Abstract

The invention discloses a two-point discrimination measurer which comprises a measuring scale. A fixing measuring pin is arranged at a 0 scale end of the measuring scale, the tip of the fixing measuring pin and a 0 scale line of the measuring scale are positioned on the same straight line, a movable measuring pin capable of horizontally sliding along the measuring scale is arranged on the measuring scale, and the distance between the tip of the fixing measuring pin and the tip of the movable measuring pin is a two-point discrimination distance. By the mode, the two-point discrimination measurer is simple in structure, convenient to operate and more accurate in measuring result.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a two-point discrimination measuring device with simple structure, convenient operation and more accurate measurement results. Background technique [0002] In hand surgery disease, it is very common to measure the recovery of nerves by measuring the discrimination between two points on the skin. At present, the existing measurement methods often use a paper clip to measure, and then use a ruler to measure the distance between the two needle points, but often due to hand shaking and two measurements, errors in the measurement results are caused. Contents of the invention [0003] The technical problem mainly solved by the invention is to provide a two-point discrimination measuring device with simple structure, convenient operation and more accurate measurement results. [0004] In order to solve the above-mentioned technical problems, a technical solution...
