Abstract

A trocar for use with a surgical instrument. The trocar including; a proximal trocar head; a trocar shaft arranged on the trocar head, the trocar shaft is configured to receive an elongated shaft of the surgical instrument, and a positioning device provided on the proximal trocar head and being movable between retracted and extracted states relative to the trocar head, the positioning device being configured to position a distal end of the elongated shaft of the surgical instrument outside the trocar head in the extracted position.

Claims (36)

1 . A trocar for use with a surgical instrument, the trocar comprising:

a proximal trocar head;

a trocar shaft arranged on the trocar head, the trocar shaft is configured to receive an elongated shaft of the surgical instrument; and

a positioning device provided on the proximal trocar head and being movable between retracted and extracted states relative to the trocar head, the positioning device being configured to position a distal end of the elongated shaft of the surgical instrument outside the trocar head in the extracted position;

wherein the positioning device is a telescopic tube section having an insertion opening for the elongated shaft of the surgical instrument; and

the telescopic tube section is at least partially received in an interior of the trocar shaft in the retracted state.

2 . The trocar according to claim 1 , wherein the telescopic tube section is arranged such that when the distal end of the elongated shaft of the surgical instrument is positioned outside the trocar head, a window of the distal end of the elongated shaft of the surgical instrument is accessible.

3 . The trocar according to claim 1 , wherein the positioning device is an elongated sleeve.

4 . The trocar according to claim 3 , further comprising a retaining device provided on the elongated sleeve for retaining the elongated sleeve on the trocar head.

5 . The trocar according to claim 1 , wherein the telescopic tube section is configured to be movable relative to the trocar shaft.

6 . The trocar according to claim 1 , wherein the telescopic tube section further comprising at least one end stop for limiting a movement of the telescopic tube section.

7 . The trocar according to claim 6 , further comprising a locking device at the at least one end stop for locking movement of the at least one telescopic tube section.

8 . The trocar according to claim 1 , wherein the telescopic tube section comprises a distal end and a proximal end and one or more connecting bars connecting the distal end and the proximal end.

9 . The trocar according to claim 8 , wherein the one or more connecting bars comprises a connecting bar extending linearly along a longitudinal direction of the telescopic tube section.

10 . The trocar according to claim 8 , wherein the one or more connecting bars comprises two or more connecting bars extending helically along a longitudinal direction of the telescopic tube section.

11 . The trocar according to claim 8 , wherein the telescopic tube section comprises an end stop for limiting a movement of the positioning device relative to a longitudinal direction of the trocar shaft, the end stop being provided on one or more of the distal end and the proximal end of the positioning device.

12 . The trocar according to claim 1 , wherein the trocar head has a greater size in a direction orthogonal to a longitudinal axis of the trocar shaft than a size of the trocar shaft in the direction orthogonal to the longitudinal axis of the trocar shaft.

13 . A surgical robot system with a surgical instrument comprising:

a robot for operating the surgical instrument; and

the trocar according to claim 1 for holding the surgical instrument.

14 . A surgical system comprising:

a surgical instrument having an elongated shaft; and

the trocar according to claim 1 for holding the surgical instrument.

15 . A trocar for use with a surgical instrument, the trocar comprising:

a proximal trocar head;

a trocar shaft arranged on the trocar head, the trocar shaft is configured to receive an elongated shaft of the surgical instrument; and

a positioning device provided on the proximal trocar head and being movable between retracted and extracted states relative to the trocar head, the positioning device being configured to position a distal end of the elongated shaft of the surgical instrument outside the trocar head in the extracted position;

wherein the positioning device is a telescopic tube section having an insertion opening for the elongated shaft of the surgical instrument;

the telescopic tube section comprises a distal end and a proximal end and one or more connecting bars connecting the distal end and the proximal end; and

the one or more connecting bars comprises two or more connecting bars extending helically along a longitudinal direction of the telescopic tube section.

16 . A surgical robot system with a surgical instrument comprising:

a robot for operating the surgical instrument; and

the trocar according to claim 15 for holding the surgical instrument.

17 . A surgical system comprising:

a surgical instrument having an elongated shaft; and

the trocar according to claim 15 for holding the surgical instrument.
