AI Technical Summary

Technical Problem

Existing brain puncture trocars lack auxiliary positioning and adjustment structures, which leads to inaccurate puncture process, increases the risk of bleeding and brain tissue damage, and cannot effectively cooperate with ultrasonic detection equipment.

Method used

A brain puncture trocar was designed, which includes a spliced ​​telescopic dynamic separation mechanism and an extension control adjustment mechanism. Through the combination of hydrophobic scale stripes, micron ultrasonic reflection patterns, optical fiber filaments and laser ranging sensors, it can achieve real-time monitoring and precise positioning, and improve convenience and safety through a multi-layer nested structure.

Benefits of technology

It improves the convenience and accuracy of brain puncture trocar operation, reduces the risk of bleeding and brain tissue damage, adapts to the operating habits of different medical staff, and enhances the safety and stability of use.

Abstract

The invention discloses a brain puncture trocar for puncture of neonatal hydrocephalus through a fonfonis ventricle under ultrasonic guidance, and relates to the technical field of brain puncture trocar, the brain puncture trocar comprises a connecting seat main body, one end of the connecting seat main body is provided with a long round splicing piece, one side of the long round splicing piece is connected with a connecting hard cannula, and the other side of the long round splicing piece is connected with a connecting sleeve. The brain puncture trocar comprises a hard puncture needle and a connecting hard cannula, a liquid guide soft cannula is installed in the connecting hard cannula, and hydrophobic scale stripes are sprayed to the outer side of the liquid guide soft cannula, and it is ensured that the position of the hard puncture needle can be monitored in real time through an ultrasonic device in the puncture process of the brain puncture trocar; meanwhile, the position of the hard puncture needle is subjected to naked eye tracking through light spots formed by the optical fiber of the hard puncture needle under the skin of a patient, so that the depth and position monitoring mode in the puncture process of the brain puncture trocar is effectively expanded, and it is ensured that medical staff can clearly judge the puncture depth and position of the head of the brain puncture trocar in real time; therefore, the operation convenience and the operation precision of the whole brain puncture trocar are effectively improved.
