A digital spinal surgery device based on micro-gap positioning

Abstract

The invention relates to a spinal digital surgery device based on micro-gap positioning, which includes a bearing platform, a controller is arranged on the bearing platform, an X-axis guide rail is arranged on the bearing platform, and a moving assembly is slidably connected to the X-axis guide rail. Yes: The mobile component is provided with a Y-axis guide rail, a column is slidably connected to the Y-axis guide rail, a Z-axis guide rail is distributed on the column, a beam is slidably connected to the Z-axis guide rail, a universal interface is provided on the beam, and a universal interface is connected to a The navigation robot arm and the decompression combination robot arm are connected with a locator on the navigation robot arm. In this way, it can assist the implementation of spinal surgery, especially to help medical staff perform spinal fractures, spinal tumors, scoliosis, intervertebral disc herniation, spinal stenosis, spondylolisthesis and other spinal surgery operations. The overall application range is wide, the positioning accuracy is high, the operation is simple, safe and reliable.

Description

technical field [0001] The invention relates to an operation device, in particular to a spinal digital operation device based on micro-gap positioning. Background technique [0002] At present, thousands of patients with spinal fractures, spinal tumors, scoliosis, intervertebral disc herniation, spinal canal stenosis, and spondylolisthesis undergo various spinal operations every year, such as laminectomy and decompression, transvertebral arch Root screw fixation, vertebroplasty, nucleus pulposus removal, etc. Since important tissues such as the spinal cord, blood vessels, and organs are located in the spinal canal or around the vertebrae, misoperation such as pedicle screw insertion penetrating the pedicle bone cortex, and nucleus pulposus forceps entering the abdominal cavity may lead to disastrous consequences such as paralysis or even death . Therefore, accurate positioning and precise operation are of great significance in the field of spinal surgery. At present, ther...

Problems solved by technology

Using the principle of computer-aided navigation or using high-end imaging equipment for guidance, not only the cost of radiation exposure during the operation is also very expensive

(5) Others Some other positioning methods in the prior art, such as frame positioning, have been eliminated due to innovation

The stereotaxic surgical system based on CT and MRI scans in a specific bottom frame has high registration accuracy by using the scanning mask, but it can only be performed in the CT or MRI room, and the application is limited; the use of body surface marker registration cannot guarantee intraoperative and surgical procedures. The positioning accuracy is low due to the same anterior body position and skin movement, so it can only be used for orthopedic surgery that does not require high operating accuracy
