Problems solved by technology

[0002] Vaginal dilators are often used during gynecological examinations, but most of today’s vaginal dilators are composed of two expansion plates and a handle, and such dilators are not stable after dilating during use, which often causes damage to the vagina. Mirrors or surgical instruments are obstructed, and the old-fashioned vaginal dilators need to be manually squeezed and then manually locked when they are opened, which makes it extremely inconvenient to use. Therefore, we propose a dilator for gynecological diseases. device

Abstract

The invention discloses an expander for examining gynecological diseases. The expander comprises a shell, the shell is composed of an upper half shell and a lower half shell which fit each other, anda circular cavity is formed in the middle of the fitting portion of the upper half shell and the lower half shell; a spreading device used for spreading the upper half shell and the lower half shell is inserted into the circular cavity, top heads are integrally formed in the right ends of the upper half shell and the lower half shell, and the front and rear ends of the bottom face of the upper half shell are rotatably connected with the ends of hinge plates; the other end of each hinge plate is rotatably connected with the upper surface of the lower half shell, limit clamping grooves are formed in the rotation junction between the upper half shell and one hinge plate and the rotation junction between the lower half shell and the other hinge plate, and top plates are fixedly connected to the right ends of the upper half shell and the lower half shell. Through the application of the upper half shell, the lower half shell, the limit clamping grooves and the hinge plates, the expander hasthe advantage of stable spreading, and meanwhile the functions of convenient spreading and automatic locking are achieved through application of the spreading device and the hinge plates.
