A positioning device for spine digital surgery

Abstract

The invention relates to a positioning device for digital spinal surgery, which includes an outer sleeve, and is characterized in that: a positioning component is arranged inside the outer sleeve, and a positioning pin is arranged at the end of the positioning component. At the same time, a sensing device is connected to the positioning needle, and an observation component and a guiding component are installed in the positioning component. Therefore, it can be effectively combined with the existing spinal digital surgery device, and the assembly matching degree is high. The observation component and the guide component are adopted, which can assist the operation during positioning. Moreover, relying on the existence of elastic components, the positioning efficiency is improved, and accurate collection basis is provided for subsequent digital data processing. Furthermore, the present invention has a simple structure and is convenient for manufacture.

Description

technical field [0001] The invention relates to a positioning device, in particular to a positioning device for digitized spine surgery. 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, there are many meth...

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
