The invention relates to a minimally invasive surgery distraction device and a minimally invasive surgery distraction system, and solves the technical problems that prior spinal minimally invasive surgery distraction devices are difficult to operate, the distraction angle is fixed and cannot be freely adjusted, and the distraction action is not stable enough and is easy to damage muscle tissues. The device comprises a distraction cylinder assembly, a support frame, a base, a threaded driving rod outer sleeve, a light source interface component and a threaded driving rod, the distraction cylinder assembly comprises a left distraction half cylinder and a right distraction half cylinder, the top of the left distraction half cylinder is rotationally connected to the base through a first rotating shaft, the top of the right distraction half cylinder is rotationally connected to the base through a second rotating shaft, the threaded driving rod outer sleeve is connected to the base, the threaded driving rod is matched with the threaded driving rod outer sleeve, and a screw is connected to the top of the threaded driving rod; and the bottom of the threaded driving rod is connected to theleft distraction half cylinder through a first transmission connecting rod, and the bottom of the threaded driving rod is connected to the right distraction half cylinder through a second transmissionconnecting rod. The device is widely applied to the technical field of medical instruments.
Description
technical field [0001] The invention relates to the technical field of minimally invasive spinal surgery, in particular to a minimally invasive surgical distraction device and a minimally invasive surgical distraction system. Background technique [0002] In the technical field of minimally invasive spinal surgery, minimally invasive spinal surgery has the advantages of small incision, less trauma, and quick recovery, which is the development trend of spinal surgery; For intervertebral disc decompression surgery, only a small channel is needed to open the surgical field of view and perform surgical operations. [0003] The invention patent application with the publication number CN110384526A discloses a minimally invasive surgery distraction device and a spreader. However, the spreader is difficult to operate, and the spreader angle is fixed and cannot be adjusted freely; the spreader action is not stable enough. Easy to cause damage to muscle tissue. Contents of the inve...
