Inner hole threading type medical anchor machining process

Abstract

The invention provides an inner hole threading type medical anchor machining process. The method is mainly used for processing a medical anchor with a complex structure. The medical anchor is processed by the following steps of: (1) selecting materials; (2) primarily processing the raw materials; (3) secondary processing of the raw materials; (4) processing and forming the materials; (5) performing stress treatment; (6) performing polishing treatment; (7) performing coating processing; and (8) air-drying and packaging the product. Through various processing of the process, the overall performance of the medical anchor with the loaded internal structure is enhanced, the overall strength of the medical anchor during use is ensured, and meanwhile, the coating effect of the surface layer of the anchor is also ensured, so that the coating is completely consumed after the anchor can be kept in a human body for enough time; therefore, the overall use effect of the anchor is ensured.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical anchor. Background technique [0002] People often encounter tendon or ligament injuries during sports. When the tendon or ligament is seriously injured, such as sharp cutting or violent pulling, it will break neatly. Avulsion fractures; traditional medical repair methods are often used, such as plaster or bandage external fixation, steel wire suture, suture suture, tendon prevention after bone opening, etc. These traditional methods are not firm, If it takes a long time and the curative effect is not good, it will also cause joint adhesion, stiffness and other conditions, and even the tissue will break again, resulting in residual pain at the trauma site and even partial loss of function. Traditional medical anchors are usually connected to the tension wire at the rear, which bears low tension during use, and it is easy to pull off the rear of the anchor. In a...

At this time, hydrofluoric acid has no fluidity. When the anchor is coated, the concentration of hydrofluoric acid around the anchor will be reduced after the surrounding hydrofluoric acid is consumed, which greatly affects the coating formation of the anchor, making the coating It is thinner, and the temperature of the hydrofluoric acid solution will change during the coating process when the traditional hydrofluoric acid is used for coating, which will affect the effect of the entire coating.

For anchors with a cavity and an opening structure in the middle, the traditional coating process has poor processing effects, and it is difficult to meet the requirements for the use of medical anchors.
