1. A clamping apparatus for applying surgical clamps, comprising:

  • a pistol grip actuator having an operating grip movable from an intermediate position in a first direction for setting one of said surgical clamps and in a second direction for disassembly of said clamping apparatus;

    a hollow shaft having a first end removably connected to said pistol grip actuator;

    a removable magazine for holding said surgical clamps;

    slide means for slidably receiving said removable magazine in said hollow shaft through an open second end of said hollow shaft;

    said removable magazine having a channel containing said surgical clamps;

    a forceps closing member slidably disposed in said hollow shaft beneath said removable magazine and responsive to movement of said operating grip;

    said removable magazine having an elastic catch biased downward for engaging a catch member of said hollow shaft extending through said forceps closing member;

    forceps means, slidably disposed in said forceps closing member, for receiving and compressing one of said surgical clamps by a cam action movement of said forceps closing member in response to actuation of said operating grip in said first direction;

    said forceps means having a catch hook engageable with a stop member extending from said hollow shaft and through said forceps closing means to maintain said forceps means fixed relative to said hollow shaft permitting said cam action movement of said forceps closing means to compress said one of said surgical clamps;

    said forceps closing means having a filler member disposed to maintain engagement of said catch hook with said stop member during said cam action movement of said forceps closing means;

    said magazine having a feeding slide for advancing said surgical clamps toward said second end of said hollow shaft;

    a push rod means extending from said pistol grip actuator into said hollow shaft responsive to movement of said operating grip in said first direction;

    means for disengagably connecting said feeding slide with said push rod means to permit advancement of said surgical clamps in response to movement of said operating grip; and

    said forceps closing means being responsive to movement of said operating grip in said second direction to effect displacement of said filler member from said catch hook to permit removal of said forceps means and displacement of said elastic latch from said catch member to allow removal of said magazine.
