Description

Angle-adjustable hysteroscope and method of use thereof

technical field

The invention belongs to the technical field of medical endoscopes, in particular to a type of endoscope used for uterine cavity inspection, and in particular to an angle-adjustable hysteroscope.

Background technique

The hysteroscopic system can help doctors check the situation of the uterine cavity under direct vision, and can also treat some uterine cavity diseases by adding some surgical instruments to the hysteroscopic system with the assistance of the hysteroscope. The application greatly improves the accuracy of diagnosis of gynecological diseases and the safety of treatment. Therefore, the hysteroscopic system is widely used in infertility, uterine submucosal fibroids, endometrial polyps, postmenopausal vaginal bleeding, intrauterine adhesions, ring incarceration and other gynecological diseases that design the uterus.

In the clinical hysteroscopy system, a rigid hysteroscope is mostly used, and the main components are a mirror sheath and a speculum. According to the different anterior oblique angles at the top of the lens body, it can be divided into different slopes such as 0 degree, 12 degrees, 20 degrees, 30 degrees and 45 degrees, and 30 degrees are commonly used clinically. When there is a blind spot in the inspection, it is necessary to replace the speculum with different angles. It is easy to cause damage to the patient's uterus when the speculum is replaced repeatedly, and the cost will be greatly increased.

Patients with a special uterine position are prone to extreme forward or backward flexion; some lesions are in a special position, such as the uterine horn near the opening of the fallopian tube, or the original cesarean section scar (the place is weak and often bulges outside the uterus and protrudes toward the bladder) ). Often due to the existence of hysteroscopic blind spots, it is difficult to observe or touch the lesion, missed diagnosis, misdiagnosis, and even surgical complications such as uterine perforation may occur. If the existing rigidity is changed, and the hysteroscope with an invariable angle is changed into a hysteroscope with an adjustable angle, then the problem will be solved.

A hysteroscope is a type of endoscope. Although there are various angle-adjustable endoscopes in the prior art, since the main detection part of the hysteroscope is the uterus, it has its particularity, and the angle-adjustable endoscopes applied to other parts cannot be directly applied to the uterus. Therefore need a kind of endoscope specially for the adjustable angle of hysteroscope.

The present invention aims at the problem that existing hysteroscopes have blind spots, which are easy to miss, and need to be replaced repeatedly with different angles for comprehensive detection, and provide a kind of endoscope with reasonable structure, easy to use, which can be inserted into the uterine cavity at one time, and can be adjusted through angle adjustment.
