Title:
CONTROLLABLE CURVED TUBE STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2019/218947
Kind Code:
A1
Abstract:
A controllable curved tube structure: connecting structures are disposed on a tube wall in at least two directions in the circumferential direction of the controllable curved tube (100), and a curved structure is disposed on a tube wall that spaces connecting structures; the connecting structures comprise open slots (110) that are alternately arranged in the axial direction, any two adjacent open slots (110) sharing a side tube wall (101); the curved structure is at least provided with slits (120) that are arranged in the axial direction, the slits (120) extending along the circumferential direction of the tube wall, and the open slots (110) and the slits (120) communicating in one-to-one correspondence. Since one side tube wall is shared between any two adjacent axial open slots (110) in the circumferential direction of the connecting structures, the controllable curved tube is integrally connected together without a risk of partially falling off; meanwhile, the open slots (110) and the slits (120) communicate in one-to-one correspondence, which facilitates controlling the degree of the curve of a tubular body by means of controlling the degree of displacement, providing convenience for surgical operations.
