Multifunctional uterine manipulator

Abstract

The invention relates to the technical field of uterine manipulators, in particular to a multifunctional uterine manipulator. The multifunctional uterine manipulator is structurally characterized in that a central guide rod is of a hollow core structure, and a perforation preventing device is arranged at the top end of the central guide rod; an anti-falling device is located in a groove formed inthe upper part of the central guide rod, a uterus lifting sleeve comprises a uterus lifting cup and a connecting sleeve, the uterus lifting cup is mounted below the anti-falling device on the centralguide rod through mounting holes, the connecting sleeve is connected onto the central guide rod in a sleeving manner and located below the uterus lifting cup, and a sealing device can fill a gap between the connecting sleeve and the vaginal wall after air inflation; and a holding device is fixed with the lower end of the connecting sleeve, the central guide rod penetrates through the holding device to extend downwards, and a transmission device is arranged on the central guide rod at the extending part. The uterine manipulator has the characteristics of sufficiently exposing parametrium, preventing perforation and vaginal bruises and reducing spreading probability of tumors in the abdominopelvic cavity.

Description

technical field [0001] The invention relates to the technical field of lifting, in particular to a multifunctional palace lifting device. Background technique [0002] The information disclosed in the Background of the Invention is only intended to increase the understanding of the general background of the invention, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] In women, the vaginal vault is located in the space between the uterus and bladder, as well as between the uterus and rectum, and it is difficult for the surgeon to observe the exact position of the vaginal vault through laparoscopy; at the same time, it is necessary to swing the uterus during operations such as cutting the uterine ligament and free ureter , Adjusting the position of the uterus and other operations are assisted. Therefore, a uterine lifter with simple structu...

Problems solved by technology

In the case of uterine malignant tumor surgery, this operation may cause tumor cells to enter blood vessels due to extrusion of tumor tissue, increasing the chance of tumor spread

[0004] The inventor found in long-term work practice that: during the process of cutting the vaginal wall, the carbon dioxide gas in the abdominal cavity flows out through the incised vaginal wall, making it difficult to meet the space required for the operation in the abdominal cavity, interfering with the surgeon's surgical field of view, and seriously affecting the operation process

Some surgeons use methods such as packing gauze in the vagina to prevent gas leakage in the pelvic and abdominal cavity. The implementation is cumbersome and may cause abrasions to the patient's vaginal wall. The effect is only to slow down the rate of gas loss.

Some uterine lifters that use balloons or other similar objects as vaginal fillers are often designed to be fixed on the central rod of the uterine lifter. Vaginal sutures must be performed after the excised uterus is taken out through the vagina. Vaginal fillers such as balloons or other similar objects cannot Being reused, we can only rely on other methods to fill up the vagina, causing vaginal damage again, and the effect is not good

[0005] In addition, the present inventors found that: in malignant tumor surgery, the resected uterus is free in the pelvic cavity after cutting off the vaginal wall, often requiring the operator to take out the uterus through the vaginal stump to the pelvic and abdominal cavity. Tumor cells spread to the vaginal stump and even the pelvic cavity, increasing the risk of cancer recurrence

[0006] In a word, the inventors found that the traditional uterine lifter still has the disadvantages of complex design, time-consuming and labor-intensive use during operation, and poor sealing performance. If it is a malignant tumor operation, it is easy to cause tumor cells to spread and increase the risk of cancer recurrence. risk, low safety factor
