Problems solved by technology

[0003] In the diagnosis and treatment process of modern medicine, endoscopes with smaller diameters and bending radii are more and more required, that is, snakes with smaller diameters and bending radii are required. However, the existing two-way snakes generally have two traction rods inside the snake. The steel wire rope used and the traction channels for placing the wire rope in two rows can realize the bending of the snake bone in two directions by controlling the ends of the two steel wire ropes connected to the snake bone, but this will inevitably cause the inner space of the snake bone to be crowded and narrow, which is not conducive to snake The reduction of bone diameter is also not conducive to the arrangement of cables, light beams, water and gas pipes, and clamp pipes inside the snake bone.

Embodiment 1

[0027] Refer to attached figure 1 and attached figure 2 , a unilaterally driven two-way snake provided in Embodiment 1 of the present invention, including a snake body and a traction part, the snake body includes an elastic support 1 and a plurality of joints 2, and the elastic support 1 One side is bent to form an arc, and a plurality of joints 2 are sequentially arranged on the outer arc surface of the elastic support 1, and the traction part runs through the main body of the snake bone, and is used to pull the main body of the snake bone toward the elastic The bending movement is performed in the direction opposite to the bending direction of the support member 1 .

[0028] In some possible implementations, the elastic support 1 is made of elastic metal material such as stainless steel or titanium alloy metal material, the elastic metal material is first fixed into an arc bent to a certain side by a tool clip, and then After the heat treatment process, the elastic suppor...

Embodiment 2

[0034] Embodiment 2 of the present invention provides another two-way snake driven by one side, which includes a snake body and a traction part. The snake body includes an elastic support and a plurality of joints, and the elastic support is bent to one side to form arc-shaped, a plurality of joints are sequentially arranged on the outer arc surface of the elastic support, and the traction part runs through the main body of the snake bone, and is used to pull the main body of the snake bone toward the opposite direction of the bending direction of the elastic support direction for bending motion.

[0035] In some possible implementations, the elastic support is made of elastic metal material such as stainless steel or titanium alloy metal material, the elastic metal material is first fixed into an arc bent to a certain side by a tool clip, and then heat-treated After processing, the elastic support member is permanently bent into an arc shape and has a certain resilience.

Embodiment 3

[0040] Embodiment 3 of the present invention provides an endoscope. The endoscope includes a bending part and a control end. It is connected to the control end, and when the pulling wire is pulled and released by the control end, the bidirectional bending of the bending portion can be realized. For details, please refer to the description of the above-mentioned embodiments, and details will not be repeated here.

Abstract

The invention relates to a single-side-drive bidirectional snake bone which comprises a snake bone body and a traction part. The snake bone body comprises an elastic supporting piece and a plurality of bone joints. The elastic supporting piece is bent to one side to form an arc shape. The bone joints are sequentially arranged on the outer arc surface of the elastic supporting piece. The traction part penetrates through the snake bone body and is used for pulling the snake bone body to be bent in the direction opposite to the bending direction of the elastic supporting piece. The invention further relates to an endoscope. The endoscope comprises the bidirectional snake bone. By means of the bidirectional snake bone and the endoscope, the diameter of the bent part of the bidirectional snakebone and the endoscope can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of endoscopes, in particular to a bidirectional snake driven by one side. Background technique [0002] Endoscope is a medical device commonly used in modern medicine, which includes an insertion part for direct insertion into the human body, a curved part that can be bent at will, and a control end part for manual control of the operating handle, wherein a snake is arranged inside the curved part Bone, the bending of the snake bone can be realized by controlling the end part through manual operation, and then the bending of the bending part can be realized. [0003] In the diagnosis and treatment process of modern medicine, endoscopes with smaller diameters and bending radii are more and more required, that is, snakes with smaller diameters and bending radii are required. However, the existing two-way snakes generally have two traction rods inside the snake. The steel wire rope used and the traction channe...
