad and tray 70 includes a tray 30 disposed along one side of puncture resistant component 72, which holds retention layer 78. FIG. 5 illustrates integral unit 80, which is a component of the surgical pad and tray 70. Integral unit 80 includes a tray 30 integral with puncture resistant component 72. Preferably, puncture resistant component 72 includes a puncture resistant layer 76, which underlies retention layer 78. Preferably, puncture resistant component 72 also includes side walls 74, which serve to strengthen retention layer 78 near its edges. It is presently preferred that retention layer 78 be adhesively bonded onto puncture resistant layer 76. Preferably, integral unit 80 includes a raised platform 42 which is for cautery tip cleaner 40. The raised platform 42 provides firm support for cautery tip cleaner 40.

Integral unit 80 is preferably formed of high impact polystyrene. A rigid, high-density polyethylene may also be employed.

FIG. 4 also illustrates a non-skid layer 60, which has a non-skid surface 62. For the presently preferred construction, a portion 64 of non-skid layer 60 underlies integral unit 80 and is bonded to it.

FIG. 6 illustrates the back side of surgical pad and tray 10, and shows a universal mounting system 14, which comprises a sticky material covered by tape. By employing the universal mounting system 14, the surgical pad and tray 10 can be attached to a drape adjacent the surgical site, or may be adhered to the patient's skin. Prior to placement on the drape or the patient, the tape is removed to expose the sticky material.

When the surgical pad and tray 10 or 70 is produced, an integral unit 20 comprising puncture resistant component 22 and tray 30 at the top is produced, or the integral unit 80 comprising puncture resistant component 72 with tray 30 on the side is produced. The non-skid layer 50 or the non-skid layer 60 is then cut to size. Then, integral unit 20 is bonded to non-skid layer 50, or the integral unit 80 is bonded to the non-skid layer 60.

Retention layer 28 is then bonded to the puncture resistant layer 26 of puncture resistant component 22, or retention layer 78 is bonded to the puncture resistant layer 76 of puncture resistant component 72. The cautery tip cleaner 40 is then bonded to the retention layer 28. The bonding steps may be done in any sequence or simultaneously. Adhesive bonding is presently preferred. An alternative method of bonding is thermal bonding.

It should be recognized that the above-mentioned embodiments of the invention and the methods of making it are intended to be illustrative only. Numerous alternative embodiments may be devised by those skilled in the art without departing from the scope of the following claims.
