Description
Technical field
This utility model relates to technical field of medical instruments, particularly a kind of device for holding hip joint femoral stem.
Background technology
In replacement of total hip, femoral head height and femoral offset significant.Capital height is isometric very important for the two lower limb of maintenance, needs to measure the height on long axis of body of greater trochanter summit to late-segmental collapse to assess capital height in usual art.Femoral offset is too small may cause the severe complications such as dislocation of hip joint.Current hip joint holds position handle device not marking late-segmental collapse, femoral head height is measured at replacement of total hip if want, need to hold handle device to take off, the longitudinal axis of manual mark type femoral bone end prosthesis, thus obtain the relative altitude (i.e. femoral head height) on long axis of body on late-segmental collapse point and greater trochanter summit, operation technique is loaded down with trivial details, waste operating time.In addition, current hip joint is held without the special equipment measuring femoral offset on handle device, needs to hold handle device and take off during measurement, find late-segmental collapse position, then measure the horizontal range (i.e. femoral offset) of late-segmental collapse to greater trochanter summit, measurement is wasted time and energy, and error is larger.
Utility model content
In order to solve the deficiency of above-mentioned prior art, the purpose of this utility model is: provide a kind of device for holding hip joint femoral stem.
A kind of device for holding hip joint femoral stem, comprise and cylindricly hold handle 1, wherein, described cylindric handle 1 head of holding is hollow form, its side offers notch 2, and cylindricly hold the T-shape rule arranging in handle 1 head and be connected to form by cross bar 3 and montant 4 described, described montant 4 is provided with slidably vernier 5, fixing head 6 is set in described montant 4 side, is also provided with in described cylindric handle 1 inner portion of holding the draw-in groove 7 matched with described fixing head 6.
Described notch 2 length is greater than the length of described montant 4.
Described cross bar 3 and described montant 4 are all cuboid.
Described cross bar 3 and montant 4 are provided with scale.
Described vernier 5 is semi-annular shape, snaps onto on described montant 4.
Described cylindric cross section of holding handle 1 head is provided with the supporting plate 8 supporting described montant 4, and described supporting plate 8 exceeds the described cylindric end face holding handle 1 head.
When this utility model uses, the montant 4 of T-shape rule is placed on the cylindric head holding handle 1 along notch 2, the fixing head 6 of montant 4 is fitted and fixed with notch 2, completes the fixing of T-shape rule, the femoral head prosthesis of the model matched with hip joint is injected and needs to connect in the hip joint of limb, cylindric handle 1 head cover of holding of the present utility model is being plugged with capital hip joint top, guarantee that capital top is placed in vernier less than 5, adjustment cross bar 3, cross bar 3 is ridden over the A place, greater trochanter summit (the A point again greater trochanter of hip joint fixes a point to carry out labelling in advance) of hip joint, the scale value of vernier 5 top margin montant 4 is read from notch 2 side, the numerical value read adds the height value of vernier 5, add late-segmental collapse B place in radius of a circle value, the distance being exactly the greater trochanter summit A to late-segmental collapse B of hip joint is designated as numerical value I, the numerical value at the A place, greater trochanter summit of cross bar 3 hip joint deducts late-segmental collapse B place radius of a circle value, the greater trochanter summit A of hip joint is designated as numerical value II relative to the eccentric throw of long axis of body late-segmental collapse B point, the numerical value I recorded is contrasted with standard value, if the numerical value recorded I is greater than standard value, surely holds and cylindricly hold handle 1, slowly apply impulsive force from its top, the height of femoral head prosthesis is reach the required standards position, until the numerical value I recorded is consistent with standard value.
By test, the beneficial effects of the utility model are: structure is simple, convenient operation, the design of T-shape rule, structure is ingenious, and montant 4 realizes the measurement of the relative altitude of greater trochanter summit A on long axis of body to late-segmental collapse B point and hip joint, and cross bar 3 can record the distance of the greater trochanter summit A of late-segmental collapse B point and hip joint, namely the greater trochanter summit A of hip joint is relative to the eccentric throw of long axis of body late-segmental collapse B point, measures and accurately facilitates.
