A surgical instrument includes a body, a pivotable trigger, and a ratcheting assembly. The ratcheting assembly may include a rotary ratchet coupled to the trigger and a pawl coupled to the body. The rotary ratchet may further include a ramp that disengages the ratchet from the pawl. A release feature may be included to selectively disengage a second member of the ratcheting assembly from a first member. In some versions, the release feature may include a rotation knob or a slidable handle. In another configuration, the ratcheting assembly may have a first member coupled to an actuator and a second member coupled to the body. The assembly may include a lock member coupled to the body that selectively engages a plurality of teeth disposed on the actuator. Alternatively, the assembly may include a pivotable pawl coupled to the actuator that engages one or more notches formed in the body. |
