Background technology
Ligamentous injury of knee joint is commonly encountered diseases and frequently-occurring disease, be common in athletic injury, accident causes sprain of knee joint, Falls in Old People is injured, treatment ligamentous injury of knee joint need to before operation in patients, postoperative knee joint outward turning stability be evaluated, to determine degree of injury and the therapeutic effect of knee ligament.The basis evaluating knee joint outward turning stability is by checking the angle that tibia rotates laterally relative to femur, needing resected femur during inspection, then reverses patients feet, observes the angle that tibia rotates laterally.The current this greatest problem checking existence is when reversing patients feet, the ankle joint of patient twists therewith, have a strong impact on the detection accuracy of tibia outward turning angle, therefore the ankle joint that special messenger holds patient must be had to be fixed, or adopt clamping plate and binder to check again after ankle joint is fixed, time-consuming, effort, and it cannot be guaranteed that the fixing stability of ankle joint.This inspection method is not accurate enough to the judgement of tibia outward turning angle simultaneously, also have impact on the evaluation accuracy to knee joint outward turning stability.In sum, the common method of current detection knee joint outward turning stability does not adapt to the needs for the treatment of, necessary is improved.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of knee joint tibial outward turning angle measuring instrument, this measuring instrument can get rid of the impact of the rotating factor of ankle joint, accurately measuring the angle that tibia rotates laterally relative to femur, the stability for evaluating knee joint outward turning provides reliable foundation.
The technical scheme solving above-mentioned technical problem is:
nullA kind of knee joint tibial outward turning angle measuring instrument，It includes angular measurement plate、Fixation brace for lower limbs、Femur bandage，Angular measurement plate and fixation brace for lower limbs are that rigid material is made，Fixation brace for lower limbs has two，Each fixation brace for lower limbs is made up of sole and two straps，Sole and human body sole shape adapt，The lower end of two straps is respectively perpendicular the both sides being connected to sole，The upper end of two straps is positioned at below knee joint，The front openings of two straps，The rear of two straps is connected，The front openings place of two straps has a plurality of bandage to be distributed up and down，Two soles are parallel to be placed on angular measurement plate，The plate face of sole bottom surface and angular measurement plate is sliding contact，The rear portion of sole bottom surface has rotating shaft to be connected with angular measurement plate，Angled scale on angular measurement plate.
Above-mentioned knee joint tibial outward turning angle measuring instrument, said two fixation brace for lower limbs parallel join is integrated, and the sole of two fixation brace for lower limbs parallel connection places, the angled pointer in sole front end of fixation brace for lower limbs.
Above-mentioned knee joint tibial outward turning angle measuring instrument, the angle index of described angular measurement plate is circumferential angle scale, the initial point of the rotating shaft at the sole rear portion of two fixation brace for lower limbs respectively two circumferential angle scales, the longitudinal axis of two circumferential angle scales is parallel with the length direction of sole, and the transverse axis of two circumferential angle scales is vertical with the length direction of sole.
The beneficial effects of the utility model are:
Double; two lower limb of patient can be fixed by fixation brace for lower limbs of the present utility model, after fixing, ankle joint can not rotate, it is to avoid ankle joint rotates the impact on tibia outward turning angle measuring；The angle index of angular measurement plate can demonstrate the angle that sole rotates exactly, therefore can accurately measure the angle of tibia outward turning.This utility model simple in construction, easy to use, measure accurately, it is possible not only to the angle difference comparing the strong side of patient in the preoperative with Ipsilateral knee joint outward turning, kneed outward turning instability is quantified, simultaneously postoperative be may also be used for evaluating the recovery extent of rotational stabilization after knee joint.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the top view of Fig. 1.
In figure, labelling is as follows: angular measurement plate 1, fixation brace for lower limbs 2, sole 3, two straps 4, bandage 5, rotating shaft 6, angle index 7, angle indicators 8.
Detailed description of the invention
This utility model is made up of angular measurement plate 1, fixation brace for lower limbs 2, femur bandage, and angular measurement plate 1 and fixation brace for lower limbs 2 are made for rigid material.
Showing in figure, fixation brace for lower limbs 2 has two, and each fixation brace for lower limbs 2 is made up of sole 3 and two straps 4.Sole 3 and human body sole shape adapt, the lower end of two straps 4 is respectively perpendicular the both sides being connected to sole 3, the upper end of two straps 4 is positioned at below knee joint, the front openings of two straps 4, the rear of two straps 4 is connected, and the front openings place of two straps 4 has a plurality of bandage about 5 to be distributed.
During use, the lower limb of patient and foot are put into fixation brace for lower limbs 2 from the front openings of two straps 4, then tighten fixing with bandage 5, strap 4 is rigid material, lower limb, ankle joint and foot can be fixed as one, ankle joint can not be rotated, it is to avoid ankle joint rotates the impact on tibia outward turning angle measuring.
Figure shows, two fixation brace for lower limbs 2 parallel joins are integrated, the parallel connection of sole 3 of two fixation brace for lower limbs 2 is placed on angular measurement plate 1, sole 3 bottom surface is close on the plate face of angular measurement plate 1, it is sliding contact with the plate face of angular measurement plate 1, the rear portion of sole 3 bottom surface has rotating shaft 6 to be connected with angular measurement plate 1, fixation brace for lower limbs 2 can be made to rotate centered by rotating shaft 6, the angle that fixation brace for lower limbs 2 rotates, the i.e. angle of tibial rotation is measured by angular measurement plate 1.Two sole 3 front ends are respectively arranged with a pointer, it is indicated that the corresponding anglec of rotation.
Figure shows, angled scale 7 on angular measurement plate 1, the angle index 7 of angular measurement plate 1 is circumferential angle scale, the initial point of rotating shaft 6 respectively two circumferential angle scales at sole 3 rear portion of two fixation brace for lower limbs 2, the longitudinal axis of two circumferential angle scales is parallel with the length direction of sole 3, and the transverse axis of two circumferential angle scales is vertical with the length direction of sole 3.
The angular measurement plate 1 of an embodiment of the present utility model makes for aluminium alloy plate, and fixation brace for lower limbs 2 is by duroplasts compression molding.
