Surgical instrument
First Claim
1. A surgical instrument for applying clips to a surgical site, comprising applicator means having a pair of cooperating jaws which are movable between an open and a closed position;
- supply means for feeding surgical clips to said jaws in a predetermined path for insertion of a clip therebetween while said jaws are in said open position so as to become cinched when said jaws move to said closed position; and
mounting means mounting at least part of said supply means for angular displacement about said path so as to vary the orientation at which said clip is being presented to said site, said mounting means comprising a handle and an elongated hollow barrel at least in part accommodating said supply means, said barrel having a longitudinal axis and being mounted in said handle for turning movement relative thereto about said axis, said barrel having a leading end and a trailing end, said trailing end being provided with an extension of circular cross section, said mounting means further including a groove formed in said extension and extending lengthwise and also circumferentially of said axis, and an operating member slidable in said handle lengthwise of said axis and including a connecting portion riding in said groove so that translatory sliding of said slide member lengthwise of said axis is converted into turning movement of said barrel about said axis.

Abstract
An instrument for applying clips to a surgical site has an applicator with two jaws which are movable between open and closed positions. A mechanism is provided for feeding the respectively leading clip of a string of such clips between the jaws, whereupon the jaws are closed and the leading clip is cinched as it is being applied to the surgical site. To vary the presentation of the clip, i.e., its orientation relative to the surgical site, the mechanism is mounted so that it can turn about a longitudinal axis of the instrument. In one embodiment, a slide button is provided which can be slid forward and backward with one finger of a user, such translatory movement of the button being converted into a turning movement of the mechanism and consequently also of the clip which is being held between the anvils preparatory to its application to the surgical site. In another embodiment, turning movement is effected by rotating a knob secured to the mechanism.
