Abstract

Holding device for holding a manually operated medical device in place, comprising: a connector arranged to connect the holding device to a positioning apparatus; a clamp member arranged to clamp the medical device, wherein the clamp member is moveable between a locking position wherein the medical device is clamped and a moving position wherein the medical device is moveable with respect to the holding device; a joint assembly arranged to allow movement between the clamp member and the connector, wherein the joint assembly is moveable between a moving position wherein the clamp member is moveable with respect to the connector and a locking position wherein movement between the clamp member and the connector is prevented, and; an actuator for moving both the joint assembly and the clamp member between the moving positions and the locking positions.

Claims

1. Holding device for holding a manually operated medical device in place, comprising:

a connector arranged to connect the holding device to a positioning apparatus;

a clamp member arranged to clamp the medical device, wherein the clamp member is moveable between a locking position wherein the medical device is clamped and a moving position wherein the medical device is moveable with respect to the holding device;

a joint assembly arranged to allow movement between the clamp member and the connector, wherein the joint assembly is moveable between a moving position wherein the clamp member is moveable with respect to the connector and a locking position wherein movement between the clamp member and the connector is prevented, and;

an actuator for moving both the joint assembly and the clamp member between the moving positions and the locking positions.

2. Holding device according to claim 1, wherein at least one of the clamp member and the joint assembly is arranged to move between the positions due to movement of the other one of the joint assembly and the clamp member between the positions.

3. Holding device according to claim 1, wherein the clamp member and at least one part of the joint assembly are formed integrally in a holding body, wherein the actuator is arranged to move the holding body between a moving and a locking position for moving the clamp member and the joint assembly between the moving and the locking positions.

4. Holding device according to claim 1, wherein the actuator comprises a manipulator allowing the surgeon to operate the actuator, wherein the manipulator extends at a distance from the actuator.

5. Holding device according to claim 4, wherein the holding body is at least partially manufactured from a resilient material, wherein the holding body is preferably pre-stressed towards the moving or the locking position of the holding body.

6. Holding device according to claim 1, wherein the joint assembly comprises a protruding member and a receiving member for receiving the protruding member, wherein the receiving member is substantially complementary to the protruding member, wherein the actuator is arranged to induce movement between the receiving member and the protruding member for moving between the locking and the moving position.

7. Holding device according to claim 6, wherein the protruding member has a substantially cylindrical, conical or spherical shape.

8. Holding device according to claim 5, wherein the holding body comprises a channel for receiving the medical device, wherein an inner surface of said channel forms said clamp member, wherein an outer surface of the holding body forms the protruding member of the joint assembly, and wherein the actuator is arranged to deform the holding body for moving the holding body between the moving and the locking positions.

9. Holding device according to claim 8, wherein the holding body comprises a plurality of segments extending radially from said channel.

10. Holding device according to claim 8, wherein the actuator is arranged to modify the diameter of the receiving member of the joint assembly for deforming the holding body for moving both the joint assembly and the clamp member between the locking positions and the moving positions.

11. Holding device according to claim 8, wherein the holding body is formed integrally with a guiding tube, in particular a trocar, wherein the clamping member forms an inner wall of said guiding tube.

12. Holding device according to claim 3, wherein the holding body is substantially U-shaped, wherein the two legs of said U-shaped holding body form the clamp members for clamping the medical device there between.

13. Holding device according to claim 12, wherein the clamp members comprise clamping shoes, wherein the clamping shoes are arranged to clamp the medical device in the locking position around a part of the perimeter of said medical device.

14. Holding device according to claim 12, wherein the clamping member is provided moveable on the holding body, in particular rotatable.

15. Holding device according to claim 12, wherein the part of the joint assembly extends in the base of the U-shaped holding body.

16. Holding device according to claim 12, wherein the receiving member of the joint assembly is provided on the holding body, wherein the actuator is arranged to modify the shape of the receiving member.

17. Holding device according to claim 12, wherein the actuator is arranged to translate the receiving member and the protruding member of the joint assembly for moving said member between the moving and the locking position.

18. Holding device according to claim 12, wherein the clamp member is arranged to clamp the medical device in a guiding tube, in particular a trocar, adapted for use with the holding device.

19. Holding device according to claim 18, wherein the clamp member is formed integrally with the guiding tube, wherein the inner wall of said guiding tube is moveable for clamping said medical device.

20. Guiding tube, in particular a trocar, for use with the holding device according to claim 1, wherein a part of the wall of the tube is arranged to receive the clamp member.

21. Guiding tube according to claim 20, wherein the tube is provided with at least one opening for receiving the clamp member.

22. Guiding tube according to claim 20, wherein the tube is provided with a moveable wall for cooperation with the clamp member.

23. Method for holding a manually operated medical device in place using a holding device according to claim 1.
