Embodiment 1

[0031] Such as figure 1 As shown, the present invention provides a curved structure for inserting a hose. The curved structure includes: a plurality of snake bone middle sections 300, a plurality of snake bone middle columns 200 (divided into snake bone middle column 1 is 200a, snake bone middle column 2 It is 200b), connecting rope 100.

[0032] The middle section of snake bone 300 has a first central hole, and four small holes 3001 for the connecting rope 100 to pass through are evenly arranged along the wall thickness direction;

[0033] The center of the snake bone middle column 200 has a second central hole 2001, and the inner diameter of the center hole matches the diameter of the small hole 3001 of the snake bone middle section;

[0034] The second central hole 2001 of the snake bone middle column 200 and the small hole 3001 of the snake bone middle section 300 are staggered in series through the connecting rope 100, and a layer of snake bone middle is placed between every tw...

Abstract

The invention provides a curved structure comprising a plurality of snake bone middle sections, snake bone middle columns and connecting ropes, wherein each snake bone middle column includes snake bone middle columns 1 and 2. A layer of snake bone middle columns is staggered in the symmetrical direction between the adjacent snake bone middle sections, the snake bone middle column 1 is arranged between the snake bone middle sections at one end of a snake bone, the snake bone middle columns 1 and 2 are alternately arranged in three directions between the snake bone middle sections at the other end, the snake bone middle column 1 is always used in the other direction, and the center of each snake bone middle section is provided with a first center hole. Four small holes for the connecting ropes to penetrate are evenly formed in the wall thickness direction. The center of each snake bone middle column is provided with a second center hole, the second center holes and the small holes of thesnake bone middle sections are in staggered series connection through the connecting ropes, and by control of the extension of the connecting ropes, the snake bone middle sections are driven to deviate with the snake bone middle columns as fulcrums. The invention also provides a corresponding insertion hose and other devices. By adoption of the technical scheme, the problems in the prior art thata curved structure is complex in structure and the bending angle cannot be accurately controlled are solved.

Description

Technical field [0001] The invention relates to the technical field of medical instrument endoscopes, in particular to a bending structure, an insertion hose and equipment thereof. Background technique [0002] Medical endoscopes and laparoscopic equipment usually include a flexible bending part, which changes the direction and angle of the probe by bending, which is convenient for expanding the field of view and adapting to the bending part of the cavity. The existing technical solution is derived from bionics, that is, simulating the bending principle of animal spine, and designing a bending structure called snake bone. The basic principles of most of the current bending schemes are based on this snake bone structure. The snake bone structure is connected by multiple structural units similar to the snake bone spine unit in a certain way. There is a gap between each structural unit. The structural unit is bent by filling the gap by tilting, and the bending of multiple structura...
