Description

A SYSTEM FOR SECURING MEDICAL TOOLS FOR STERILIZATION The present invention relates generally to a system for organizing and securing medical tools or instruments during a sterilization procedure. More particularly, the subject invention pertains to a medical tool or instrument holding system which is designed to universally secure and hold a variety of different medical or surgical tools or instruments required for a particular medical or surgical procedure during sterilization, while also reducing the likelihood of costly damage to the variety of different medical tools and instruments.

The art of sterilization of medical tools and instruments has proceeded through several evolutions over the last several decades as diseases such as AIDS, hepatitis-B, and other communicable diseases have become of increased concern.

Disposable medical and surgical tools and instruments have been developed, but are very expensive, and are also generally not of as high quality as nondisposable medical tools and instruments. Accordingly, procedures and devices which allow a sterilization procedure to be performed on nondisposable medical tools and instruments have been of increasing interest in this art.

Sterilization procedures for medical tools and instruments generally utilize either a thermal enclave which heats the tools and instruments with steam above a specific temperature, or treats the medical tools and instruments with sterilizing ethylene oxide gas or with sterilizing ozone. Such sterilization procedures often employ a case or tray which is designed to hold and organize all of the medical tools which are required for a particular medical or surgical procedure. Each case or tray is frequently custom designed to organize and securely hold a particular set of medical tools and instruments which are required for a particular medical or surgical procedure. With this approach, each different particular medical procedure requires a separate case which is custom designed to organize and securely hold the particular set of medical tools and instruments required for that particular medical or surgical procedure.

In general, a generic type of sterilization tray or basket as provided by the prior art has suffered from a disadvantage in that particular medical tools and instruments may not be precisely secured therein, which can sometimes result in physical damage to imprecisely mounted, delicate medical tools or instruments. In general, the design of a generic sterilization case or tray as provided by the prior art has been somewhat fixed, which does not allow a medical doctor or technician a great deal of latitude to reposition the supports therein to provide a more custom fit for a particular set of medical tools or instruments required for a particular medical procedure.

Custom sterilization cases have frequently been constructed of hard coated aluminum to minimize the weight of the unit, as the unit is frequently handled by medical technicians of slight stature. These cases may be equipped with trays which are frequently constructed of durable surgical grade stainless steel. Sterilization cases or trays of the prior art have sometimes been constructed of a first piece of sheet metal perforated with an array of holes which is separated from a second piece of sheet metal also perforated with a second array of holes, which are offset with respect to the first array of holes. A sterile filter is positioned between the first and second pieces of perforated sheet metal. A sterilization case constructed in this manner can be sterilized in an enclave, and then the contents of the sterilization case remains sterilized for several months.

Another approach pursued by the prior art is to sterilize the tools in a basket and then hand or custom wrap each particular medical tool or instrument required for a particular medical procedure. This approach suffers from a disadvantage of requiring each particular tool or group of instruments to be hand wrapped, which add expense and presents additional sterilization problems.

The prior art has also provided a sterilization case which can contain multiple stacked trays therein. The cases have been fitted with soft silicone fingers or silicone scalloped cradles designed to securely hold the medical instruments or tools therein to protect them against accidental damage, or can be coated with a soft material such as silicon rubber to protect delicate instrument tips against metal to metal contact. Prior art sterilization cases and trays have been designed to organize and securely hold a wide variety of medical and surgical instruments and tools such as scopes and cameras, straights, cannulae, picks, obturators, trochars, offset instrumentation, forceps, etc., and accordingly have been designed in a wide variety of sizes and shapes, with many expensive pins, clamps and dividers.

Accordingly, the present invention is directed to a new design for a medical or surgical tool or instrument holding system which solves problems with respect to instrument organization and protection. Moreover, rigid container users may customize their cases to provide the protective advantages normally associated with a custom tray. The medical or surgical holding system of the present invention holds medical tools and instruments securely at selected angles in container baskets and reduces the likelihood of costly damage to delicate instruments, while eliminating many of the expensive pins, clamps and dividers provided in the prior art. A variety of configurations provides virtually unlimited customizability of sets. The medical or surgical holding system of the subject invention is easy to use, and also provides for secure opening and closing. A preferred embodiment is manufactured of durable stainless steel and silicone Ultrasoft™ spike strips and cradles for long life and extra protection.

