Abstract
The invention relates to a dipolar radio frequency for solving the problem of easy scalding skin, inconvenient usage and worse effect of treatment in present technology. Wherein, an electrode plate (B) is mounted inside the electrode chamber; the die carrier has a affusion hole (B) connected to a inner tube which is through with the electrode plate (b); a inner insulating coating is arranged outside the inner tube; a water outlet is arranged on the end of outer tube; the ends of outer and inner tubes are connected to each other via the inter-electrode insulating tube; a tri-ensiform needle is mounted on the inter-electrode insulating tube; and a conductive slice is arranged between the end of inner tube and the tri-ensiform needle. Said invention can centralize the current intensity in high frequency only in the target area, to make the thermal efficiency of electric field reach highest, so the tumour can be all covered and inactivated while the ablation range of tumour can be increased, the dangerous of scalding the skin of patient is deracinated and the problem that the unstable treating effect coursed by the amount of the impedance of patient body can be avoided.
Description
Technical field
The present invention relates to medical apparatus and instruments, specifically a kind ofly be 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 objective of the invention 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, the present invention includes 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 the present invention, 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 the present invention, also have following technical characterictic: described inner catheter is sleeved in the outer catheter.
In the further detailed structure of the present invention, 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 the present invention, also has following technical characterictic: be provided with reservoir between described inner catheter and the rhizoma sparganic syringe needle.
Following advantage of tool of the present invention and good effect: because the present invention 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.
