Embodiment 1
[0060] Please refer to the attached figure 1 , with figure 1 It is a structural schematic diagram of a corneal reverse micropore maker in this embodiment. The corneal reverse microhole maker includes an upper handle (1), a lower handle (2), an upper extension rod (3), a lower extension rod (4), an adjustment rod (5), a torsion spring (6), an extension rod Fixed ring (7), adjusting rod fixed ring (8), gasket (9), depth control shaft (10) and punch (20);
[0061] Please refer to the attached figure 2 , attached image 3 , attached Figure 8 , with figure 2 It is a schematic diagram of the combination of the upper end handle, the lower end handle, the upper end extension rod, and the lower end extension rod of a kind of corneal reverse micropore maker in this embodiment. image 3 It is a schematic diagram of the combination of the upper extension rod and the extension rod fixing ring, the adjustment rod and the adjustment rod fixing ring of a corneal reverse microhole mak...
Embodiment 2
[0066] Please refer to the attached figure 1 , attached Figure 9 , with figure 1 It is a schematic structural view of a corneal reverse micropore maker in this embodiment, with Figure 9 It is a plan view of the use of a corneal reverse micropore maker in this embodiment.
[0067] The use process and method of the corneal reverse micropore maker:
[0068] The center of the visual axis of the patient's eye was marked before the operation, and the interface between the graft and the implant bed was determined by OCT, and the thickness from the interface to the corneal endothelial surface was measured. Adjust the drilling depth.
[0069] When the depth control shaft (10) and the punch (20) are completely screwed together, the upper end of the latter is 10 μm higher than the former; according to the required depth, each time the punch (20) is screwed out one turn, the punch (20) moves up 20 μm. During the operation, positioning marks were made on the outer surface of the co...
