The hysteroscope [https://eleps.ru/katalog/gisterorezektoskopiya-i-ginekologiya-optika-gisteroskopy/] is intended for visual diagnosis of intrauterine pathology (cervical canal, isthmic region, uterine cavity), diagnostic hysteroscopy (assessment of the endometrium, determination of the location and size of the myomatous node and pallipoendometrium, detection of cervical pathology), as well as surgical procedures (taking biopsies, removing foreign bodies, removing polyps and submucous myomatous nodes) under visual control. The hysteroscope has a wide range of diagnostic and therapeutic capabilities. - Highly informative. The optical system of the hysteroscope, connected to the illuminator via a fiber optic light guide, provides good illumination with "cold light", which allows the doctor to see a real picture of the cavity being examined. - The 5 mm diameter diagnostic shaft of the hysteroscope allows, in an outpatient setting, without dilating the uterine cavity, to conduct diagnostic tests if endometrial pathology is suspected, to diagnose the causes of menstrual irregularities and infertility, and to identify pathologies of uterine development. - The surgical shaft of the hysteroscope ensures surgical interventions with the use of a semi-rigid endoscopic instrument using a liquid or gas medium to dilate the uterine cavity. - The use of the surgical shaft with biopsy forceps allows for a targeted biopsy and obtaining a sufficient volume of biopsy material. - The combination of an assessment of the hysteroscopic picture and biopsy data is the most accurate diagnostic method. - Using scissors, it is possible to perform targeted removal of endometrial polyps and dissection of intrauterine septa, and using forceps for removing foreign bodies, to capture and remove foreign bodies. - The design of the hysteroscope allows for examinations using video equipment from leading manufacturers. In general, different types of hysteroscopes differ in diameter, entrance angle of the visual field, direction of the visual field, and working length. - The diameter of the hysteroscope can be 4 mm. - The entrance angle of view is the angle within which the hysteroscope transmits the input image. - The direction of the visual axis is 0 °, 12 °, 30 °, 70 °. A distinction is made between diagnostic and surgical hysteroscopes. They differ in the design of the body, as well as the presence or absence of instrument channels with instruments. With the help of these devices it is possible to perform diagnostic hysteroscopy or simple manipulations: taking a biopsy, dissecting adhesions, removing small polyps, foreign bodies, etc. Surgical hysteroscope with an instrument channel. Purpose: operative hysteroscopy for intrauterine pathologies. Features: - the deflected ocular part of the endoscope allows you to free up the area for instrument manipulation; - the use of a 4 mm instrument expands the possibilities of surgical intervention; - a constant flow of fluid improves visualization of the endometrium and the walls of the uterine cavity; - an automatic valve prevents fluid leakage from the operated area and ensures comfort for the surgeon. A hysteroresectoscope is an instrument for extended electrosurgical operations in the uterine cavity: endometrial ablation, polyp removal, myomectomy for submucosal nodes, and adhesion dissection. A hysteroresectoscope consists of the following parts: - Optical tube; - Resectoscope tube (external and internal); - Obturator (for primary insertion of the device into the uterine cavity); - Working element, active or passive; - A set of instruments: loop electrode, ball electrode, cylinder electrode. Adjacent electrodes are connected to the working element. The larger the diameter of the loop, the safer and more effective it is. Small loops increase the duration of the operation and increase the risk of uterine perforation. Cutting loops angled away from the surgeon are used for endometrial resection in the uterine angulations and fundus, while loops angled toward the surgeon are used for endometrial resection of the uterine walls. Larger spherical and cylindrical electrodes are preferred for rapid completion of the procedure, but they impede visibility. Therefore, for normal-sized uteri, smaller electrodes are preferred. The working element of the hysteroresectoscope is activated by pressing the trigger. There are two types of operating mechanisms: active and passive. With an active mechanism, the electrode is initially extended from the housing and is inserted into it by pressing the trigger. With a passive mechanism, the electrode is initially positioned within the housing and is extended when the trigger is pressed. The electrode automatically returns to the housing after the trigger is released, performing tissue cutting and coagulation. The passive mechanism is safer to use, but the choice ultimately depends on the surgeon's preference.
