Title:
DEFLECTION JOINT STRUCTURE, STAPLER AND MEDICAL EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2023/124394
Kind Code:
A1
Abstract:
A deflection joint structure (100), a stapler, and medical equipment. The deflection joint structure (100) realizes the deflection of a deflection assembly (A) relative to a fixed assembly (B), and comprises a first connection part (101), a second connection part (102) and a joint part (103). The joint part (103) is partially arranged in the first connection part (101), and the other part is arranged in the second connection part (102), the joint part (103) comprising a plurality of rolling members (301). The rolling members (301) are distributed along a middle space (k1) of the joint part (103) to form a contact space (k2) for arranging an operation assembly (C). At least in the case of deflection, rolling friction is generated, in the contact space (k2), between at least one of the plurality of rolling members (301) and the operation assembly (C). Therefore, when the operation assembly (C) controls the deflection assembly (A) to deflect relative to the fixed assembly (B), the deflection joint structure (100) can, with lower energy loss, provide more effective support for the operation assembly (C), thereby preventing failures such as instability and buckling of the operation assembly (C).
