PROVIDING RAPID FEEDBACK FOR A USER OF A SURGICAL INSTRUMENT Russian patent published in 2019 - IPC A61B17/68 A61B17/72 A61B17/29 A61B17/295 

FIELD: medicine.

SUBSTANCE: method of providing the surgeon with feedback when stitching the tissues, according to which the suturing electric tool is provided. Sewing power tool comprises a handle with a power supply and an electric motor, a rod coupled to the handle, an end manipulator connected to the rod and equipped with a staple cartridge, a cassette sensor for determining the type of cassette in the end manipulator, a microprocessor connected to an electric motor, a data storage device connected to the microprocessor, and a data transmission device connected to the data storage device and the microprocessor. Microprocessor is designed so that to ensure operation of the tool, according to which the parameter of the electric motor is measured when the stapler is ejected by the stapling electric tool, the parameter of the electric motor is saved and the parameter of the electric motor is transmitted to the remote device. Microprocessor is further configured to transmit information on the identification data of the cartridge and the sensor of the cartridge to the remote device. Remote device is made with possibility to compare electric motor parameter with specified value, to notify the user that during the bracket installation, the motor parameters are beyond the preset value and provide recommendations on the cartridge selection based on the electric motor parameter comparison and the specified value. Setpoint is a known or assumed value based on a combination of the tool and the cartridge.

EFFECT: invention provides preventing staple formation when tissue is sutured, thereby preventing possible haemorrhage or divergence of the cross-linked tissue.
