Problems solved by technology

[0002] At present, in the medical industry, some parts involved in medical devices (such as endoscopic cutting stapler and the base of the disposable nail box) are made of stainless steel, such as martensitic stainless steel or austenitic stainless steel. The current processing method They are all wire cutting, which leads to serious waste of materials and high cost. After wire cutting, CNC surface polishing is required, which takes a long time to process and low production efficiency in mass production.

Embodiment 1

[0022] Such as Figure 1 to Figure 4 Shown, the present invention is a kind of processing technology of martensitic stainless steel medical instrument part, comprises making medical instrument part 6 after carrying out cold-rolling treatment 9 passes to martensitic stainless steel disc circle 1 (being wire rod), in 9 passes The process of the second cold rolling treatment also includes annealing the martensitic stainless steel disc 1 for 5 times, and the rolling deformation rate of each cold rolling treatment is less than or equal to 60% compared with the previous cold rolling treatment; annealing The temperature is 800°C to 900°C. The speed of the stainless steel disc 1 passing through the rolling zone is V1, and the speed through the heat treatment zone is V2. In the heat treatment process, a tube furnace 5 is used, and the furnace length of the tube furnace 5 is 8-10m; 0m / min<V1<20m / min, 1m / min<V2<6m / min. The diameter of the disk 1 is 12±0.3 mm; the material of the disk ...

Embodiment 2

[0024] The difference from Example 1 is that after the last cold rolling process, the surface electrolytic treatment is carried out on the finished medical device parts, after electrolysis, it is cleaned, and after cleaning, it is air-dried. After electrolytic cleaning and air-drying, the medical device parts are soaked in After 10 hours in the liquid medicine, air-dry, and apply a layer of water-proof protective film on the surface of medical device parts after air-drying. Nano-robots for entering the human body to reach the lesion to destroy tumors are set in the corroded micropores on the surface of medical device parts.

Abstract

The invention discloses a processing technology of a martensitic stainless steel medical device part, which comprises the steps of cold-rolling a martensitic stainless steel disc for 9 passes to make a medical device part, during the 9-pass cold rolling process It includes annealing the martensitic stainless steel disc for 5 times, and the rolling deformation rate of each cold rolling treatment is less than or equal to 60% compared with the previous cold rolling treatment; the annealing temperature is 800°C to 900°C. The invention is used in the processing of medical device parts in the medical industry, which changes the previous process of CNC surface polishing after wire cutting, greatly reduces the processing time, improves production efficiency, and reduces production costs by half.

Description

technical field [0001] The invention relates to a processing technology of martensitic stainless steel medical device parts. Background technique [0002] At present, in the medical industry, some parts involved in medical devices (such as endoscopic cutting stapler and the base of the disposable nail box) are made of stainless steel, such as martensitic stainless steel or austenitic stainless steel. The current processing method Both are wire cutting, which leads to serious waste of materials and high cost, and after wire cutting, CNC surface polishing is required, which takes a long time for processing and low production efficiency in mass production. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art and provide a processing technology for martensitic stainless steel medical device parts, which is used for the processing of medical device parts in the medical industry. During the polishing process, the pr...
