Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, in particular to a bronchoscope with a visual balloon. Background Art

[0002] Currently, bronchoscopy is widely used in the diagnosis and treatment of clinical patients, including common bronchoscopic lavage, biopsy, and balloon dilatation of stenotic airways. Lavage and biopsy can easily cause bronchial bleeding. When bleeding or bleeding is excessive, it can easily lead to life-threatening complications such as airway obstruction and asphyxiation. Timely hemostasis and occlusion of relevant lung branches are necessary to maintain airway patency. Airway stenosis often causes respiratory obstruction in patients, leading to various respiratory complications and even life-threatening conditions. Timely balloon dilatation is required to maintain airway structure and dilate the airway.

[0003] To address these issues and reduce medical risks, existing technologies have begun to incorporate safety balloons on the outer periphery of the front end of some bronchoscopes. When bleeding occurs due to lavage or biopsy, the safety balloon is inflated to compress the bleeding point. However, the bronchoscope's camera, originally intended to observe the direction of travel and provide a field of view for surgical operations in front of the bronchoscope, must be located directly at the front end of the bronchoscope. This results in the safety balloon not being able to compress the bleeding point when it is visible, and the camera cannot see the bleeding point when the safety balloon is inflated. Therefore, preventive or therapeutic deployment of the safety balloon to compress bleeding and block lung branches cannot be achieved using the bronchoscope's built-in camera. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a bronchoscope with a visual balloon, which provides a second visual field for the balloon and accurately guides the inflation of the balloon to compress and dilate the trachea.

[0005] The technical solution adopted by the utility model to solve its technical problems is: to provide a bronchoscope with a visual balloon, including a connected handle and an entry tube, a working channel is provided in the center of the entry tube, an inflatable airbag is provided on the outer periphery of one end of the entry tube away from the handle, and a second camera is provided on the side surface of the entry tube for confirming the position of the airbag.

[0006] Preferably, a first camera is provided at the front end of the in-body tube.

[0007] Preferably, the material of the airbag is transparent, and the second camera is arranged on a side of the airbag away from the first camera.

[0008] Preferably, the second camera is arranged on a side outside the airbag away from the first camera.

[0009] Preferably, a first video connection connected to the first camera, a second video connection connected to the second camera, and an inflation channel connected to the airbag are provided in the tube wall of the in-body tube.

[0010] Beneficial effects

[0011] The utility model provides a second camera inside or behind the airbag to confirm the position of the airbag. When bleeding occurs during surgery, the second camera can be used to promptly confirm that the airbag has reached the bleeding point, accurately inflate and compress the bleeding point, and avoid life-threatening complications such as airway obstruction and suffocation caused by excessive bleeding. When airway stenosis requires expansion, a visual balloon can be used to accurately expand the narrowed airway. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that such equivalents also fall within the scope of the claims appended hereto.

[0017] like Figure 1 As shown, the utility model provides a bronchoscope with a visual balloon, comprising a connected handle 1 and an entry tube 2, wherein a working channel 204 is provided at the center of the entry tube 2, an inflatable airbag 5 is provided on the periphery of one end of the entry tube 2 away from the handle 1, and a second camera 4 is provided on the side surface of the entry tube 2 for confirming the position of the airbag 5.

[0018] In one specific embodiment, the front end of the in-body tube 2 is provided with a first camera 3. Surrounding the working channel 204 and within the wall of the in-body tube 2 are provided a first video cable 201 connected to the first camera 3, a second video cable 202 connected to the second camera 4, and an inflation channel 203 connected to the airbag 5. The first video cable 201 is terminated with a first video connector 601, the second video cable 202 is terminated with a second video connector 602, and the inflation channel 203 is terminated with an inflation connector 604.

[0019] The first video connector 601, the second video connector 602, the inflation connector 604 and the working connector 603 at the end of the working channel 204 pass through an outlet opened on the connecting pipe section 6 between the handle 1 and the in-body tube 2. The first video connector 601 and the second video connector 602 are connected to an external display screen, and the inflation connector 604 is connected to the inflation equipment.

[0020] like Figure 2 As shown, in a specific embodiment, the material of the airbag 5 is transparent, and the second camera 4 is arranged on a side of the airbag 5 away from the first camera 3, so it is called a visual airbag 5.

[0021] In another embodiment, the second camera 4 is disposed outside the airbag 5 and away from the first camera 3 , and observes the position of the airbag 5 from the rear side of the airbag 5 to the front.

[0022] The first and second cameras 3 and 4 are fisheye cameras, providing a wider field of view in confined spaces. Even if the bleeding point is on the opposite side of the second camera 4, the second camera 4 can still detect bleeding in front of the patient. Due to the long length of the airbag 5, only one second camera 4 is generally required. In other embodiments, a third camera or more cameras can be positioned opposite the second camera 4 to provide a more comprehensive field of view.

[0023] During use, supported by images captured by the first camera 3, other surgical instruments can be inserted into the working channel 204 via the working connector 603 and exit through the opening at the end of the access tube 2 to perform bronchoscopic-assisted surgery. If a bleeding point is present during invasive surgery, the access tube 2 can be pushed forward via the handle 1 after the procedure is complete or in an emergency. Once the second camera 4 confirms that the airbag 5 has reached the bleeding point, the airbag 5 is inflated via the inflation channel 203 to achieve compression and hemostasis.
