[0033] Example 1

[0034] As shown in Figure 1 and Figure 2 , a high-stability head-down decompression frame for postoperative recovery of retinal surgery, comprising: a bottom plate 1, a decompression plate 11 arranged on the top of the bottom plate 1 and a head support mechanism for supporting the head of the patient when lying down and bending over, and a stable lifting assembly eccentrically arranged between the bottom plate 1 and the decompression plate 11; the stable lifting assembly comprises: a lower frame 2 fixed on the top of the bottom plate 1, an upper frame 21 arranged on the top of the lower frame 2, and a plurality of rotating rods 22 and a plurality of sliding rods 23 arranged on the inner sides of the lower frame 2 and the upper frame 21; a plurality of first connecting rods 24 and a plurality of second connecting rods 25 are arranged between the lower frame 2 and the upper frame 21; one end of the first connecting rod 24 is fixed with the rotating rod 22 on the inner side of the lower frame 2, and the other end is fixed with the sliding rod 23 on the inner side of the upper frame 21; one end of the second connecting rod 25 is fixed with the sliding rod 23 on the inner side of the lower frame 2, and the other end is fixed with the rotating rod 22 on the inner side of the upper frame 21; a support assembly for hinged support and swing transmission is arranged between the bottom plate 1 and the decompression plate 11, and a power assembly for driving the sliding rod 23 on the inner side of the lower frame 2 to make reciprocating linear motion is arranged on the top of the bottom plate 1.

[0035] It should be noted that the plurality of rotating rods 22 are respectively rotatably connected to the inner sides of the lower frame 2 and the upper frame 21, and the plurality of sliding rods 23 are respectively slidably connected to the inner sides of the lower frame 2 and the upper frame 21; the middle portions of the first connecting rod 24 and the second connecting rod 25 are hingedly connected; after the patient's body lies prone on the top of the decompression plate 11, a scissor lifting structure is formed by the lower frame 2, the upper frame 21, the rotating rods 22, the sliding rods 23, the first connecting rod 24 and the second connecting rod 25, the bottom plate 1 and the decompression plate 11 are hingedly supported by the cooperation of the supporting assembly, the sliding rod 23 inside the lower frame 2 is driven to make reciprocating linear motion by the cooperation of the power assembly, and the second connecting rod 25 on the side of the sliding rod 23 inside the lower frame 2 is used as a fulcrum formed by the second connecting rod 25 and the rotating rod 22 inside the upper frame 21, and because the middle portions of the first connecting rod 24 and the second connecting rod 25 are hingedly connected, the height of the upper frame 21 can be repeatedly changed when the sliding rod 23 inside the lower frame 2 makes reciprocating linear motion, and the decompression plate 11 can be smoothly swung left and right, which not only ensures the stability of the patient in the prone position, avoids additional pressure or discomfort caused by shaking or instability, but also constantly changes the contact point between the patient's body and the decompression plate 11 through swinging movement, avoids long-term pressure on the same part, helps to disperse the pressure on the patient's body and reduce the feeling of oppression, improves the comfort of the patient, and promotes the stability and repair of the retina in the eye.

[0036] As shown in Figure 2 and Figure 3 in the present embodiment, the supporting assembly includes a plurality of supporting cylinders 3 fixed on the top of the bottom plate 1, a plurality of first swing plates 31 and second swing plates 32 fixed on the bottom of the decompression plate 11, and a floating plate 33 slidably connected on the top of the upper frame 21; the top of the supporting cylinder 3 and the floating plate 33 is fixed with a circular block 34, and the top of the circular block 34 is respectively clamped with the bottom of the first swing plate 31 and the second swing plate 32; the supporting cylinder 3 and the first swing plate 31 are located in the middle of the decompression plate 11, and the second swing plate 32 is located on the top of the upper frame 21.

[0037] It should be noted that the supporting cylinder 3, the first swing plate 31, the second swing plate 32 and the floating plate 33 are provided to achieve the hinged support between the decompression plate 11 and the bottom plate 1, and can transmit left and right swinging, and the clamping of the circular block 34 on the supporting cylinder 3 and the floating plate 33 with the swing plate allows the decompression plate 11 to maintain a relatively stable posture during lifting, while allowing a certain degree of swinging, which utilizes the principle of lever and the characteristics of hinge connection to ensure the stability and safety of the decompression plate 11 during lifting.

[0038] As shown in Figure 4As shown, in this embodiment, the power assembly includes: a servo motor 5 fixed to the top of the base plate 1, a rotating column 51 fixed to the output end of the servo motor 5, and a guide groove 52 opened on the side of the rotating column 51; a push rod 53 is fixed to the side of the sliding rod 23 located inside the lower frame 2, a transmission cylinder 54 is fixed to one end of the push rod 53, a plurality of guide columns 55 are fixed to the inner side of the transmission cylinder 54, and the sides of the plurality of guide columns 55 are slidably connected to the inner side of the guide groove 52.

