Abstract

An instrument cassette includes a first container portion having a first plate which defines a first substantially planar interior surface, wherein the first planar interior surface defines an interior surface line L.sub.1. The instrument cassette also includes a second container portion having a second plate which defines a second substantially planar interior surface, wherein (i) the second planar interior surface defines an interior surface line L.sub.2, and (ii) the second container portion is positioned relative to the first container portion so that an interior space is defined therebetween. The instrument cassette further includes a positioning member formed in the first plate, wherein (i) the positioning member includes a first positioning segment which extends immediately outwardly from the first planar interior surface in a direction away from the interior surface line L.sub.1, (ii) the positioning member further includes a second positioning segment which extends inwardly from the first positioning segment in a direction toward the interior surface line L.sub.1, and (iii) no portion of the first positioning segment or the second positioning segment extends into the interior space across the interior surface line L.sub.1. The instrument cassette also includes a locating member formed in the second plate, wherein (i) the locating member includes a first locating segment which extends immediately outwardly from the second planar interior surface in a direction away from the interior surface line L.sub.2, (ii) the locating member further includes a second locating segment which extends from the first locating segment, and (iii) no portion of the first locating segment or the second locating segment extends into the interior space across the interior surface line L.sub.2. An associated instrument cassette assembly is also disclosed.
