Abstract

An external traction supporter for reducing the pressure on walking is composed of saddle, saddle wings, movable saddle wings, artificial hip joint, knee joint and condyle joint, and internal and external supporters for femur and tibiofibula. Said saddle is linked to saddle wings, to which movable saddle wings are connected via pins. The supporter of femur is connected to movable wings via artificial hip joint. The lower end of femur supporter is linked to the supporter of tibiofibula via artificial knee joint. The lower end of tibiofibula supporter is connected to artificial condyle joint. The lengthes of femur supporter and tibiofibula supporter are slightly longer than that of femur and tibiofibula, reducing the pressure to femur, knee joint, tibiofibula and condyle joint.

Description

External traction supporter for reducing walk pressure

External traction supporter for reducing walk pressure also can be called external femoral head, or the decompression artificial joint, is applicable to hip joint, femoral head, knee joint and ankle joint, the osteopathia at lower limb position, treatment of fractures.This decompression support is mainly used in the decompression treatment of femoral hip prosthesis head ischemia bland necrosis, also can be used for fracture fixation, motion, decompression, traction therapeutic.

Primary structure is by saddle 1 saddle left wing, right flank 2, movable block flap 3 and marrow joint 4,

knee joint

7,10 3 artificial jointes of ankle joint and

femur support

5,6 tibiofibula supports 8,9 form, practical purpose can reach by following measure: by saddle 1 and left and right sides block flap 2, movable block flap 3, form the pelvic cavity support, and be connected with axle center, movable block flap 3 front and back at saddle 1 front and back shaft core position and be two movable AnchorPoints 12, these two movable AnchorPoints are to be a line level with self axle center, marrow joint, two hip joints on the utilization movable wing, lay respectively at the femoribus internus outside and can make flexing 125 degree, after stretch 40 the degree, interior 30 degree of receiving, abduction 45 degree, medial rotation 45 degree, revolve outer 45 degree activities freely, movable hip joint 4 is connected with artificial thigh bone on the femur support, be Movable joint,

femur support

5,6 are connected with knee joint is a Movable joint, but flexing 140 degree, knee joint and

tibiofibula support

8,9 are connected is a Movable

joint.Tibiofibula support

8,9 is connected with ankle joint 10 and is a Movable joint, and bent 30 degree of the back of the body, warpage 45 degree, interior receipts abduction 15 degree, ankle joint 10 is connected with footwear or support with the ankle joint motions greatly in sufficient.

It is soft to add foam in each parts is all packed with leather, and

femur support

5,6

tibiofibula framves

8,9 have belt or nylon buckles and ligamentaum cruciatum and are used for fixing the thigh shank, and coordinative role and ligament draw are harmonious during as motion.

The decompression principle: be to utilize femur and tibiofibula support to be longer than self femur slightly, peroneotibial length supports the pressure that alleviates from heavy sensation of the whole body.

Motion principle: be motion, reach fixedly belt, nylon buckles and ligamentaum cruciatum traction coordinative role by artificial joint and femur, tibiofibula stent support by lower limb.

Exercise makes one strong, life is also in motion, suffers from osteopathia, the patient of fracture and femur head necrosis causes osteopathia because quantity of motion insufficiency of blood flow quantity reduces or slows down, fracture, or downright bad sclerotin metabolism deficiency, imbalance, amyotrophy, the joint space is narrow, because self pressure centrifugal force and displacement pressure, make necrotic femoral head be out of shape, subside, the articular cartilage wearing and tearing, pain has more been aggravated the difficulty of motion, the difficult restoring type of Drug therapy, impaired cartilage has caused very big difficulty for the generation of area of new bone, makes new bone be difficult to form, for preventing the generation of multiple factor, after morbidity, just utilize this support to alleviate pressure, reduce the articular cartilage wear-out failure, keep the joint space from heavy sensation of the whole body, walking movement makes blood circulation unimpeded, and can prevent amyotrophy, give the chance of regenerating bone or cartilage, the sclerotin early recovery that makes necrosis.

Practical principle: the belt fastener 11 on saddle 1 block flap is fixed in waist with belt, movable block flap 3 AnchorPoints 12 can make abduction and the interior axle center of receiving is supported from heavy sensation of the whole body, 4 decompressions of movable marrow joint are longer than self femur and peroneotibial length by

femur support

5,6 tibiofibula supports 8,9 and are supported pressure from heavy sensation of the whole body, install with femur support and shin calf rack surface, belt, nylon buckles and ligamentaum cruciatum be fixed in shank, keeps the motor coordination concordance.This external traction supporter for reducing walk pressure volume is light and handy, and dress is convenient, and motion freely, and is reasonable in design, handsome in appearance, be worn in the inside and outside clothing of wearing of body, elegant in appearance.Can give patient's peak exercise.Alleviate the patient suffering, exercise therapy combines and makes patient's early recovery.

The drawing of Figure of description is described as follows:

1. saddle; 2. block flap; 3. movable block flap; 4. hip joint; 5. femur support arm; 6. femur inner support; 7. knee joint; 8. tibiofibula support arm; 9. tibiofibula inner support; 10. ankle joint; 11. belt fastener; 12. movable AnchorPoint.
