Claim Text:
1. A trocar system, comprising: a rigid trocar, having an optical channel that extends coaxially inside the trocar for receiving an optical unit, the trocar having a hollow transparent distal tip in the shape of a cone and through which an area outside of the distal tip can be observed from an 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 separate from the distal tip and disposed on the exterior of the distal tip and is movably supported on the distal tip, wherein the hollow transparent distal tip remains closed when the second of the at least two working parts is moved, wherein an actuating channel is configured on the trocar and leads from a proximal end of the trocar to the distal tip, and wherein 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, and wherein a working channel is provided in a wall of the trocar and the working channel opens at the distal tip and exterior to the distal tip.
