Description

Fishhook type soft tissue expansion sleeve for intervertebral foramen formation

Technical Field

The utility model relates to a soft tissue expansion pipe technical field specifically is a fishhook type soft tissue expansion sleeve pipe for intervertebral foramen shaping.

Background

The curative effect of the intervertebral foramen mirror operation is similar to that of the traditional windowing and intervertebral disc mirror, but the intervertebral foramen mirror operation has better advantages than the traditional windowing and MED in the aspects of safety, accuracy, traumatism, recovery time, complications and the like, and becomes a mainstream technology for treating the isosceles vertebra diseases such as lumbar intervertebral disc protrusion and lumbar side recess stenosis. In 1997, Yeung et al developed a percutaneous spinal endoscopy YESS technique, which was not used for intervertebral foramen formation, had relatively narrow indications, and was mainly used for inclusive disc herniation or partial posterior longitudinal sub-ligament type disc herniation, and was unable to treat herniation or dissociative lumbar disc herniation; in 2002, Hoogland et al developed the TESSYS technology, and the working cannula is placed after intervertebral foramen formation, so that the working cannula can be applied to prolapse and free lumbar disc herniation, and the indication of endoscopic surgery is obviously expanded. In recent years, the operation approach is improved through sufficient intervertebral foramen forming, the percutaneous spinal endoscope is also used for treating lumbar spinal stenosis, and the adaptation diseases of endoscopic operations are further expanded, and the intervertebral foramen forming is a core technology of the percutaneous spinal endoscope and is a foundation for the technical development and progress of the percutaneous spinal endoscope.

Applied to soft tissue expansion sleeve pipe in intervertebral foramen plasty, present soft tissue expansion sleeve pipe mainly is circular blunt nosed expansion sleeve pipe, and circular blunt nosed expansion sleeve pipe can only expand the soft tissue simply, can't effectively protect export nerve root and intervertebral foramen outer soft tissue, more can not stably be fixed in articular process, is unfavorable for removing to articular process sclerotin.
