Abstract
The invention relates to a plasma operation electrode, in particular to a rotary liquid feeding type plasma operation electrode. A protective jacket is made of an insulating material and is wrapped on a tubular external electrode, and the end of the tubular external electrode is exposed out of the protective jacket; an insulating internal electrode base is mounted at the end of the tubular external electrode; the internal electrode base is used for fixedly mounting an internal electrode and isolating the internal electrode from the external electrode; a drainage opening is formed in the internal electrode base and is communicated with a drainage pipe inside the external electrode; a spiral liquid feeding tank is arranged between the protective jacket and the tubular external electrode. The flow direction and flow field of liquid can be controlled by changing a spiral angle, the liquid flows along a spiral line due to an inertia effect after spraying out from a water injection port, and solution can be induced to enter an operation discharging area in a rotating mode, so that uniform and sufficient solution in the discharging area in the operation process is guaranteed, and the operation quality is improved. Meanwhile, without changing the structures of the tubular external electrode and the internal electrode, the processing difficulty and manufacturing cost of the plasma operation electrode can be reduced.
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, 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.
And 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, it is the key issue affecting solution conveying effect and developing result, current product generally to adopt between sheath and outer tubular electrode cavity as liquid feeding channel, also have and adopt cavity between outer tubular electrode and inner pipette as liquid feeding channel, but these two kinds of forms, liquid feeding channel all do not have special consideration, the special research for Plasma surgical electrode feed liquid way and report are seldom, and in practical application, operation liquid flows by gravitational force into liquid feeding channel, flow out via liquid feeding channel water filling port, it is uneven to there is feed flow when being arranged on clinical practice in these two kinds of liquid feeding channels, the slack problem of fluid, therefore the stablizing effect of impact operation and efficiency.
Summary of the invention
The object of the invention is to overcome above-mentioned not enough problem, provide a kind of Plasma surgical electrode of rotary liquid feeding mode, inducing solution enters operation region of discharge in a rotative pattern, ensures region of discharge dissolution homogeneity, abundance in operation process, improves surgical quality.
The technical solution adopted in the present invention is as follows: a kind of Plasma surgical electrode of rotary liquid feeding mode, comprise sheath, outer tubular electrode, interior electrode base, interior electrode, draining hole and water filling port, sheath is insulant, to be coated on outer tubular electrode and sheath is exposed in the end of outer tubular electrode, in insulation, electrode base is arranged on outer tubular electrode end, interior electrode and external electrode are also isolated by electrode in interior electrode base fixed installation, draining hole is on interior electrode base and be communicated with the drainage tube of external electrode inside, spiral helicine feed tank is provided with between sheath and outer tubular electrode.
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.
Described spiral helicine feed tank, inner surface can be adopted to be coated on outer tubular electrode with the sheath of spiral grooves formed, also can process spiral grooves at outer tubular electrode outer surface to coordinate with sheath and form spiral feed tank, or coordinate with sheath be wound around filament on outer tubular electrode after and form spiral feed tank.
The sheath that described sheath adopts PVC, PE or PTFE material to make.
Usefulness of the present invention is: existing Plasma surgical electrode does not have special consideration on liquid feeding channel, jet direction directivity is strong, and flow Field Design is random, is presented as that the supply of region of discharge solution is not smooth during actual use, spray dispersion, carrying out smoothly of impact operation.Different from existing low temperature plasma procedures electrode, liquid feeding channel and the water filling port of procedures electrode of the present invention are spiral type, can control flow direction and flow field by changing spiral angle.The liquid entering liquid feeding channel is greater than linear path due to spirality channel resistance, liquid can not produce cutout phenomenon in passage, feed flow is continuous, sufficient, because effect of inertia flows along helix after liquid sprays from water filling port, operation region of discharge can be entered in a rotative pattern by inducing solution, ensure region of discharge dissolution homogeneity, abundance in operation process, and solution jet is concentrated, and can improve surgical quality.Meanwhile, the present invention is without the need to changing the structure of outer tubular electrode and interior electrode, and its difficulty of processing and manufacturing cost are not high.
