Instrument for laparoscopic tubal cauterization

Instrument for laparoscopic tubal cauterization by intra-abdominal cavity penetration comprising:

• a grip member;
• an elongated narrow probe element having one end removably attached to said grip member whereby said probe element may be disposed of after use;
• said probe element including a sleeve member;
• said sleeve member being shaped to be easily insertable through a small cut in the abdominal wall of said cavity and to reach a fallopian tube therein;
• a pair of electrically conductive bi-polar elements carried by said probe element within said sleeve member in such spaced relationship to one another as to avoid electrical short therebetween and longitudinally displaceable within said sleeve member;
• said elements having cooperating extremities defining tube-grasping portions;
• said extremities cooperating with the open end of said sleeve member for causing a strong squeezing action by said extremities externally on said tube being grasped;
• means on said grip member connecting each said member connecting each said bi-polar elements to an external power source and allowing a current discharge between the tube-grasping portions externally on the squeezed tube for complete coagulation of said tube.
