Since the adjusting module a unit and the adjusting module B unit are symmetrical along the Y direction, and the structure and the effect are completely the same, we will describe in detail only one side, i.e. the adjusting module a unit, as an example.
As shown in figure 3, a sliding rail 112-1 is arranged in the groove 111-1, a positioning screw 32-1 is arranged on the sliding block 31-1, the positioning screw 32-1 penetrates through the sliding block 31-1 and fixes the sliding block at a certain position of the groove 111-1, and the right end face of the sliding block 31-1 is fixedly connected with the left end of the eyelid support 20. One end of the angle adjustment sheet 33-1 is fixed with the right end face of the sliding block 31-1 through an adjustment screw 34-1.
Wherein, the angle adjustment sheet is made of titanium alloy.
Figure 5 is a schematic view of the angle between the eyelid support and the eyeglass frame in an embodiment of the utility model.
As shown in fig. 5, in the initial state, the angle between the plane of the eyelid support 20 and the plane of the spectacle frame 11 is 90 °. The eyelid support member 20 is rotated upward or downward by the angle adjustment sheet 33-1, and the included angle between the plane of the eyelid support member 20 and the Y-plane of the eyeglass frame 11 is 60 to 120.
Fig. 6 is a schematic view of patient wear in an embodiment of the utility model.
As shown in fig. 6, the present embodiment provides an adjustable eyelid rest that can be used as follows:
when in use, the glasses frame 20 is firstly worn on the head of a patient in the same way as the existing glasses.
After the spectacle frame 20 is worn, the elastic binding strip 1 can be selected to further fix the spectacle frame 20, or the elastic binding strip 1 can be not used, which is selected according to the sizes of the spectacle frame 20 and the face and the head of a patient, and finally, the spectacle frame can be firmly fixed on the face of the patient, and the patient feels the most comfortable.
The left eye is taken as an example to illustrate the specific embodiment of the adjustable bracket provided by the utility model. The doctor first unscrews the two set screws 32-1 and 33-2 and the two adjusting screws on the adjusting assembly 30, then finds the drooping position of the eyelid of the patient, then continuously moves the positions of the left and right sets of sliders 31-1 and 31-2, adjusts the horizontal position and the bending degree of the eyelid supporting member 40, and enables the center of the eyelid supporting member 20 to be close to the center of the drooping position of the eyelid of the patient, thereby completing the coarse adjustment. The rotating angle adjustment sheet is rotated again for fine adjustment, that is, the rotating angle adjustment sheet is rotated upward or downward, so that the eyelid support 20 is correspondingly tilted upward (i.e., tilted toward the overhead direction) or tilted downward (i.e., tilted toward the chin direction), and is adjusted to align the center of the eyelid support 20 with the drooping center of the eyelid, so that the eyelid support 20 and the eyelid of the person are in contact with each other with proper position and strength. The surgeon manually fixes the position of the two sliders 31-1, 31-2 and the eyelid support 20, removes the device, and secures the adjustment assembly 30 by tightening the two set screws 32-1, 33-2 and the two adjustment screws.
By the above adjustment, the drooping eyelid of the patient is lifted up by the elastic force of the eyelid support 20, and the state of the eyelid at the lower end of the drooping center of the eyelid at this time is equivalent to the state of the eyelid in the normal state, so that the eyelid can be supported while objects can be normally seen, and the natural closure of the eyelid is not affected.
