Cutting uterine manipulator based on fluid auxiliary means

Abstract

The cutting uterine manipulator based on the fluid auxiliary means comprises a uterine manipulator tube. The uterine manipulator tube is sequentially sleeved with a fixed handle, a uterine cutting knife and a uterine manipulator cup, the two ends of the uterine manipulator tube are sleeved with a balloon and a uterine manipulator tube handle respectively, and a fluid expansion mechanism is arranged in the uterine manipulator tube. A uterus lifting tube fixing mechanism, a uterus lifting cup position adjusting mechanism, a position indicating mechanism, a uterus cutting knife operating mechanism and a vaginal irrigation mechanism are arranged between the outer wall of the uterus lifting tube and the inner wall of the fixed handle, and an outer sleeve is further arranged on one side of the fixed handle. According to the cutting uterus manipulator based on the fluid auxiliary means, cutting can be automatically completed, cut tissue and the instrument can be brought out together, the operation time is shortened through the instrument, the operation efficiency is improved, and the operation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of fluid instruments, in particular to a cutting uterine lifter based on fluid auxiliary means. Background technique [0002] The uterine lifter is an instrument used for total hysterectomy or subtotal hysterectomy. With the assistance of laparoscope, the uterine lifter is inserted into the uterus through the vagina to adjust the position of the uterus. , injection of drugs and other operations, and the surgical steps of removing the uterus with the assistance of a uterine lifter. [0003] At present, in laparoscopic total hysterectomy, the lifting rod of the uterine lifter does not have a balloon. After the lifting rod is inserted into the uterus, the uterus is not stretched by the fluid-filled balloon, and the lifting rod is used to adjust the uterus. It is more difficult to adjust the uterus simply by using the uterine lifter, there will be a risk of puncturing the vagina and uterus, which will easily le...

Problems solved by technology

[0003] At present, in laparoscopic total hysterectomy, the lifting rod of the uterine lifter does not have a balloon. After the lifting rod is inserted into the uterus, the uterus is not stretched by the fluid-filled balloon, and the lifting rod is used to adjust the uterus. It is more difficult to adjust the uterus simply by using the uterine lifter, there will be a risk of puncturing the vagina and uterus, which will easily lead to the spread of cancer cells and cause immeasurable secondary damage to the patient; at the same time, the traditional uterine lifter is not equipped with fluid For the function of cleaning the vagina, cleaning surgical instruments need to be added separately, which increases the cost of the operation and the operation steps are cumbersome;

[0004] Furthermore, the traditional uterine lift has no cutting and washing functions, that is, the traditional cup-shaped uterine lift can only support and fix the uterus during hysterectomy, and can only separate the uterus from the required tissue when the active instrument electric knife separates the tissue. The function of opening the separation part cannot complete the cutting function by itself; in addition, the lifting cup of the traditional uterine lifter has no fixed function, the uterus cannot be accurately positioned during the operation, and it is easy to slide during cutting. After the uterus is removed, the uterus needs to be removed with surgical forceps. The resected part is not closed, and it is easy to cause cancer cells to spread
