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 present invention relates to a curved structure and an endoscopic device, a gastric tube device, and a mechanical joint using the curved structure. The bending structure includes a bendable part (20). The bendable part (20) includes a bendable piece (21) and a hose (27) arranged side by side. The outside of the hose (27) is in contact with the bendable part (20). The hose is connected to the outside of the member (21), and the hose can expand and contract relative to the bendable member as the pressure of the fluid in the tube changes, thereby causing the bendable portion to bend. The curved structure also includes an operating portion for changing the pressure within the hose. In one embodiment, the flexible portion (20) has three hoses (27) arranged around the flexible piece (21). The bending structure of the present invention realizes bending through the cooperation of the hose and the bendable part, 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...
