Trocar System
First Claim
1. A trocar system, comprising:
- a trocar, having an optical channel that extends coaxially inside the trocar for receiving an optical unit, the trocar having a hollow transparent distal tip that can be observed from the interior by the optical unit,wherein a distal working end of an instrument is configured at the distal tip,wherein the instrument includes at least two working parts that can be moved relative to each other,wherein a first of the at least two working parts is an integral component of the distal tip and the second of the at least two working parts is movably supported on the distal tip,wherein an actuating channel is configured on the trocar and leads from a proximal end of the trocar to the distal tip, and in thatwherein an actuating element is received in an axially displaceable manner inside the actuating channel, and a proximal end of the actuating element is guided out from a proximal end of the actuating channel, and the distal end of the actuating element engages on the second working part in order to move the second working part.

Abstract
A trocar system, comprising a trocar, having an optical channel extending coaxially in the trocar for receiving an optical unit, and a hollow transparent distal tip of the trocar, which can be observed from the interior. The distal working end of an instrument having two working parts movable relative to one another is formed on the distal tip, wherein a first working part is an integral component of the tip and the second working part is mounted movably on the tip, wherein an actuating channel is constructed in the wall of the trocar surrounding the optical channel, which channel extends axially parallel from the proximal end of the trocar into the distal tip thereof, and wherein an actuating element is received in the actuating channel such as to be axially displaceable.
