Surgical clamp possessing a combined parallel and scissor style clamp head
First Claim
1. A surgical clamp, comprising:
- a clamp head;
a first jaw and a second jaw, each mounted to the clamp head for movement toward and away from each other;
an operative mechanism coupled to the proximal end of at least one of the first jaw and the second jaw; and
an actuating structure connected to the operative mechanism for imparting a parallel opening movement to at least one of the first jaw and the second jaw from a first position to a second position where the first jaw and the second jaw are spaced apart and parallel to one another, the actuating structure selectively imparting further scissors-like opening movement to at least one of the first jaw and the second jaw from the second position to a third position where the first jaw and the second jaw are spaced apart a distance greater than that of the second position.

Abstract
A surgical clamp includes a clamp head, and a first jaw and a second jaw, each mounted to the clamp head for movement toward and away from each other. The clamp also includes an operative mechanism coupled to the proximal end of at least one of the first jaw and the second jaw, and an actuating structure connected to the operative mechanism for imparting a parallel opening movement to at least one of the first jaw and the second jaw from a first position to a second position where the first jaw and the second jaw are spaced apart and parallel to one another, the actuating structure selectively imparting further scissors-like opening movement to at least one of the first jaw and the second jaw from the second position to a third position where the first jaw and the second jaw are spaced apart a distance greater than that of the second position.

14. A clamp, comprising:
-
a first jaw including a first slot extending along a first plane;
a second jaw including a second slot extending along a second plane, the first and second jaws each being arranged such that the first and second planes are substantially parallel to each other, one of the first and second slots having an angled slot portion extending along a third plane at an angle to the first and second planes;
a linkage mechanism having at least a first pin for engagement in the first slot and at least a second pin for engagement in the second slot; and
an actuator for displacing the linkage mechanism from a first position, wherein the first pin and the second pin are positioned in the first and second slots in a substantially parallel configuration, to a second position, wherein one of the first pin and the second pin is positioned within the angled slot portion. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A method of occluding a body vessel with a surgical clamp including a clamp head mounting a pair of elongate jaws for movement toward and away from each other, the method comprising:
-
coupling an operative mechanism to proximal ends of each the jaws; and
connecting an actuating structure to the operative mechanism for imparting parallel opening movement to at least a first one of the pair of jaws from a closed position into a parallel spaced position with a second the jaw, and causing the actuating structure to selectively impart further scissors-like opening movement to the at least first one of the pair of jaws into a wider open position between the jaws. - View Dependent Claims (22, 23)

24. A method of occluding a blood vessel with a clamp, comprising the steps of:
-
providing a clamp head, comprising;
a first jaw and a second jaw, each mounted to the clamp head for movement toward and away from each other;
an operative mechanism coupled to the proximal end of at least one the first jaw and the second jaw; and
an actuating structure connected to the operative mechanism for imparting parallel opening movement to at least one of the first jaw and the second jaw from a first position to a second position where the first jaw and the second jaw are spaced apart and parallel to one another, the actuating structure selectively imparting further scissors-like opening movement to at least one of the first jaw and the second jaw from the second position to a third position where the first jaw and the second jaw are spaced apart a distance greater than that of the second position;
creating an opening in a patient'"'"'s body;
positioning the first jaw and the second jaw in the first position;
passing the clamp head through the opening;
actuating the actuating structure to cause one of the first jaw and the second jaw to move to the third position;
positioning the first jaw and the second jaw such that the blood vessel is disposed between first jaw and the second jaw; and
actuating the actuating structure to cause one of the first jaw and the second jaw to move to the first position to clamp the blood vessel. - View Dependent Claims (25, 26, 27, 28)
