[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1 , 2As shown in , 5 and 7, a head pad for thyroid surgery body position placement, comprising a medical bed body 1; a head pad body 11 is installed on the top of the medical bed body 1; a support frame 12 is fixedly connected to the bottom of the medical bed body 1; an adjustment rod 13 is fixedly connected to the bottom of the head pad body 11; the adjustment rod 13 is slidably arranged in the middle of the medical bed body 1 and the support frame 12; a first connecting rod 14 is fixedly connected to the side wall of the support frame 12, and a second connecting rod 15 is fixedly connected to the other side wall; a first sliding rod 16 is rotatably connected to the middle of the first connecting rod 14 and the second connecting rod 15; a tooth block 17 is fixedly connected to the middle of the first sliding rod 16; The tooth block 17 and the adjusting rod 13 are meshed with each other; a bayonet 18 is fixedly connected to the end of the tooth block 17; the bayonet 18 is arranged in a polygonal shape; a clamp 19 matching the shape of the bayonet 18 is fixedly connected to the end of the second connecting rod 15; a handle 110 is fixedly connected to the end of the first sliding rod 16; during work, after the staff puts the medical bed body 1 in the working position, the head pad body 11 can be installed on the top of the medical bed body 1, so that the patient needs to place the neck in the middle of the head pad body 11 during surgery, and support the patient's neck. By setting an adjusting rod 13 at the bottom of the head pad body 11, the patient needs to be adjusted. When adjusting the neck height of the user, the staff can first pull the end of the handle 110. At this time, the first slide bar 16 and the tooth block 17 will slide in and out of the middle of the first connecting rod 14, the second connecting rod 15 and the adjusting rod 13 until the latch 18 is separated from the middle of the clamp 19. At this time, the staff can rotate the handle 110. Because the handle 110 and the first slide bar 16 are fixedly connected, the first slide bar 16 will synchronously drive the tooth block 17 to rotate, and drive the adjusting rod 13 meshed with it to move, thereby adjusting the overall height of the adjusting rod 13 and the head pad body 11. When the adjustment is completed, the staff can push The end of the handle 110 allows the pin 18 to be stuck in the middle of the clamp 19 again, and the first slide bar 16 is fixed as a whole, thereby completing the height adjustment of the head pad body 11. This step is combined with the first slide bar 16 that is rotatably arranged at the bottom of the medical bed body 1, which can improve the flexibility of the head pad body 11 during work, reduce the problem of limited field of vision of medical staff during surgery on patients due to the low height of the patient's neck, reduce the difficulty of surgery and increase the risk. At the same time, combined with the polygonal pin 18, it can improve the convenience of medical staff and patients in fixing the head pad body 11.

[0029] like Figure 1 , 2, 3, 4 and 7, a dual-axis motor 2 is installed at the end of the adjusting rod 13; a gas collecting plate 21 is fixedly connected to the bottom of the adjusting rod 13; the middle part of the gas collecting plate 21 is horn-shaped; a hose 22 is fixedly connected to the end of the gas collecting plate 21; a fixing member 23 is fixedly connected to the side wall of the medical bed body 1; a connecting pipe 24 is fixedly connected to the middle part of the fixing member 23; the connecting pipe 24 and the hose 22 are fixedly connected and connected; a plurality of groups of discharge pipes 25 are fixedly connected to the middle part of the connecting pipe 24; the middle part of the discharge pipe 25 is The adjusting rod 13 is arranged in an inclined shape; a reinforcement frame 26 is fixedly connected to the end of the adjusting rod 13; the reinforcement frame 26 is arranged in an arc shape; a filter screen 27 is fixedly connected to the inner wall of the reinforcement frame 26; a plurality of rotating fans 28 are fixedly connected to the middle of the output end of the dual-axis motor 2; when working, by arranging a dual-axis motor 2 at the end of the adjusting rod 13, when there is no patient on the top of the medical bed body 1, the staff can turn on the dual-axis motor 2 switch, so that the output end of the dual-axis motor 2 will drive the rotating fan 28 to rotate, and generate blowing during the rotation. The wind will pass through the air collecting plate 21 and transfer to the inside of the hose 22 and the connecting pipe 24, and transfer the wind force to the bottom area of ​​the head pad body 11 along the multiple sets of exhaust pipes 25, and blow away the sweat or impurities contained in the head pad body 11. At the same time, the top of the rotating fan 28 will generate suction during the rotation process, and the dust floating in the area of ​​the adjusting rod 13 and the tooth block 17 will be adsorbed to the middle part of the arc-shaped filter screen 27, and then removed in and out. This step cooperates with the wind force discharged from the end of the exhaust pipe 25 to Improve the dryness of the head pad body 11 after long-term use, reduce the problem of long-term accumulation of sweat or impurities in the backlight area at the bottom of the head pad body 11, which makes it easy for bacteria or parasites to grow inside the head pad body 11, and reduce the number of times the staff frequently cleans the middle part of the head pad body 11. At the same time, the rotating fan 28 can clean the adjustment rod 13 and the tooth block 17, reduce the adhesion of some dust to the middle part of the tooth block 17, cooperate with the arc-shaped filter screen 27 and reduce the phenomenon of impurities entering the middle part of the rotating fan 28.