[0039] It should be noted that the guide groove 52 is wavy along the surface of the rotating column 51 and is connected end to end; the transmission cylinder 54 is sleeved on the side of the rotating column 51; when it is necessary to drive the sliding rod 23 inside the lower frame 2 to make linear motion, the servo motor 5 is started to drive the rotating column 51 to rotate. The guide column 55 is slidably connected to the guide groove 52 on the surface of the rotating column 51. Since the guide groove is wavy along the surface of the rotating column 51 and is connected end to end, the rotational motion can be converted into the reciprocating linear motion of the push rod 53, thereby driving the sliding rod 23 to move within the lower frame 2, thus realizing precise control of the height change of the pressure reducing plate 11.

[0040] like Figure 3 As shown, in this embodiment, a photoelectric component is installed on the base plate 1. The photoelectric component includes: a controller 6 installed on the base plate 1 for issuing control commands according to a preset program, a photoelectric sensor 61 fixed on one side of the lower frame 2, and a metal strip 62 fixed on one side of the upper frame 21; the controller 6 is electrically connected to the photoelectric sensor 61 and the servo motor 5 respectively.

[0041] It should be noted that when the patient is about to end the prone position, the controller 6 is activated, which activates the photoelectric sensor 61. Since the photoelectric sensor 61 continuously emits a light beam, when the metal strip 62, which moves up and down with the upper frame 21, enters the sensing range of the photoelectric sensor 61, the light beam is blocked. The photosensitive element senses the change in light flux and converts it into an electrical signal. After this signal is transmitted to the controller 6, the controller 6 quickly judges according to the preset program and shuts down the servo motor 5 to ensure that the upper frame 21 stops at the correct position, so that the pressure relief plate 11 is in a horizontal state relative to the base plate 1. This prevents the pressure relief plate 11 from being in a tilted state when it stops swinging, which could cause the patient to slip off the pressure relief plate 11, thus ensuring the safety of the patient when using the product.

[0042] It is understood that the control circuit of controller 6 can be implemented by simple programming by those skilled in the art, and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0043] like Figure 2As shown, in the present embodiment, the headrest mechanism comprises: a bottom plate 7 fixed on the top of the bottom plate 1 on one side of the decompression plate 11, a headrest bracket 71 arranged on the top of the bottom plate 1, and a headrest cotton block 72 mounted on the top of the headrest bracket 71; an adjusting assembly is arranged between the bottom plate 7 and the headrest bracket 71 for adjusting the relative height therebetween.

[0044] It should be noted that the material of the headrest cotton block 72 is high-elasticity memory cotton; after the bottom plate 7 and the headrest bracket 71 are placed on the top of the bottom plate 1 on one side of the decompression plate 11, the use of high-elasticity memory cotton for the headrest cotton block 72 can provide better comfort and support for the patient when supporting the head through the headrest bracket 71, and maintain the stable posture of the head.

[0045] In the present embodiment, the adjusting assembly comprises: a plurality of adjusting cylinders 8 fixed on the top of the bottom plate 7, and a plurality of adjusting screws 81 rotatably connected to the bottom of the headrest bracket 71; the bottom end of the adjusting screw 81 is threadedly connected to the inner side of the adjusting cylinder 8.

[0046] It should be noted that the number of adjusting cylinders 8 and adjusting screws 81 is the same and one-to-one correspondence; by rotating the adjusting screw 81, the relative position between it and the adjusting cylinder 8 can be changed, thereby achieving the adjustment of the height of the headrest bracket 71, so that the support position of the headrest bracket 71 for the patient's head meets the requirements of the head-down posture, and improves the individualized needs of the patient.

[0047] When the embodiment is used, the patient's body is prone on the top of the decompression plate 11, at this time, the bottom plate 1, the decompression plate 11, the head support mechanism and the eccentrically arranged stable lifting assembly jointly constitute a support, the stable lifting assembly forms a scissor lifting structure through the lower frame 2, the upper frame 21, the rotating rod 22, the sliding rod 23, the first connecting rod 24 and the second connecting rod 25, when the servo motor 5 is started, the rotating column 51 at the output end rotates, the sliding connection of the wave-shaped guide groove 52 on the side of the rotating column 51 and the guide column 55 inside the transmission cylinder 54 converts the rotating motion into the reciprocating linear motion of the push rod 53, and then drives the linear motion of the sliding rod 23 inside the lower frame 2, the motion formed is transmitted to the upper frame 21 through the middle articulation of the first connecting rod 24 and the second connecting rod 25, so that the height of the upper frame 21 repeatedly changes, driving the decompression plate 11 to sway left and right stably, which not only ensures the stability in the prostration posture, but also disperses the pressure on the patient's body through the swinging motion, improving the comfort. And the support assembly is supported through the articulation of the support cylinder 3, the first swing plate 31, the second swing plate 32 and the floating plate 33, and the clamping of the circular block 34 and the swing plate, which ensures the stability and safety of the decompression plate 11 during lifting. The head support mechanism is used for comfortable support of the patient's head through the bottom disc 7, the head support bracket 71 and the head support cotton block 72, and the height of the head support bracket 71 is adjusted through the adjusting assembly to meet the individual needs of the patient. When the patient needs to end the prone posture, the photoelectric sensor 61 in the photoelectric assembly senses the metal strip 62 on the upper frame 21, the controller 6 turns off the servo motor 5 according to the preset program, so that the decompression plate 11 stops swinging and is in a horizontal state, ensuring the safety of the patient.
