Description

Orthopedic Curved Ruler for Easy Reading

technical field

The utility model relates to the technical field of medical instruments, in particular to an orthopedic curved measuring ruler which is convenient for reading.

Background technique

At present, many multi-functional rulers on the market are only satisfied with the functions of drawing, drawing lines and measuring. However, for medical measuring rulers, especially for orthopedics, most of them are limited to the measurement of joint range of motion, and there is no special X-ray for spine and joints. Orthopedic professional measuring ruler for spine and joint problems. Orthopedic problems such as the spine and joints are relatively complicated, and some diseases require doctors to carefully measure X-rays and observe the values accurately, so as to accurately judge the problem. Therefore, a more professional measuring ruler is needed to measure the spine and joints. Commonly used X-ray films and the range of motion of the spinal joints are used for measurement and evaluation.

For example, Chinese patent CN201320023613.8, the invention patent with the announcement date of December 04, 2013 discloses a multifunctional measuring ruler for orthopedic applications, especially for X-ray problems of spine, joints and other orthopedics and the range of motion of spinal joints Multifunctional measuring ruler for taking measurements. The measuring ruler is composed of a lower ruler and a first ruler, a left arc with a radius of 17cm, a right arc with a radius of 24cm, a full circular angle measuring ruler, a semicircular angle measuring ruler, and a rectangular ruler. The utility model improves the convenience of orthopedics measurement, but the measurement error in the aspect of spine or joint length is still relatively large and inconvenient.