[0030] like Figure 7As shown, the middle of the first connecting rod 14 is fixedly connected to the sliding rail 3; the middle of the first connecting rod 14 and the sliding rail 3 is provided with a sliding groove 31; the middle of the handle 110 is rotatably connected to the handle 110; the middle of the handle 110 is fixedly connected to a rotating drum 32; the inner wall of the sliding groove 31 is slidably connected to a ball 33; the middle of the ball 33 is fixedly connected to an elastic rope 34, and the other end of the elastic rope 34 is fixedly connected to the middle of the rotating drum 32; during operation, by providing a rotatable drum 32 in the middle of the handle 110, the entire length of the elastic rope 34 will be stretched when the staff pulls the first sliding rod 16, and then when the staff rotates the handle 110, the end of the elastic rope 34 The sphere 33 will slide inside the slide groove 31 until the staff pushes the handle 110 to reset the position of the latch 18. In combination with the reaction force generated by the elastic rope 34 being stretched, the handle 110 can be positioned close to the middle of the first connecting rod 14. This step, in combination with the reaction force generated by the elastic rope 34 being stretched, can improve the stability of the latch 18 being stuck in and out of the middle of the clip 19, thereby reducing the problem of the latch 18 and the clip 19 being separated and driving the adjustment rod 13 to drop linearly due to the inertia of movement when the staff transfers the overall position of the medical bed body 1, thereby improving the stability of the head pad body 11 during use.

[0031] like Figure 3 and 4 As shown, the inner wall of the adjusting rod 13 is fixedly connected with a connecting plate 4; the middle of the connecting plate 4 is rotatably connected with a rotating shaft 41; the middle of the rotating shaft 41 and the output end of the dual-axis motor 2 are rotatably connected with a belt 42; the middle of the rotating shaft 41 is fixedly connected with a plurality of telescopic rods 43, and the telescopic rods 43 are staggered in the middle of the rotating shaft 41; the ends of the telescopic rods 43 are fixedly connected with a counterweight block 44; when working, by arranging a rotatable rotating shaft 41 on the inner wall of the adjusting rod 13, the dual-axis motor 2 can synchronously drive the rotating shaft 41 to rotate inside the adjusting rod 13 in cooperation with the belt 42 when working, When the rotating shaft 41 rotates, the multiple groups of counterweight blocks 44 in the middle will hit the inner wall of the adjusting rod 13 in turn, and the telescopic rod 43 will be squeezed and retracted during the collision, and this process is repeated. This step cooperates with the vibration force generated by the counterweight blocks 44 hitting the inner wall of the adjusting rod 13, and the impurities attached to the inner groove of the adjusting rod 13 and agglomerated can be cleaned up, reducing the problem of jamming when the tooth block 17 and the adjusting rod 13 are meshed due to the accumulation of more impurities in the inner groove of the adjusting rod 13 after long-term use, thereby improving the working stability between the adjusting rod 13 and the tooth block 17.

