Description

The utility model relates to the field of medicine and is intended for performing cosmetic surgery to remove hair and coagulating tissue on the skin or other parts of the human body.

Known high-frequency hirsphic device for cutting and / or coagulation of biological tissue EPO patent application No. 0316469, which contains an automatic closed loop for adjusting the output voltage, a voltage converter combined with electrical insulation in the form of an isolation transformer connected to the output, nests consumer electrical circuit. The output signal of the circuit is supplied to a control amplifier, to which a sensor signal of a predetermined value is also supplied. The output signal from the control amplifier is fed to an electronically controlled section of the circuit, so that the operating voltage of the amplifier always has such a value that the output voltage at the output sockets. The disadvantage of this device is that it is complex and expensive, in addition, it cannot be used for hair removal, since the protruding part of the coagulation head has a diameter of at least 0.3 mm.

Closest in technical essence and achievable

the effect is a high-frequency coagulation device for surgical purposes, the Federal Republic of Germany patent No. 3838840 which contains

 1st.

a coagulant-bottomed head with a heating and passive part, a temperature sensor, of which q.c. is installed in the coagulation head, and.) angular - at a distance from the first temperature sensor in the passive part of the coagulation head. The disadvantage of this device is that it is intended for coagulation of internal organs to perform cosmetic operations to remove hair, in addition, it is expensive, complex, unreliable, which is especially important in conditions of its widespread use in cosmetic hospitals, in addition, the presence of a closed loop and feedback on the signal, as well as work at a relatively low frequency, leads to a significant increase in the time to enter the local heating mode.

The purpose of the utility model is to expand the functionality, but while simplifying the device and increasing its reliability, as well as reducing its cost, which is especially important when it is widely used in cosmetic operations.

This goal is achieved by the fact that in the known high-frequency coagulation device for surgical purposes, containing a high-frequency generator, voltage stabilizer, power regulator, an electrode with a holder, an input transformer is introduced, a rectifier, the inputs of which are connected to the output o (transformer branch, breaker, respectively) circuit, a smoothing filter, and one output of the rectifier through a circuit breaker is connected to a single input of the stabilizer.

The action of a high-frequency electroepilator-coagulator is based on coagulation of biological tissue due to local heating with a high-frequency electric current. The input transformer (I) lowers the mains voltage to 25 V. The rectifier (2) provides rectification, voltage stabilization and the possibility of its regulation in the range from 3 to 2 V. A high-frequency generator (6), which is an oscillating circuit, converts a constant voltage into alternating s frequency 2-2.5 MPd. The high-frequency generator (6) has two outputs for operating in hair removal or coagulation mode. Corresponding electrodes with a holder are connected to these conclusions. The power to the high-frequency generator is supplied only when closed

at

circuit breaker (mounted) with the foot pedal closed.

When the pedal is pressed, a high-frequency signal appears on the electrode and the corresponding operation can be performed. The handle of the power regulator sets the required position, the required power is determined on the basis of preliminary experience and the characteristic features of the patient.

The technical and economic advantage of the utility model is that a high-frequency epilator-coagulator

It has a simplified scheme, increased reliability with enhanced functionality - it can work in the mode of hair removal and coagulation. Director of ShP Regul
