Description

A specialized form of vaginal speculum is the weighted speculum, which consists of a broad half tube which is bent at about a *0 degree angle, with the channel of the tube on the exterior side of the angle. One end of the tube has a roughly spherical metal weight surrounding the channel of the speculum. A weighted speculum is placed in the vagina during vaginal surgery with the patient in the lithotomic position. The weight holds the speculum in place and frees the surgeon\'s hands for other tasks. A vaginal speculum is also used in fertility treatments, particularly artificial insemination, and allows the vaginal cavity to be opened and observed thereby facilitating the deposit of semen into the vagina
