Abstract
Vein of the retina being closed is called retinal vein occlusion. As a new treatment for retinal vein occlusion, microcannulation has been used in eye surgery. Microcannulation is a treatment to approach the fundus by inserting a micropipette from the surface of the eye, injecting directly thrombolytic drugs to the retinal vein being occluded. Because microcannulation is very difficult surgery even for the experienced doctors, robotic system for vitretinal surgery has been developed. However, evaluation and training system is not well developed. Therefore, we propose the microvessel model with a circular cross-section and a curved surface structure for evaluation of some microsurgical robotic systems to assistant vitreoretinal surgery and training for doctors.
