Abstract
Abstract A ligature and/or suture system for endoscopic surgery, comprising, in combination: a tie for ligature or for suture, slidably mounted in the longitudinal channel of a separate tubular endpiece; and a rigid support including a handle secured to an elongate rod which is provided at its proximal end remote from the handle with a reception cradle suitable for removably receiving the tubular endpiece, and with a through lateral window whereby said cradle opens out to the outside of the support to enable the tie to pass therethrough such that traction exerted on the distal end of the tie relative to the support serves to tighten the ligature or the suture.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
113 words
A ligature and/or suture system for endoscopic surgery, comprising, in combination: a length of suture having proximal and distal ends slidably mounted in the longitudinal channel of a separate tubular endpiece; and a rigid support including a handle secured to an elongate rod which is provided at its distal end remote from the handle with a reception cradle suitable for removably receiving the tubular endpiece, and with a through lateral window, whereby said cradle is placed on the outer surface of said support to enable the suture to pass therethrough and said support configured such that traction exerted on the proximal end of the suture by said support serves to tighten the suture.
Claim 2
Dependent Claim
113 words
A ligature and/or suture system for endoscopic surgery, comprising, in combination: a length of suture having proximal and distal ends slidably mounted in the longitudinal channel of a separate tubular endpiece; and a rigid support including a handle secured to an elongate rod which is provided at its distal end remote from the handle with a reception cradle suitable for removably receiving the tubular endpiece, and with a through lateral window, whereby said cradle is placed on the outer surface of said support to enable the suture to pass therethrough and said support configured such that traction exerted on the proximal end of the suture by said support serves to tighten the suture.
Claim 3
Dependent Claim
32 words
A system according to claim 1 further including a cursor secured to said suture proximal end, wherein the handle of the support is provided with a slideway suitable for receiving said cursor.
Claim 4
Dependent Claim
19 words
A system according to claim 2, wherein the cursor is permanently secured to the proximal end of the tie.
Claim 5
Dependent Claim
30 words
A system according to claim 2, wherein the cursor is permanently mounted on the handle, which cursor is adapted to receive the distal end of the tie in removable manner.
Claim 6
Dependent Claim
20 words
A system according to claim 4, wherein the cursor contains a clip structure engageable with the slideway of said handle.
Claim 7
Dependent Claim
25 words
A system according to claim 2, wherein the slideway includes a groove having converging edges and the cursor has a tenon having complementary right cross-sections.
Claim 8
Dependent Claim
15 words
A system according to claim 1, wherein the tubular endpiece is made of plastics material.
Claim 9
Dependent Claim
20 words
A system according to claim 1, further comprising retaining means contained on the tubular endpiece for receiving said cradle thereon.
Claim 10
Dependent Claim
21 words
A system according to claim 8, wherein the retaining means comprise at least one annular groove formed on the tubular endpiece.
Claim 11
Dependent Claim
22 words
A system according to claim 8 wherein the retaining means comprise a rib formed on the inside surface of the reception cradle.
Claim 12
Dependent Claim
44 words
A system according to claim 8 further comprising distal and proximal ends on the tubular end piece wherein the retaining end means comprises two annular grooves formed on the tubular endpiece respectively in the vicinity of its proximal end and of its distal end.
Claim 13
Dependent Claim
16 words
A system according to claim 1, wherein the proximal end of the tubular endpiece is tapered.
Claim 14
Dependent Claim
44 words
A system according to claim 1, wherein the inside diameter of the longitudinal channel through the tubular endpiece is greater than the diameter of the filament constituting the suture while being less than the transverse size of a slip knot formed on said suture.
Claim 15
Dependent Claim
28 words
A system according to claim 1, wherein the reception cradle is formed by a longitudinal channel that opens out to the proximal axial end of the support rod.
Claim 16
Dependent Claim
19 words
A system according to claim 1, wherein the lateral window extends over the entire length of the reception cradle.
Claim 17
Dependent Claim
47 words
A system according to claim 1, wherein the suture is selected from the group comprising: a ligature filament provided at its proximal end with a preestablished loop having a slip knot; a simple ligature filament; and a suture filament provided with a needle at its proximal end.
Claim 18
Dependent Claim
22 words
A system according to claim 16, wherein the filament of the suture is provided with an auxiliary endpiece at its proximal end.
Claim 19
Dependent Claim
27 words
A system according to claim 17, wherein the auxiliary endpiece has a right cross-section that is greater than that of the channel passing through the tubular endpiece.
Claim 20
Dependent Claim
25 words
A system according to claim 17, wherein the auxiliary endpiece is adapted to be fixed on a cursor that is slidably mounted on the handle.
Claim 21
Dependent Claim
26 words
A system according to claim 1, wherein the suture comprises a preformed loop formed on the length thereof between its distal end and the tubular endpiece.
Claim 22
Dependent Claim
25 words
A system according to claim 1, wherein the proximal end of the tubular endpiece has a surface in the form of half of a torus.