The medical surgical holding system of the present invention also allows safe covered removal of soiled tools or instruments to the decontamination department, and side handles and a lid handle facilitate easy and ergonomic use. A soaking pan/basket combination helps meet OSHA requirements in the OR and CS by eliminating the need to reach into an unclear cleaning/disinfection solution where sharp instruments may be present. A wide assortment of sizes allow a stand-alone soaking pan to be used with current standard size trays and container baskets when utilized with optional lifting handles. Surgical grade stainless steel construction makes the surgical holding device of the present invention more durable and easier to clean than plastic or aluminum.

In accordance with the teachings herein, the present invention provides a system for securing small medical or surgical tools or instruments for sterilization. The system includes a perforate carrier for supporting a plurality of tools and brackets during sterilization, while also providing for free transmission of a sterilization media such as steam or ethylene oxide. At least one removable bracket member is removably mounted on the perforate carrier, and is selectively positionable thereon for the selective orientation of tools.

An upper support member is releasably secured to the lower support member, and includes a second resilient member which extends downwardly from the upper support member, with the upper support member having a first engaged position and a second disengaged position. The arrangement is such that the first and second resilient members cooperate to secure the medical or surgical tools or instruments therebetween when the upper bracket is in its engaged position. In different embodiments, the perforate carrier can be a stainless steel tray, a sterilization container, or a stainless steel tray within a sterilization container. In greater detail, one of the resilient members may be formed of a resilient mat having a multiplicity of fingers of soft silicon rubber, with the rubber fingers having a durometer of less than 40. In one designed embodiment, the resilient fingers are conical and spaced on one-fourth inch centers to define free spaces therebetween. The upper support member is secured by a hinge to the lower support member at one end thereof. The upper support member also includes a resilient detent for releasably securing it to the lower support member in the engaged position. The opposing resilient member is a hold down bar formed of silicon rubber having a durometer of 40 to 80. The opposing resilient member has a V-shaped tool engaging flange, which is secured to one of the support members along its apex to provide a bifurcated tool engaging surface. The opposing resilient member defines tool engaging openings formed therein, such as a plurality of arcuate scallops along its tool engaging surface. The lower support member is L-shaped with a linear member having first and second ends for engaging the perforate cover, and at least one upstanding flange formed at the second end thereof. The upper support member has a linear dimension complementary to that of the lower support member and first and second downwardly extending flanges formed at the ends thereof which engage the lower support member. The first downwardly extending flange on the upper support member is hinged to the first end of the lower support member. The second downwardly extending flange overlies the upstanding flange when in the engaged position, and is secured thereto by a detent. The detent can be formed by a pair of dimples, with a first dimple formed in the upstanding flange and the second dimple formed in the downwardly extending flange such that the dimples engage one another in the second position.

A second upper support member can also be provided which is pivotably attached to the upper support member at one end thereof, with the upper support member and the second support member each defining resilient tool engaging surfaces therebetween to provide for the retention of a second plurality of tools above the first plurality of tools.

The present invention also provides a system for securing small medical tools and implements for sterilization, in which a perforate carrier is provided for supporting a plurality of tools and brackets during sterilization, which is designed to provide for the free transmission of a sterilization media such as steam or ethylene oxide. At least one removable bracket member is removably mounted on the carrier, and is selectively positionable with respect thereto for the selective orientation of tools. The bracket member has a lower support member releasably secured to the perforate cover for selective positioning with respect thereto. The lower support member is vertically spaced from the perforate carrier, and defines a plurality of openings for receiving a plurality of related tools or implements. An upper support member is releasably secured to the lower support member, and is provided with a resilient mat which extends downwardly from the upper support member, which is provided with a first engaged position and a second disengaged position. The lower support member and the resilient mat cooperate to restrain the plurality of related medical tools or implements within the plurality of openings. The mat is preferably formed with a plurality of soft resilient fingers of silicon rubber having a durometer of less than 40. The upper support member is pivotally mounted to the lower support member at one end thereof, and is releasably secured at the second end thereof to provide the first engaged and second disengaged positions.

