Summary of the invention
The purpose of this utility model just provides a kind of retina implantation device easy to use, accurate, it can not only be in grafting device fixing holostrome retinal tissue graft firmly, and can make things convenient for, direction and speed when accurately control is transplanted, reduce the difficulty of transplanting, improve the effect of transplanting.
The purpose of this utility model is achieved through the following technical solutions: promptly a kind of retina implantation device, it is characterized in that: it comprises lever and fixing tube head, wherein, be provided with passage in the lever, the front end of lever is connected with the fixing head of band through hole, fixedly tube head is connected with lever by fixing head, fixedly tube head comprises fixing interior pipe and the fixedly outer tube that tightly is enclosed within its surface, and fixedly the length of outer tube is greater than the length of pipe in fixing, make fixedly formation graft lock chamber between the inner spout and the fixing outer mouth of pipe, crooked transplantation head is enclosed within fixedly on the outer tube and with fixing interior pipe and communicates, its front portion is 105 °～140 ° angle bending, and hydraulic tube penetrates operating grip and communicates with fixing interior pipe on the fixing tube head.
Owing to adopted technique scheme, the utlity model has easy to use, accurate advantage, it can not only be in grafting device fixing holostrome retinal tissue graft firmly, and can make things convenient for, direction and speed when accurately control is transplanted, obviously reduce the transplanting difficulty, significantly improved transplantation effect.
