[0026] Example 1
[0027] like Figure 1-Figure 4 As shown;
[0028] A dental pad and tracheal cannula integrated medical appliance comprises a cannula body.
[0029] The existing bite block and endotracheal tube are usually separately arranged, and a placement hole is opened inside the bite block. The patient bites the bite block in advance, and then the endotracheal tube is passed through the placement hole and inserted into the patient's trachea under observation through an endoscope.

[0045] In an optional embodiment: a positioning hole is opened on one side of the fixing box 4, and the side surface of the positioning shaft 14 fits with the inside of the positioning hole.
[0046] In this embodiment, the positioning shaft 14 is convenient for limiting the position of the fixing tube 13 .
[0047] The working principle and use process of the utility model are as follows: when the cannula body 1 needs to be used, the bidirectional threaded rod 5 is rotated to drive the two threaded seats 6 away from each other, thereby driving the two limit blocks 7 away from each other, thereby driving the two anti-skid pads 8 away from each other, so that the cannula body 1 loses its limit. At this time, the cannula body 1 can move in the tooth pad body 2, allowing the patient to bite the bite pad 3 on the tooth pad body 2. The bite pad 3 is made of soft material to avoid damaging the patient's teeth. By moving the cannula body 1, the cannula body 1 passes through the tooth pad body 2 and is inserted into the patient's trachea. After the cannula body 1 is inserted into the trachea, the bidirectional threaded rod 5 is reversed to drive the two threaded seats 6 closer to each other, thereby driving the two limit blocks 7 closer to each other, thereby driving the two anti-skid pads 8 closer to each other. The cannula body 1 is limited by two anti-skid pads 8, so that the cannula body 1 is fixed inside the fixing box 4, so that the cannula body 1 cannot move in the tooth pad body 2, thereby avoiding the cannula body 1 from loosening with the tooth pad body 2 during use, and improving the safety of the cannula body 1 during use. The stability of the threaded seat 6 during movement is improved by the first slider 9, and the stability of the connecting block 10 is improved by the second slider 11, thereby improving the stability of the limit block 7 during movement, thereby improving the stability of the anti-skid pad 8 during movement, ensuring that the anti-skid pad 8 can stably fix the cannula body 1, so that when the device moves the cannula body 1, the cannula body 1 can move in the tooth pad body 2, and when the device completes the placement of the cannula body 1, the cannula body 1 and the tooth pad can be placed together. The main body 2 is fixed together, which reduces the probability of the cannula main body 1 loosening and causing hypoxia for the patient, and improves the portability and safety of the cannula main body 1 and the bite pad main body 2 when they are used. When the cannula main body 1 needs to be separated from the bite pad main body 2, the grip 15 is pulled to drive the positioning shaft 14 to move backward, so that the positioning shaft 14 is disengaged from the positioning hole, so that the fixing tube 13 loses its limit, and the rotating rod 12 is driven to rotate through the fixing tube 13, thereby driving the two-way threaded rod 5 to rotate, thereby driving the two anti-skid pads 8 to move away from each other. When the cannula main body 1 and the bite pad main body 2 need to be fixed together, the rotating rod 12 is reversed through the fixing tube 13, thereby driving the two-way threaded rod 5 to reverse, thereby driving the two anti-skid pads 8 to move closer to each other. When the inner side of the anti-skid pad 8 is aligned with the cannula main body 2, the rotation of the two-way threaded rod 5 is reversed. When the outer sides of the body 1 are fitted together, the cannula body 1 and the tooth pad body 2 are fixed together. At this time, the grip 15 is released, and the mounting plate 16 is squeezed by the positioning spring 17, so that the mounting plate 16 moves forward, thereby driving the positioning shaft 14 to move forward, so that the positioning shaft 14 enters the positioning hole, so that the fixing tube 13 is limited, so that the rotating rod 12 and the two-way threaded rod 5 are limited, so that the threaded seat 6, the limiting block 7 and the anti-skid pad 8 are limited, so that the anti-skid pad 8 can be prevented from loosening due to the misrotation of the two-way threaded rod 5, and the stability of the anti-skid pad 8 when placed is improved, so that the device is convenient to improve the stability of the anti-skid pad 8 when placed, and does not affect the movement of the anti-skid pad 8, further improving the stability of the cannula body 1 and the tooth pad body 2 when fixed,This further improves the safety of the cannula body 1 when in use.
