Abstract

A clip applier tool comprising an elongate tubular member having a bore extending therethrough and having proximal and distal extremities. A push rod is slidably mounted in the bore and has proximal and distal extremities. An actuator is mounted in said bore in said tubular member. The actuator means is connected to the distal extremity of the push-pull rod. First and second clip applier jaw members are mounted in the bore in said tubular member and have proximal and distal extremities. A pivotal connection connects the proximal extremities of the jaw members to the distal extremity of the actuator.

Claims

1. A clip applier tool for applying a clip inside of a body in a laparoscopic surgical procedure comprising an elongate tubular member having a bore extending therethrough and having proximal and distal extremities, a push-pull rod slidably mounted in said bore and having proximal and distal extremities, actuator means mounted in said bore and having circumferential surfaces engaging the inside of the distal extremity of said tubular member for slidable movement therein, means connecting the actuator means to the distal extremity of the push-pull rod, first and second clip applier jaw members having elongate proximal extremities extending through said actuator means and having distal extremities adapted for gripping the clip and pivotal means connecting the proximal extremities of the Jaw members to said tubular member to permit the distal extremities of the jaw members to move between open and closed positions, each of the Jaw members being provided with a slot formed therein between the proximal and distal extremities thereof and pin means extending through the slots and coupled to the actuator means so that as the push-pull rod is actuated the pin means travels through the slots to cause the jaw members to move between open and closed positions with respect to each other, the actuator means engaging the jaw members distal of the slots to inhibit shifting of the distal extremities of the jaw members during application of the clip.

2. A tool as in claim 1 further including handle means coupled to the elongate tubular member and the push-pull rod for causing rectilinear movement of the push-pull rod with respect to the elongate tubular member.

3. A tool as in claim 2 further including means carried by the elongate tubular member and the handle means for permitting rotational movement of the jaw members.

4. A tool as in claim 1 wherein said actuator means is in the form of a single member.

5. A tool as in claim 1 wherein said actuator means is in the form of first and second substantially parallel actuator members.

6. A tool as in claim 1 wherein the proximal extremity of the push-pull rod is provided with an annular recess, yieldable spring means disposed between the push-pull rod and the elongate tubular member for yieldably urging the push-pull member in a direction proximal of the distal extremity of the elongate tubular member and cooperative means carried by the elongate tubular member and the push-pull rod for limiting proximal movement of the push-pull rod with respect to the elongate tubular member.

7. A clip applier tool for applying a clip inside of a body in a laparoscopic surgical procedure comprising an elongate tubular member having a bore extending therethrough and having proximal and distal extremities, a push-pull rod slidably mounted in said bore and having proximal and distal extremities, actuator means slidably mounted in said bore in said tubular member, means connecting the actuator means to the distal extremity of the push-pull rod, first and second clip applier jaw members having proximal extremities mounted in the bore in said tubular member and having distal extremities adapted for gripping the clip and pivotal means connecting the proximal extremities of the jaw members to said tubular member to permit the distal extremities of the jaw members to move between open and closed positions, each of the jaw members being provided with a slot formed therein which is generally arcuate and curves toward the distal extremity of the respective jaw member and pin means extending through the slots and coupled to the actuator means whereby as the push-pull rod is actuated the jaw members are moved between open and closed positions with respect to each other, the jaw members moving between their open and closed positions at a rate and exerting closure forces on the clip during movement between their open and closed positions whereby the rate of closure decreases and the closure forces increase as the jaw members approach their closed position.

8. A clip applier tool for applying a clip inside of a body in a laparoscopic surgical procedure comprising an elongate tubular member having a bore extending therethrough and having proximal and distal extremities, the elongate tubular member having a diameter not greater than 10 millimeters, a push-pull rod slidably mounted in said bore and having proximal and distal extremities, actuator means slidably mounted in said bore in said tubular member for movement between first and second positions, means connecting the actuator means to the distal extremity of the push-pull rod, first and second clip applier jaw members having proximal extremities mounted in the bore in said tubular member within the actuator means and having distal extremities adapted for gripping clip, pivotal means connecting the proximal extremities of the jaw members, pin and slot means carried b the actuator means and the jaw members for opening and closing the distal extremities of the jaw members upon movement of the actuator means between its first and second positions and the actuator means engaging the jaw members distal of the slots during movement of the jaw members between their first and second positions to form means for inhibiting shifting of the distal extremities of the jaw member during application of the clip.

9. A tool as in claim 8 wherein the actuator means includes first and second actuator members which are generally semi-circular in cross-section.

10. A clip applier tool comprising an elongate tubular member having a bore extending therethrough and having proximal and distal extremities, a push-pull rod slidably mounted in said bore and having proximal and distal extremities, actuator means slidably mounted in said bore in said tubular member for movement between first and second positions, means connecting the actuator means to the distal extremity of the push-pull rod, first and second clip applier jaw members mounted in the bore in said tubular member and having proximal and distal extremities, pivotal means connecting the proximal extremities of the jaw members, pin and slot means carried by the actuator means and the jaw members for opening and closing the distal extremities of the jaw members upon movement of the actuator means between its first and second positions, the push-pull rod being provided with a bore extending therethrough and the actuator means including a bore in communication with the bore in the push-pull rod in communication with the first and second jaw members so that when a saline solution is introduced through the bore of the push-pull rod, the saline solution is introduced to the first and second jaw members to cleanse the same.

11. A clip applier tool comprising an elongate tubular member having a bore extending therethrough and having proximal and distal extremities, a push-pull rod slidably mounted in said bore and having proximal and distal extremities and a bore extending between its proximal and distal extremities, first and second clip applier jaw members mounted in the bore in said tubular member and having proximal and distal extremities, pivotal means connecting the proximal extremities of the jaw members to permit the distal extremities of the jaw members to move between open and closed positions, actuator means coupling the jaw members to the distal extremity of the push-pull rod and means mounted on the proximal extremity of the push-pull rod in communication with the bore of the push-pull rod for introducing a solution through the bore of the push-pull rod.
