Abstract

Abstract An endoscopic biopsy forceps instrument includes a distal jaws assembly detachable from a proximal handle assembly. The proximal handle assembly includes a centrally slotted shaft and a spool having a laterally seated cross block which passes through the central slot. The distal jaws assembly includes jaws mounted on a clevis at the distal end of a coil and coupled to a pull wire which extends through the coil to its proximal end. The proximal end of the coil is provided with a connecting sleeve provided with a frustoconical portion having double-helical threads for removably coupling the coil to a shaft having a distal frustoconical portion having double-helical threads. The proximal end of the pull wire is provided with a grooved mating member and the spool is provided with a locking assembly having a spring-biased push button latch for releasably engaging the grooved mating member. The grooved mating member has an elongate cylindrical distal portion, a central cylindrical portion having a relatively larger diameter, a proximal cylindrical grooved portion, and a proximal conical portion having a rounded apex. The elongate distal portion has a bore into which the pull wire is secured. The mating member end of the pull wire can be snapped into the locking assembly and the coil can be quickly and securely coupled to the shaft.
