Detailed Description

The technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention.

As shown in fig. 1, the utility model discloses a knee joint auxiliary flexion and extension function exerciser, which comprises an exercising body 1, and a first stretching strap 2, a second stretching strap 3 and an elastic member 4 which are arranged on the exercising body 1. Wherein, exercise body 1 supplies the patient to wear on the foot that the knee joint need recover after the operation, when implementing, can be a pair of shoes. In the case of a pair of shoes, the exercise body 1 comprises in particular a sole 11, a vamp 12, a toe cap 13 and a heel 14.

The first drawstring 2 and the second drawstring 3 are respectively positioned at two sides of the exercise body 1 and are used for being held by the hands of a patient to drive the knee joint to perform flexion and extension actions. Specifically, first stretching strap 2 and second stretching strap 3 all include

relative head end

21, 31 and

tail end

22, 32, and wherein, head end 21 of first stretching strap 2 and head end 31 of second stretching strap 3 all connect in the bottom of exercising body 1, like sole 11, preferably,

head end

21, 31 of first stretching strap 2 and second stretching strap 3 all are connected with exercising body 1 detachably, and during the implementation,

head end

21, 31 of two stretching straps 2, 3 can be connected with exercising body 1's bottom through detachable hasp 23, 33.

The tail ends 22, 32 of the first pull belt 2 and the second pull belt 3 are used for being pulled by the hands of the patient, and preferably,

pull rings

24, 34 for the hands of the patient to extend into and pull are arranged at the

tail ends

22, 32 of the two pull belts 2, 3. In addition, the first drawstring 2 and the second drawstring 3 have no elasticity as a whole, and a nylon belt can be adopted during specific implementation; and the length can be adjusted, and the length can be adjusted at least until the patient lies down, the tail ends 22 and 32 of the drawstrings 2 and 3 can be pulled by hands.

The elastic part 4 is arranged on the exercise body 1 and used for providing the buffering force required by the flexion and extension actions when the patient does the flexion and extension actions of the knee joint. The elastic member 4 also includes opposite head end 41 and tail end 42, and when in use, the head end 41 of the elastic member is connected to the bottom of the exercise body 1, and may be disposed at the middle position of the bottom of the exercise body 1, or disposed at the middle position close to the bottom of the exercise body 1.
