Positioning equipment for digital spinal surgeries

Abstract

The invention relates to positioning equipment for digital spinal surgeries. The positioning equipment comprises an outer sleeve, wherein a positioning assembly is arranged in the outer sleeve; a positioning needle is arranged at the end head of the positioning assembly; a sensing device is connected with the positioning needle; an observation assembly and a guiding assembly are mounted in the positioning assembly. The positioning equipment can be effectively combined with the conventional digital spinal surgery devices, and the assembling matching degree is high. By adoption of the observation assembly and the guiding assembly, the surgery implementation can be assisted in the positioning period. Due to the existence of an elastic assembly, the positioning efficiency is improved, and accurate acquisition basis is provided for the subsequent digital data processing. The positioning equipment for digital spinal surgeries is simple in structure and convenient to produce.

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
