Title:
BENDING SECTION STRUCTURE, PROBE INSERTION STRUCTURE, AND FLEXIBLE PROBE
Document Type and Number:
WIPO Patent Application WO/2023/116666
Kind Code:
A1
Abstract:
A bending section structure, a probe insertion structure, and a flexible probe. The flexible probe comprises a handle, a probe insertion structure, and a camera module, which are connected in sequence. The probe insertion structure comprises a main tube body and a bending section structure connected to each other. The bending section structure is composed of a plurality of bending sections (1) connected in sequence, wherein the adjacent bending sections (1) can rotate relatively; one end of each bending section (1) is provided with a rotating central portion (11), two sides of the rotating central portion (11) are each provided with a slot (12), and the rotating central portion (11) is provided with a first main limiting structure (111); and the other end of each bending section (1) is provided with a plurality of accommodating spaces (14), each accommodating space (14) is formed by a plurality of hooks (13) that can axially limit the adjacent bending sections (1), and a second main limiting structure (141) is provided in the accommodating space (14). The bending section structure has a good limiting effect and a high lateral bending resistance, thereby ensuring the reliability and safety of the bending section structure during bending.
