Endoscopic system

1. An endoscopic system comprising:

a flexible endoscope with;

an elongate, flexible shaft,

a regulator part, and also

an operating part which can be placed on or pushed onto the shaft and which has at least one control element,

wherein the endoscopic system comprises;

a shaft stop,

which can be secured on a patient support, and

which has a locking mechanism, controllable by the at least one control element, for locking the shaft against movement in a longitudinal direction of the shaft;

wherein the at least one control element is a shaft sensor, and the locking mechanism can be controlled by the shaft sensor in such a way that, when a signal of the shaft sensor indicates that the operating part is not placed on or pushed onto the shaft, the shaft is locked.

2. The endoscopic system according to claim 1 , wherein the operating part has a half-shell for receiving the shaft.

3. The endoscopic system according to claim 1 , wherein the shaft sensor is a pressure sensor.

4. The endoscopic system according to claim 1 , wherein the at least one control element is an operating element for manually controlling the locking mechanism.

5. The endoscopic system according to claim 4 , wherein the shaft sensor, the operating element and the locking mechanism are connected in such a way that the locking mechanism can be controlled by the operating element only when the signal of the shaft sensor indicates that the operating part is placed on or pushed onto the shaft.

6. The endoscopic system according to claim 1 , wherein the operating part has at least one operating element for controlling an angle of a distal end portion of the shaft.

7. The endoscopic system according to claim 1 , wherein the operating part is designed to control endoscopic work instruments, or a further operating part is provided to control endoscopic work instruments.

8. The endoscopic system according to claim 1 , wherein the locking mechanism can be controlled via a wireless connection.

9. The endoscopic system according to claim 1 , wherein the shaft stop has a through-opening for holding the shaft.

10. The endoscopic system according to claim 1 , wherein the shaft stop has a tube holder for holding a shaft protection film.

11. The endoscopic system according to claim 1 , wherein the regulator part comprises at least one connection for supplying the endoscope, and/or at least one drive coupling for drives that adjust an angle of a distal end portion of the shaft of the endoscope.

12. The endoscopic system according to claim 1 , wherein the shaft is connected to the regulator part so as to be rotatable about a longitudinal axis of the shaft.

13. The endoscopic system according to claim 1 , wherein the shaft of the endoscope includes a shaft protection film on an outer portion of the shaft, and the shaft stop includes a tube holder;

the shaft protection film is pulled against the tube holder and is removable from the shaft when the shaft passes through the shaft stop in a direction toward a patient.

14. The endoscopic system according to claim 13 , wherein the shaft protection film reattaches to the outer portion of the shaft when the shaft passes through the shaft stop in a direction opposite the patient.

15. The endoscopic system according to claim 13 , wherein the shaft stop includes a bow configured to secure the shaft protection film to the tube holder.

16. The endoscopic system according to claim 1 , wherein the locking mechanism for locking the shaft includes a first plate on a first side of the shaft and a second plate on a second side of the shaft;

the first plate is moveable in a direction towards the second plate locking the shaft against movement, and when the first plate is moveable in a direction opposite the second plate the shaft is able to pass through an opening between the first plate and the second plate.
