Abstract
Abstract A surgical clip has a pair of arms (10, 11) which may be crimped together by applying a tensile force to a tang (19) with a jaw (50) of an applicator tool. This tool has a body (56) which abuts against both ends of a bridge portion (12) of the clip so that the tensile force may bend the plastically deformable bridge portion (12) to crimp the arms (10, 11) together. As the bridge portion (12) bends, the points of contact between the bridge portion (12) and the body (56) of the applicator tool move closer together, thereby increasing the tensile force needed to bend further the bridge portion to above the value at which a neck (21) connecting the bridge portion (12) and tang (19) fractures. <IMAGE>

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
59 words
CLAIMS 1.A.surgical clip comprising a plastically deformable body, a tang for deforming the body and a neck connecting the tang to the body, the neck being designed to break upon application of a predetermined tensile force to the tang and the body being deformable by application to the tang of a tensile force less than the predetermined tensile force.
Claim 2
Dependent Claim
67 words
A surgical clip according to Claim 1, wherein the body comprises a plastically deformable bridge portion and a pair of spaced arms extending side by side in one direction from opposite ends of the bridge portion, the tang extending from the bridge portion in a direction opposite to that of the arms, for deforming the bridge portion so as to bring the arms together around apposed tissues.
Claim 3
Dependent Claim
23 words
A surgical clip according to Claim 2, further comprising an enlarged head on the tang to facilitate gripping thereof by an applicator tool.
Claim 4
Dependent Claim
39 words
A surgical clip according to Claim 2 or Claim 3, wherein each of the arms is arcuate with the concave surface facing the other arm whereby tissue may be retained between the arms when the bridge portion is deformed.
Claim 5
Dependent Claim
36 words
A surgical clip according to any of Claims 2 to 4, wherein the arms terminate at distal tips which are sufficiently rounded to avoid puncturing tissue captured between the arms when the bridge portion is deformed.
Claim 6
Dependent Claim
52 words
A surgical clip according to any of Claims 2 to 5, further comprising a pair of spaced shoulders on the bridge portion on respective sides of the neck for supporting the clip as tension is applied to the tang, to create a bending moment in the bridge portion to produce deformation thereof.
Claim 7
Dependent Claim
12 words
A surgical clip according to Claim 6, wherein the shoulders are flat.
Claim 8
Dependent Claim
39 words
A surgical clip according to Claim 7, wherein the shoulders face away from or in the same direction as one another and lie at an obtuse angle in the range from 1200 to 180 with respect to one another.
Claim 9
Dependent Claim
23 words
A surgical clip according to Claim 8, wherein the shoulders lie at an obtuse angle of about 120 with respect to one another.
Claim 10
Dependent Claim
17 words
A surgical clip substantially as described with reference to Figures 2 to 7 of the accompanying drawings.
Claim 11
Dependent Claim
55 words
An applicator tool for deforming a surgical clip of the type having a deformable body with a tang extending therefrom and spaced shoulders on the body on respective sides of the tang, the tool comprising means for gripping and applying tension to the tang of the clip and means for simultaneously engaging the clip shoulders.
Claim 12
Dependent Claim
27 words
A tool according to Claim 11, wherein the engaging means comprises a pair of spaced stationary jaw faces adapted to engage respective ones of the clip shoulders.
Claim 13
Dependent Claim
40 words
A tool according to Claim 12, wherein the jaw faces are flat, face towards or in the same direction as one another and lie at an obtuse angle in the range from 120" to 180' with respect to one another.
Claim 14
Dependent Claim
18 words
A tool according to Claim 13, wherein the jaw faces lie at an angle of about 150 .
Claim 15
Dependent Claim
35 words
A tool according to any one of Claims 12 to 14, wherein the gripping and tensioning means comprises a jaw movable with respect to the stationary jaw faces and means for retracting the movable jaw.
Claim 16
Dependent Claim
39 words
A tool according to Claim 15, wherein the retracting means comprises a cam and a cam follower, the cam being connected to manipulating means forming part of the tool, and the cam follower being connected to the movable jaw.
Claim 17
Dependent Claim
33 words
A tool according to Claim 16, wherein the cam includes an actuating surface lying obliquely to the axis of the movement of the jaw, and the cam follower abuts against the actuating surface.
Claim 18
Dependent Claim
12 words
A tool according to Claim 17, wherein the actuating surface is arcuate.
Claim 19
Dependent Claim
15 words
Atool according to Claim 17 or Claim 18, wherein the cam follower is a roller.
Claim 20
Dependent Claim
42 words
A tool according to any of Claims 16 to 19, wherein the manipulating means comprises at least one flexible leaf, a portion of which is deflectable with respect to the rest of the tool, the cam being mounted on the deflectable portion.
Claim 21
Dependent Claim
45 words
A tool according to Claim 20, wherein the manipulating means comprises two flexible leaves, each leaf being connected at its ends to the rest of the tool, whereby the deflectable portions of the leaves can be moved towards one another by there being squeezed together.
