Abstract

The present invention discloses a robotic assisted system for ophthalmic surgery, comprising a first driving unit, a second driving unit and a third driving unit, wherein the three driving units can respectively complete the movement in three dimensions, the first driving unit is connected with the second driving unit, the second driving unit is connected with the third driving unit, and an instrument is arranged on the third driving unit; during operating, the third driving unit can drive the instrument assembly to move, the second driving unit can drive the third driving unit and instruments thereon to move, and the first driving unit can drive the second driving unit, the third driving unit on the second driving unit and the instruments on the third driving unit to move; the accurate control on the instruments can be completed by controlling the three different driving units. Through the specific RCM structure, the advantages of high precision and compact structure are achieved, and the present invention is suitable for various eye surgeries such as retinal bypass surgery, sub-retina injection and vitrectomy. The ophthalmic surgical device of the present invention has extremely high safety.
