Abstract
An apparatus for surgically manipulating tissue without causing irreparable damage to the tissue during retention and manipulation is disclosed. The tissue manipulator apparatus includes a shaft having proximal and distal ends, a rod member with proximal and distal ends circumferentially contained within the shaft, a contact member having at least one tissue contact surface area comprising a plurality of projections connected to the distal end of the rod member, and a handle member attached near the proximal end of the shaft. The plurality of projections preferably point in the direction of retraction of the targeted tissue. The apparatus is designed to distribute the interdentating contact over the tissue micro surface area in an effort to reduce reliance on pressure induced friction alone.
Claims16
A micro traumatic tissue manipulator apparatus comprising:
- an elongated shaft having proximal and distal ends;
- a contact member comprising a set of co-acting jaw members wherein each jaw member includes an inner tissue contact surface wherein said contact member is attached near the distal end of said shaft and said tissue contact surface comprises a plurality of at least one of peaked projections and pointed projections with said projections protruding in at least one direction of traction, and wherein each of said co-acting jaw members further comprises a first distal end and a second proximal end, said second proximal ends of said jaw members being connected to one another and said first distal ends maintaining a spaced apart distance from one another in a fully closed position of the co-acting jaw members;
- and
- a handle member attached near said proximal end of the shaft.
A micro traumatic tissue manipulator apparatus comprising:
- an elongated shaft having proximal and distal ends;
- a contact member comprising a set of co-acting jaw members wherein each jaw member includes at least one tissue contact surface having at least one of a continuous semi-circular shape and a continuous semi-elliptical shape, wherein said contact member is attached near said distal end of the shaft and said tissue contact surface comprises a plurality of sharp projections, and wherein each of said co-acting jaw members further comprises a first distal end and a second proximal end, said second proximal ends of said jaw members being connected to one another and said first distal ends maintaining a spaced apart distance from one another in a fully closed position of the co-acting jaw members;
- and
- a handle member attached near said proximal end of the shaft.
A method of tissue prehension comprising the steps of:
- a) contacting the tissue surface with a contact member comprising a set of co-acting jaw members wherein each jaw member includes an inner tissue contact surface having a plurality of sharp projection tips;
- b) puncturing the tissue surface with said plurality of sharp projections tips;
- c) maintaining a minimal amount of pressure against the projections to maintain contact between the tissue and the projections, while maintaining a spaced-apart distance between the co-acting jaw members at a fully closed position;
- and
- d) imparting a torque to the tissue to effect hooking of the tissue on the projections' non cutting base.
