A container and a method of using the container for storing sheets of material, such as photosensitive materials, enables individual sheets to be transported from the container to an imaging unit by a feed mechanism of the imaging unit. The container fits within the imaging unit to provide a light-tight environment for the photosensitive material. The container includes shiftable walls, including a front ramp which can have a serrated surface to separate sheets. The container also includes a clamping components to allow for the removal of a light-tight bag which encloses the sheets.

A trocar for placement in the lumen of a cannula to facilitate inserting the cannula through tissue is disclosed. The trocar has an improved trigger/obturator assembly wherein the trigger comprises tissue cam parts each having (a) planar outer surfaces, and (b) an arcuate end portion at the distal end of the trigger including a distal edge surface that is arcuate about an axis normal to the outer surfaces. The arcuate end portions intersect at edge surfaces which are obscured by the arcuate end portions.

A kit assembly for use during a laparoscopic surgical procedure. The kit assembly may have a plurality of cannula or a plurality of trocar assemblies. The kit assembly affords the convenient use of different types of trocar or cannula assemblies during a laparoscopic surgical procedure.

Kit assembly for use during a laparoscopic surgical procedure

A kit assembly for use to construct a desired trocar obturator used during a surgical procedure is disclosed. The kit includes a proximal portion of the obturator and a plurality of different distal end portions. The proximal portion may be releasably attached to a distal portion by virtue of a detent mechanism. Reuse of the proximal portion affords potential cost savings. The plurality of distal end portions affords the surgeon a choice between different trocar tips so that the trocar may be customized for a particularly surgical procedure.
