Problems solved by technology

This method has the following disadvantages: 1. Puncture in three-dimensional space, it is difficult to quickly locate the "safe working triangle" area, especially for beginners, it often takes a long time to locate
2. There are important organs such as large blood vessels and intestines in front of the intervertebral foramen, and the deviation of the puncture needle is likely to cause complications
3. The puncture requires positive and lateral fluoroscopy monitoring, which is cumbersome to operate, and both the operator and the patient increase the X-ray exposure

Abstract

The invention discloses an intervertebral foramen puncture outfit. The intervertebral foramen puncture outfit comprises a puncture needle, a telescopic arm and a guide needle, puncture in three-dimensional space is changed into puncture in a sagittal plane at the outer side of an intervertebral foramen, the intervertebral foramen can be positioned fast and accurately, and the puncture needle can be guided fast and accurately. The intervertebral foramen puncture outfit has the advantages of small trauma, low cost, convenient use and the like, can reduce the number of X-ray examination times, shorten operative time, relieve the pain of a patient, and ensure safe and reliable operation, and is simple in structure, easy to assemble and disassemble, convenient to carry, economical, practical and suitable for final application and popularization.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an intervertebral foramen puncture device. Background technique [0002] Lumbar disc herniation is one of the most common lumbar degenerative diseases. It is caused by partial rupture of the fibrous annulus of the lumbar intervertebral disc, herniation of the nucleus pulposus, and compression of the sciatic nerve, resulting in lower limb pain, numbness, weakness, and even affects bowel movement and sexual function. [0003] Surgical treatment is required for lumbar disc herniation that cannot be relieved by conservative treatment. Conventionally, total laminectomy, hemilaminectomy, or fenestration decompression, as well as decompression, fixation and fusion, are used. Part of the small joint structure, the disadvantage of slow recovery. In 1975, Hijikata used the percutaneous posterolateral approach to remove the nucleus pulposus (Percutaneous lumbar discectomy, PLD)...
