a hysteroscope

Abstract

The invention discloses a hysteroscope. The hysteroscope comprises a hysteroscope sheath and an endoscope which is arranged in the hysteroscope sheath, the hysteroscope sheath comprises an inner sheath body and an outer sheath body, the outer sheath body is provided with a water inlet and a water outlet, an operating electrode is arranged in the inner sheath body, a cleaning device is arranged on the side portion of the endoscope, and the cleaning device is driven by a driving device arranged outside the hysteroscope sheath to scrub the surface of the endoscope; a sliding block is movably arranged on the outer sheath body, a suction tube is arranged between the inner sheath body and the outer sheath body, and the sliding block is connected with the suction tube. The cleaning device is arranged on the hysteroscope sheath to clean the surface of the endoscope, the situation that tissue scraps block the view of the endoscope is avoided, and it is guaranteed that an operation is conducted smoothly. Due to the fact that the suction device is arranged, the detached tissue scraps can be sucked out of the uterine cavity, and the situation that the operation sight line is blocked due to the fact that a large amount of tissue floats in the uterine cavity is avoided. A tissue collection tank is designed to be a two-layer solid-liquid separator device, the blood or other biological interstitial fluid and biological tissue are separated, and collection of biological tissue samples is facilitated.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a hysteroscope. Background technique [0002] Hysteroscope is clinically used to treat uterine cavity lesions. It is a common equipment for gynecological minimally invasive operations. There will often be some intracavitary tissue shedding or bleeding, because the volume of the uterine cavity is small, these will blur the lens of the hysteroscope, thus affecting the doctor's visual observation; and once the detached tissue is large, it cannot continue To perform a surgical operation, the hysteroscope must be taken out, the tissue removed, and then the second operation is performed; once such surgical work is repeated many times, the operation time is prolonged, which not only brings certain psychological pressure to the medical staff and patients, but also Because it increases the number of times the hysteroscope enters and exits the cervical canal during the operation, the ri...
