What Are The Equipment And Instruments Of Hysteroscopy?
Hysteroscopy is a new, minimally invasive gynecological diagnosis and treatment technology, a fiber light source endoscope used for intrauterine inspection and treatment, including hysteroscope, energy system, light source system, perfusion system and imaging system; It uses the front part of the mirror body to enter the uterine cavity and has a magnifying effect on the observed part. It is intuitive and accurate as the preferred inspection method for gynecological bleeding diseases and intrauterine lesions.
What are the equipment and instruments of hysteroscopy?
Hysteroscopy is divided into hysteroscopy equipment and hysteroscopy electrical resection equipment according to its use. Hysteroscopy equipment is mainly used for diagnosis. It consists of hysteroscope and instruments, lighting system (cold light source, light guide), camera and imaging system (camera, medical display, endoscopic imaging system), uterine dilation and perfusion system, etc. Composition; if the equipment has a power energy system, it has the functions of electric cutting and electrocoagulation. If equipped with laser equipment, hysteroscope can use laser to cut tissues in the uterine cavity.
Hysteroscopy is simple in instruments, and the terminal connectors of various equipment are mostly combined in one handle, and there is no need to disassemble. According to the condition of the hysteroscope body, it is divided into soft hysteroscope and rigid hysteroscope. Soft hysteroscopy is not easy to control. Because of its small outer diameter, there is no need to dilate the vagina or the uterus. It is often used for menopausal or adolescent women. Rigid hysteroscope is commonly used and can be used for conventional plasma disinfection. The outer diameter is 2.5~6.6mm, which can meet various clinical needs, and can be used for simple cutting, foreign body removal and other operations.
Hysteroscopy resectoscopes can be divided into monopolar resectoscopes and bipolar resectoscopes according to the different energy equipment. The difference between the two is that the current loop is different, and the mirror body, handle, inner sheath and outer sheath are all There is no obvious difference. Attention should be paid to the operation: the unipolar resectoscope uses glucose solution and other non-electrolyte solutions, and the electrodes should be attached before the operation, otherwise there will be no current loop, and the effects of resection and electrocoagulation cannot be produced; while the current loop of the bipolar resectoscope There is no need to stick electrode pads on both ends of the cutting electrode. Use a solution containing electrolytes such as 0.9% sodium chloride solution to expand the uterus.
The main purpose of hysteroscope:
Hysteroscope is an endoscope used for intrauterine examination and treatment. Under hysteroscopy, tubal intubation can be used for patency inspection. If the fallopian tube is found to be blocked or blocked, it can be treated with dredging at the same time, and the effect is good. In addition, hysteroscopy can directly and clearly observe the situation in the uterine cavity. Whether there are any intrauterine factors leading to infertility, and necessary surgical treatments for abnormal conditions can be performed at the same time. At present, hysteroscopy has become one of the common methods for the examination and treatment of female infertility.
Hysteroscopy can not only determine the location, size, appearance and scope of the lesion, but also make detailed observations of the tissue structure on the surface of the lesion, and obtain materials or locate and curettage under direct vision, which greatly improves the diagnosis of intrauterine diseases. Accuracy, update, development and make up for the shortcomings of traditional diagnosis and treatment methods.
For most patients who are suitable for diagnostic dilatation and curettage, it is more reasonable and effective to perform hysteroscopy to determine the location of the lesion before biopsy or dilatation and curettage. Hysteroscopic surgery can diagnose and treat a variety of diseases, such as women's dysfunctional uterine bleeding, submucosal fibroids, endometrial polyps, intrauterine contraceptive rings, and residual embryonic tissue after abortion. After hysteroscopic treatment, not only does patients who need to remove the uterus by traditional methods avoid laparotomy, but also preserves the uterus. For patients with bleeding disorders such as thrombocytopenia, hemophilia, and leukemia, the uterine cavity Endoscopic surgery is also safe.
In addition, hysteroscopy can also perform vaginal and uterine cavity examinations for young girls and unmarried women, and timely and accurately find abnormalities in the place and perform corresponding treatments. At the same time, it can also protect the integrity of the hymen and reduce the suffering of patients. Hysteroscopy can also be used to diagnose the cause of infertility, uterine deformity correction, and if necessary, it can also be used to diagnose early endometrial cancer.