[0032] like Figure 4 and 6As shown, the end of the adjusting rod 13 is fixedly connected with a bracket 5; the middle part of the bracket 5 is arranged in an inclined shape; the middle part of the bracket 5 is threadedly connected with a screw rod 51; the end of the screw rod 51 is rotatably connected to the limiting frame 52; the hose 22 is arranged in the middle of the limiting frame 52; when working, by arranging the bracket 5 at the end of the adjusting rod 13, the limiting frame 52 will support the redundant hose 22, so that when the staff needs to adjust the working position of the limiting frame 52, the staff can use a tool to rotate the end of the screw rod 51. This causes the edge of the screw 51 to extend upward or downward, and during the movement of the screw 51, the end of the screw 51 can be rotated by utilizing the downward gravity of the limit frame 52. This step, combined with the limit frame 52 that supports the entry and exit of the middle part of the hose 22, can reduce the phenomenon that the middle part of the hose 22 is too long and appears to fall and hang in the air, and reduce the problem of bending in the middle part of the hose 22, which causes trouble in venting air from the middle part of the hose 22. At the same time, combined with the rotating screw 51, the limit frame 52 can improve the flexibility of the normal hose 22.

[0033] like Figure 3 As shown, a third connecting rod 6 is fixedly connected to the bottom of the rotating shaft 41; a frame plate 61 is fixedly connected to the middle of the third connecting rod 6; and an adhesive plate 62 is fixedly connected to the inner wall of the frame plate 61. During operation, by arranging the third connecting rod 6 at the bottom of the rotating shaft 41, the belt 42 will synchronously drive the third connecting rod 6 and the frame plate 61 to rotate when rotating, and the adhesive plate 62 will adhere the dust floating in the air after the counterweight block 44 hits it to the middle of the adhesive plate 62 during the rotation process. This step, combined with the adhesive plate 62 with stickiness, can further improve the cleanliness of the working environment of the medical bed body 1 and reduce the problem of secondary dust caused by cleaning the impurities that fall directly.

[0034] like Figure 2 As shown, two groups of reinforcement plates 7 are fixedly connected to the bottom of the head pad body 11; a second slide bar 71 is fixedly connected to the bottom of the reinforcement plate 7; the second slide bar 71 is slidably arranged in the middle part of the medical bed body 1; during operation, two groups of reinforcement plates 7 are arranged at the bottom of the head pad body 11, so that when the head pad body 11 moves upward, the two groups of reinforcement plates 7 and the second slide bar 71 arranged at the bottom will also move synchronously and support the edge of the head pad body 11. This step can be combined with the second slide bar 71 to limit the active area of ​​the head pad body 11 again, thereby improving the flexibility of the head pad body 11 during operation. At the same time, the middle part of the head pad body 11 can be reinforced in and out in combination with the reinforcement plate 7, thereby reducing the phenomenon that the middle part of the head pad body 11 is suspended in the air for a long time, resulting in bending and deformation in the middle part that is difficult to reset.

[0035] like Figure 6As shown, a connecting frame 8 is fixedly connected to the middle part of the bracket 5; a cleaning plate 81 is fixedly connected to the end of the connecting frame 8; the inner wall of the cleaning plate 81 is arranged in contact with the middle part of the screw 51; when working, by arranging the connecting frame 8 at the end of the bracket 5, the cleaning plate 81 can clean the inner wall of the screw 51 and remove the protrusions in the middle part of the screw 51 when the screw 51 is rotated or riding. This step cooperates with the cleaning plate 81 arranged in contact with the middle part of the screw 51 to reduce the problem of more rust spots accumulated in the middle part of the screw 51, which causes greater resistance when the staff rotates the screw 51.

[0036] like Figure 6 As shown, a sponge pad 9 is fixedly connected to the inner wall of the limit frame 52; the inner wall of the sponge pad 9 is arranged to be in contact with the middle part of the hose 22; during operation, by arranging the sponge pad 9 in the middle part of the limit frame 52, when the hose 22 slides in the middle part of the limit frame 52, its surface will be in contact with the sponge pad 9 of soft material. This step, combined with the sponge pad 9 of soft material, can reduce the problem of the hose 22 being scratched by the edge of the limit frame 52 when it moves in and out of the middle part of the limit frame 52, thereby improving the smoothness of the surface of the hose 22.

