ELONGATED SURGICAL INSTRUMENT HOLDER BACKGROUND OF THE INVENTION l. Field of the Invention This invention relates to improvements in a holder for elongated surgical instruments to be used in sterile environments and during cleaning and storage of the instruments, and more particularly to improvements in holders to thereby minimize structural damage and bacteriological contamination resulting from handling by medical personnel during cleaning and storage of the instruments.

2. Description of the Prior Art Hospitals, medical centers, and doctors offices employ rigorous procedures with respect to handling, cleaning, sterilizing, and maintaining instruments and equipment for medical, surgical and operating use. Naturally, the most important overall consideration is preserving cleanliness and sterility of the instruments and operating equipment prior to use. In the prior art, an operating room is prepared for surgery by first locat ing a back table generally away from the site at which the primary operating activity is to be conducted. The particular instruments required in the surgery, just prior to the operation, are removed from a protective prophylactic wrapper in which they are stored and arranged in readily accessible fashion on the back table. A second smaller table, frequently called a Mayo table is then positioned near the site of the operation, and during the course of the operation various surgical instruments are brought forward from the horizontal array of instruments on the back table and positioned on the Mayo table thereby providing the operating doctor or his assistant immediate access to the particular instruments as they are needed.

During the course of an operation, the instruments may become soiled by blood and other operating debris, which may cake or harden thereon and may be difficult to remove. Consquently, to ease subsequent cleaning processes, after use the instruments may be immediately dropped into a soaking solution to prevent blood or other operating debris from caking or hardening thereon.

After an operation, the used instruments may be cleaned by hand or machine washing, or by any other frequently used cleansing procedure. Because of the physically limited process involved in storing, carrying, and handling the instruments, the presently used cleaning methods have a number of disadvantages and consequent limitations. For example, hand washing, the most frequently used cleaning method, involves brushing and scrubbing each instrument in a soap solution to remove accumulated operating materials and debris. Clearly, such hand washing provokes an inherently high risk of damage to the instruments, particularly those with sharp and delicate edges. To mitigate and correct for these disadvantages, ultrasonic cleaning procedures have been developed for surgical instru ments. As an illustration, in my US. Pat. No. 3,640,295, a surgical instrument case including a grid assembly disposed therein is shown for holding instruments during surgical procedures or during cleaning and storage of those instruments. The structure of the grid assembly holder shows a plurality of vertically extending pegs to laterally secure a horizontal array of surgical instruments. Consequently, surgeons using that particular type of holder stack one instrument on top of another.

The prior art shows an unrelated variety of supporting stands for surgical or other instruments. For example, an 1888 US. Pat., Leonard, No. 391,540, shows an improvement in cases for surgical, mathematical, and other instruments and apparatus. That patent simply shows a plurality of clamps secured to a plate or other flat surface for holding the handles of instruments secured thereby. The prior art additionally shows a supporting stand for instruments, Dold, US. Pat. No. 3,564,662, having a plurality of clamping sleeves secured to individual levers pivitol on a shaft. That device thereby provides for the clamping sleeves to be pivotal about the shaft whereby one end of each clamping sleeve can be raised to a position facilitating the insertion or retraction of an instrument to be held by that particular device. Other stands and holders are shown in the prior art, but as the Dold patent, fail to indicate or suggest any means for both laterally and longitudinally securing surgical instruments in a holder, both during surgical procedures as well as during cleaning and storage of the instruments.

SUMMARY OF THE INVENTION In view of the above, it is an object of the invention to present a holder for elongated surgical instruments for use during surgical procedures and during cleaning and storage of the instruments, thereby minimizing material and structural damage and bacteriologicalcontamination otherwise resulting from handling by medical personnel during cleaning and storage of the instruments.

It is a further object of the invention to present a holder for use during a surgical procedure wherein a surgical instrument is secured in the holder until used in the procedure, and after its use therein, is immedi ately resecured in the holder, thereby minimizing damage and contamination otherwise resulting from handling by medical personnel during cleaning and storage of the instrument.

It is a still further object of the invention to present a holder for use in combination with an existing surgical instrument cleaning device.

