Intracranial puncture needle applied to medical naked eye 3D

Abstract

The intracranial puncture needle comprises a main needle body, a main needle stem is arranged on the main needle body, a needle hole is formed in one end of the main needle stem, a needle handle is arranged at the other end of the main needle stem, a movable part is arranged on a fixed part, a connecting pipe is arranged in the main needle body, a second inner cavity is formed in the connecting pipe, and a first inner cavity is formed in the second inner cavity. Scale marks are arranged on a main needle stem of the intracranial puncture needle, an operator can accurately conduct puncture depth conveniently, convenience is brought to an operation, a breaking needle body is placed in the main needle body, a breaking needle stem is arranged in the breaking needle body, a movable part is connected to the upper end of the breaking needle stem, and the breaking needle stem is arranged in the movable part. The movable block on the movable part is movably connected with the clamping sleeve in the plunger on the needle handle, the movable part is manually rotated to rotate the crushing needle stem, the needle tip is arranged at the bottom end of the crushing needle stem, the crushing part is arranged on the needle tip, and the crushing needle stem rotates to drive the crushing part to rotate to crush intracranial blood clots.

Description

technical field [0001] The invention relates to the technical field of medical intracranial puncture needles, in particular to an intracranial puncture needle applied to medical naked-eye 3D. Background technique [0002] Glasses-free 3D, in layman's terms: it allows users to see 3D images without wearing 3D glasses, and displays 3D graphics on the computer, that is, displaying 3D graphics on a plane, unlike the real three-dimensional space in the real world, which has real In the distance space, the computer only looks very similar to the real world, so the 3D graphics displayed on the computer are just as real to the eyes. The human eye has a characteristic that it is close to the big and the far is small, and it will form a three-dimensional effect. It can be applied in medicine, and the intracranial puncture needle is to insert the needle tube into the cranium to suck out the hemorrhage or other objects in the cranium. [0003] There are many methods and instruments for...

AI Technical Summary

Problems solved by technology

At present, methods and instruments with less damage are used, such as pistol drill to drill the cranium or cone hole with a cone, then puncture to the hematoma, wash and crush with a porous needle or grind with an electric brush, but the above methods and instruments, both There are advantages, but also disadvantages, such as large craniotomy injury, hemiplegia, aphasia and other sequelae after recovery.

The damage of drilling and taper holes is small, but the brush is easy to damage the blood vessels and cause hematoma to recur. Some larger blood clots are not easy to break during the traditional method of crushing the hematoma, and the drainage and flushing process requires multiple steps. , need a kind of intracranial puncture needle applied in medical naked-eye 3D to solve this problem
