Abstract
A biopsy forceps device is presented herein which employs a forceps assembly having a pair of forceps connected to the distal end of a control wire having its proximal end extending into a hub. A control wire actuator is connected to the proximal end of the control wire and the actuator is slidably mounted to the hub for slidable movement relative thereto between proximal and distal positions for respectively causing the forceps to be in a closed condition and in an open condition. A releasable locking mechanism normally blocks forward slidable movement of the actuator to prevent the forceps from being actuated to an open condition. A release mechanism releases the locking means from blocking forward movement of the actuator to thereby permit forward movement of the actuator causing the forceps to be actuated to an open condition.
