Abstract

A device and an associated method for identifying a collision in a medical instrument are provided. The device includes a carrier module of the medical instrument, a housing cladding module that is detachably connected to the carrier module at at least one connection site, and at least one switching element arranged on the carrier module at a distance from the connection site. A partial portion of the housing cladding module has a spring-like flexible design in order to be pressed in the direction of the switching element during a collision with an object.

First claim

The invention claimed is:

1. A device for identifying a collision in a medical instrument, the device comprising:
a carrier module;
a housing cladding module that is detachably connected to the carrier module at a connection site;
a switching element that is arranged on the carrier module adjacent to an end of the carrier module at a distance from the connection site; and
a portion of the housing cladding module positioned between the connection site and an end of the housing cladding module adjacent to the switching element, the portion of the housing cladding module having a spring-like flexible design configured to be pressed in a direction of the switching element during a collision with an object,
wherein the device is configured to move from an open position to a closed position upon collision with the object, wherein the end of the housing cladding module adjacent to the switching element does not contact the switching element in the open position, and wherein the end of the housing cladding module adjacent to the switching element contacts the switching element in the closed position.

2. The device of claim 1 , further comprising a bending line in the housing cladding module, the bending line being configured to bend the portion along the bending line during the collision.

3. The device of claim 2 , wherein the bending line is formed by a thin point of the housing cladding module.

4. The device of claim 1 , further comprising a switching lug located in the portion of the housing cladding module and configured to actuate the switching element.

5. The device of claim 4 , wherein the switching lug is at a distance from the switching element in the open position, as a result of which a switching path is formable.

6. The device of claim 1 , wherein the switching element comprises a microswitch, the microswitch being configured to stop a movement of the carrier module.

7. The device of claim 1 , wherein the housing cladding module is screwed to the carrier module at the connection site.

8. The device of claim 1 , wherein the housing cladding module is a thermoplastic polymer.

9. The device claim 1 , wherein the medical instrument is a C-arm x-ray instrument.

10. A medical instrument comprising:
a device for identifying a collision in a medical instrument, the device comprising:
a carrier module;
a housing cladding module that is detachably connected to the carrier module at a connection site;
a switching element that is arranged on the carrier module adjacent to an end of the carrier module at a distance from the connection site; and
a portion of the housing cladding module positioned between the connection site and an end of the housing cladding module adjacent to the switching element, the portion of the housing cladding module having a spring-like flexible design configured to be pressed in a direction of the switching element during a collision with an object,
wherein the device is configured to move from an open position to a closed position upon collision with the object, wherein the end of the housing cladding module adjacent to the switching element does not contact the switching element in the open position, and wherein the end of the housing cladding module adjacent to the switching element contacts and the switching element in the closed position.

11. The medical instrument of claim 10 , wherein the device further comprises a bending line in the housing cladding module, the bending line being configured to bend the portion along the bending line during the collision.

12. The medical instrument of claim 11 , wherein the bending line is formed by a thin point of the housing cladding module.

13. The medical instrument of claim 10 , wherein the device further comprises a switching lug located in the portion of the housing cladding module and configured to actuate the switching element.

14. The medical instrument of claim 13 , wherein the switching lug is at a distance from the switching element in the open position, as a result of which a switching path is formable.

15. The medical instrument of claim 10 , wherein the switching element comprises a microswitch, the microswitch being configured to stop a movement of the carrier module.

16. The medical instrument of claim 10 , wherein the housing cladding module is screwed to the carrier module at the connection site.

17. The medical instrument of claim 10 , wherein the housing cladding module is a thermoplastic polymer.

18. The medical instrument of claim 10 , wherein the medical instrument is a C-arm x-ray instrument.

19. A method for identifying a collision in a medical instrument with a device, the device comprising a carrier module, a housing cladding module that is detachably connected to the carrier module at a connection site, a switching element that is arranged on the carrier module adjacent to an end of the carrier module at a distance from the connection site, and a portion of the housing cladding module positioned between the connection site and an end of the housing cladding module adjacent to the switching element such that the portion of the housing cladding module has a spring-like flexible design in order to be pressed in a direction of the switching element during a collision with an object, the method comprising:
pressing the portion of the housing cladding module in a direction of the switching element as a result of the collision with the object, wherein the device moves from an open position to a closed position upon collision with the object, wherein the end of the housing cladding module adjacent to the switching element does not contact the carrier switching element in the open position, and wherein the end of the housing cladding module adjacent to the switching element contacts the switching element in the closed position; and
triggering, by the switching element, a collision signal.

20. The method of claim 19 , wherein the medical instrument is a C-arm x-ray instrument.
