Abstract: The provided is a medical robot, including single-arm mechanism, which including pitching adjusting mechanism and deflection adjusting mechanism. One end of telescopic pull rod of pitching adjusting mechanism is hinged to one end of hinge portion, other end connects to pitching motor; other end of hinge portion hinges to one end of main rotating shaft to be driven by pitching motor to slide telescopically relative to main rotating shaft to implement pitching movement of hinge portion. First gear of deflection adjusting mechanism meshes with second gear and sleeves outer wall of main rotating shaft, main rotating motor drives first gear by second gear, to drive main rotating shaft to rotate, such that deflection adjusting mechanism implements deflection movement of pitching frame by means of transmission of main rotating shaft of pitching adjusting mechanism. The further provided are surgical auxillary positioning system and control method.

Abstract: Puncture positioning system includes planning module, ultrasound module, workstation module, display module, adjustment module and execution module.

Abstract: The present disclosure provides an operation method for bone tissue.

Abstract: Provided are a tunnel position determination system and method for anterior/posterior cruciate ligament reconstruction, which relate to the technical field of ligament reconstruction. The system includes: a coordinate system establishment module for establishing a femoral coordinate system and a tibial coordinate system; a feature point selection module for selecting femoral feature points and tibial feature points; and a tunnel position determination module for determining a femoral point and a tibial point during reconstruction on the basis of the femoral feature points and the tibial feature points, and determining a specific tunnel position of an anterior or posterior cruciate ligament reconstruction tunnel by means of the femoral point and the tibial point. The present disclosure provides a method for selecting the femoral point and the tibial point during tunnel reconstruction, such that a specific path of a formed reconstruction tunnel is more accurate.

Abstract: Provided is a positioning system for posteromedial structure, posterolateral structure and medial patellofemoral ligament reconstruction, which relates to the technical field of ligament reconstruction.

Abstract: A joint movement analysis system, comprising: a plurality of actual markers positioned around a joint, wherein space positions of the actual markers track space movement of virtual marker points that are set at anatomical bony landmark positions of the joint; an optical tracking device that senses the space positions of the actual markers so as to obtain a space movement data of the actual markers; a data collection device that collects the space movement data of the actual markers and a relative space position data of the virtual marker points with respect to the actual markers; and a data analyzing device that obtains a space movement data of the virtual marker points from the space movement data of the actual markers, and simulates and analyzes a movement of the bony structure of the joint according to the space movement data of the virtual marker points.

Abstract: A knee joint dynamic evaluation method for diagnosing human joint diseases by tracking motions of the knee joint includes constructing an evaluation model including a first angular difference threshold ?1, a second angular difference threshold ?2, and an anterior-posterior displacement difference threshold ?; synchronously collecting a single set of three-dimensional and six-degree-of-freedom movement data of a left knee joint and that of a right knee joint with devices; comparing the three-dimensional and six-degree-of-freedom movement data between the left and right knee joints with a data analyzing device, and calculating differences of the flexion and extension angles, the medial and lateral tilt angles, the medial and lateral rotation angles, and the anterior-posterior displacement movement values of the two sets of movement data; inputting the differences into the evaluation model to obtain the corresponding grading system, which will output the first, second, third, or fourth evaluation level.

Abstract: A joint movement analysis system is provided in the present invention, comprising a calibrating device which is used for setting connections between actual marker points around a joint and virtual marker points at the anatomical bony landmark positions of the joint to track the space movement of the joint; an optical tracking device which is used for sensing the space position of the actual marker points so as to obtain the space movement data of the actual marker points; a data collection device which is used for collecting the space movement data of the actual marker points and the space relative position data of the virtual marker points with respect to the actual marker points; a data analyzing device which is used for obtaining the space movement data of the virtual marker points by optimization operating of the movement data of the actual marker points, and simulating and analyzing the movement condition of the joint bony structure according to the space movement data of the virtual marker points.
