SELF-LOCKING DRIVE CONTROL HANDLE OF MEDICAL DEVICE WITH MECHANISM FOR COUPLING WITH CAM DRIVE Russian patent published in 2017 - IPC A61B1/00 A61M25/00 A61M25/01 A61M25/08 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment, namely to control handle for medical devices, in particular to control handle with multiple mechanisms for managing plurality of extending wires, as well as to catheter with such handle. Control handle for medical device with at least first structural element controlled by user and at least first extraction element for control of first structural element comprises housing and first drive unit. First drive unit comprises: first actuating element, shaft, roller lever and clutch gear. Shaft length determines first rotation axis, first actuating element is installed on shaft and it is made with possibility of displacement in plane, in fact perpendicular to shaft. Roller lever is installed on shaft and is connected to it with possibility of rotation, wherein roller lever has possibility of activation of first traction element during shaft rotation. Coupling mechanism is made with possibility of engagement and disengagement. Clutch gear has friction disk and friction creating surface. Friction disk is installed on shaft and is connected to it with possibility of rotation. Friction disk is in contact with friction creating surface in engaged state and does not contact friction creating surface in disengaged state of clutch mechanism. Shaft is made with possibility of translational movement along its length under action of first actuating element, when first actuating element is removed from plane for disengagement of clutch mechanism, as well as with possibility of rotary movement under action of first actuating element, when clutch gear is in disengaged state. Catheter is configured with possibility of mapping and/or ablation, catheter comprises elongated body; intermediate flexible section located distally to catheter body; said control lever located proximally to catheter body; and at least first extraction element passing between control handle and intermediate flexible section.

EFFECT: invention enables more accurate control of position and direction of catheter.
