Three jaw clamp apparatus and system for occlusion and eversion of blood vessel and method thereof

A three jaw clamp apparatus for occluding a blood vessel and opening lumen of the blood vessel, the three jaw clamp apparatus comprising:

• a first member, a second member, and a third member;
• wherein each the member comprises a handle and a jaw;
• and
• wherein the first member and the second member being laterally moveable toward and away from one another;
• wherein the third member being laterally moveable toward and away from the first member;
• wherein the first member and the second member occlude the blood vessel in between corresponding jaws when a pinch force is applied on the handle of the first member and the handle of the second member comprising:
• applying the pinch force, on the handle of the first member and the handle of the second member, causing corresponding jaws to open;
• positioning the open jaws about the blood vessel;
• and releasing the pinch force, on the handle of the first member and the handle of the second member, causing the open jaws to close on the blood vessel;
• wherein the third member and the first member occlude an adventitia of the blood vessel in between corresponding jaws when a pinch force is applied on the handle of the third member and the handle of the first member comprising:
• applying the pinch force, on the handle of the third member and the handle of the first member, causing corresponding jaws to open;
• positioning the adventitia between the open jaws;
• and
• releasing the pinch force, on the handle of the third member and the handle of the first member, causing the open jaws to close on the adventitia;
• and
• wherein the third member and the first member maintain a tension in the adventitia by creating a holding tension on the adventitia to open the blood vessel, wherein the jaw of the third member having width less than 60% of that of the jaw of the first member, and wherein the distance between tip of the jaw of the third member and a root of the adventitia is less than quarter of the perimeter of maximum size blood vessel to be occluded by the three jaw clamp apparatus.
