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.
