Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a vaginal dilator. Background Art
[0002] The vaginal dilator is a commonly used medical device in the examination, diagnosis and treatment of gynecological diseases. The commonly used vaginal dilator includes a pair of expanders that cooperate with each other. The head ends of the pair of expanders are duck-billed and can be inserted into the vagina. After opening, they form an angle, which is kept open by a positioning device and used to stretch the vagina. The opening is kept at a certain angle by the positioning device on the vaginal dilator. The doctor can observe through the observation port formed at the connection of the expander, and the medical staff can observe from the observation port and perform subsequent treatment operations. However, in the existing intrauterine surgery, it is necessary to collect the effluent inside the uterine cavity as a sample for subsequent testing. The existing medical staff generally tie a gauze on the handle of the vaginal dilator for collection. However, this way of collecting gauze usually has the problem of loose binding causing the gauze to fall off, and the gauze binding method for collecting is blocked at the binding gauze position, which makes it inconvenient for medical staff to operate.
