The invention relates to the technical field of arthroscopic surgery instruments, in particular to a support for a sports medicine arthroscopic surgery, which comprises a support, a lifting platform and a leg fixing mechanism, and the lifting platform locks the height position of the leg fixing mechanism on the support through a limiting bolt; the leg fixing mechanism comprises a fixed frame fixedly connected with the lifting table and a movable frame hinged through a rotating connector. The pull rope is wound around the guide wheel in the sliding rail box to be connected with the shank binding belt, and when the knee joint bends and stretches, the second spring pushes the sliding block to move in a self-adaptive mode; during knee bending, the spring extends to compensate looseness of the pull rope; when the knees stretch, the springs are compressed to absorb redundant tension. The tensile force is always perpendicular to the shank axis through mechanical decomposition, and lateral shearing force is eliminated. A spring dynamic compensation mechanism maintains constant upward effective component force, pulling force direction deviation caused by a traditional fixed fulcrum is avoided, unexpected internal rotation during shank lifting is fundamentally restrained, and knee joint ligaments are protected against abnormal stress damage.

A system including a knee ranging tool: including a base configured to locate on a resected proximal face of a tibia in a knee of a patient; defining a tibial reference surface configured to run against a femoral surface of an artificial femoral component, installed on a distal face of a femur of the patient, during articulation of the knee of patient; including a set of stages interposed between the base and the tibial reference surface, configured to locate the tibial reference surface relative to the base, and compliant to medial-lateral translation, anteroposterior translation, and transverse rotation; and configured to indicate a medial-lateral translation offset, an anteroposterior translation offset, and a transverse rotation offset corresponding to a position of the tibial reference surface, relative to the base, that yields elastic deformation of ligaments in the knee over a range of motion of the knee.

The utility model discloses a knee joint ligament nursing training device relates to the technical field of rehabilitation auxiliary equipment, including support platform, first training mechanism, second training mechanism, and the top surface both ends of support platform all are installed with handrails, the both sides of support platform all are seted up with the installation mouth, the both sides of installation mouth all are seted up with the fixed hole, first training mechanism, second training mechanism all install in the installation mouth, the utility model discloses the setting of first training mechanism, second training mechanism can carry out the training of different projects to two patients in the same time, promotes the training efficiency under the coincidence time, reduces the waiting time, makes the functionality of overall device stronger, is more in line with the actual training use.

The utility model relates to the technical field of intelligent health protection, in particular to a wearable equipment control system for knee joint injury detection and pre-protection, which comprises a controller, an upper computer, a data transmission module, a signal acquisition module, a wearable module and an electrical stimulation module, and is characterized in that the controller controls the wearable module; the upper computer records, checks and modifies personal information and checks the electric quantity of the wearable module; the data transmission module is used for communication between the controller and an upper computer; the signal acquisition module acquires human knee joint movement conditions; the electrical stimulation module is used for stimulating a human muscle system, the system collects knee joint movement conditions in the movement process in real time through the wearable module, judges whether injury risks exist or not based on a knee joint injury early warning algorithm of a deep learning model, and if the injury risks exceed an injury risk threshold value, gives an alarm. If yes, the electrical stimulation module can automatically apply electrical stimulation to the corresponding muscle position, muscle groups are promoted to contract, knee joint restoration is helped, and knee joint ligament injury is monitored and prevented.

The invention provides a bone tunnel positioning method for knee joint ligament reconstruction surgery. The bone tunnel positioning method for knee joint ligament reconstruction operation comprises the following steps: acquiring a joint medical image of a knee joint; constructing a virtual coordinate system according to the joint medical image; wherein the virtual coordinate system comprises a rectangular bounding box constructed based on a Blumensaat line, the lower edge of the thighbone outer side condylar joint cartilage, the front edge of the intercondylar fossa and the posterior cortical edge; dividing a plurality of quadrants in the rectangular bounding box, and performing bone tunnel key point detection in a target quadrant in the plurality of quadrants to obtain a bone tunnel key point detection result; and generating a knee joint ligament reconstruction planning scheme according to a bone tunnel key point detection result.

A garment of the present invention comprises a closed tensionable loop for stabilizing a human knee. The loop is arranged to freely move along a conduit within the garment and is provided with a tensioner. The conduit crosses over itself between the lateral and a medial side on the anterior of the leg at least one of above and below the knee to provide compression on the ligaments of the knee when the loop is tensioned. The conduit circles the lower leg at a distal region of the triceps surae, thereby providing an anchor to the lower leg. An anchor is provided at or above the thigh. A method for stabilizing the knee using the tensionable loop involves positioning the garment so as to ensure that the conduit follows a predetermined path on the leg that places the loop over at least one of the two collateral ligaments of the knee and the tensioner is operated to adjust the compression on the ligaments.
