Surgical tissue or vessel suturing instrument - has suturing head with two identical jaw components orthogonal to instrument axis

摘要

The surgical suturing instrument comprises needle and thread arranged so that the needle runs parallel to the instrument axis of insertion. The instrument (1) needle head consists of two jaws (2, 3) at right angles to the axis (4) of the instrument, one jaw (2) moving axially to and from the second jaw (3) and fitted at the tip with an arrowhead-recessed clamp (5, 7, 8) to position the pointed needle (10) as required. The axially fixed second jaw also has an arrowhead-recessed clamp (12, 17, 18) at one end, which opposes the first clamp and positions the needle toward the first clamp for fixing. A swivel lever (14) at one end of the second jaw is remotely operated along the instrument axis to clamp the needle in the second jaw clamp or release it. ADVANTAGE - Facility for endoscopic operation without need for additional implements.
