Title:
DISPOSABLE SECTION OF ENDOSCOPE HANDLE AND ENDOSCOPE
Document Type and Number:
WIPO Patent Application WO/2024/027161
Kind Code:
A1
Abstract:
Provided are a disposable section of an endoscope handle and an endoscope. The disposable section of the endoscope handle comprises a housing (100), a transmission assembly (200), an input assembly (300), and an output assembly (400). The transmission assembly (200) comprises an input gear (210) and a transmission member which are coaxially linked. The input assembly (300) comprises two first push rods (310) symmetrically engaged on both sides of the input gear (210). The output assembly (400) comprises a traction rope (410). The traction rope (410) is connected to the transmission member and an active bending section of the endoscope. The input assembly (300) is connected to the output assembly (400) by means of the transmission assembly (200). The input assemblies (300) of a plurality of disposable sections can always match the same reusable section, while the output assemblies (400) of the plurality of disposable sections can be different, so that the maximum bending angles at which the active bending section of the endoscope formed by connection can be bent are different, thereby satisfying different usage scenarios. When the usage scenario changes, the disposable section that matches the usage scenario can be replaced, so that the reusable section has universality, effectively reducing the cost of use.
