Problems solved by technology

The diameter of the existing rigid bronchoscope is relatively thick and cannot be bent, so it cannot be inserted into the tertiary bronchi. When using a rigid bronchoscope with foreign body forceps to grasp the foreign body located in the tertiary bronchus, the foreign body can only be grasped by the surgeon's feeling. Difficult to achieve good surgical results
Existing flexible bronchoscopes are soft, flexible, and have a narrow channel, so they can be inserted into the third-level bronchus to capture foreign bodies located in the third-level bronchus, but cannot capture larger foreign bodies located in the second-level bronchus
When the surgeon uses a rigid bronchoscope with foreign body forceps to grasp a large foreign body in the second-level bronchus, the foreign body may slide down to the third-level bronchi under the action of external force during the process of grasping the foreign body. The bronchoscope was pulled out, and the flexible bronchoscope was reinserted for a second operation, which caused great harm to the patient's body

Embodiment 1

[0026] refer to Figure 1 ~ Figure 4 , the present embodiment provides a two-stage bronchoscope for tracheal foreign body surgery, comprising a tube mirror main body 10, a rigid mirror tube 20 and a flexible mirror tube 30, and the central part of the tube mirror main body 10 is provided with a central channel running through its top surface and bottom surface The side of the mirror tube main body is provided with an air intake channel 12 and an optical fiber channel 13 communicating with the central channel, the hard mirror tube 20 is fixedly connected to the bottom of the central channel, and the flexible mirror tube 30 is slidably sleeved in the hard mirror tube 20. The upper end of the mirror tube 30 protrudes from the mirror tube body 10 and is provided with an aspirator interface, and the lower end of the flexible mirror tube 30 can extend out of the hard mirror tube 20 to reach the third-stage trachea; the flexible mirror tube 30 includes an outer hose 31 and an inner ho...

Embodiment 2

[0036] A method of using the two-stage bronchoscope for tracheal foreign body surgery in Embodiment 1, the intake channel 12 is connected to an oxygen pump or a ventilator, and the illumination optical fiber 33 and the image transmission optical fiber 34 are respectively connected to the optical fiber lighting system and the optical fiber imaging system, By adjusting the light source control button, the brightness of the light source is adjusted, and the image of the foreign object collected by the optical fiber image transmission bundle 34 is clearly displayed on the display screen;

[0037] The operator holds the handle part 14 and inserts the hard mirror tube 20 with the flexible mirror tube 30 into the bronchus of the human body, and checks the position of the foreign body by observing the display screen. ; in the process of clamping the foreign matter, once the foreign matter falls to the third-stage trachea by the external force, the turning wheel 53 drives the driving ge...

Embodiment 3

[0039] A method of using the two-stage bronchoscope for tracheal foreign body surgery in Embodiment 1, the intake channel 12 is connected to the oxygen pump, the illumination optical fiber 33 and the image transmission optical fiber 34 are connected to the optical fiber lighting system and the optical fiber imaging system respectively, and the light source is adjusted to The control button adjusts the brightness of the light source, and makes the image of the foreign object collected by the optical fiber image transmission bundle 34 clearly displayed on the display screen;

[0040] The operator holds the handle part 14 and inserts the hard mirror tube 20 with the soft mirror tube 30 into the bronchus of the human body, and checks the position and type of the foreign body by observing the display screen. The interface of the suction device is connected to the suction device, and the dial 53 is turned to drive the lower end of the flexible mirror tube 30 to protrude from the bott...

Abstract

The invention discloses a using method of a two-stage bronchoscope for a tracheal foreign body operation. The use method comprises a method for sucking small and fragile foreign bodies through negative pressure, a method for taking metal foreign bodies through magnetic adsorption and a method for clamping common foreign bodies through foreign body forceps. A soft bronchoscope tube is sleeved with a hard bronchoscope tube, the tube wall of the soft bronchoscope tube can be made to be thin, a foreign matter channel in the soft bronchoscope tube is large, and the two-stage bronchoscope is matched with a pair of foreign matter forceps, so that hard objects at a second-stage bronchus and a third-stage bronchus can be easily clamped; and moreover, when a hard object at a second-stage bronchus is clamped, once a foreign matter slides down to a third-stage bronchus, the lower end of the flexible lens tube can extend out to reach the third-stage bronchus, a good surgical effect can be achieved by matching with foreign matter forceps, and injury to the body of a patient caused by a second operation can be avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a method for using a two-stage bronchoscope for trachea foreign body surgery. Background technique [0002] Existing tracheal foreign body surgery uses rigid bronchoscope with foreign body forceps, or flexible bronchoscope with foreign body forceps. The trachea is dilated through rigid bronchoscope or soft bronchoscope, and the surgeon uses foreign body forceps to remove the foreign body through the foreign body channel of the bronchoscope. The foreign body is removed. The diameter of the existing rigid bronchoscope is relatively thick and cannot be bent, so it cannot be inserted into the tertiary bronchi. When using a rigid bronchoscope with foreign body forceps to grasp the foreign body located in the tertiary bronchus, the foreign body can only be grasped by the surgeon's feeling. Difficult to achieve good surgical results. The texture of existing flexible bronchosco...
