Circular-slide-way aluminum oxide medical four-side same-plane measuring rule

Abstract

The invention relates to a circular-slide-way aluminum oxide medical four-side same-plane measuring rule. According to the improvement, a circular groove is formed in a lower sliding plane. A centrosymmetric transition groove is formed between the circular groove and the lower sliding plane. The upper surface of a scale part is an upper scale plane. A circular protruding rail is arranged on the upper scale plane. A centrosymmetric protruding strip is arranged between the circular protruding rail and the upper scale plane. Ball base step holes are formed in the lower sliding plane and symmetrically distributed on the two sides of the transition groove. A step hole plane is arranged on steps in the ball base step holes. A sliding rolling ball is fixed in the step hole plane. The inward protruding ball face, protruding out of the outer side face of a sliding ball base on a sliding ball base inner half piece, on the sliding ball is contained in a ball base technological hole. The outward protruding ball face of the sliding ball makes contact with the upper scale plane. The circular groove in each measuring ruler is in sliding fit with the circular protruding rail of an adjacent measuring ruler. The circular-slide-way aluminum oxide medical four-side same-plane measuring rule can be flexibly and easily adjusted to measure wounds of 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 medical measuring ruler with four sides and the same plane of aluminum oxide with a round slide. 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 is an...

Problems solved by technology

[0005] In view of the problems existing in the above prior art, the present invention adopts the design of adjusting the measuring tool with a circular groove slideway equipped with sliding balls, and realizes that a variety of specifications with different sizes can share the circular slideway aluminum oxide medical four-sided measuring scale on the same plane. In order to solve the problem that the existing measuring ruler needs to perform multiple measurements and is easy to cause infection of the patient's part
