Abstract
A surgical stapling instrument for performing a vascular anastomosis procedure comprises an elongated body 10 and a needle 12 having a hook 12b for penetrating and everting the edges 56, 58 of tissue to be joined. The needle 12 is slidable in the body 10 between an extended position as shown and a retracted position wherein the hook is engaged with the end 10a of the body. A stapling mechanism includes a slidable pusher 40 for driving a staple 36 longitudinally of the body 10 against the inside of the hook 12b for deformation of the staple into penetrating engagement with the everted tissue edges 56, 58.
Claims12
A surgical stapling instrument for stapling edges of tissue to be joined, the instrument comprising an elongated body and, carried by the body, a rigid member having a hooked end for penetrating the edges of tissue to be joined and stapling means for applying a staple having opposed legs to the edges held by the hooked end of the rigid member such that each leg penetrates an edge of tissue and substantially simultaneously deforms toward one another against the hooked end to join the edges of tissue.
A method of stapling the edges of tissue to be joined, comprising the steps of:
- a) penetrating the edges of tissue to be joined with a rigid member having a hooked end;
- and
- b) applying a staple having opposed legs to the edges held by the hooked end of the rigid member such that each leg penetrates an edge of tissue and substantially simultaneously deforms toward one another against the hooked end to join the edges of tissue.
A surgical stapling instrument for stapling folds of tissue to be joined, the instrument comprising an elongated body and, carried by the body, a rigid member having a hooked end for penetrating the folds of tissue to be joined and stapling means for applying a staple having opposed lees to the folds by the hooked end of the rigid member such that each leg penetrates a fold of tissue and substantially simultaneously deforms toward one another against the hooked end to join the folds of tissue.
A method of stapling folds of tissue to be joined, comprising the steps of:
- a) penetrating the folds of tissue to be joined with a rigid member having a hooked end;
- and
- b) applying a staple having opposed legs to the folds held by the hooked end of the rigid member such that each leg penetrates a fold of tissue and substantially simultaneously deforms toward one another against the hooked end to join the edges of tissue.
