Opening device for prone position intervertebrale foramen

Abstract

The invention discloses an opening device for a prone position intervertebrale foramen. The device is characterized by comprising a horizontally arranged bottom plate, a liftable support plate, two stand columns and two pressing plates, the liftable support plate is arranged above the bottom plate, a piston rod of a cylinder is fixed to a connecting plate arranged below the liftable support plate, the bottom end of each stand column is connected with a sliding base which is matched with a rail arranged on one side of the bottom plate, the pressing plates are connected with the stand columns through sliding connectors which can move up and down along the stand columns, and stop pins are arranged between the sliding connectors and the stand columns. According to the opening device for the prone position intervertebrale foramen, the partial body of a patient is raised through the liftable support plate, the two pressing plates are adjusted to be at the two sides of the intervertebrale foramen needing to be enlarged, the portions, at the two sides of the intervertebrale foramen, of the body are pressed through the pressing plates to make the intervertebrale foramen in an opening state, and transforaminal endoscopic spine surgery is completed conveniently under the position of prone.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a device for spreading intervertebral foramina in a prone position. Background technique [0002] Minimally invasive surgery is an inevitable trend in the development of surgery. It is a technology and method for diagnosing and treating diseases in the human body through non-traditional surgical methods with the help of special surgical instruments and equipment such as medical imaging / microendoscope. Iatrogenic trauma is reduced to a minimum for satisfactory outcomes. In the field of minimally invasive spinal surgery, minimally invasive surgery on lumbar intervertebral discs and spinal canals is currently performed by percutaneous puncture from the lumbar intervertebral foramen under the intervertebral foramina. In the minimally invasive transforaminal surgery of the lumbar spine, it is necessary to position the patient to expand the intervertebral foramen o...

AI Technical Summary

Problems solved by technology

For patients in lateral position, it is only necessary to raise the position slightly above the iliac crest on the healthy side, while for patients in prone position, since the intervertebral foramen cannot be enlarged, more bone can only be removed, and the rate of exit nerve root injury Increase
