[0033] 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.

[0034] 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.

[0035] 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.

[0036] like Figures 1 to 4 As shown, the rotary wheel proposed in this utility model includes a rotary wheel body 1 and at least one set of fixing components.

[0037] The wheel body 1 is provided with a circumferential traction rope groove 11 and an end-facing fixing groove 12. The wheel body 1 typically has a disc-shaped structure. The circumferential traction rope groove 11 is located on the end face of the wheel body 1 in the thickness direction, and the traction rope 5 can be arranged within the circumferential traction rope groove 11. The end-facing fixing groove 12 is located on the end face of the wheel body 1 in the width direction and is used to arrange fixing components. The circumferential traction rope groove 11 is provided with a cable passage 13 that communicates with the end-facing fixing groove 12, and the traction rope 5 can enter the end-facing fixing groove 12 from the circumferential traction rope groove 11 through the cable passage 13.

[0038] The fixing assembly includes a first fixing member 2 and at least one clamping member 3. The first fixing member 2 is installed in the end-facing fixing groove 12. The first fixing member 2 may have a columnar structure or a block structure, and the first fixing member 2 can be installed through mounting holes on the wheel body 1, or installed in the end-facing fixing groove 12 by welding, threaded connection, or integral molding. The first fixing member 2 is provided with a traction rope positioning part 21 extending at least to the surface of the end-facing fixing groove 12. The traction rope positioning part 21 has a hole-like structure or a groove-like structure. The traction rope 5 can pass through the traction rope positioning part 21, thereby positioning the traction rope 5 in the first fixing member 2. When the traction rope positioning part 21 has a groove-like structure, the traction rope positioning part 21 can extend from the top end of the first fixing member 2 to the surface of the end-facing fixing groove 12.

[0039] The clamping member 3 can be used to clamp the traction rope 5 in the traction rope positioning part 21 into the end fixing groove 12. When the fixing assembly includes one clamping member 3, the clamping member 3 can be, for example, a nut or a pin structure; when the fixing assembly includes more than one clamping member 3, the clamping member 3 can be selected from nuts, washers, rings, retaining rings, etc.

[0040] Setting the traction rope positioning part 21 to extend to the surface of the end-fixed groove 12 can effectively prevent the edge of the clamping member 3 or the traction rope positioning part 21 from being tangent or cutting to the traction rope 5 passing through the first fixing member 2, thereby preventing the traction rope 5 from being cut by the clamping member 3 or the traction rope positioning part 21 and causing it to break.

[0041] In practice, the wheel may include one or more sets of fixing components. When the wheel includes multiple sets of fixing components, the multiple sets of fixing components can be arranged in a preset manner, for example, the multiple sets of fixing components are arranged in a ring, and the traction rope 5 passes through each set of fixing components in sequence.

[0042] In practical applications, the wheel may also include a rotating shaft 6. The rotating shaft 6 can be mounted on the wheel body 1 through a rotating shaft connection hole provided on the wheel body 1, or the rotating shaft 6 can be fixed to the wheel body 1 by integral molding. The drive mechanism (e.g., an angle trigger) drives the wheel body 1 to rotate through the rotating shaft 6, thereby driving the traction rope 5 fixed on the wheel body 1 to move, realizing the effect of manipulating the bending mechanism (e.g., a snake bone mechanism), and achieving the purpose of controlling the bending direction and angle of the endoscope lens.

[0043] The swivel provided by this utility model uses a combination of a first fixing member 2 and a pressing member 3 to press and fix the traction rope 5 into the end positioning groove 12 on the swivel body 1. The traction rope 5 has a good fixing effect, which can take into account both firmness and stability, and the traction rope 5 is not easy to fall off the swivel.

[0044] In one embodiment of the wheel of this utility model, the fixing component includes a clamping member 3, which is a nut. By engaging the nut with the threaded connection of the first fixing member 2, the position of the clamping member 3 on the first fixing member 2 can be easily adjusted, thereby pressing the traction rope 5 in the traction rope positioning part 21 into the end-facing fixing groove 12.

[0045] In one embodiment of the wheel of this utility model, the fixing component includes two clamping parts 3, which are a nut and a washer, respectively. Through the cooperation of the nut and the washer, the traction rope 5 in the traction rope positioning part 21 can be safely and stably pressed into the end fixing groove 12.

