Description

Technical Field

[0001] This utility model relates to the field of measuring rulers, and in particular to a sliding ruler for intraoperative orthopedic imaging measurement. Background Technology

[0002] In orthopedic surgery, surgeons typically need to know the relative relationships between various bony landmarks in intraoperative images. For example, in intraoperative images of hip replacement surgery, surgeons usually determine the horizontal height between the lesser trochanter and the ischial tuberosity by visual inspection; in scoliosis surgery, surgeons need to know the angle between the endplates of two vertebrae in the same radiographic image, and so on.

[0003] However, existing measuring rulers are single-plate instruments. Doctors need to use multiple measuring rulers in combination, and they need to place them on the radiographic image. When multiple measuring rulers are used together, it is inconvenient for doctors to handle and operate them, which can lead to inaccurate measurements. Therefore, we designed a sliding ruler for intraoperative orthopedic imaging measurement, which not only makes it easier for doctors to adjust the measuring ruler, but also integrates size measurement and angle measurement. Utility Model Content

[0004] In view of this, the present invention provides a sliding ruler for intraoperative orthopedic imaging measurement, which can solve the problem that when using conventional measuring rulers for intraoperative orthopedic radiographic imaging measurement, it is not convenient to use size measurement and angle measurement in combination, which leads to the problem that doctors cannot easily combine and adjust multiple measuring rulers, resulting in inaccurate measurements.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a sliding scale for intraoperative orthopedic imaging measurement, comprising a main scale, a suction cup fixedly connected to the outer wall of the main scale, and a scale strip on the front of the main scale; the main scale has a hollow structure and is divided into upper and lower sliding cavities by a partition; a first threaded rod is vertically provided in the upper sliding cavity, the first threaded rod is rotatably installed in the upper sliding cavity, its upper end extends out of the main scale, and a first knob is fixedly connected to its end; a second threaded rod is vertically provided in the lower sliding cavity, the second threaded rod is rotatably installed in the lower sliding cavity. Inside, the lower end of the main scale extends out and is fixedly connected to a second knob at the end; the main scale is provided with a first scale dial and a second scale dial on the outside, the first scale dial and the second scale dial are slidably connected to the main scale through an upper slider and a lower slider respectively, the upper slider and the lower slider are threadedly connected to a first threaded rod and a second threaded rod respectively through a threaded connecting sleeve; an upper auxiliary scale is rotatably connected inside the first scale dial, and a scale strip is provided on the outer wall of the upper auxiliary scale; a lower auxiliary scale is rotatably connected inside the second scale dial, and a scale strip is provided on the outer wall of the lower auxiliary scale.

[0006] The preferred technical solution of this utility model is as follows: the main ruler is a hollow frame structure formed by connecting the upper and lower ends of two ruler plates. The first threaded rod and the second threaded rod are arranged on the same straight line along the length of the main body, and the lower end of the first threaded rod is rotatably connected to the partition plate through the first rotating plate, and the upper end of the second threaded rod is rotatably connected to the partition plate through the second rotating plate.

[0007] The preferred technical solution of this utility model is as follows: two suction cups are provided, which are distributed at the upper and lower ends of the outer wall of the back of the main ruler.

[0008] The preferred technical solution of this utility model is as follows: the outer wall of the first scale dial is provided with a ring-shaped scale bar, and the outer wall of the second scale dial is provided with a ring-shaped scale bar.

[0009] By employing the above technical solution, this utility model has the following beneficial effects:

[0010] (1) By setting a main scale and two sets of adjustable auxiliary scales, the measurement of radiographic images in orthopedics can be facilitated. During the measurement process, the first and second knobs can be turned to drive the first and second threaded rods to rotate, thereby adjusting the upper and lower sliders. The positions of the upper and lower sliders can be adjusted according to the position of the bone image to be measured, and the bone image can be placed between the upper and lower sliders. The longitudinal dimension of the bone image can then be measured by combining the scale strip on the outer wall of the main scale, thus achieving the effect of easy adjustment and measurement.

[0011] (2) This utility model uses the lifting and lowering of the upper and lower sliders to drive the first and second scale dials to lift and adjust synchronously. By rotating the upper and lower scales and combining scale bar one and scale bar two, the angle of the bone marker line can be measured. At the same time, the scale bars on the outer wall of the upper and lower scales facilitate the measurement of the length of the bone marker line.

[0012] This invention combines a ruler and an angle measuring ruler into one unit. When making measurements, only one ruler is needed to conveniently measure the angle and length of bone marker lines, etc. The ruler is easy to adjust during the measurement process, ensuring the accuracy of the measurement.

[0022] Rotating the first knob 5 causes the first threaded rod 3 to rotate, and the upper slider 6 connected to the outer wall of the first threaded rod 3 will move up and down, thereby adjusting the upper slider 6 and the upper auxiliary ruler 13 on the upper slider 6 to move along the length direction of the main ruler 1; rotating the second knob 9 causes the second threaded rod 7 to rotate, and the lower slider 10 connected to the outer wall of the second threaded rod 7 will move up and down along the second screw rod 7, thereby adjusting the lower slider 10 and the lower auxiliary ruler 16 on the lower slider 10 to move along the length direction of the main ruler 1.

[0023] The embodiment provides a sliding scale for intraoperative orthopedic imaging measurement, with reference to... Figure 1-5 As shown, the main scale 1 is provided with a first scale dial 11 and a second scale dial 14 on its exterior. The first scale dial 11 and the second scale dial 14 are slidably connected to the main scale 1 via an upper slider 6 and a lower slider 10, respectively. The upper slider 6 and the lower slider 10 are threadedly connected to a first threaded rod 3 and a second threaded rod 7 via threaded connecting sleeves, respectively. A scale strip 12 is fixedly connected to the outer wall of the first scale dial 11. The first scale dial 11, in conjunction with the scale strip 12, can measure the angle of the bone marker line.

[0024] The working principle of this invention is as follows: In use, the main scale 1 is attached to the radiographic image display screen using two suction cups 17. The distance between the upper slider 6 and the lower slider 10 is adjusted according to the bone image to be measured. Rotating the first knob 5 and the second knob 9 drives the first threaded rod 3 and the second threaded rod 7 to rotate respectively. During this rotation, the upper slider 6 and the lower slider 10 are adjusted to move up and down, positioning them at the upper and lower ends of the bone image to be measured. The longitudinal dimension of the bone image can be determined by the scale lines on the outer wall of the main scale 1. Then, rotating the upper slider 6... The upper and lower auxiliary rulers 13 and 16 are rotated to be horizontal with the bone landmark line. The angles formed by the rotation of the upper and lower auxiliary rulers 13 and 16 with the first and second scale dials 11 and 14 respectively are used to determine the angle of the bone landmark line by observing the scale bar 12 and scale bar 15. The scale bars on the outer walls of the upper and lower auxiliary rulers 13 and 16 also facilitate the measurement of the length of the bone landmark line. This allows doctors to combine size and angle measurement during the measurement process. It is not only easy to adjust, but also solves the problem of the inconvenience of handling single ruler combinations in the existing technology, thus improving the measurement accuracy.
