Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of endoscopes, in particular to an endoscope auxiliary catheter and an endoscope device. Background Art
[0002] The fiber bronchoscope, abbreviated as fibrobronchoscope, is applicable to the observation of lesions in the lung lobes, segments and sub-segments, biopsy sampling, bacteriological and cytological examinations, and can be used for photography, teaching and dynamic recording in cooperation with a TV system. This bronchoscope is attached with a biopsy sampling structure, which can help detect early lesions, and can perform in-vivo surgical operations such as polyp removal. It is an excellent precision instrument for the research of bronchial and lung diseases and postoperative examinations.
[0003] In clinical practice, many patients have a large amount of sputum secreted in the respiratory tract due to long-term smoking and inflammatory stimulation. The sputum easily adheres to the head end of the fibrobronchoscope, blocking the operator's vision. The presence of sputum seriously affects the operator's judgment of the local structure, prolongs the intubation time, and greatly reduces the success rate of fibrobronchoscope intubation. Therefore, it is necessary to design an endoscope auxiliary catheter that can avoid the influence of airway secretions on endoscope intubation. Summary of the Utility Model
[0004] In view of the above problems in the prior art, the present application proposes an endoscope auxiliary catheter and an endoscope device that can avoid the influence of airway secretions on endoscope intubation.
[0005] One aspect of the utility model provides an endoscope auxiliary catheter. The endoscope auxiliary catheter includes a flexible catheter body. A partition plate is arranged inside the flexible catheter body, and the partition plate divides the flexible catheter body into a flushing channel and a suction channel. A flushing joint communicated with the flushing channel is arranged on the flexible catheter body, and a suction joint communicated with the suction channel is arranged on the flexible catheter body. The flexible catheter body can follow the endoscope for intubation. The flushing joint can be communicated with a flushing device so that the flushing device flushes airway secretions through the flushing channel, and the suction joint can be communicated with a suction device so that the suction device sucks airway secretions through the suction channel.
[0006] As a further improvement of the above technical solution:
[0007] For the above endoscope auxiliary catheter, further, a connection joint communicated with the flushing channel is arranged on the flexible catheter body, and the probe of the endoscope can pass through the connection joint, pass through the flushing channel and extend out.
[0008] Another aspect of the utility model provides an endoscope device, which includes an endoscope and the endoscope auxiliary catheter as described above.
[0009] For the above visual mirror device, further, the visual mirror is a fiber bronchoscope or a flexible visual electronic bronchoscope.
[0010] The above technical features can be combined in various suitable ways or replaced by equivalent technical features, as long as the purpose of the present utility model can be achieved.
[0011] Compared with the prior art, the visual mirror auxiliary catheter and the visual mirror device provided by the present utility model have at least the following beneficial effects: When visual mirror intubation is required, the visual mirror auxiliary catheter is inserted along with the visual mirror. During intubation, the flushing joint is connected to a flushing device so that the flushing device flushes the airway secretions through the flushing channel, and the suction joint is connected to a suction device so that the suction device sucks the airway secretions through the suction channel, thereby preventing the airway secretions from adhering to the head end of the visual mirror and blocking the operator's vision.
