Study Arms (2)
Full visibility vnotes group
EXPERIMENTALA suitable size of multi-channel vaginal sealing instrument was inserted from the vagina, pneumoperitoneum formed air pressure, and the vaginal dome was dilated and fully exposed. The dome was opened under laparoscopy, and an approach platform was established to complete the total hysterectomy.
Traditional vnotes group
EXPERIMENTALThe vaginal fornix and part of cervical ligaments were incised by vaginal operation, and an approach platform was established to complete hysterectomy.
Interventions
Vnotes surgery using fully visualised surgical instruments
Vnotes surgery using traditional surgical instruments
