Abstract
Ankle joint rehabilitation traction equipment with adjustable joint angles comprises an external fixation shank tying band support, a right-side lead screw nut mounting block, a right-side lead screw nut mounting pin, a right-side lead screw nut rod, a right-side lead screw rod, a right-side universal coupling, a right-side rotating hand wheel, a right-side drive bevel gear, a right-side gear shaft mounting block, a gear shaft, a left-side gear shaft mounting block, a left-side drive bevel gear, a left-side rotating hand wheel, a planta pedis mounting support, a lower reed fixing rivet, a connection reed, an upper reed fixing rivet, a left-side lead screw nut mounting block, a left-side lead screw nut mounting pin, a left-side lead screw nut rod, a left-side lead screw rod, a left-side universal coupling, a right-side gear shaft mounting block screw, a left-side gear shaft mounting block screw, a left-side gear shaft bearing, a right-side gear shaft bearing and tying bands, wherein the external fixation shank tying band support and the planta pedis mounting support are located above and below the structure respectively. The joint angles of lower limbs and planta pedis ankle joints are adjusted through rotation of the left and right hand wheels, and rehabilitation traction training is realized.
Description
technical field [0001] The invention relates to an ankle joint rehabilitation traction device with adjustable joint angle, which belongs to the technical field of rehabilitation medical equipment. Background technique [0002] The ankle joint is an important load-bearing joint of the lower limbs of the human body. The normal walking, jumping and other activities of the human body are guaranteed by connecting the lower limbs with the plantar arch shock-absorbing structure. Ankle joint injuries, especially ankle ligament injuries, are one of the most common joint injuries. Without proper and effective rehabilitation measures, it will cause permanent damage to the ankle joint and eventually become disabled. [0003] In the current study, Xu Liju and others from Sichuan University designed an ankle joint rehabilitation training device in the patent CN 101006958A. The device has three degrees of freedom, two degrees of freedom of spherical motion and one degree of freedom of rot...
