Description
Technical field
The present invention relates to a kind of high frequency electric knife electrode, particularly relate to a kind of electrode that can alleviate surface texture adhesion.
Technical background
High frequency electric knife is that a kind of traditional operation cutter that replaces carries out the Electrosurgical instrument of tissue cutting, and it is by main frame and electricity
Pole pen composition.During work, the high-frequency alternating current that main frame produces, through the electrode of electrode anterior end of pen and the tissue of electrode contact,
Negative plate flows back to main frame；High-frequency alternating current flows through tissue can produce huge heat, and then realizes the separation to tissue and coagulate
Gu, thus reach cutting and the purpose of hemostasis.Compared to traditional mechanical formula scalpel, high frequency electric knife cutting speed is fast, hemostasis effect
The best, and otch is had certain bactericidal action.At present, commonly used 304 rustless steels of all types of electrodes are made, and have relatively
Good antioxidation and corrosion resistance, but in operation process, tissue is being cut by the tissue heat effect that high frequency electric knife produces
While hemostasis, also result in the surface adhesion being organized in electrode.Tissue stick to electrode surface be not only difficult to remove but also
Can increase the resistance of whole current loop, cause the electric current density of electrode surface to reduce, appearance cannot be cut insufficient with blood coagulation
Phenomenon.
At present, the braking measure adhered to for electrode surface tissue focuses primarily upon sets up auxiliary device and to electrode surface
It is modified two aspects.In terms of setting up auxiliary device, major measure is to set up saline infusions device and cold at electrode
But circulating device, they reach to alleviate electrode surface by the buffer action of normal saline and control electrode surface temperature respectively
The effect that tissue adheres to；Then mainly by preparing hydrophobic coating (such as politef) reduction electrode in terms of electrode surface reforming
Surface energy, alleviates electrode surface tissue and adheres to.But, saline infusions and the cooling auxiliary device such as circulation then need to be in electrodes
Portion arranges lacuna, not only can increase the original geomery of electrode, and can increase processing and manufacturing difficulty and cost.And polytetrafluoroethyl-ne
The high-temperature stability of the polymer coatings such as alkene endures query to the fullest extent the most always, has research to occur during once pointing out electrotomy
High temperature can cause politef to decomposite noxious substance and water reacting generation Fluohydric acid. human body produces injury human body, there is peace
Full hidden danger.
Summary of the invention
It is an object of the invention to provide the electric knife electrode of a kind of anti-adhesive, this kind of electric knife electrode has preferable anti-adhesive energy
Power, and its handling ease, preparation cost are low, use safety.
The present invention realizes the first technical scheme that its goal of the invention used: the electric knife electrode of a kind of anti-adhesive, bag
Include the spacing plastic sheath in the work portion and connecting portion that the connecting portion that electrode handle with electric knife connects contacts with tissue, its
It is characterised by: the work portion of described electrode is made up of tungsten or tungsten alloy.
Further, the connecting portion of the electrode of the present invention is also made up of tungsten or tungsten alloy.
The present invention realizes the second technical scheme that its goal of the invention used: the electric knife electrode of a kind of anti-adhesive, bag
Include the spacing plastic sheath in the work portion and connecting portion that the connecting portion that electrode handle with electric knife connects contacts with tissue, its
It is characterised by: the Surface Machining in the work portion of described electrode has tungsten or tungsten alloy coating.
Further, the connecting portion of the electrode of the present invention is machined with tungsten or tungsten alloy coating.
Compared with prior art, the invention has the beneficial effects as follows:
One, applicant studies discovery: the electrode that existing employing 304 rustless steel is made, in the mistake of high frequency electric knife cutting tissue
Cheng Zhong, the arc discharge that region is little and energy is concentrated that electrode surface occurs, can cause electrode surface local that thousands of degree occurs
TRANSIENT HIGH TEMPERATURE, induction fusing point is about the stainless steel electrode surface of 1500 DEG C and occurs micro-melted, causes electrode surface roughness
Spread with matrix element, and then the tissue of aggravation electrode surface adheres to.
And the electrode of the present invention uses tungsten or tungsten alloy to make (the first scheme) in work portion, or in work portion
Surface Machining have tungsten or tungsten alloy coating (first scheme), owing to the fusing point of tungsten or tungsten alloy is 3300 DEG C of left sides
The right side, during high frequency electric knife cutting tissue, can avoid electrode surface to occur micro-melted, and electrode surface will not occur slightly
Roughening and matrix element diffusion, and then alleviate the bond strength of the adhesion organization of electrode surface, reduce the difficulty of electrode cleaning,
Save operating time so that the electrode of the present invention has preferable anti-adhesion ability.
Test shows that the bond strength of the adhesion organization of the present invention is only 1.65Mpa, gluing of relatively 304 stainless steel electrode surfaces
The bond strength (4.11Mpa) of attached tissue, reduces by more than 50.
Two, electrode work portion or the electrode of the present invention all by tungsten or tungsten alloy injection mo(u)lding or can be spattered by surface
Penetrating formation, than processing interior cavity reperfusion structure on small electrode, handling ease of the present invention, preparation cost are low.
Three, than human body being produced the polytetrafluorethylecoatings coatings poisoned, the entirety in the electrode work portion of the present invention or
Face coat is that tungsten or tungsten alloy, tungsten or tungsten alloy have preferable biocompatibility, and it uses safety.
The present invention is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.
