Abstract
Description
Technical Field
[0001] This invention relates to the field of medical testing technology, and more specifically, to an angle measurement tool for spinal imaging assessment. Background Technology
[0002] Scoliosis is a common spinal disorder. Depending on the cause, it can be divided into idiopathic scoliosis, congenital scoliosis, and degenerative scoliosis. The degree of scoliosis usually requires spinal imaging.
[0003] Angles involved in spinal imaging have significant clinical reference value. For example, the severity of scoliosis is assessed by the size of the Cobb angle, the lumbosacral angle is an important indicator of lower lumbar spine stability, and there are also lumbar spondylolisthesis angle and sacral tilt angle, etc.
[0004] The measuring tools used in the existing technology are mainly for measuring and examining individual parts, such as scoliosis, uneven shoulders, the lower edge of the scapula, and the level of the iliac bone. Moreover, only scoliosis has a scoliosis measuring ruler. Other measurements are mainly based on visual estimation, which lacks accurate angles and precise positioning, and is prone to problems such as unclear standards or large deviations.
[0005] Therefore, there is an urgent need to design an angle measurement tool for spinal imaging assessment. Summary of the Invention
[0006] To overcome the aforementioned deficiencies in existing technologies, this invention provides an angle measurement tool for spinal imaging assessment. This tool can be applied not only to preliminary screening but also to the measurement of full-spine X-rays. It utilizes surface landmarks for precise positioning and measurement, measuring the balance of key body parts such as the spine, shoulders, scapula, and patella. This solves the problem of positioning ambiguity caused by changes in body position, reduces the tedious procedures of multiple markings and measurements by doctors, significantly improves doctors' work efficiency and patient compliance, and reduces the workload of doctors.
[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an angle measurement tool for spinal imaging assessment, comprising a vertical rod, a U-shaped component 1 at the top of one side of the vertical rod, a locking block 1 on the inner side of each of the two clamping pieces of the U-shaped component 1, and locking grooves for the locking blocks 1 to be engaged on both sides of the top of the vertical rod; the vertical rod is provided with two U-shaped components 2, the two U-shaped components 2 being located on the same side of the vertical rod as the U-shaped component 1, the U-shaped components 2 being slidable along the length direction of the vertical rod, the locking blocks 2 being provided on the inner side of each of the two clamping pieces of the U-shaped component 2, and sliding grooves for the locking blocks 2 to be engaged on both sides of the vertical rod along the length direction of the vertical rod; a horizontal rod 1 is provided on the side of the U-shaped component 1 away from the vertical rod, the horizontal rod 1 being... An angle adjustment mechanism is provided between the U-shaped parts. The angle adjustment mechanism includes a circular plate 1, a circular plate 2, a connecting post 1 located between the circular plate 1 and the circular plate 2, and a rotating plate 1 sleeved on the outer wall of the connecting post 1. There are two crossbars 1, which are located at both ends of the rotating plate 1. A crossbar 2 is provided on the side of the U-shaped part 2 away from the vertical bar. An angle adjustment mechanism 2 is provided between the crossbar 2 and the U-shaped part 2. The angle adjustment mechanism 2 includes a circular plate 3, a circular plate 4, a connecting post 2 located between the circular plate 3 and the circular plate 4, and a rotating plate 2 sleeved on the outer wall of the connecting post 2. There are two crossbars 2, which are located at both ends of the rotating plate 2. The top surfaces of the circular plate 2 and the circular plate 4 are provided with scale lines set along the circumference of the circular plate 4.
[0008] By adopting the above technical solution, the second card block can slide in the groove, that is, the second horizontal bar can move along the length of the vertical bar, which can be applied to human spinal images of different body sizes, and the angle between the horizontal bar and the vertical bar can be changed by the angle adjustment mechanism.
[0009] Furthermore, the vertical rod has a strip groove along its length, and the side of the vertical rod facing the U-shaped part has a notch along its length, which is connected to the strip groove. The vertical rod has a rotating rod with one end extending into the strip groove, and the other end of the rotating rod passes through the notch, circular plate three, connecting column two, and circular plate four in sequence. The end of the rotating rod extending into the strip groove is equipped with a gear, and a rack that meshes with the gear is provided on one side wall of the strip groove. The end of the rotating rod that passes out of circular plate four is equipped with a handle.
[0010] By adopting the above technical solution, when it is necessary to adjust the position of the second horizontal bar on the vertical bar, the horizontal bar can be moved along the length of the vertical bar by rotating the handle and the gear meshing with the rack.
[0011] Furthermore, neither the first horizontal bar nor the two second horizontal bars are on the same vertical plane.
[0012] By adopting the above technical solution, the first horizontal bar and the two second horizontal bars are set at different positions on the first and second rotating plates, so that the three are not on the same vertical plane, allowing them to overlap when measuring angles, which is convenient for use.
[0013] Furthermore, the side of the crossbar one near the circular plate two is provided with a pointer line one arranged along the length direction of the crossbar one, and the side of the crossbar two near the circular plate four is provided with a pointer line two arranged along the length direction of the crossbar two.
[0014] By adopting the above technical solution and setting pointer line one and pointer line two as pointers, observation is facilitated.
[0015] Furthermore, a magnet is provided on the side of the second circular plate facing the first rotating plate, and a magnet is provided on the side of the first rotating plate facing the second circular plate; a magnet is provided on the side of the fourth circular plate facing the second rotating plate, and a magnet is provided on the side of the second rotating plate facing the fourth circular plate.
[0016] By adopting the above technical solution, magnet one and magnet two attract each other, and magnet three and magnet four attract each other, which facilitates the reset of the crossbar after angle measurement, and the crossbar is aligned with the zero line of the scale after reset.
[0017] In summary, the present invention has the following beneficial effects: The present invention can be applied not only to preliminary screening, but also to the measurement of whole spine X-rays. It uses human body surface landmarks for precise positioning and measurement, and measures the balance of major human body parts such as the spine, shoulders, scapula, and patella. It can solve the problem of positioning ambiguity caused by changes in body position, reduce the tedious procedures of doctors drawing lines and measuring multiple times, greatly improve doctors' work efficiency and patients' compliance, and reduce doctors' workload.

There are two crossbars 2 13, which are located at the two ends of the rotating plate 2 17 respectively. The top surfaces of the circular plate 2 10 and the circular plate 4 15 are engraved with scale lines 18 set along the circumference of the circular plate 4 15.
[0028] The vertical rod 1 has a strip groove 19 extending along its length. The side of the vertical rod 1 facing the U-shaped part has a notch 20 extending along its length, which is connected to the strip groove 19.

[0032] Working principle: The upright bar 1 is used to locate the spine and measure whether the spinal curvature has pathological curvature. The horizontal bar 8 can measure the Cobb angle. The horizontal bar 13, which is close to the horizontal bar 8, can be adjusted according to the height of the human body to measure the lower edge of the scapula. The other horizontal bar 13 can be adjusted to be level with the iliac bone. All three horizontal bars can be rotated up and down to adjust the angle, and the corresponding examination data can be given through angle screening.
