Description

Technical Field

[0001] This utility model relates to the field of adjustable vaginal speculum technology, and in particular to an adjustable vaginal speculum for obstetric and gynecological examinations. Background Technology

[0002] Gynecological examinations are the cornerstone of women's reproductive health management, spanning all stages of a woman's life, including puberty, reproductive years, and menopause. During puberty, they are used to screen for congenital reproductive system diseases, contributing to the healthy growth of young girls. During the reproductive years, they are related to pre-conception guidance, pregnancy monitoring, and postpartum recovery. During menopause, they focus on various symptoms caused by hormonal changes. Regular checkups can detect vaginitis, cervicitis, and ovarian cysts in a timely manner, giving doctors an early advantage in precise treatment. Hundreds of millions of women undergo routine gynecological examinations each year, highlighting their importance. As a key instrument in gynecological examinations, the speculum is responsible for opening the vagina and exposing the cervix and vaginal walls, providing doctors with direct visual information and laying the foundation for collecting cell samples. Doctors use it to accurately assess the condition of the vaginal mucosa, detect the presence of masses, or perform cervical smears, HPV testing, and biopsies. Its accurate and efficient use directly relates to diagnostic accuracy and the rationality of treatment plans.

[0003] Currently available vaginal speculums mainly consist of a handle, upper blade, and lower blade. The blades are inserted into the patient's body for examination. Traditional speculums largely rely on manual operation and experience-based judgment by doctors for adjustment. Different doctors have varying techniques and strengths, and their skill levels differ. Novice doctors often struggle with complex situations, spending considerable time trying to adjust the speculums, prolonging the examination and increasing patient discomfort. Even experienced doctors, under continuous high-intensity work, are prone to fatigue and errors, affecting the accuracy of adjustments. Furthermore, these speculums are often made of stainless steel, which is hard and lacks elasticity. This characteristic makes the speculum feel stiff during adjustment, requiring doctors to exert considerable force to open and close it. The rigid structure of metal speculums can also cause excessive pressure and friction on the vaginal soft tissue during adjustment, increasing patient pain and discomfort, and even triggering involuntary muscle contractions, interfering with the normal adjustment and examination process. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an adjustable vaginal speculum for obstetric and gynecological examinations. It aims to improve the existing technology where traditional vaginal speculum mostly rely on manual operation and experience judgment by doctors for adjustment.
