Abstract

An insertion device including a handle, a flexible shaft elongated at least in part with a movable distal portion controllable by a user interface, and a driving system for transforming actuation from the user interface to movement of the distal portion. The driving system has a housing leak-tightly connected to the shaft from one side and from the opposite side the housing is provided with the first detachable leak-tight fastener, whereas the handle is provided with the second detachable leak-tight fastener. A method of preparation for reuse of an insertion device in which the shaft is subjected to the treatment of at least one agent wherein subjected to disinfection is shaft with the driving system, whereas the handle with the user interface is detached from the driving system for the disinfection time.

Claims (19)

1 . An insertion device comprising:

a handle,

an elongated shaft at least in part flexible, having a movable distal portion controllable with a user interface, and

a driving system for transforming actuation from the user interface to a movement of the movable distal portion,

at least one cable member extending along the elongated shaft from the movable distal portion to the driving system, said at least one cable member having a first end and a second end, the first end being connected to the movable distal portion of the elongated shaft and the second end being connected to the driving system,

wherein the driving system is configured to convert the actuation from the user interface to a translatory motion of the at least one cable member,

wherein the driving system has a housing closed with a leak-tight partition and leak-tightly connected to the elongated shaft on one side, and

wherein the housing on the opposite side is provided with a first detachable leak-tight fastener, so that the driving system is detachable from the handle,

wherein the handle is provided with a second detachable leak-tight fastener configured to be leak-tightly connected to the first detachable leak-tight fastener,

wherein the driving system is configured to receive an actuation signal from the user interface via the leak-tight connection of the housing of the driving system with the handle when it is attached to the handle, and the at least one cable member is uninterrupted when the driving system is detached from the handle,

wherein the driving system constitutes a pull-push gear with an eccentric intermediate element, having on one side two cable members reciprocally attached and on the opposite side the eccentric intermediate element is engaged reciprocally with a first piston and a second piston,

wherein in the leak-tight partition two openings are provided, through which the first piston and the second piston protrude so that the first piston and the second piston are sealed in the two openings of the leak-tight partition by seals and they reciprocally affect the pull-push gear, whereas the user interface is a lever connected to a first pusher and a second pusher configured to push the first piston and the second piston, respectively.

2 . An insertion device according to claim 1 , wherein the movable distal portion is provided with an imaging device connected to a screen placed in the handle, by a connector of the housing provided in the housing of the driving system and a connector of the handle provided in the handle.

3 . An insertion device according to claim 2 , wherein the connector of the housing or the connector of the handle comprises touch-connectors.

4 . An insertion device according to claim 1 , wherein a light source is located in the housing of the driving system.

5 . An insertion device according to claim 1 , wherein the first detachable leak-tight fastener comprises a threaded connection with a gasket.

6 . An insertion device according to claim 1 , wherein the first detachable leak-tight fastener and the second detachable leak-tight fastener are complementary.

7 . An insertion device according to claim 1 , wherein the housing of the driving system is provided with a pneumatic connector.

8 . An insertion device according to claim 1 , wherein the housing of the driving system is provided with an optical connector.
