Chromium alloy medical measuring tool with four adjustable and coplanar sides of circular slide rails

Abstract

The invention relates to a special medical measuring tool, and discloses a chromium alloy medical measuring tool with four adjustable and coplanar sides of circular slide rails. The chromium alloy medical measuring tool comprises a first measuring ruler, a second measuring ruler, a third measuring ruler and a fourth measuring ruler which have identical structure sizes. The chromium alloy medical measuring tool is characterized in that each sliding portion is positioned at an end of a corresponding scale portion and is higher than an upper plane of the scale portion; lower sliding planes are arranged on the lower surfaces of the sliding portions, circular grooves are formed in the lower sliding planes, central symmetry transition grooves are formed in positions between the circular grooves and the lower sliding planes, upper scale planes are arranged on the upper surfaces of the scale portions, circular convex grooves are formed in the upper scale planes, and central symmetry transition convex strips are arranged between the circular convex grooves and the upper scale planes; the lower sliding planes and the upper scale planes are positioned at the same altitude; scale slopes are arranged on the inner sides of the upper scale planes, and length scales are further engraved on the scale slopes; the circular convex groove in each measuring rule is in slide fit with the circular groove in the corresponding adjacent measuring ruler. The chromium alloy medical measuring tool has the advantage that the chromium alloy medical measuring tool can be continuously optionally adjusted for measuring wound with different sizes and areas.

Description

technical field [0001] The invention relates to a special measuring tool for medicine, and the international patent classification is A61B5 / 107, in particular to a chromium alloy medical measuring tool with four sides of a smooth track that can be adjusted on the same plane. Background technique [0002] In medicine, due to the needs of diagnosis, treatment or nursing, it is required to accurately measure the shape and size of incisions, wounds, pressure sores, ecchymosis, induration, etc. on the patient's body. Estimated measurement, such measurement is inaccurate, and it is easy to make the wound infected with germs. Therefore, how to solve these problems has become a problem to be solved urgently. [0003] For example: distal radius fracture is one of the common upper limb fractures, accounting for about 15.7% of upper limb fractures. Due to the importance of wrist joint function, the reduction and recovery of its displacement degree has always been valued by clinician...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the above existing problems in the prior art, the present invention adopts the design of adjusting the measuring tool by the smooth track, and realizes that a variety of specifications with different sizes can share the four sides of the smooth track, which can be adjusted on the same plane as the chromium alloy medical measuring tool, so as to solve the needs of the existing measuring ruler. Perform multiple measurements and easily cause infection of the patient site
