Embodiment 1

[0024] Embodiment 1: as Figure 1 to Figure 3 As shown, a gas-permeable amniotic mirror includes a conjunctival sac support device, the conjunctival sac support device is annular and fits the curvature of the ocular surface, and the conjunctival sac support device includes an arc ring 1 and a fixed ring 2, and the through hole 3 is provided on the said arc ring 1. The shape of the arc ring 1 can fully fit the sclera. The through-holes 3 are evenly arranged along the circumferential direction, and generally the number is an even number, preferably 4 or 6, and the number of through-holes 3 in this implementation is 6. The fixing ring 2 is provided with a fixing groove 4 matching with the amniotic membrane. The inner circle part of the conjunctival sac supporting device can fully expose the cornea. When the amniotic membrane is installed, the amniotic membrane is placed inside the conjunctival sac support device, and then the edge of the amniotic membrane extending out of the ...

Embodiment 2

[0025] Embodiment 2: Compared with Embodiment 1, in Embodiment 2, a channel is added on the bottom surface of the conjunctival sac supporting device contacting the ocular surface, so as to drain the subamniotic fluid.

Embodiment 3

[0026] Embodiment 3: as Figure 1 to Figure 3 As shown, a gas-permeable amniotic mirror includes a conjunctival sac support device, the conjunctival sac support device is ring-shaped and fits the curvature of the ocular surface, and the conjunctival sac support device includes an arc ring 1 and a fixed ring 2, and the through hole 3 is provided on the said arc ring 1. The shape of the arc ring 1 can fully fit the sclera. The through-holes 3 are evenly arranged along the circumferential direction, and generally the number is an even number, preferably 4 or 6, and the number of through-holes 3 in this implementation is 6. The fixing ring 2 is provided with a fixing groove 4 matching with the amniotic membrane. The inner circle part of the conjunctival sac supporting device can fully expose the cornea. When the amniotic membrane is installed, the amniotic membrane is placed inside the conjunctival sac support device, and then the amniotic membrane is sewn on the arc ring throu...

Abstract

The invention discloses a breathable amnioscope, and relates to medical instruments. The breathable amnioscope comprises a conjunctival sac supporting device. The conjunctival sac supporting device isannular and attached to the radian of the ocular surface. A plurality of through holes are formed in the conjunctival sac supporting device. Compared with the prior art, the breathable amnioscope ofthe present invention can drain effusion generated by the ocular surface below the conjunctival sac supporting device, and can conduct ventilation and air exchange on the lower part of the conjunctival sac supporting device, thereby inhibiting breeding of anaerobic bacteria. The breathable amnioscope solves the problem that apocenosis and ventilation cannot be achieved in the prior art.

Description

technical field [0001] The invention relates to a medical device, in particular to an amniotic mirror. Background technique [0002] The amniotic membrane is the part of the fetal membrane in contact with the amniotic fluid, differentiated from trophoblast cells, with a thickness of 0.02 mm -0.05 mm, translucent, tough, without blood vessels, nerves, and lymphatic vessels. The amniotic membrane is divided into five layers: epithelial cell layer, basement membrane, parenchymal layer, fibroblast layer and spongy layer. Amnion has the functions of promoting epithelial repair, inhibiting scar formation, inhibiting corneal neovascularization, and inhibiting immune response. Therefore, amnion coverage and amnion transplantation are widely used in the treatment of ocular surface diseases and have achieved good clinical efficacy. However, the means of fixing the amniotic membrane in amniotomy covering surgery in clinical application at present is mainly surgical suturing, which wil...
