Definitions

  • the present invention relates to vaginal prosthetics, and more particularly to a vaginal dilatation rod.
  • Congenital vaginal disorders can be constructed by laparoscopic vaginoplasty.
  • Laparoscopic vaginoplasty requires freeing the peritoneum, then a vaginal tunnel, and then pulling the peritoneum into the vaginal tunnel and suturing the vestibule to cover the vaginal tunnel to form an artificial vagina.
  • the vaginal tunnel is formed mainly by the operator operating the dilatation blunt dilatation incision. Therefore, it is necessary to first make a small tunnel and then slowly expand to the desired size. Therefore, the current operation requires a variety of expansion rods, first with a small expansion rod for expansion, and then pulled out, replace the larger expansion rod, and so on, until the vaginal tunnel is formed.
  • the expansion rod is repeatedly pulled out, which easily leads to outflow of gas in the abdominal cavity, which causes the abdominal pressure to decrease and affects the operation field of the laparoscope.
  • pulling out the expansion rod can also cause the vaginal tunnel to collapse and easily cause false roads.
  • the present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention is required to provide a vaginal dilatation rod.
  • a vaginal dilating rod includes an inner rod and a cylindrical water jacket sleeved on the inner rod, the water bladder sleeve being adapted to expand under water injection to have different outer diameters of the vaginal dilatation rod.

  • the vaginal dilatation rod further includes a water injector for injecting water into the water bladder as needed.
  • the vaginal dilatation rod further comprises a body lubricant coated on the water bladder.
  • the water capsule is not filled with water or the water is injected less, so that the vaginal dilatation rod has a smaller size and the incision of the vaginal tunnel is expanded, and then the needle is not pulled out.
  • the water injection is gradually added, so that the vaginal dilatation rod gradually expands to the required size under the action of water injection, thereby avoiding the drop of abdominal pressure caused by the vaginal expansion rod and the formation of false roads.
