Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments, but the present invention is not limited thereto.
The structure, ratio, size and the like shown in the drawings attached to the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by people familiar with the art, and are not used for limiting the limit conditions which can be implemented by the present invention, so that the actual meaning is not available, and the modification of any structure, the change of ratio relationship or the adjustment of size should still fall within the range which can be covered by the technical content disclosed by the present invention without affecting the efficacy which can be produced by the present invention and the purpose which can be achieved by the present invention. In addition, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are used for the sake of clarity only, and are not intended to limit the scope of the present invention, and the relative relationship between the terms may be changed or adjusted without substantial technical changes.
As shown in fig. 1 to 5, a novel intraocular pressure device according to a preferred embodiment includes: the device comprises a fixed frame 1, a top pressing rod 2 and a top pressing head 3.
The upper end of the fixed frame 1 is provided with an annular groove 4, and the outer wall of the annular groove 4 is provided with a spiral guide rail 6; one end of the jacking rod 2 is provided with a guide block 5; the guide block 5 is arranged on the spiral guide rail 6; the other end of the jacking rod 2 is provided with a jacking head 3.
In the in-service use process, at first place the one side that fixed frame 1 has annular groove 4 towards the outside of eyeball, secondly sew fixed frame 1 on the eyeball for fixed frame 1 is fixed, because top pressure head 3 accessible guide block 5 comes out from helical guideway 6, and top pressure head 3 can 360 rotate in annular groove 4, then with top pressure head 3 from annular groove 4 roll out, carry out the roof pressure to the fat of orbit department, because top pressure head 3 can 360 rotate in annular groove 4, so can rotate top pressure head 3 as required, make top pressure head 3 will need to be pushed up by the orbit department roof pressure of roof pressure.
