Abstract

The invention relates to the technical field of mechanical joints, in particular to a joint structure, a flexible joint and minimally invasive surgical forceps. The joint structure of the present invention is suitable for a plurality of series connection to form a flexible joint, including a rotating part, and a limiting part is provided on the circumference of the rotating part; one side of the base is fixedly connected with the rotating part, and the other side is provided with a The accommodating cavity for the rotation of the rotating part of the adjacent joint structure; the limiting part cooperates with the limiting part of the rotating part of the adjacent joint structure, and is arranged on the base so as to limit the circumferential rotation of the rotating part of the adjacent joint structure. The joint structure, flexible joint and minimally invasive surgical forceps of the present invention have high transmission efficiency and high control precision.

Description

Joint structure, flexible joint and minimally invasive surgical forceps technical field [0001] The present invention relates to the technical field of mechanical joints, in particular to joint structures, flexible joints and minimally invasive surgical forceps. Background technique [0002] Joints are structures necessary for the transmission of shear, compressive, and torsional forces, as well as for a variety of motions. It realizes rotation with multiple degrees of freedom, and the action is relatively flexible, suitable for working in narrow spaces, so it is widely used in the field of machinery middle. At present, in the prior art, such as U.S. Patent Document US20170095922A1, discloses a Articulation joints, which consist of alternating connections of connecting rods and universal joints that provide two orthogonal axes in the same plane The rotation of the articulated joint is achieved with a cable running through one or more joints, when the cable is selectiv...
