Remote controllable modified pressure-regulating exoskeleton fixation device

Abstract

The invention relates to a remotely controllable deformable pressure-regulating exoskeleton fixing device comprising an adjusting bracket, a pressure-regulating device, a first fixing bracket, a second fixing bracket, a controller, a first bone needle, a tensile testing device and a damping type telescopic rod, a second bone needle, a limb and a fracture part. The adjusting bracket comprises a connector, a first adjusting ball cap, a telescopic rod, a second adjusting ball cap and an adjusting hole. The pressure-regulating device comprises a ball head sliding rod, a screw rod adjuster and a ball head sleeve. The damping type telescopic rod comprises a ball head hydraulic barrel, a double-ball piston, a piston cover, a ball head piston rod, a sealing cover and a steel ball. According to theremotely controllable deformable pressure-regulating exoskeleton fixing device, the first fixing bracket and the second fixing bracket are fixed at the first end and the second end of the fracture part respectively, stress of the fracture part is fed back in real time to the controller through the tensile testing device, which is beneficial to the rehabilitation of the fracture part. The remotelycontrollable deformable pressure-regulating exoskeleton fixing device has the advantages of stable structure and simplicity in operation and the like.

Description

technical field [0001] The invention belongs to the technical field of exoskeleton, and in particular relates to a remote controllable variable-form pressure-regulating exoskeleton fixation device. Background technique [0002] Fracture healing is a process of body self-healing, but there are many interfering factors, especially in the early stage of fracture, any rotation of the limbs is unfavorable, which will cause the rotation angle of the fracture to shift, such as premature weight bearing or poor alignment of the fracture, The pulling and shearing force of the muscles will cause adverse consequences such as shortening and displacement of the fracture, lateral displacement, and angular displacement. [0003] With the maturity of fracture treatment technology, conservative treatment methods such as splint and plaster can be selected for closed fractures, and internal fixation or external fixation brackets are required for open fractures. The external fixation brackets cu...

However, most of them ignore the influence of the physiological stress of the human body on bone growth, which makes it difficult for the bone to recover to its original strength and toughness during the healing process, and will cause bone loss, resulting in a longer period of time for the patient after the removal of the bracket. No strenuous activity for a period of time
