Abstract
A medical instrument tool or end effector constructed of a fixed jaw having a distal grasping end and a proximal body end; a movable jaw having a distal grasping end and a proximal body end; a slide member controlled from a tool actuator, adapted for linear translation and supported between the jaws; at least one link that inter-couples between the slide member and the movable jaw; and a pivot member mounted at the fixed jaw and for engagement with a slot in the body end of the movable jaw.
Claims22
A medical instrument tool or end effector that has a longitudinal axis and that is comprised of:
- a fixed jaw having a distal grasping end and a proximal body end;
- a movable jaw having a distal grasping end and a proximal body end that includes an elongated slot;
- a slide member controlled from a tool actuator, adapted for linear translation and supported between the jaws;
- a pair of links that inter-couple between the slide member and the movable jaw;
- each link having opposed end support pins constructed and arranged to have the links disposed in a parallel and spaced apart relationship when the jaws are in a closed position;
- and a pivot member mounted at the fixed jaw and for engagement with the elongated slot in the body end of the movable jaw.
A medical instrument tool or end effector that is comprised of:
- a fixed jaw having a distal grasping end and a proximal body end;
- a movable jaw having a distal grasping end and a proximal body end;
- a slide member controlled from a tool actuator, adapted for linear translation and supported between the jaws;
- at least one link that inter-couples between the slide member and the movable jaw;
- and a pivot member mounted at the fixed jaw and for engagement with a slot in the body end of the movable jaw;
- wherein the slide member comprises a yoke including, a body end connected with a tool actuation cable and a pair of spaced apart arms;
- wherein said pair of arms include a set of upper arms and a contiguous set of lower arms;
- and an angled transition section between sets of upper and lower arms.
A medical instrument tool or end effector that has a longitudinal axis and that is comprised of:
- a first jaw having a distal grasping end, a proximal body end and a slot that extends in the direction of the longitudinal axis;
- a second jaw having a distal grasping end and a proximal body end;
- a slide member controlled from a tool actuator, adapted for linear translation and supported between the jaws, and including a slot;
- at least one link that inter-couples between the slide member and the second jaw;
- and a pivot member mounted at the first jaw and for engagement through the slot in the slide member to the second jaw;
- said at least one link having a lower pivot pin that is constructed and arranged to engage with the slide member and extend into the slot in the first jaw.
A medical instrument tool or end effector that has a longitudinal axis and that is comprised of:
- a fixed jaw having a distal grasping end, a proximal body end;
- a movable jaw having a distal grasping end a proximal body end and a slot;
- a slide member controlled from a tool actuator, adapted for linear translation and supported between the jaws;
- at least two links that inter-couple between the slide member and the movable jaw;
- and a pin member for engagement through the slot in the movable jaw;
- said at least two links having lower pivot pins that are constructed and arranged to engage with the slide member.
