Amnion insertion device

Abstract

The invention provides an amnion insertion device, relates to a device for insertion outward expansion amnion in urgent cervical cerclage. More specifically, the invention aims to provide an amnion insertion device used in cervical cerclage in which an expansion balloon is inflated by fluid pressurized by an air injection tube integrally combined with the inside of an external pipe and a through hole so as to push the bulging amnion into the uterine lumen without damage and then to stitch the cervix to complete treatment of cervical incompetence, the expansion balloon provided at the front portion of the air injection tube is not deformed and is not pushed backward during the process of pushing the bulging amnion into the uterine lumen so as to easily perform cervical cerclage, and the external pipe and the air injection tube are integrally provided so that an operator may operate the amnion insertion device while grasping the amnion insertion device with one hand and perform cervical cerclage with the other hand, thus maximizing efficiency of cervical cerclage.

Description

technical field [0001] The present invention relates to an amniotic membrane insertion device, in more detail, to a device for inserting outwardly expanded amniotic membrane into the cervix during an emergency cervical cerclage operation, and in further detail, to a device for cervical cerclage Surgical amniotic membrane insertion device, which is composed of an air injection tube integrated into the external tube and a balloon inflated by air pressurized through the flow hole, so that the expanded amniotic membrane can be inserted into the uterine cavity without damage and then sutured to treat Cervical insufficiency, at this time, in the process of inserting the amniotic membrane, the inflation balloon formed at the front end of the air injection tube will not be deformed or pushed to the rear, therefore, cervical cerclage is easy to perform, and, by inserting the external The tube and the air injection tube are integrated, and the operator holds the amniotic membrane insert...

AI Technical Summary

Problems solved by technology

[0009] However, the Korean Patent No. 710905 has the following problems, that is, figure 2 As shown, since the inflation balloon 30 is attached to the outer diameter of the front end of the air injection tube 10, even if the rear part of the inflation balloon is fixed on the guide tube 40, in the process of inserting the expanded amniotic membrane, due to structural problems, the The inflation balloon 30 also moves to the left and right or is pushed back, so it becomes difficult to insert the inflated amniotic membrane into the uterine cavity

[0010] In particular, in the Korean Patent No. 710905, the air injection tube 10 for injecting air into the inflation air bag 30 and the guide tube 40 coupled to the outer peripheral surface of the air injection tube 10 are independent components and It is not an integral type, so there is a problem that during the cervical cerclage operation, a person holds the guide tube 40 of the amniotic membrane insertion device with one hand and the air injection tube 10 with the other hand. Next, the expanded amniotic membrane is inserted into the uterine cavity while operating. Therefore, when the amniotic membrane insertion device of the Korean Patent No. 710905 is used for cervical cerclage, the person who operates the amniotic membrane insertion device and the cervical cerclage operation are required. Therefore, not only is manpower wasted, but also, when two or more people perform the operation, unexpected results of the operation will occur due to mutual incoordination.

[0011] Moreover, in the Korean Patent No. 710905, since the thickness of the inflatable air bag 30 is very thin, and during the operation of inserting the inflated amniotic membrane into the uterine cavity, the inflatable air bag 30 will be pushed to the rear or toward the left and right As a result, the amniotic membrane protrudes a lot and the amniotic membrane will be damaged when it is barely inserted into the amniotic membrane. When treating patients with amniotic membrane damage, it is necessary to pump out the partial amniotic fluid in the amniotic membrane first to prevent damage to the amniotic membrane. After amniocentesis, the size of the amnion is reduced, and then the protruding amnion is inserted into the uterine cavity using an amnion insertion device.

[0012] In addition, with the existing amniotic membrane insertion device, when the amniotic membrane is inserted into the uterine cavity, the endometrium is uneven and elastic, and the inflation balloon is not easy to block the endometrium, and there is a problem that the amniotic membrane will protrude from the gap
