Lung tissue extraction device based on medical examination

Abstract

The invention discloses a lung tissue extraction device based on medical examination, relates to the technical field of lung sampling, and solves the problems that in the existing lung tissue extraction process, the sampling amount is small, the operation is troublesome, and the working efficiency of examination is influenced. The device comprises an outer shell; an operation button which is mounted at the upper part of the outer shell in a sliding manner; a cutting-off driving mechanism which is located in the outer shell; an extraction needle main body, which is of a needle-shaped structure, and is fixedly connected to the right side of the outer shell. Focus tissue entering the sampling opening is adsorbed and fixed, the sampling amount is guaranteed, detection failure caused by too small sampling amount is effectively prevented, repeated sampling is avoided, meanwhile, the miniature vacuum pump is started while the cutting needle slides leftwards, opening and closing of the miniature vacuum pump do not need to be controlled additionally, operation is reduced, use is convenient, and the working efficiency is improved; the pain of the patient is reduced, and the interference to the illness state is smaller.

Description

technical field [0001] The invention relates to the technical field of lung sampling, in particular to a lung tissue extraction device for medical testing. Background technique [0002] In the Department of Respiratory Medicine, the health of the lungs is generally checked by means of radiographic imaging, but in the process of diagnosis of tuberculosis or malignant tumors, the tissue at the lesion is usually extracted by biopsy to ensure accurate diagnosis. To facilitate the formulation of the next treatment plan. [0003] For example, application number: CN201920625006.6 The utility model discloses an auxiliary trocar for multiple lung biopsy used in conjunction with a semi-automatic biopsy gun, which consists of a tube sheath (4) and a needle core (5), the tube sheath (4) The inner diameter and length are matched with the tip (2) of the semi-automatic biopsy gun, and the needle core (5) is put through the tube sheath (4). This auxiliary trocar for multiple lung biopsy c...

Problems solved by technology

[0005] The purpose of the present invention is to provide a lung tissue extraction device based on medical testing to solve the problem that the existing lung tissue extraction process proposed in the above background technology tends to have a small sampling volume, which is difficult to meet the needs of the laboratory and needs to be repeated. The tissue extraction work increases the pain of the patient, multiple sampling has a greater impact on the development of the disease, the operation is troublesome, and the problem of affecting the work efficiency of the inspection