It is yet a further object of the invention to present a holder for use in combination with an existing ultrasonic surgical instrument cleaning device.

It is still a yet further object of the invention to present a selectively foldably-collapsible holder for use in combination with an existing surgical instrument case.

It is another object of the invention to present a means of securing pivoted, pincer-like surgical instruments having two elongated members pivotally joined in a partially opened position to facilitate cleaning of the instruments when held by the invention.

These and other objects, features, and advantages of the invention will become apparent to those skilled in the art from the following detailed description when read in light of the attached drawing and appended claims.

In accordance with the present invention, an elongated surgical instrument holder for use during surgical procedures and during cleaning and storage of surgical instruments. The holder incudes a shelf adapted to receive an elongated surgical instrument, a restrainer means which compressively secures the instrument to the shelf, a lateral retainer which prevents lateral movement of the instrument on the shelf, and a bracket supporting said shelf. The invention additionally includes at least one protruding post outstanding from the shelf and extending through a hole or ring in the instrument which additionally secures and prevents movement of the instrument when secured by the invention. Additionally, when used in combination with an existing surgical instrument case, or when otherwise desired, the bracket may be pivotally secured to an ex isting base and provided with a locking means to allow selective foldable-collapsibility of the invention. Furthermore, the holder may have a teflon coating to withstand the corrosive character of an ultrasonic cleaning solution; thereby providing for use of the holder in combination with that cleaning method. Alternately, the holder may be used as an instrument holding means during a surgical procedure.

BRIEF DESCRIPTION OF THE DRAWINGS The invention is illustrated in the accompanying drawing wherein:

FIG. 1 is a perspective view of the preferred embodiment of the holder of the invention showing it pivotally supported in a raised position on an existing base, and provided with a locking means to allow selective foldable-collapsibility of the holder.

FIG. 2 is a plan view of the preferred embodiment of the holder in a raised position showing it removablysecuring a pincer-like surgical instrument having two elongated members pivotally joined in a partially opened position.

FIG. 3 is an elevational view of the preferred embodiment of the holder in a raised position showing it removably-securing a pincer-like surgical instrument having two elongated members pivotally joined shown in FIG. 2.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A holder in accordance with the invention is illustrated in FIGS. 1 through 3 and is generally indicated by reference character 10. The holder includes a shelf 11 supported by a frame or bracket 22 which is pivotally secured to an existing base or similar surface 26 by

pivotal means

27 and 28. The shelf 1 l is rigidly affixed to the bracket 22 by welding or other well known means at

points

20 and 21. Shelf 11 is secured to the bracket 22 in a manner whereby the surface of the shelf 11 is substantially parallel to the pivotal axis 42. The invention additionally provides for a plurality of

shelves

37 and 38, although not limited thereto, which are substantially parallel to shelf 11 and are rigidly affixed to the bracket 22 in the same manner as shelf 11 at 35 and 36, and 24 and 25, respectively.

FIG. 1 shows a restrainer 12 disposed laterally parallel to the plane of the shelf 11. The restrainer l2 and the shelf 11 may be of one-piece construction as set out in the preferred embodiment, or in an alternate form, the restrainer 12 may be a separate component welded or otherwise secured to the structure of the invention to position it laterally parallel to shelf 11.

A spring means, shown at 15 and 19, is included in the invention to facilitate and insure lateral resiliance in the restrainer. By this means, when an instrument is to be held by the holder of the invention, it can be inserted longitudinally above and across the outer end 16 of the shelf 11 and thereafter emplaced on said shelf,

while being disposed between said shelf and restrainer. Because the restrainer 12 is forceably deflected away from the adjacent parallel shelf 11 when an instrument is inserted therebetween, the instrument is compressively secured between the shelf 11 and the adjacent parallel restrainer 12.

As particularly shown in FIGS. 2 and 3, which additionally show pincer-type surgical instruments having two elongated members pivotally joined held by the holder, the invention includes a lateral retainer and a finger-gripping-ring securing means for each shelf of the invention. As hereinbefore set out, the lateral retainer prevents lateral movement of the instrument on the shelf 1 1. In the preferred embodiment of the invention it includes retaining ridges l3 and 17 disposed on either side of the outer end 16 of the shelf 11 to thereby arrest lateral movement of an instrument held by the invention.

