Microwave ablation needle rod 13 is through and is provided with microwave transmission line 21 in, and needle body 2 left side is provided with second handle 18, and second handle 18 bottom fixedly connected with cryoablation needle rod 17, and cryoablation needle rod 17 bottom fixedly connected with cryoablation needle rod 17, and cryoablation needle rod 17 top is connected with cryogenic source equipment (such as liquid nitrogen tank, helium compressor etc.) of cryogenic system through special pipeline, to obtain low temperature cold source.
[0032] Referring to Figures 1-4The outer ring of the miniature camera 5 is provided with an illuminating lamp ring 6, and the illuminating lamp ring 6 is fixedly connected with the inner wall of the mounting groove 4. The illuminating lamp ring 6 is an LED lamp, and the light is cold light. The bottom of the transmission line 8 is connected with the miniature camera 5, and the top of the transmission line 8 is fixedly connected with the display screen 9. The display screen 9 is arranged on the outer side of the needle handle 1, so that the real-time image can be synchronously transmitted to the display screen 9, and the doctor can intuitively observe the position of the needle tip, and precise operation is realized. The channel outlet 10 is arranged on the right side of the puncture head 3, and the top of the channel outlet 10 is communicated with the targeted intervention channel 11, so that the limiting sleeve 12 of the targeted intervention channel 11 plays a limiting role. The puncture needle penetrates through. The top of the needle handle 1 is fixedly connected with the limiting sleeve 12, and the limiting sleeve 12 corresponds to the targeted intervention channel 11. The outer end of the microwave transmission line 21 is fixedly connected with the microwave generator 16, and the microwave generator 16 is arranged outside the microwave ablation needle rod 13. The model of the microwave generator 16 is Windfreak SynthHD PRO. The microwave generator 16 can convert electric energy into microwave energy of a specific frequency (usually 2450MHz or 915MHz) through an internal electronic oscillation circuit (such as a magnetron, a klystron, etc. Core components). In this process, the electrons in the circuit oscillate at high frequency under the action of a strong magnetic field and an electric field, producing high-frequency electromagnetic waves (i.e. microwaves). The microwave energy generated by the microwave generator 16 is transmitted to the microwave needle head 15 through the microwave transmission line 21. The outer part of the needle body 2 is provided with uniformly distributed scale lines 20, which can help medical staff to master the puncture depth. The bottom of the microwave transmission line 21 is fixedly connected with the microwave needle head 15, so as to transmit the microwave energy to the microwave needle head through the microwave transmission line 21.
[0033] Working principle: During the puncture operation, the medical staff holds the needle handle 1, and the puncture head 1 at the bottom of the needle body 2 is aimed at the target site. The miniature camera 5 in the left side installation slot 4 of the puncture head 3 plays a key visual role, and the outer circle of the illuminating lamp ring 6 provides sufficient illumination to ensure that the miniature camera 5 can clearly capture the images of the puncture path and the target area. These images are transmitted in real time to the display screen 9 outside the needle handle 1 through the transmission line 8 in the line slot 7, so that the medical staff can directly observe the internal situation and achieve accurate positioning. At the same time, the evenly distributed scale lines 20 on the outside of the needle body 2 can help the medical staff to master the puncture depth, further improving the positioning accuracy. When targeted interventional therapy is needed, the targeted interventional channel 11 plays an important guiding role, its bottom is communicated with the channel outlet 10 on the right side of the puncture head 3, and the top corresponds to the limiting sleeve 12 on the top of the needle handle 1, which ensures that the interventional instrument can enter accurately. If microwave ablation therapy is used, the medical staff holds the first handle 14, sends the microwave ablation needle rod 13 through the targeted interventional channel 11, so that the microwave needle head 15 reaches the target position, and the microwave energy generated by the microwave generator 16 is transmitted to the microwave needle head 15 through the microwave transmission line 21. When the microwave needle head 15 contacts the target tissue, the microwave energy released by it will cause the high-frequency vibration of the polar molecules (such as water molecules) in the tissue, and the mutual friction between the molecules will generate a large amount of heat, so that the local tissue temperature rises rapidly to above 60℃ in a short time. High temperature will cause the target tissue cells to denature and coagulation necrosis, and at the same time destroy the blood vessel structure in the tissue, block the blood supply, and further promote the necrosis of the diseased tissue. Realize microwave ablation of the target tissue. If cold ablation therapy is selected, the medical staff holds the second handle 18, sends the cryoablation needle rod 17 through the targeted interventional channel 11, and lets the cryoablation needle head 19 reach the target area. At this time, the cryoablation needle head 19 contacts the target tissue. The cryogenic source device (such as a liquid nitrogen tank, a helium compressor, etc.) of the cryogenic system will be connected with the relevant channels inside the cryoablation needle rod 17 through special pipelines, and low-temperature refrigerant (argon) will be delivered to the cryoablation needle head 19. The low-temperature refrigerant changes phase (such as from liquid to gas) at the cryoablation needle head 19, which will absorb a large amount of heat, causing the temperature of the cryoablation needle head 19 to drop sharply. This low temperature will quickly conduct to the target tissue in contact with it, causing the water in the target tissue to freeze rapidly to form ice crystals. The formation of ice crystals will destroy the structure of cells, causing cells to dehydrate and protein denaturation. At the same time, low temperature will also affect the blood circulation of the target tissue, causing local ischemia and hypoxia, further exacerbating cell damage and death. When the target tissue is fully frozen, the other channel in the cryoablation needle rod 17 is used to introduce a warming medium (helium) to raise the temperature of the cryoablation needle head 19, so that the frozen tissue is thawed. In the repeated freeze-thaw cycle process, the target tissue will be completely destroyed, thereby achieving the purpose of ablation therapy, and the targeted interventional channel 11 can also slowly inject targeted therapy drugs into it through the drug injection instrument, and the drugs act directly on the target tissue through the channel outlet 10, realizing targeted drug therapy.
