[0043] An auxiliary component is provided on the hose 102, and the auxiliary component includes an auxiliary ring plate 108 and an auxiliary ring plate 2 109. An auxiliary display plate 2 121 is rotatably installed on the auxiliary ring plate 108, and an auxiliary bending seat 2 122 is fixedly installed on the auxiliary display plate 2 121. An auxiliary rotating plate 118 is rotatably installed on the auxiliary ring plate 2 109, and an auxiliary bending seat 117 is fixedly installed on the auxiliary rotating plate 118. A guide rod 119 is symmetrically fixedly provided on the auxiliary bending seat 117. When the guide rod 119 is engaged with the auxiliary bending seat 2 122 and the bending rotating seat 125, it is a sliding fit. Four elastic rods 116 are fixedly installed on the auxiliary ring plate 108 and the auxiliary ring plate 2 109. The elastic rod 116 on the auxiliary ring plate 108 slides with the fixed ring plate 107, and the elastic rod 116 on the auxiliary ring plate 2 109 slides with the auxiliary ring plate 108.

[0044] The bending swivel seat 125 is symmetrically fixed with air bags 127, and two auxiliary air tubes 3 126 are fixed on the air bags 127. Four auxiliary air tubes 2 123 are fixed on the auxiliary bending seat 2 122, and four auxiliary air tubes 1 120 are fixed on the auxiliary bending seat 1 117.

When the auxiliary ring plate 108 and the auxiliary ring plate 2 109 move following the bending swivel seat 125, the elastic rod 116 on the auxiliary ring plate 108 slides relative to the fixed ring plate 107, and the elastic rod 116 on the auxiliary ring plate 108 bends following the movement of the auxiliary ring plate 108.

[0045] In the initial state, when the adjustment seat 124 is driven to rotate, under the action of the guide rod 119, the auxiliary bending seat 117 and the auxiliary bending seat 2 122 rotate synchronously with the bending seat 125, that is, the auxiliary rotating plate 118 rotates on the auxiliary ring plate 2 109, and the auxiliary expansion plate 2 121 rotates on the auxiliary ring plate 1 108, thereby completing the adjustment of the bending direction of the lower end of the hose 102.

[0046] By introducing gas into the airbag 127, and then passing through the auxiliary trachea three 126, the auxiliary trachea two 123, and the auxiliary trachea one 120, the auxiliary trachea one 120 slides relative to the auxiliary trachea two 123, and the auxiliary trachea two 123 slides relative to the auxiliary trachea three 126, so that the guide rod 119 is separated from the contact with the auxiliary bending seat two 122 and the bending rotation seat 125, and the auxiliary ring plate two 109 slides relative to the auxiliary ring plate one 108, and the auxiliary ring plate one 108 slides relative to the fixed ring plate 107, so that the auxiliary bending seat one 117, the auxiliary bending seat two 122, and the bending rotation seat 125 are unfolded when the laryngoscope is inserted into the body, avoiding forming a large obstacle and causing strong discomfort to the patient.

[0047] The hose 102 is provided with auxiliary components, and the pneumatic components include a positioning air pipe 112, an extension air pipe 113, and a bending air pipe 114 fixedly connected to the hose 102. A fixed groove plate 135 and a fixed groove plate 2 136 are fixedly installed on the fixed ring plate 107. The fixed groove plate 135 and the fixed groove plate 2 136 form a closed chamber with the fixed ring plate 107. The positioning ring plate 137, the positioning cover plate 138, the positioning fixed ring plate 139, the positioning The strip plate 141 and the second fixed strip plate 142 form a closed chamber, the positioning air pipe 112 and the closed chamber formed by the positioning ring plate 137, the positioning cover plate 138, the positioning fixed ring plate 139, the positioning strip plate 141, and the second fixed strip plate 142 are connected, the extension air pipe 113 and the closed chamber formed by the second fixed groove plate 136 and the fixed ring plate 107 are connected, and the bending air pipe 114 and the closed chamber formed by the fixed groove plate 135 and the fixed ring plate 107 are connected.

[0048] An air supply pipe 2 129 and two air supply pipes 1 128 are fixedly installed on the adjustment and rotation seat 124.

A control motor 111 is fixedly installed on the side of the five-way valve 115, and the control motor 111 and the valve core of the five-way valve 115 are fixedly connected.

[0050] Gas is injected into the five-way valve 115 through the air pump 105, and the driving control motor 111 drives the valve core of the five-way valve 115 to rotate, so that the valve core of the five-way valve 115 rotates to the position corresponding to each air pipe, thereby realizing the injection of gas into the adjustment air pipe 112, the extension air pipe 113, and the bending air pipe 114.

[0051] Working principle: When inserted into the human body, the air pump 105 is started, and the five-way valve 115, under the control of the control motor 111, introduces gas into the adjusting trachea 112, the stretching trachea 113, and the bending trachea 114 respectively, so that the adjusting swivel seat 124 and the bending swivel seat 125 are in the initial state, that is, the adjusting swivel seat 124 is in the position where the adjusting strip 141 contacts the limiting short column 2 140 closest to the fixed strip 2 142, and the bending swivel seat 125 is in the position where the bending strip 132 contacts the limiting short column 1 133 closest to the adjusting swivel seat 124, and the auxiliary bending seat 1 117, the auxiliary bending seat 2 122, and the bending swivel seat 125 are in the expanded state, so as to avoid the auxiliary bending seat 117, the auxiliary bending seat 2 122, and the bending swivel seat 125 constituting a large obstacle and causing strong discomfort to the patient.

[0052] When the insertion direction of the lens 103 needs to be adjusted, the gas in the airbag 127 is first extracted by stretching the air tube 113, so that the auxiliary air tube 1 120, the auxiliary air tube 2 123, and the auxiliary air tube 3 126 are folded, that is, the auxiliary bending seat 2 122 is in contact with the bending rotation seat 125, and the auxiliary bending seat 1 117 is in contact with the auxiliary bending seat 2 122, that is, the guide rod 119 is in a connected state with the auxiliary bending seat 2 122 and the bending rotation seat 125.

[0053] Then, air is ventilated into the closed chamber formed by the positioning ring plate 137, the positioning cover plate 138, the positioning fixed ring plate 139, the positioning strip plate 141, and the fixed strip plate 142 through the positioning air pipe 112, driving the positioning fixed ring plate 139 to rotate, that is, driving the positioning rotary seat 124 to rotate, thereby adjusting the bending direction of the lens 103. Then, air is ventilated into the closed chamber formed by the bending cover plate 130, the bending ring plate 131, the bending strip plate 132, the fixed strip plate 134, and the adjusting rotary plate 110 through the bending air pipe 114, driving the adjusting rotary plate 110 to rotate, and then driving the bending rotary seat 125 to rotate, that is, driving the lower end of the hose 102 to bend, and then, with the cooperation of the positioning rotary seat 124 and the bending rotary seat 125, the insertion direction of the lens 103 is adjusted.