The finger-gripping-ring securing means consists of posts formed of a to protrude in the wire on each side of the shelf 11 and, outstanding from the shelf 11 protrude and extend through a finger-gripping-ring on each handle of pincer-type surgical instruments held by the holder, or as shown at location 44 in FIG. 3, the manner in which the instrument is secured is illustrated by, one post which can be seen extending through a cut away portion of a ring on one handle of an instrument. This feature provides means for securing an instrument in the holder; and, when taken in conjunction with the lateral retainer, provides a means of securing pincerlike surgical instruments in a partially opened position to facilitate cleaning of the instruments when held by the invention as hereafter described.

As illustrated in FIG. 2, the pincer-like surgical instrument held by the holder of the invention is secured on the shelf 11 in a partially opened position. By securing the instrument in this manner, the cutout portions 34 in both elongated members of the instrument are exposed sufficiently to facilitate, cleaning of foreign matter from the instrument without removing it from the holder. Consequently, the holder can be used to secure and hold surgical instruments during cleaning and sterilizing procedures thereby minimizing the possibility of structural damage and bacteriological contamination resulting from handling by medical personnel prior and subsequent to use in a surgical procedure. More specifically, when the invention is used in conjunction with an immersible fluid cleaner such as the ultrasonic cleaner disclosed in Peterson, US. Pat. No. 3,640,295, it is unnecessary to ever remove the surgical instrument from the holder except at the times it is actually used in the procedure; whereafter, the instrument is immediately returned and resecured in the holder.

The preferred embodiment of the invention additionally provides for the bracket 22, carrying the shelf 11, to be pivotally supported on an existing base 26 or similar surface. This particular feature provides for the selective foldable-collapsibility of the invention whereby the bracket 22 may be positioned in an outstanding position as shown in FIG. 1 for use during a surgical procedure, and rotated about the pivotal axis 42 as illustrated by line 32 to a collapsed position for cleaning and subsequent storage. Additionally, to hold the bracket in the outstanding or collapsed position, locking means is provided in the invention such as the snapclips shown at 29 and 31 in the drawings. As set out above, it should be particularly noted that the bracket 22 may be rotated and locked in either the outstanding or collapsed position when instruments are removablysecured by the holder.

This feature thereby effectively alters the outside dimensions and shape of the holder; thereby providing for improved utilization of cleaning devices such as an ultrasonic cleaner by facilitating the use of the holder with that type of cleaner, as well as the number of holders utilized during a particular cleaning cycle.

Turning now to consideration of the fabrication of the preferred embodiment, as well as the material utilized therein, the shelf 11, restrainer 12,

lateral retain ers

13 and 17, and finger gripping ring securing means 14 and 18 are of one piece wire construction. Similarly, the bracket 22 is fabricated from one length of wire. In assembling the invention, after forming the two appropriate lengths of wire into their respective shapes, the wires may be welded one to the other as illustrated at

points

20 and 21; whereafter the bracket 22 is pivotally secured to an existing base to complete the assembly. This particular structure, in addition to providing an economic and simplified manner of construction, also provides a means whereby ultrasonic waves may adequately penetrate the holder to facilitate instrument cleaning when the holder is immersed in an ultrasonic cleaning bath.

Factors affecting the type of material used in the preferred embodiment of the invention include the final uses to which the holder will be put. For ordinary uses it may be of plastic or the like. In uses involving ultrasonic cleaning, because of the particularly corrosive character of ultrasonic cleaning baths, it should be constructed of or coated with a material which is substantially unaffected by repeated immersion in the ultrasonic cleaning bath. Polytetrafluoroethylene, referred to by the trademark Teflon, is one material which has been found to meet this requirement; therefor, the preferred embodiment provides a Teflon coating for the shelf ll, restrainer l2, lateral retainers l3 and 17, and finger gripping ring securing means 14 and 18, although not restricted thereto.

Although the invention has been described and illustrated with a certain degree of particularity, it is understood that the present disclosure has been made only by way of example and that numerous changes in the details of construction and the combination and agreement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
