Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a microwave ablation needle suitable for thyroid gland. Background Art

[0002] Microwave ablation needle is mainly used to treat tumor diseases. It is a very thin special needle tube that uses microwave technology to treat tumor tissue. During ablation treatment, the microwave ablation needle is positioned around the tumor and injects microwave heat energy into the surrounding area, so that the tumor tissue is heated and ablated. The needle can also be positioned under image guidance to accurately treat tumor tissue. Therefore, it is an effective tool for non-invasive treatment using microwave technology.

[0003] A patent for a microwave ablation needle suitable for thyroid surgery, with publication number CN219614019U, is available. The needle comprises a handle and a shaft. The handle houses a cooling water tank and a water inlet and outlet pipes connected to the cooling water tank and extending outward from the handle. The handle comprises a gripping section and a connecting section, both connected and non-collinear, which are affixed to the shaft. The gripping sections are substantially parallel to the shaft and are located on either side of the connecting section. A clearance is formed at the connecting section to prevent the handle from contacting the patient's body during thyroid ablation surgery. This utility model improves the efficiency of thyroid microwave ablation procedures and avoids unnecessary harm to patients.

[0004] Although the above-mentioned device can improve the efficiency of thyroid microwave ablation surgery and avoid unnecessary harm to patients, the inventors found that the handle and the needle shaft are integrated, and after the surgery is completed, the entire microwave ablation needle needs to be disinfected, which is extremely inconvenient. Therefore, we have proposed a microwave ablation needle suitable for thyroid. Utility Model Content
