Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a visual occluder that is easy to locate. Background Technology

[0002] Existing visual occluders on the market are generally divided into two types: one relies on a camera at the front of the cuff to determine the insertion point, and the other relies on a camera at the rear of the cuff to determine whether the insertion is in place. Both types inevitably have some drawbacks. The first type allows for easy observation of the lateral bronchus to be occluded and quick location of the insertion point, but because the camera is at the front of the cuff, the cuff itself cannot be observed, making it impossible to determine whether the occlusion is accurate and in place. The second type has the camera at the rear of the cuff, which can determine whether the occlusion is accurate and in place, but because the camera is at the rear of the cuff, the cuff inevitably affects the camera's field of view, making it difficult to clearly observe the position of the lateral bronchus. This application addresses these shortcomings. Utility Model Content

[0003] The purpose of this invention is to provide a visual blocking device that is easy to locate. By using two cameras, front and rear, it combines the advantages of the two types of visual blocking devices mentioned above and solves the problems of traditional single-camera visual blocking devices.

[0004] To address the aforementioned problems, this utility model provides a visual occlusion device for easy positioning, comprising a bronchial tube, a cuff, a front-end camera, and a rear-end camera. The cuff is mounted on the bronchial tube. The front-end camera and the rear-end camera are respectively positioned at the front (distal) and rear (proximal) ends of the cuff. The bronchial tube is connected to a flushing port, and a flushing chamber connected to the flushing port is provided within the bronchial tube. A flushing port connected to the flushing chamber is provided on the bronchial tube, through which liquid sprayed can flush the rear-end camera. The bronchial tube is provided with a bending structure and a bending section. The bending structure is used to adjust the bending of the bending section, which is positioned between the rear-end camera and the cuff.

[0005] The front-end camera ensures that the occluder tip enters the lateral bronchus that needs to be blocked. Then, the insertion depth is adjusted through the field of view of the rear-end camera, and the angle of the cuff is adjusted through the bending structure and the curved section, so that the cuff is accurately and properly delivered into the lateral bronchus that needs to be blocked.

[0006] During the surgery, the continuous stimulation of the cuff on the patient can cause sputum to be secreted in the airway, obstructing the camera's field of view. At this time, saline solution can be injected through the flushing port, and the saline solution can be sprayed out through the flushing port to flush the surface of the rear camera, ensuring stable imaging.

[0007] According to one embodiment of the present invention, the bending structure includes a wire and an adjusting handle. One end of the wire is connected to the bending structure section, and the other end is connected to the adjusting handle. The adjusting handle is used to adjust the length of the wire.

The rotating shaft is installed in the shaft cavity, and the length of the thread is controlled by rotating the rotating shaft.

[0009] According to one embodiment of the present invention, a self-locking ejection device is provided on the rotating shaft. The self-locking ejection device has a structure similar to a spring ball, including a spring and a probe. The universal buckle is provided with several slots that cooperate with the self-locking ejection device. The probe extends into the slot to achieve a position locking effect.

[0010] According to one embodiment of the present invention, at least two sets of the silk threads are provided, the number of fixing holes is the same as the number of silk threads, the fixing holes are through holes, and the two silk threads are fixed on the left and right sides respectively.

[0011] According to one embodiment of the present invention, the universal buckle is assembled from two parts, which are connected by buckles to facilitate installation.

[0012] According to one embodiment of the present invention, a handle is installed on the rotating shaft, and the rotation of the rotating shaft is controlled by the handle.

[0013] According to one embodiment of the present invention, the bronchial tube is connected to a spraying interface, the bronchial tube is provided with a spraying chamber connected to the spraying interface, and the bronchial tube is provided with a spraying nozzle connected to the spraying chamber. The spraying direction of the spraying nozzle should be away from the camera to avoid drug residue on the camera.

[0014] According to one embodiment of the present invention, the bronchial tube is equipped with a pre-inflation device and an indicator cuff connected to the cuff, which are used to inflate the cuff and indicate the cuff pressure, respectively. The bronchial tube is also equipped with a conversion connector for the insertion of instruments.

[0015] According to one embodiment of the present invention, both the front-end camera and the rear-end camera are connected to a camera adapter cable, which extends from the proximal end (operating end) of the bronchial tube.

[0016] According to one embodiment of the present invention, both the front-end camera and the rear-end camera include an imaging component and an LED lighting component to ensure clear imaging.

[0017] The beneficial effects of this utility model are as follows: In this solution, cameras are set at both the front and rear ends of the cuff. During the occlusion operation, the front camera ensures that the front end of the occluder enters the lateral bronchus that needs to be blocked. The insertion depth is adjusted by the field of view of the rear camera, and the angle of the cuff is adjusted in conjunction with the bending structure and the bending section, so that the cuff is accurately and properly delivered into the lateral bronchus that needs to be blocked.
