Abstract
Abstract @ An instrument (100) for applying clips to a surgical site has an applicator with two jaws (146) which are movable between open and closed positions. A mechanism (132) 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 (148) 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 (248) secured to the mechanism.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
221 words
A surgical instrument (100) for applying clips to a surgical site, comprising applicator means having a pair of cooperating jaws (146) 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 one of the clips 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 presented to said site, said mounting means comprising a handle (102,104), an elongate hollow barrel (142) having a longitudinal axis and being mounted in said handle for turning movement relative thereto about said axis, said barrel having an extension (156) of circular cross section at least in part located within said handle, and control means operative at the option of a user for effecting said angular displacement of said barrel, said control means comprising cooperating motion-transmitting portions (154,152) respectively on said barrel and on a slide member (148) mounted for translatory movement to and fro relative to said handle and lengthwise of said longitudinal axis, said instrument being capable of single hand actuation of said jaws and said angular displacement.
Claim 2
Dependent Claim
221 words
A surgical instrument (100) for applying clips to a surgical site, comprising applicator means having a pair of cooperating jaws (146) 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 one of the clips 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 presented to said site, said mounting means comprising a handle (102,104), an elongate hollow barrel (142) having a longitudinal axis and being mounted in said handle for turning movement relative thereto about said axis, said barrel having an extension (156) of circular cross section at least in part located within said handle, and control means operative at the option of a user for effecting said angular displacement of said barrel, said control means comprising cooperating motion-transmitting portions (154,152) respectively on said barrel and on a slide member (148) mounted for translatory movement to and fro relative to said handle and lengthwise of said longitudinal axis, said instrument being capable of single hand actuation of said jaws and said angular displacement.
Claim 3
Dependent Claim
100 words
A surgical instrument according to claim 1, the elongate hollow barrel at least in part accommodating said supply means, said barrel having a leading end and a trailing end, said trailing end being provided with said 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 the motion-transmitting portion of the slide member being 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.
Claim 4
Dependent Claim
23 words
A surgical instrument according to claim 1 or 2, wherein the slide member is slidable in a slot extending lengthwise of the handle.
Claim 5
Dependent Claim
45 words
A surgical instrument according to claim 3, wherein the handle has a cutout constituting said slot and extending along said axis, the cutout being flanked by respective edge portions and the slide member having lateral marginal portions which rest and slide upon said edge portions.
Claim 6
Dependent Claim
32 words
A surgical instrument according to any preceding claim, wherein a trigger member is connected to the handle for displacement relative thereto and is connected to said supply means to effect operation thereof.
Claim 7
Dependent Claim
27 words
A surgical instrument according to claim 5, wherein the trigger is displaceable relative to the handle about a pivot axis which extends crosswise of said longitudinal axis.
Claim 8
Dependent Claim
23 words
A surgical instrument according to claim 5 or 6, wherein the trigger member has an axis at an obtuse angle to said path.
Claim 9
Dependent Claim
56 words
A surgical instrument according to any preceding claim, wherein said supply means feeds a string of said clips and the instrument includes means associated with said supply means for retracting all except the respective leading clip of said string of clips in a direction -away from said jaws prior to said leading clip being completely cinched.
Claim 10
Dependent Claim
25 words
A surgical instrument according to any preceding claim, wherein at least the jaws of the applicator means are mounted for angular displacement with the barrel.
