Description
Technical field
The present invention relates to electrosurgical medical technique with the apparatus field, specifically a kind of low-temperature plasma surgery systems.
Background technology
Clinic typically uses electric knife when being cut at present.Electric knife is that a kind of substitution mechanical operation knife is carried out
Organize cutting electrosurgical unit, it by active electrode tip produce high-frequency high-voltage current contacted with human body when to organize into
Row heating, occurs cell explosion or vaporizes, realize the separation and solidification to injected organism tissue, so as to play the mesh of cutting and hemostasis
's.
But electric knife is too high due to operationally procedures electrode temperature, generally 300 DEG C, therefore when being performed the operation
Fire damage to perienchyma is very big, is unfavorable for wound healing.In addition, the mechanical strength in order to ensure procedures electrode, therefore it is high
The procedures electrode of frequency electric knife can not be made thin or very thin, therefore otch is wider when cutting tissue, it is impossible to meet fine
The requirement of operation.
For this question patent number a kind of novel low temperature plasma operation is disclosed for 201410384714.7 patent
Device, although the device reduces the temperature of work to a certain extent, the problem of still having following several respects.
First, novel low temperature plasma operation device is made by reducing the width of bare electrode (i.e. the width of slit)
Energy is concentrated, so that power when reducing work, and then reduce the temperature of procedures electrode operationally, therefore the width of bare electrode
Spending (i.e. the width of slit) can not be too wide, is otherwise unfavorable for reducing temperature during procedures electrode work.But reduce the width of narrow slit
It is due to that the width of slit is narrow, worked although degree reduces temperature during procedures electrode work to a certain extent
The contact area of Cheng Zhongyu tissues is too small, therefore coagulating effectiveness is bad.
Second, temperature when novel low temperature plasma operation device works is 130 DEG C or so, although relative to electric knife
300 DEG C of operating temperature, is greatly reduced, but still can produce fire damage to surrounding tissue.
3rd, procedures electrode temperature is higher during due to work, operationally, the local organization on periphery is occurred carbon
Change, so as to stick on procedures electrode, need constantly to wipe procedures electrode during work, it is comparatively laborious.
The content of the invention
In view of the above-mentioned problems, the invention provides a kind of low-temperature plasma surgery systems, the system not only reduces heat waste
Wound, disclosure satisfy that the requirement of delicate procedure, and by setting coating on the surface of procedures electrode, reduce adhesion.
The technical scheme adopted by the invention to solve the technical problem is that：
A kind of low-temperature plasma surgery systems, including main frame, control pedal, negative plate and procedures electrode, described operation
Electrode includes plasma kinetic cutting electrode, and described plasma kinetic cutting electrode includes the first pole plate, the second pole plate and set
It is provided with the insulating barrier being placed between first pole plate and the second pole plate, described insulating barrier for conveying physiological saline
Infusion hole.
Further, described infusion hole is a plurality of, and a plurality of described infusion hole cuts electricity along the plasma kinetic
The width of pole is inline.
Further, described insulating barrier is formed using ceramic material.
Further, described insulating barrier is made using rigid plastics.
Further, the distance between first pole plate and the second pole plate described in the present embodiment 0.3-0.5mm.
Further, the first described pole plate and the second pole plate are respectively arranged with coating, described coating using tungsten sulfide,
Fluorine carbon or nano-silicon are made.
Further, described procedures electrode also includes being coated with tungsten needle electrode, and the tungsten needle of the tungsten needle electrode
Layer, described coating is made using tungsten sulfide, fluorine carbon or nano-silicon.
The beneficial effects of the invention are as follows：
1st, by setting the first pole plate and the second pole plate, and insulating barrier is set between the first pole plate and the second pole plate,
Infusion hole is set in insulating barrier, when plasma kinetic cutting electrode is contacted with tissue, before plasma kinetic cutting electrode
End forms low temperature plasma thin layer, by applying voltage to low temperature plasma thin layer, makes charged particle impinging tissue, interrupts
Molecular link, makes the tissue breakdowns such as protein, reaches the cutting purpose to tissue.In this course, due to the first described pole
The distance between plate and the second pole plate very little, can reach 0.3-0.5mm, and during operation by infusion hole in a steady stream not
The disconnected front end to plasma kinetic cutting electrode conveys physiological saline as electrolytic medium, therefore required operating voltage
Low, the heat of generation is small, and temperature during work is low, can be controlled in the range of 40 DEG C -70 DEG C by experiment work temperature, to week
The fire damage for enclosing tissue is small.
2nd, by setting infusion hole in insulating barrier, operationally, by infusion hole endlessly to plasma kinetic
The front end conveying physiological saline of cutting electrode, on the one hand there is provided electrolytic medium, on the other hand also plays the effect of cooling, enters
Reduce to one step the temperature during work of plasma kinetic cutting electrode.
3rd, while plasma kinetic cutting electrode operating temperature is ensured, plasma kinetic cutting electrode and group are increased
Contact area between knitting, improves the effect of blood coagulation.
4th, by the Surface coating coating in plasma kinetic cutting electrode and tungsten needle electrode, reduce in surgical procedure
Adhesion phenomenon.
