Abstract
Abstract An endoscopic loop including an applying instrument comprises a pre-knotted loop of surgical suture material and a hollow shaft in the interior space of which the free thread portion runs. The free thread portion extends at least up to the proximal end of the shaft. In the interior space an actuating mechanism is mounted, the proximal end of which essentially extends up to the proximal end of the shaft. At the distal end of the actuating means a knife is attached which cuts the free thread portion upon actuation of the device.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
133 words
Endoscopic loop and applying instrument, comprising: a pre-knotted loop of surgical suture material having a free suture thread portion; and an instrument having a hollow shaft with proximal and distal ends and having a longitudinal axis, the suture material emplaced in said hollow shaft; the free suture thread portion of said loop entering said hollow shaft through an opening provided in the distal end of said shaft, said free suture thread portion extending up toward the proximal end of said shaft; a longitudinally shiftable actuating means mounted in said shaft, the proximal end of said actuating means essentially extending up to the proximal end of said shaft; and a knife attached to the distal end of said actuating means, said knife having a cutting edge adapted to cut said free suture thread portion.
Claim 2
Dependent Claim
133 words
Endoscopic loop and applying instrument, comprising: a pre-knotted loop of surgical suture material having a free suture thread portion; and an instrument having a hollow shaft with proximal and distal ends and having a longitudinal axis, the suture material emplaced in said hollow shaft; the free suture thread portion of said loop entering said hollow shaft through an opening provided in the distal end of said shaft, said free suture thread portion extending up toward the proximal end of said shaft; a longitudinally shiftable actuating means mounted in said shaft, the proximal end of said actuating means essentially extending up to the proximal end of said shaft; and a knife attached to the distal end of said actuating means, said knife having a cutting edge adapted to cut said free suture thread portion.
Claim 3
Dependent Claim
31 words
The instrument according to claim 1, characterized in that the proximal end of said actuating means is shaped as an actuating button and protrudes from the proximal end of said shaft.
Claim 4
Dependent Claim
22 words
The instrument according to claim 2, characterized in that the proximal end of said actuating means is covered by a safety cap.
Claim 5
Dependent Claim
28 words
The applying instrument according to claim 3, characterized in that before use said safety cap is connected to the proximal end of said shaft at a frangible section.
Claim 6
Dependent Claim
23 words
The instrument according to claim 3, characterized in that the end of said free suture thread portion is fixed at said safety cap.
Claim 7
Dependent Claim
25 words
The instrument according to claim 1, characterized in that the cutting edge of said knife extends essentially parallel to the longitudinal axis of said shaft.
Claim 8
Dependent Claim
39 words
The instrument according to claim 6, characterized in that said free suture thread portion is guided in the distal end of said shaft between a support and a channel extending essentially parallel to the longitudinal axis of said shaft.
