When medical staff need to treat tumors of patients, the first electrode needle 3 is punctured into a tumor center area, then the first controller 5 is used for controlling the first pulse module 18 to send a first pulse signal to the first electrode needle 3, and the first pulse signal kills tumor cells; when medical personnel need to change different pulse signals, puncture tumour central zone with second electrode needle 4, then utilize second controller 6 control second pulse module 19 to send the second pulse signal to second electrode needle 4, the tumour cell is killed to the second pulse signal, because first pulse module 18 and second pulse module 19 are integrated in same generator 2, the space that occupies on the one hand is less, on the other hand can make medical personnel need not to switch different equipment when changing different pulse signals, thereby can reduce the complexity of tumour operation.
It should be noted that the medical staff may place the main unit 1 on a table or a mobile cart when using the main unit 1.
The first electrode needle 3 includes a monopolar needle, a bipolar needle, a multistage needle (e.g., a cluster needle or a claw needle). The electrode needle comprises a first needle rod, a first handle, a first cable and a first connector. In addition, a take first electrode needle 3 of water-cooling function still contains first water pipe, first peristaltic pump pipe.
The second electrode needle 4 comprises a second needle rod, a second handle, a second water pipe, a second peristaltic pump pipe, a second cable and a second connector. Wherein the second cable can be designed to be permanently connected to the second handle or can be designed to be detachable.
The third electrode needles 9 each include a third needle bar, a second handle, a slider, a PI tube, a third cable, and a third connector.
The generator 2 further comprises a third pulse module 8 integrated with the first pulse module 18 and the second pulse module 19, wherein the first pulse module 18 is a radio frequency pulse module, the second pulse module 19 is a microwave pulse module, and the third pulse module 8 is an irreversible electroporation pulse module; the integrated ablation therapy system further comprises: a third electrode needle 9 connected with the generator 2; and the third controller 20 is used for controlling the third pulse module 8 to send a third pulse signal to the third electrode needle 9.
When medical personnel need to change different pulse signals again, pierce the third electrode needle 9 to tumour central zone, and then utilize third controller 20 control third pulse module 8 to send the third pulse signal to third electrode needle 9, the third pulse signal kills tumour cell, because third pulse module 8 and first pulse module 18 and second pulse module 19 are integrated in same generator 2, on the one hand further reduce the space that occupies, on the other hand can make medical personnel need not to switch different equipment when changing different pulse signals, thereby can further reduce the complexity of tumour operation.
The generator 2 is made of third generation power semiconductor devices such as GaN, SiC, and the like.
The first pulse signal emitted by the first pulse module 18 can perform Radio Frequency Ablation (RFA), and the principle is that when the current frequency is high (> 100kHz), positive and negative ions in the tissue can move rapidly, and friction is generated between the positive and negative ions and other molecules, ions and the like in cells, so that the temperature of a diseased region is raised, and heat is diffused and conducted outwards. When the temperature exceeded 60 ℃, the cells immediately died. And the heat resistance of the tumor cells is poorer than that of normal cells, and the tumor cells begin to die when the temperature exceeds 42 ℃. Radiofrequency ablation is commonly used for soft tissue tumors with a diameter of less than 3cm, including liver cancer, lung cancer, breast cancer, thyroid nodules and the like. When the RFA system is used, a single or a plurality of first electrode needles 3 are inserted into a lesion, and a host 1 generates a radio frequency signal and transmits the radio frequency signal to a human body through the first electrode needles 3. The typical RF ablation frequency is 200-500kHz and the power is 100-400W. The radiofrequency ablation has the advantages of wide adaptation diseases, thin needle and small wound; the disadvantage is that the tissue impedance is greatly affected and the blood flow can carry away part of the heat (also called "heat sink effect"), resulting in poor predictability of the size and shape of the ablation region.
The second pulse signal emitted by the second pulse module 19 can be used for Microwave ablation (MWA), and the principle is that a second electrode needle 4 is punctured into the central area of the tumor, a 1 mm-sized micro Microwave oven is arranged on the needle point of the second electrode needle 4, and a Microwave field is released to enable water molecules in the tissue to rotate at a high speed and rub to increase the temperature, so that the tumor cells are necrotized when the temperature exceeds the tolerance temperature. The common microwave frequency is 2450MHz, the power is 40-120W, and the indication is similar to that of radio frequency ablation. Compared with RFAs, MWAs have the advantages of fast ablation speed, less "heat sink effect" and better predictability of the ablation area.
The third pulse signal from the third pulse module 8 can be used for Steep pulse or irreversible electroporation (IRE), which is based on the principle that a permanent nanopore is generated on a cell membrane by a high-intensity short pulse, and the cell homeostasis is disturbed to cause apoptosis. Unlike RFA and MWA, cell death following IRE is apoptosis (programmed cell death) rather than necrosis (cell damage, destruction of cells by self-enzymatic action). Similar to RFA ablation, at least two third electrode needles 9 are punctured to the periphery of a tumor when using an IRE system, and then an ultrashort pulse voltage is applied to the third electrode needles 9 through the host 1 to generate a high-power pulse electric field to kill tumor cells. The usual pulse length is 1-100us and the voltage peak is several kilovolts. IRE has the advantages of tissue selectivity, no damage to nerves, no heat sink effect, short ablation time, clear boundary, and capability of activating human immune response; the defects are that the needle arrangement time is long, and patients with heart diseases and patients with electronic equipment or metal parts planted in a focus area are not suitable for the needle arrangement. IRE is indicated for liver, lung, pancreas, prostate and other solid tumors, and has unique advantages for tumors near the hepatic portal region, bile ducts of the gall bladder, pancreas, ureter.
