The malformation of the back of the razor not only affects the appearance of the patient with scoliosis deformity of the thoracic vertebra, but also causes back pain and respiratory function limitation of the patient, and leads to self-inferior feeling and psychological disorder. In order to improve the appearance and the lung function, patients with serious razor back deformity need surgical correction, namely, the height difference of the bilateral backs of the razor back deformity is more than 3cm, and a thoracoplasty is needed. The current methods for measuring the dorsal deformity of the thoracic spine scoliosis razor mainly comprise the following three methods: the first method is a back surface measurement, which is a measurement of the height of the back of the razor directly using a ruler, using the shoulder blade line on the opposite side of the back of the razor as a reference horizontal position. The second method is to measure the height of the humped rib on the X-ray film at the 90-degree bend position of the patient with the humped contralateral rib as the baseline. The third method is to take the standard position of the patient's lateral spine X-ray film and measure the distance between the convex and concave peaks of the ribs.

According to an embodiment of the present invention, an orthopedic medical measuring device may include a base plate 100, a level gauge 200, a support rod 300, and two measuring scales 400. The front surface of the substrate 100 may be provided with a first indication scale 110. A level 200 may be provided on the substrate 100 to indicate whether the front surface of the substrate 100 is level. The supporting bar 300 may be disposed at the middle of the rear surface of the substrate 100 and extend in a direction away from the rear surface of the substrate 100. Preferably, the level gauge 200 may be provided in a middle region of the front surface of the base plate 100, thereby allowing medical staff to more easily view when adjusting the support bar 300, and thus to find the horizontal position more quickly. Preferably, each measuring ruler 400 may be provided with a second indicating scale 430. Each of the measuring sticks 400 may be provided on the substrate 100 in a manner to be slidable relative to the substrate 100. For example, the substrate 100 may be provided with a chute 120. The measuring tape 400 can be disposed in the sliding block 520 slidably engaged with the sliding groove 120. The slider 520 may be provided with a slide hole. The measuring ruler 400 can be inserted into the slide hole in a sliding way. The two measuring sticks 400 may be spaced apart from each other on either side of the support rod 300. For example, referring to fig. 1, a first measuring ruler 410 and a second measuring ruler 420 of the two measuring rulers 400 are respectively arranged at two sides of the support rod 300. In the measurement, a lateral distance of the measuring scale 400 with respect to the support rod 300 is indicated by the first indication scale 110, and a longitudinal distance of one end of the measuring scale 400 with respect to the base plate 100 is indicated by the second indication scale 430 on the measuring scale 400. When the medical staff uses the orthopedic medical measuring device of the embodiment, the operation process can be as follows: firstly, a patient lies on the bed, one end of the supporting rod 300 far away from the base plate 100 is abutted against the vertebra of the patient, the base plate 100 is adjusted to the horizontal posture, one measuring scale 400 is transversely slid to the rib bulge to be measured, the transverse distance of the measuring scale 400 relative to the supporting rod 300 is observed, then the other measuring scale 400 is adjusted to the same transverse distance relative to the supporting rod 300, the reading measured by the second graduated scale of the two measuring scales is read (the longitudinal distance of one end of the measuring scale relative to the base plate 100 is indicated), and the height difference of two positions to be measured on the body surface of the patient is calculated. The medical staff can know the rib deformity of the patient according to the transverse distance and the height difference and can be used as reference information for making a surgical plan. The medical staff can adjust the position of the end of the support rod 300 far away from the base plate 100 against the vertebra of the patient, and repeatedly measure the data of other positions of the body surfaces by the same principle so as to obtain more reference information. The technical scheme of the embodiment can at least realize the following beneficial technical effects: the utility model has simple structure, low cost and easy maintenance, is easier for the medical care personnel to operate than the prior art, and can intuitively measure the required reference information faster.
Preferably, the middle of the first indicating scale 110 is zero scale, and the scale values symmetrically increase from the middle to both sides, and the schematic structure is shown in fig. 2.
Preferably, the level 200 may be an existing mechanical or electronic level. The mechanical level may be, for example, a bar-shaped level as shown in fig. 1, or a round level as shown in fig. 3.
According to one embodiment of the utility model, the orthopedic medical measuring device is used as shown in fig. 4. The medical staff abuts the distal end of the support rod 300 against the spinous process of the spine, then moves one measuring ruler to the high point of the protrusion of the dorsal razor dorsal deformity, i.e. the position shown on the right side of fig. 4, observes the first indicating scale to obtain the lateral displacement of the measuring ruler, then moves the other measuring ruler in the opposite direction by the same lateral displacement on the other side of the support rod, and respectively reads the vertical readings on the two measuring rulers, from which the first target value D1 and the second target value D2 can be obtained. The first target value D1 is the height difference between the high point at the bulge of the back deformity of the razor relative to the spinous process of the spine. The second target value D2 is the difference in height at the spinal spinous process relative to a point of symmetry of the high point at the bulge of the back deformity of the razor. The first target value D1 and the second target value D2 may be used by medical personnel to understand the extent of the patient's razor back deformity prior to performing an operation in order to take a corresponding treatment regimen. The reading of the second indicating scale on the measuring scale 400 may also have various configurations. For example, referring to figure 5, a first arrangement is for the second indicating scale to be read progressively increasing from one end of the measuring scale to the other. Preferably, the size of the measuring scale is gradually increased from one end of the measuring scale, which is positioned at the same side with the supporting rod, to the other end of the measuring scale. In this arrangement, the predetermined distance (e.g., 100 mm) from one end of the support rod to the base plate is obtained in advance, and D1 and D2 can be calculated as follows: d1= vertical reading of the first measuring ruler 410-preset distance; d2= preset distance — vertical reading of the second measuring ruler 420. For another example, referring to FIG. 6, a second arrangement is where the reading of the second indicating scale increases from the middle of the measuring tape towards the ends. I.e. zero scale in the middle of the measuring scale. And the distance from the zero scale of the measuring scale to one end of the measuring scale on the same side with the support rod is equal to or approximately equal to the distance from the back surface of the substrate to the far end of the support rod. In this case, the thickness of the substrate 100 can be set as small as possible to reduce the influence on the reading. Thus, the medical professional may directly read the vertical reading of the first measuring scale 410 moving downward as the first target value D1 and read the vertical reading of the second measuring scale 420 moving upward as the first target value D2. The second arrangement is particularly preferred in the present invention in order to more quickly obtain the desired values of D1 and D2 without having to go through scaling.
In the previous embodiment, the two measuring sticks 400 slide independently of each other, and in order to measure two points, the two measuring sticks need to be moved in two separate steps. And actually, the purpose of the two measuring sticks 400 is to measure the height difference of the symmetrical points at the same distance from the support stick 300, so that the above embodiment can be further modified to perform the measurement more rapidly.
According to an embodiment of the present invention, referring to fig. 7, two measuring sticks 400 may be provided on the linkage 500, so that the two measuring sticks 400 are moved away from or close to the supporting rod 300 together with the same moving amplitude by the control of the linkage 500. The technical scheme of the embodiment can at least realize the following beneficial technical effects: through link gear 500, medical personnel can only realize adjusting two dipperstick 400 to symmetrical horizontal position through adjusting once and adjust, and the medical personnel operation of being more convenient for avoids having the position asymmetry that link gear 500 leads to and repeated the regulation, has alleviateed medical personnel's intensity of labour to, position control also can be more accurate, thereby obtains more accurate result.
