Description

This invention relates to a surgical instrument for laparoscopic surgery, and more particularly to a visualization medical system with a body cavity expansion device used in laparoscopic surgery. With advancements in endoscopic techniques, the number of examinations and surgeries that can be performed laparoscopically, including gastroscopy, colonoscopy, hysteroscopy, biopsy, and induced abortion, has increased significantly. Traditionally, various types of endoscopes, such as laparoscopes, thoracoscopes, and hysteroscopes, are inserted into the human body, and examinations and surgeries are performed under direct observation using lenses. To minimize surgical incisions, surgical incisions are usually kept as small as possible, and for this reason, the diameters of the related endoscopes and surgical instruments are also relatively small. However, because the tissues and organs within the human body are flexible, the body cavities of tissues and organs such as the uterus, stomach, and intestines are usually closed unless external force is applied. As a result, after inserting a small-diameter laparoscope into the body cavity, the tissue at the anterior end collapses. Therefore, especially in the case of the uterus and intestines, the observation area at the anterior end of the laparoscope becomes very small, often resulting in poor clinical observation. Therefore, to obtain better clinical observation results, it is necessary to further improve conventional laparoscopic medical equipment. Furthermore, in conventional techniques, the observation and treatment processes are often separated, requiring the exchange and manipulation of different instruments during clinical procedures, which is extremely inconvenient, especially in cases of biopsy or laser excision. Therefore, it is necessary to further improve and integrate the functions of conventional laparoscopic medical equipment. The visualization medical system with a body cavity expansion device of the present invention can expand the tip of the observation system by using the expansion end of the expansion mechanism provided at the tip of the observation system. This effectively expands the field of view, achieving excellent clinical observation results. The features of the visualization medical system with a body cavity expansion device of the present invention are as follows. The visualization medical system 100 with a body cavity expansion device comprises a body cavity expansion mechanism 1, an observation mechanism 2, a circuit system 3, a power supply system 104, an operating mechanism 5, and a display system 102. A. The body cavity expansion mechanism 1 is provided with an expansion end 11, which is located at the tip 5-1 of the operating mechanism 5, and can expand the body cavity at the front end of the observation mechanism 2, thereby expanding the observation field of view of the observation mechanism 2. B. The observation mechanism 2 comprises an illumination module 21, a lens module 22, a signal processing module 23, and a case 24. Images and videos observed by the lens module 22 within the light field of the illumination module 21 are processed by the signal processing module 23, and then output to the display system 102 by the circuit system 3 for display. The illumination module 21, the lens module 22, and the circuit system 3 are connected and then sealed and mounted inside the case 24. C, the observation mechanism 2 and the display system 102 are connected to the power supply system 104 via the circuit system 3. The visualization medical system with a body cavity expansion device of the present invention is provided with an expansion end 11 of the body cavity expansion mechanism 1 at the tip of the camera 22-1 of the observation mechanism 2. The expansion end 11 expands the body cavity at the front end of the observation mechanism 2, thereby enlarging the observation field of view of the observation mechanism 2. This system is particularly suitable for examinations and procedures such as hysteroscopy and colonoscopy. During use, the visualization medical system with the body cavity expansion device of the present invention is inserted into the body cavity, the expansion end 11 expands the body cavity, and the observation mechanism 2 observes the expanded area. The image and video signals observed by the lens module 22 are output to the display system 102 by the circuit system 3 and displayed. Because the body cavity at the front end of the observation mechanism 2 is expanded, the observation field of view of the lens module 22 becomes wider, resulting in a greater clinical observation effect. The observation mechanism 2 and the body cavity expansion mechanism 1 may be provided separately or integrated together. To reduce the cost of clinical use, the observation mechanism 2 and the body cavity expansion mechanism 1 may be provided separately. A sheath tube 12 is provided in the body cavity expansion mechanism 1, and the observation mech
