Have so theory in mathematics: there are such point in the surrounding space of any one triangle, these points are special That to be to three vertex of triangle be point is isometric, and such point is point-blank.Plane where this straight line and triangle Vertically, with the center of circle of the intersection point of gore its actually triangle circumscribed circle.

The uniaxial joint rotary motion of human body limb is exactly to draw circle in fact, and uniaxial joint rotary middle point is the center of circle, rotation Shaft is straight line vertical with the plane of joint rotary motion and by rotary middle point.When joint one end is fixed, the other end is done Rotary motion enables another end motion if the proximal end of fixed suffering limb body is in static state, and the limbs of distal end are substantially to close in fact Saving rotary middle point is that circle is being drawn in the center of circle, and rotary shaft is actually vertical with the circle and passes through the straight line in the center of circle, the present embodiment provides Joint rotation shaft position meter purpose be to measure the rotary shaft of uniaxial joint.O point is fixed in the one end in joint, in quiet State, the other end rotate, we take the fixed point on tache motorice, instruct fixed point rotary motion, and fixed point arbitrarily stops Three-dimensional point A1, A2 and A3 where recording each fixed point three times are stayed, these three fixed points are a triangle, this triangle The circumscribed circle center of circle of shape is on the straight line where the rotary shaft in joint, wherein the distance of the vertical line of fixed point to rotary shaft For the radius of circumscribed circle.After any three points on motion profile determine, an actually triangle, and the track of above-mentioned circle is then The circumscribed circle of this triangle, taking two groups three isometric straight line steel needles, (length need to be greater than the radius of circumscribed circle, and two groups of straight lines The length of steel needle need to have certain length difference), one end of first group of three straight line steel needle is individually placed to three above-mentioned movement rails Three vertex of the triangle on mark, the other end intersect at a point, same to operate, then do another group of isometric straight line steel needle intersection In another point, the line of two crosspoints is straight line, the straight line and the center of circle and and the triangle for passing through triangle circumscribed circle The plane at place is vertical.The joint rotary shaft of this straight line namely our needs.

Referring to principles above, to operate joint rotation shaft position meter, specifically includes the following steps:

One, shown in Figure 16, affected limb fixator and three the second loggers are connected on multiple second slide bars, will be suffered from The proximal part of limb is connect by sclerotin fixed pin with affected limb fixator first, and enables the position of affected limb fixator not with respect to frame body Become, realizes suffering limb proximal part bone photo and frame body is fixed, distal end is connect for second with the first logger, enables the first logger The first sphere the centre of sphere as rotation fixed point, enable the first logger along suffering limb proximal part rotate, during rotation, First position stops, and first the second logger is enabled to move along frame body length direction, width direction and short transverse, to enable the First the first groove of two loggers is corresponding with the first sphere of the first logger, at this point, enabling the position of the second logger Opposite frame body is constant, realizes and fixes this first position, is recorded as B1 point；Above step is repeated, other two the second note is enabled Device record B2 point and B3 point are recorded, as shown in figure 17；

Two, shown in Figure 18, by the 5th logger, second is connected on the second slide bar；Three third loggers are taken, The first part of three third loggers is not placed in first groove of three the second loggers, the of three third loggers Two meet at a point E1 far from first side, enable the 5th logger along frame body length direction, width direction and height side To movement, to enable first of the 5th logger to be overlapped far from the 5th logger second side with the above crosspoint, It enables the position of the 5th logger constant with respect to frame body, realizes and fix the position of E1 point；

Three, shown in Figure 19, by the 6th logger, second is connected on the second slide bar, enables the 6th logger along frame body Length direction, width direction and short transverse are mobile, the centre of sphere and the above-mentioned 5th where the second groove to enable the 6th logger The position E1 that logger is recorded is overlapped, and enables the position of the 6th logger constant with respect to frame body, to enable the second of the 6th logger The centre of sphere of groove records the position of E1 point；

Four, shown in Figure 20, the 5th logger second of second the 5th logger is connected on the second slide bar； Three the 4th loggers are taken, the first part of three the 4th loggers is not placed in first groove of three the second loggers, Second of three the 4th loggers meets at a point E2 far from first side, enables second the 5th logger along frame body length Direction, width direction and short transverse are mobile, and the 5th logger first to enable second the 5th logger is separate described The side of 5th logger second is overlapped with the above crosspoint, enables the position of second the 5th logger constant with respect to frame body, It realizes and fixes the position of E2 point；

Five, referring to fig. 2 shown in 1, the 6th logger second of second the 6th logger is connected on the second slide bar, Second the 6th logger is enabled to move along frame body length direction, width direction and short transverse, to enable second the 6th record The centre of sphere where second groove of device is overlapped with the position E2 that above-mentioned 5th logger is recorded, and enables the position of second the 6th logger Set that opposite frame body is constant, to enable the centre of sphere of the second groove of the 6th logger record the position of E2 point；

Six, referring to fig. 2 shown in 2, record ball is placed respectively in the second groove of two the 6th loggers, and adjust record Position of the ball in the second groove, to enable the axis direction of first through hole of two record balls be overlapped；

Seven, referring to fig. 2 shown in 3, steel needle is sequentially passed through to two first through hole of two record balls, at this time the axis of steel needle Direction is the axis direction of the rotary shaft in suffering limb joint, realizes the rotary shaft of measurement uniaxial joint.

In conclusion joint rotation shaft position meter provided in this embodiment by measuring suffering limb joint in three-dimensional space Rotary shaft；In addition, another limb can be released by the symmetry of human body both limbs by acquiring the rotary shafts of strong side limbs The rotary shaft of body；Furthermore rotation shaft position meter in joint provided in this embodiment is suitble to the measurement of all size joint, including whole body Whether the bilateral in symmetry joint measures, symmetrically go to assessment joint to restore function situation in combination with bilateral rotary shaft.

The additional aspect and advantage of the utility model will become obviously in following description section, or practical new by this The practice of type is recognized.
