Improved endometrial hemostasis device

Abstract

The utility model discloses an improved endometrial hemostasis device, and relates to the technical field of gynecological hemostasis devices. The improved endometrial hemostasis device comprises an elastic cover body, a handle, a controller, a computer, a cervix uteri supporting pipe, a top rod-shaped air bag, a waist rod-shaped air bag, an atomized liquid medicine spraying hole, a liquid medicine conveying hose, a liquid medicine conveying header pipe, a first connector, a liquid medicine conveying header pipe, a flow pump, an atomized liquid medicine supply device, a first gas conveying pipe, a gas pressure adjusting mechanism, a spherical flow guide cover, a micro digital camera, a first solenoid valve and a control panel. The invention provides an air bag structure adaptive to uterine cavity, so that targeted hemostasis can be realized, and the hemostasis efficiency and the hemostasis effect are effectively improved.

Description

technical field [0001] The invention relates to the technical field of gynecological hemostatic devices, in particular to an improved uterine inner wall hemostatic device. Background technique [0002] Some devices for gynecological uterine hemostasis are disclosed in the patent literature. Air bags are usually used. Anti-inflammatory and hemostatic drugs are coated on the surface of the air bags. However, in the state of uterine bleeding, it is difficult to control the amount of hemostatic drugs on the surface of the balloon. If the local drug dosage is insufficient or the drugs on the outer surface of the balloon cannot contact the uterine wall due to the special structure of the uterine inner wall, it is easy to cause hemostasis failure. In addition, after the balloon is inflated, it will press the inner wall of the uterus. If the pressure is too high, it will easily lead to increased bleeding, and due to the obstruction of the balloon itself, blood will easily accumulate...

AI Technical Summary

Problems solved by technology

[0004] However, it is well known that the inner cavity of the uterus is an inverted triangle, and the inflated shape of the conventional spherical balloon is quite different from the shape of the inner cavity of the uterus. Therefore, when the inner wall of the uterus is squeezed, different parts of the uterine wall will bear different pressures, such as , the pressure on some parts is too large, even exceeding the limit of the patient, and another part of the uterine wall has not fully contacted the air bag; big bleeding

[0005] In view of the above problems, the description of the patent document mentions that the shape of the airbag can also be made to fit the shape of the uterine cavity. For this statement, the applicant also consulted some other similar patent documents, and there are more or less similar expression, but they all have one thing in common: the structure of the airbag that fits the shape of the uterine cavity is not given, so people can only think of making a triangular-like airbag with the means of the existing technology

[0006] According to the principle of pressure, even if it is a triangular airbag, when it is inflated, due to the large upper and lower areas, the relative pressure is relatively large, which will cause the upper and lower sides to over-inflate and bulge, thus excessively squeezing the front and rear walls of the uterus, and at the same time The side wall is excessively torn, this method obviously does not solve the above technical problems

However, the important basis why the above-mentioned patent documents can play a hemostatic effect is that the shape of the air bag can be adapted to the uterine cavity, otherwise, on the one hand, there is a risk that the patient cannot bear it or the wound is torn; The defect of uneven liquid distribution

[0007] In addition, in the existing patent documents of this type, hemostasis in the form of a balloon is a hemostasis in a blind state, which cannot accurately determine the position of the bleeding wound in the uterine cavity, nor can it be targeted at the bleeding wound In addition, it is impossible to evaluate the effect of the hemostasis process, resulting in the waste of liquid medicine and low therapeutic effect.
