  • Endodontic robotic surgical system and endodontic robotic surgical assembly
    Patent number: 12029509
    Abstract: An endodontic robotic surgical system is provided. The endodontic robotic surgical system includes a robot arm and an endodontic robotic surgical assembly electrically connected to the robot arm. The endodontic robotic surgical assembly includes a multiple-axis force sensing device, a treatment assembly and an assistive device. The treatment assembly includes a housing, a drawstring-positioning structure disposed on the housing, a plurality of drawstrings connected to the drawstring-positioning structure, and an endodontic surgical element fitted to the housing. The drawstring-positioning structure is electrically connected to the multiple-axis force sensing device. The assistive device is adapted to be put on a tooth structure in a human oral cavity. The drawstrings are connected to different points on the assistive device. An endodontic robotic surgical assembly is further provided.
