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.

[ What is claimed is:] [1.] Surgical instrument comprising:an elongate shaft member with no joints and having a distal end and a proximal end;a first handle leg connected to the proximal end of the shaft member;a second handle leg mounted pivotably relative to the first handle leg, wherein the second handle leg can be spread apart from or approximated to the first handle leg by pivoting said second handle leg on a pivot mechanism to the first handle leg, said pivot mechanism comprising an axially directed slot positioned in an end portion of the second handle leg and a cross pin capable of being received in the slot, wherein with maximal spreading of the first and the second handle legs the slot is inclined in a proximal displacement direction of a slide and the cross pin allows axial displacement of the slide into a fully retracted position on the proximal end of the shaft member;said slide being axially displaceable on the shaft, and said slide being capable of being articulated with the second handle leg and capable of being removed from the shaft member when displaced to the fully retracted position on the proximal end of the shaft member;a sliding path on the shaft member along which the axial displacement of the slide on the shaft member is guided; anda releasable lock capable of limiting pivoting of the second handle leg into a maximally spread position, wherein the releasable lock comprises a mechanical stop element.
