A kind of cutting and lifting device based on fluid auxiliary means

Abstract

The invention discloses a uterine cutting device based on fluid auxiliary means, which includes a uterine lifting tube, and a fixed handle, a uterine cutting knife and a uterine lifting cup are sequentially set on the outside of the uterine lifting tube, and the two uterine lifting tubes A balloon and a handle for lifting the uterine tube are respectively sleeved on the ends of the uterine lifting tube. A fluid expansion mechanism is arranged inside the uterine lifting tube. A fixing mechanism for the uterine lifting tube and a position for lifting the uterine cup are arranged between the outer wall of the uterine lifting tube and the inner wall of the fixed handle. An adjustment mechanism, a position indicating mechanism, a hysterectomy knife operating mechanism, a vaginal flushing mechanism, and an outer tube is arranged on one side of the fixed handle. A cutting uterine lifter based on fluid-assisted means disclosed by the invention can independently complete the cutting and bring out the cut tissue together with the instrument. The instrument shortens the operation time, improves the operation efficiency, and reduces the operation cost.

Description

technical field [0001] The invention relates to the technical field of fluid instruments, in particular to a cutting and lifting device based on fluid auxiliary means. Background technique [0002] The uterine lifting device is an instrument used for total hysterectomy or subtotal hysterectomy. Specifically, the uterine lifting device is inserted into the uterus through the vagina with the assistance of laparoscope to adjust the orientation of the uterus. , injecting drugs and other operations, and removing the uterus with the aid of a uterine apparatus. [0003] At present, in laparoscopic total hysterectomy, the uterus lifting rod of the uterine lifting device does not have a balloon. After the palace lifting rod extends into the uterus, the uterus is not stretched by the fluid-filled balloon, and the uterine lifting rod is used to adjust the uterus. It is more difficult to adjust the uterus by simply using the uterus lifting rod, which may cause the risk of puncturing th...

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
