Embodiment Construction
[0056] Below at first illustrate the structure of each unit apparatus that forms this set of apparatus in conjunction with accompanying drawing:
[0057] Locate channel 1, see figure 1 , the front end has a blunt head 1-1, the tail has a T-shaped handle 1-2, and the inner diameter is 0.35cm. It is used to bluntly separate the deep fascia, from the posterior rectal space through the front of the sacrum, along the midline of the sacrum to the entry point of the sacral surgery, that is, the intersection point of the central axis of the fifth lumbar vertebra and the sacral surface, and is positioned close to the sacral surface.
[0058] The guide pin 2, referring to Fig. 2, has a diameter of 0.34 cm and a sharp front end. It is used to pass through the middle hole of positioning channel 1, puncture the sacrum and the upper endplate of the sacrum from the sacral surgical access point, pass through the lumbar 5 sacral 1 intervertebral space, and reach the lower endplate of the lumb...

Abstract
The present invention provides a set of internal fixing surgical instruments for minimally invasive lumbosacral anterior fusion operation, including a series of components of a positioning channel, a guide pin, a main channel, a drilling head, an intervertebral processor with a self-adjusting rotary cutter head, a water-injection style intervertebral cleaner, a thick wall channel sleeve, a fixing channel, a fixing screw, a screw fastening device, a screw end cap, an end cap fastening device etc.; in view of the abnormal function of the intervertebral structure, intervertebral instability, nerve root involvement and other lesions of the lumber vertebra section caused by lumbar intervertebral DDD, the application of the instruments can reduce the injuries and damages to the adjacent soft tissues and the spine stable structure to the maximum extend based on the smooth completion of the surgical operations of disc excision, intervertebral space processing, intervertebral space expansion, intervertebral fusion, internal fixation and so on, at the same time, the present invention can also reduce the postoperative complications, shorten the hospital stay and reduce the hospitalization cost to the maximum extend, thereby improving the operation effects and the satisfaction to the maximum extend.
Description
technical field [0001] The invention relates to an intervertebral fusion and internal fixation surgical instrument for spinal surgery, more specifically, an intervertebral fusion internal fixation surgical instrument for percutaneous percutaneous transsacral anterior approach for treating the motion segment of spinal lesions. Background technique [0002] Degenerative disc disease (DDD) refers to the biological degeneration of the intervertebral disc tissue under the combined action of various reasons, which leads to changes in the mechanical properties of the intervertebral disc, resulting in corresponding changes in the adjacent bone joints and ligaments, resulting in instability of the spine. Syndrome of corresponding clinical symptoms and signs. According to its etiology, treatment can be divided into non-surgical treatment and surgical treatment. [0003] Traditional lumbar fusion includes anterior lumbar interbody fusion (ALIF), posterior lumbar interbody fusion (PLIF...
