Specific embodiment
The utility model is further described with specific embodiment with reference to the accompanying drawing, referring to Fig. 1-5:
A kind of knee joint stress variable correction brace, as shown in Figure 1, including 1 He of upper bracket being fixed on patient thigh
The lower bracket 2 being fixed on patient's shank, upper bracket 1 include two pieces of epipleural 1a and are connected to upper at the top of two pieces of epipleural 1a
Arc panel 1b, three in one injection molding；Lower bracket 2 includes two pieces of lower side panel 2a and the lower arc for being connected to two pieces of lower side bottoms
Shape plate 2b, three in one injection molding；Lateral arcuate socket 7 is offered in the middle part of upper arc panel 1b, is opened up in the middle part of arc lower plate 2b
There is lateral arcuate socket 7, to increase the toughness of two pieces of arc panels, is preferably fitted in patient legs surface.
In conjunction with Fig. 2 and Fig. 3, the lower end of ipsilateral epipleural 1a and the upper end of lower side panel 2a are engaged by sector 10
It links and is rotatably connected on main connection seat 3 by axis 12 respectively, the epipleural 1a and lower side panel 2a common rotation of the other side connect
It connects on duplicate invoice joint chair 4, the main setting of connection seat 3 is arranged in patient's knee joint side duplicate invoice joint chair 4 in patient's knee joint other side；
The epipleural 1a medial surface and lower side panel 2a medial surface of main 3 side of connection seat are distributed with strain protrusion 11, strain raised 11 top surfaces
Height be gradually reduced from one end to the other end and；Main 3 fit inside of connection seat has top plate 5, and 5 back side of top plate is fixed with two up and down
Mandril 9, mandril 9 are laterally threaded through the top surface that on main connection seat 3 and head is respectively acting on two strain protrusions 11.Answering here
Becoming protrusion 11 can be any shape, such as ellipse, arc, strip, if the linkage of guarantee upper bracket 1 and lower bracket 2 so that
Two mandrils 9 strain raised 11 top surfaces and hoist walking from high to low or by lower simultaneously along respective；For beautiful and knot
Structure compactedness, the preferably arcuate structure of strain protrusion 11, and two strain protrusions 11 are mirrored into symmetrical；On epipleural 1a
Using the rotation of epipleural 1a point as the center of circle, the strain protrusion 11 on lower side panel 2a is strain protrusion 11 with the rotation point of lower side panel 2a
The center of circle, wherein 5 surface of top plate is equipped with flexible support 6.
Wherein, the upper arc panel 1b is towards front evagination, and the arc lower plate 2b is towards back side indent, upper arc panel 1b
It is fitted in thigh front, arc lower plate 2b is fitted in the shank back side.So set, two pieces of arc panels are just located at when bent leg
On leg exercise direction, leg is more preferably supported, meets ergonomics, is dressed more comfortable.
Wherein, the upper bracket 1 and 2 two sides of lower bracket are respectively equipped with bandage attachment base 8.Bandage attachment base 8 is loaded onto removable
The bandage unloaded realizes the fixation of upper bracket 1 and lower bracket 2 on patient legs.
The concrete principle of the brace is as follows:
As shown in figure 4, two mandrils 9 are located in the high position for straining raised 11 top surfaces at two when patient legs stretch,
Since upper and lower bracket 2 is fixed on leg, 11 pairs of mandrils 9 of strain protrusion apply the power towards knee joint direction at this time, top
Bar 9 pushes top plate 5 to hold out against the knee joint in patient, plays correcting function；
As shown in figure 5, upper bracket 1 rotates clockwise, and lower bracket 2 rotates counterclockwise, two mandrils when patient legs are bent
9 from straining the high-order mobile to low level of raised 11 top surfaces, and strain protrusion 11 gradually decreases the active force to mandril 9, and top plate 5 is no longer
The knee joint in patient is held out against, plays the role of releiving to knee joint in bent leg.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by the protection of the utility model
Within the scope of.
