Description

Barrier type vaginal speculum

Technical Field

The utility model relates to the technical field of medical instruments for gynecological examination, in particular to a barrier type vaginal speculum.

Background

The vaginal speculum is a medical device used for vaginal speculum examination and auxiliary operation of vaginal operation.

When women are subjected to gynecological operation, the outer end of the vaginal speculum is a large labia and a small labia, the inner end of the vaginal speculum is a cervical orifice, the vagina is in a closed state in a natural state, the large labia and the small labia are spread by the vaginal speculum until the cervical orifice and a surrounding vaginal vault are exposed, and the internal side is moved back and checked, so that the condition of pathological changes of the cervix and each wall of the vagina is comprehensively observed, the original design of the vaginal speculum is divided into an upper leaf and a lower leaf like a duck bill, the rear side edge of the upper leaf and the lower leaf which are spread into the vagina is hollowed-out, the cervical and the side wall of the vagina can be clearly exposed, the condition of the front wall and the rear wall of the vagina can be comprehensively observed by rotating the vaginal speculum, and the vaginal speculum is mainly used as an operation auxiliary operation tool, and the operation which is usually required to be assisted by the vaginal speculum is artificial abortion operation, curettage operation, hysteroscope operation, hysteroscopy operation, intrauterine device placement/removal operation, hydrotubation, cervical ring physical therapy, cervical hysterectomy, and the like. However, in clinical practice, we have found that some patients, especially obese, proliferators, have extremely loose vaginal walls;

the prior vaginal speculum is opened to the state of maximum caliber, and the vaginal walls at two sides still protrude towards the center of the vagina, so that the cervix uteri can not be fully exposed, the operation field is shielded, and the operation is influenced. Especially when carrying out cervical annular electrotomy, because the cervical is shielded by the vaginal wall that relaxes to the protrusion in the vagina, the operation is difficult to operate smoothly, has still increased the risk of vaginal wall electric injury, and to above-mentioned condition, we propose a barrier type vaginal speculum.
