Abstract: An active variable stiffness clamping device for pelvic fracture reduction robot, belonging to the technical field of medical robots. The clamping device includes an affected side adjusting support module and a healthy side fixing module which are in fit with each other. The affected side adjusting support module is provided with a pair of electric pin rod connector modules connected to the affected side adjusting support module. The healthy side fixing module includes a healthy side bed clamp seat, the healthy side bed clamp seat is provided with a healthy side support rod, the healthy side support rod is provided with a healthy side spherical hinge base, and the healthy side spherical hinge base is provided with a pair of healthy side fixers which are in clearance fit with each other.

Abstract: A clamping instrument for a robot for pelvic fracture reduction is provided. The clamping instrument comprises an affected-side main frame module, an affected-side secondary frame module, an affected-side lower frame module, a docking module, a bone spike clamp holder and an unaffected-side fixing mount module. The affected-side main frame module is configured for fixing bone spikes at the anterior superior iliac spine of the pelvis, the affected-side secondary frame module is configured for fixing bone spikes at the anterior inferior iliac spine of the pelvis, and the affected-side lower frame module is configured for fixing bone spikes at the ilium of the pelvis; the docking module is configured for quickly connecting the clamping instrument with the surgical robot; the unaffected-side fixing mount module is configured for fixing bone spikes disposed in the pelvis on the unaffected side; and the bone spike clamp holder is configured for clamping bone spikes.

Abstract: The present disclosure relates to a universal and liquid expansion type clamping device for a pelvic fracture reduction robot. The clamping device is composed of an affected side spherical hinge support module, a pin rod clamping part, a rod-rod clamping part, a butt joint module, and a healthy side fixing module. The affected side spherical hinge support module is a main module for the pelvis clamping device, and by adopting a spherical hinge structure, the affected side spherical hinge support module is connected to the pin rod clamping part and the butt joint module respectively. The rod-rod clamping part is fixedly installed on one side of an operation table by the healthy side fixing module.
