摘要:
System for introducing corneal implants, said system comprising: a deformation chamber (202) having a proximal end, a distal end and a pair of semicircular halves (204) articulated together along a common side, each half having semicircular an inwardly oriented arcuate surface (212) along an opposite side, said surfaces being adapted to evert the opposite edges of an implant (C) having an outer surface and an inner surface when said implant is placed between the surfaces of the chamber deformation chamber as the halves are closed; a hollow element (120) having a proximal end and a distal end configured for insertion in a corneal pocket (140) or for advancing in an incision in the cornea or sclera for insertion in the anterior chamber and having a axial hollow passage (126) that narrows in the distal direction, in which the axial hollow passage is attached to a distal end of the deformation chamber, receives the implant in an arcuate configuration and includes an inwardly oriented arcuate surface that prevents additionally the opposite edges of the corneal implant radially inwards as the insert is advanced axially through the passage, in which the arcuate surfaces oriented inwardly of the hollow element are arranged on opposite sides of a projection (210) which extends axially through the hollow passage to form inwardly directed ramps to wind the opposite edges of the implant into a C-shaped, in which The opposite edges are avoided, but do not touch the inner surface of the implant as the implant advances; and an axial pusher (230) arranged to be advanced through the deformation chamber and in the axial hollow passage of the hollow element to engage and axially advance a constricted cornea implant through the hollow passage.Sistema para introducir implantes de córnea, comprendiendo dicho sistema: una cámara de deformación (202) que tiene un extremo proximal, un extremo distal y un par de mitades semicirculares (204) articuladas entre sí a lo largo de un lado común, t
