Abstract
The utility model discloses a tester for abducent myodynamia of lower limbs, which comprises a bottom plate (1), an upright post (2), a spring balance (3) and a leg warmer (4), wherein the upright post (2) is fixed on the bottom plate (1) and close to one side of the bottom plate (1), the upper part of the upright post (2) is transversally provided with the spring balance (3), and the retractable end of the spring balance (3) is connected with the middle part of the leg warmer (4) by a belt. The tester for abducent myodynamia of lower limbs can test the abducent myodynamia of a patient after total hip joint replacement, and reflect the test result in the digital form, and by virtue of accurate measuring data, the tester can carry out systematic research on posterior dislocation of femoral head, prosthesis looseness and the like; simultaneously, the tester has simple structure, simple and convenient operation and more accurate measuring data.
Description
Technical field
This utility model belongs to a kind of analyzer, specifically, is the analyzer that is used to measure lower limb abduction muscular strength behind a kind of replacement of total hip.
Background technology
Along with the development of medical science and the raising of people's living standard, the patient who femur head necrosis and fracture of femoral neck occur more tends to select to carry out replacement of total hip.In present replacement of total hip, most modus operandis needs the muscle group with control lower limb abduction, and just outward turning muscle group (comprising: piriformis, superior gemellus muscle, inferior gemellus muscle) cuts off, and will not sew up when operation finishes.The result who causes is exactly patient after surgery a little less than the outward turning muscular strength, and the femoral head backward dislocation takes place easily, and easy concurrent prosthetic loosening brings unnecessary misery for patient and family members thereof.At present to be used to study the method for femoral head backward dislocation and prosthetic loosening be all be by 6 grades of stagings by means of clinical experience to evaluate patient lower limb outward turning muscular strength power.That is:
0 grade of paralysis fully can not be done any freely-movable.
The visible muscle slight shrinkage of I level.
II level limbs can parallelly in bed move.
III level limbs can overcome the earth's core absorbing power, can be lifted away from bed surface.
IV level limbs can be done the motion of the extraneous resistance of antagonism.
V level muscular strength is normal, and motion freely
Though convenient by 6 grades of stagings, can't embody with data accurately, the owner sees the consciousness decision, to the relatively poor patient of some muscular strength, limits with doctor's level of ability.Can not carry out the research of system dataization, be unfavorable for research femoral head backward dislocation and prosthetic loosening.
The utility model content
Technical problem to be solved in the utility model is to provide measures the analyzer that lower limb abduction muscular strength can accurately be represented with numeral behind a kind of replacement of total hip.
The technical solution of the utility model is as follows: a kind of lower limb abductor force detector, its key is: be made up of base plate, column, spring scale, lower limb cover, wherein said column is fixed on the base plate, this column is near base plate one side, described column upper lateral is provided with spring scale, and the flexible end of this spring scale links to each other with lower limb cover middle part by belt.Need the patient that measures behind the replacement of total hip, will wear in the lower limb cover, the patient makes great efforts to abduction, the flexible end of pulling spring scale, and institute pulls out the numeral that flexible end upward marks and will show, for recording patient's abduction muscular strength.According to the size of outward turning muscular strength, select the big or small spring scale of dynamometry scope, select the higher spring scale of remolding sensitivity as far as possible.
Above-mentioned lower limb cover is for cylindric, and this lower limb set upper side is big, and the lower end is little, the shape of approximate thigh, described lower limb puts, in, the bottom is with an adjustable telescopic band respectively, the flexible end of described spring scale is connected with telescopic band in the middle part of the lower limb cover by belt.Can regulate the thigh that telescopic band is suitable for different fat or thin people, the flexible end of spring scale is connected more flexibly firmly by the telescopic band of belt with lower limb cover middle part.
Beneficial effect: this utility model can carry out the mensuration of abduction muscular strength to the patient behind the replacement of total hip, reflects with digital form, by accurate measurement data, is beneficial to femoral head backward dislocation and prosthetic loosening etc. are carried out systematic research; Simultaneously simple in structure, easy to operate simple, measurement data is more accurate.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Embodiment 1
As shown in Figure 1 and Figure 2, a kind of lower limb abductor of this utility model force detector, form by base plate 1, column 2, spring scale 3, lower limb cover 4, wherein said column 2 is fixed on the base plate 1, this column 2 is near base plate 1 one sides, described column 2 upper lateral are provided with spring scale 3, and these spring scale 3 flexible ends overlap 4 middle parts by belt and lower limb and link to each other.Described lower limb cover 4 be cylindric, and this lower limb overlaps that 4 upper ends are big, and the lower end is little, and the described lower limb 4 upper, middle and lower portions of overlapping are with an adjustable telescopic band 5 respectively, and described spring scale 3 is flexible holds the telescopic band 5 that overlaps 4 middle parts by belt and lower limb to be connected.Need the patient that measures behind the replacement of total hip, will wear in the lower limb cover 4, the patient makes great efforts to abduction, the flexible end of pulling spring scale 3, and institute pulls out the numeral that flexible end upward marks and will show, for recording patient's abduction muscular strength.
As shown in Figure 3, Figure 4, embodiment 2 is identical with embodiment 1, and different is the edge of this column 2 by base plate 1 right side.
Claims (2)
1, a kind of lower limb abductor force detector, it is characterized in that: form by base plate (1), column (2), spring scale (3), lower limb cover (4), wherein said column (2) is fixed on the base plate (1), this column (2) is near base plate (1) one side, described column (2) upper lateral is provided with spring scale (3), and the flexible end of this spring scale (3) links to each other with lower limb cover (4) middle part by belt.
2, according to the described lower limb abductor of claim 1 force detector, it is characterized in that: described lower limb cover (4) is for cylindric, this lower limb cover (4) upper end is big, the lower end is little, described lower limb cover (4) upper, middle and lower portion is with an adjustable telescopic band (5) respectively, and the flexible end of described spring scale (3) is connected by the telescopic band (5) of belt with lower limb cover (4) middle part.
