Description
Affiliated technical field
The present invention relates to a kind of medical operation electrode, especially can carry out anatomic tissue in operation, or tissue is dry, or ablation of tissue, or the bipolar electrode of low temperature blood coagulation.
Background technology
At present, in known procedures electrode, excite contact and the backflow contact of a class electrode are separated from each other, needle-like excite the contact focus, the backflow contact of lamellar (electrode slice) is attached to patient, is referred to as monopolar electrode on medical speciality.Another kind of electrode is to provide simultaneously in work end to excite contact and current reflux contact, is referred to as bipolar electrode on medical speciality.During bipolar electrode work, electric field not by human body, therefore has more advantage in safety.
In the bipolar electrode field, be used for tweezer shape electrode---the bipolar tweezer of blood coagulation, there has been the use of last 100 years historical.Another kind of will excite contact and backflow contact to be arranged on the cutter head of a knife bar, and anatomic tissue, drying will be provided simultaneously, melt the bipolar electrode with blood coagulation, and due to its distinctive safety and efficiently, begin more to be paid attention to.Use comparatively complicatedly and various due to actual medical, in different field of surgery, the version requirement of electrode is not quite similar, thereby the electrode form that more corresponds to actual needs need to be arranged.
Make electrode contact with seal wire and can obtain satisfied Electric Field Distribution effect, but because bipolar electrode cutter head space surface is limited, make the seal wire contact difficulty of processing precise larger.Make accurate complicated electrode contact by the metal incision technology, can improve manufacturing effect, represented following direction of bipolar electrode contact manufacturing.
Bipolar electrode cut in saline and the solidifying effect of heat in order to improve, and makes for improving being easy to get property simultaneously, need design contact form and the electrode form that is more suitable for, and to satisfy the needs of daily operative treatment, the needs of open surgery and Microendoscopic complicated operation especially.
Summary of the invention
In order to adapt to medical operating to the actual requirement of ambipolar procedures electrode, be convenient to simultaneously processing, the invention provides a kind of medical bipolar electrode, utilize metal to scribe technology, manufacture and design various forms of electrode contacts.If necessary, perfusion and drainage system can be installed easily thereon, normal saline is directed to therapentic part from bag of saline (bottle), or abandon the liquid bottle from therapentic part with what tissue debris and saline were directed to vacuum extractor, thereby make that procedures electrode possesses simultaneously anatomic tissue, drying, melts, blood coagulation, perfusion saline be or/and multiple functions such as suction pumps, the complicated operation that especially is fit to open and Microendoscopic operates.
The technical solution adopted for the present invention to solve the technical problems is:
One or more contact isolated insulation posts are set on electrode knife head, one or more metal contact are set on each insulated column; At least arrange one on the point of a knife of electrode and excite contact by Metal Flake (thickness is less than the solid of its length and width) or with what foil was scribed; The insulation of electrode knife bar appearance wherein arranges a metal tube at least, and metal tube exposes the part of appearance insulation and serves as a backflow contact in the working end; Cutter head contact isolated insulation post is arranged at the front end of metal tube in electrode stem, and the insulant of insulated column is resin, plastics, silicone rubber or pottery, or the combination of above several insulant.The metal tube front end face is parallel with the front surface of insulated column on it is set, and the suitable creep age distance of being separated by.
With saline swollen chamber the time, electrode does not need the perfusion of saline system, but as required drainage system can be set on electrode; The occasion that there is no saline at therapentic part can arrange the filling system that is comprised of water injection pipe in water injection conduit, electrode and electrode tip water filling port on electrode; Or above-mentioned perfusion and drainage system be set simultaneously.The water injection conduit of electrode is connected with drainage catheter with infusion apparatus joint and is connected with attractive device connector; The outer cone joint of the specification of infusion apparatus joint and medical Transfusion device is supporting, the specification of attractive device connector and the connecting pipe matched of Medical vacuum extractor.When the needs water filling, bag of saline (bottle) is connected with the infusion connector of electrode by medical Transfusion device, saline under action of gravitation, the electrode infusion apparatus joint of flowing through, water injection conduit enters electrode knife bar water-injecting cavity, flows out from the cutter head water filling port; At needs during with the electrode drain, saline, tissue debris and the smog at cutter head position attract mouthful via cutter head under the effect of negative pressure, the electrode inner drainage tube, and drainage catheter and attractive device connector are abandoned the liquid bottle to vacuum extractor.
Cutter head attracts mouth can be arranged on the front surface of contact isolated insulation post.The position can be arranged on centre of surface, or amesiality setting.It can be circular or semicircle attracting mouth.
Adapt to dissimilar operation, the point of a knife contact can be to comprise one or more list structure contacts of being made by sheet metal.If the mouth of attraction is arranged, the segment conductor of contact covers and attracts mouth.Except vertical bar shape contact, the insulated column surface can also arrange the contact of circular arc strip.Each conductor can divide and is arranged, and more common form is mutually to intersect or arranged in a crossed manner.
Adapt to dissimilar operation, the point of a knife contact can be to comprise the circle made by sheet metal (in inclined-plane point of a knife situation for oval), fan-shaped, fillet polygon or loop configuration lamellar contact.Have simultaneously one or several circular holes, elliptical aperture, semicircle orifice or delthyrium (circular arc delthyrium or fillet delthyrium) thereon.If the mouth of attraction is arranged, the segment conductor of contact covers and attracts mouth.
Adapt to dissimilar operation, can have one or several semicircles, rectangle or vee on the outer edge of above-mentioned point of a knife contact, thereby adjust the Electric Field Distribution of point of a knife.
Adapt to dissimilar operation, the contact of being made by sheet metal on point of a knife can be in a plane, also can be in the middle of same contact plane.When contact is in same plane, Yi Bian the contact plane can also separate with the front surface of insulated column, form one less than the angle δ of 90 ° between contact plane and insulated column front surface.As required, also can be arranged in parallel between the front surface of contact plane and contact isolated insulation post, comprise and to lie prostrate on the insulated column front surface by note, at this moment be equivalent to angle δ and equal 0 °.
Adapt to different type of surgery, the front surface of welding tip contact isolated insulation post can with the sagittal plane shape of welding tip α in an angle, also can be axially vertical with welding tip, at this moment be equivalent to angle α and equal 0 °.
Adapt to different operations, electrode can be the straight-bar form, also can a bent angle β be set according to the operation needs between welding tip and electrode knife bar.Be to adapt to the requirement of endoscopic surgery, the electrode knife bar is arranging a bent angle θ reverse with the point of a knife direction near the handle place.In deep operation, the electrode knife bar can also arrange near working end place one with point of a knife direction bent angle λ in the same way.
The invention has the beneficial effects as follows, make the bipolar surgery electrode be more suitable for different operating actual needs.Improve simultaneously the manufacturability of the electrode contact of different operations.
