Description

Technical Field

[0001] The invention relates to the technical field of electrode needle processing, and in particular to a needle tip processing device for a single-side needle of a radio frequency ablation electrode needle. Background Art

[0002] At present, the ablation range of existing radiofrequency ablation needles is spherical or ellipsoidal. However, in clinical applications, it is often the case that only one side needs to be ablated, while the other side is tissue or blood vessels that are not desired to be ablated. This situation is especially common in lung nodule ablation. The spherical or ellipsoidal ablation range is difficult to cope with such situations, which greatly increases the difficulty of surgical positioning and adds risks to patients. Therefore, clinical needs hope to develop a radiofrequency ablation needle that can cope with such situations, and achieve the purpose of accurately controlling the ablation range based on the advantages of minimally invasive treatment. Conventional types of radiofrequency ablation needles are difficult to solve the problem of needing ablation on one side. The main reason is that the working front end of conventional types of radiofrequency ablation needles is completely exposed, and the ablation range is fixed to a spherical or ellipsoidal shape. If you want to adjust the ablation range, you need to shield the working end. For this reason, the radiofrequency needle for half-side ablation can be made to solve the problem. However, the processing equipment currently used has the following technical problems:

[0003] 1. The ablation needle is manufactured by casting a hollow needle, slotting one side and beveling the needle tip. The accuracy of manual positioning is average, and it is inconvenient to automatically position it. There is a lack of control structure for automatically aligning the needle tip.

[0004] 2. The efficiency of needle placement is low and there is a lack of auxiliary positioning and placement structure;

[0005] 3. Lack of precise processing mechanism makes it inconvenient to perform conformal positioning processing as required. Summary of the invention
