AI Technical Summary

Technical Problem

Existing uterine manipulators cannot effectively fix the cervix and vagina of postmenopausal women with cervical atrophy, which increases the difficulty of surgery and the risk of injury to the bladder, ureter, and rectum.

Method used

A novel uterine manipulator was designed, employing a suction cup and vertical rod structure. The suction cup is fixedly attached to the atrophied cervix and the anterior and posterior walls of the vaginal apex. The vertical rod contains a horizontal bar and a detachable uterine rod, which are used to open the spaces between the cervix, vagina, bladder, and rectum, reducing the difficulty of the surgery and minimizing the risk of injury.

Benefits of technology

The combination of suction cups and vertical rods effectively fixes the atrophied cervix and vagina, avoids gap folding, reduces surgical difficulty, and minimizes the risk of damage to the bladder, ureter, and rectum.

Abstract

The utility model relates to the technical field of medical auxiliary instruments, in particular to a novel uterine manipulator which is characterized by comprising a vertical rod and a sucker fixedly arranged at the top end of the vertical rod, the sucker and the vertical rod are coaxially arranged, and the sucker is used for being fixedly adsorbed to the atrophic cervix uteri and the front wall and the rear wall of the top vagina. The uterine manipulator can be used by a female patient with postmenopausal cervical atrophy, and can be fixedly adsorbed with the front wall and the rear wall of the atrophy cervix uteri and the front wall and the rear wall of the top end vagina through the suction cups, so that the atrophy cervix uteri and the top end of the vagina are fixed; gaps among the cervix uteri, the vagina, the bladder and the rectum can be fully expanded, and the risks that the operation difficulty is increased and the bladder, the ureter and the rectum are injured due to gap folding are avoided.
