Visualized pleura brush cytology instrument

Abstract

The invention discloses a visualized pleura brush cytology instrument. The visualized pleura brush cytology instrument comprises a main body and an image acquisition mechanism, wherein the main body is in the shape of an L; a biopsy channel is formed in the main body; a displayer and a light source host machine are mounted at the top of the vertical part of the main body; a biopsy hole is formed in the side wall of the vertical part of the main body; and the image acquisition mechanism is located at the tail end of a horizontal part of the main body, and is electrically connected with the displayer and the light source host machine. According to the visualized pleura brush cytology instrument disclosed by the invention, the brush cytology device is firstly a visual device, so that the risks of blind brushing and blind test are avoided; through the L-shaped design, a cell brush is preferably jointed to the chest wall; besides, through the protecting effect of a brush cytology groove, the scouring action of hydrothorax to the cell brush is reduced, so that the brush cytology positive rate is increased, and the risk is reduced; and the visualized pleura brush cytology instrument has the advantage of being portable and small in damage, so that the visualized pleura brush cytology instrument is suitable for developing brush cytology at bedside and in an endoscope chamber.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a visual pleural brushing instrument. Background technique [0002] Pleural effusion is the most common manifestation of pleural diseases, and the diagnosis of pleural cavity etiology is the most important. Pleural effusion is divided into exudate and transudate in laboratory examination. The transudate usually has a definite primary disease, is non-malignant, and has a clear diagnosis; the etiology of the exudate is complex, and tuberculosis and lung cancer are more common, and it can also be seen in sarcoidosis, etc., but it is difficult to identify, so early diagnosis is very important clinically. The identification of the etiology of pleural effusion has always been a clinically important issue. In China, it is mainly the identification of tuberculous and malignant pleural effusion. In addition to the appearance of pleural effusion, routine, biochemical, bacteriologi...

AI Technical Summary

Problems solved by technology

In 2014, Rong Yan et al. analyzed and reported the reasons for the failure of pleural brushing operation: the current use of bronchoscope brushes is mainly due to the inability to fit closely with the pleura; the second is the erosion of the biopsy brush by a large amount of pleural effusion, resulting in the removal of cells Reduced; moreover, no adhesions and lesions can be seen during blind brushing, which leads to inability to moderate and switch movements, resulting in bleeding and brushing failure when brushing a large number of red blood cells. Important, pleural effusion is divided into exudate and transudate in laboratory exam
