摘要：
The utility model relates to the field of medicine, in particular to systems and devices for performing surgical interventions, and can be used in devices for tissue removal with minimally invasive interventions in urology and gynecology, in particular for the removal of uterine fibroids, prostate adenoma and other pathological tissues.The technical result of using a useful model is to increase the efficiency of the device by expanding its technological capabilities by simplifying the design.The technical result is achieved in that in a device for removing tissues with minimally invasive interventions comprising a cutting instrument for removing tissues made of an external stationary tube having a window on a lateral surface near the distal portion and an inner movable tube forming an aspiration channel and having a window on the side surface Near the distal part, coinciding with the outer tube window, while the windows on the outer fixed and inner movable tubes have cutting edges for cutting tissues, the inner movable tube is reciprocable within the outer fixed tube from a position in which the windows on the outer and inner tubes completely coincide with each other to a position where they do not completely coincide and the inner tube is drawn into the outer, wherein the cavity of the inner tube in the proximal part is connected to the vacuum suction through the waste collector, the inner movable tube being mechanically connected through an eccentric and gearbox with a motor disposed in the tool handle leading the inner tube into reciprocating motion, the engine being synchronized with the vacuum suction with a synchronization cable, and the device is turned on and off by the control pedal connected to the control unit, the device control unit has a microprocessor arguments, which controls the motor, the cutting tool for the removal of tissues located within the instrument channel of the endoscope, which has a liquid supply passage of the irrigation unit and the l
