Puncture needle directional navigation device

Abstract

The invention discloses a puncture needle directional navigation device for lumbar discectomy under a percutaneous endoscope. The puncture needle directional navigation device comprises a base, a puncture needle, puncture needle sagittal plane laser emitters and puncture needle coronal plane laser emitters; the puncture needle is used for routine operative puncture, the base is provided with the four laser emitters, the laser emitters can emit visible lasers, the coronal planes are red light, the sagittal planes are green light, and when a needle head is placed on the skin, the lasers with different colors in linear shapes on the two planes can be seen; the lasers emitted by the puncture needle sagittal plane laser emitters are used for coinciding with drawing lines on the sagittal plane of an incision before an operation to determine the puncturing direction of the puncture needle on the sagittal plane; the lasers emitted by the puncture needle coronal plane laser emitters are used for coinciding with the drawing lines on the sagittal plane of the incision before the operation to determine the puncturing direction of the puncture needle on the coronal plane; after the puncturing directions of the two planes are determined, the puncture needle can be accurately navigated into the intervertebral disc. The puncture needle directional navigation device has the advantages that the incidence rate of errors in puncturing directions is effectively reduced, and the operative time is shortened.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a puncture needle direction navigation device. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] Percutaneous endoscopic lumbar nucleus pulposus extraction (PELD) surgery is a surgical method for the treatment of various spinal diseases (lumbar disc herniation, lumbar spinal stenosis) that has emerged in recent years. It has the advantages of small incision, small trauma and long operation time Short, good postoperative effect and many other advantages. But there are also disadvantages. For example, the preoperative incision needs to be precisely positioned, otherwise it will lead to difficult operation during the operation; there are many perspectives during the operation, and the operator needs to withstand X-ray radiation several times high...

AI Technical Summary

Problems solved by technology

This method has its disadvantages: because the lateral position only determines one point of the target intervertebral disc, so the direction of the guide needle is different, so the needle insertion point is different, and a lot of needle insertion points can be made, which are relatively unfixed

[0005] However, in actual operation, it is found that although the needle insertion point is easy to grasp, the direction of needle insertion often deviates due to the need to overlap the straight lines of the two planes. The surgeon often needs to observe the two planes at the same time with the naked eye and adjust the needle insertion direction many times. The puncture can only be successful, which increases unnecessary fluoroscopy time and times
