MULTIFUNCTIONAL TOOL Russian patent published in 2019 - IPC A61B17/32 A61B17/3203 A61B18/04 A61B18/14 

FIELD: medicine.

SUBSTANCE: multifunctional tool for high-frequency surgical treatment of tissue comprises at least one fluid chamber for receiving a fluid; a temperature control device communicating with said at least one fluid chamber for warming, heating or evaporating a fluid, a temperature controller for controlling the temperature of the fluid, and at least one fluid outlet port arranged at a distal end of the multifunctional tool and communicating with said at least one fluid chamber. At least one fluid outlet port is arranged in an active electrode configured as a hollow conductor. Active electrode with the fluid outlet port protrudes beyond a distal end of a sheath of the multifunctional tool. Fluid outlet port at its proximal end is in fluid communication with the fluid chamber, and at the distal end is designed as a nozzle to create a jet of water or to dispense steam. Multi-function tool is configured to dispense a jet of water for cutting tissue from at least one fluid outlet port. System for high-frequency surgical treatment has at least one high-frequency generator for generating high-frequency treatment current, as well as for generating current for temperature control and has a multifunctional tool.

EFFECT: inventions ensure that there is no need for changing tools for various treatment steps and, in addition, they prevent such side effects as interference with peripheral devices, carbonisation and neuromuscular stimulation.
