Description
Technical field
The utility model relates to field of medical appliances, more particularly, to the flexible expanding sheath of foramen intervertebrale lens telescopiform soft tissue
Dress.
Background technique
It is well known that the protrusion of the intervertebral disc is a kind of common disease, bring great pain to patients.Treat such disease
Disease.Traditional operation includes vertebral lamina fenestration Nuclectomy and way of escape vertebrae plate resection spinal canal decompression pedicle screw fixation, operation
Wound is big, and bleeding is more, and post-operative recovery time is long, and especially after row internal fixation of spine, the adjacent lumbar vertebrae of Fusion levels is easy to appear
The complication such as regression acceleration, new discomfort is brought to patient.Wherein, interior fixation is with the fixed lumbar vertebrae such as instrument such as screw.
Exist currently on the market diversified forms can bracing type soft tissue expander, the most typical one is casing step by step
Expander is successively worn using a series of hollow metal sleeves, and operative approach channel is gradually expanded.The series sleeve has one
The smallest casing after penetrating soft tissue, then is worn with internal diameter and second casing similar in the sleeve outer, then again with next
A casing is worn, in this way insertion superposition step by step, successively expands approach channel sized, until reaching the mesh of blunt unfurling soft tissue
's.But this casing expander step by step has following defects that
1, the expander casing number of plies is excessive, complicated for operation, is usually expanded to 6.3mm for 3-5 grades, and intussusception component is more,
It will increase operating difficulty and operating time, increase the pain of patient, while also will increase medical treatment cost；
2, soft tissue can pull repeatedly in expander replacement process, be easy to cause tissue incarceration to cause pain uncomfortable, increase
Bleeding probability；
3, most thin expander internal diameter 0.1cm is postoperative to be difficult to clean disinfection and easily cause hereinafter, be difficult to be easy blocking in art
Cross-infection and allergy；
4, existing expander does not have scale, is difficult to estimate depth in art；
5, location guide change in location may be caused in expander replacement process, determining position need to be had an X-rayed repeatedly, cause spoke
Penetrate risk.
6, expander does not design impetus, be easy to cause operational risk when into human body；
7, the fixation of expander size can not extend, the too short operation for being unfavorable for patient of the arm of force.
Therefore, it while how guaranteeing that surgical procedure is safe and effective in Minimally Invasive Surgery, reduces soft tissue injury, reduce behaviour
Make step and the fatigue strength of patient, is a technical problem that technical personnel in the field need to solve at present.
