Digital spinal surgery device based on micro clearance positioning

Abstract

The invention relates to a digital spinal surgery device based on micro clearance positioning. The digital spinal surgery device comprises a bearing platform, wherein a controller is arranged on the bearing platform; an X-shaft guiderail is arranged on the bearing platform; a mobile assembly is connected with the X-shaft guiderail in a sliding manner. The digital spinal surgery device is characterized in that a Y-shaft guiderail is arranged on the mobile assembly; a stand column is connected with the Y-shaft guiderail in a sliding manner; a Z-shaft guiderail is distributed on the stand column; a cross beam is connected with the Z-shaft guiderail in a sliding manner; a universal interface is arranged on the cross beam; a navigation robot arm and a decompression combined robot arm are connected with the universal interface; a positioner is connected with the navigation robot arm. Therefore, the implementation of the spinal surgeries can be assisted and the medical personnel can be helped to conduct spinal surgeries of spine fracture, spine tumor, spine scoliosis, intervertebral disc protrusion, spinal canal stenosis, spondylolisthesis and the like. The digital spinal surgery device is wide in application range, high in positioning precision, convenient to operate, 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
