Abstract: A hemostatic clip for surgical use is disclosed having grooves on the inner surfaces of the legs which form an asterisk type pattern upon closure, knee bends in each leg which are opposed by notches or grooves that enhance the ability of the legs to fully straighten upon closure, and distal flat surfaces on the ends of the clip legs to prevent scissoring and ensure hemostasis when the clip is closed.

Abstract: A surgical instrument useful for forming a buttonhole through the stomach walls in gastroplastic surgery has a forceps handle, a hinge, and two jaws. The jaws form an aperture proximal the hinge which grasps the tubular pouch formed along the stomach wall. At the distal end of the jaws are a pair of rings which compress and define the location of a stapled buttonhole in the stomach walls. A cup is attached to one ring which is adapted to hold the nut and anvil of a stapling device which is used to cut the buttonhole in the center of the compressed rings and to affix a ring of staples about the periphery of the buttonhole.
