Abstract: A robot navigation system includes a handheld robot, a spatial information measuring device, a computing module and a display. The hand-held robot has a body, a tool and a movable connection mechanism. The movable connection mechanism is connected between the body and the tool, so that the tool can move relative to the body. The spatial information measuring device is configured to track the body, the tool and a target. The computing module is connected to the spatial information measuring device to obtain a plurality of relative positions between the body, the tool and the movable connection mechanism with respect to the target. The computing module calculates a guiding region according to the relative positions and mechanical parameters of the handheld robot. The display is configured to display the guiding region and the handheld robot based on the coordinate of the target.

Abstract: The present invention provides a handheld robot for orthopedic surgery and a control method thereof. The handheld robot of the present invention includes a main body, a grip, a kinematic mechanism, a tool connector, a tool, a force sensor and a positioning unit. The handheld robot of the present invention combines the position/orientation information of the tool acquired by the positioning unit with the force/torque information acquired by the force sensor, and utilizes the combined information to adjust the position of the tool so as to keep the tool within the range/path of a predetermined operation plan. In this way, the precision of the orthopedic surgery can be enhanced, and the error occurred during the surgery can be minimized.

Abstract: The present disclosure generally relates to the drilling control system and the drilling control method for surgical applications. The drilling control system may comprise a drilling device, a spatial sensor system and a control unit. The control unit may receive and store biomechanical information, mechanical information and spatial information to generate drilling information and control output, and calculate a discrepancy index according to the biomechanical information and the drilling information. The discrepancy index is calculated according to cross correlation of a slope of the biomechanical information and a slope of the drilling information. With the present disclosure, the accuracy and safety of drilling process is greatly improved.

Abstract: An handheld accessory system for an ultrasonic equipment and an inspection method applicable to the accessory system. The accessory system includes a force detector and a positioning device attached to a hand-held ultrasonic probe, and a signal processing device. A user may apply the ultrasonic probe to the target tumor with a certain compression depth. A force compensation module in the signal processing device allows to make compensation due to unsteady compression depth, thereby providing for the operation of transverse palpation to detect the stiffness ratio and mobility of a target relative to its surrounding tissues, and being therefore specifically suitable for diagnosing breast tumors, as benign or malignant.
