Abstract

The invention relates to a radiofrequency ablation needle positioning structure, a using method and a detachable orthopedic guider thereof, the radiofrequency ablation needle positioning structure comprises a guider, the detachable orthopedic guider and a radiofrequency ablation needle, the detachable orthopedic guider comprises a guider body, and the guider body comprises a plurality of guider connecting pieces; each guider connecting piece is of a columnar structure with the section in a sector ring shape, the guider connecting pieces are sequentially enclosed to form a hollow columnar structure, and the guider connecting pieces are connected through detachable structures. The guider body does not need to be separated in the axial direction of the radiofrequency ablation needle as a whole, detachment of the guider connecting piece is not hindered by a wiring handle at the tail end of the radiofrequency ablation needle, the operation speed can be increased, the depth of the radiofrequency ablation needle can be adjusted, and especially for deep protruding tissue, the guider connecting piece can be conveniently detached after the guider body is detached, so that the operation efficiency is improved. And the radiofrequency ablation needle can further extend into the deep part of the tissue, so that the treatment effect can be effectively improved, and the radiofrequency ablation needle has far-reaching medical significance on treatment of the intervertebral disc herniation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a radio frequency ablation needle positioning structure for radio frequency ablation surgery, its use method, and its detachable orthopedic guide. Background technique [0002] Radiofrequency ablation is to precisely output ultra-high-frequency electric waves through a specific puncture guide needle. Through high-frequency oscillations, local biological tissues are generated with local high temperature, which plays a role in thermal coagulation or tissue ablation and shrinkage. It is mainly used in orthopedics. Ablation of tissues such as cervical intervertebral discs and lumbar intervertebral discs. [0003] Radiofrequency ablation is detected in real time under digital subtraction, directly acting on the diseased tissue, the data is accurate to less than 1mm, the whole operation is visible, and will not damage the surrounding normal tissues, organs and nerves, the radio...
