Embodiment 1

[0033] A vagina-expanding blade for an obstetrics and gynecology speculum device and a manufacturing method thereof. The vagina-expanding blade is divided into upper and lower pieces, and the upper and lower two vagina-expanding blades cooperate with each other. The main body of the vagina-expanding blade is made of copper alloy. The genital contact surface is provided with a surface treatment layer,

[0034] The preparation method of the shade expansion blade comprises the following steps: the mass percentage of copper alloy elements is: Fe 13%, Zn2.4%, Nb1%, Mn0.7%, Ag0.4%, Cr0.25%, Ti0.12% , Ba0.2%, Ce0.03%, and the balance is Cu. According to the above-mentioned chemical composition of the copper alloy, the copper ingots are first added to the melting furnace, and the furnace temperature is controlled at 1200 ° C. After the copper ingots are melted, the copper melt The temperature drops to 1130°C and other alloying element ingredients are added. After a uniform melt is for...

Abstract

A vagina-expanding blade for an obstetrics and gynecology speculum. The vagina-expanding blade is divided into upper and lower pieces, and the upper and lower two pieces of the vagina-expanding blade cooperate. The main body of the vagina-expanding blade is made of copper alloy. The surface treatment layer, the nickel alloy coating layer of the present invention is passivated and sealed after the surface is smooth and easy to clean, the corrosion resistance is effectively improved, there is no harm in contact with human epidermis, and it has a certain antibacterial effect.

Description

technical field [0001] The invention relates to a vagina-expanding blade for a vaginal speculum used in obstetrics and gynecology, and belongs to the field of medical instruments. Background technique [0002] Most of the examination and treatment of gynecological diseases need the assistance of endoscopes, and the lesions need to be clearly observed for symptomatic treatment. During the treatment process, flushing treatment, drug treatment, red light treatment with instrument irradiation, drug atomization treatment and surgical operation are all necessary. An endoscope needs to be applied. Oxidative corrosion occurs after long-term use of the existing speculum, and corrosion pits are easy to appear on the surface after corrosion. When washing, it is very difficult to clean the corrosion area, which is not conducive to effectively eliminating bacteria and stolen goods. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the method ...
