Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
227 words
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.
Claim 2
Dependent Claim
227 words
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.
Claim 3
Dependent Claim
39 words
A surgical instrument as defined in claim 1, said handle having a cutout extending along said axis and flanked by respective edge portions, and said slide member having lateral marginal portions which rest and slide upon said edge portions.
Claim 4
Dependent Claim
33 words
A surgical instrument as defined in claim 2, said handle including a trigger member connected to the handle for displacement relative thereto about a pivot axis which extends crosswise of said longitudinal axis.
Claim 5
Dependent Claim
201 words
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 including a handle, an elongated hollow barrel having a longitudinal axis and being mounted in said handle for turning movement relative thereto about said longitudinal axis, said barrel having an extension 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 on said barrel and said handle, respectively, said motion-transmitting portions including a slide member mounted on said handle for translatory movement to and fro along said longitudinal axis.
Claim 6
Dependent Claim
201 words
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 including a handle, an elongated hollow barrel having a longitudinal axis and being mounted in said handle for turning movement relative thereto about said longitudinal axis, said barrel having an extension 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 on said barrel and said handle, respectively, said motion-transmitting portions including a slide member mounted on said handle for translatory movement to and fro along said longitudinal axis.
Claim 7
Dependent Claim
71 words
A surgical instrument as defined in claim 4 wherein said slide member has a projection and the other of said motion-transmitting portions is a groove formed in said extension and extending lengthwise of said longitudinal axis as well as being at least in part convoluted thereabout, said projection being slidably engaged in said groove so that translatory movement of said slide member is converted into said angular displacement of said barrel.
Claim 8
Dependent Claim
28 words
A surgical instrument as defined in claim 5, said handle having a slot extending lengthwise of said longitudinal axis and said slide member being slideable in said slot.
