Uterine manipulator capable of preventing uterine perforation

Technical Field

The utility model relates to the technical field of auxiliary medical equipment, concretely relates to prevent fenestrate uterus of uterus ware of lifting.

Background

In the prior gynecological laparoscopic surgery, the use frequency of the uterine manipulator is very high, and the uterine side and the uterine rectum pouch can be fully exposed by using the uterine manipulator, so that convenience is brought to the surgery. The most common complication when the uterine elevator is used is uterine perforation, pelvic organ injuries such as intestinal canal and bladder injuries can be further caused after the uterine perforation, and for a patient with endometrial malignant tumor, the uterine perforation can cause cancer cells to spread to an abdominal cavity, so that the disease stage is increased, and the prognosis is influenced; for a female who does not have birth, local endometrium injury, pelvic adhesion and the like are caused after uterine perforation, and the birth is influenced. Therefore, there is a need to improve the conventional uterine manipulator to a uterine manipulator capable of preventing perforation of uterus.

The reason why the uterine perforation is caused by the uterine manipulator is mainly that the head end of the uterine manipulator is generally thin, the uterine manipulator has the advantage of smoothly passing through the cervix, but the pressure is obviously increased when the uterus is forcibly lifted because the contact area of the head end and the uterine cavity is small, so the uterine perforation is caused. After understanding the reason, the principle of the uterine perforation prevention uterine manipulator is to increase the contact area of the head end of the uterine manipulator and the uterine cavity without increasing the difficulty of the uterine manipulator passing through the cervix.

SUMMERY OF THE UTILITY MODEL

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Example 1: the uterine manipulator for preventing uterine perforation as shown in fig. 1 comprises a uterine manipulator body 1, wherein a protective bag 2 capable of realizing contraction/expansion is arranged at the top end of the uterine manipulator body 1;

the uterine elevator body 1 comprises a forceps body 11 and a uterine elevator rod 12; the forceps body 11 comprises a fixed handle 111, a control handle 112, a first forceps rod 113, a second forceps rod 114 and a mounting seat 115; the fixed handle 111 is movably arranged on the mounting seat 115 through a first clamp rod 113, and the first clamp rod 113 is connected with the mounting seat 115 through a pin shaft; the control handle 112 is movably mounted on the mounting seat 115 through a second clamp rod 114, and the second clamp rod 114 is connected with the mounting seat 115 through a pin shaft; the fixed handle 111 is movably connected with the control handle 112 through a pin shaft; one end of the womb lifting rod 12 can be arranged on the mounting seat 115; the protective bags 2 are positioned at two sides of the other end of the uterus lifting rod 12;

wherein, a cavity is reserved in the womb lifting rod 12, one end of the cavity is communicated with the protective bag 2, and the other end of the cavity is arranged at the bottom end of the womb lifting rod 12; the first clamp bar 113 is provided with a mounting groove 1330;

the protection bags 2 adopt inflatable bags which are connected with external inflation equipment, and the number of the protection bags 2 is two; the inflatable bag is connected with external inflation equipment through an inflatable tube, one end of the inflatable tube is installed on a cavity channel at the bottom end of the uterine manipulator 12, the other end of the inflatable tube is connected with the external inflation equipment, an air injection valve is arranged at the joint of the inflatable tube and the external inflation equipment, and the inflatable tube is placed inside the placement groove 1330; wherein, the external inflating equipment adopts a syringe, and when in use, the syringe is used for pumping 2mL of air, and then the air is flushed into the inflating bag through the inflating tube.

When in use, before the uterus lifting rod 12 of the uterus lifter enters the uterine cavity, the protective bag 2 is in a contraction state, namely is not full, and at the moment, the uterus lifter does not influence the passing of the uterus lifter through the cervical canal; after the womb lifting rod 12 enters the womb cavity, the air injection valve is opened, 2mL of air is pumped by the injector and then is injected into the inflatable bag through the inflation tube, and the head end supporting point is widened after the protective bag 2 is filled, so that perforation can be effectively prevented; after the inflation is finished, closing the air injection valve and taking down the injector; after the use, the air injection valve is opened, the air in the protective bag 2 is exhausted by the air duct, and then the uterine lifting rod 12 of the uterine lifter is taken out through the cervical canal.
