[0020] It should be noted that the specific installation methods and ways, the circuit connection methods, and the control methods of the electric telescopic rod 1-2 and the electric telescopic rod 4-6 in the present invention are all conventional designs and are the conventional design means of designers.

[0021] First, put the fixing group 5 on the head of the operating bed. Then, start the electric telescopic rod 4-6 to tightly fix the fixing group 5. Next, start the electric telescopic rod 1-2 and cooperate with the rotating base 1 to support the whole device. In addition, part of the head of the operating bed can be flipped. Medical staff can adjust the electric telescopic rod 1-2 according to actual needs and with the cooperation of the rotating base 1 and the support frame 7, so that the electric telescopic rod 1-2 drives the support frame 7 to always support the whole device, further increasing the stability of the device. Fix the patient's head through the fixing mechanism 3, and can adjust the height of the patient's head and neck position. And through the support mechanism 4, cooperate with the fixing group 5 to support the patient's oral cavity without the need for medical staff to hold it manually, reducing the workload of medical staff. Each structure is used in cooperation, so that the device can be applied to surgeries in parts such as the nasal cavity and oral cavity and pharynx.

[0022] In order to fix the whole device on the head of the operating bed, as Figure 2 shown, the fixing group 5 includes an outer shell two 51. Installation grooves four 53 are jointly opened at the left and right ends and the rear end of the outer shell two 51. A side clamping tooth rod one 54 is slidably connected to the upper side of the inner cavity of the installation groove four 53. A side clamping tooth rod two 58 is slidably connected to the lower side of the inner cavity of the installation groove four 53. A tooth roller two 52 is jointly meshed and connected to the mutually approaching sides of the outer surfaces of the side clamping tooth rod two 58 and the side clamping tooth rod one 54. The outer surface of the tooth roller two 52 is rotatably connected to the inner cavity of the installation groove four 53. Circular grooves 55 are fixedly connected to the upper ends of the side clamping tooth rod one 54 and the front sides of the upper ends of the side clamping tooth rod two 58. Quick heads 56 are fixedly connected to the output ends of the two circular grooves 55. A cross bar 57 is jointly provided in the inner cavities of the two quick heads 56. The front end of the outer shell two 51 is fixedly connected to the rear end of the support frame 7. The rear end of the outer shell two 51 is fixedly connected to the front end of the electric telescopic rod 4-6. The output end of the electric telescopic rod 4-6 includes a connection block, and the connection block penetrates through the inner cavity of the installation groove four 53 and is fixedly connected to the right side of the rear end of the side clamping tooth rod one 54.

[0023] It should be noted that the specific installation methods and ways, the circuit connection methods, and the control methods of the circular groove 55 in the present invention are all conventional designs and are the conventional design means of designers.

[0024] It should be noted that the crossbar 57 and the two quick connectors 56 can be quickly spliced or disassembled. Whether to install the crossbar 57 can be determined according to the surgical needs. First, the side clamping tooth bar one 54 and the side clamping tooth bar two 58 are clamped on the head of the operating bed. Then, the electric telescopic rod four 6 is started, and the connecting block in the electric telescopic rod four 6 drives the side clamping tooth bar one 54 to contract into the inner cavity of the installation groove four 53, and at the same time drives the tooth roller two 52 to rotate. Through the rotation of the tooth roller two 52, the side clamping tooth bar two 58 is driven to contract into the inner cavity of the installation groove four 53 at the same time until the side clamping tooth bar two 58 and the side clamping tooth bar one 54 are tightly clamped on the head of the operating bed to achieve the purpose of fixation.

[0025] Embodiment 2. On the basis of Embodiment 1, this embodiment realizes the fixation of the patient's head, as Figure 3 shown. The fixing mechanism 3 includes a fixing plate 31. An installation groove one 34 is opened at the upper end of the fixing plate 31. A rotating member 32 is rotatably connected to the lower side of the inner cavity of the installation groove one 34. Transmission members 33 are rotatably connected to the rear and middle parts of the inner cavity of the installation groove one 34. The lower sides of the outer surfaces of the two transmission members 33 are jointly meshed with the rotating member 32. A top block 35 is jointly provided between the outer surface of the rear transmission member 33 and the rear part of the inner cavity of the installation groove one 34. A headrest 36 is jointly provided between the outer surface of the middle transmission member 33 and the middle part of the inner cavity of the installation groove one 34. Symmetric auxiliary rods 38 are fixedly connected to the front side of the inner cavity of the installation groove one 34. A clamping group 37 is jointly provided between the outer surfaces of the two auxiliary rods 38 and the front side of the inner cavity of the installation groove one 34. The lower end of the fixing plate 31 is fixedly connected to the upper end of the support frame 7.

