Abstract
A biopsy forceps device is presented herein wherein an elongated flexible hollow body portion having a lumen extending therethrough is provided with proximal and distal ends. A forceps assembly is coupled to the distal end of the body portion and the assembly includes a pair of forceps. A control wire having proximal and distal ends extends through the lumen of the body portion and is coupled at its proximal end to a handle and at its distal end to a forceps assembly. A trigger is mounted to the handle for slidable movement relative thereto between a proximal position and a distal position. A gripping device grips the proximal end of the control wire and is movable between first and second positions for respectively moving the control wire between a forceps open condition and a forceps closed condition. The gripping device is resiliently biased toward its first position. The lever arm engages and moves the gripping device from its first position to its second position against the resilient forces. A releasable locking mechanism is carried by the trigger and the lever arm to lock the gripping device in the forceps closed condition so long as the trigger is in its distal position.
