Problems solved by technology

[0002] Publication No. CN2822539Y discloses a swirl ring for a swirling artificial abortion device. We found in application that the width of the elliptical ring structure of this swirl ring cannot be adjusted during the process of wrapping pregnancy tissue, although The elliptical ring deviates to one side, but due to the different structure of the inner wall of the individual uterus, sometimes the elliptical ring is still far away from the pregnancy tissue, so it is not easy to perform the wrapping operation

Abstract

The invention relates to a swirl ring for a rotary artificial abortion device. The swirl ring comprises a fixed pipe; the fixed pipe is of a tubular structure; a metal rod capable of passing through the fixed pipe is arranged in the fixed pipe; and the front end of the metal rod is provided with a fixed ring which is made of memory alloy and can be contracted in the fixed pipe. According to the invention, through combination of the rod, the fixed ring and a steel wire, when an operator pushes the fixed ring to near pregnant tissues through the fixed pipe, a user can adjust the width of the fixed ring in a mode of pulling the steel wire, so that the outer diameter of an arc formed by an outer edge in a process that the fixed ring rotates along a central axis of the fixing pipe is enlarged,and thus the fixing ring can be closer to the pregnant tissues. Therefore, the fixed ring can more conveniently to reach the pregnant tissues, and the pregnant tissues are wound and taken by rotationof the fixed ring along the central axis of the fixed pipe.

Description

technical field [0001] The invention relates to a swirl ring, more precisely a swirl ring for a swirling artificial abortion device. Background technique [0002] Publication No. CN2822539Y discloses a swirl ring for a swirling artificial abortion device. We found in application that the width of the elliptical ring structure of this swirl ring cannot be adjusted during the process of wrapping pregnancy tissue, although The elliptical ring deviates to one side, but due to the different structures of the inner wall of the individual uterus, sometimes the elliptical ring is still far away from the pregnancy tissue, so it is not easy to perform the wrapping operation. Contents of the invention [0003] The object of the present invention is to provide a swirl ring for a swirling artificial abortion device, which can combine a rod, a fixed ring and a steel wire. When the operator pushes the fixed ring to the vicinity of the pregnancy tissue through the fixed tube, the user Th...