[0026] It should be noted that the transmission member 33 is composed of a bevel gear and a threaded rod, and the threaded rods in the two transmission members 33 have opposite helix directions. The rotating member 32 is composed of a rotating rod and two bevel gears. By rotating the rotating member 32, the two transmission members 33 are rotated simultaneously, and the top block 35 and the headrest 36 are driven to move one upward and one downward in the inner cavity of the installation groove one 34.

[0027] First, after the medical staff fix the device on the operating bed through the fixing group 5, the patient is placed on the operating bed, and the patient's head is rested on the headrest 36. The top block 35 supports the patient's neck, and the clamping group 37 fixes the patient's head. According to the needs, the rotating member 32 is rotated to drive the two transmission members 33 to rotate simultaneously, so that the top block 35 rises in the inner cavity of the installation groove one 34, and the headrest 36 moves downward in the inner cavity of the installation groove one 34, so that the patient makes a head-up movement. At the same time, because the clamping group 37 fixes the patient's head, the clamping group 37 will slide backward on the front side of the inner cavity of the installation groove one 34 and the outer surfaces of the two auxiliary rods 38, which does not affect the patient's head-up movement. Overall, it achieves the purpose of facilitating the doctor to perform nasal or oral related surgeries on the patient, making the device more flexible to use.

[0028] Further explanation, asFigure 4 and Figure 5 As shown in Figure 5 , the clamping group 37 includes a first housing 371. In the middle of the front end of the first housing 371, there are symmetrically arranged through holes 376 on the left and right. In the middle of the inner cavity of the first housing 371, a first toothed roller 377 is rotatably connected. On the upper side of the inner cavity of the first housing 371, an L-shaped first toothed rod 372 is slidably connected. On the lower side of the inner cavity of the first housing 371, an L-shaped second toothed rod 374 is slidably connected. On the mutually approaching sides of the outer surfaces of the L-shaped first toothed rod 372 and the L-shaped second toothed rod 374, they are jointly meshed with the outer surface of the first toothed roller 377. On the mutually approaching sides of the upper parts of the outer surfaces of the L-shaped first toothed rod 372 and the L-shaped second toothed rod 374, clamping components 373 are rotatably connected. On the upper side of the front end of the first housing 371, a first chute 3791 is provided. On the left side of the front end of the first housing 371, a second electric telescopic rod 379 is fixedly connected. The output end of the second electric telescopic rod 379 is fixedly connected with an L-shaped connecting rod 378. The rear end of the L-shaped connecting rod 378 penetrates through the inner cavity of the first chute 3791 and is fixedly connected with the right side of the front end of the L-shaped second toothed rod 374. On the upper left side of the inner cavity of the first housing 371, a support block 375 is fixedly connected. The upper end of the support block 375 is in contact with the lower end of the L-shaped second toothed rod 374. The inner cavities of the two through holes 376 are respectively slidably connected with the outer surfaces of the two auxiliary rods 38. The outer surface of the first housing 371 is slidably connected with the front side of the inner cavity of the first installation groove 34.

[0029] It should be noted that the clamping component 373 is composed of a rotating housing, a pressure sensor, and a rubber clamping pad. The specific installation method, the connection method of the circuit, and the control method of the pressure sensor and the second electric telescopic rod 379 in the clamping component 373 of the present invention are all conventional designs and are the conventional design means of designers. The pressure sensor and the second electric telescopic rod 379 in the clamping component 373 cooperate with each other. When the pressure detected by the pressure sensor reaches the preset value, the second electric telescopic rod 379 stops compressing, so that the L-shaped first toothed rod 372 and the L-shaped second toothed rod 374 no longer drive the clamping component 373 to continue pressing on the patient's head.

[0030] Specifically, by starting the second electric telescopic rod 379, the L-shaped connecting rod 378 is driven to move to the right in the inner cavity of the first chute 3791, and the L-shaped second toothed rod 374 is driven to move to the right between the upper side of the inner cavity of the first housing 371 and the upper end of the support block 375, thereby driving the first toothed roller 377 to rotate. Through the rotation of the first toothed roller 377, the L-shaped first toothed rod 372 is driven to move to the left in the inner cavity of the first housing 371, so that the two clamping components 373 clamp and fix the patient's head to an appropriate pressure. When the patient makes a head-up movement by cooperating with the top block 35 and the headrest 36, the first housing 371 will be driven to move backward in the inner cavity of the first installation groove 34 in cooperation with the through holes 376 and the auxiliary rods 38, and the clamping component 373 rotates on the L-shaped first toothed rod 372 and the L-shaped second toothed rod 374 following the patient's head.

