Orthopedic surgical device and orthopedic surgical robot system

An orthopedic surgical device for operating an orthopedic surgical tool, comprising:

• two movable mechanisms respectively providing the orthopedic surgical tool with reciprocating motion variables in different directions from a horizontal direction, a depth direction, and a vertical direction;
• a decoupling mechanism;
• and
• a clamper for clamping the orthopedic surgical tool;
• wherein each of the two movable mechanisms comprises:
• a base, and a linear motor, a movable platform and a linear guide or a cross-roller guide, all of which are mounted on the base;
• the linear motor comprises a stator and a mover;
• the mover drives a corresponding movable platform to slide along the linear guide or the cross-roller guide, where the linear guide is provided with a sliding block, and the mover is connected to the sliding block;
• the mover is connected to the corresponding movable platform for driving the movable platform to perform a reciprocating motion;
• the corresponding movable platform is connected with the decoupling mechanism for taking the decoupling mechanism to perform a corresponding reciprocating motion together;
• the decoupling mechanism comprises:
• a mounting seat and a decoupling connecting seat connected with the mounting seat in a relatively movable manner;
• the clamper is installed to the mounting seat to hold the orthopedic surgical tool to the decoupling mechanism;
• the mounting seat and the decoupling connecting seat are respectively connected to the respective movable platforms of the two movable mechanisms, whereby one movable mechanism drives the decoupling mechanism moving by means that the corresponding movable platform takes the mounting seat of the decoupling mechanism to perform a corresponding reciprocating motion together, and the other movable mechanism drives the decoupling mechanism moving by means that the corresponding movable platform takes the decoupling connecting seat of the decoupling mechanism to perform a corresponding reciprocating motion together;
• thereby, the two movable mechanisms cooperate to enable the decoupling mechanism take the orthopedic surgical tool held by the clamper to a predetermined position within a motion range thereof;
• each of the two movable mechanism also comprises a limit switch and limit blocks;
• the limit switch is installed on the base, and the limit blocks are arranged at both ends of the corresponding movable platform and cooperate with the corresponding limit switch for limiting a motion position of the corresponding movable platform;
• each of the two movable mechanisms further comprises a grating ruler and a reading head, the grating ruler is arranged along a motion route of the corresponding movable platform, position information is obtained by the reading head, and the grating ruler and the reading head cooperate with each other to detect a position of the corresponding movable platform, the clamping mechanism is connected to the decoupling mechanism;
• the decoupling mechanism is connected to the two movable mechanisms;
• and the two movable mechanisms cooperate to—enable the orthopedic surgical tool to reach any position within a motion range.
