Description

A new auxiliary system for gynecological surgery

technical field

The invention belongs to the field of medical devices, and in particular relates to a medical device for obstetrics and gynecology operations, which is suitable for visualized abortion operations and other intrauterine operations.

Background technique

Uterine distension technology is widely used in gynecological operations and intrauterine examinations, and its fundamental function is to expand the closed uterine cavity to form a visual environment and an operating environment. However, in many current gynecological operations, such as artificial abortion, due to the lack of suitable uterine distension methods, it is very difficult for doctors to perform visual operations, which also increases the possibility of complications to a certain extent.

When a suitable cavity environment can be obtained, how to "see" the target area is very important. There are mainly direct visualization and indirect visualization currently used clinically. Direct visualization refers to transmitting real-time and real images of the target to the operator, such as cameras, optical fibers, rigid endoscopes, chromoendoscopes, capsule endoscopes, etc. The fundamental method is to obtain images through sensors. The difference is that the positions of sensors and light sources are different. Indirect visualization is relative to direct visualization, such as: ultrasound visualization, B-ultrasound visualization, CT, nuclear magnetic resonance, etc. Generally, the images obtained are not intuitive tissue images.

The current visualization methods are mainly: ultrasound visualization, or B-ultrasound visualization. The disadvantage of this method is that it is difficult to distinguish whether the embryo sac has been completely sucked. At the same time, many instruments are used and the steps are cumbersome. Many doctors are not willing to spend a lot of effort to achieve an indirect visible effect. Therefore, in a large number of hospitals, this visualization method is resisted by some doctors.
