Abstract

The invention discloses a stretching assisting orthosis of knee joints. The orthosis comprises a thigh orthopedic piece, a shank orthopedic piece, an elastic belt in the stretching state and two knee connection pieces. Two ends of the knee connection pieces are symmetrically fixed on two sides of the shank orthopedic piece, and the other two ends are symmetrically linked to two sides of the thigh orthopedic piece. One end of the elastic belt is connected to the front surface of the thigh orthopedic piece and the other end is connected to the front surface of the shank orthopedic piece. According to the invention, by using the elastic belt to stretch the thigh orthopedic piece and the shank orthopedic piece, it can be achieved that firstly when a patient is walking, quadriceps femoris is assisted to perform active motion, knees of the patient are stretched during buckling and the knee joints are stretched straight; and secondly when the patient is not walking, the orthosis can be used for training ham string tendons and musculus gastrocnemius to perform resistance motion so as to enhance muscle force of lower limbs, thereby achieving an effect of stabilizing the knee joints.

Description

technical field

[0001] The invention relates to the field of medical devices, in particular to a knee joint extension-assisted orthosis. Background technique

[0002] At present, many patients are unable to stand with their lower limbs due to nerve damage, quadriceps weakness, or mild knee flexion contracture, or cannot keep their knees straight when standing, which seriously affects their normal life, study and work. , and sometimes discriminated against.

[0003] However, many patients, especially adolescents, can use auxiliary orthotic devices for joint correction, which will effectively improve this situation and return to normal life, study and work. Contents of the invention

[0004] The present invention aims to solve at least one of the problems existing in the prior art.

[0005] The technical problem to be solved by the present invention is to solve the problem that patients cannot stand with their lower limbs due to nerve damage, quadriceps muscle weakness, or...

Embodiment

[0020] This embodiment provides a knee joint extension orthosis, such as figure 1 Shown is a thigh orthosis 1 , a lower leg orthosis 2 , an elastic band 3 in tension, a foot orthosis 4 , two ankle links 6 and two knee links 5 .

[0021] One end of the knee connector 5 is arranged symmetrically on both sides of the lower leg orthotic 2, and is fixedly connected to the lower leg orthotic 2 through at least two screw rods 7, and the other end of the knee connector 5 is symmetrically arranged on On both sides of the thigh orthotic 1, the knee connector 5 is linked with the thigh orthosis 1 through a screw rod 7, and the flexible connection is realized through the link, so that when the patient wears this embodiment for knee correction , It can also realize the bending of the knee, which is convenient for the daily life of the patient.

[0022] Protrusions 81 are provided at the joints of the thigh orthosis 1 and the knee connector 5 and at the junction of the calf orthoped 2 and ...
