Noninvasive omnipotent uterine manipulator

Abstract

The invention provides a noninvasive omnipotent uterine manipulator, and belongs to the technical field of medical apparatuses, aiming at solving technical problems of the prior art which is not reasonable enough in design and the like. The uterine manipulator comprises a handle assembly and a uterine lifting assembly, wherein the handle assembly and the uterine lifting assembly are detachably connected and the uterine lifting assembly can work under the control of the handle assembly; the handle assembly comprises a handle and a strip-shaped bracket; the handle is hinged with the back end of the strip-shaped bracket; the uterine lifting assembly comprises a uterine lifting cup; a uterine swing rod is fixedly arranged in the uterine lifting cup and the front end of the uterine swing rod extends out of the uterine lifting cup; and a linkage mechanism, which can drive the uterine lifting cup to swing when the handle is rotated relative to the strip-shaped bracket, is arranged between the uterine lifting cup and the handle. The uterine manipulator provided by the invention has the advantages of being capable of preventing cross infection and convenient to use. A risk that the bottom of a uterus is pierced is avoided. The uterine manipulator, which adopts a locating bag for implementing locating, is more in line with tumor-free principle of a tumor surgery; in addition, by virtue of the locating bag, backflow of liquid is completely prevented; and pneumoperitoneum can be maintained when a vaginal wall is incised, so that an operative field is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a non-invasive all-round uterine lifter. Background technique [0002] With the popularization and application of laparoscopic technology in the field of gynecology, almost all gynecological laparotomy has been replaced by laparoscopic surgery. Moreover, laparoscopic surgery has the advantages of minimally invasiveness, clear vision, fast recovery, and less bleeding that cannot be surpassed by open surgery. The vast majority of gynecological laparoscopic operations are inseparable from an important surgical instrument-uterine lifter. The original design of the uterine lifter is to manipulate the uterus to generate appropriate tension, reveal the surgical space or facilitate access to some special parts of the pelvis. Its application provides an important guarantee for the exposure of the female pelvic surgery field of view. [0003] Most of the existing uterine lifters ...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned scheme solves the existing problems of the existing uterine lifter to a certain extent, but there are still some problems: it is prone to cross-infection, it is difficult to locate, and it causes extrusion of tumor tissue during cervical cancer surgery, causing tumor cells to squeeze into adjacent veins. The vascular system violates the tumor-free principle of surgical operations, and it is difficult to prevent the reflux of liquids such as melanin dye. During a total hysterectomy, once the vaginal wall is incised, CO in the abdominal cavity 2 Will quickly flow away through the vaginal incision, pneumoperitoneum collapse and other technical problems
