Abstract
The invention relates to a plasma surgical electrode, in particular to a plasma surgical electrode with fluid being supplied on the inner side of a tubular electrode. A jacket coats a tubular outer electrode in a sticking manner; an insulating inner electrode base is arranged on the end part of the tubular outer electrode; the inner electrode base is used for fixing an inner electrode and isolating the inner electrode from the outer electrode; a drainage port is formed in the middle of the inner electrode base, and is communicated with a dewatering channel; a fluid supply channel is formed between the outer wall surface of the dewatering channel and the inner wall surface of the tubular outer electrode; a water injection port is formed between the inner side of the tubular outer electrode and the inner electrode base, and is communicated with the fluid supply channel. The water injection port is a channel between the inner side of the tubular outer electrode and the inner electrode base, and working fluid is directly delivered to a discharge region and a surgical region, so that the radial size of the surgical electrode is reduced, and surgical wounds are reduced; through the fluid supply way, cooling of the electrode is facilitated, and the visual field of a surgeon is improved; meanwhile, a solution is induced to directly enter the surgical discharge region, so that sufficient discharge mediums are ensured, and the surgical quality is enhanced.
Description
Technical field
The present invention relates to a kind of Plasma surgical electrode, belong to medical plasma body field of surgical.
Background technology
Low temperature plasma ablation techniques is because having safety, Wicresoft, simple to operate, the advantages such as patient suffering is little, the most gradually it is applied to the every field of ENT & HN Surgery Dept., the ultimate principle of this technology is to utilize the electric field of certain frequency, electrolyte between Plasma surgical electrode and target tissue is converted into low-temperature plasma figure, the plasma thin layer of a high aggregation is formed in procedures electrode front end, powerful electric field makes free strip charged particle in plasma thin layer obtain enough energy, and transfer energy to target tissue, dissociate and target tissue constitutes the molecular link of cell component, the cell in target tissue is made to disintegrate in units of molecule, it is decomposed into carbohydrate and oxide, and cause the coagulation necrosis of tissue, thus reach to melt and cutting effect.Low temperature plasma ablation belongs to Minimally Invasive Surgery, the safety of local mucosa tissues structure can be kept, and can effectively alleviate postoperative edema and pain, time of melting is the shortest, the time of about 15-20 minute, and postsurgery symptoms is i.e. eased, the most postoperative will not recur again, it is applicable to type of repairing, excision and the blood coagulation of the various tissue of human body, the safe no pain of operation process, can effectively treat allergic rhinitis, chronic rhinitis, snoring, pharyngitis etc..
Plasma surgical electrode is for completing low-temperature plasma operation and the operating theater instruments that designs, it usually needs possess excision, solidify, rinse, the function such as suction.Wherein water structure is the most reasonable, is to affect solution conveying effect and the key issue of developing result, but is specifically designed for the research of Plasma surgical electrode feed liquid way with report seldom.
Summary of the invention
It is an object of the invention to overcome above-mentioned not enough problem, the Plasma surgical electrode of feed liquid way inside a kind of hollow edged electrode is provided, between interior electrode base and hollow edged electrode, liquid feeding channel is set, be conducive to reducing Plasma surgical electrode radial dimension, cooling electrode, improves the visual field of operative doctor, and inducing solution enters operation region of discharge smoothly simultaneously, ensure that in operation, region of discharge solution is sufficient, improves surgical quality.
The technical solution adopted in the present invention is as follows: feed liquid way Plasma surgical electrode inside a kind of hollow edged electrode, including sheath, outer tubular electrode, interior electrode base, interior electrode, draining hole and water filling port, sheath is insulant, it is adjacent to be coated on outer tubular electrode, sheath is exposed in the end of outer tubular electrode, wire and hydrophobic channel is had inside outer tubular electrode, electrode base in insulation is installed in outer tubular electrode end, interior electrode is also isolated by the fixing interior electrode of interior electrode base with external electrode, draining hole is in the middle of interior electrode base, draining hole connects with hydrophobic channel, liquid feeding channel is formed between hydrophobic channel outside wall surface and outer tubular electrode internal face, water filling port is arranged on inside outer tubular electrode and between interior electrode base, water filling port connects with liquid feeding channel.
Described outer tubular electrode is the rustless steel tubular structure that electric conductivity is good.
