[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.
[0039] Aiming at the problem that the snake bone assembly and the tubular structure in the related art cannot be stably connected, the present utility model provides an endoscope device.
[0040] The following will describe the embodiments of the present utility model in conjunction with Figures 1 to 5 , describing the embodiments of the present utility model.
[0041] According to an embodiment of the present utility model, as Figures 1 to 5 shown, an endoscope device is provided, including: a snake bone assembly 1, a tubular structure 2, a first clamping member 3, and a first clamping mating member 4.
[0042] Specifically, a cavity 101 is formed inside the snake bone assembly 1; the tubular structure 2 is inserted into the cavity 101; the first clamping member 3 is arranged on the snake bone assembly 1 along a first direction; the first clamping mating member 4 is arranged on the tubular structure 2 and is clamped with the first clamping member 3. By utilizing the clamping cooperation between the first clamping member 3 and the first clamping mating member 4, on the one hand, the connection stability between the snake bone assembly 1 and the tubular structure 2 can be improved, avoiding the detachment of the snake bone assembly 1 and the tubular structure 2 during the use of the endoscope device; on the other hand, compared with connecting the snake bone assembly 1 and the tubular structure 2 by screws, the solution of this embodiment reduces the number of parts used, simplifies the structure of the endoscope device, thus improving the assembly efficiency of the endoscope device and reducing the production cost of the endoscope device.
[0043] It should be noted that the first clamping member 3 in this embodiment can be set on the side wall of the snake bone assembly 1 in advance, or can be formed by externally pressing the side wall of the snake bone assembly 1 during the assembly process. The following describes some setting forms of the first clamping member 3 in combination with specific examples:
[0044] In one example, since the wall thickness of the side wall of the connection part 201 between the snake bone assembly 1 and the tubular structure 2 is relatively thin, applying a certain external force at the position of the side wall of the snake bone assembly 1 corresponding to the first clamping mating member 4 can cause the side wall of the snake bone assembly 1 to extend towards the direction where the first clamping mating member 4 is located, so as to form the first clamping member 3 that can be clamped with the first clamping mating member 4.
[0045] In another example, in order to ensure full contact between the first clamping member 3 and the first clamping mating member 4, a clamping block can be set at the position of the outer side wall of the snake bone assembly 1 corresponding to the first clamping mating member 4, that is, a certain thickening treatment can be done at this position. With such a setting, when a certain external force is applied to this position, the first clamping member 3 can fully extend into the first clamping mating member 4, improving the connection strength between the two, and further ensuring the connection stability between the snake bone assembly 1 and the tubular structure 2.
[0046] In yet another example, in order to ensure sufficient contact between the first snap member 3 and the first snap mating member 4, an elastic member can be provided at a position on the inner sidewall of the snake bone assembly 1 corresponding to the first snap mating member 4. Specifically, one end of the elastic member is fixed to the inner sidewall of the snake bone assembly 1, and the other end is inclined away from the tubular structure 2. It should be noted that during the process of the snake bone assembly 1 sleeving the tubular structure 2, the part of the tubular structure 2 without the first snap mating member 4 will first abut against the elastic member. At this time, the elastic member will be squeezed against the inner sidewall of the snake bone assembly 1 to avoid interfering with the movement of the tubular structure 2. As the tubular structure 2 moves, when the first snap mating member 4 is located at the position of the elastic member, the elastic member will return to its initial state (inclined away from the tubular structure 2) under the action of its own elastic deformation force. Therefore, the end of the elastic member away from the snake bone assembly 1 will automatically be snapped into the first snap mating member 4, thereby connecting the snake bone assembly 1 to the tubular structure 2.
[0047] It should be added that the first snap mating member 4 in the above example can be, but is not limited to, a groove and a through hole.
