Description

Bipolar electricity burns cutter

Technical field

This utility model relates to a kind of scalpel, and particularly a kind of bipolar electricity burns cutter.

Background technology

Electrosurgical normally utilizes 100KHz to 10MHz radio wave frequency (Radio Frequency, RF) electric current is crossed human body, impedance in tissue (Body Impedance) produces hyperpyrexia, and then disorganize, reaches the purpose of cutting and blood coagulation (Coagulation).

When carrying out the operation of one pole electricity burning cutter, the electric current that the electric knife generator is sent is responsible for collection by return electrode (Return Electrode), and is flowed back to original generator by patient body, so constitutes a complete loop, just can reach due function.From Fig. 1, can clearly see, the backflow bluff piece of return cable line (ReturnCable) 100 (Dispersive Electrode) 200 is attached on the human body, the electric current that provides at electric knife generator 300 reaches electrode (Active Electrode) front end that the one pole electricity burns cutter 500 by leader cable line (Active Cable) 400 with electric current, when electrode touches patient, and when the electric current density of contact point (Current Density) has been enough to cause local transconversion into heat, just can destroy tissue herein.By and large, electrosurgical depends primarily on three factors for the curative effect degree of tissue, i.e. the shape of electrode, the amplitude (Amplitude) of generator supply electric current and the time length of waveform (Wave Shape) and electrode contact tissue.

Though it is few that above-mentioned one pole electricity burning cutter makes wound lose blood in operation process, can reduce patient's transfusion volume, and speed is fast when the cutting affected part, can shorten the time that operation spends.But, the backflow bluff piece need be affixed on the patient body easy fire victim in operation process.
