Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a vaginal dilator device capable of quickly replacing consumables. Background Art

[0002] A vaginal dilator, commonly known as a speculum or dilator in medicine, is a medical device used in routine gynecological examinations, surgeries and other medical procedures. A vaginal dilator usually consists of an upper and lower leaf and a handle. Depending on the way the dilator is opened, it can be divided into a pivot type and a push-pull type. Vaginal dilators used for surgery are usually made of metal materials, while those used for general gynecological examinations are usually made of polystyrene, polypropylene and other materials.

[0003] Vaginal dilators are commonly used medical devices in gynecology and obstetrics. Existing vaginal dilators are usually disposable items with high costs. In particular, vaginal dilators are listed as low-value non-chargeable medical consumables, which means that hospitals' expenses in this regard cannot be compensated by corresponding charges, which greatly increases the financial pressure on hospitals. Therefore, the handheld part of the vaginal dilator has not been infected by bacteria, and discarding it will cause a waste of resources and fail to achieve resource conservation and utilization.
