Embodiment 1

[0030] like figure 1 , figure 2 , image 3 , Figure 4 As shown in the figure, the device is a limiting mechanism composed of an installation sleeve 1 and a connecting sleeve 2 that is rotatably connected at one end of the installation sleeve 1. One end of the outer wall of the installation sleeve 1 is fixed with a drive assembly 3 that can control the rotational movement of the connecting sleeve 2. The connecting sleeve 2. The outer rotating sleeve is provided with a support sleeve 4. The inner support sleeve 4 is fixed with a clamping component 5 that can restrain and fix the lower limbs of the patient. The outer wall of the connecting sleeve 2 is fixed with an exhaust component that can control the contraction and expansion of the clamping component 5. 6;

[0031] The drive assembly 3 includes a motor 301 fixed on one end of the outer wall of the mounting sleeve 1 with functions of forward and reverse rotation, self-locking and low speed, a gear 302 fixed at the head en...

Embodiment 2

[0033] like Figure 5 , Image 6As shown, the strap 7 fixed at one end of the installation sleeve 1 slides through the sun-shaped buckle 8, the inner side of the strap 7 is sewn with a cushion 9, and the connecting sleeve 2 is integrally provided with a guide groove 10 inside, and the guide groove 10 slides inside The slider 11 is arranged to perform a circular motion with the center of the connecting sleeve 2 as the center of the circle, and the outer side of the slider 11 is fixedly connected with the support sleeve 4 to ensure the stability of the support sleeve 4 and the connecting sleeve 2 being concentric with each other. The function of sliding connection in the groove 10 prevents the support sleeve 4 from moving along the outer surface direction of the connecting sleeve 2 when the support sleeve 4 rotates. The threaded holes 13 integrally designed at the front and rear ends of the side are connected by means of threaded connection. The outer cover of the motor 301 and...

Abstract

The invention discloses a correcting device for treating knee osteoarthritis deformity, which comprises a limiting mechanism composed of a mounting sleeve and a connecting sleeve rotationally connected with one end in the mounting sleeve, a driving assembly capable of controlling the connecting sleeve to rotate is fixedly arranged at one end of the outer wall of the mounting sleeve, and a supporting sleeve rotationally sleeves the connecting sleeve. A clamping assembly capable of restraining and fixing the lower limbs of the patient is fixedly arranged in the supporting sleeve, and an exhaust assembly capable of controlling the clamping assembly to conduct contraction and expansion operation is fixedly arranged on the outer wall of the connecting sleeve. According to the device, the knee joint part of a patient is firstly clamped and positioned, then the angle of the clamped and positioned knee joint of the patient is adjusted, and in this way, the correction effect of the knee joint of the patient is improved.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a correction device for treating knee osteoarthritis deformity. Background technique [0002] Clinically, the patient presented with knee varus and knee valgus. There are congenital genetic factors as well as acquired secondary causes. There is a certain difference between knee varus and knee valgus. In appearance, knee varus is an O-shaped leg, and the distance between the two knees increases, while knee valgus is an X-shaped leg in appearance, and the distance between the two knees decreases. . The treatment methods are also different. Knee varus can be closed by a closed osteotomy, and a brace should be given after the operation, or a conventional wedge-shaped osteotomy of the proximal tibia can be used, and a correction brace should be worn after the operation. . Knee valgus requires conventional incision, supracondylar wedge osteotomy, and post-operative braci...
