Description

Laminating formula amniotic membrane mirror

Technical Field

The invention relates to a medical instrument, in particular to a amniocentoscope.

Background

The amnion is the contact part of the fetal membrane and amniotic fluid, is differentiated from trophoblasts, has a thickness of 0.02-0.05 mm, is semitransparent, and has toughness, no blood vessel, no nerve and no lymphatic vessel. The amnion is divided into five layers: epithelial cell layer, basement membrane, parenchymal layer, fibroblast layer, and sponge layer. The amnion has the functions of promoting epithelial repair, inhibiting scar formation, inhibiting cornea neovascularization, inhibiting immunoreaction and the like, so that the amnion covering operation and the amnion transplantation operation are widely applied to treating ocular surface diseases and obtain good clinical curative effect. However, the means for fixing the amnion in the amnion covering operation which is clinically applied at present is mainly surgical suture, which inevitably traumatizes the ocular surface, and because the amnion is thin and is easy to break and perforate, multiple operations are often needed to achieve the treatment purpose.

The applicant's prior application, "cn201620957026. x," amnioscope "," CN201610740372.7, "amnioscope and preservation method thereof," has disclosed a device for fixing an amniotic membrane to an eyelid and a preservation method of the amniotic membrane without an operation, and the amnioscopes disclosed in the two patents have various advantages that a doctor can conveniently operate, a patient has no pain when wearing the amnioscope, and the amnioscope can be replaced at any time according to the dissolution condition and recovery condition of the amniotic membrane of the patient. However, the amniocentoscope still has some problems in practical use, because the amniocentoscope in the application is a medical apparatus and needs to be worn for a long time in the treatment process, the wearing time is usually between two weeks and four weeks, the amniocentoscope cannot be always kept at the same position for such a long time, and especially when the eyeball rotates, especially greatly rotates, the amniocentoscope may have position slippage and dislocation (during the treatment process, the eyeball of a patient may have unconscious large-amplitude rotation, and during the whole treatment process, the eyeball has relatively frequent large-amplitude rotation). The shift of the amnioscope does not affect the treatment effect if the ocular surface injury is near the cornea, but when the ocular surface injury is in the sclera or the far position of the sclera, the shift of the amnioscope may cause the amnion to be unable to cover the wound, and at the moment, a good sanitary environment is needed to allow the doctor to correct the position of the amnioscope again. Therefore, the problem that the amniocentoscope is fixed on the ocular surface for a long time is very necessary.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides a fitting type amniocentesis lens, which can be tightly attached to the ocular surface and can move along with the movement of an eyeball when the amniocentesis lens is worn for a long time, so that the amniocentesis on the amniocentesis lens is always positioned at a treatment position, and the problem of amniocentesis caused by the fact that the amniocentesis lens cannot move along with the eyeball in the past is solved.

In order to solve the technical problem, the invention is solved by the following technical scheme: the utility model provides a laminating formula amniocentesis mirror, includes annular laminating portion, the amnion is fixed laminating portion on, laminating portion lower surface paste and lean on the ocular surface, laminating portion pastes and moves with the eyeball when pasting at the ocular surface.

Preferably, in the above technical scheme, a cross section from the inner circular edge to the outer circular edge of the attaching portion is arc-shaped and is adapted to the radian of the eye surface, and the curvature radius of the attaching portion is smaller than or equal to that of the sclera.

Preferably, in the above technical scheme, the attaching portion is made of a soft material and is deformed under stress.

Preferably, in the above technical solution, the attaching portion has a notch.

Preferably, in the above technical solution, the amnion is fixed to the upper surface of the attaching portion, the lower surface of the attaching portion, or the inner circular sidewall of the attaching portion.

Preferably, in the above technical scheme, the amnion is fixed by tissue glue.

Preferably, in the above technical solution, the attaching portion is made of silicone hydrogel.

In the above technical solution, preferably, the attaching portion is an upper layer and a lower layer, and the amnion is fixed between the upper layer and the lower layer.

Preferably, in the technical scheme, the upper layer is made of a hard material and does not deform under stress; the lower layer is made of soft materials and deforms under stress.

Preferably, in the above aspect, the inner circle portion of the attaching portion may completely expose the cornea.

The principle of the contact lens attached to the eyeball is that the curvature radius of the lens is smaller than that of the cornea, the lens is attached to the cornea and is fixed, and meanwhile, the surface tension of liquid between the lens and the cornea is used for further fixing. Because the amniocentoscope in the application needs to completely expose the cornea, because the curvature radius of the joint part is smaller than or equal to that of the sclera, the joint part is fixedly attached to the sclera, and the closer the curvature radius of the joint part and the curvature radius of the sclera are, the better the joint part and the sclera are. Because the amniocentoscope external diameter in this application will be bigger than conventional contact lens, its fixed eyelid down that leans on entirely, and laminating portion mainly plays fixed spacing effect, again because all need carry out the dropping liquid treatment to the eye many times basically every day in the treatment process of this application amniocentoscope, can deposit the liquid that can be sufficient between laminating portion and the sclera and lubricate.

The amniocentoscope in the application needs to be worn for a long time, and the air permeability of the joint part is very important, so that the important material for manufacturing the joint part in the application is silicon hydrogel or other known high-air permeability non-toxic materials. Because the fitting part can be regarded as tightly attached to the ocular surface, the fitting part needs to be provided with a gap to drain the inner diameter ocular surface area and remove pus generated in the inner diameter ocular surface area, which is very important in the early stage of wearing. In order to reduce the long-time compression of the attaching portion on the sclera, the attaching portion not only needs to have a curvature radius as close as possible to that of the sclera, but also needs to have a soft material on the contact surface between the attaching portion and the sclera.

The deformation is not deformed when the stress in this application means that normal adult presses hard, when gripping, laminating portion upper strata is indeformable or only for the deformation that the unaided eye can't perceive. The forced deformation in the present application means that the fit portion or the lower layer of the fit portion is significantly deformed when pressed by a normal adult.

Compared with the prior art, the amniotic membrane forceps can be tightly attached to the ocular surface and move along with the movement of the eyeball when the amniotic membrane forceps are worn for a long time, the amniotic membrane on the amniotic membrane forceps is always positioned at the treatment position, and the problem of amniotic membrane forceps offset caused by the fact that the amniotic membrane forceps cannot move along with the eyeball in the past is solved.
