[0038] The technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this specification.

[0039] It should be noted that the terms "first," "second," etc., used in this specification, claims, and the foregoing drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, apparatus, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0040] like Figures 1 to 6 As shown in the figure, this specification provides a traction rope installation assembly, including a crimped steel pipe 10, a traction steel wire rope 20, and a first section of snake bone 30;

[0041] The crimped steel pipe 10 is crimped and connected to the traction steel wire rope 20 to form a whole (e.g., Figure 6 As shown in the figure), specifically, crimping pliers can be used to crimp the crimping steel pipe 10 and the traction steel wire rope 20 together; at the same time, the crimping force and other parameters of the crimping pliers can be controlled to ensure that the parameters are the same for each crimping, thus guaranteeing the crimping quality.

[0042] The first section of the snake bone 30 includes a first end 31, a second end 32, and a snake bone body 33. The first end 31 is used to connect to the endoscope module, and the second end 32 is used to connect to the snake bone segment. The snake bone body 33 is provided with a crimping groove 34. The crimping groove 34 is used to pass through and clamp the integral composed of the crimping steel pipe 10 and the traction steel wire rope 20. By clamping the integral composed of the crimping steel pipe 10 and the traction steel wire rope 20 with the crimping groove 34, the stability of the connection between the integral and the first section of the snake bone 30 can be ensured, so that the snake bone can be bent by pulling the traction steel wire rope.

[0043] The traction rope installation assembly provided in this specification is simple to operate and requires minimal technical skill from the operator. After simple training, the operator can operate it smoothly. Furthermore, the crimping parameters of the crimping pliers can be preset and fixed, ensuring that the crimping force between the traction wire rope and the crimping steel pipe is the same, thus guaranteeing the crimping quality. In addition, the tools required for operation are simple, and no large or complex equipment is needed. Only a manual crimping pliers are required to meet the usage requirements, and the operating environment will not cause harm to the operator's body.

[0044] It should be noted that when actually installing the traction rope installation assembly provided in the embodiments of this manual, the traction wire rope 20 should first be passed through the crimping groove 34 on the first section of the snake bone 30; then, the crimping steel pipe 10 should be fitted onto the end of the traction wire rope 20 that is passing through the crimping groove 34, so that the ends of the traction wire rope 20 and the crimping steel pipe 10 are flush, and the crimping steel pipe 10 and the end of the traction wire rope 20 should be crimped together using crimping pliers; finally, the end of the crimping steel pipe 10 that is crimped together with the traction wire rope 20 should be placed back into the crimping groove 34, and the other end of the wire rope 20 can be pulled to bend the snake bone by the crimping groove 34 holding the crimping steel pipe 10.

[0045] like Figure 1 As shown, the snake bone body 33 has a cutting slit, which is perpendicular to the axial direction of the snake bone body 33; the pressing groove 34 is located between two opposite cutting slits and is recessed into the snake bone body 33.

[0046] In this embodiment of the specification, the crimping groove 34 is made by stamping from the material of the snake bone body 33 itself, which helps to reduce manufacturing costs. The cutting slit is perpendicular to the axial direction of the snake bone body 33, and the subsequent traction steel wire rope 20 will pass through the formed crimping groove 34 along the axial direction of the snake bone body 33. Furthermore, the crimping groove 34 is recessed into the interior of the snake bone body 33, which helps to reduce the outer circumferential dimensions of the entire first segment of the snake bone 30.

[0047] In other feasible embodiments, the crimping groove 34 may also protrude outwards from the snake-bone body 33 to facilitate the passage of the traction wire rope 20. The specific method used can be determined according to the specific circumstances. For ease of explanation, the following description will use the example of the crimping groove 34 being recessed into the snake-bone body 33.

[0048] like Figure 5 As shown in the embodiment of this specification, a groove 341 is provided in the middle of the crimping groove 34, and the curvature of the groove 341 is adapted to the curvature of the outer diameter of the crimping steel pipe 10. This is to ensure that the groove 341 can fit tightly against the crimping steel pipe 10 when it is subsequently clamped and fixed, thus ensuring the stability of the clamping.

[0049] Furthermore, the distance between the two oppositely positioned cutting seams is adapted to the length of the crimped steel pipe 10.

[0050] Furthermore, the depth of the crimping groove 34 relative to the snake bone body 33 is adapted to the diameter of the crimped steel pipe 10.

