Three-dimensional positioning guiding gauge for puncture and using method thereof

Abstract

The invention relates to a three-dimensional positioning guiding gauge for puncture, which consists of a master member and a suite. The master member and the suite have three edges; a face between a first edge and a second edge is a front face, and a face between the second edge and a third edge is a lateral face; the master member and the suite are divided into two symmetrical and equal ends through a zero line, and can be used bidirectionally; and the suite is sleeved on the master member, the inner face of the suite is attached to the outer face of the master member without gaps, the front face and lateral face of the suite correspond to those of the master member, and the suite can slide on the master member back and forth. The three-dimensional positioning guiding gauge is used for improving puncture success rate and accuracy and avoiding puncturing repeatedly to reduce exposure times and radiation damage; and puncture side-open distance, angle degree and puncture depth are accurate further, so that surgical doctors have the visual sense of space in the puncture operation, and the puncture success rate and accuracy are improved. The three-dimensional positioning guiding gauge is suitable for the use and reference of doctors in departments of orthopedics, spine surgery, pain treatment, intervention and neurology, and has the advantages of simple structure, convenient use and popularization, wide application and low manufacturing cost.

Description

technical field [0001] The invention relates to a diagnostic appliance, in particular to a diagnostic appliance for human body puncture. Background technique [0002] The most commonly used approach for lumbar disc puncture is the lateral posterior approach, which is also the puncture approach in the "safe triangle". [0003] Safety triangle area: After the lumbar spinal nerve root passes through the dural sac, the spinal canal runs obliquely forward and downward around the intervertebral disc fibrous ring below the pedicle, and forms a triangle with the upper edge of the lower vertebral body and the anterolateral surface of the superior articular process The area, in which there are no important nerves and blood vessel structures out of shape, is an ideal way for intervertebral disc puncture. [0004] Disadvantages of puncture through the safe triangle area are: angled puncture, long puncture path, and difficult to grasp the direction of needle insertion; due to the obstru...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of puncture through the safe triangle area are: angle puncture, long puncture path, difficult to grasp the direction of needle insertion; due to the obstruction of the iliac crest wing and the limitation of the sacral angle, the success rate of lumbosacral intervertebral disc puncture is not high

Those with little puncture experience need repeated punctures and multiple exposures to X-rays, causing unnecessary damage to patients
