Abstract

The invention discloses a multifunctional preoperative target positioning device for a foramen intervertebrale mirror. The device comprises a positioning column, a horizontal length measuring rod andan angle measuring rod, wherein the horizontal length measuring rod and the angle measuring rod can slide on the positioning column, and the horizontal length measuring rod and the angle measuring rodcan rotate circumferentially along the positioning column; the angle measuring rod can swing freely; scales are arranged on the horizontal length measuring rod; and the horizontal length measuring rod can be bent. According to the multifunctional preoperative target positioning device for the foramen intervertebrale mirror, target positioning, scale measurement and angle measurement are integrated, and an operation target, an operation approach and the placement direction of a working sleeve can be determined through one-time perspective, so that operation accuracy is improved, the preoperative preparation time is saved, and the ray exposure time of an operator and a patient is shortened.

Description

Technical field [0001] The invention relates to the technical field of surgical positioning devices, in particular to a multifunctional preoperative target positioning device for foraminal mirrors. Background technique [0002] In the operation of lumbar disc herniation and other spine parts, the traditional lumbar disc herniation nucleus pulposus removal operation is an open operation, which will bring greater pain and trauma to the patient, and has a long recovery period and slow wound healing. In recent years, with the development of science and technology, the use of endoscopes to perform spinal surgery has become a common method under minimally traumatic conditions. However, when performing operations on the spine such as lumbar disc herniation, proper puncture is required. The puncture point and the correct puncture direction are the keys to the success of the operation, and the incidence of postoperative complications will be significantly reduced. [0003] Generally, durin...
