Bearing-slide four-side adjustment coplanar molybdenum-alloy medical ruler

Abstract

The invention relates to a medical special measuring tool, namely a bearing-slide four-side adjustment coplanar molybdenum-alloy medical ruler. Improvements of the four-side adjustment coplanar molybdenum-alloy medical ruler are as follows: the lower surface of a sliding part is a sliding lower plane, a bearing pin shaft is arranged on the sliding lower plane, a rolling bearing is fixed on the bearing pin shaft, the upper surface of a scale part is a scale upper plane, a bearing slide is arranged on the scale upper plane, a transition groove is formed between the bearing slide and the scale upper plane, a blind groove space is formed in the bottom of the bearing slide, and one end of the bearing slide is opened; a split pin for a shaft is arranged at the outer end of the bearing pin shaft, is used for stopping the rolling bearing and is positioned in the blind groove space, and a space is formed between the split pin for the shaft and the blind groove space; the slide lower plane and the scale upper plane are located at the same height; a scale slope is arranged on the inner side of the scale upper plane, and the length scale is carved on the scale slope; the bearing slide on each ruler and the bearing slide on an adjacent ruler are in sliding fitting, so that different wounds of different sizes can be continuously and freely adjusted and measured.

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 molybdenum alloy medical scale for adjusting the four sides of a bearing slideway in 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 clinicians. X-ray i...

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 bearing slideway, and realizes that a variety of specifications with different sizes can share the four sides of the bearing slideway to adjust the same plane molybdenum alloy medical scale, so as to solve the problem of existing measuring rulers. Multiple measurements are required and it is easy to cause infection of the patient site
