Abstract

The invention discloses a minimally invasive spinal operation channel device for vertebral pedicle fixation. The device comprises a first spinal operation channel device, a second spinal operation channel device and a linkage device. The two ends of the linkage device are linked to the first spinal operation channel device and the second spinal operation channel device respectively to form mutualconstraint fixation relationship of the first spinal operation channel device and the second spinal operation channel device, the first spinal operation channel device and the second spinal operationchannel device each include a guiding needle, an expansion sleeve and an outer sleeve, and the linkage device comprises a lock ring sleeve and a connecting locking device fixed to the first spinal operation channel device and the second spinal operation channel device. The linkage device of the device is more compactly connected with the first spinal operation channel device and the second spinaloperation channel device, the mutual constraint relationship formed between the first spinal operation channel device and the second spinal operation channel device is ensured, the relative position relationship between the first spinal operation channel device and the second spinal operation channel device is ensured, the linkage device is more convenient and rapid to fix, and the operation efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of medical instruments, in particular to a minimally invasive spinal surgery access device for pedicle fixation and a method of use thereof. 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. 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 t...
