7 results about "Knee orthosis" patented technology

The invention discloses a knee joint orthosis and an orthosis torque quantitative control and data acquisition method, the knee joint orthosis comprises a thigh frame, a shank frame, a thigh bandage, a shank bandage and a hinge connecting the thigh frame and the shank frame, and the knee joint orthosis further comprises an angle quantitative adjusting mechanism and a torque monitoring system. The included angle between the bandage and the horizontal plane can be accurately changed and adjusted by changing the first slot position of the first sliding block part or changing the second slot position of the second sliding block part or simultaneously changing the slot positions of the first sliding block part and the second sliding block part. The change of the geometric parameter directly causes the change of the tension of the bandage, so that the accurate control of the orthopedic torque is realized. The torque monitoring system can monitor and output quantitative data of orthopedic torque in real time, and a complete closed-loop control system is formed. Compared with a traditional device, according to the scheme, the orthopedic torque capable of being quantitatively adjusted is provided, more importantly, a complete monitoring feedback mechanism is established, and the whole mechanical adjusting process is visible, measurable and controllable.

The invention relates to a knee orthosis that introduces a moment into the area of ​​the joint in order to reduce, for example, the increased one-sided load within the joint in the case of X or O leg position.

The utility model relates to the technical field of orthotics, and discloses an elastically-bound knee joint orthotics which comprises a movable disc, the front end of the movable disc is movably connected with an adjusting disc, the top end of the movable disc is fixedly connected with a first supporting rod, the rear end of the first supporting rod is provided with a first supporting plate, and the rear end of the first supporting plate is provided with a second supporting plate. A second supporting rod is fixedly connected to the bottom end of the adjusting disc, a second supporting plate is installed at the rear end of the second supporting rod, protective soft cushions are installed at the rear end of the first supporting plate and the rear end of the second supporting plate, and a connecting frame is installed at the bottom end of the second supporting plate. According to the knee joint orthosis capable of being elastically bound, the supporting plate can be pushed through the air cylinder telescopic rod to achieve angle opening and closing so that the knee joint of a patient can be conveniently driven to be corrected, the worn protection soft cushion can be detached and replaced, and during replacement, only the hook-and-loop fastener round face on the protection soft cushion needs to be torn off from the hook-and-loop fastener hook face; the wearing flexibility can be improved through the first bonding binding band and the second bonding binding band, and the problem that auxiliary correction, replacement and replacement are inconvenient is solved.

The invention belongs to the technical field of knee joint orthotics, and discloses a four-bar linkage knee orthotics applying a fabric sensor, which integrates a gait self-adaptive instantaneous center adjustable hinge module through the design of a four-bar linkage mechanism, and shows extremely high flexibility and stability. By applying the mechanical bionics principle, the instantaneous rotation center track of the knee joint of a wearer is comparable with that of the knee joint in a normal physiological state, so that the corrector can be adaptively adjusted according to the gait and walking habit of a user, and a more fitting and natural auxiliary effect is provided. The stretching aid adopts a'safety belt 'locking mechanism and a'quasi-lever' stretching aid mechanism, so that the safety in the using process is remarkably improved, meanwhile, the body burden of a wearer is effectively relieved, and the remarkable stretching aid effect is achieved.

A powered device augments a joint function of a human during a gait cycle using a powered actuator that supplies an augmentation torque, an impedance, or both to a joint. A controller estimates terrain slope and modulates the augmentation torque and the impedance according to a phase of the gait cycle and the estimated terrain slope to provide at least a biomimetic response. The controller may also modulate a joint equilibrium. Accordingly, the device is capable of normalizing or augmenting human biomechanical function, responsive to a wearer's activity, regardless of speed and terrain, and can be used, for example, as a knee orthosis, prosthesis, or exoskeleton.

The knee orthosis of the present invention includes a femoral cuff configured to engage with the upper leg of the wearer, a tibial cuff configured to engage with the lower leg of the wearer, and a hinge that pivotably connects the femoral cuff to the tibial cuff. The hinge has a femoral portion and a tibial portion, which engage with each other and include a shell configured to pivot relative to each other about a center of rotation. One shell includes an engagement surface facing a complementary engagement surface on the other shell. The engagement surface and the complementary engagement surface each have a shape corresponding to a part of an ellipsoid defined by a major axis extending in the sagittal plane, a minor axis perpendicular to the major axis, and the length of the ellipsoid along the major axis being longer than the length along the minor axis, and rotation around the major axis.

The invention relates to the technical field of medical rehabilitation machinery, in particular to a knee joint orthopedic brace and a using method thereof.The knee joint orthopedic brace comprises an upper frame matched with the thigh contour and a lower frame matched with the shank contour, wearing assemblies are arranged on the two sides of the upper frame and the two sides of the lower frame, and the two sides of the upper frame and the two sides of the lower frame are hinged through bionic joint assemblies; the bionic joint assembly is provided with a power assisting assembly, and the side end of the power assisting assembly is provided with an adjusting and locking assembly for adjusting and locking the movement angle of the knee joint. Through work of the bionic joint assembly and the adjusting and locking assembly, the walking posture of a patient can be adapted, meanwhile, flexible adjusting and locking can be achieved, and practicability and convenience are greatly improved.
