[0040] See also Figure 1-Figure 5 The utility model provides an endoscope 100, which includes a shell 10, a bending structure (not shown in the figure), a camera structure (not shown in the figure), a light source structure (not shown in the figure), a control wheel structure 20 and a traction line (not shown in the figure); the shell 10 is formed with a travel opening 101; the bending structure is arranged on the shell 10, and the bending structure is used to extend into the human body; the shooting structure and the light source structure are arranged on the bending structure to illuminate and take pictures in the human body to obtain sample pictures about the health status of the human body; the control wheel structure 20 includes a rotating wheel 21 and a handle 22, the rotating wheel 21 is rotatably arranged in the shell 10, one end of the handle 22 is connected to the rotating wheel 21, and the other end of the handle 22 extends out of the shell 10 through the travel opening 101; one end of the traction line is connected to the bending structure, and the other end of the traction line is connected to the rotating wheel 21. Specifically, the travel opening is the range of the handle 22. The handle 22 is moved within the range defined by the travel opening 101, thereby driving the rotating wheel 21 to rotate, thereby pulling the traction line, and the traction line then pulls the bending structure to bend, so that the light source structure and the shooting structure can be illuminated and shot at different angles.

[0041] In some specific embodiments, see Figure 3 and Figure 5 The control wheel structure 20 also includes a toggle portion 23 , which is connected to an end of the handle 22 away from the rotating wheel 21 , so that the user can control the handle 22 through the toggle portion 23 .

[0042] In some specific embodiments, see Figure 2The shell 10 includes a first shell 11 and a second shell 12 covered on the first shell 11. By splitting the shell 10 into the first shell 11 and the second shell 12, it is convenient to install the control wheel structure 20 and the traction line tightly in the shell 10.

[0043] See also Figure 1 , Figure 2 as well as Figure 5 The housing 10 is also formed with a first traction column 102 and a second traction column 103, the first traction column 102 and the second traction column 103 are located in the housing 10, and the travel opening 101 is located between the first traction column 102 and the second traction column 103; the endoscope 100 also includes a shielding belt 30, the shielding belt 30 is tensionedly sleeved on the first traction column 102 and the second traction column 103, and a side belt of the shielding belt 30 close to the travel opening 101 is connected to the handle 22. It should be noted that when the shielding belt 30 is tensionedly sleeved on the first traction column 102 and the second traction column 103, the shielding belt 30 is divided into two side belts by the extension line of the connection line between the first traction column 102 and the first traction column 103, wherein one side belt is close to the travel opening 101, and the other side belt is far away from the travel opening 101.

[0044] In the utility model, the travel opening 101 is located between the first traction column 102 and the second traction column 103. Therefore, the shielding belt 30 tensioned on the first traction column 102 and the second traction column 103 can shield the travel opening 101. In order not to affect the movement of the handle 22, the side belt of the shielding belt 30 close to the travel opening 101 is connected to the handle 22. When the handle 22 moves within the range formed by the travel opening 101, the shielding belt 30 can rotate along the first traction column 102 and the second traction column 103 driven by the handle 22, so as to conform to the movement of the handle 22. The shielding belt 30 in the technical solution can always shield the travel gap without affecting the movement of the handle 22, thereby solving the technical problem in the prior art that foreign matter can easily enter the interior of the endoscope 100 through the travel opening 101 of the handle 22.

[0045] In some specific embodiments, the shielding strip 30 may be a plastic shielding strip or an elastic shielding strip.

[0046] In some specific embodiments, see Figure 5The first traction column 102 and the second traction column 103 are arranged on the first housing 11. The end surface of the first traction column 102 is recessed to form a first connection hole 1021, and the end surface of the second traction column 103 is recessed to form a second connection hole 1031. The second housing 12 is protruded to form a first connection column (not shown in the figure) and a second connection column (not shown in the figure). The first connection column is clamped into the first connection hole 1021; the second connection column is clamped into the second connection hole 1031. Thus, the second housing 12 and the first housing 11 are more tightly covered and connected.

[0047] In some specific embodiments, see Figure 2 and Figure 5 A guide groove 104 is formed on the inner wall surface of the shell 10 adjacent to the stroke opening 101, and the length extension direction of the guide groove 104 is parallel to the length extension direction of the stroke opening 101; the side edge of the side band of the shielding belt 30 close to the stroke opening 101 is arranged in the guide groove 104.

[0048] In this embodiment, by setting a guide groove 104 whose length extension direction is parallel to the length extension direction of the stroke opening 101, the side edge of the side band of the shielding belt 30 close to the stroke opening 101 is set in the guide groove 104. On the one hand, the connectivity between the shielding belt 30 and the shell 10 is improved, and the sealing and shielding performance of the shielding belt 30 on the stroke opening 101 is improved; on the other hand, the trend of the side band of the shielding belt 30 close to the stroke opening 101 is restricted, so that the trend of the side band of the shielding belt 30 close to the stroke opening 101 better matches the stroke opening 101, thereby more closely shielding the stroke opening 101; Figure 2 and Figure 5 As shown, the travel opening 101 is arc-shaped. Based on the fact that the length extension direction of the guide groove 104 is parallel to the length extension direction of the travel opening 101, the guide groove 104 is also arc-shaped; the side edge of the side band of the shielding belt 30 close to the travel opening 101 is set in the guide groove 104, so that the side band is arc-shaped and fits well with the travel opening 101.

[0049] In some specific embodiments, there are two guide grooves 104, and the two sides of the shielding belt 30 close to the travel opening 101 are respectively located in the two guide grooves 104. That is, the two guide grooves 104 respectively accommodate the two sides of the shielding belt 30 close to the travel opening 101, further improving the sealing and shielding performance of the shielding belt 30; by limiting the two sides, the trend of the shielding belt 30 close to the travel opening 101 is ensured to be more stable and regular.

