Description
Technical field
The utility model relates to field of biomedicine technology, more particularly to a kind of ocular dressing bracket component.
Background technique
A variety of eye surface diseases such as ocular surface alkali burns, ulcer of the cornea can cause the damage or missing of cornea, conjunctiva, and normal companion
There is the formation of cornea rebirth blood vessel, and then influences visual performance.Currently, being used for repairing for Ocular surface damage there are many biomembrane
It is multiple, wherein most importantly amnion.
Amnion (amniotic membrane, AM) differentiation has from trophocyte and promotes epithelialization, inhibits fibrosis, suppression
The biological characteristics such as inflammation processed.Idicatio of the amnion operation at present in terms of the conjunctival reconstruction of angle has chemical injury, thermal burn, cornea to burst
Ulcer, limbal stem cell deficiency (limbal stem cell deficiency, LSCD), atretoblepharia, pteryium etc..And
Corneal neovascularization is caused by many factors such as inflammation of eye section, wound, infection, malnutritions.Can significantly it be subtracted using amnion
The generation of few cornea rebirth blood vessel, and inhibiting effect played to the migration of vascular endothelial cell, growth, thus amnion operation for
Corneal neovascularization and a variety of eye surface diseases have therapeutic potential.
Tradition covers in art amnion and mainly takes sewing method to the fixation of amnion.But suture is fixed time-consuming general
All over growing partially, amnion is easily crushed in operation, and the amnion of suture is easy to fall off, and knot itself is also big to the stimulation of ocular, is aggravated
Patient postoperative discomfort.In addition melt within amnion general 7~10 days, usually also need to carry out Repeated Operation, increase wound, cause
Patient suffering.
Art is covered just because of amnion, and operation time-consuming relatively too long, suture stimulation ocular, amnion are made using sewing method
Thin and frangible, amnion needs repeat surgery after melting, a series of inherent shortcomings such as keep area coverage limited are limited by exposure range, promotees
The research of Sutureless fixed form is made.
Have at present raw using ocular made of polymethyl methacrylate (polymethylmethacrylate, PMMA)
Amnion is fixed in the fixed device of object film, which is a fixed ring, and ring is interior equipped with groove, and with
A fracture is stayed in order to the hematocele hydrops being discharged under amnion in the lowest point of arched roof.It is completed using the Ocular biomembrane-fixed equipment
Full conjunctival sac amnion covering operation, overcomes the defect of suture fixation, but the early stage for being mainly used in chemically Ocular surface burns is controlled
It treats.Unfortunately, though the Ocular biomembrane-fixed equipment has ocular radian, since PMMA is hard and size is fixed, very
Hardly possible matches the conjunctival sac of different patients, and comfort is poor.
In addition, Bio-Tissue company also develop it is a kind of bicyclic embedded with the polycarbonate concavity for freezing amnion
(ProKera), the effect of contact lense can be similar to.But due to being limited by shape and size, ProKera is equally existed ProKera
The lesser problem of area coverage in traditional covering operation, control effect it is low, and be difficult to severe ocular surface burn the large area surface of a wound it is helpful,
And it needs to change inflexible when amnion.
