Disposable curved hysteroscope protective cannula and hysteroscope

Abstract

This invention discloses a disposable curved hysteroscopy protective sheath and a hysteroscopy, comprising a hysteroscopy body and a disposable protective sheath body. A handle groove is fixedly installed through the lower end of the hysteroscopy body. A pressing spring is fixedly installed inside the handle groove, and a pressing handle is fixedly installed at the front top of the pressing spring. A sliding inner ring is fixedly installed at the top of the pressing handle, and a limiting protrusion is formed on the outer curved surface of the sliding inner ring. A limiting groove is formed through the middle inner wall of the hysteroscopy body, and a sliding outer ring is fixedly installed at the outer top of the limiting protrusion. A receiving circular groove is formed on the inner wall of the front end of the sliding outer ring, and a return spring is fixedly installed at the top of the receiving circular groove. This invention enables imaging examination of the female reproductive system while protecting the hysteroscopy body through the disposable protective sheath body, thus avoiding direct contact between the hysteroscopy body and the human body.
