Embodiment Construction

[0033] The technical solutions and other beneficial effects of the present invention will be apparent through the detailed description of specific embodiments of the present invention below in conjunction with the accompanying drawings.

[0034] The curved structure provided by the first embodiment of the present invention is as figure 1 and figure 2 shown. The bendable part 20 of this bending structure comprises a bendable part 21 and a flexible pipe 27, the bendable part 21 is a strip shape, the flexible pipe 27 and the bendable part 21 are placed side by side, and the extending direction of the flexible part 27 is in line with the direction of the bendable part 21. The direction of extension is basically the same, and the outer side of the hose 27 is attached to and fixedly mounted on the outer side of the bendable member 21 . The bendable part 21 has the characteristics of being easy to bend and not easy to elongate. The bendable part 21 of this embodiment is made of ru...

Abstract

The invention relates to a bendable structure and an endoscopic device, a gastric tube and a mechanical joint using the bendable structure. The bendable structure comprises a bendable part (20); wherein the bendable part (20) comprises a bendable component (21) and a flexible tube (27) which are arranged juxtaposedly; the outer side of the flexible tube (27) is connected with the outer side of the bendable component (21); and the flexible tube (27) can extend and contract relative to the bendable component (21) along with the change of the pressure of fluid in the flexible tube (27) so as to lead to the bend of the bendable part (20). The bendable structure further comprises an operational part which is used for changing the pressure in the flexible tube (27). In one embodiment of the invention, the bendable part (20) comprises three flexible tubes (27) which are arrayed at the periphery of the bendable component (21). The bendable structure can be bent through the match of the flexible tube and the bendable component (21) and has a simple structure and low cost.

Description

technical field [0001] The present invention relates to a bending structure, and to an endoscopic device, a gastric tube device, a mechanical joint, etc. using the bending structure, and the mechanical joint includes various bendable mechanical structures such as a manipulator, a manipulator, and a manipulator foot. Background technique [0002] Bending structures are widely used in various fields, for example, industrial manipulators and medical endoscopes all involve bending structures. An existing bending structure includes a bendable central shaft, several laminations mounted to the central column, and several traction ropes passing through the several laminations. The central axis passes through the center of the laminations, and there is a certain distance between each lamination. A plurality of through holes are provided near the outer periphery of the laminations, and the plurality of traction ropes pass through the through holes and are fixed to a frontmost laminat...
