Description
Technical field: this utility model relates to a kind of orthopedic rehabilitation apparatus.
Background technology
Along with the fast development of communications and building industry, high-energy damage constantly increases, and makes fracture more and more, and wherein fracture of the lower limb is the most common.In clinical position, the loading by lower limbs exercise that Patients with Fractures of Lower Limbs carries out science is after surgery the key that guarantees that limb function recovers smoothly, and the fine motion that fracture end is suitable and stress stimulation can significantly promote the growth of callus, the healing that acceleration is fractured.Fine motion makes fracture end deposit longitudinal compressive stress, increase the metabolic activity of osteocyte, osteoblast etc., impel PGE2 burst size to increase, promote angiogenesis, fine motion stress can cause the damage repeatedly of callus, cause repeatability fracture early reaction, discharge many biochemical mediators, promote union of fracture.Muscular motivation affects union of fracture; the normal activity in muscle and joint is to promoting that union of fracture plays an important role; the internal motivation that the activity of mechanicalness load muscle contraction produces makes fracture site continuous contact; closely intercalation; impel the moulding of union of fracture and new callus; therefore, new fractures theory thinks, the postoperative early stage suitable limited weight loading exercise of leaving the bed of patients with lower limbs fracture contributes to the reparation of skeleton and the rehabilitation of limb function.
First heavy burden function brace 1967 is sent out by artificial limb kneecap tendon load-bearing principle shoulder by Sarmiento, form tubularly according to shank shape fabricating, by ectocondyle in soft tissue, shin and kneecap tendon conduction external force, supports shank, successfully treats fracture of tibia [1-2].Again heavy burden function Brace Treatment tibia fractured near end far away has been carried out to more detailed analysis recently and summed up [3], and the successfully treatment [4] for fracture of tibia delayed union and disunion by brace.The barrel-like structure of brace holds shank soft tissue, makes soft tissue between knee joint and ankle joint in hermetic container, form hydraulic state, by hydraulic pressure mechanism, makes soft tissue and interosseous membrane maintain the stability of fracture length and the line of force.
Yet, different fine motion stress parameters have different impacts to union of fracture, and stress is crossed conference and caused fracture delayed union, and nonunion is fragmentation of internal fixation objects even, understressing is inoperative, thereby the treatment of fracture end fine motion stress stimulation needs accurately to control the stress that fracture end bears.Due to the real-time Stress Control, the monitoring that do not have at present corresponding medical apparatus and instruments (comprising above-mentioned heavy burden brace) for the accurate treatment of fracture end fine motion stress stimulation treatment needs.Cause most treatment of lower extremity fracture, still require patient in the therapeutic process of initial 2-3 month, strict bed rest, does not allow the heavy burden activity of leaving the bed.Long-term bed, is unfavorable for union of fracture, and patient is health and endurable mentally not only, and easily causes the complication such as decubital ulcer, phlebothrombosis, amyotrophy, osteoporosis, nonunion.

summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, the running gear that when the postoperative loaded exercise of a kind of auxiliary Patients with Fractures of Lower Limbs is provided, fracture face load is controlled and detected, can control and reduce the suffered stress of fracture limbs the suffered stress of real-time sensing fracture limbs, have rational in infrastructure, easy to use, the postoperative load monitoring of safe and reliable lower limb and decompressor.
This utility model is achieved in that and comprises leg-holder unit, sole air cushion or sole liquid pad, two cylinders or hydraulic cylinder; Two cylinders or hydraulic cylinder is communicated with sole air cushion or two hydraulic cylinders are communicated with sole liquid pad, leg-holder unit comprises proximal tibia standing part, footwear shape sole standing part, two cylinders or hydraulic cylinder are connected between proximal tibia standing part two sides and footwear shape sole standing part two sides, and sole air cushion or sole liquid pad are placed in footwear shape sole standing part.
During use, proximal tibia standing part is encircled ectocondyle in tibial plateau and femur, be wrapped on the following proximal tibia surrounding skin of patella, footwear shape sole standing part is worn on foot, sole is pressed in sole air cushion, when human body is stood, lower limb bear a heavy burden downwards, sole starts squeeze feet spirit pad or sole liquid pad, thereby sole air cushion or sole liquid pulvilliform capacity diminish, extruding gas or liquid are transported to cylinder or the hydraulic cylinder that is positioned at proximal tibia by conduit and pressure-control valve, after cylinder or hydraulic cylinder force, valve rod upwards ejects, make that proximal tibia standing part is stressed to move upward, proximal tibia standing part and footwear shape sole standing part and cylinder or hydraulic cylinder are combined to form ectoskeleton, health is played a supportive role.Before using, doctor is according to patient's condition, establish client need heavy burden weight, sole air cushion is squeezed into gas or the liquid to sole liquid pad injection specified quantity volume of specified quantity volume, make the hydraulic pressure of the original air pressure of sole air cushion or sole liquid pad reach predetermined value, reaching sole, to exert pressure with predetermined pressure sum be human body weight, thereby described method regulates the amount of heavy burden that suffering limb is born.
In order to facilitate the pressure of adjusting cylinders or hydraulic cylinder, to regulate footwear shape sole standing part, share the size of support force, be provided with two pressure-control valves, two cylinders are communicated with sole air cushion by two pressure-control valves respectively or two hydraulic cylinders are communicated with sole liquid pad by two pressure-control valves respectively.
