Abstract

The invention discloses a spinal puncture guide needle, which is provided with a plurality of passages for radio-frequency electrodes to enter, the inlet end of the passage is located at the tail of the guide needle, and the outlet end of the passage is located at the head of the guide needle; among the plurality of passages Including at least one parallel passage and several inclined passages, the parallel passage and the inclined passage are parallel to each other at the inlet end, the parallel passage is kept parallel to the inlet end at the outlet end, the inclined passage is inclined at the inlet end at the outlet end, and the inclined passage is facing the same direction at the outlet end The sides are inclined, and the inclination angles of each inclined channel are different. The present invention precisely guides the insertion direction of the radio frequency electrode, realizes simultaneous multi-needle precise puncture and ablation of spinal tumors, makes the radio frequency electrode reach the predetermined vertebral body position according to the designed angle direction, can fully cover the entire vertebral body structure, and is disposable Ablation of all tumor tissues in the entire vertebral body achieves the effect of killing tumor cells in the entire vertebral body, shortens the operation time, and relieves the pain of the patient.

Description

technical field

[0001] The invention belongs to the technical field of radio frequency ablation and puncture equipment, in particular to a spinal puncture guide needle. Background technique

[0002] The complexity of the anatomical structure of the spine leads to difficulties in the surgical treatment of spinal tumors. In recent years, more and more scholars have applied radiofrequency ablation technology to the treatment of spinal tumors, and achieved good results, providing a new path for minimally invasive treatment of spinal tumors. new way.

[0003] Radiofrequency ablation is a non-vascular interventional technique. Guided by various real-time imaging techniques, radiofrequency electrode needles are inserted into tumor tissue. Ion vibrations generate frictional heat, which causes thermal damage to a certain range of tumor tissue around the electrode and coagulation and necrosis, achieving the effect of killing tumor cells.
