Abstract

The invention belongs to the technical field of medical equipment, and discloses a longitudinal axis rotation mechanism for laser guidance, including a shaft sleeve, a rotating shaft arranged in the shaft sleeve and rotatably connected with the shaft sleeve and connected with the laser-guided puncturing device at one end in the longitudinal direction, and a power generating device connected with the end of the rotating shaft far away from the laser-guided puncturing device and connected with a control system, wherein the rotating shaft sleeve is connected with the laser-guided puncturing device at one end in the longitudinal direction. The invention also discloses a control system for a longitudinal axis rotation mechanism guided by a laser, comprising a power source A, a PLC connected with the power source A, a braking device and a power generating device. The invention controls the rotation of the longitudinal axis rotation mechanism by controlling the running and stopping of the power generating device by a computer, which is simple in operating and accurate in position. The braking device is connected with the power generating device, and the power generating device can be braked in time, so that the angle of laser emission is more accurate.

Description

technical field [0001] The invention belongs to the technical field of medical equipment mechanisms, and in particular relates to a longitudinal axis rotation mechanism and a control system, in particular to a longitudinal axis rotation mechanism and a control system for laser guidance. Background technique [0002] Chemotherapy and radiotherapy are two important methods of tumor treatment. The two methods are carried out at the same time, which can play a synergistic effect and achieve good therapeutic effects. Conventional external radiotherapy and systemic chemotherapy, due to the large side effects, are carried out at the same time, and the adverse reactions are large. It is difficult to implement, but through the minimally invasive way, radioactive particles and chemotherapy slow-release particles are implanted at the same time to realize local radiotherapy and chemotherapy of the tumor. Due to the high concentration of radioactive exposure and chemotherapy drugs in the ...