[0037] Working principle: after the medical bed body 1 is placed in the working position, the head pad body 11 can be installed on the top of the medical bed body 1, so that the patient needs to place the neck in the middle of the head pad body 11 during surgery and support the patient's neck. By setting an adjustment rod 13 at the bottom of the head pad body 11, when the height of the patient's neck needs to be adjusted, the staff can first pull the end of the handle 110. At this time, the first slide bar 16 and the tooth block 17 will slide in and out in the middle of the first connecting rod 14, the second connecting rod 15 and the adjusting rod 13 until the pin 18 is separated from the middle of the clamp 19. At this time, the staff can rotate the handle 110. Because the handle 110 and the first slide bar 16 are fixedly connected, the first slide bar 16 will synchronously drive the tooth block 17. The first slide bar 16 is fixed to the first slide bar 16, and the height adjustment work of the headrest body 11 is completed. By arranging a double-axis motor 2 at the end of the adjusting rod 13, when there is no patient on the top of the medical bed body 1, the staff can turn on the double-axis motor 2 switch, so that the output end of the double-axis motor 2 will drive the rotating fan 28 to rotate, and generate blowing during the rotation. The blowing will pass through the air collecting plate 21 and then be transferred to the inside of the hose 22 and the connecting pipe 24, and the wind will be transferred to the inside of the multiple sets of exhaust pipes 25. The bottom area of ​​the head pad body 11 is blown away, and the sweat or impurities contained in the head pad body 11 are blown away. At the same time, the top of the rotating fan 28 generates suction during the rotation process, and the dust floating in the area of ​​the adjusting rod 13 and the tooth block 17 is adsorbed to the middle part of the arc-shaped filter screen 27 for removal. By providing a rotatable cylinder 32 in the middle of the handle 110, the overall length of the elastic rope 34 will be stretched when the staff pulls the first slide bar 16. Subsequently, when the staff rotates the handle 110, the ball 33 at the end of the elastic rope 34 will slide inside the slide groove 31 until the staff pushes the handle 110 to reset the pin 18, and the handle 110 can be pulled back to the original position with the reaction force generated by the stretched elastic rope 34. The position is close to the middle of the first connecting rod 14, and a rotatable shaft 41 is provided on the inner wall of the adjusting rod 13, so that when the dual-axis motor 2 is working, the belt 42 will synchronously drive the shaft 41 to rotate inside the adjusting rod 13, and when the shaft 41 rotates, the multiple groups of counterweights 44 in the middle will hit the inner wall of the adjusting rod 13 in turn, and the telescopic rod 43 will be squeezed and retracted during the collision, and this is repeated. By providing a bracket 5 at the end of the adjusting rod 13, and the limit frame 52 will support the redundant hose 22, when the staff needs to adjust the working position of the limit frame 52, the staff can use a tool to rotate the end of the screw 51, so that the edge of the screw 51 will extend upward or downward.In addition, during the movement of the screw rod 51, the downward gravity of the limit frame 52 can be used to rotate the end of the screw rod 51. By providing a third connecting rod 6 at the bottom of the rotating shaft 41, the belt 42 can synchronously drive the third connecting rod 6 and the frame plate 61 to rotate when rotating. In the process of rotation, the sticking plate 62 can adhere the dust floating in the air after the counterweight block 44 hits to the middle of the sticking plate 62. By providing two sets of reinforcing plates 7 at the bottom of the head pad body 11, the head pad body 11 can move upward. When the headrest 11 is moved, the two sets of reinforcing plates 7 and the second slide bar 71 at the bottom will also move synchronously and support the edge of the headrest body 11. By setting a connecting frame 8 at the end of the bracket 5, when the screw 51 is rotating or riding, the cleaning plate 81 will clean the inner wall of the screw 51 and remove the protrusions in the middle of the screw 51. By setting a sponge pad 9 in the middle of the limiting frame 52, when the hose 22 slides in the middle of the limiting frame 52, its surface will be in contact with the sponge pad 9 made of soft material.
