AI Technical Summary

Technical Problem

The existing puncture needles used for spinal vertebral shaping surgery have insufficient puncture accuracy and safety, resulting in prolonged surgery time and increased complications, especially for beginners and elderly patients, which are often punctured and prone to joint prolapses. Bone destruction and hematoma.

Method used

Designed is a puncture needle assembly that adds multiple independent lumens by changing the outer cannula structure, including a needle core, a first cannula and a second cannula, the needle core can slide in the plurality of lumens and passes through a guide wire and scale to improve puncture accuracy.

Benefits of technology

It improves the accuracy of puncture, reduces the number of punctures and fluoroscopy, shortens the operation time, reduces the risk of surgical complications, and significantly improves the success rate of surgery.

Abstract

The puncture needle assembly comprises a needle core fixing cap, a needle core, a first outer sleeve handle, a first outer sleeve peripheral inner cavity, a first outer sleeve, a first outer sleeve center inner cavity, a first outer sleeve tail end opening, a second outer sleeve handle, a second outer sleeve inner cavity, a second outer sleeve and a guide wire. Five independently distributed circular hollow body structures are arranged in the first outer sleeve, the second outer sleeve is an independent inner cavity, and the needle core can be matched with the inner cavities of the first outer sleeve and the second outer sleeve. After puncture positioning is accurate through the first outer sleeve, the second outer sleeve is inserted into the vertebral body through conversion of the guide wire. The single inner cavity structure of the first outer sleeve is changed, and the same inner cavities are added in four directions, so that the puncture accuracy is improved, the puncture success rate is greatly increased, the puncture and perspective times are reduced, the operation time is shortened, and meanwhile, the operative complications are also reduced.
