Trocar system
First Claim
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, andwherein 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, andwherein 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.

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.

13. A trocar system, comprising:
-
a rigid trocar with a hollow transparent distal tip; an optical channel that extends inside the rigid trocar for receiving an optical unit and terminates inside the hollow transparent distal tip; a working channel in a wall of the rigid trocar that opens proximate to the hollow transparent distal tip and exterior to the hollow transparent distal tip; an instrument located at the hollow transparent distal tip, the instrument including a plurality of working parts that can be moved relative to each other, wherein a first working part of the plurality of working parts is an integral component of the hollow transparent distal tip and a second working part of the plurality of working parts is located exterior to the hollow transparent distal tip, separate from the hollow transparent distal tip, and movably supported on the hollow transparent distal tip such that the hollow transparent distal tip remains closed when the second working part of the plurality of working parts is moved; an actuating channel leading from a proximal end of the rigid trocar to the hollow transparent distal tip; and an axially displaceable actuating element inside the actuating channel that engages the second working part of the plurality of working parts to move the second working part of the plurality of working parts. - View Dependent Claims (14, 15, 16, 17, 18)
