Microwave Tumor Therapy Instrument(Trolley type)
CHW-MWC1000
The microwave knife water-cooling circulation controller (peristaltic pump) microwave ablation treatment system is integrated with the whole machine, with exquisite design, simple operation and sufficient power. The core components of the therapeutic apparatus are processed by special process with high-performance imported magnetron, 400°C. The output power at high temperature is stable within 2W, and the microwave output stability of the magnetron is internationally leading. The advanced high-voltage switching power supply technology has low energy consumption, high efficiency and wide voltage adaptability (AC190V-250V). The EM filter can effectively filter out interference clutter in the power grid, with high anti-interference and strong safety. It is supplemented with a fuse to ensure stable use of the equipment. The system realizes the integration of the computer platform and the host platform, can realize the layout of multiple USB interfaces and RJ45 network interfaces, and quickly connects the printer, the disk and the hospital network, providing the operator with the greatest convenience and quality assurance. .
Mechanism of inactivation of tumor by microwave energy condensation
■ Under the guidance of B-ultrasound, CT, MR or X-ray, the microwave knife is intervened in the tumor tumor, and the polar molecules in the tissue move at high speed under the action of the microwave field to generate heat. When the temperature rises to 60 °C Above, the protein of the swollen cells denatures and solidifies, causing irreversible necrosis;
■ Inactivated tumor tissue can produce heat shock protein, stimulate the body's immune system, improve the body's immune function, and inhibit the spread of tumor cells;
■ High-energy microwave heat can cause tumor cell P53 and other genetic changes, thereby inducing tumor cell apoptosis
On April 16, 2011, the national initiation meeting of intratumoral immunotherapy and targeted radiotherapy combined with commonly used minimally invasive techniques for the treatment of cancer in the first stage was held in Fuzhong Group.
MWC series cold cycle microwave knife
Cold cycle technology
Advanced water-cooling circulation technology can reduce the temperature of the microwave antenna rod to below 37 °C, prevent scald skin from reducing the pain and improve the safety of surgery.
Bypass temperature measurement technology
Bypass temperature measurement mode can accurately control the extent of swelling and swelling, expand surgical indications, and improve safety.
Double-knife combined technology
For larger swollen, a double knife can be used and inactivated once in situ. The microwave double-knife type is beneficial to increase the damage range, which is different from the single linear 1+1 stacking between the two isolated thermal fields. The technique is that the interaction between the two thermal fields is significantly larger than the equal power, equal time condition, and the single-knife solidification range. Star damage area