Referring to the drawings in detail, Figure 1 is a front and top perspective view of an exemplary embodiment of a system 10 for securing medical tools 12 for sterilization constructed pursuant to the teachings of the present invention. The system 10 includes a carrier 14 having an array of perforated holes 16 for supporting a plurality of tools 12 in brackets 18, 18 during sterilization, while also providing for the free transmission of a sterilization media such as steam or ethylene oxide through the perforation holes 16. At least one and preferably two removable bracket members 18 are removably mounted on the perforate carrier 14, such as by bolts 21, Figure 4, extending through selected perforation holes 16, such that each bracket member 18, 18 is selectively positionable thereon for the selective orientation of medical tools.

As illustrated in Figure 2, the bracket member 18 is provided with a lower support member 20 removably mounted on the perforate carrier for selective positioning with respect thereto. A first resilient member 22 extends upwardly from the lower support member 20. An upper support member 24 is releasably secured to the lower support member 20, and includes a second resilient member 26 which extends downwardly from the upper support member 24, with the upper support member having a first engaged position, as shown in Figure 1, and a second disengaged position, as shown in Figure 2. The arrangement is such that the first and second resilient members 22, 26 cooperate to secure the medical or surgical tools or instruments 12 therebetween when the upper bracket is in its engaged position, as shown in Figure 1.

In different embodiments, the perforate carrier 14 can be a stainless steel tray, or can be a sterilization container. The upper support member 24 is secured by a hinge 30 to the lower support member 20 at one end thereof. The upper support member also includes a resilient detent 32 for releasably securing it to a second resilient detent 34 in the lower support member in the engaged position.

In greater detail, at least one of the resilient members, the lower 22 in Figure 2, is formed of a resilient mat having a multiplicity of fingers 28 of soft silicon rubber, with the rubber fingers 28 having a durometer of less than 40. In one designed embodiment, the resilient fingers are frusto-conical, as illustrated in Figure 2, and are spaced on one-fourth inch centers to define free spaces therebetween. The opposing top resilient member 26 is a hold down bar formed of silicon rubber having a durometer of 40 to 80. The opposing resilient member 26 has a V-shaped tool engaging flange, shown in phantom to the left of Figure 2, which is secured to the top support member 24 along its apex 36 to provide two bifurcated tool engaging surfaces at the open ends of the V.

Figure 3 is a front elevational view of a second embodiment of a removable bracket member 40 which is similar in construction to that of Figure 2 but which includes two lower resilient supports 42, each of which includes an open notched top at 44 to receive a shaft of a medical tool. Figure 4 illustrates a sectional view along arrows 4-4 in Figure 3 of the second embodiment of the removable bracket member, and illustrates a top V- shaped bifurcated resilient support member 46 similar to that of Figure 2, which is mounted in a mounting 48 secured to the upper support member 24. Figure 5 is a front elevational view of a third embodiment of a removable bracket member 50 which is also similar in construction to that of Figures 2-4 but which includes two lower resilient supports 52, each of which is formed on a common base 54 and each of which defines tool engaging openings 56 formed therein, such as a plurality of arcuate scallops 56 along its tool engaging surface. Figure 6 illustrates a sectional view along arrows 6-6 in Figure 5 of the third embodiment of the removable bracket member, and illustrates a top V- shaped bifurcated resilient support member 46 similar to that of Figure 4, which is mounted in a mounting 48 secured to the upper support member 24.

Figure 7 is a front elevational view of a fourth embodiment of a removable bracket member 60. Figure 8 illustrates a sectional view along arrows 8-8 in Figure 7 of the fourth embodiment of the removable bracket member, and illustrates a top support member 61 pivoted to a bottom support member 62 by a hinge 64 and having matching detents 66 to provide for a secure closure of the top and bottom support members. The upper surface 68 of the bottom support member 62 provides a plurality of tool engaging openings 70 for supporting various tools 72 and various fastening screws 74 therein. The top support member 61 provides a depending resilient member 76 similar in construction to the resilient member 22 of Figure 2. Figure 9 is an isometric illustration of a sterilization case 80 constructed of hard coat anodized aluminum having a sealing gasket 82 and a pair of handles, one of which is illustrated at 84. The upper half of the case has been omitted for the purposes of illustration but is complementary to and secured to lower half by means of latches at either end, one of which is illustrated at 86. The sterilization case has a plurality of openings defined in a planar bottom wall (not shown). Removably fitted on the inside of the case is a filter plate 88 which also has a plurality of holes formed therein. The holes in the filter plate 88 are offset from the holes defined by the sterilization case 80. Positioned between them is a sterile filter 90, only the edge of which is visible, which is opaque to bacteria and viruses, but transmissive to gases such as steam and ethylene oxide which are used as the sterilization media. A removable tray 92, similar to carrier 14 of Figure 1, is sized to fit snugly within the sterilization case 80. While a single tray has been illustrated in Figure 9, it is noted that multiple trays, or a tray and a basket may be used as desired, in order to accommodate the number of tools or instruments required for any given medical or dental procedure. The stainless steel tray 92 is constructed of perforate stainless steel surrounded by a reinforcing band 94 which may be equipped with handles 96 to facilitate removal from the sterilization case. Alternately, tray 92 may be formed of stainless steel wire mesh, and may be equipped with upwardly extending side rails to support a second stainless steel tray to be fitted within the sterilization container. As was previously described with respect to

