Description

Technical Field

[0001] The utility model relates to the field of ablation needles, in particular to an ablation needle with a pit and an operating frame. Background Art

[0002] After the ablation needle is used to puncture the tumor, high temperature is generated, causing cancer cells to necrotize. The temperature of the needle tip in the patient's body is high, and the heat conducted by the sheath at the upper end of the needle may melt the sheath, resulting in harmful substances remaining in the patient's body. After the tip of the needle enters the patient's body, the specific position of the needle and the contact between the end of the needle and the position to be operated are observed through imaging. During this process, the image of the entire needle body is the same color, and the extent and position of the needle body in the body are judged by observing the tip of the small image and checking the scale at the operating end. This does not allow for a good observation of the length of the needle body in the body, and during this process, it is necessary to ensure that all characteristics of the patient are normal, and blood samples are taken for testing. The use of the ablation needle will hinder the puncture operation space, especially when the needle core, guide wire, and catheter are replaced, and the small joint is not easy to operate.
