The movable end of the torsion spring 25 abuts against the control handle 23, and the abutting end of the torsion spring 25 abuts against and is fixed to the slider 21.

[0037] The movable channel one 12 arranged on one side of the fixator body 1 can provide a sliding space when the sliding block one 21 drives the fixing mechanism 2 to slide on the fixator body 1 as a whole, so as to avoid touching the skin of the patient during sliding and causing discomfort to the patient. The flexible pad 13 arranged outside the movable channel one 12 can reduce the pressure of the fixator body 1 on the patient. A plurality of limiting teeth 14 grooves are arranged on the fixator body 1. By pressing the movable end of the torsion spring one 25 to the side of the abutting end one through the control handle 23 on both sides of the sliding block one 21, the control handle 23 is rotated around the fixing shaft. At this time, the limiting block connected to the end of the control handle 23 is separated from the limiting teeth 14 groove, so as to release the limitation of the sliding block one 21. The sliding block one 21 can slide in the entire range of the movable channel one 12, so as to adjust the position of the cannula fixing cylinder 22. When the adjusting handle is loosened, the limiting block is pushed into the limiting teeth 14 groove under the rebounding force of the torsion spring, so as to be locked and fixed. By driving the fixing mechanism 2 to slide on the fixator body 1 through the sliding block one 21, it is beneficial for the medical staff to clean and nurse the inside of the oral cavity of the patient.

[0038] On the basis of the first embodiment, in the present embodiment, as shown in Figures 2-5 One end of the cannula fixing cylinder 22 is arranged as a semicircular open pipe. Two groups of clamping grooves are arranged on the semicircular open pipe. Each group of clamping grooves is composed of two arc-shaped grooves 26. The two arc-shaped grooves 26 are on the same arc line. Each group of clamping grooves is provided with the fixing structure 3. The fixing structure 3 includes a locking belt 31 and a lock head 32. One end of the locking belt 31 is fixedly connected to the bottom of the junction of the two arc-shaped grooves 26. The lock head 32 is arranged at the bottom of the end of the locking belt 31. The other end of the locking belt 31 passes through the lock head 32 after passing around the two arc-shaped grooves 26, so as to tightly lock and fix the tracheal cannula.

[0039] A plurality of lock grooves 33 are arranged on the outer wall of the locking belt 31. A lock block 34 for limiting the lock grooves 33 is arranged on the lock head 32. An unlocking handle 35 is connected to the lock block 34. A pin shaft is arranged on the lock head 32. The unlocking handle 35 and an abutting block 36 are respectively arranged on both sides of the pin shaft. The unlocking handle 35 is rotationally installed on the pin shaft. A torsion spring two 37 is also installed on the center of the pin shaft. The movable end of the torsion spring two 37 is connected to the unlocking handle 35. The abutting end of the torsion spring two 37 is fixedly connected to the abutting block 36.

[0040] In use, the tracheal cannula is inserted through the cannula fixing cylinder 22, and then the unlocking handle 35 is pinched to rotate the torsion spring two 37 to the end of the locking band 31. The end of the locking band 31 is sequentially wound around the tracheal cannula and the arc-shaped slot 26 on the other side of each set of clamping slots, and then passes through the lock head 32. At this time, the locking groove 33 on the outer wall of the locking band 31 smoothly passes through the lock head 32 until the tracheal cannula is completely fixed, and then the unlocking handle 35 is released. Under the action of the elastic force of the movable end of the torsion spring two 37, the locking block 34 on the unlocking handle 35 is pushed to limit and fix the locking groove 33. The locking band 31 on each set of clamping slots is locked and fixed by the above operation. Through the above design, the tracheal cannula can be quickly fixed, and the working efficiency is improved. In the embodiment, the two arc-shaped slots 26 in the two sets of clamping slots are relatively arranged on the tracheal cannula fixing cylinder 22, and the two arc-shaped slots 26 are separated by a partition plate at the ends. The locking band 31 is conveniently installed below the partition plate.

[0041] On the basis of example one, as shown in Figure 2 The support frame includes a fixed plate 42, an adjusting rod 43 and a support plate 44. One end of the fixed plate 42 is fixedly connected with the outer wall of the second sliding block 46. The inner side of the flexible arc-shaped plate 4 is provided with a movable slot two 45. The outer wall of the movable slot two 45 is provided with a soft pad. One side of the second sliding block 46 slides in the movable slot. A threaded hole is formed in the center of the fixed plate 42. The adjusting rod 43 is connected with the threaded hole through threads. The adjusting rod 43 passes through the threaded hole and is fixedly connected with the bottom of the support plate 44. The support plate 44 is arranged between the two sets of clamping slots to support the tracheal fixing tube.

[0042] In use, when the locking band 31 locks and fixes the tracheal cannula, the support plate 44 at the top is moved to the direction of the tracheal cannula fixing cylinder 22 by rotating the adjusting rod 43. When the tracheal cannula fixing cylinder 22 is supported to the appropriate position, stop rotating the adjusting rod 43. Further, since the second sliding block 46 and the first sliding block 21 are connected by a connecting rod, when the first sliding block 21 moves on the fixed body 1, the second sliding block 46 moves with it. Even when the patient's oral cavity is cleaned and nursed, the tracheal fixing tube can be continuously supported. In the embodiment, the movable slot two 45 parallel to the movable slot one 12 is arranged on the flexible arc-shaped plate 4, which is beneficial to provide a moving space for the second sliding block 46 when the first sliding block 21 moves.

[0043] The fixed body 1 and the flexible arc-shaped plate 4 are symmetrically provided with pressure prevention pads 5. By arranging the pressure prevention pads 5 on the fixed body 1 and the flexible arc-shaped plate 4, the strong pressure on the patient's skin can be prevented, the patient's discomfort can be improved, and the use comfort of the tracheal cannula fixer is improved.

[0044] The utility model has carried out the exemplary description to the utility model in the above-mentioned combination drawing, obviously the utility model concrete realization is not limited by above-mentioned mode, only if the method conception and technical scheme of the utility model have been used to carry out this kind of non-essential improvement, or the conception and technical scheme of the utility model are directly applied to other occasions without improvement, all are within the protection scope of the utility model.
