Description

A lower limb good limb position support frame

technical field

The utility model relates to the technical field of good limb position, in particular to a lower limb good limb support frame.

Background technique

After the treatment of lower extremity diseases, sequelae such as hip joint external rotation, foot drop, and foot valgus often occur. Therefore, during the rehabilitation process of patients, passive postures such as hip joint internal rotation, ankle dorsiflexion, and plantar joint varus must be maintained to prevent patients from Limb deformation, contracture, improve the function of the affected limb, and promote the rehabilitation of the affected limb to walk. In patients with lower limb diseases, the muscle strength of the lower limbs is often reduced to grade 0, and they cannot move automatically, and artificial methods must be used to maintain a good limb position. At present, the methods adopted for maintaining the benign functional position of the lower limbs mostly use items such as pillows and cotton pads to position the affected limbs, and some use fixed boards to realize inversion of the feet. It still maintains an advantage, so it is difficult to maintain a good limb position. Simple fixation of the foot has a certain varus effect on the foot, but in the case of knee valgus, the fixation effect of the good limb position is poor, and the current The angle of the foot cage used cannot be adjusted and cannot vary from person to person.

And be used for lower limbs good limb position support frame now often structure is too fixed and is not convenient for patient's lower limbs to stretch properly, and structure is too complicated.
