Abstract

The invention discloses a needle tip angle detector and a detection method. The needle tip angle detector comprises a base, a laser generator, a needle seat, and an angle projection plate. The laser generator, the needle seat, and the angle projection plate are sequentially arranged on the base in a straight line. The laser generator is provided with a laser outlet near the needle seat side. The laser outlet is flush with the top of the needle seat. The needle seat has a position adjuster at its base and two supporting rods at its top. The supporting rod is arranged perpendicular to the laseroutlet. Wafers perpendicular to the supporting rod are arranged on the surface of the two supporting rods in a staggered manner. The two supporting rods are rotationally fixed on the needle base. Thesemi-circular angle projection plate is provided with a scale. The scale zero of the scale of the angle projection plate is at the center of the semi-circular. The middle of the scale zero, the central line of the supporting rod of the needle seat, and the laser outlet are arranged on the same horizontal line. According to the needle tip angle detector and the detection method, the detector measures quickly and accurately, can visually and accurately detect the angle of the needle tip, and does not need to be limited by the working environment of the production workshop.

Description

technical field [0001] The invention relates to the field of medical equipment processing and detection, in particular to a needle tip angle detector and a detection method. Background technique [0002] When processing medical needles, the angle of the needle tip is an important basis for evaluating whether the needle is qualified: the different angles of the needle tip mainly affect the pain degree of the patient when the needle tip penetrates the skin. In order to ensure the quality of the needle point, usually, the angle of the needle point will be strictly controlled during the processing of the needle point. [0003] Usually, when producing and processing the needle point, the angle of the needle point is generally measured manually through a magnifying glass or a microscope, or the image of the needle point is input into a computer through a camera, and the measurement is performed through computer software. This method is very complicated and not intuitive enough, a...
