Abstract:
1. A working end of a medical device, the working end comprising: a jaw assembly defining opposing jaw portions moveable between an open position and a closed position relative to an axis; at least one jaw defining a proximal cam surface portion and a distal cam surface portion, the cam surface portions being proximal and distal respectively to a rotation point of the at least one jaw in open and closed positions; an axially reciprocatable member carried by the working end, the reciprocatable member having spaced apart first and second cam surfaces for engaging said proximal and distal cam surface portions of said at least one jaw, respectively; wherein extension of said reciprocatable member causes said second cam surface to slidably engage the distal cam surface portion of the at least one jaw to move the jaw assembly toward the closed position; and wherein retraction of said reciprocatable member causes said first cam surface to slidably engage the proximal cam surface portion of the at least one jaw to move the jaw assembly toward the open position wherein both jaw portions define an axially-extending channel for slidably receiving a transverse element of the reciprocatable member.
