Description
Technical field
This utility model relates to RF medical technical field, especially a kind of acupuncture needle-like radio frequency electrical pin.
Background technology
Radio-frequency (RF) ablation (RFA) is a kind of Minimally Interventional Therapy method, and nineteen ninety Rossi and Mcgahan etc. report that RFA is applied to melting of animal livers tissue at first, subsequently by the liver neoplasm of this technology treatment mankind.At present, RFA technology has been widely used in the disease for the treatment of the multiple organ of whole body, except can deactivation tumor, tumor load can also be reduced reach pain relieving, reduce the objects such as hormone secretion, also have research to be applied to non-tumor disease as treatment hypersplenism (spleen is high), benign thyroid nodules, supraventricular tachycardia, atrial fibrillation etc. in addition.RFA is a kind of thermotherapy method, its ultimate principle utilizes heat energy to damage pathological tissues, sending rf wave by electrode makes the ion in its surrounding tissue and the vibration of polarity macromole clash into frictional heating, pathological tissues is heated to effectively treat temperature range and maintains certain hour and can make tissue generation coagulation necrosis, to reach living tissue object of locally going out.Meanwhile, radio frequency thermal effect should be able to make the blood vessel of surrounding tissue solidify, and forms a reaction zone, makes it to prevent neoplasm metastasis to tumor feeding.
The heat effect that radio-frequency (RF) ablation produces is also different according to the different conduction of tissue., irreversible necrocytosis can be there is in solidifying due to albumen during temperature >60 DEG C.Tissue charring during temperature >100 DEG C, evaporation, reduces electricity and conduction of heat.Target organ temperature 60-100 DEG C, time 5-10min time single-needle electrodes tumour ablation necrotic tissue diameter be 15mm.The monopolar electrode of general use is used for the pathological changes of diameter <3cm, and the radio-frequency (RF) ablation time is 5-10min, and central temperature is 100 DEG C or until temperature cannot be delivered to target tissue.Strengthen power stage can not increase and melt ablation range.
In order to increase ablation range, utility model umbrella electrode increases eletrode tip area and interior cold electrode (wind circulation and water cycle electrode) again.Umbrella electrode holds many umbrella frames, there is the microtubule of hygrosensor and supply cold wind or normal saline turnover to lower the method for tip temperature in interior cold electrode, avoid the carbonization of needle point surrounding tissue, improve tissue conductive, neoplasm necrosis district can be made larger, and necrosis area can reach 50mm.But the electrode needle usually needed is thicker, wound increase, complication and the corresponding increase of bleeding risk.
The needle body diameter general range 1.0-1.9mm of tradition ablation needle/radio frequency needle, to ensure that certain intensity is convenient to thrust Deep Lesions position, the insulant of needle body insulating segment mostly is sleeve pipe, heat-shrink tube.Size all on 0.025mm, the needle body diameter 0.1mm-0.5mm of acupuncture needle-like radio frequency electrical pin.Insulating barrier is coating material, wall thickness 0.010mm-0.050mm, and withstand voltage is within more than 2000V 3500V.
Utilize the characteristic of the fine size of acupuncture needle, the feature that insulating coating is thin reduces the diameter of whole pin.Have that damage is less, painful light, complication and bleeding risk corresponding lower, the plurality of advantages such as repeatedly can to carry out.Especially meticulous pathological changes and the corresponding larger patient of bleeding risk is applicable to.
For the control of ablation range, the ablation range of traditional ablation needle/radio frequency needle controls at 2.5cm-4.5cm.The ablation range control accuracy high scope 2mm-6mm of acupuncture needle-like radio frequency electrical pin single needle.Utilize the feature of acupuncture needle in conjunction with its size and needle body toughness, design a kind of target zone high-precision acupuncture needle-like radio frequency electrical pin.
