Abstract
Description
Technical Field
[0001] This application relates to the field of endoscope technology, and more specifically, to a rotatable insertion part and an endoscope. Background Technology
[0002] Endoscopes, as important medical devices, are widely used in minimally invasive surgery. They can enter the body through natural cavities or minimally invasive openings to assist doctors in observation, diagnosis, and treatment. Endoscopes typically consist of an operating section and a slender, flexible insertion section. The active bending segment of the insertion section can be controlled by the operating section to adjust its bending angle to accommodate the needs of different body cavities.
[0003] However, existing endoscopic insertion devices have certain limitations in adjusting the angle. Because the insertion devices are mostly designed to be flexible, the rotation adjustment process is relatively complex and the operation is not flexible enough. Especially when multi-angle observation is required, doctors often need to repeatedly adjust the position of the insertion device, which not only increases the difficulty of operation but may also affect the efficiency of the operation.
[0004] Therefore, an endoscope with an easily adjustable rotatable insertion part is provided. Utility Model Content
