Problems solved by technology

Spine surgeons and neurosurgeons have done a lot of research and attempts to prevent laminectomy dural scar tissue adhesion. Anti-adhesion materials emerge in endlessly, but none of them can effectively prevent the formation of hematoma and scar hyperplasia.

Embodiment Construction

[0015] An absorbable septal capsule for preventing epidural scars, comprising: septum capsule body 1 with capsule cavity 2 in septum capsule body 1, filling liquid human body absorbable material 3 in capsule cavity 2, said septum capsule body 1 is a biodegradable capsule body, and a fixed ear 4 is provided on the capsule body 1. In this embodiment, the shape of the capsule 1 filled with the liquid human body absorbable material 3 is slightly thinner from the middle to the edge; the capsule 1 filled with the liquid human body absorbable material 3 has a butterfly shape. The liquid human body absorbable material 3 can be sodium hyaluronate, and the biodegradable capsule is polycaprolactone / polylactic acid capsule.

[0016] Furthermore, the absorbable septum for preventing epidural scars of the present invention has a disc-shaped capsule structure, as attached Figure 1~3 . The central area of ​​the septum is thick and slightly thinner to the periphery. There are fixing ears 4 an...

Abstract

The invention discloses an absorbable sac for preventing epidural scar formation, comprising a biodegradable sac body provided thereon with a cavity filled with an absorbable liquid material and provided thereon with fixing members. The sac body filled with the absorbable liquid material is gradually thinned from the middle to the end, and during the process, the spilled absorbable liquid material (sodium hyaluronate) from the sac can keep the action of preventing and reducing epidural scar formation for a while. Finally, all the components in the sac are degraded into water and carbon dioxide. After the absorbable liquid material is absorbed, the vertebral plate deficient region is replaced by loose tissue, so as to prevent tight adhesion between dural sac and musculus sacrospinalis and prevent a large amount of hyperplastic scar tissue pressing dural sac to induce symptom recurrence.

Description

Technical field [0001] The invention relates to an instrument for preventing postoperative epidural scars on human spinal lamina defect areas in surgical operations, in particular to an absorbable septum that prevents epidural scars. Background technique [0002] In 1934, Mixter and Barr first introduced the early laminectomy to treat traumatic and degenerative disc herniation. Later, this procedure was widely used in the treatment of spinal stenosis, intervertebral disc herniation, spinal tumors, and spinal trauma. It became one of the most commonly used surgical approaches in spinal surgery to obtain thorough decompression and good The surgical field is revealed. However, some patients often experience persistent and recurrent low back and leg pain or other uncomfortable symptoms after surgery, which is clinically called Failedback surgery syndrome (FBSS), with an incidence of 10% to 15%. There are many reasons, but the main reason is the adhesion of the epidural scar. A lar...
