Description
Affiliated technical field
The present invention relates to a kind of medical operation electrode and manufacture method, especially can in operation, carry out anatomic tissue, 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 the 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 the medical speciality.Therefore electric field has more advantage in safety not by human body during bipolar electrode work.
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 owing to its distinctive safety and efficiently, begin more to be paid attention to.Because actual medical is used comparatively complicated and various, 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.
Bipolar electrode cuts in saline and the solidifying effect of heat in order to improve, and the contact form and the electrode form that need design to be more suitable for are to satisfy the needs of the needs of daily operative treatment, especially open surgery and Microendoscopic complicated operation.
Perfusion and drainage channel are set outside the electrode knife bar not only take up space, the restriction range of operation, and hinder the patient visual field.Therefore need to provide perfusion and drainage system for electrode.
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, normal saline can be 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, procedures electrode possesses simultaneously anatomic tissue, drying, melts, blood coagulation, perfusion saline be or/and multiple functions such as suction pumps, and 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:
At electrode knife head one or more contact isolated insulation posts are set, one or more metal contact are set on each insulated column; On the point of a knife of electrode, be provided with at least one and excite contact by what wire guide was made; The insulation of electrode knife bar appearance is provided with a metal tube at least in the electrode knife bar, metal tube exposes the appearance insulation in the cutter head working end exposed part serves as a backflow contact; The filling system that water injection pipe and electrode tip water filling port form in electrode arranges by water injection conduit, electrode; Or drainage system by electrode tip attracts mouthful, electrode inner drainage tube and drainage catheter form is set; Or above-mentioned perfusion and drainage system be set simultaneously.
