Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a laterally expandable vaginal dilator and a method of using the same. Background Art

[0002] A vaginodilator can also be called a vaginal dilator. According to different opening methods, it can be divided into two types: pivot type and push-pull type. It is mainly used for routine gynecological examinations and is usually used in conjunction with a colposcope. It requires the use of an external light source for observation, shooting and image acquisition.

[0003] The vaginal dilator needs to be used with a suitable light source. Existing vaginal dilators usually need to use an external light source during use, which is inconvenient to use. In addition, there are vaginal dilators with built-in light sources on the market. The light source carried by such vaginal dilators is usually installed in a fixed position, and the brightness of the light source is set. During operation, the light source is easily blocked to produce shadows, resulting in the user being unable to clearly observe the secretions or pathological substances in the vagina. The vaginal dilators currently on the market are generally composed of upper and lower pages and a handle, which cannot achieve lateral expansion, and have poor visibility and accessibility. After the dilator is expanded, the expansion plate needs to be kept stable and cannot be locked with one hand, which requires high professional ability of the operator. Summary of the invention
