An intelligent device for stretching the interspinous processes of the lumbar spine

Abstract

The invention discloses an intelligent device for stretching the interspinous processes of the lumbar spine, which comprises a spreader body, the spreader body includes a spreader mouth, a parallel spreader and a grip handle; it also includes a base, a universal arm and telescopic mechanism, the base is provided with a support arm, and the telescopic mechanism is slidably connected to the support arm through a universal arm; the telescopic mechanism includes a screw mandrel, a screw mandrel sleeve, a reducer and a driver; the screw mandrel Rotationally connected in the screw sleeve, and the extended end of the screw is hinged with one handle of the handle, and the screw sleeve is fixedly connected with the other handle of the handle; the driver is fixedly connected with the screw sleeve And the driver is connected with the screw rod through the reducer, and the screw rod is stretched between the two handles through the rotation of the driver, thereby driving the opening and closing of the opening. The invention realizes precise control of the opening angle between spinous processes, improves intelligence, reduces human operation, and reduces the possibility of artificial injury.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an intelligent device for spreading between lumbar spinous processes. Background technique [0002] Now the incidence of lumbar spondylosis is getting higher and higher. For sedentary people, lumbar spondylosis has gradually formed an occupational disease, lumbar disc herniation, lumbar spinal stenosis and other diseases are becoming more and more common. The current clinical operations include posterior lumbar laminectomy and decompression, lumbar interbody fusion and pedicle fixation. After the laminae of the corresponding segment are removed during the operation, the dural sac needs to be retracted, and the intervertebral space located in front of the dura is treated from both sides of the dura from the back to the front. Most of the above diseases are accompanied by osteophyte hyperplasia at the posterior edge of the vertebral body, which will lead to the narrowing...

AI Technical Summary

Problems solved by technology

[0004] The aforementioned lumbar interspinous process distraction devices have deficiencies. For example, by manually stretching the interspinous processes and relying on experience to control the strength, the angle of distraction cannot be strictly controlled. Improper operation will cause artificial damage, and it is impossible to achieve precise numerical control.

In addition, when the lumbar interspinous process distraction device stretches the interspinous process, it needs to be held to maintain its balance. If the lumbar spinous process is only used to support the balance of the lumbar spinous process distraction device, it will cause serious damage to the lumbar spinous process. certain damage
