Abstract

An insertion device (100; 100') for inserting a retinal prosthesis (200) into the eye of a patient comprises: a handle portion (1; 1') arranged to be grasped by a user of the insertion device (100; 100'), a cannula element (12; 12') arranged to be inserted into the eye of a patient positioned at a longitudinal end (4A) of the handle portion (1; 1'), a holding portion (3; 3') arranged for holding the retinal prosthesis (200) in the coiled configuration (P), the holding portion (3; 3') being provided with an internal longitudinal hole (24; 24') so dimensioned to house the retinal prosthesis (200) in the coiled configuration (P) and to avoid the retinal prosthesis (200) to uncoil in the insertion device (100; 100'), an actuating mechanism (2, 21; 2', 32') coupled to the handling portion (1; 1') and arranged for being rotated for moving the retinal prosthesis (200) in relation to the cannula element (12; 12') for inserting the retinal prosthesis (200) into the eye (300) of the patient, wherein the insertion device (100; 100') further comprises a conversion mechanism for transforming the rotation movement of the actuating mechanism (2, 21; 2', 32') in a translation movement for moving the retinal prosthesis (200) in relation to the cannula element (12; 12').
