Transforaminal endoscope operation positioning method based on X-ray machine

Abstract

The invention belongs to the technical field of puncture point positioning for interventional surgery, and in particular relates to an X-ray machine-based positioning method for intervertebral foramina endoscopic surgery. The method includes the following steps: 1). Under the above-mentioned lateral perspective, the positioning needle and its extension line pass through the upper articular process tip and the posterior upper edge of the next vertebral body on the affected side where the intervertebral disc space is located to obtain lateral positioning. 2), under anteroposterior fluoroscopy, pass the positioning needle through the tip of the upper articular process on the affected side where the intervertebral disc space is located and the midpoint of the upper edge of the next vertebral body to obtain the anteroposterior positioning line; 3), the above-mentioned lateral position The intersection of the positioning line and the positive positioning line on the patient's body surface is the body surface puncture point. The method has the advantages of simplified puncture process, high puncture point positioning accuracy, reliable and easy operation, can effectively improve the safety and success rate of surgery, and effectively improve the radiation exposure of operators and patients at the same time.

Description

technical field [0001] The invention belongs to the technical field of puncture point positioning for interventional surgery, and in particular relates to an X-ray machine-based positioning method for intervertebral foramina endoscopic surgery. Background technique [0002] In recent years, transforaminal endoscopy has become a trend in the treatment of lumbar disc herniation, which has the advantages of obvious curative effect, less damage, safety and quickness. The intervertebral foramina technique uses the physiological structure of the intervertebral foramen to percutaneously puncture the lumbar spine with a puncture needle, thereby grinding and shaping the superior articular process, and then inserting the working pipeline into the spinal canal, after which the endoscope and surgical instruments can pass through the spine. The working pipeline directly enters the spinal canal to facilitate the treatment of diseased tissues. With the development of transforaminal endosc...

Problems solved by technology

However, if a physical device requires high precision, it will inevitably bring about a sudden increase in cost, and the high purchase cost will inevitably be attached to the economic cost of the patient

More importantly, since the external instrument must be placed outside the patient's body during operation, the patient's slight movement during the operation will lead to inaccuracy of the entire positioning operation, which will greatly reduce the positioning accuracy of the actual interventional operation , so that the surgical effect and success rate are often unsatisfactory
