Background technique
China is as the maximum glaucoma illness country in the whole world, and wherein angle-closure glaucoma accounts for main Types (about 3,500,000
People), and it is common with chronic angle closure glaucoma patient.Goniosynechia separating operation obtains domestic and international extensive concern in recent years,
It is considered as the effective Minimally Invasive Surgery mode for solving chronic angle closure glaucoma.
The country there is no special goniosynechia separation instrument at present, clinically mainly use intraocular iris repositor, view
Film tweezer, super newborn dust collecter or syringe needle carry out the separation of adhesion.It is designed since these instruments are not goniosynechia separation,
In separative efficiency, separation precision and minimal invasive all Shortcomings.It is separated using above-mentioned instrument or is not easy completely to divide
From goniosynechia or cause the negative damage of surrounding tissue (iris, girder).Eventually lead to separation not exclusively, or isolated room
Angle is easy adhesion or damaging surrounding tissue intraocular hypertension again, is unable to reach the purpose stablized and intraocular pressure is effectively reduced.In the world
On, the goniosynechia separation instrument of Japanese INAMI company design closes that the top of the horn is sharp, and separative efficiency is not high and is easy to injure neighbouring
Trabecular tissue.With deepening continuously to the cognition that goniosynechia separates, the clinical demand of effective room rate adherence Separation device is got over
Come more urgent.Therefore, it is necessary to a goniosynechia separators, can meet separative efficiency height, and not room around easy damaged simultaneously
Corner structure (iris, girder etc.).
