Bone tissue needle biopsy needle combination

Abstract

The invention discloses a bone tissue needle biopsy needle combination which comprises a locating sleeve and a through needle. The locating sleeve is provided with a gripping handle which is provided with a locating arm capable of replicating. A puncture sampling needle is matched in the locating sleeve in a gap mode. The puncture sampling needle comprises a needle rod and a handle which is provided with a locating groove corresponding to the locating arm. A cone-shaped needle head is arranged at the front end of the needle rod and is solid. A sampling hole is formed in the cone-shaped needle head. A cutting edge is arranged on the hole opening of the sampling hole. The sampling hole is communicated with a center hole of the needle rod. The inner diameter of the needle rod is smaller than 1/3 of the outer diameter of the needle rod. The needle rod is longer than an outer sleeve needle tube. The through needle is matched in the center hole of the needle rod in a gap mode. The through needle is longer than the needle rod. The puncture sampling needle is used as a supporting piece of puncture and can be used for sampling at the same time, so that operation steps are simplified, viable tissue is quickly taken, needle biopsy efficiency is improved, structure is simple, the viable tissue can be prevented from falling off from the biopsy cone-shaped needle head, and biopsy success rate is high.

AI Technical Summary

Benefits of technology

This invention relates to an improvement over existing puncturing devices that use pointed structures or blades like knives but they have limitations such as causing damage during insertion due to their shape. These improvements include better control at different angles while still being effective against soft tissues without damaging them. Additionally, these new designs simplify manufacturability and reduce costs associated with current methods.

Problems solved by technology

This technical problem addressed in this patents relates to improving the accuracy and efficiency of biopathology procedures performed at home without causing any negative side effects like unnecessary pain and damage caused by current techniques involving invasively accessing the target area. Current solutions involve collecting samples from patients' skin, extracting them, analyzing them manually, and reconstructing their shape before drawing back onto the subject. These processes require significant effort and may result in errors leading to poor quality data analysis and potential recurrence of tumours.