[0051] Thus, the crimped steel pipe 10 can be completely engaged with the crimping groove 34. This ensures the clamping force of the crimping groove 34 on the crimped steel pipe 10, guaranteeing the stability of the traction wire rope 20 connection.

[0052] In some preferred embodiments, after the crimped steel pipe 10 is snapped into the crimping groove 34, adhesive can be applied between the crimping groove 34 and the crimped steel pipe 10 to further improve the stability of the connection.

[0053] In some preferred embodiments, the traction rope mounting assembly may further include a snake-bone outer skin;

[0054] The snake-bone outer skin is disposed on the outside of the first snake bone 30. The snake-bone outer skin is used to wrap the first snake bone 30 and the whole formed by the crimped steel pipe 10 and the traction steel wire rope 20. The snake-bone outer skin can prevent the whole formed by the crimped steel pipe 10 and the traction steel wire rope 20 from coming out of the crimping groove 34 of the first snake bone 30, further ensuring the stability of the installation between the traction rope, the crimped steel pipe and the first snake bone.

[0055] Furthermore, in this embodiment, the projected length of the cutting seam on the snake-bone body 33 along the direction perpendicular to the axis of the snake-bone body 33 can be greater than the projected length of the crimping groove 34 on the snake-bone body 33 along the direction perpendicular to the axis of the snake-bone body 33. That is, in this embodiment, the cutting seam has a reserved space for preparing for stamping. It is understood that the snake-bone body 33 will be involved in the process of forming the crimping groove 34; the aforementioned reserved space can prevent the snake-bone body 33 from deforming due to being involved, ultimately ensuring that deformation only occurs in the area between the two cutting seams. This embodiment does not limit the specific length of the cutting seam on the snake-bone body 33 along the direction perpendicular to the axis of the snake-bone body 33; the specific length can be set according to the actual situation.

[0056] In a more specific embodiment, the two ends of the projection of the cutting slit onto the snake-bone body 33 in a direction perpendicular to the axis of the snake-bone body 33 respectively extend to the two ends of the projection of the crimping groove 34 onto the snake-bone body 33 in a direction perpendicular to the axis of the snake-bone body 33. That is, in this embodiment, both the left and right sides of the cutting slit can have reserved space, which can further prevent the snake-bone body 33 from deforming during the stamping process of the crimping groove 33.

[0057] like Figure 2 and Figure 3 As shown in the embodiments of this specification, there are two crimped steel pipes 10, two traction steel wire ropes 20, and two crimped grooves 34. The two crimped grooves 34 are arranged opposite each other and located on the same cross section of the snake body 33 along the axial direction; for example, one of the two crimped grooves 34 is located on the left side and the other is located on the right side.

[0058] The crimped steel pipe 10 and the traction steel wire rope 20 are crimped one-to-one, and the two crimping grooves 34 respectively engage and fix a whole formed by the crimped steel pipe 10 and the traction steel wire rope 20. Thus, pulling the left traction steel wire rope 20 will cause the snake to bend to the left, and pulling the right traction steel wire rope 20 will cause the snake to bend to the right, achieving flexible control of the snake.

[0059] Furthermore, such as Figure 4 As shown, the first end 31 is provided with a connecting ear 35 disposed opposite to it;

[0060] The crimping groove 34 is located below the connecting ear 35 along the axial direction of the snake-bone body 33. This facilitates the routing and wiring of the endoscope module's connection cables, data cables, and other cable harnesses.

[0061] This specification also provides an endoscope, including the traction rope mounting assembly as described in the above embodiments.

[0062] It should be noted that, in the embodiments of this specification, the use of the terms "comprising" or "including" to describe combinations of elements, components, parts, or steps herein also contemplates embodiments essentially composed of these elements, components, parts, or steps. The use of the term "may" herein is intended to indicate that any described attribute "may" include is optional. Multiple elements, components, parts, or steps can be provided by a single integrated element, component, part, or step. Alternatively, a single integrated element, component, part, or step can be divided into multiple separate elements, components, parts, or steps. The use of "a" or "an" to describe an element, component, part, or step does not imply exclusion of other elements, components, parts, or steps.

[0063] The various embodiments described in this specification are presented in a progressive manner, with each embodiment focusing on its differences from the others. Similar or identical parts between embodiments can be referred to interchangeably. The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the invention and implement it accordingly.
