[0002] Cold circulation microwave ablation needle is another name for cold circulation microwave knife. It is the crystallization of microwave technology applied to the field of medical treatment. Cold circulation microwave ablation needle is not a needle, but a very thin radiating antenna. The specific method is: under the guidance of B-ultrasound or CT, the ablation needle is directly punctured into the tumor site. The polar molecules in the tissue move at high speed under the action of the radio frequency field, rub against each other to generate heat, and quickly heat up in the tumor. When the temperature rises to about 60 degrees Celsius, the cancer cell protein denatures and coagulates, leading to irreversible necrosis. At the same time, the impact on other tissues is very small, which improves the patient's immunity and inhibits the spread of tumor cells. Ablation needles are widely used in the treatment of liver cancer, lung cancer, uterine fibroids, bone cancer, kidney cancer, pancreatic cancer, thyroid tumors, hypersplenism, etc. due to their advantages such as fast heating, strong tissue penetration, multi-point ablation can be performed simultaneously, large ablation range, real-time temperature monitoring, and definite efficacy.

[0044] Reference Figure 8 In the initial state, the length of the circular card plate 1 721 is smaller than the length of the circular card plate 2 611 . By setting the length relationship between the circular card plate 1 721 and the circular card plate 2 611 , the flow of the solution in the first chamber 32 and the second chamber 62 can be controlled.

[0045] Reference Figure 1-3A temperature detector for real-time detection of the patient's body temperature is fixedly arranged on the outer wall of the shell 1. By setting the temperature detector on the shell 1, the device can detect the patient's body temperature in real time when in use, thereby ensuring the real-time health of the patient during treatment.

[0046] The specific solution is as follows: when using the device, the staff first inserts the needle rod 2 on the device into the patient's body, and through the slide groove 71 set on the shell 1 and the plug 1 72 slidably connected to the slide groove 71, when the staff needs to adjust the position of the plug 1 72, they rotate the adjustment shell 75, and through the internal thread set on the adjustment shell 75, drive the limit block 73 on the adjustment shell 75 to move, and the limit block 73 can drive the plug 1 72 to move with the movement. When the adjustment shell 75 is rotated in the reverse direction, the reverse movement of the plug 1 72 is simple and convenient. The trachea 1 31 set in the first chamber 32 and the trachea 2 33 set in the second chamber 62 can realize the storage of different solutions and avoid the mixing of different solutions. It appears that the circular card plate 1 721 set on the plug 1 72 and the circular card plate 2 611 on the plug 2 61 can achieve that in the initial state, the circular card plate 1 721 can block the gap between the soft shell 1 5 and the soft shell 2 6, and as the plug 1 72 and the plug 2 61 move, the connection between the groove 8 chamber set on the soft shell 1 5 and the soft shell 2 6 is controlled, so as to control the flow of the solution in the first chamber 32 and the second chamber 62 and control the discharge ratio of the solution in the two chambers. When the connecting rod 722 moves, the pressing plate 97 fixedly connected to the ring 91 moves, and the moving pressing plate 97 can press the squeezing plate 96 to move, and the moving squeezing plate 96 squeezes the soft shell 1 5 in the device to control the flow of the solution in the second chamber 62.
