Abstract: An instrument that includes an outer member, an inner member, and a jaw assembly. The inner member includes a first arm and a second arm. The jaw assembly includes a first jaw and a second jaw. The first jaw is connected to the first arm at a first pivot joint and to the outer member at a second pivot joint. The second jaw is connected to the second arm at a third pivot joint and to the outer member at a fourth pivot joint. The inner member is adapted to be moved distally relative to the outer member so that the first jaw pivots about the second pivot joint towards the second jaw and the second jaw pivots about the fourth pivot joint towards the first jaw thus moving the jaw assembly from the open position towards the closed position.

IPC: A61B18/14

Abstract: An electrosurgical device comprising: (a) a stylet including: (i) a first jaw; (ii) a second jaw that is movable relative to the first jaw from a first position where the first jaw and the second jaw are open to a second position where the first jaw and the second jaw move towards each other to grasp tissue therebetween; and (iii) one or more jaw support rods connected to the first jaw, the second jaw, or both; and (b) a housing connected to the stylet and the stylet extending from the housing, the housing including: (i) an operable mechanism including: (1) a fourth link; (2) a second link; (3) a first link being connected to the fourth link via a first pivot and being rotatable relative to the first pivot, and connected to the second link at a second pivot so that movement of the first link moves the second link relative to the fourth link; and (4) a third link being connected to the second link at a third pivot so that movement of the second link moves the third link, and the fourth link being connected to the third link at a fourth pivot, the third link moving about the fourth pivot to move the one or more jaw supports so that the first jaw and the second jaw are moved between the first position and the second position; and wherein the fourth link is the housing and the first link is a clamp lever that extends outside of the housing and is actuated by a user.
