Description
Technical field
The present invention relates to a kind of disposable radio-frequency (RF) ablation apparatus, particularly relate to a kind of for tumor with the radio frequency of pathological tissues
The electrode needle system of the temperature controlled radio frequency adjustable water filling ablating electrode pin of ablation.
Background technology
Along with science and technology and the progress of oncology now, radio-frequency ablation procedure increasingly becomes a kind of effective side for the treatment of cancer
Formula.Radio-frequency ablation procedure typically uses local anesthesia, scans through CT or B ultrasonic and positions aura, electrode needle is thrust focus
Behind center, by the monitoring impedance of lesion tissue, the isoparametric change of temperature, it is automatically adjusted the output of radio-frequency (RF) ablation, opens
Begin to carry out radio-frequency (RF) ablation, make lesion tissue quickly produce the process of large-scale coagulation necrosis.Radio-frequency ablation procedure has 2 kinds at present
Mode, one melts for internally cooled, i.e. leads to cooling circulating water in operation process inside shank so that shank temperature keeps one
Under lower temperature (usually 25-35 DEG C), prevent the adhesion of shank tip；Another kind melts for water injection type, i.e. melts
Operation, by peristaltic pump toward aura tissue injection 0.05-0.5ml/min normal saline, normal saline penetrates in tissue,
Change the impedance of aura tissue so that radio-frequency (RF) ablation scope is bigger.
From structure, the most traditional adjustable water injection type ablation needle regulation visual field is unintelligible, and adjustable feel is poor, handle
Relatively slightly heavier, at CT and B ultrasonic in aura position fixing process, need to increase by a holder and be fixed ablation needle to ensure to disappear
Melt pin to be perpendicular to aura position aura tissue is melted；The most traditional adjustable water injection type ablation needle water injection pipe is relatively thin,
Tube wall is relatively thin, and water pipe separates with radio frequency line, and the pulling force that can bear is less, occurs water pipe phenomenon of rupture more.From performance, pass
Needle point heating region was both cooled due to needle tip position by the adjustable water injection type ablation needle of system without no-cooling-water, again without
Effectively prevent because high temperature exothermic causes tissue adhesion's treatment measures, cause needle point adhesion phenomenon in operation process serious, lead
Cause operation unexpected.
Summary of the invention
Present invention aims to the deficiency of existing adjustable water injection type ablation needle, it is provided that a kind of adjustable water filling is melted
The electrode needle system of electrode needle, water pipe is not susceptible to phenomenon of rupture, can improve or solve because high temperature exothermic is led again in performance
Cause the adjustable water filling ablating electrode pin of tissue adhesion.
