Retinal vascular bypass surgery (RVBS) is a kind of complicated operation, with high precision and dexterous manipulation limited to small workspace. It is necessary to design a robot-assisted manipulator for performing such a task. The process of RVBS is described according to clinic operation at first. The motion of surgeon and workspace of surgical instruments are analyzed; correspondingly, motions of robot-assisted manipulator are obtained. Then, mechanism of manipulator including remote center of motion (RCM) is proposed through considering constraints induced by pierce points of sclera. Finally, inverse kinematics of the proposed robot-assisted manipulator is done to realize retinal surface motion. The analysis results show the end-effectors of robot-assisted manipulator can reach arbitrary position on the retinal surface.

Diffuse dermal angiomatosis (DDA) is a benign, acquired, reactive vascular proliferation. DDA is clinically characterized by painful purpuric plaque with central ulceration. The histopathologic hallmark is diffuse proliferation of endothelial cells that are arranged interstitially between collagen bundles of the reticular dermis. DDA has been reported in association with peripheral atherosclerotic disease, arteriovenous fistula and heavy smoking. We report the case of a 49-year-old Asian male with DDA who presented with a painful stellate-shaped purpuric patch on the right thigh. Histopathologic examination showed proliferation of CD34-positive spindle cells in the dermis. Our patient underwent vascular bypass surgery along with tight control of cardiovascular risk factors, which yielded successful results.
