Abstract

The invention relates to a rotary resection operation device. The rotary resection operation device comprises an outer sheath tube (1), an inner sheath tube (2), a water inlet (3), a water outlet (4)and a cable (6). The rotary resection operation device further comprises a rotating shaft (7) and a motor (501), wherein the rotating shaft (7) can be driven by the motor (501) to rotate, and a resection ring is arranged at the tail end of the rotating shaft (7). The outer sheath tube (1) and the inner sheath tube (2) are nested with each other, and the rotating shaft (7) is positioned in the inner sheath tube (2).

Description

technical field [0001] The invention belongs to the technical field of medical equipment. In particular, it relates to a rotary resection operation device with high resection efficiency and high accuracy and an operation method thereof. Background technique [0002] In 1929, McLean first studied and proposed the principle of electrosurgery. Its first application was the resectoscope in the 1930s, after the introduction of the electrosurgical generator device developed by Bovie and Cushing. In the earliest resectoscopes, a cutting ring was mounted on a fitted cystoscope, and a high-frequency electrosurgical generator was able to deliver cutting and coagulation currents. [0003] In the following decades, the technology of resectoscope underwent a comprehensive innovation, including high-frequency electric knife, better resectoscope and loop materials, better perfusion, etc., but the technical principle behind it is still the same as that of the 1980s. The same as before, i...
