ABSTRACT:
The systems described herein include a surgical instrument having an elongate shaft member, a slide mounted thereon, a handle with two legs, a disengagement mechanism permitting the mounted slide to be removed from the elongate shaft member, and a lock mechanism preventing slide disengagement. In one embodiment, the handle comprises a first and a second handle leg, the second handle leg pivotable around the first handle leg, and the second handle leg having a proximal end bearing an axially directed slot that permits engagement with a cross-pin. In this embodiment, maximal spreading of the two handle legs inclines the slot in the proximal end of the second handle leg in a proximal direction, permitting the disengagement of the crosspin from the slot when the slide is retracted to its most proximal position. One embodiment of the apparatus described herein includes a lock mechanism comprising a mechanical stop that is capable of limiting the rotation of the second handle leg into a maximally spread position.
