Description

Technical Field

[0001] This invention relates to a bronchoscope accessory, and more specifically, to an accessory that provides a backup access for a bronchoscope. Background Technology

[0002] Current bronchoscopy devices are used to observe and examine the trachea by inserting a tube into the trachea and relying solely on the end lens. Therefore, during use, it is often necessary to operate other equipment to complete medical procedures such as examinations and treatments. During interventional procedures, the bronchoscope lens is easily blurred by secretions in the trachea. Whether the lens is withdrawn for cleaning or other equipment is inserted into the trachea for processing, a significant amount of time is required for adjustment and coordination. This not only leads to inefficiency but also increases the risk of secondary injuries such as wound infection. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an accessory that provides a backup channel for a bronchoscope, which can keep the lens clear.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an accessory for providing a backup channel for a bronchoscope, comprising a sleeve for being fitted onto a bronchoscope, the sleeve being connected to a fixing head for fixing onto the bronchoscope and an auxiliary channel disposed on the sleeve, the auxiliary channel being detachably connected to a channel tube, and the channel tube being connected to a connector for connecting to an external device.

[0005] In summary, the present invention has the following beneficial effects: During operation, the cannula is placed on the inlet tube of the bronchoscope and fixed to the bronchoscope with the fixing head. The connector is connected to the external device. The channel tube can also be used for injecting medication or negative pressure suction. The side channel auxiliary channel is established. By using negative pressure suction or injecting saline, the lens can be kept clear, which makes it easier for doctors to perform more precise operations and treatments.

[0006] The channel tube and connector are detachable. When other accessories are needed, the connector can be removed and the accessories can be inserted through the channel tube. Alternatively, the channel tube can be removed and inserted into the air tube for internal operation. The accessories can also be moved with the lens for coordinated operation, thereby reducing adjustments and improving efficiency. Attached Figure Description
