Embodiment

[0035] An adjustable posture and loading ankle immobilization device, the structure of which is as follows Figure 1-4 As shown, it includes the overall frame, which is arranged in the overall frame, and the plantar force loading control component that loads the sole of the foot and receives the control signal is connected with the sole force loading control component to rotate the sole of the foot and fix the position of the sole of the foot. Rotation and retention The component is a leg moving and retaining support component which is arranged in a direction at right angles to the overall frame and fixes the position of the leg. Each component is described in detail below.

[0036] The overall frame is composed of an outer profile bracket, a double-sided slide bar 7, and a four-corner guide slide bar 2. The double-sided slide bar 7 is located on both sides of the leg moving and retaining support assembly, and the leg moving and retaining support assembly can move along the bi...

Abstract

The invention relates to an ankle fixing device capable of adjusting posture and loading. The ankle fixing device comprises a main frame, a pelma force loading control assembly, a sole rotating retention assembly and a leg moving retention supporting assembly, wherein the pelma force loading control assembly is arranged in the main frame and used for loading force to the pelma and receiving a control signal; the sole rotating retention assembly is connected with the pelma force loading control assembly and used for rotating the pelma and retaining the position of pelma; the leg moving retention supporting assembly is arranged in a straight angle relative to the main frame and used for fixing the positions of legs. Compared with the prior art, the ankle fixing device has the advantages that the structure is simple, the scanning of a CT (Computed Tomography) machine applies, the ankle anatomical parameters can be measured under different postures and different force loading environments, and therefore, the obtained ankle joint anatomical parameters can be calculated and analyzed; the ankle fixing device can also be applied to a common leg retention device and is suitable for people of different sizes.

Description

technical field [0001] The invention relates to an ankle fixation device, in particular to an ankle fixation device with adjustable posture and loading. Background technique [0002] The ankle joint is one of the main load-bearing joints of the human body. It is formed by the tibia, the lower end of the fibula and the talus. Important joint for the weight-bearing form of the arcuate plane. [0003] Total ankle arthroplasty is an operation that replaces the damaged joint that cannot be used normally with an artificial ankle joint, solves pain, deformity and dysfunction, and restores and improves the ankle joint movement function. Compared with ankle fusion, a procedure that causes bony stiffness in the joint, ankle replacement preserves a greater portion of the ankle's freedom of movement and improves postoperative quality of life. However, at present, the medium and long-term curative effect of total ankle arthroplasty is not ideal, and there are problems such as prostheti...
