On the basis of the prior kindred electrode, the front end of the radio-frequency ablation electrode is additionally provided with the ultrasonic probe, so as to be convenient for scanning and detecting the target tissue in the previous period of performing the radiofrequency ablation and synchronously performing the radio-frequency ablation. The front end of the electrode is also provided with a temperature sensor, marked scale is marked at the outer side of the sleeve of the electrode, and an electrode tip can have puncture performance or can not have puncture performance. The utility model has simple structure, convenient operation and high accuracy, can effectively position the target tissue, shortens the operation time, and improves the operation efficiency.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of electrode assembly that is used for the radio-frequency (RF) ablation of the soft tissue of treatment human body (comprising tumor) that Wicresoft hinders.
Technical background
The ablating electrode implementation procedure normally relies on B ultrasonic or down straight in the CT guiding, the tumor portion of directly thrusting the patient again.R-f generator passes through ablating electrode, cooperate ground electrode and body tissue to constitute current loop, conductive ion in the body tissue and polar molecule change its direction of motion fast under the effect of radio frequency alternating current, but because volume difference, the quality difference of various conductive ions and the quantity of electric charge difference that is had, cause the counter-rotating between them and the difference of movement velocity, thereby generation frictional heat, and because the high current density that exists around the ablating electrode will form a localized hyperthermia district around the electrode.Learn that from pathology is clinical when temperature reached more than 60 ℃, the protein in the tissue can change its characteristic because of heating, the irreversibility necrosis that causes tumor cell to become.And outside the coagulation necrosis district in 43 ℃-60 ℃ the thermotherapy district, tumor cell is killed, and normal cell still has the ability that autotherapy recovers.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, easy to operate, effectively localizing objects tissue, shorten operating time, improve operation efficient to organizing interior tumor to carry out scanning probe and carrying out the electrode assembly of radiofrequency ablation therapy.
This utility model is designed for the electrode of radiofrequency ablation therapy, be at existing a kind of improvement of similar electrode assembly, its improvements are at primary electrode device front end except having temperature sensing device, also be added with ultrasonic probe, and the structure of other parts is with the electrode of radio-frequency (RF) ablation is similar usually at present, comprise sleeve pipe, handle etc., and have and backstage radio-frequency (RF) ablation instrument and compatible interface plug of ultrasonic machine while.
This radio-frequency ablation electrode device has ultrasonic probe, in order to scanning in earlier stage in radio-frequency (RF) ablation and detection of a target tissue, and the synchronization implementation radio-frequency (RF) ablation.
It is simple in structure, easy to operate that this utility model designs, the accuracy height, and effectively the localizing objects tissue carries out radiofrequency ablation therapy in the very first time to destination organization, shortens operating time, improves therapeutic effect.
