Protective cover for a part of a medical device

1. A protective device for a handle of a medical device, the protective device comprising:

a first, flexible part; and

a second, rigid part, wherein the flexible part covers at least a grip area of the handle with the protective device arranged on the handle, and wherein the rigid part detachably meshes with a base area of the handle and the rigid part comprises at least one locking element for detachable fixation to the base area, the rigid part further comprising a thread or bayonet coupling which thread or bayonet coupling is configured for interaction with a thread or bayonet coupling in the base area in a positive-locking manner.

2. A protective device in accordance with claim 1 , wherein the rigid part further comprises turning assistance.

3. A protective device in accordance with claim 1 , wherein the rigid part further comprises an unlocking device at the rigid part, which said unlocking device is configured for detaching the locking element from a fixation in the base area of the handle.

4. A protective device in accordance with claim 3 , wherein the rigid part further comprises at least one predetermined breaking point associated in space with the unlocking device at the rigid part.

5. A protective device in accordance with claim 1 , wherein the rigid part is configured as a rigid, plate-shaped rigid part.

6. A protective device in accordance with claim 1 , wherein the thread or bayonet coupling of the rigid part is directly adjacent to an inner surface of the rigid part, the thread or bayonet coupling of the base area being directly adjacent to an outer surface of the base area.

7. A handle arrangement for a medical device, the handle arrangement comprising:

a handle comprising a base area and a grip area; and

a protective device, the protective device comprising:

a first, flexible part; and

a second, rigid part, wherein the flexible part covers at least the grip area of the handle with the protective device arranged on the handle, and the rigid part detachably meshes with the base area of the handle and the rigid part comprises at least one locking element for detachable fixation to the base area, the rigid part further comprising a thread or bayonet coupling which thread or bayonet coupling is configured for interaction with a thread or bayonet coupling in the base area in a positive-locking manner.

8. A handle arrangement in accordance with claim 7 , wherein the rigid part further comprises rotation gripping aids.

9. A handle arrangement in accordance with claim 7 , wherein the rigid part further comprises an unlocking device configured for detaching the locking element from a fixation in the base area of the handle.

10. A handle arrangement in accordance with claim 9 , wherein the rigid part further comprises at least one predetermined breaking point associated in space with the unlocking device.

11. A handle arrangement in accordance with claim 7 , wherein the rigid part is configured as a rigid, plate-shaped rigid part.

12. A handle arrangement in accordance with claim 7 , wherein the thread or bayonet coupling of the rigid part is directly adjacent to an inner surface of the rigid part, the thread or bayonet coupling of the base area being directly adjacent to an outer surface of the base area.

13. A handle arrangement in accordance with claim 12 , wherein the rigid part is configured to rotate relative to the base area such that rotation of the rigid part brings the thread or bayonet coupling of the rigid part in contact with the thread or bayonet coupling in the base area to connect the rigid part to the base area.

14. A handle arrangement in accordance with claim 7 , wherein the thread or bayonet coupling of the base part comprises a thread or bayonet coupling component, the thread or bayonet coupling component being directly adjacent to another portion of the base part.

15. A system comprising:

a protective device comprising a flexible part and a rigid part comprising at least one locking element; and

a handle of a medical device, wherein the handle comprises a grip area and a base area, and wherein the base area comprises a locking area configured for detachable fixation of the rigid part of the protective device at the handle with the locking area receiving the locking element of the protective device, the rigid part further comprising a thread or bayonet coupling which thread or bayonet coupling is configured for interaction with a thread or bayonet coupling in the base area in a positive-locking manner.

16. A system in accordance with claim 15 , wherein:

the locking area has a joining area, a catching area and a stop area between the joining area and the catching area and the stop area comprises a guide slope;

the joining area first receives the locking element during a connection of the protective device to the handle;

the guide slope deflects the locking element during the connection of the protective device to the handle and during a rotation of the rigid part relative to the base area of the handle; and

the locking element reaches the catching area from the guide slope during a further rotation of the rigid part and acts at the catching area to bring about the locking fixation of the rigid part at the base area of the handle.

17. A system in accordance with claim 15 , wherein the thread or bayonet coupling of the rigid part is directly adjacent to an inner surface of the rigid part, the thread or bayonet coupling of the base area being directly adjacent to an outer surface of the base area.

18. A system in accordance with claim 17 , wherein the rigid part is configured to rotate relative to the base area such that rotation of the rigid part brings the thread or bayonet coupling of the rigid part in contact with the thread or bayonet coupling in the base area to connect the rigid part to the base area.

19. A system in accordance with claim 15 , wherein the thread or bayonet coupling of the rigid part is directly adjacent to an inner surface of the rigid part, the thread or bayonet coupling of the base area being directly adjacent to an outer surface of the base area.

20. A system in accordance with claim 19 , wherein the thread or bayonet coupling of the base part comprises a thread or bayonet coupling component, the thread or bayonet coupling component extending radially outward from another portion of the base part.
