Micro-wound lubosacral spine anterior fusion inner fixation surgical instrument and using method

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...

AI Technical Summary

Problems solved by technology

Although the current minimally invasive lumbar fusion has greatly corrected the shortcomings of traditional surgery, it still inevitably causes a certain degree of damage and destruction to the paravertebral soft tissue and stable structures of the spine.
