Technical Field
[0001] This utility model relates to the field of medical device technology, specifically a novel expander. Background Technology
[0002] Disposable vaginal speculum is commonly used in clinical gynecological examinations or surgeries. After the doctor places it in the patient's vagina and opens the entire clamp, he then uses an examination light or instrument to assist in the examination. When a lesion is found, smoke and body fluid will be generated in the vaginal cavity during the surgical procedure.
[0003] Existing dilators can achieve functions such as dilation, smoke removal, and fluid drainage, but they still have defects in use, which affect the convenient operation of medical staff. When using a dilator, the inside of the vagina is dark, and external lighting equipment is required to shine inward. Therefore, the refraction of light cannot accurately target the surgical site. At the same time, the adjustment of traditional dilators generally uses bolt rotation to control opening and closing, but the operation speed is slow and it is not convenient to press and lock in place to improve portability.
