[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] The utility model provides Figure 1-3 A fiberoptic bronchoscope introduction tube shown in the figure includes an introduction tube 1, a sealing top 2 is provided on one side of the introduction tube 1, an oxygen connection assembly is provided on the bottom of the sealing top 2, a sealing assembly is provided in the middle of the sealing top 2, the sealing assembly includes a rubber ring 3 inserted and connected in the middle of the sealing top 2, the cross-section of the rubber ring 3 is set to be semicircular, a pressing piece for strengthening the connection between the sealing top 2 and the rubber ring 3 is provided on one side of the sealing top 2, the reinforcing piece includes a connecting ring 4 provided on one side of the sealing top 2, the connecting ring 4 is sleeved in the middle of the rubber ring 3, and a pressing piece is provided on one side of the connecting ring 4.

[0018] It should be noted that a sealing hole adapted to the rubber ring 3 is provided in the middle of the sealing top 2. When in use, the rubber ring 3 is first inserted and fixedly connected in the sealing hole. The rubber ring 3 is made of rubber material, and the rubber material has a deformable property. When the rubber ring 3 is squeezed, it will deform. Therefore, when the bronchoscope needs to pass through the sealing top 2, the bronchoscope passes through the rubber ring 3, and the rubber ring 3 is squeezed by the bronchoscope, and the rubber ring 3 is deformed. The gap at the connection between the rubber ring 3 and the bronchoscope is filled by the deformed rubber ring 3, thereby preventing gas from overflowing from the connection between the bronchoscope and the rubber ring 3; the connecting ring 4 is fixed The fixed sleeve is arranged in the middle of the rubber ring 3, and the cross section of the connecting ring 4 is a circular ring, and the outer diameter of the circular ring is larger than the diameter of the sealing hole, so that the connecting ring 4 arranged on one side of the sealing top 2 cannot pass through the connecting hole to reach the inside of the introduction tube 1, thereby preventing the rubber ring 3 fixedly connected to the connecting ring 4 from passing through the sealing hole to enter the inside of the introduction tube 1 through the restriction of the connecting ring 4, and further fixing the position of the rubber ring 3; the set pressing piece is used to limit the connecting ring 4 to one side of the sealing top 2; the rubber ring 3 with a semicircular cross section is used to guide the bronchoscope to the hole in the middle of the rubber ring 3 through the guidance of the arc edge.

[0019] Furthermore, when the bronchoscope needs to be inserted into the introduction tube 1, the bronchoscope is guided to the middle of the rubber ring 3 through the curved surface of the rubber ring 3, and passes through the rubber ring 3 to reach the inside of the introduction tube 1. When in use, the gap at the connection between the rubber ring 3 and the bronchoscope is filled and sealed through the deformation of the rubber ring 3 made of rubber material. When the bronchoscope is inserted into the introduction tube 1, the rubber ring 3 is restricted by the connecting ring 4 to prevent the rubber ring 3 from being pushed into the introduction tube 1.

The position of the connecting ring 4 is fixed by the pressing block 7 in a fixed position to avoid the connection ring 4 fixedly connected to the rubber ring 3 being blocked by the pressing block 7 when the bronchoscope is pulled out and the rubber ring 3 is moved to the side away from the introduction tube 1, so that it cannot move.

[0022] Specifically, a through hole 8 is opened on the other side of the pressing block 7 , and the rubber ring 3 is inserted and connected inside the through hole 8 .

[0023] Specifically, a limiting rod 5 is centrally and symmetrically fixedly connected to one side of the sealing top 2 , a positioning hole 6 adapted to the limiting rod 5 is centrally and symmetrically opened in the middle of the connecting ring 4 , and the limiting rod 5 is inserted and connected inside the positioning hole 6 .

[0024] Specifically, a fixing hole 10 adapted to the limiting rod 5 is symmetrically opened on the inner wall of one side of the installation groove 9 , the fixing hole 10 and the positioning hole 6 are interconnected, and the limiting rod 5 is inserted and connected inside the fixing hole 10 .

[0025] It should be noted that at least four limit rods 5 are provided, and the plurality of limit rods 5 respectively pass through the connecting ring 4 with positioning holes 6, so that the connecting ring 4 is restricted at multiple locations and cannot rotate, and the rotation of the rubber ring 3 is restricted by restricting the rotation of the connecting ring 4.
