According to the requirements for medical gearboxes, the self coagulation knife gearbox should have high reliability, low noise, and high precision.
For cysts, abscesses, effusions, and blood clots, the SUCO pump at the tip of the suction port sucks into the diseased tissue under the guidance of B-ultrasound. Due to the close fit between the spiral needle core and the inner wall of the punctured tube, the suction port and the discharge port of the SUCO pump are divided into multiple sealed curved surfaces. When the SUCO pump starts, with the high-speed rotation of the needle core and the pressure principle of Archimedes, the vacuum suction will be formed. These sealed spaces on the suction side of the SUCO pump are constantly changing, and the lesion is sucked by the punctured tube. The suctioning position moves along the spiral. The suctioning part will continuously flow to the exhaust port along the axial direction of the needle core. The lesion in the sealed cavity is continuously discharged.
ZHAOWEI micro-drive system can be applied to self coagulation knife, which can improve the noise problem of gearbox and transmission efficiency.
The gearbox for self coagulation knife mentioned above is only shown as a case that is developed for specific customers. It can be customized according to customer requirements.
