Microscopic direct vision system used for bone tissue aspiration biopsy

Abstract

The invention provides a microscopic direct vision system used for bone tissue aspiration biopsy, and belongs to the technical field of medical apparatus and instruments. The system mainly comprises amain shaft, a limiter, a mechanical arm, a clamping head, a puncture needle, a three-phase joint, a negative-pressure collector, a fiberscope, an adapter scope and an electron ocular. An arc-shaped gap is used as a window by using the fiberscope in the puncture needle, then the adapter scope is connected with the electronic ocular to serve as a camera shooting end, and images of the inside of pathological tissue are amplified through the electronic ocular and then transmitted to a computer, so that convenience is brought to visualized puncture and pathological tissue structure observation ofmedical workers. Besides, needle insertion is mechanically conducted, and compared with manual operation, the intensity of mechanical needle insertion is more uniform, and shaking is prevented. In a word, the system is reasonable in design, and has the advantages of being high in controllability, high in precision, high in diagnosis accuracy, high in safety and the like.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a microscopic direct vision system for bone tissue biopsy. Background technique [0002] In medical diagnosis, although there are various auxiliary examinations, pathological diagnosis is the most authoritative and can provide accurate clinical diagnosis, because it is more intuitive and objective. Medical disputes and legal disputes in clinical work often can only draw more correct conclusions through pathological diagnosis, so pathological diagnosis is also the final declarative diagnosis. Active tissue examination is referred to as biopsy, that is, using local cutting, forceps, fine needle aspiration, scraping and extraction, etc. to obtain lesion tissue from the living body of the patient for pathological examination. The significance of biopsy is that the lesion can be basically preserved due to the fresh tissue It is helpful to timely and accurately mak...

[0003] At present, the puncture operation at home and abroad is based on hand feeling to judge whether it is successful or not. These methods are blind and time-consuming. Even if the needle core reaches the pathological position by means of CT or B-ultrasound imaging, the puncture process is still based on Experienced manual operation, especially for some novices, often cannot grasp the
