CONTROL HANDLE FOR MEDICAL DEVICE WITH INDEPENDENT SELF-LOCKING ACTUATORS FOR ADJUSTMENT USING PULL WIRE Russian patent published in 2017 - IPC A61B18/14 A61M25/00 A61M25/01 A61M25/08 

FIELD: medicine.

SUBSTANCE: control handle for a medical device, which has at least the first function and the second function controlled by the user. The medical device further comprises at least the first pull wire and the second pull wire to control the first and the second control functions. Control handle comprises: a housing including the first and the second portions; the first actuating unit and the second actuating unit, independently rotating around the common axis of rotation. The first actuating unit comprises the first actuator, an arm rotating around the said common axis of rotation, and the first bore. The first actuator and the arm are rotatably connected by the first bore. The arm has at least one pulley. The first pull wire is engaged with at least one said pulley. The second actuating unit comprises the second actuator and the second bore with a coil. Rotation of the first actuator results in arm rotation moving at least one pulley to pull the first wire to control the first function of the medical device, while rotation of the second actuator results in coiling of the second pull wire serving to control the second function of the medical device. A catheter comprises: an elongated body; a distal assembly with adjustable configuration; the first and the second pull wires extending through the elongated body; the third tensioning wire extending through the elongated body and the distal assembly; and the previously mentioned control handle.

EFFECT: invention allow more precise control of the catheter position and direction.
