Processing method and processing equipment of epidural anesthesia needle tube

Abstract

The invention relates to a processing method and processing equipment of an epidural anesthesia needle tube. The processing method of the epidural anesthesia needle tube comprises the following steps of (1) fixed-length cutting, (2) tube bending, (3) bevel connection cutting, (4) bevel connection sharpening, and (5) scale line manufacturing. The processing equipment of the epidural anesthesia needle tube comprises a tube bending fixture, a tube cutting fixture, a conductive grinding head and a needle storing fixture. According to the method and the equipment, with the adoption of special processing tools, the equipment is convenient to operate, time-saving, labor-saving and few in manufacturing procedures; with the adoption of electrolytic grinding, burrs can be washed away after subjected to electrolytic corrosion by an electrolytic solution through which direct current flows, and a processing surface is smooth and uniform; since a chemical corrosion method is adopted to form scale lines on the stainless steel needle tube or a stainless steel bar, the manufactured scale lines have smooth and bright surfaces, are clear, and are not faded easily; and a manufactured product is convenient to use.

Description

technical field [0001] The invention relates to a processing method of a medical device, in particular to a processing method of an epidural anesthesia needle tube and processing equipment thereof. Background technique [0002] At present, the processing technology of epidural anesthesia needles generally adopts a fixed wheel to bend into a certain radian, first cuts at a certain angle with a wire cutter, cleans the oil after cutting, then polishes and deburrs, and finally uses a marking machine to electrolyze method to make ticks. Another method is to use a certain wheel to bend it into a certain radian, first use a non-conductive grinding head to grind the pin, then perform sandblasting and electrolysis to remove burrs, and finally use a marking machine electrolysis method to make a scale. The above method of bending with a certain wheel (fixed and cannot be rotated), the bending arc will have traces of extrusion on the inner side, and it will be polished later. Wire cut...

Problems solved by technology

[0003] The present invention aims at the problems of cumbersome processing methods in the prior art, poor processing quality and inconvenient use, and provides an epidural anesthesia needle tube processing technology and processing equipment, which can make the bending arc of the needle tube smooth, and complete sharpening and deburring at one time. The procedure is reduced, thereby reducing the production cost, making the needle tube puncture convenient, and the catheter will not be damaged when passing through the catheter, so that the surface of the scale line made on the needle tube is smooth and shiny, the scale is clear, and it is not easy to fade, which is convenient for anesthesiologists in clinical practice.
