Abstract
Abstract A retainer and method of producing a retainer which cooperates with either a magnetic or non-magnetic surgical drape to hold instruments during surgical operations. A rectangular tray includes a wall which extends from the periphery of a base portion. The polypropylene base portion is thermally bonded to a thermoplastic rubber retainer to sandwich magnetic elements therebetween. The magnetic elements are magnetically attracted to a magnetic drape and thereby secure the retainer in any orientation with respect to the drape. The method including vacuum forming a thermoplastic shell over a tray configured mold to sandwich a magnetic element between the thermoplastic shell and a retainer.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
89 words
A system for retaining surgical instruments, comprising: a surgical instrument retainer including a base portion defined by a periphery; a wall projecting from said periphery wherein said wall terminates at a distance from said base portion; a flexible surgical drape; and a means for selectively securing said surgical instrument retainer to said surgical drape, said means comprising: a magnetic element incorporated in said base portion; and a plurality of magnets incorporated in said surgical drape such that a magnetic attraction exists between said magnetic element and said surgical drape.
Claim 2
Independent Claim
89 words
A system for retaining surgical instruments, comprising: a surgical instrument retainer including a base portion defined by a periphery; a wall projecting from said periphery wherein said wall terminates at a distance from said base portion; a flexible surgical drape; and a means for selectively securing said surgical instrument retainer to said surgical drape, said means comprising: a magnetic element incorporated in said base portion; and a plurality of magnets incorporated in said surgical drape such that a magnetic attraction exists between said magnetic element and said surgical drape.
Claim 3
Dependent Claim
28 words
The system for retaining surgical instruments of claim 1, wherein said magnetic element further comprises a material capable of producing a magnetic field external of said magnet element.
Claim 4
Independent Claim
91 words
A system for retaining surgical instruments, comprising: a surgical instrument retainer including: a back wall; and a front wall spaced from and opposed from said back wall, said spacing forming an aperture through which surgical instruments are passed; a flexible surgical drape; and a means for selectively securing said surgical instrument retainer to said surgical drape, said means comprising a magnetic element incorporated in said back wall and a plurality of magnets incorporated in said surgical drape such that a magnetic attraction exists between said magnetic element and said surgical drape.
Claim 5
Independent Claim
91 words
A system for retaining surgical instruments, comprising: a surgical instrument retainer including: a back wall; and a front wall spaced from and opposed from said back wall, said spacing forming an aperture through which surgical instruments are passed; a flexible surgical drape; and a means for selectively securing said surgical instrument retainer to said surgical drape, said means comprising a magnetic element incorporated in said back wall and a plurality of magnets incorporated in said surgical drape such that a magnetic attraction exists between said magnetic element and said surgical drape.
Claim 6
Dependent Claim
25 words
The system for retaining surgical instruments of claim 3, wherein said magnetic element is capable of producing a magnetic field external of said magnet element.
Claim 7
Dependent Claim
47 words
The system for retaining surgical instruments of claim 3, wherein a plurality of said magnetic elements are incorporated in said back wall so that said magnetic elements magnetically cooperate with said surgical drape independent of the orientation of said back wall with respect to said surgical drape.
