Endoscopic surgical instrument for tissue coagulation and separation has pivoted jaws with coagulation surfaces and tissue separation surfaces operated via displacement rod and lever mechanism

摘要

The instrument has 2 cooperating jaws pivoted about an axis at the distal shaft end of the instrument in mirror symmetry, each provided with a tissue coagulation device with mirror symmetrical coagulation surfaces and a tissue separation surface, extending in the direction of the pivot axis. The operation of the jaws is controlled by a pair of identical levers, coupled to a displacement rod (6) received within the endoscope shaft.
