Abstract

Abstract A surgical instrument rack useful for holding, carrying, organizing, and counting a plurality of ringhandled surgical instruments. The rack is formed of autoclavable polymeric material and includes two movable or separable members which coact with each other and with the surgical instruments to secure such instruments against release in parallel side-by-side relation with the handles and jaws (or blades) of such instruments separated slightly to facilitate sterilization of their surfaces. The structural relationship of parts responsible for the retention and automatic camming of the instruments into such slightly open positions is disclosed.

Claim 12
Dependent Claim 16 words
The rack of claim 1 in which said partitions are formed integrally with said upstanding wall.
Claim 13
Dependent Claim 71 words

Claim 14
Dependent Claim 61 words
The rack of claim 1 in which said support member is provided with a second upstanding wall parallel to and spaced in front of the first-mentioned upstanding wall, said second wall having an upper edge engagable with the handles of at least some instruments supportable by said support member to hold the jaws of said instruments slightly above said flat surface.
Claim 15
Dependent Claim 22 words
The rack of claim 13 in which said partitions are arcuate and bridge the upper edges of said first and second walls.
Claim 16
