Description

Medical electric needle

Technical Field

The utility model belongs to the technical field of medical use, and particularly relates to a medical electric needle.

Background

Radiofrequency ablation (RFA) is a minimally invasive interventional procedure, and application of RFA to ablation of animal liver tissue was first reported in 1990 by Rossi and Mc gahan, and subsequently this technique was used to treat human liver tumors. At present, the RFA technology is widely applied to treating diseases of various organs of the whole body, not only can inactivate tumors, but also can reduce tumor burden to achieve the purposes of relieving pain, reducing hormone secretion and the like, and further, the RFA technology is also researched to be applied to non-tumor diseases such as treatment of spleen hyperfunction (spleen hyperfunction), benign thyroid nodule, supraventricular tachycardia, atrial fibrillation and the like. RFA is a thermal therapy method, and its basic principle is that heat energy is used to destroy pathological tissue, and the electrode emits radio frequency wave to make ions and polar macromolecules in the surrounding tissue vibrate, rub and heat, so that the pathological tissue is heated to effective therapeutic temperature range and can be solidified and necrotized for a certain time, so as to attain the goal of local inactivating tissue. Simultaneously, the radiofrequency thermal effect can solidify blood vessels of surrounding tissues to form a reaction zone, so that the reaction zone can not supply blood to tumors to prevent tumor metastasis.

The diameter of the needle body of the traditional ablation needle/radio frequency needle is generally in the range of 1.0-1.9mm so as to ensure that certain strength is convenient to penetrate into deep lesion parts, and the insulating materials of the insulating section of the needle body are mostly sleeves and heat shrinkage tubes. The size is above 0.025mm, and the pressure resistance is above 2000V and within 3500V. However, the features of the sleeve and heat shrink tube can increase the diameter of the entire needle, thereby affecting the use of the electrical needle. In view of this, we provide a medical electrical needle.
