Abstract

The invention discloses a positioning device of a percutaneous lumbar intervertebral disc operation path and a positioning method. The method comprises the following steps: A, fixing an underframe on the small of the back of a human body; B, projecting the human body from the side surface of the human body, adjusting the relative position between a sliding rack and the underframe according to operation position, and locking by a first locking position; C, adjusting an angle between a left conduit and a right conduit as well as between a left side frame and a right side frame, and locking by a fourth locking device and a fifth locking device; and D, sliding the left side frame and the right side frame relatively to the sliding rack, adjusting the position relatively to the sliding rack, and locking by the second locking device and the third locking device after being adjusted to the proper position. The invention is convenient to position, effectively shortens operation time and reduces patient pain.

Description

technical field [0001] The invention belongs to the field of intervertebral disc surgery, and in particular relates to a positioning device and a positioning method for a channel for percutaneous lumbar intervertebral disc surgery. Background technique [0002] Percutaneous lumbar disc surgery includes percutaneous lumbar discectomy, percutaneous lumbar disc fusion, percutaneous laser lumbar disc decompression, percutaneous lumbar intradiscal hyperthermia and percutaneous transforaminal endoscopic nucleectomy , Under the premise of meeting the indications, compared with the posterior lumbar discectomy, they have the advantages of good curative effect, high comfort, no damage to the bone and ligament of the spine, no entry into the spinal canal, and no influence on the stability of the spine. But on the other hand, in the process of percutaneous lumbar intervertebral disc surgery, the positioning is difficult, the operation process is complicated, and the operation time is lo...
