Description
Technical field
This utility model relates to a kind of Plasma surgical electrode, belongs 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, be applied to the every field of ENT & HN Surgery Dept. gradually, the ultimate principle of this technology is the electric field utilizing certain frequency, convert the electrolyte between Plasma surgical electrode and target tissue to 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 by energy delivery to target tissue, dissociate and form the molecular link of cell component in target tissue, cell in target tissue is disintegrated in units of molecule, be decomposed into carbohydrate and oxide, and cause the coagulation necrosis of tissue, thus reach and 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 very short, and the time of about 15-20 minute, namely postsurgery symptoms is eased, generally postoperatively can not to recur again, be applicable to the type of repairing of the various tissue of human body, excision and blood coagulation, the safe no pain of operation process, can effectively treatment of allergic rhinitis, chronic rhinitis, snoring, pharyngitis etc.
Plasma surgical electrode is for completing low-temperature plasma operation and the operating theater instruments that design, usually needs possess excision, solidify, rinse, the function such as suction.Wherein whether water structure is reasonable, is the key issue affecting solution conveying effect and developing result, but the special research for Plasma surgical electrode feed liquid way and report are also seldom.
Summary of the invention
The purpose of this utility model is 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 scheme that this utility model adopts is as follows: feed liquid way Plasma surgical electrode inside a kind of hollow edged electrode, comprise sheath, outer tubular electrode, interior electrode base, interior electrode, draining hole and water filling port, sheath is insulant, be adjacent to and be coated on outer tubular electrode, sheath is exposed in the end of outer tubular electrode, there are wire and hydrophobic channel in outer tubular electrode inside, electrode base in the installing insulating of outer tubular electrode end, interior electrode and external electrode are also isolated by electrode in interior electrode base is fixing, draining hole is in the middle of interior electrode base, draining hole is communicated 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 is communicated with liquid feeding channel.
Described outer tubular electrode is the good rustless steel tubular structure of electric conductivity.
Described interior electrode base installation by adhering is in outer tubular electrode end.
Described interior electrode base adopts high-temperature resistance plastice PTFE, PEEK, PI or base of ceramic.
Described interior electrode adopts the materials such as molybdenum, gold, tungsten or platinum to make thread or lamellar.
The sheath that described sheath adopts PVC, PE or PTFE material to make.
Usefulness of the present utility model is: the liquid feeding channel that this utility model provides is arranged on hollow edged electrode inside, without the need to the liquid feeding channel outside electrode, therefore Plasma surgical electrode has less radial dimension, more conveniently to perform the operation in conjunction with endoscope, improve the visual field of operative doctor, and reduce the wound of operation; Meanwhile, the mode of feed flow inside hollow edged electrode and between interior electrode base, liquid stream can direct cooling electrode, can improve the electric discharge quality of procedures electrode on the one hand, can improve the life-span of procedures electrode on the other hand; In addition, the plasma discharge of procedures electrode must could produce in the solution smoothly, the outlet of its liquid feeding channel is arranged in hollow edged electrode surveys between interior electrode base, clog-free directly the entering of solution can be made to treat operative region, to ensure that operative region solution is sufficient, ensure the even generation of operative region plasma discharge, and therefore improve surgical quality.
