INJECTOR FOR EYE
First Claim
1. An injector for an eye for inserting a graft into an eyeball, comprising:
- an outer cylinder and a graft holding structure arranged inside the outer cylinder to be slidable with respect to the outer cylinder, the graft holding structure including a graft holding part capable of being stored inside the outer cylinder, the graft holding part forming a space capable of storing a graft between an inner surface of the outer cylinder and the graft holding part at the time of the graft holding part being stored in the outer cylinder, and the graft holding part protruding from the outer cylinder at the time of the graft holding structure being advanced and the graft being able to be taken out from the outer cylinder.

Abstract
[PROBLEMS] To provide an injector for ophthalmology which can guide an implant easily to an transplant place without causing any damage to the implant when the implant is inserted into an eyeball. [MEANS FOR SOLVING PROBLEMS] The injector for an eye used for inserting an implant into an eyeball comprises an outer tube, and an implant holding structure arranged in the outer tube to be slidable with respect to the outer tube. The implant holding structure has an implant holding portion which can be contained in the outer tube and forms a space for containing the implant between the implant holding portion and the inner surface of the outer tube when it is contained in the outer tube. The implant holding portion projects from the outer tube when the implant holding structure is advanced and the implant can be taken out from the outer tube.

18. A method for inserting a graft into an eyeball by using an injector for an eye including an outer cylinder and a graft holding structure arranged inside the outer cylinder to be slidable with respect to the outer cylinder, comprising the steps of:
- inserting the outer cylinder into an eyeball with a graft stored between a graft holding part of the graft holding structure stored in the outer cylinder and an inner surface of the outer cylinder, and advancing the graft holding structure with respect to the outer cylinder to take out the graft held on the graft holding part form the outer cylinder.

19. A method for inserting a graft into an eyeball by using an injector for an eye including an outer cylinder and a graft holding structure arranged inside the outer cylinder to be slidable with respect to the outer cylinder, and the graft holding structure further including a middle cylinder and an inner cylinder arranged inside the middle cylinder to be slidable with respect to the middle cylinder, comprising the steps of:
- inserting the outer cylinder into an eyeball with the graft stored between the graft holding part of the inner cylinder stored in the outer cylinder and the inner surface of the outer cylinder, advancing the inner cylinder and the middle cylinder included in the graft holding structure with respect to the outer cylinder to arrange at least a leading end of the inner cylinder further toward the distal end than the leading end of the outer cylinder, and advancing the middle cylinder with respect to the inner cylinder to push out the graft held on the graft holding part of the inner cylinder from the outer cylinder.
