the utility model discloses a concrete structure of fiberoptic bronchoscope intubate pipe with support function is shown in fig. 1 to 5, including pipe 1, set up bronchoscope direction passageway 2, first installation passageway 3 and second installation passageway 4 on the pipe 1, install the epiglottis bearing structure 5 that is used for supporting the epiglottis in the first installation passageway 3, install the tongue bearing structure 6 that is used for supporting the tongue in the second installation passageway 4. The first installation channel 3 is located above the bronchoscope guidance channel 2, and the second installation channel 4 is located below the bronchoscope guidance channel 2. Both the epiglottis support structure 5 and the tongue support structure 6 have a stowed state retracted to reduce the volume of the conduit and an extended state extended for supportive use.
The epiglottis support structure 5 comprises a first adjustment key 51, a winding wheel 52, a lever 53, an epiglottis support end 54, a wire rope 56 and a guide wheel 57. Wherein the upper end of the conduit 1 is provided with an avoiding groove communicated with the first installation channel 3, the main part of the first adjusting key 51 is arranged in the first installation channel 3, the epiglottis support end 54 is arranged at the tail end of the first adjusting key 51 through a hinge shaft extending along the width direction of the conduit 1, and the head end of the first adjusting key 51 is extended out of the avoiding groove to push the epiglottis support end 54 along the length direction of the conduit 1. The epiglottis support end 54 is made of silicone to alleviate patient discomfort. A guide pulley 57 is mounted on the side wall of the first mounting channel 3 remote from the epiglottis support end 54, a winding pulley 52 is rotatably mounted at the head end of the catheter 1, and a lever 53 is fixed to the winding pulley 52 to rotate the winding pulley 52. One end of the wire rope 56 is fixed to the epiglottis support end 54, and the other end is fixed to the head end of the catheter 1 after passing around the guide pulley 57 and the winding pulley 52 in order. After the first adjusting key 51 is pushed to drive the epiglottis support end 54 to extend to the lower part of the epiglottis, the deflector rod 53 is pulled to rotate the rope winding wheel 52 towards the rope winding direction, and the tail end of the epiglottis support end 54 can be driven to lift upwards, so that the function of picking up the epiglottis is achieved. The guide pulley 57 serves to prevent the cable 56 from being caught at the joint between the epiglottis support end 54 and the first adjustment key 52.
In this embodiment, the cable 56 is secured to the head end of the epiglottis support end 54 to prevent the cable 56 from contacting the patient's epiglottis. In other embodiments, the cable 56 may be secured to the trailing end of the epiglottis support end 54, but in such cases it may be desirable to provide the epiglottis support end 54 with a perforation extending lengthwise towards the leading end to prevent the cable 56 from contacting the patient's epiglottis.
In other embodiments, the guide wheel 67 could be omitted, but it would be necessary to rotate the winding wheel to wind the hanging wire when retracting the epiglottis support end 54 to avoid the wire getting caught at the juncture of the epiglottis support end 54 and the first adjustment key 52 when reextracting the epiglottis support end 54.
The tongue support structure 6 comprises a second adjustment key 61 and a tongue supporting end. The tongue supporting end is exposed out of the catheter 1 and comprises a hard part 62 and a soft part 63 covering the lower part of the hard part 62, the hard part 62 is fixed at the tail end of the second adjusting key 61, and the soft part 63 is made of silica gel.

The pipe wall of the guide pipe 1 is provided with a first limiting groove 11 and a second limiting groove 12 at intervals along the vertical direction, and the tops of the first limiting groove 11 and the second limiting groove 12 are communicated with the second mounting channel 4. The second adjusting key 61 includes a stopper 64, and the first and second limiting grooves 11 and 12 are adapted to the stopper 64 for being clamped in. When the second adjusting key 61 is located at the upper limit position, the second adjusting key and the first limiting groove 11 are located at the same height; the second adjustment key 61 is located at the same height as the second limit groove 12 when located at the lower limit position. When the tongue needs to be supported, the catheter 1 is placed at a proper position, the tongue supporting end is located above the position, away from the tongue root 1/3, of the patient, the second adjusting key 61 is pushed in the width direction of the catheter 1, the stop block 64 exits from the first limiting groove 11 and enters the second installation channel 4, the second adjusting key 61 is pulled downwards to the lower limit position, and the stop block 64 can be clamped in the second limiting groove 12 by pushing the second adjusting key 61 in the width direction of the catheter 1. The tongue supporting end supports the tongue by moving down the second adjusting key 61. The material of the hard portion 62 may be stainless steel, wood or plastic, and the hard portion 62 may be integrally formed with the second adjustment key 61, or may be fixed to the tail end of the second adjustment key 61 by welding or gluing. In other embodiments, a buckle may be further provided at the head end of the second adjustment key 61 for the operator to hold.
The tail end of pipe 1 is the step structure, and pipe 1's upper end is longer, supplies to set up bronchoscope guide channel 2, first installation passageway 3 and epiglottis support structure 5, and pipe 1's lower extreme is shorter in order to set up second installation passageway 4 and tongue support structure 6, and second adjustment key 61's latter half and tongue support end are stretched out by pipe 1's tail end. This ensures that the thickest part of the catheter 1 is located at the outer edge of the mouth and does not protrude deep into the mouth, causing discomfort to the patient. Meanwhile, when the epiglottis support structure 5 and the tongue support structure 6 are in the extending state, the epiglottis support end and the tongue support end are positioned at different axial length positions of the catheter 1, which is more in line with the human body structure, and can play a good role in supporting and fixing the epiglottis and the tongue at the same time.
In other embodiments, the soft portion may also be rubber, or the soft portion may be omitted directly; the tongue supporting structure can be replaced by an elastic sheet driven by a second adjusting key, the elastic sheet is fixed at the tail end of the second adjusting key to move back and forth along with the second adjusting key, the elastic sheet is made of spring steel and has a prestress which is popped downwards to generate deformation, when the tail end of the elastic sheet is pushed to extend out of the conduit, the elastic sheet pops downwards under the action of elastic force to play a role in supporting the tongue, and when the structure is used, the prestress on the elastic sheet needs to be accurately controlled or a damping device needs to be additionally arranged to control the popping amplitude and the force of the elastic sheet; and the second adjusting key is required to be completely arranged in the second mounting channel and cannot be exposed out of the guide pipe; the epiglottis support structure may take the same form as the tongue support structure, and the epiglottis support end is lifted by pulling the first adjustment key up and down to support the epiglottis.
