Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further described.
Fig. 3 is the front view that knee joint MR checks fixture.
Fig. 4 is the right pseudosection that knee joint MR checks fixture.
Fig. 5 is the right view that knee joint MR checks fixture.
As shown in Fig. 3, Fig. 4 and Fig. 5, knee joint MR checks that fixture comprises: base 10, foot fixation kit 20 and rotating shaft assembly 30.
The main structure of base 10 is trapezoidal, increases the steadiness of base.Base 10 comprises positioning boss 11, coil coordination boss 12, elastomeric pad 13 and arc groove 14.Arc groove 14 is arranged on the upper surface of base 10.
Coil coordination boss 12 is arranged on the front end of base 10.Coil coordination boss 12 is circular arc.Can certainly the height of coil coordination boss 12 identical with the height of knee joint coil, the internal diameter as preferred circular arc is identical with the internal diameter of knee joint coil.
Positioning boss 11 is arranged on the rear end of base 10, has locating hole.Elastomeric pad 13 is also circular arc, fits with the circular arc of coil coordination boss 12.
Coil coordination boss 12, elastomeric pad 13 and arc groove 14 are circular arc, and three is isocentric circular arc.
Foot fixation kit 20 shape of a hoof, has arc surface 24 and two barrier plates 21.Arc surface 24 and arc groove 14 are fitted and are arranged.The circular position of arc surface 24 has locating hole.
Barrier plate 21 is arranged on the both sides of horseshoe-shaped foot fixation kit 20.The distance scalable of two barrier plates 21, can relative to moving inward or outwards moving.
The side of foot fixation kit 20 also has angle index 22, determines the position regulated when convenient adjustment.Certainly, angle index can also be arranged on the place of the handled easily personal observations such as front end face or rear end face of foot fixation kit 20.
Foot fixation kit 20 and positioning boss 11 are rotatably connected by rotating shaft assembly 30.Wherein, rotating shaft assembly 30 is arranged on the axis of arc surface 24.
Rotating shaft assembly 30 comprises bolt 31, shim pack 32 and nut 33.
Bolt 31 passes from the locating hole of foot fixation kit 20, then through after the locating hole of positioning boss 11, is connected with shim pack 32 and nut 33, makes foot fixation kit 20 can respect thereto 10 left rotation and right rotation.
Knee joint MR checks fixture work process:
Fig. 6 is 15 degree of structural representations of turning left that knee joint MR checks fixture.
Fig. 7 is 15 degree of structural representations of turning right that knee joint MR checks fixture.
As shown in Figure 6 and Figure 7, first unclamp nut, by foot fixation kit left or to right rotation 15 degree, can regulate according to the scale of foot fixation kit side during rotation, after completing adjustment, fastening nut.Apply lubricant between arc groove 14 and arc surface 24, between rotating shaft assembly parts, reduce spin friction resistance.
Knee joint MR checks that fixture is placed on the rear of knee joint coil, is inserted by elastomeric pad in the endoporus K of knee joint coil, can make up different knee joint coil like this and knee joint MR checks the difference in height that fixture exists.
Then, foot is goed deep into knee joint coil by patient, is placed on elastomeric pad, and foot is placed on foot fixation kit, and the distance between mobile barrier plate 21, is fixed on the foot of patient on foot fixation kit.Now, the knee of patient, in 15 degree laterally, then carries out knee joint MR inspection.