[0050] In some specific embodiments, the travel opening 101 is formed by the first shell 11 and the second shell 12 , one of the two guide grooves 104 is formed by the first shell 11 , and the other one is formed by the second shell 12 .

[0051] In some specific embodiments, see Figure 5 , the first traction column 102 and the second traction column 103 are both located in the length extension direction of the guide groove 104. That is, the first traction column 102, the guide groove 104, and the second traction column 103 are located in the same direction, so the shielding belt 30 can be smoothly pulled from the guide groove 104 to the first traction column 102, and can also be smoothly pulled from the second traction column 103 to the guide groove 104, thereby improving the smoothness of the rotation of the shielding belt 30.

[0052] In one embodiment, a connection hole (not shown in the figure) is formed on one side of the shielding belt 30 near the travel opening, and the handle 22 is disposed through the connection hole. Thus, the handle 22 is connected to the shielding belt 30, and when the handle 22 is turned, the shielding belt 30 can be driven to move, thereby achieving real-time shielding of the travel opening 101.

[0053] In another embodiment, see Figure 3 and Figure 4 The control wheel structure 20 also includes a fixed column 24 arranged on the handle 22; a first sleeve portion 31 is formed at one end of the shielding belt 30, and a second sleeve portion 32 is formed at the other end of the shielding belt 30, the first sleeve portion 31 is sleeved on the fixed column 24, and the second sleeve portion 32 is wrapped around the first traction column 102 and the second traction column 103 and then sleeved on the fixed column 24.

[0054] That is, one end of the shielding belt 30 is fixedly connected to the fixed column 24 through the first sleeve portion 31, thereby realizing the connection between one end of the shielding belt 30 and the handle 22; the other end of the shielding belt 30 is fixedly connected to the fixed column 24 through the second sleeve portion 32, thereby realizing the connection between the other end of the shielding belt 30 and the handle 22, thereby not only realizing the closed loop of the shielding belt 30, but also realizing the connection between the side belt of the shielding belt 30 close to the stroke opening 101 and the handle 22.

[0055] In some specific embodiments, the end of the fixing column 24 away from the handle 22 is located in the guide groove 104, that is, the fixing column 24 moves along the extension direction of the guide groove 104, and the guide groove 104 limits the moving direction of the fixing column 24. The fixing column 24 is connected to the handle 22, which also limits the rotation direction of the handle 22, thereby supporting the handle 22 to rotate more smoothly. In some specific embodiments, see Figure 3 and Figure 4The fixing column 24 includes a first fixing column 241 and a second fixing column 242 which are relatively independently arranged; the first sleeve portion 31 is sleeved on the first fixing column 241, and the second sleeve portion 32 is sleeved on the second fixing column 242. That is, the first sleeve portion 31 and the second sleeve portion 32 are separately fixedly connected, thereby avoiding interference between the first sleeve portion 31 and the second sleeve portion 32.

[0056] In some specific embodiments, see Figure 3 and Figure 4 There are two first fixing posts 241, and the two first fixing posts 241 are respectively arranged on the two opposite sides of the handle 22; there are two first sleeve parts 31, and the two first sleeve parts 31 are arranged at intervals to form a first avoidance gap 301, and the first avoidance gap 301 is used to avoid the handle 22, so that the two first sleeve parts 31 are respectively sleeved on the two first fixing posts 241. Therefore, the two first sleeve parts 31 can restrict each other, preventing any one of the first sleeve parts 31 from falling off from the first fixing posts 241, and improving the stability of the connection between one end of the shielding belt 30 and the handle 22.

[0057] See also Figure 3 and Figure 4 There are two second fixing posts 242, and the two second fixing posts 242 are respectively arranged on the two opposite sides of the handle 22; there are two second sleeve parts 32, and the two second sleeve parts 32 are arranged at intervals to form a second avoidance gap 302, and the second avoidance gap 302 is used to avoid the handle 22, so that the two second sleeve parts 32 are respectively sleeved on the two second fixing posts 242. Therefore, the two second sleeve parts 32 can restrict each other, preventing any second sleeve part 32 from falling off from the second fixing post 242, and improving the stability of the connection between the other end of the shielding belt 30 and the handle 22.

[0058] See also Figure 2 and Figure 3 The housing 10 is also formed with a rotating hole 105; the control wheel structure 20 also includes a rotating shaft rod 25, the rotating shaft rod 25 is connected to the rotating wheel 21, and the rotating shaft rod 25 is rotatably inserted in the rotating hole 105; thereby realizing the rotatable setting of the rotating wheel 21 relative to the housing 10.

[0059] In some specific embodiments, the rotating shaft rod 25 is connected to the middle portion of the rotating wheel 21, so that when the rotating wheel 21 rotates, the rotating wheel 21 can remain stable.

[0060] In some specific embodiments, see Figure 3One end of the handle 22 located in the housing 10 is connected to the shaft rod 25 . Therefore, when the handle 22 is driven to rotate, the handle 22 drives the shaft rod 25 to rotate, thereby realizing the rotation of the rotating wheel 21 .

[0061] In some specific embodiments, see Figure 5 , the side of the shielding belt 30 away from the stroke opening 101 is sleeved on the rotating shaft rod 25. On the one hand, the side of the shielding belt 30 away from the stroke opening 101 avoids the handle 22; on the other hand, the shielding belt 30 maintains a certain tension; on the other hand, when the handle 22 drives the shielding belt 30 to rotate, the rotating shaft rod 25 also rotates, and the rotation of the rotating shaft rod 25 is used to comply with the rotation of the shielding belt 30, so that the rotation of the shielding belt 30 is smoother.
