<p>PCT No. PCT/EP95/03525 Sec. 371 Date Mar. 13, 1997 Sec. 102(e) Date Mar. 13, 1997 PCT Filed Sep. 8, 1995 PCT Pub. No. WO96/08204 PCT Pub. Date Mar. 21, 1996The invention concerns a surgical instrument whose distal end region is to be introduced or inserted by a puncture into a cavity of a patient's body. The surgical instrument has an outer trocar sleeve (1) and a trocar mandrel (2) which can be inserted in the latter and is guided in a sliding manner. When slid into an end position, the distal tip (4) of the trocar mandrel (4) projects beyond the end region (3) of the trocar sleeve (1), which end region is inclined relative to the longitudinal axis of the sleeve. In order to keep the distance between the trocar mandrel tip (4) and the distal end (6) of the trocar sleeve (1) as small as possible and to reduce the risk of injury to the patient when the surgical instrument is inserted by a puncture, it is proposed according to the invention that the trocar mandrel tip (4) is eccentric relative to the longitudinal axis of the trocar mandrel and is disposed in the region of the distal end (6) of the trocar sleeve (1) facing the patient.</p> |
