Description
Technical field
The present invention relates to a kind of ligament of hip joint tensity measuring instrument.
Background technology
It is fairly simple for the measuring method of ligament of hip joint tensity, original at present.Mostly it is experimenter's sitting position, makes
Measured with protractor.The method of experimenter's sitting causes hip joint in measured, the survey of this method under 90 degree of states
Amount result is inaccurate；In addition, standard of these diagnostic methods due to shortage specification, easily because of applying power in measurement process
Amount of different sizes and cause measurement result inaccurate, measurement reproducibility is poor, it is difficult to which ligament of hip joint tensity is given
Precisely quantify, be not suitable with the needs of current modern scientific research.
The content of the invention
For the deficiencies in the prior art, the invention provides a kind of ligament of hip joint tensity measuring instrument, is surveyed using clinostatism
Examination posture, in test process joint angles displacement is avoided, it is ensured that the concordance of multiple push-pull effort.
The technical scheme is that：
A kind of ligament of hip joint tensity measuring instrument：Including the gripper shoe for experimenter's prostrate；One keeps out plate is fixed on support
One end of plate simultaneously keeps and the angle between gripper shoe is 90 degree, and the knee joint for keeping out plate for making experimenter bends in 90 degree；
Installing in the gripper shoe side can be along the portable plate rotated perpendicular to body direction, and portable plate is provided with can fix experimenter
Fixed cell of the knee joint in 90 degree of bendings, and portable plate is provided with pull and push dynamometer；When the knee joint of experimenter is supported by described
When baffle plate is presented 90 degree of bendings, plate will be kept out and unloaded, make experimenter's knee joint be kept for 90 degree using the fixed cell, to described
Pull and push dynamometer applies push pull maneuver, and portable plate drives the femur of experimenter to be rotated around hip joint, while using measurement dress
Put the angular shift for determining hip joint.
Further, the fixed cell includes that the first fixed part being fixedly connected on the portable plate and second is fixed
Portion, is respectively used to fix the knee joint of experimenter near shank side and knee joint near thigh side.Its advantage is：Fixation side
Formula is simple, firmly effectively, easy to use, prevents knee joint from changing with kneed angle in portable plate rotation process.
Further, using rope, the portable plate is provided with rope through hole for first fixed part and the second fixed part, and rope is used
The extraction lateral edges of through hole have fastener structure, and rope can be obtained from the introducing side of rope through hole and penetrated freely, and be passed from outlet side,
Rope is set to be in locking state by using active force；Its advantage can be further fixed kneed angle of bend,
In test process, the angle is not easy change, it is ensured that the rotational angle of the portable plate is synchronous with the rotational angle of femur consistent,
Thus test result is more accurate.
Further, one end of the gripper shoe offers multiple groove ports, and the plate of keeping out is including chimeric the plurality of
The male part of groove port；Its advantage is：Keeping out plate firm must can fix on the supporting plate, 90 degree of angles therebetween
Will not arbitrarily change, and keep out plate freely to dismantle.
Further, hollow bulb is offered in the gripper shoe, described plate is kept out for placing；Its advantage is to work as to make
With finishing after the measuring instrument, can will keep out plate and be placed in gripper shoe, floor space is little, beneficial to storage, convenient use.
Further, the portable plate is provided with vertical rail, and vertical rail both sides is equipped with the locking of track-movable
Construction, the pull and push dynamometer can be moved freely in vertical rail, and it is described vertical that pull and push dynamometer is securable to by fastener structure
The a certain position of track, is applied in push pull maneuver；Its advantage can be the level height for arbitrarily changing pull and push dynamometer in portable plate
Degree, changes torque, because the lower limb length of different experimenters is different, needs the position for being directed to the force that different experimenters change pull and push dynamometer
Put.
Further, the portable plate is arranged in the gripper shoe by connecting shaft, one end of connecting shaft and the work
Dynamic plate connection, the other end is flexibly connected with the gripper shoe.
Further, the activity is arranged in the gripper shoe by folding, and one end of folding connects with the portable plate
Connect, the other end is flexibly connected with the gripper shoe.
Further, the measurement apparatus adopt the measurement arm of electronic angle gauge, electronic angle gauge to be fixed on the activity
On plate, it is synchronized with the movement with portable plate, the fixed arm of electronic angle gauge is perpendicular to ground；Its advantage is：On the one hand work as and pass through
When portable plate rotates femur, directly the rotational angle of femur can be judged according to the rotational angle of portable plate, be judged quick and precisely；
On the other hand, the rotational angle of the femur that is connected with hip joint can be continuously recorded, with reference to pull and push dynamometer, femur rotation can be measured
During angle consecutive variations, the size of hip joint institute holding capacity.
Further, the gripper shoe both sides be respectively provided with can installation activity plate connector, when experimenter has surveyed side hip
Behind joint, portable plate can be unloaded, be attached to opposite side, measure the tensity of another side hip joint.
Compared with prior art, the invention has the beneficial effects as follows：
The present invention measures the tensity of hip joint using experimenter in prone position, and such setting is better than being in experimenter
The posture measurement of sitting, when reason is that experimenter is in standing and sitting gesture, hip joint is in 90 degree, it is impossible to accurately draw experimenter
Hip joint tensity, and method before is not fixed due to each position, its joint angles can be during test
Change；Secondly, the present invention can quantify the outer of applying using keeping out by the way of plate and portable plate combination according to pull and push dynamometer
Power size, to determine the angle that range of motion stops.
The limbs that knee joint connects are fixed using fixed cell, fixed form is simple, firmly effectively, user
Just, can prevent knee joint from changing with kneed angle in portable plate rotation process；When being measured using the measuring instrument, no
Femur only can be effectively rotated rapidly, and ensure that the rotational angle synchronous with the rotational angle of femur one of portable plate
Cause.
