Description

Novel hysteroscopy scope and application thereof

Technical Field

The invention relates to the technical field of medical instruments, in particular to a novel hysteroscopy scope and application thereof.

Background

The hysteroscope is a new and minimally invasive gynecological diagnosis and treatment technology, is a fiber light source endoscope used for examination and treatment in the uterine cavity, and comprises the hysteroscope, an energy system, a light source system, a perfusion system and an imaging system; the front part of the endoscope body enters the uterine cavity, and the endoscope body has an amplification effect on the observed part, so that the endoscope body is visually and accurately a preferred examination method for gynecological hemorrhagic diseases and intrauterine lesions.

Compared with the traditional gynecological examination, the hysteroscopy can not only discover the abnormality of the cervical canal of the uterine cavity and determine the position, size, range and texture of a focus, but also perform positioning material taking biopsy under direct vision, take out intrauterine foreign matters, separation membrane adhesion, sterilization and other simple treatment operations, thereby being an advanced minimally invasive diagnosis and treatment technology.

The hysteroscope can directly inspect intrauterine lesions, and can quickly and accurately diagnose most intrauterine diseases. It is estimated that hysteroscopy of indicated patients can increase the intrauterine abnormality rate detected by other traditional methods from 28.9% to 70%, wherein many patients have abnormality found by hysteroscopy and cannot be diagnosed by other traditional methods.

The hysteroscope on the market at present has two kinds of straight mirror and curved mirror, and the camera lens of straight mirror is the inclined plane of 30 degrees, and the camera lens of curved mirror is the disc, when carrying out the inspection of uterine cavity, if the patient's inner membrane is thicker, or the cervical canal is tighter, these two kinds of hysteroscopes get into the uterine cavity and rub the lower uterine segment inner membrane very easily, influence the operation field of vision, increase operating time and patient's misery. Meanwhile, clinically, patients with loose cervical ducts are common, water leakage in uterine cavities is serious, and the cervix is clamped by cervical clamps in order to prevent water leakage, but the pain of the patients is increased, vagus nerve excitation is increased, the blood pressure and the heart rate are reduced, and the risk of the patients is increased.

CN112826432A discloses a hysteroscope and sheath body structure, set up arc transition structure between the distal end through the sheath and the inner sheath and pass through, though can make the distal end of sheath body structure have convex transition structure, can avoid to a certain extent causing the damage to the uterine cavity at the in-process that stretches into the uterine cavity, however, the inner sheath face after the improvement completion still occupies certain volume in the space, when carrying out the inspection of uterine cavity, if the patient's inner membrane is thicker, or the cervical canal is tighter, the lower uterine segment inner membrane is still rubbed off more easily when the hysteroscope after the improvement gets into the uterine cavity, influence the operation field of vision, increase operating time and patient's misery.
