DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides a technical solution: a uterine manipulator for hysterectomy, comprising a central guide rod 1, the central guide rod 1 is bent near its end, a central sleeve 2 is sleeved on the outer side of the central guide rod 1, and the central sleeve 2 is also bent near the bent position of the central guide rod 1. When in use, the uterine manipulator is held by medical staff, and the bent central guide rod 1 and the central sleeve 2 are easy to operate in surgery, and have the characteristics of simplicity and labor saving, and do not need to use the vaginal opening as a support point, thereby reducing the pressure on the vaginal opening.

[0024] A uterine lifting cup 5 is arranged on the side of the central guide rod 1, and the opening of the uterine lifting cup 5 is arranged away from the central sleeve 2, which is convenient for lifting the uterus after resection. The uterine lifting cup 5 is connected to the end of the central sleeve 2 through a fixing part. The uterine lifting cup 5 is arranged in a horn shape as a whole, which is convenient for assisting the removal of the uterus after resection from the vagina. A positioning plate 3 is fixed to the end of the central sleeve 2, and a threaded column 6 is fixed to the side of the uterine lifting cup 5. The fixing part includes a nut 4 slidably arranged on the outside of the central sleeve 2, and the nut 4 is adaptably connected to the threaded column 6. The nut 4 is connected to the threaded column 6, and the uterine lifting cup 5 is fixed to the positioning plate 3 at the end of the central sleeve 2, which is convenient for positioning and use of the uterine lifting cup 5.

[0025] A first capsule 9 is arranged on the inner side of the uterine lifting cup 5, and the first capsule 9 is arranged in an annular shape. An air guide tube 10 connected with the inner cavity of the first capsule 9 is installed on the side of the first capsule 9. One end of the air guide tube 10 away from the first capsule 9 passes through and extends to the outside of the uterine lifting cup 5, and a connector is installed on the end of the air guide tube 10, and the air guide tube 10 is connected with an external air pumping component through the connector. When the uterine lifting cup 5 lifts the uterus, air is pumped into the air guide tube 10 through the air pumping component to expand the first capsule 9. After the annular first capsule 9 is expanded, it wraps around the outside of the uterus to position the uterus in the uterine lifting cup 5, thereby improving the fixing strength of the uterine lifting cup 5 to the uterus, preventing the uterus from falling off during the removal process, and facilitating the removal of the removed uterus through the vagina.

[0026] A plurality of elastic plates 7 are arranged on the inner side of the uterine lifting cup 5, and a first sac 9 is located between the elastic plates 7 and the uterine lifting cup 5.
