Abstract

The invention relates to an automatic detection device for size of a used position of a surgical instrument and a detection method thereof. A video camera consists of a CMOS image sensor and a CMOS camera; the above of a detecting platform is fixedly connected with a helical-toothed upright post guide rail through a guide rail pedestal; a helical-toothed groove of the upright post guide rail is connected and fixed with a guide rail sliding block; the front of the guide rail sliding block is fixedly connected with a camera frame; the above of the camera frame is fixed with the video camera; the below of the video camera is fixed with a calibration gauge block fixture, the front of the calibration gauge block fixture is provided with a width detecting fixture, and the left side of the calibration gauge block fixture is provided with a height/thickness detecting fixture; an illuminator is placed on a platform under the video camera, and the center of a camera lens, the center of the calibration gauge block fixture, and the centers of the calibration gauge block and a detection position are in the same perpendicular line; and the video camera is connected with a computer through a USB 2.0 universal serial bus interface. The detection method comprises the following steps: 1, image acquisition; 2, system calibration; and 3, image processing, namely automatic positioning of the used position and edge detection of sub-pixel.

Description

technical field [0001] The invention relates to an instrument for automatically detecting the size of a used part of a surgical instrument, in particular to an automatic detection device and a detection method for the size of a used part of a surgical instrument based on the principle of machine vision. Background technique [0002] The size detection of surgical instruments is a very common and practical problem in the quality control of surgical instruments. At present, domestic surgical instrument manufacturers mainly adopt manual measurement methods, such as using vernier calipers, micrometers and other tools to measure the size of surgical instruments. This traditional manual visual inspection is time-consuming, labor-intensive and inefficient, and human error is inevitable. Contents of the invention [0003] The present invention is to provide an automatic detection device and detection method for the size of the used part of the surgical instrument. The device and ...
