Abstract

A laparoscope with an elongated rigid shaft, including an observation device at its distal end and a handle body at its proximal end, with a main body disposed at a distance from the handle body and connected thereto by a connecting piece, wherein the connecting piece is designed such that the position thereof can be adjusted.

Claims

1. A laparoscope with an elongated rigid shaft, comprising an observation device at its distal end and a handle body at its proximal end, with a main body disposed at a distance from the handle body and connected thereto by a connecting piece, wherein the connecting piece is designed such that the position thereof can be adjusted.

2. The laparoscope according to claim 1, wherein the connecting piece comprises a bending means that allows a reversible angle adjustment of the connecting piece or the parts of the connecting piece adjacent to the bending means in relation to each other when actuating forces are applied that will not destroy, but that are greater than the self-supporting force as well as the forces present at the bending means if forces for the manipulation of the laparoscope are applied.

3. The laparoscope according to claim 2, wherein the bending means is designed as a joint.

4. The laparoscope according to claim 2, wherein the bending means is designed as a connecting piece that is bendable at least in some areas.

5. The laparoscope according to claim 2, wherein the main body is formed as a handle at least in some areas.

6. The laparoscope according to claim 1, wherein the connecting piece is designed not to be self-supportingly bendable.

7. The laparoscope according to claim 6, wherein the connecting piece is of a length that allows the depositing of the main body next to the port in the application position of the laparoscope in a laparoscopic port.

8. The laparoscope according to claim 1, wherein the observation device is designed as an image sensor located at the distal end of the shaft, the same being connected by means of continuous electric lines via the shaft and the connecting piece.

9. The laparoscope according to claim 8, wherein the image sensor is designed rotatably and is in adjustment connection with an actuating member located on the handle body and actuatable from the outside.

10. The laparoscope according to claim 9, wherein the actuating member is designed as a ring rotatably positioned on the handle piece and being rotatable around the axis of the handle piece.

11. The laparoscope according to claim 1, further comprising an optical fibre bundle serving for illumination, the optical fibre bundle being routed through the shaft and the connecting piece.

12. The laparoscope according to claim 1, wherein the main body comprises electric and/or electronic components.

13. The laparoscope according to claim 12, further comprising at least one switch to be activated from the outside, the at least one switch being located on the main body.

14. The laparoscope according to claim 8, further comprising a cable containing an electric and/or optical fibre line leading away from the main body.

15. The laparoscope according to claim 4, wherein the connecting piece is designed as a goose neck.

16. The laparoscope according to claim 15, wherein the observation device is designed as an image sensor located at the distal end of the shaft, the same being connected by means of continuous electric lines via the shaft and the connecting piece and the electric lines are routed through the lumen enclosed by the goose neck.

17. The laparoscope according to claim 15, further comprising an optical fibre bundle serving for illumination, the optical fibre bundle being routed through the shaft and the connecting piece wherein the optical fibres are located within an annular space surrounding the goose neck, the same being formed between the outer surface of the goose neck and a radially distanced outer protective sleeve.

18. The laparoscope according to claim 17, wherein the goose neck is radially surrounded by an inner protective sleeve, and in that the optical fibres are located between this inner protective sleeve and the outer protective sleeve.

19. A laparoscope system with a port designed for the simultaneous passage of several shafts and with a laparoscope according to claim 1.

20. The laparoscope system according to claim 19, wherein a surgical shaft instrument is provided.
