Abstract

A surgical apparatus for use in laparoscopic surgery being adaptable to provide for clipping, cutting or clamping. The device has a probe having an instrument attached to one end to be inserted in a patient. Slidably disposed over the probe is a sliding sleeve which applies force to the instrument end of the probe to effect the desired action. In one embodiment the probe may be rotatable, while in another embodiment the instrument ends are interchangeable.

Claims

1. A surgical instrument for use in applying clips to tissue, the instrument adapted for passage through a surgical sleeve or cannula and into a bodily cavity, the instrument comprising:

a handle for gripping by a user'"'"'s hand;

an elongate probe extending from the handle and adapted for passage through the surgical sleeve, the probe including;

a generally tubular probe sleeve extending from the handle; and

a probe member extending from the handle, generally concentrically through the probe sleeve, and terminating in an end;

a pair of jaws rotatably coupled to the end of the probe member, the jaws for selectively compressing the surgical clip about a portion of tissue in the bodily cavity, the jaws including a pair of camming surfaces and extending a fixed axial distance from the handle, at least the jaws being freely rotatable relative to the handle to permit the handle to be rotated with the jaws in a selected position in the bodily cavity;

seal means disposed in the probe to prevent escape of fluid from the bodily cavity through the surgical instrument; and

actuator means coupled to the probe to selectively actuate the jaws by longitudinal movement of the probe sleeve over the camming surfaces of the jaws, wherein the jaws remain at the fixed longitudinal distance from the handle.

2. The surgical instrument according to claim 1 wherein the seal means comprises a resilient seal ring disposed in the probe sleeve and sealingly engaging the probe member.

3. A surgical instrument for use dissecting tissue, the instrument adapted for passage through a surgical sleeve or cannula and into a bodily cavity, the instrument comprising:

a handle for gripping by a user'"'"'s hand;

an elongate probe extending from the handle and adapted for passage through the surgical sleeve, the probe including;

a generally tubular probe sleeve extending from the handle; and

a probe member extending from the handle, generally concentrically through the probe sleeve, and terminating in an end;

a pair of scissor jaws rotatably coupled to the probe member, the scissor jaws for selectively dissecting tissue in the bodily cavity, the jaws including a pair of camming surfaces and extending a fixed axial distance from the handle, at least the scissor jaws being freely rotatable relative to the handle to permit the handle to be rotated with the scissor jaws in a selected position in the bodily cavity;

seal means disposed in the probe to prevent escape of fluid from the bodily cavity through the surgical instrument; and

actuator means coupled to the probe to selectively actuate the scissor jaws by longitudinal movement of the probe sleeve over the camming surfaces of the jaws, wherein the jaws remain at the fixed longitudinal distance from the handle.

4. The surgical instrument according to claim 3 wherein the seal means comprises a resilient seal ring disposed in the probe sleeve and sealingly engaging the probe member.

5. A surgical instrument for use in manipulating tissue, the instrument adapted for passage through a surgical sleeve or cannula and into a bodily cavity, the instrument comprising:

a handle for gripping by a user'"'"'s hand;

an elongate probe extending from the handle and adapted for passage through the surgical sleeve, the probe including;

a generally tubular probe sleeve extending from the handle and

a probe member coupled to the actuator means and extending from the handle, generally concentrically through the probe sleeve, and terminating in an end;

a pair of jaws rotatably coupled to the probe member, the jaws including a pair of camming surfaces and extending a fixed axial distance from the handle, at least the jaws being freely rotatable relative to the handle to permit the handle to be rotated relative to the jaws with the jaws in a selected position in the bodily cavity;

seal means disposed in the probe to prevent escape of fluid from the bodily cavity through the surgical instrument; and

actuator means coupled to the probe to selectively actuate the jaws by longitudinal movement of the probe sleeve over the camming surfaces of the jaws, wherein the jaws remain at the fixed longitudinal distance from the handle.

6. The surgical instrument according to claim 5 wherein the jaws are adapted to compress a surgical clip about a portion of tissue in the bodily cavity.

7. The surgical instrument according to claim 5 wherein the jaws are sharpened scissor jaws adapted to dissect tissue in the bodily cavity.

8. The surgical instrument according to claim 5 wherein the seal means comprises a seal ring disposed in the probe sleeve and sealingly engaging the probe member.
