Abstract

The present application discloses instruments for use in an endoscopic discetomy procedure which are configured to be disassembled for cleaning and reassembled for subsequent utilization. The preferred embodimens include endoscopic rongeur-style instruments which may be used to remove calcification, to trim away part of a bone and to remove tissue and tissue samples for biopsy purposes. The endoscopic surgical instruments of the present application are provided with a handle mechanism , an elongated endoscopic portion extending from the handle mechanism and a tool mechanism supported at a distal end of the endoscopic portion . The handle mechanism includes a body portion having an upper and a lower body portion, a stationary grip extending from the body portion and a pivotable grip pivotally mounted to body portion. In one embodiment, the pivotable grip is detachably mounted to body portion by a locking member which includes a fastener having a rod and an abutment portion. The endoscopic portion includes a first half-- section member and a second half-section member which is preferably removably mounted to the first half-section member and is slidable with respect thereto.
