[0027] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0028] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0029] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0030] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0031] like Figures 1 to 3 As shown, the snake head end segment provided by this utility model is provided with a traction rope fixing groove 11 and a traction rope through hole 12. The snake head end segment refers to the segment located at the foremost end of the endoscope in the snake bone structure or snake bone assembly. A traction rope is fixed on the snake head end segment. By pulling the snake head end segment with the traction rope, the bending deformation of the snake bone structure or snake bone assembly can be controlled, thereby achieving the effect of controlling the movement of the endoscope.

[0032] The traction rope fixing groove 11 can be used to fix the traction rope. The traction rope can be fixed in the traction rope fixing groove 11 by welding or gluing. In practice, the traction rope can fill the entire traction rope fixing groove 11 or only fill part of the traction rope fixing groove 11.

[0033] The traction rope fixing groove 11 can be a straight groove or a curved groove extending along the central axis of the snake head end segment, or it can be an annular groove extending circumferentially along the snake head end segment. Of course, the traction rope fixing groove 11 can be set at any position on the snake head end segment, and it can be irregular in shape.

[0034] The traction rope through-hole 12 is connected to the traction rope fixing groove 11, allowing the traction rope fixed in the traction rope fixing groove 11 to pass through the traction rope through-hole 12. The traction rope through-hole 12 is used to introduce the free end of the traction rope fixed in the traction rope fixing groove 11 into the inner cavity of the snake head end segment, or to introduce the free end of the traction rope into the inner cavity of a component adjacent to the snake head end segment. In specific implementations, the traction rope through-hole 12 can be located at the end of the traction rope fixing groove 11, or it can be located at any position on the bottom of the traction rope fixing groove 11.

[0035] By providing the traction rope through hole 12, the traction rope fixed in the traction rope fixing groove 11 can smoothly enter the interior of the snake bone structure or snake bone component, thereby avoiding extension on the surface of the snake bone structure or snake bone component.

[0036] Those skilled in the art will understand that the number of traction rope fixing slots 11 is not unique. For endoscopes with multi-degree-of-freedom control requirements, multiple traction rope fixing slots 11 can be provided to accommodate the need for fixing multiple traction ropes. The number of traction rope through holes 12 can be equal to the number of traction rope fixing slots 11, that is, the traction rope through holes 12 and traction rope fixing slots 11 are provided in a one-to-one correspondence. However, in one specific embodiment, two or more traction rope fixing slots 11 can be matched with one traction rope through hole 12. In another specific embodiment, one traction rope fixing slot 11 can also be matched with two or more traction rope through holes 12.

[0037] The snake head end segment of this application is provided with a traction rope fixing groove 11 for fixing the traction rope, and the traction rope is introduced into the traction rope through hole 12 through the traction rope fixing groove 11, which ensures the stability and safety of the connection between the traction rope and the snake head end segment, reduces the risk of the traction rope detaching from the snake head end segment, and thus effectively improves the safety of the snake bone structure.

[0038] In one embodiment of the snake head end segment of this utility model, the depth and width of the traction rope fixing groove 11 are both greater than or equal to the diameter of the traction rope. This allows the traction rope to be completely embedded within the snake head end segment, preventing it from protruding from the outer surface of the segment. This effectively reduces the installation space required when connecting or fitting the snake head structure or assembly with other components of the endoscope, and also effectively avoids the problem of stress accumulation in the traction rope.

[0039] In one embodiment of the snake head end segment of this utility model, the traction rope fixing groove 11 is provided along the axial extension direction of the snake head end segment. In this embodiment, the length of the traction rope fixing groove 11 can be equal to the axial length of the snake head end segment, or the length of the traction rope fixing groove 11 can be less than the axial length of the snake head end segment.

[0040] In one embodiment of the snake head end segment of this utility model, the traction rope fixing groove 11 is arranged along the circumferential direction of the snake head end segment, and the length of the traction rope fixing groove 11 is greater than or equal to 1 / 2 of the circumference of the snake head end segment. In this embodiment, when the length of the traction rope fixing groove 11 is equal to the circumference of the snake head end segment, the length of the traction rope fixed in the traction rope fixing groove 11 can be greater than the length of the traction rope fixing groove 11. That is, the traction rope can be arranged in a non-linear manner in the traction rope fixing groove 11, or the traction rope can be arranged in a reciprocating folding manner in the traction rope fixing groove 11.

[0041] Furthermore, the traction rope fixing groove 11 is connected to the two traction rope through holes 12, so that both ends of the traction rope enter the inner cavity of the snake head end segment from the two traction rope through holes 12 respectively. In this embodiment, the traction rope arranged in the traction rope fixing groove 11 is continuous without any breaks, thereby further improving the strength of the traction rope and helping to more effectively prevent the traction rope from falling off.

[0042] In practice, the traction rope through holes 12 can be arranged opposite each other so that the traction rope between the two traction rope through holes 12 can be more stably fixed in the traction rope fixing groove 11.

[0043] In one embodiment of the snake head end segment of this utility model, the snake head end segment includes a traction rope fixing groove segment 1 with a traction rope fixing groove 11 and a component segment 2. The component segment 2 is fixedly connected to the traction rope fixing groove segment 1. The component segment 2 can be threaded, welded, glued, or integrally formed with the traction rope fixing groove segment 11. This structure of the snake head end segment can be assembled in a more flexible manner. For example, the traction rope fixing groove segment 1 and the component segment 2 can be formed separately first, and then assembled together in a predetermined manner. In specific implementation, multiple traction rope fixing groove segments 1 and component segments 2 with different configurations and sizes can be manufactured to assemble snake head end segments with different configurations.

[0044] At least one end of the traction rope fixing groove section 1 is provided with a component section 2. The traction rope fixing groove section 1 may be located at the end of the snake head end segment, or the traction rope fixing groove section 1 may be located between the component sections 2.

[0045] This invention also provides a snake bone assembly, which includes the snake head end segment of this invention.

[0046] In one embodiment of the snake-bone assembly of this utility model, the snake-bone assembly further includes multiple snake-bone segments, which are sequentially rotatably connected to form a curved segment. The head end segment of the snake-bone assembly is rotatably connected to the front end of the curved segment. The above-mentioned rotatable connection can be implemented in a manner well known in the art, such as a pivot connection or a ball-and-socket connection.

[0047] Furthermore, a traction rope limiting component is also provided on the inner wall of the snake bone segment. The traction rope through-hole corresponds to the traction rope limiting component. The traction rope limiting component guides the traction rope to extend in a predetermined direction within the snake bone assembly. The traction rope limiting component can be, for example, a positioning ring or tube on the inner wall of the snake bone segment, and the traction rope can pass through the positioning ring. Setting the traction rope through-hole to correspond to the traction rope limiting component ensures that the traction rope through-hole and the traction rope limiting component face the same direction. This allows the tension to act in the same direction on the snake bone when the traction rope is pulled, which is beneficial for controlling the deformation of the snake bone in the predetermined direction. This effectively improves the flexibility and stability of the traction rope pulling the snake bone assembly.

[0048] This invention also provides a laryngoscope comprising the snake head end segment of this invention. Alternatively, the laryngoscope comprises the snake bone assembly of this invention.
