Abstract
The utility model discloses a knee joint outward turning angle measuring device, which is composed of a support rod, a bottom board, an angle ruler, shipform foot supports, and handle rods, the support rod is connected with the back surface of the bottom board and forms a support frame with the lower side of the bottom board, the right side of the bottom board is installed with a plane semicircle angle ruler, the bottom planes of the two ship form foot supports are correspondingly arranged at two sides of the longitudinal central line of the angle ruler plane, the ship form foot supports, the angle ruler and the bottom board are hinged as one by a pin; the inner side edges of the opposite two ship form foot supports are in a straight line and form a conical angle relative to the longitudinal central line of the angle ruler, and the handle rods is arranged on the ship form foot supports in the vertical direction, to form the knee joint outward turning angle measuring device. The utility model can intuitively measure the knee joint outward turning angle, reduce the measurement step and error, and save labor and shortage the measurement time. The utility model has the advantages of simple structure, convenient use, and high measurement accuracy.
Description
Affiliated technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of knee joint outward turning angular surveying device.
Technical background
In the treatment of motion surgical clinical, knee joint injury is a frequently-occurring disease, and then complex damage in the outside is one of damage of knee joint more complicated.The outer complex damage in back can cause external rotation instability after the knee joint.To back unsettled error diagnosis of external rotation and treatment, the anterior cruciate ligament of reconstruction or posterior cruciate ligament were lost efficacy, therefore unsettled correct diagnosis is very important to the back external rotation.For the error diagnosis of back outer complex damage be mainly derived to the outer complex inspection in back be familiar with inadequately.After the common inspection method of outer complex damage have that physics is had a medical check-up, X line and nuclear magnetic resonance check.Yet the back external rotation instability that causes for damage can only be by the physics detection of having a medical check-up, and comprises that outward turning dialing test, the outward turning recurvation of enuflex position levied, the outer drawer test in back etc.The outer drawer test in back of seeking peace of outward turning recurvation differs greatly according to examiner's difference and can not quantize to rotate unsettled degree, when therefore measuring outward turning dialing test the between perpendiculars angle of biped medial border and heel horizontal plane become quantize after the external rotation instability physics main method of having a medical check-up.For outer complex damage after the knee joint, outward turning dialing test operation can obtain quantizating index simply again.But there is following shortcoming in outward turning dialing test: the first, and need measure by the back computer of taking a picture and just can obtain knee joint outward turning angle; The second, need more than 2 medical assistant to carry out auxiliary detection and just can finish; The 3rd, the operator makes and with the hands the outward turning of experimenter's biped is difficult to operation and outward turning strength inequality and biped can't be followed the maintenance level.Therefore, research and develop a kind of easy to use, simple in structure, under single medical assistant's help, just can carry out the measurement of knee joint outward turning angle, and the knee joint outward turning measuring device that can read patient's outward turning angle rapidly intuitively is the task that the current urgent need in this area is finished.
Summary of the invention
The purpose of this utility model be to provide a kind of easy to use, simple in structure, measure the knee joint outward turning angular surveying device that accurately and intuitively shows the outward turning angle.
In order to achieve the above object, this utility model adopts the technical scheme of following structure: a kind of knee joint outward turning angular surveying device, form by support bar, base plate, bevel protractor, the holder of ship shape foot, handlebar stem, be characterized in: support bar is fixedlyed connected with the base plate back side, and constitute bracing frame with base plate is horizontal following, plane semicircle bevel protractor of fixed installation on the base plate horizontal frontal plane, two ship shape foot backing plane correspondences are placed on longitudinal centre line both sides, bevel protractor plane, and ask bottom and semicircle bevel protractor and base plate hinge to be connected to integral body on the ship shape foot by bearing pin; Two ship shape foot holder opposed inside edges are linear edge and relative angle chi plane longitudinal centre line formation taper angle; Two ship shape foot holder bottom surfaces, top are provided with vertical handlebar stem downwards respectively, thereby constitute knee joint outward turning angular surveying device.
Above-mentioned described support bar is the adjustable length bar and removably connects with being connected to of base plate.
Above-mentioned described handlebar stem and being connected to of ship shape foot backing face removably connect.
Paint redness on above-mentioned described two ship shape foot holder opposed inside linear edge, constitute and the corresponding red linear mark line of bevel protractor upper angle line.
Structure working principle of the present utility model is, the triangular support bracket support structure that is made of support bar and the horizontal bottom of base plate plays measuring device, be placed on the plane in the experimenter foot the place ahead that lies low, regulating support bar length makes the measuring device plane to experimenter's direction inclination certain angle, the holder of ship shape foot itself is the shoe-shaped structure just, with 2 sufficient restitopes put be adjusted into 0 the degree after, the tester puts into the holder of ship shape foot respectively with experimenter's biped, the experimenter takes dorsal position, the medical treatment assistant is with the two knee joints of patient 90 degree of going down on one's knees, and tibial plateau applied forward direction stress, the tester holds handlebar stem 2 foot holders is applied outward turning stress, can directly read knee joint outward turning angle by foot holder straight line inner edge red line mark line; Support bar and handlebar stem are demountable structure, when measuring device not the time spent can dismantle lower support bar and handlebar stem, be convenient to measuring device and deposit.
Owing to adopted the structural principle of above-mentioned measuring device, make this utility model can measure knee joint outward turning angle intuitively, and only need a medical assistant to help the tester to operate, save manpower, complex steps and error that photograph and computer are measured have also been reduced simultaneously, shorten Measuring Time, and easy to use, simple in structure, accuracy of measurement is high.

The specific embodiment
Below in conjunction with accompanying drawing in detail this utility model is described in detail, structural principle of the present utility model as can be seen from Fig. 1-Fig. 3, a kind of knee joint outward turning angular surveying device, by support bar 5, base plate 3, bevel protractor 1, ship shape foot holder 2, handlebar stem 6 is formed, the support bar 5 of adjustable length is fixedlyed connected with base plate 3 back sides, and with the horizontal following bracing frames that constitute of base plate 3, plane semicircle bevel protractor 1 of fixed installation on base plate 3 horizontal frontal planes, two ship shape foot holder 2 baseplane correspondences are placed on longitudinal centre line both sides, bevel protractor 1 plane, and ask 2 bottoms and semicircle bevel protractor 1 and base plate 3 hinges to be connected to integral body on the ship shape foot by bearing pin 4; Two ship shape foot holder 2 opposed inside edges are paints red linear edge and relative angle chi 1 plane longitudinal centre line formation taper angle; Two ship shape foot holder bottom surfaces, 2 top are provided with vertical handlebar stem 6 downwards respectively, thereby constitute knee joint outward turning angular surveying device.