Figure 1, stainless steel tray 92 is fitted, for illustrative purposes only, with a pair of removable bracket members 18, 18 which secure tools 12 for sterilization. Tray 92 also is equipped with a second pair of brackets 98 and 100 which have been attached to secure medical implements 102 and 104 in their desired position.

One of the advantages of the present invention is the ability to reuse the sterilization case 80 and the accompanying tray 92 in the event the instruments or tools for the medical or dental procedure are changed. The use of the removable and positionable brackets 18, 18, 90, and 100 enable one to reconfigure the arrangement as desired, thus providing a system which is adaptable to a wide variety of needs and configurations. Figure 10 illustrates a dual bracket 110 configured to arranged first and second layers of tools above one another. As illustrated in Figure 10, a U-shaped stainless steel lower support member 112 is provided which may be releasably secured to said perforate carrier for selective positioning with respect thereto. The U-shaped bracket has a pair of upstanding flanges 114 and 116 which extend upwardly from the carrier. A hinge 118 is mounted at the upper most periphery of upstanding flange 116. Secured to the hinge is a second U-shaped intermediate support member 120 which is pivotably mounted with respect to the lower support member by means of hinge 118. The intermediate support member 120 is also equipped with a pair of upstanding flanges 122 and 124 which are generally aligned with the upstanding flanges 116 and 114 formed on the lower support member. A hinge member 126 is attached to the upper most portion of flange 122, and secures thereto, an L-shaped upper support member 128 having a single downwardly extending flange 130. As illustrated in Figure 10, the upper support member may be pivoted in the direction of arrow A from a first engaged position to a second disengaged position as illustrated in Figure 10. When in the engaged position, dimples 134 and 136 engage complementary dimples 138 and 140 formed on upstanding flanges 114 and 124. The dimples 134 through 140 provide a resilient gripping means which releasably secure the upper support member to the intermediate and lower support member in their first engaged position.

As illustrated in Figure 10, the double bracket is equipped with a plurality of resilient means for positioning and holding medical or dental tools. A mat of ultra-soft rubber fingers 142 is provided on the lower support member, and a single linear resilient hold-down-bar 144 is attached to the underside of the intermediate support member 120. As was described previously with respect to Figure 2, the silicon rubber fingers 142 have a durometer of less than 40, while the single hold-down-bar 144 has a durometer of 40 to 80. Therefore, the hold-down-bar firmly engages and depresses any tools placed on the mat into resilient engagement with the mat and thus holds them in a secure manner.

A second mat of ultra-soft silicon fingers 146 is provided on the upper surface of the intermediate support member 120. It cooperates with a V-shaped bifurcated tool hold-down member 148 fitted to the underside of upper support member 128. It should be noted that any of the resilient members illustrated in Figures 3-8 could be used in either orientation in the dual bracket illustrated in Figure 10 in order to provide a truly customizable and reconfigurable system for securing small medical or dental tools. While Figure 10 illustrates the intermediate support member 120 in a first closed position, it should be understood that it may be pivoted upwardly in the direction of arrow A about hinge member 118 in a manner similar to that illustrated with respect to the upper support member 128. While several embodiments and variations of the present invention for a system for securing medical tools for sterilization are described in detail herein, it should be apparent that the disclosure and teachings of the present invention will suggest many alternative designed to those skilled in the art.
