Problems solved by technology
[0002] The bronchopulmonary lesions found clinically have the characteristics of variable location and shape, and when the existing fiberoptic bronchoscope brushes the bronchopulmonary lesions with a brush, the bristles of the brush are straight and located at the bottom of the brush rod. However, there are the following disadvantages: (1) It is not easy to brush the lesion or the tissue contained in the brushed tissue contains relatively few disease components, resulting in missed diagnosis; Excessive normal tissue damage leads to the reduction of the body's defense function, which easily leads to the occurrence of infection and the spread of lesions

Embodiment Construction
[0008] With reference to the accompanying drawings, the present invention includes a brush handle 1, a brush rod 2 and a bristle 3, and is characterized in that the brush rod 2 is provided with a bristle 3 on the arc surface 4 less than 180 degrees at the front of the brush rod 2, and on the brush rod 2 behind the two sides of the bristle 3 Airbags 5 are provided respectively, the inflation tubes 6 of the two airbags 5 are respectively arranged on both sides of the brush handle 2, and the inflation port 7 is arranged at the end of the brush handle. Said airbag end 8 is higher than the brush rod end 9 .
[0009] When in use, according to the characteristics of bronchopulmonary lesions, the two airbags 5 can be filled with gases of different contents, thereby adjusting the brushing direction and brushing surface, and protecting the surrounding normal tissues.

The invention relates to a bronchofiberscope balloon directional hair brush which comprises a brush holder (1), a brush bar (2) and a brushing (3), and is characterized in that the brushing (3) is arranged on a cambered surface (4) which is smaller than 180 degrees at the front part of the brush bar (2); two balloons are respectively arranged on the brush bar (2) opposite to the rear part of bothsides of the brushing (3); gas filled tubes (6) of the two balloons (5) are respectively arranged at both sides of the brush bar (2); an inflation inlet (7) is arranged at the end part of the brush holder (1), the end part of the balloon (8) is higher than the end part of the brush bar (9). The invention has simple structure and convenient operation, can improve the accuracy rate of brush examineof bronchopulmonary lesion, and reduces infection occurring and lesion diffusion.
Description
technical field [0001] The invention belongs to the technical field of medical devices, in particular to a fiber bronchoscope air bag directional brush. Background technique [0002] The bronchopulmonary lesions found clinically have the characteristics of variable location and shape, and when the existing fiberoptic bronchoscope brushes the bronchopulmonary lesions with a brush, the bristles of the brush are straight and located at the bottom of the brush rod. However, there are the following disadvantages: (1) It is not easy to brush the lesion or the tissue contained in the brushed tissue contains relatively few disease components, resulting in missed diagnosis; Excessive normal tissue damage leads to the reduction of the body's defense function, which easily leads to the occurrence of infection and the spread of lesions. Contents of the invention [0003] The purpose of the present invention is to address the above situation, to provide a fiberoptic bronchoscopic airb...
