Abstract
A two-part modular tool and method for use thereof in conjunction with laparoscopic techniques enhances such techniques by enabling tools to be manipulated within a body cavity through small needle holes. The tool has an instrument head initially inserted through a laparoscopic port and an acuminate shaft which intracorporeally attaches to the instrument head. The instrument head is then manipulable through the needle hole at the site of desired use. The instrument head may be any tool configuration useful in surgical procedures which can be miniaturized to pass through a laparoscopic port.
Claims23
A two-art modular laparoscopic tool for use with laparoscopic surgical procedures in a body cavity, comprising:
- an instrument head comprising:
- an instrument passable through a laparoscopic port;
- and
- an elongate shank attached to said instrument;
- and
- an elongate shaft having a tapered end portion with first detachable attachment means for detachable attachment to said shank and an opposite handle portion, said tapered end portion insertable through a needle hole into said body cavity for intracorporeal detachable attachment to a second detachable attachment means in said shank for detachable attachment to said shaft;
- wherein said tapered end portion comprises a sharp cutting point for puncture and passage through a body wall.
A multi-purpose instrument useful in laparoscopic surgery, comprising:
- an elongate narrow shaft having a first tapered end culminating in a sharp point for surgically puncturing a body wall for forming needle hole, a second enlarged end comprising a handle for manipulation of said multi-purpose instrument through said needle hole, and first locking means on said first tapered end;
- and
- a laparoscopic surgical instrument head having a shank with a hollow interior with a second locking means therein,;
- wherein said first locking means is detachably attachable to said second locking means.
A laparoscopic method for performing surgical procedures in a body cavity, comprising:
- establishing a laparoscopic trocar port across a body wall into a body cavity;
- introducing a miniature instrument having a shank joined thereto thrown said port into said body cavity with a laparoscopic insertion tool;
- puncturing said body wall with a needle to form a needle hole and inserting therethrough a thin acuminate shaft having one end configured to attach to said shank;
- intracorporeally joining said shaft to said shank while manipulating said instrument through said port;
- and
- detaching said insertion tool from said instrument for manipulation by said shaft passing through said needle hole.