[0046] In one embodiment of the rotary wheel of this utility model, in order to improve the reliability of the rotary wheel structure, the first fixing member 2 is integrally formed with the rotary wheel body 1.

[0047] In one embodiment of the rotary wheel of this utility model, the edges of the cable routing opening 13 and / or the traction rope positioning part 21 are chamfered. Providing chamfers at the edges of the cable routing opening 13 or the traction rope positioning part 21 effectively prevents the edges of the cable routing opening 13 or the traction rope positioning part 21 from being tangent to or cutting into the traction rope 5, thereby preventing the traction rope 5 from being cut by the edges of the cable routing opening 13 or the traction rope positioning part 21 and thus breaking.

[0048] In one embodiment of the rotary wheel of this utility model, the rotary wheel further includes a second fixing member 4. The second fixing member 4 is installed in the endoscopic fixing groove 12, and the second fixing member 4 is provided with a circumferential traction rope positioning groove 40. The second fixing member 4 may have a columnar structure or a block structure, and the second fixing member 4 may be installed in the endoscopic fixing groove 12 by welding, threaded connection, or integral molding. The circumferential traction rope positioning groove 40 is provided on the end face of the second fixing member 4 in the thickness direction, and the traction rope 5 can be arranged in the circumferential traction rope positioning groove 40.

[0049] By setting the second fixing member 4, the position of the traction rope 5 in the end positioning groove 12 can be adjusted so that the traction rope 5 can pass through the traction rope positioning part 21 without bending, thereby avoiding the traction rope 5 from affecting its service life due to bending.

[0050] In practice, the traction rope 5 can pass through all the first fixing members 2 and the second fixing members 4 in a preset order to achieve stable support of the traction rope 5 in the end fixing groove 12.

[0051] The edges of the openings on the circumferential traction rope positioning groove 40 for the traction rope 5 to enter or leave can be chamfered to prevent the traction rope 5 from being cut by the edges of the openings and breaking.

[0052] In one specific embodiment, screws for fixing the shaft 6 to the wheel body 1 may be provided on the second fixing member 4.

[0053] Furthermore, when the wheel includes two sets of fixing components, the second fixing member 4 is located on the side of the fixing components away from the cable routing opening 13. In this embodiment, the wheel includes two sets of fixing components and a second fixing member 4, with two first fixing members 2 located between the cable routing opening 13 and the second fixing member 4. The traction rope 5 passes through the end fixing groove 12 in the order of passing through the cable routing opening 13, one traction rope positioning part 21, the circumferential traction rope positioning groove 40, the other traction rope positioning part 21, and the cable routing opening 13.

[0054] Furthermore, when the wheel includes three sets of fixing components, the three sets of fixing components are arranged in a ring, with the second fixing component 4 located between the three sets of fixing components. In this embodiment, the wheel includes three sets of fixing components and one second fixing component 4. Two first fixing components 2 are located between the cable routing opening 13 and the second fixing component 4. One first fixing component 2 is located on the side of the second fixing component 4 away from the cable routing opening 13. The traction rope 5 passes through the end-facing fixing groove 12 in the following order: cable routing opening 13, one traction rope positioning part 21, one side of the circumferential traction rope positioning groove 40, another traction rope positioning part 21, the other side of the circumferential traction rope positioning groove 40, another traction rope positioning part 21, and the cable routing opening 13.

[0055] Furthermore, in order to arrange the fixing components more rationally, the first fixing member 2 has a columnar structure.

[0056] Furthermore, in order to arrange the second fastener 4 more reasonably, the second fastener 4 has a disc-shaped structure, a disc-like structure (such as a notched disc), or a crescent-shaped structure.

[0057] This utility model also provides a traction rope fixing assembly, such as Figures 2 to 4 As shown, it includes a traction rope 5 and a rotating wheel of this utility model.

[0058] In one embodiment of the traction rope fixing assembly of this utility model, in order to more effectively fix the traction rope 5 to the wheel, the wheel body 1 is provided with a fixing connection area (not shown in the figure), and the traction rope 5 is fixedly connected to the surface of the wheel body 1 in the fixing connection area. The fixing connection can be, for example, welding or gluing.

[0059] The fixed connection area can be flexibly set according to actual needs. For example, the fixed connection area is located between the cable routing port 13 and the first fixing member 2.

[0060] This invention also provides an endoscope that includes the traction rope fixing assembly of this invention. The endoscope described above may be, for example, a laryngoscope.