[0048] In some embodiments, the end of the first snap member 3 away from the snake bone assembly 1 extends out of the first snap mating member 4 and abuts against the inner sidewall of the tubular structure 2. It can be understood that when the first snap member 3 and the first snap mating member 4 are in a snapped state, abutting the first snap member 3 against the inner sidewall of the tubular structure 2 can improve the connection strength between the first snap member 3 and the first snap mating member 4, thereby reducing the probability of loosening or detachment between the snake bone assembly 1 and the tubular structure 2.
[0049] In some embodiments, the endoscope device further includes a second snap member 5 and a second snap mating member 6. The second snap member 5 is spaced apart from the first snap member 3 and is disposed on the snake bone assembly 1 along a second direction; the second snap mating member 6 is disposed on the tubular structure 2 and is snapped with the second snap member 5, and the first direction and the second direction are disposed at an angle. By providing the second snap member 5 and the second snap mating member 6, the contact area between the snake bone assembly 1 and the tubular structure 2 in the connected state can be increased, and the connection stability between the two can be improved.
[0050] In some embodiments, the shape of the snake bone assembly 1 is cylindrical, the first direction is the circumferential direction of the snake bone assembly 1, and the second direction is the axial direction of the snake bone assembly 1. Designing the snake bone assembly 1 to be cylindrical can reduce the difficulty and cost of production and manufacturing. Further, arranging the first clamping member 3 along the circumferential direction of the snake bone assembly 1 and arranging the second clamping member 5 along the axial direction of the snake bone assembly 1 can prevent relative displacement between the tubular structure 2 and the snake bone assembly 1 in two directions (the circumferential and axial directions of the snake bone assembly 1), thereby improving the connection stability between the tubular structure 2 and the snake bone assembly 1. It can be understood that, in order to simplify the complexity of the preparation process, the shape of the cavity 101 can also be set to be cylindrical.
[0051] It should be noted that Figure 1 the circumferential direction of the snake bone assembly 1 is represented by the direction of A shown in Figure 1 and the axial direction of the snake bone assembly 1 is represented by the direction of B shown in
[0052] In some embodiments, at least two relatively arranged first clamping members 3 are provided on the snake bone assembly 1, and at least two relatively arranged second clamping members 5 are also provided on the snake bone assembly 1. Arranging the two first clamping members 3 relatively and arranging the two second clamping members 5 relatively can achieve uniform force between the snake bone assembly 1 and the tubular structure 2, thereby effectively dispersing stress and improving the connection stability.
[0053] In some embodiments, the tubular structure 2 includes a connecting portion 201, the connecting portion 201 is adapted to the shape of the cavity 101 and is disposed in the cavity 101; the first clamping and cooperating member 4 and the second clamping and cooperating member 6 are spaced apart on the side wall of the connecting portion 201. Keeping the shape of the connecting portion 201 adapted to the shape of the cavity 101 can improve the connection strength between the tubular structure 2 and the snake bone assembly 1. Further, arranging the first clamping and cooperating member 4 and the second clamping and cooperating member 6 spaced apart on the side wall of the connecting portion 201 can, on the one hand, disperse stress, and on the other hand, increase the contact points and contact area between the tubular structure 2 and the snake bone assembly 1, improve the connection firmness and stability between the tubular structure 2 and the snake bone assembly 1, and reduce the risk of loosening or falling off.
[0054] In some embodiments, the tubular structure 2 further includes a support portion 202. The size of the support portion 202 is larger than that of the connecting portion 201. A stepped surface is formed at the connection between the support portion 202 and the connecting portion 201, and the stepped surface abuts against one end of the snake bone assembly 1 close to the tubular structure 2. It can be understood that the size of the connecting portion 201 is smaller than that of the support portion 202. On the one hand, it is convenient for the staff to confirm the assembly direction of the tubular structure 2 and the snake bone assembly 1. On the other hand, it is convenient for the installation and positioning of the tubular structure 2 and the snake bone assembly 1, improving the installation convenience. In addition, setting a stepped surface at the connection between the connecting portion 201 and the support portion 202 can form a limiting structure, that is, to prevent the connecting portion 201 from extending excessively into the cavity 101 during the pre-assembly process.
