Abstract
The utility model relates to a double pole radio frequency knife, which solves the technical problems that skin can be easily scalded, operation is not convenient, therapeutic effect is bad, etc. in the prior art. An electrode plate B is arranged in an electrode cavity, a water filling port B is also arranged on a die frame and is communicated with an inner guide pipe which is communicated with the electrode plate B in the electrode cavity. An inner insulating coating layer is arranged on the outside of the inner guide pipe, and the end of an outer guide pipe is provided with a water outlet hole. The ends of the outer guide pipe are connected with the ends of the inner guide pipe through insulating pipes among electrodes, triangular needle heads are fixed on the insulating pipes among the electrodes and conducting sheets are arranged among the ends of the inner guide pipe and the triangular needle heads. The utility model can lead high frequency current strength to be concentrated in a target area, which leads the heat efficiency of an electrical field to reach highest. Consequently, tumor can be totally covered and eliminated. The utility model adds tumor ablation range, eradicates the danger that a patient's skin is scalded, and avoids unstable factors of therapeutic effect because of the size of impedance of the patient's physique.
Description
Technical field
This utility model relates to medical apparatus and instruments, specifically a kind ofly is used for the bipolar radio frequency knife that human tumor Wicresoft melts.
Background technology
Radio-frequency technique is applied to the history of clinical existing decades, studies show that the above high frequency electric of 100KHz to human body be perfectly safe and nerve stimulation can not appear, it generally is painless utilizing high frequency electric to treat.The flexible cutter of existing single-stage radio frequency comprises a mould bases, and with also be fixed with a conduit that is connected with hollow edged electrode and water filling port in mould bases forms water filling port of one and hollow edged electrode, mould bases, catheter outer surface scribbles the Teflon insulating barrier, the end of conduit is fixed with a rhizoma sparganic syringe needle, has apopore on the syringe needle.Will utilize high frequency electric that but the syringe needle percutaneous puncture of water filling is gone in the tumor down image-guided during use, constitute a complete loop with the neutral pole plate that is bonded on the human body, form high-intensity electron ion concussion in inside tumor, thereby make tumor cell at high temperature dead.Because this kind monopolar radio frequency cutter will paste a neutral pole plate in use on skin, and neutral pole plate wants the long time catch cropping to have in human body, can produce bigger heat simultaneously, so be easy to scalded skin.In addition, existing single-stage radio frequency knife is subjected to the influence of its structure to produce the regional limited of electrode, when treating bigger tumor, to use simultaneously with two monopolar radio frequency cuttves, therefore need on human body, to puncture twice, and two monopolar radio frequency cuttves must be parallel when using, otherwise the thermal field that produces is inhomogeneous, does not reach the effect of treatment; In addition, two monopolar radio frequency cuttves can't use simultaneously in some narrow positions of human body.
Summary of the invention
The purpose of this utility model is in order to solve the easy scalded skin of neutral pole plate that prior art exists, and technical problems such as two monopolar radio frequency cuttves are very inconvenient when using simultaneously, therapeutic effect difference, and a kind of bipolar radio frequency knife that can thoroughly eradicate skin scald danger, increase the tumour ablation scope that provides.
In order to solve the problems of the technologies described above, this utility model comprises the water filling port A with the mould bases one, electrode cavity, be fixed on the mould bases and water filling port A, the outer catheter that battery lead plate A is connected in the electrode cavity, and rhizoma sparganic syringe needle, it is characterized in that: also be provided with battery lead plate B in the described electrode cavity, also be provided with water filling port B on the mould bases, this water filling port B is connected with an inner catheter, and the battery lead plate B in inner catheter and the electrode cavity is connected, and inner catheter is provided with interior insulating coating outward, the outer catheter end is provided with apopore, outer catheter, the end of inner catheter is connected by the electrode insulation pipe, and the rhizoma sparganic syringe needle is fixed on the electrode insulation pipe, is provided with conducting strip between inner catheter end and rhizoma sparganic syringe needle.
In the further detailed structure of this utility model, also have following technical characterictic: described rhizoma sparganic syringe needle is fixed by connection tube and electrode insulation pipe, connects on the tube wall to have the syringe needle apopore.
In the further detailed structure of this utility model, also have following technical characterictic: described inner catheter is sleeved in the outer catheter.
In the further detailed structure of this utility model, also have following technical characterictic: described inner catheter and outer catheter are arranged side by side in mould bases.
In the further detailed structure of this utility model, also has following technical characterictic: be provided with reservoir between described inner catheter and the rhizoma sparganic syringe needle.
Following advantage of this utility model tool and good effect: because this utility model has adopted above-mentioned bipolar power supply water-supply structure, can only concentrate on the current intensity of high frequency in the target area, make the thermal efficiency of electric field reach the highest, thereby tumor all can be covered deactivation, increased the scope of tumour ablation greatly, and the danger of having eradicated the sufferer skin scald, stopped the size therapeutic effect factors of instability of sufferer because of the body constitution impedance.
