Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 156 words
Laparoscopic instrument for looping hollow organs and for the application of endoligatures, particularly in the abdominal cavity, comprising an instrument tube (4), insertable through a trocar cannula (14) with a distal end into the abdominal cavity, and a gripping tool (16) longitudinally movable in the instrument tube and which can be slid out of the distal end and which serves to grip a ligature binder characterised in that it comprises a spiral spring element (8) which, under loading, is guided in the unrolled state in the longitudinal direction of the instrument tube and can be slid by means of a slide mechanism (6) out of the distal end, the spiral spring element being dimensioned in such a way that its resiliency returns the slid-out end with one winding to the distal end of the instrument tube and in that the gripping tool (16) serves to grip the ligature binder carried along by the spiral spring element.
Claim 2
Dependent Claim 29 words
Laparoscopic instrument according to claim 1, characterized in that the spiral spring element (8) is produced from a superelastic material strip, which forms a winding in the unloaded state.
Claim 3
Dependent Claim 20 words
Laparoscopic instrument according to claim 2, characterized in that the spiral spring element (8) is produced from a nickel-titanium alloy.
Claim 4
Dependent Claim 56 words
Laparoscopic instrument according to one of the preceding claims, characterized in that the spiral spring element (8) in the instrument tube is held unrolled in a tubular hollow body, which is displaceably guided in the instrument tube, it being possible to slide the spiral spring element out of the hollow body through the slide mechanism (6).
Claim 5
Dependent Claim 21 words
Laparoscopic instrument according to one of the preceding claims, characterized in that the gripping tool is constructed as gripping forceps (16).
Claim 6
Dependent Claim 28 words
Laparascopic instrument according to one of the preceding claims, characterized in that at its distal end the spiral spring element has a device for holding the ligature binder.
Claim 7
Dependent Claim 22 words
Laparoscopic instrument according to claim 6, characterized in that the device for holding the ligature binder is formed by a hook-like bend.
Claim 8
Dependent Claim 24 words
Laparoscopic instrument according to claim 6, characterized in that the device for holding the ligature binder is formed by a laterally bent clamping device.
Claim 9
Dependent Claim 25 words
Laparoscopic instrument according to one of the preceding claims, characterized in that the gripping tool is constructed as a hook for gripping a ligature binder.
Claim 10
Dependent Claim 28 words
Laparoscopic instrument according to one of the preceding claims, characterized in that a clip applicator, which can be slid out, can be introduced into the instrument tube (4).
Claim 11
Dependent Claim 26 words
Laparoscopic instrument according to one of the preceding claims, characterized in that a longitudinally displaceable closing forceps can also be introduced into the instrument tube (4).