[0031] Embodiment 3. On the basis of Embodiment 1 and Embodiment 2, this embodiment completes the support for the patient's oral cavity, as Figure 6 , Figure 7 and Figure 8 shown. The support mechanism 4 includes a hook plate 41. A connecting plate 42 is fixedly connected to the front end of the hook plate 41. An installation groove II 43 is opened at the upper end of the connecting plate 42. A sliding group 44 is slidably connected to the inner cavity of the installation groove II 43. A top plate II 45 is fixedly connected to the front side of the lower end of the connecting plate 42. A housing III 48 is fixedly connected to the middle right side of the inner cavity of the installation groove II 43. A spring 49 is fixedly connected to the inner cavity of the housing III 48. A gear roller III 47 is fixedly connected to the left end of the spring 49. The outer surface of the gear roller III 47 is slidably connected to the inner cavity of the housing III 48. The left end of the gear roller III 47 penetrates through the inner cavity of the installation groove II 43 and is fixedly connected to a pressure rod 46. The inner cavity of the hook plate 41 is slidably connected to the outer surface of the cross bar 57.

[0032] First, with the cooperation of the fixing mechanism 3 and the fixing group 5, the patient's head is fixed and the patient is made to tilt his head back to an appropriate angle for the operation. Then, the front lower part of the top plate II 45 and the sliding group 44 are placed into the patient's mouth, so that the top plate II 45 abuts against the upper jaw teeth of the patient, and the front lower part of the sliding group 44 abuts against the lower jaw teeth of the patient. Then, the pressure rod 46 is pressed, so that the pressure rod 46 drives the gear roller III 47 to slide in the inner cavity of the housing III 48 and compress the spring 49, and the gear roller III 47 disengages from the lower side of the sliding group 44 and no longer restricts the position of the sliding group 44. Then, the sliding group 44 is slid to open the patient's oral cavity to an appropriate size. Then, the pressing on the pressure rod 46 is released. Under the elastic force of the spring 49, the gear roller III 47 returns to its initial position and restricts the movement of the sliding group 44 again, completing the fixation of the opening size of the patient's oral cavity. Then, the circular groove 55 is started to extend to an appropriate height, and then the cross bar 57 is installed on the quick connector 56. Finally, the entire support mechanism 4 is clamped at an appropriate position on the outer surface of the cross bar 57 through the hook plate 41, completing the fixation of the support mechanism 4, eliminating the need for medical staff to hold it manually, reducing the workload of medical staff and facilitating the operation of doctors.

[0033] Further explanation, as Figure 9 and Figure 10 shown. The sliding group 44 includes a T-shaped push plate 441. A rectangular groove 442 is opened at the rear side of the lower end of the T-shaped push plate 441. A toothed plate 443 is fixedly connected to the left side of the top wall of the inner cavity of the rectangular groove 442. A top plate I 444 is fixedly connected to the front side of the lower end of the T-shaped push plate 441. A chute II 448 is opened at the front side of the upper end of the T-shaped push plate 441. A baffle 447 is slidably connected to the inner cavity of the chute II 448. An installation groove III 446 is opened at the front side of the bottom wall of the inner cavity of the chute II 448. A tongue depressor 445 is slidably connected to the inner cavity of the installation groove III 446. The outer surface of the T-shaped push plate 441 is slidably connected to the inner cavity of the installation groove II 43. The lower side of the outer surface of the toothed plate 443 is meshed with the gear roller III 47.

[0034] Specifically, first, it is necessary to determine whether it is necessary to press the patient's tongue during the operation before using the support mechanism 4 to avoid affecting the doctor's operation. When it is necessary to press the patient's tongue, slide 477 backward in the inner cavity of 488, then install the tongue depressor 445 clip in the appropriate position in the inner cavity of the third tongue depressor installation groove 446, and then push the baffle 447 back to its initial position to restrict the movement of the tongue depressor 445. Then, press the first top plate 444 against the patient's lower jaw teeth and make the tongue depressor 445 press the patient's tongue. By pressing the pressure rod 46, drive the third gear roller 47 to slide to the right to disengage from the lower side of the outer surface of the toothed plate 443, and then push the T-shaped push plate 441 to slide backward in the second installation groove 43, thereby driving the first top plate 444 to push the patient's lower jaw and upper jaw to separate to an appropriate angle, and finally achieving the purpose of supporting the size of the patient's oral cavity.
