Description
Technical field
The present invention relates to a kind of electric discharge device, specifically, relate to a kind of high pressure pulse discharge biological tissue ablation device.
Background technology
At present, high pressure pulse discharge can produce high-octane plasma, these plasmas will produce to tissue the effect melted when running into the biological tissue of pathological changes, in the process that electric discharge is melted, because the energy of plasma is very high, around the temperature of heavy particle is lower, and the temperature of whole ablation procedure is no more than 60 DEG C, therefore can not damage normal healthy cell, and have no side effect.When pathological changes occurs in biological tissue, traditional method is the patterning method based on scalpel, and during cutting, otch can produce a large amount of blood, makes the incision visual field fuzzy, is unfavorable for the carrying out of performing the operation, and otch is not easy more greatly healing.
Summary of the invention
The object of the invention is the shortcoming for prior art, a kind of device of high pressure pulse discharge biological tissue ablation is provided.
Technical scheme of the present invention is: a kind of high pressure pulse discharge biological tissue ablation device, it is characterized in that: comprise high voltage power supply, sparking electrode, control circuit, impedance detection instrument and display screen, described high voltage power supply is connected with sparking electrode with control circuit successively, described impedance detection instrument is connected with control circuit, be positioned over tissue place to be ablated, described sparking electrode is crosspointer electrode.
Preferably, the effective voltage value of described high-voltage pulse power source is 175 ~ 330V, and frequency is 100KHz.
Preferably, described sparking electrode be silver-coated electrode.
The present invention's beneficial effect is compared with prior art:
This high pressure pulse discharge biological tissue ablation device comprises high voltage power supply, sparking electrode, control circuit, impedance detection instrument and display screen, realize the effective voltage value of high-voltage pulse power source being the adjustment of 175 ~ 330V by control circuit, impedance detection instrument is connected with control circuit, be positioned over tissue place to be ablated, while melting, the moment detects the resistance value of tissue, and tissue impedance being sent to display screen display, sparking electrode is silver-coated electrode, and discharge process unharmful substance produces.
Accompanying drawing explanation
