Embodiment Construction

[0051] as in figure 1 As can be seen in , the injection device shown comprises a tubular body 1 with a housing 2 surrounding an axial cavity, in which a plunger 3 can slide in an axial direction 4 . A plunger 3 is inserted into the axial cavity at the proximal end 5 of the tubular body 1 . A cylinder 7 is arranged at the distal end 6 of the tubular body, the cylinder having an exit cavity communicating with the axial cavity of the tubular body 1 . This exit chamber has a cross-section that decreases in the opposite direction to the tubular body and opens outwards at the free end of the cylinder 7 .

[0052] The injection device shown also comprises a housing 8 in the axial cavity of the tubular body 1 for housing a storage shuttle 9 containing a flexible intraocular lens 10 (see figure 2 ).

[0053] According to the present invention, if figure 1 As shown in , the casing 2 of the tubular body 1 has a side opening allowing access to the housing 8 from the outside. The sto...

Abstract

A device for injecting a flexible intraocular lens, comprising a tubular body (1) that has a casing (2), a plunger (3), a barrel (7) having a cross-section that decreases in the opposite direction tothe tubular body, and a housing (8) in the axial cavity of the tubular body intended to receive a storage shuttle (9) containing a flexible intraocular lens (10), the casing (2) of the tubular body having a side opening, so as to allow the insertion of the storage shuttle (9) and, next to said side opening, the above-mentioned casing (2) carrying a first outwardly-protruding rotary attachment means (11) capable of engaging with a second rotary attachment means (12) provided on the storage shuttle (9), such that, when the two above-mentioned rotary attachment means are engaged, the storage shuttle is able to rotate about an axis of rotation parallel to said axial direction (4) of the axial cavity of the tubular body.

Description

technical field [0001] The present invention relates to a flexible intraocular lens injection device (or an injection device for a flexible intraocular lens, or a device for injecting a flexible intraocular lens), comprising: [0002] - a tubular body with a housing and an axial cavity and proximal and distal ends; [0003] - a plunger inserted into said axial cavity at said proximal end and movable in said cavity in axial direction; [0004] - a barrel arranged at said distal end of the tubular body and having an exit cavity communicating with the axial cavity of the tubular body, the exit cavity having a cross-section that decreases in the opposite direction to the tubular body; and [0005] - Housing located in the axial cavity of the tubular body for housing the storage shuttle containing the flexible intraocular lens. Background technique [0006] Intraocular lenses (IOLs) are intended to replace the opaque lens (natural lens) of the eye in patients with cataracts dur...
