Abstract：Objective To develop the novel intraocular light source holding mechanism utilizing a flexible arm structure.Methods A new intraocular light source holding mechanism was designed and constructed,comprising I-shaped frame and flexible arm intraocular light source.The I-shaped frame could be hard connected to the flexible arm and played a fixed role.Flexible arm,terminal flared head,four-hole segmented joint and intraocular light source jointly constituted the flexible arm intraocular light source,which was actuated by a cable-driven mechanism consisting of 4 mi-crofilaments and 2 threaded knobs.By analyzing the geometric relationship of different parts of the flexible arm,the driv-ing and kinematic models of the flexible arm were constructed.Results A novel intraocular light source holding mecha-nism was designed based on the flexible arm structure,the driving and kinematic model of the flexible arm was construc-ted and verified,which could realize the function of intraocular surgery illumination.Conclusion A new type of intraocu-lar light source holding mechanism based on flexible arm structure can replace the traditional intraocular light source,which is expected to solve the problem of intraocular light source control in ophthalmic robotic surgery.
