Description

technical field

[0001] The invention relates to the field of medical instruments, in particular to a pedicle-fixed spinal operation channel device and a method for using the same. Background technique

[0002] The spinal surgery channel device is a common instrument in minimally invasive spinal surgery. The position of the implanted nail channel tube in the spinal surgery channel device on the human body is determined by X-ray fluoroscopy and must be kept stable. Any accidental loosening or displacement means Therefore, the fixation of the spinal operation channel becomes the key to the success of the operation.

[0003] In the prior art, the fixing methods of the spinal operation channel device include: manual hand support method, which requires medical assistants to hold the working channel all the time during the whole operation without shaking. Change; bed frame fixation method, including a set of more complicated bedside fixation frame, one end of the fixation frame is...
