Laparoscopic forceps assembly

A laparoscopic forceps comprising:

• a handpiece including a distal end portion;
• a tubular member protruding from the distal end portion of the handpiece, the tubular member having a distal end,
• a pair of jaws having legs that are disposed within the tubular member and partially protruding from the distal end of the tubular member, the pair of jaws and the tubular member being movable relative to each other in a direction parallel to a longitudinal axis of the tubular member;
• wherein each of the pair of jaws has an arcuate section, and the pair of jaws are closable by advancing the tubular member over the arcuate section of the jaws;
• and
• an operable mechanism for creating relative motion between the pair of jaws and the tubular member along a direction parallel to the axis of the tubular member,
• wherein at the distal end portion of the tubular member there is a profile shape that is non-circular;
• wherein substantially all of the tubular member has a generally circular cross-section and the distal end of the tubular member includes a camming shaft that creates the non-circular profile shape;
• and
• wherein the camming shaft is connected to an internal wall of the tubular member at the distal end of the tubular member.

A laparoscopic forceps comprising:

• a. a handpiece;
• b. a jaw bias mechanism;
• c. a tubular member including:
• i. an outer tube, and
• ii. an inner tube, wherein the outer tube and inner tube are movable relative to each other when acted upon by the jaw bias mechanism;
• d. jaws extending from the tubular member and at least partially through the tubular member;
• and
• e. a biasing element that biases the inner tube and outer tube relative to each other so that the biasing element biases the jaws open;
• wherein the jaws pivot on one or more axes that are anchored to the inner tube;
• and
• wherein the outer tube overruns the jaws so that the jaws are moved towards each other;
• and
• wherein a pin is connected to the outer tube that extends between the jaws so that upon movement of the outer tube axially towards a proximal end of the laparoscopic forceps, the pin moves the jaws apart.
