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%, Zn 2.4%, Nb 1%, Mn 0.7%, Ag 0.4%, Cr 0.25%, Ti 0.12%, Ba0.2%, Ce0.03%, and the balance is Cu. According to the above 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 temperature of the copper melt Drop to 1130°C and add other alloying element ingredients. After a uniform melt is formed, the ...

Abstract

The invention relates to a vaginal dilation blade for a vaginal speculum for the obstetrics and gynecology department. The vaginal dilation blade comprises an upper vaginal dilation blade body and a lower vaginal dilation blade body which are coordinated with each other, wherein the vaginal dilation blade bodies are made of copper alloy, and the surfaces, contacting with the vagina, of the vaginaldilation blade bodies are provided with treated surface layers. The vaginal dilation blade has the advantages that the nickel-alloy coating layers of the vaginal dilation blade are subjected to passivation and a pore sealing process, so that the surfaces of the nickel-alloy coating layers are smooth and easy to clean, the corrosion resistance of the nickel-alloy coating layers are increased effectively, the nickel-alloy coating layers are harmless when contacting with the epidermal tissue of a human body, and a certain antibacterial effect is achieved.

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 ...
