the driver and cutter 80 is caused by the gliding coaction of angled projection 78 as it rides along sloping ramp 84 let us now turn to fig1 through 17 where there are shown a series of schematic views depicting the operation of the surgical instrument fig1 shows instrument 10 and coupling members 42 44 46 located in colon 30 while herein illustrated and described is the use of the instrument and coupling members in conjunction with colon repair it should be understood that use thereof is equally applicable for the repair of other tubular organs such as the large and small bowel and the esophagus to name but a few here colon 30 having wall portions 32 34 and free ends 36 38 is shown with the free ends being gathered against core 28 coupling member 42 supported by core 28 and end knob 48 is located in one end of colon 30 while head portion 16 is located in the other end of the colon coupling member 42 is ready to be moved into approximation with member 44 fig1 shows the coupling members approximated core 28 having been moved to the left to bring ends 36 38 into contact but before locking of the members and before tissue and coupling member cutting compression of tissue between members 42 44 is achieved by the movement of knob 18 and pin 54 through curved portion 56 at the handle end of the instrument and member 42.
