Small blood vessel diameter measuring scale

Abstract

The invention discloses a small blood vessel diameter measuring scale, relating to the technical field of blood vessel measurement. The small blood vessel diameter measuring scale comprises a measuring scale body, wherein the length of the measuring scale body is 100mm, the width of the measuring scale body is 5mm, the thickness of the measuring scale body is 1.5mm, the measuring scale body is made of a stainless steel material, three levels of scales are arranged on the measuring scale body, the length of each first-level scale is 1.5mm, totally ten first-level scales are available, the intervals among the first-level scales are 1mm, the length of the second-level scale is 0.75mm, and one second-level scale is available, is positioned between the first first-level scale and the second first-level scale, and is 0.5mm away from each of the first-level scale and the second first-level scale; the length of each third-level scale is 0.3mm, the third-level scales are positioned between the first first-level scale and the second-level scale and between the second-level scale and the second first-level scale, totally eight third-level scales are available, the third-level scales are close to the first-level scales and the second-level scale, each third-level scale is 0.1mm away from the adjacent third-level scale, namely, the intervals among the adjacent third-level scales are 0.1mm. The small blood vessel diameter measuring scale is used for measuring small blood vessels, and can directly complete the measurement and reading under a lens, the operation can be completed through one-hand operation by one person, the small blood vessel diameter measuring scale is a stainless steel straight rule, has low requirements on the environment, and is convenient to clean and disinfect, and the influences of the external environment to the measurement are small.

Description

technical field [0001] The invention relates to a small blood vessel diameter measuring ruler, which belongs to the technical field of blood vessel measurement. Background technique [0002] In microsurgery, the judgment of vessel diameter (inner diameter or outer diameter) is more important, especially for small vessels with a diameter of about 1 mm. On the one hand, blood vessels with different diameters are very important in the selection of blood vessels, anastomosis technique, selection of anastomotic lines, and judgment of postoperative prognosis; on the other hand, accurate recording of blood vessel diameters is the key to the statistics, analysis, and induction of clinical data. [0003] Under the variable magnification surgical magnifying glass, it is difficult to judge and measure the diameter of small blood vessels. At present, the most commonly used method is to measure with a special vernier caliper, and then obtain the value through conversion. [0004] Measur...

Problems solved by technology

[0004] Measurement of small blood vessels with a special vernier caliper can achieve good measurement accuracy, but the biggest disadvantage is that the operation is cumbersome and clinical promotion is difficult

First of all, it requires not only the measurement under the microscope, but also the conversion of the reading under the eyes; second, the measuring ruler often needs to be operated by both hands, and the position of the blood vessel needs to be adjusted at the same time, which is difficult for one surgeon to complete, which greatly reduces the operability; Finally, this type of measuring ruler has higher requirements on the environment, and cleaning and disinfection have a greater impact on accuracy
