FIELD: medicine.
SUBSTANCE: medical device control lever with an elongated body, a distal assembly that located distally relative to the elongated body and having an adjustable configuration. At that, the medical device comprises a pull-out element extending through the elongated body and the distal assembly. The control handle comprises a housing and an actuator assembly. The housing has an outer surface with a groove formed thereon. The actuator assembly comprises: a disk controller, rotatable by the user; a coil with a barrel, inserted into the through hole of the housing; a lock washer mounted on the barrel; at least one washer for friction, locayed on the barrel; and a fastener located on the barrel and intended to create a compressive force acting on the washer, which creates friction. The coil has a drum on which the pull-out element is wound. The lock washer is rotationally coupled with the disk controller to transmit rotary motion from the disk controller to the barrel. The lock washer has a protrusion moving in the groove to guide lock washer movement. A catheter comprises: an elongated body; a distal assembly with adjustable configuration; a pull-out element extending through the elongated body and the distal assembly; and the previously mentioned control handle.
EFFECT: invention allows more precise control of the catheter position and direction.