[0055] In some embodiments, a first positioning mark 2011 is provided on the connecting portion 201 and / or the support portion 202, and a second positioning mark is provided on the snake bone assembly 1. When the first positioning mark 2011 and the second positioning mark are in a side-by-side state, the positions of the second engaging member 5 and the second engaging mating member 6 correspond to each other. Arranging the first positioning mark 2011 and the second positioning mark side by side can enable the staff to complete the precise positioning of the second engaging member 5 and the second engaging mating member 6 in a short time, thereby simplifying the assembly process and reducing the assembly time and cost.
[0056] In some embodiments, the first positioning mark 2011 and the second positioning mark are positioning grooves. Setting the first positioning mark 2011 and the second positioning mark as positioning grooves can enable the staff to complete the precise positioning of the second engaging member 5 and the second engaging mating member 6 in a short time while avoiding damage to the snake bone assembly 1 or the tubular structure 2.
[0057] In some embodiments, the shapes of the first engaging member 3 and the first engaging mating member 4 are one of bar-shaped, square, rectangular, and U-shaped. Setting the first engaging member 3 and the first engaging mating member 4 as common shapes such as bar-shaped, square, rectangular, or U-shaped can reduce production costs and improve production efficiency.
[0058] In some embodiments, the endoscope device further includes: an elastic tube 8 and a traction rope 7. Specifically, at least one elastic tube 8 is disposed inside the tubular structure 2, and at least one traction rope 7 is provided corresponding to the elastic tube 8 one by one and sequentially passes through the cavity 101 and the elastic tube 8. Through the combined design of the traction rope 7 and the elastic tube 8, it can enable the staff to more conveniently control the bending direction and position of the endoscope device, improving the operation accuracy and convenience.
[0059] It can be understood that the number of the elastic tubes 8 in this embodiment may be, but is not limited to, two, three, or four, and can be specifically adjusted according to design requirements. In this regard, the present utility model does not make specific limitations. Similarly, the number of the traction ropes 7 can be adjusted accordingly according to the setting of the elastic tubes 8, which will not be elaborated here.
[0060] It should be noted that the elastic tube 8 in this embodiment can be a spring tube or a medical corrugated tube. It can be understood that both the spring tube and the medical corrugated tube have good flexibility and bendability, and can effectively adapt to various bending states of the snake bone assembly 1.
[0061] In the assembly process of the snake bone assembly 1 and the tubular structure 2 in some embodiments is as follows:
[0062] Insert the connecting portion 201 of the tubular structure 2 into the cavity 101 of the snake bone assembly 1, and gently rotate the tubular structure 2 to make the position of the first snap-fitting member 4 correspond to that of the first snap member 3 on the snake bone assembly 1; then apply a certain external force to the first snap member 3 to bend it towards the direction where the first snap-fitting member 4 is located and extend it into the first snap-fitting member 4; continue to rotate the tubular structure 2 to make the first snap member 3 extend out of the first snap-fitting member 4 and abut against the inner side wall of the tubular structure 2, and make the position of the second snap member 5 correspond to that of the second snap-fitting member 6. At this time, the first positioning mark 2011 on the tubular structure 2 and the second positioning mark on the snake bone assembly 1 are arranged side by side. Then apply a certain external force to the second snap member 5 to bend it towards the direction where the second snap-fitting member 6 is located and extend it into the second snap-fitting member 6. In this way, through the mutual cooperation of the first snap member 3 and the first snap-fitting member 4 and the mutual cooperation of the second snap member 5 and the second snap-fitting member 6, the relative displacement between the tubular structure 2 and the snake bone assembly 1 can be restricted in two directions (the circumferential direction and the axial direction of the snake bone assembly 1), ensuring the connection stability between the tubular structure 2 and the snake bone assembly 1.
