An endoscopic biopsy forceps has a detachable proximal handle portion and a distal portion which includes a pair of jaws mounted at the distal end of a flexible conduit. At least one pull wire extends through the conduit and is coupled to the jaws so that movement of the pull wire(s) through the conduit causes the jaws to open and close. The proximal end of the pull wire(s) is provided with a mating tip and the proximal end of the conduit is provided with a mating sleeve. The handle portion includes a shaft and a spool. The conduit is detachably attached to the shaft, while the pull wire(s) is detachably attached to the spool. Attachment is effected by spring biased coupling devices which engage the mating tip of the pull wire(s) and the mating sleeve of the conduit.

An endoscopic biopsy forceps comprising: a) a flexible conduit having a proximal and a distal end, said proximal end of said conduit being provided with a first mating means for mating with a coupling means; b) a pair of jaws mounted at the distal end of said flexible conduit; c) at least one pull wire having a proximal and a distal end, the distal end of said pull wire being coupled to said pair of jaws, said pull wire extending through said conduit and said proximal end of said pull wire extending beyond said proximal end of said conduit, movement of said pull wire through said conduit effecting opening and closing of said jaws, said proximal end of said pull wire being provided with a second mating means for mating with a coupling means; d) a handle having first coupling means for detachably attaching to said first mating means, and second coupling means for detachably attaching to said second mating means, handle including actuating means for moving said pull wire through said conduit, wherein, one of said first mating means and said first coupling means is spring biased, and one of said second mating means and said second coupling means is spring biased, such that insertion of said proximal end of said flexible conduit and said proximal end of said pull wire into said handle automatically couples said first mating means to said first coupling means and said second mating means is automatically coupled to said second coupling means upon one of said insertion and movement of said actuation means.
