Abstract

The invention relates to a transurethral intravesical operation instrument system for non-muscle invasive bladder cancer. The system comprises an endoscope with multiple passages, a) a tail end-bendable operation instrument with a bendable joint and / or b) a tail end-bendable operation instrument with a pre-bent pipe structure. According to the system, the tail end-bendable operation instrument with the bendable joint and the tail end-bendable operation instrument with the pre-bent pipe structure are independently matched with the endoscope with the multiple passages for use or the two operation instruments are simultaneously matched with the endoscope with the multiple passages for use, so that operation instrument tail ends in various shapes can be obtained, an encircling operating angle is formed, fine operation is facilitated, and an operated part can be observed in real time; compared with the prior art, the system has the characteristics of fine operation, all-angle operation, no blind zones, complete excision, convenience in the mastering of the excision depth, humanized operation and the like, the cure rate of non-muscle invasive bladder cancer is expected to be increased, operation complications are reduced, and the cancer recurrence rate is lowered.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an intracavity surgical instrument system for non-muscle-invasive bladder tumors through the urethra. Background technique [0002] At present, endovascular surgery is an important method for the treatment of non-muscle invasive bladder tumors and other diseases. With the continuous development of science and technology, endovascular surgery treatment methods are emerging in an endless stream, including monopolar resection, plasma resection, holmium laser, thulium laser Surgery, fluorescein or NBI-assisted resection, etc. [0003] Overall, transurethral resection of bladder tumor (TURBt) is still the main method for the treatment of non-muscle-invasive bladder cancer, but it still has certain limitations. Especially for bladder tumors with large tumor volumes that cannot be completely removed in a single operation, or due to irregular tumor shapes, multiple tumors, a...
