Abstract

Abstract Apparatus for ligating blood vessels, nerves or other anatomical structures, such as Fallopian tubes, utilizing a modified form of a standard hemostat, including a removable pair of hemostat jaw inserts of non-toxic, substantially rigid material, each releasably secured to a jaw of the hemostat, each insert having removably formed therein at least one clip member, locking structure contained by at least one of the clip members adapted lockingly to engage the other of the clip members, whereby the jaws of the hemostat can be opened to any desired width and then closed, locking the clip members to form a ligating clip over or in a blood vessel or other anatomical structure and opening the jaws causes the joined clip members to break away from the inserts. A method of using said apparatus and process comprising the steps of removably locking the inserts on the jaws of a hemostat, opening the jaws to any desired width and placing the jaws on opposed sides of a blood vessel, nerve or other anatomical structure to be closed, closing the jaws, engaging the locking structure of the clip members on either side of the anatomical structure, opening the jaws to break away the clip members from said inserts and leaving the clip members in locking engagement on or in the blood vessel or other anatomical structure.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 165 words
An article adapted to be attached removably and lockingly to a pair of opposed jaws of an applicator, comprising: (a) A pair of opposed, elongated plastic clip assembly members, each defining an elongated aperture; (b) Each clip assembly member having integral means lockingly to interconnect that clip assembly member to a jaw of an applicator; (c) Each clip assembly member having an inner surface, said inner surfaces being adapted to oppose each other; (d) At least two plastic clip members, one seated in the elongated aperture of one clip assembly member and the other seated in the elongated aperture of the other clip assembly member; (e) Shearable plastic web means releasably securing each clip member to its corresponding clip assembly member; (f) Each clip member, web means and clip assembly member comprising a unitary structure of one material; and (g) Each clip member having integral locking means whereby two opposing clip members lockingly interengage about an anatomical structure when said clip members are pressed together.
Claim 2
Dependent Claim 165 words
An article adapted to be attached removably and lockingly to a pair of opposed jaws of an applicator, comprising: (a) A pair of opposed, elongated plastic clip assembly members, each defining an elongated aperture; (b) Each clip assembly member having integral means lockingly to interconnect that clip assembly member to a jaw of an applicator; (c) Each clip assembly member having an inner surface, said inner surfaces being adapted to oppose each other; (d) At least two plastic clip members, one seated in the elongated aperture of one clip assembly member and the other seated in the elongated aperture of the other clip assembly member; (e) Shearable plastic web means releasably securing each clip member to its corresponding clip assembly member; (f) Each clip member, web means and clip assembly member comprising a unitary structure of one material; and (g) Each clip member having integral locking means whereby two opposing clip members lockingly interengage about an anatomical structure when said clip members are pressed together.
Claim 3
Dependent Claim 42 words
An article as set forth in claim 1, wherein said first named means comprises at least one locking means proximate to one end of each of said clip assembly members wherein it lockingly engages and forms an extension of said hemostat jaws.
Claim 4
Dependent Claim 26 words
An article as set forth in claim 1, wherein said first-named means comprises at least one locking means proximate each end of said clip assembly member.
Claim 5
Dependent Claim 47 words
An article as set forth in claim 1, wherein the inner surface of each clip member and the inner suface of its corresponding clip assembly member are substantially coplanar and each of said surfaces have a non-planar face formed therein to facilitate grasping of an anatomical structure.
Claim 6
Dependent Claim 89 words
An article as set forth in claim 1, wherein each said clip assembly member has a sleeve at one end adapted to engage the distal end of a hemostat jaw and a male member proximate its other end adapted lockingly to engage in an aperture in a hemostat jaw and wherein each said clip member is fastened to its clip assembly member by a plurality of thin webs of material, each of said clip members having a locking member proximate each end to lockingly engage the other clip member.
