The invention provides a leg lower supporting structure of an off-road vehicle type, a front bumper beam assembly and a vehicle. The leg lower supporting structure comprises a first supporting plate and a second supporting plate, the second supporting plate is fixedly connected with the first surface of the first supporting plate and divides the first supporting plate into a first supporting part and a second supporting part which are located on the two opposite sides of the first supporting plate, the first supporting part is used for being connected with the bottom of the front bumper beam, and the second supporting plate is used for being connected with the side portion of the front bumper beam; the first reinforcing ribs are fixedly connected with the first supporting part, and each first reinforcing rib extends in the direction of the connecting line of the first supporting part and the second supporting part. After the leg lower supporting structure is installed on the front bumper beam, in the collision process of the aPLI leg type and a vehicle, the leg lower supporting structure is bent downwards, the knee and the shank are supported and buffered, investigation indexes such as knee ligament elongation and shank bending moment of the aPLI leg type are reduced, and the reliability of the aPLI leg type is improved. The defects that a large off-road vehicle is tall, large in approach angle and free of a supporting shank structure are overcome.

The application discloses a leg nursing bracket for bone surgery and relates to the technical field of medical devices, which comprises a supporting rod and a stabilizing mechanism, wherein the stabilizing mechanism comprises a connecting frame, one end of the connecting frame is slidably connected with a sliding block, a locking unit is arranged on the sliding block, a supporting assembly is mounted on one side of the sliding block and the end of the connecting frame away from the sliding block, the supporting assembly comprises a supporting plate, the supporting plate is rotationally connected with the connecting frame and the sliding block through a rotating shaft, and an end cover is fixed to the end of the rotating shaft, the two angle-adjustable supporting plates are used for supporting and lifting the thighs and the shanks respectively, the height of the supporting plate for lifting the shank is adjustable, thus the two supporting plates can support and lift the legs according to the positions and angles of the thighs and the shanks respectively, the knee joint movement is limited, the healing effect after the knee ligament surgery is ensured, and in addition, the stabilizing mechanism is designed as a wearable type, can be worn on the legs when the patient gets out of bed and continuously maintains the flexion degree of the legs.

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 knee joint ligament positioner comprises a first cross beam and a second cross beam which are arranged on two planes perpendicular to each other, the first cross beam and the second cross beam are each of an arc-shaped structure, and the second cross beam can slide along the first cross beam and is fixed to the middle of the first cross beam through a first locking structure; the first positioning pipe is arranged on the first cross beam in a sliding mode, the second positioning pipe is arranged on the second cross beam in a sliding mode, the positioning hook is fixed to the first end of the first cross beam, and the sleeve is arranged at the second end of the first cross beam in a sliding mode and used for fixing a threading device or a hollow drill. And the positioning hook, the first positioning pipe, the second positioning pipe and the sleeve all point to a sphere center formed by the first cross beam and the second cross beam. The method has the advantages that two-dimensional positioning is achieved, and positioning and follow-up surgical operation are facilitated.

The invention provides an integrated whole-body musculoskeletal model based on OpenSim, a construction method and application. The method comprises the following steps: integrating a knee joint ligament and a contact structure into a musculoskeletal model containing complete muscles of a trunk and lower limbs to obtain a musculoskeletal model containing the knee joint ligament and the contact structure; and then model adjustment is carried out to obtain an integrated whole-body musculoskeletal model. The integrated whole-body musculoskeletal model can be used for predicting the load response of the anterior cruciate ligament. When a knee joint ligament structure is added, an algorithm and a program for automatically searching grid nodes at ligament and muscle insertion points are designed, so that the knee joint ligaments and muscles can be automatically adjusted and accurately positioned and inserted into a musculoskeletal model containing complete muscles of a trunk and lower limbs; the muscle and the knee joint ligament can be accurately attached to the surface of the skeleton, and accurate integration of the knee joint ligament and the lower limb muscle is achieved.
