TISSUE REMOVAL DEVICE Russian patent published in 2020 - IPC A61F9/07 

FIELD: medicine.

SUBSTANCE: device for use in removing tissue from a body organ is presented. Device comprises a portable probe device, a rotating motor device and a connecting unit configured to be connected by a detachable method of a portable probe device to a rotating propulsion device. Portable probe device is disposable and comprises a body having a proximal and distal ends, a rotatable cutting tool extending in a distal direction from the distal end of the body and configured to cut and remove tissue during rotation, and a transmission assembly extending in the housing between the proximal and distal ends and configured to transmit a torque to the rotatable cutting tool. Connecting assembly is configured to provide interaction between rotary propulsion device and transmission assembly to thereby provide controlled rotation of cutting tool and removal of fabric. According to some embodiments of realization device contains control unit for control of device operation, besides, control unit contains activation mechanism for activation of rotary cutting tool and a controller configured to control the activation mechanism to generate a single fixed activation signal with a certain intensity and duration for a given time interval, thus limiting operation of cutting tool during said time interval defined only by said single activation signal.

EFFECT: group of inventions refers to medical devices and, in particular, to surgical instruments.
