BENDABLE GUIDE SHEATH TUBE AND GUIDE DEVICE

WIPO Patent Application WO/2024/007568

A1

The present application provides a bendable guide sheath tube and a guide device. An intermediate tube section of the bendable guide sheath tube is connected between a bendable tube section and a sheath tube joint. The bendable tube section comprises at least two mortise and tenon connectors, and the mortise and tenon connectors are sequentially inserted in an axial direction of the intermediate tube section. The bendable tube section is used for bending relative to the axial direction of the intermediate tube section by means of relative sliding between the mortise and tenon connectors when subjected to a lateral force. In the present application, the bendable tube section is configured to be at least two mortise and tenon connectors inserted in the axial direction of the intermediate tube section, so that the bendable guide sheath tube can be close to stone fragments in the kidney, and then the stone fragments are flushed out by means of the water flow infused in the operation, thus improving the discharging efficiency of the stone fragments, avoiding the situation that stone powder affects the visual field or is accumulated in the kidney to affect the operation efficiency, and improving the stone removal rate.
