Embodiment Construction

[0030] refer to Figure 1-Figure 2A , stapler 11 has a handle 12 with a trigger 13 pivotably mounted to the handle at 14. A tube 16 is secured to the handle and has a stapler head 17 at its distal end. The head is bent downwards at an angle of about forty degrees from axis 18 ( figure 1 In A) and has a staple ejection port 19 through which staples are ejected, one staple is ejected each time the trigger is pulled. The trigger coupled to the staple launcher is a two-stage system whereby staples 21 can be advanced from the head to figure 1 and Figure 1A location shown. Then, when the trigger is pulled further, the staples can be fired through the patch and into the tissue.

[0031] One innovative feature is the provision of a mesh manipulator near the exit port of the stapler. As used herein, a "mesh manipulator" does not include the staple itself, but rather a structure other than a staple that is operable to manipulate a surgical mesh. exist figure 1 and Figure 1...

Abstract

A surgical stapler for use during an open hernia repair comprises an elongated shaft having a handle 120 at its proximal end and a downwardly disposed staple discharge head 130 at its distal end. A squeeze trigger 122 on the handle 120 is operable to cause a supply of staples 160 to be selectively discharged from the port. One or more mesh manipulators 150 are provided on the head 130 and serve to assist in positioning or otherwise manipulating surgical mesh prior to fixation with the staples.

More particularly, but not exclusively, the present application relates to a surgical stapler having a distal effector for positioning a surgical patch prior to application of the staples. Background technique [0004] Edited by Robert J. Fitzgibbons and A. Gerson Greenburg, Lippincoot Williams & Wilkins, Philadelphia, 2002 Nyhus and Condon's Hernia Chapter 14, "The Transabdominal Preperitoneal Laparoscopic Herniorrhaphy", pp. 149-268, fifth edition, describes some of the steps used to repair an inguinal hernia. A patch of monofilament polypropylene is mentioned as a suitable material for use in such procedures. After the patch is shaped and pos...
