Problems solved by technology

[0004] The purpose of the present invention is to provide a lower limb orthopedic ruler, which solves the problem of repeated measurement when using a pen, a ruler and a protractor for preoperative measurement and line drawing in the diagnosis and treatment of the existing deformed bone orthopedic osteotomy. Time-consuming, large amount of line drawing, heavy workload, time-consuming, laborious, low-efficiency, pre-operative measurement and planning work, and even technical problems that delay the time of lower limb orthopedic surgery

Embodiment Construction

[0033] Examples see figure 1 As shown, a lower limb orthopedic ruler includes an orthopedic ruler template 1, and the orthopedic ruler template 1 is engraved with a vertical orthopedic ruler central axis 4, and the middle part of the orthopedic ruler central axis 4 is positioned at the midpoint of the knee joint platform line Holes 27, on the orthopedic ruler template 1, the midpoint positioning hole 27 of the knee joint platform line is used as a demarcation point, and a series of anatomical shaft grooves are carved up and down: there is an anatomical tibial shaft groove 6 vertically downward along the central axis 4 of the orthopedic ruler, There is an anatomical femoral shaft groove 5 obliquely upwards with the central axis 4 of the orthopedic ulnar, communicates with the anatomical femoral shaft groove 5 and has a femoral neck anatomical shaft groove 7 at an angle with the central axis of the groove; the top of the anatomical shaft groove 7 of the femoral neck has Joint ce...

Abstract

The invention discloses a lower limb orthopedic ruler which comprises an orthopedic ruler template, multiple wire slots such as an orthopedic ruler central axis, an anatomy axis slot and a joint walking line, as well as lower limb bone part angles, wherein an orthopedic ruler length scale and a protractor also can be marked on the orthopedic ruler template. Through the invention, a complicated CORA (center of rotation of angulation) line drawing method is simpler and easier to implement; the lower limb orthopedic ruler is convenient to use, adopts a standard template measurement mode, improves the working efficiency, shortens the preoperative preparation time, solves the problems that multiple times of repeated measurements are required in preoperative measurement and planning for the existing diagnosis treatment of the deformed bone orthopedic osteotomy surgery and consequently the line drawing workload is heavy, the time and labor are wasted and the efficiency is very low, and meets the needs of the diagnosis treatment of the deformed bone orthopedic surgery.

Description

technical field [0001] The invention relates to a preoperative measuring ruler for bone surgery, in particular to a template ruler used before deformed bone correction and osteotomy. Background technique [0002] Based on the Ilizarov technology system, Dror Paley and others in the United States created a preoperative analysis method for the quantitative expression of the mechanical axis, anatomical axis, and joint line of the lower limbs, referred to as CORA (Centre of Angled Rotation). Line-drawing analysis of limb deformities is used to determine osteotomy fixation and orthopedic methods, so that there will be no mistakes in treatment strategies. [0003] In the past, when the orthopedic surgery performed the diagnosis and treatment of deformed bone orthopedic osteotomy, doctors used the CORA method to measure and analyze the limb deformity before operation, so as to determine the osteotomy fixation and orthopedic method, and ensure the correctness of the deformed bone or...
