[0030] like Figure 1 and Figure 2 As shown, an adjusting device 100 provided in one embodiment of the present invention includes a fixing assembly 10 , a first adjusting member 20 and a steering mechanism 30 .

[0031] The fixing assembly 10 is used to be relatively fixedly connected to an end of the signal line 200 away from the probe.

[0032] The first adjusting member 20 is connected to the fixing assembly 10 so as to be reciprocatably movable along a preset direction, and the first adjusting member 20 is used for being fixedly connected to an end of the protective layer 300 disposed outside the signal line 200 away from the probe.

[0033] The steering mechanism 30 is fixedly arranged relative to the fixing assembly 10 and is used to be fixedly connected to one end of the adjusting wire 400 located between the protective layer 300 and the signal line 200 away from the probe to adjust the angle of the probe connected to the other end of the adjusting wire 400 .

[0034] The preset direction is Figure 2 Up and down directions shown.

[0035] When the pipeline of the endoscope is stored, one end of the signal line 200 is fixed by the fixing assembly 10, and one end of the adjusting wire 400 is fixed by the steering mechanism 30. The other ends of the signal line 200 and the adjusting wire 400 are fixedly connected to the probe, so the signal line 200 and the adjusting wire 400 are relatively fixed. The end of the protective layer 300 disposed outside the signal line 200 away from the probe is fixedly connected to the first adjusting member 20, and the other end of the protective layer 300 is fixedly connected to the probe, and the first adjusting member 20 can reciprocate along a preset direction, so that the protective layer 300 can be movable relative to the signal line 200 and the adjusting wire 400, so that the length of the signal line 200 and the adjusting wire 400 extending into the protective layer 300 can be adjusted, thereby preventing the signal line 200 and the adjusting wire 400 from being broken when stored and entangled, and preventing the video signal from being unable to be transmitted due to the breaking of the signal line 200 and the probe steering from being unable to be adjusted due to the breaking of the adjusting wire 400.

[0036] It should be noted that the protective layer 300, the adjusting wire 400 and one end of the signal line 200 are all fixedly connected to the probe, that is, the protective layer 300, the adjusting wire 400 and the ends of the signal line 200 are relatively fixed, and the other ends of the signal line 200 and the adjusting wire 400 protrude from the protective layer 300. When the winding is retracted, the steering mechanism 30 does not operate, so the other ends of the signal line 200 and the adjusting wire 400 are relatively fixed and fixed relative to the fixed component 10.

[0037] When storing and winding, the first adjusting member 20 is moved along a preset direction, and the first adjusting member 20 drives the end of the protective layer 300 away from the probe to move toward the end of the signal line 200 and the adjusting wire 400 away from the probe, so that the length of the signal line 200 and the adjusting wire 400 extending into the protective layer 300 can be increased, thereby avoiding excessive stretching of the signal line 200 and the adjusting wire 400 when storing and winding.

[0038] At the same time, it needs to be further explained that the protective layer 300, the adjustment wire 400 and one end of the signal line 200 are all fixedly connected to the probe so as to be relatively fixed, but not completely fixed. When the protective layer 300 moves with the first adjustment member 20, the probe will also move accordingly to prevent the protective layer 300 from being over-stretched.

[0039] In addition, it can be understood that the protective layer 300 in the above embodiment is a steel mesh wound around the adjusting wire 400 and the signal line 200, and the number of the adjusting wires 400 usually includes four, which are used to drive the probe to turn in four directions.

[0040] In some embodiments, the adjusting device also includes a second adjusting member 40, which is rotatably connected to the fixed component 10 around a first rotation axis parallel to a preset direction, and is matched with the first adjusting member 20. The second adjusting member 40 can drive the first adjusting member 20 to move back and forth along the preset direction during rotation around the first rotation axis.

[0041] Thus, the operator only needs to rotate the first adjusting member 20 to make the first adjusting member 20 reciprocate along the preset direction to adjust the length of the signal line 200 and the adjusting wire 400 extending into the protective layer 300. In practical applications, the second adjusting member 40 is threadedly connected to the first adjusting member 20.

[0042] In some embodiments, the fixing assembly 10 includes a first fixing member 11 and a second fixing member 12, the first fixing member 11 is used to be fixedly connected to the end of the signal line 200 away from the probe, the second fixing member 12 is connected to the first fixing member 11, the first adjusting member 20 is connected to the first fixing member 11 so as to be reciprocatingly movable along a preset direction, and one end of the second adjusting member 40 is limited between the first fixing member 11 and the second fixing member 12, and can rotate around a first rotation axis.

[0043] Furthermore, the second fixing member 12 is detachably connected to the first fixing member 11 to facilitate disassembly and assembly. In practical applications, the second fixing member 12 is threadedly connected to the first fixing member 11.

[0044] In some embodiments, the first fixing member 11 has a moving space 111 , one end of the first adjusting member 20 is reciprocatably disposed in the moving space 111 along a preset direction, and the other end of the first adjusting member 20 can extend out of the moving space 111 to be fixedly connected to the protective layer 300 .

[0045] Furthermore, the second fixing member 12 is sleeved on the outside of the first fixing member 11 to form a limit block space together with the first fixing member 11. One end of the second adjusting member 40 is limited in the limit space, and the second adjusting member 40 is rotatable around the first rotation axis. The other end of the second adjusting member 40 extends out of the limit space to facilitate the operator to rotate the second adjusting member 40.

[0046] In some embodiments, the first fixing member 11 includes a first limiting portion 112, a base portion 113, a first rod-shaped portion 114 and a second limiting portion 115 which are fixedly connected in sequence. The first limiting portion 112, the base portion 113, the first rod-shaped portion 114 and the second limiting portion 115 are enclosed to form a cylindrical structure with a moving space 111, and the first limiting portion 112 and the second limiting portion 115 are spaced apart along a preset direction. One end of the first adjusting member 20 extending into the moving space 111 moves back and forth between the first limiting portion 112 and the second limiting portion 115, and the end of the signal line 200 away from the probe is fixedly connected to the first limiting portion 112.

[0047] Furthermore, the second fixing member 12 includes a second rod-shaped portion 121 and a third limiting portion 122 fixedly connected to each other, the second rod-shaped portion 121 is threadedly connected to the outer surface of the first rod-shaped portion 114, one end of the second rod-shaped portion 121 abuts against the base portion 113, and the other end protrudes from the first rod-shaped portion 114, the third limiting portion 122 is fixedly connected to the other end of the second rod-shaped portion 121 protruding from the first rod-shaped portion 114, and is spaced from the second limiting portion 115 in a preset direction to enclose and form the above-mentioned limiting space.

[0048] It can be understood that the first limit portion 112, the second limit portion 115 and the third limit are all ring-shaped, so that the signal line 200, the adjustment wire 400, the first adjustment member 20 and the second adjustment member 40 can pass through. In addition, the first fixing member 11 and the second fixing member 12 are both extended longitudinally along a preset direction, and the signal line 200 and the end of the protective layer 300 away from the probe are both extended along the preset direction to facilitate adjustment.

[0049] In some embodiments, the first adjusting member 20 includes a first connecting portion 21 and an adjusting portion 22 fixedly connected to each other, the first connecting portion 21 is used to be fixedly connected to an end of the protective layer 300 away from the probe, and the adjusting portion 22 is connected to the fixing component 10 so as to be reciprocatable along a preset direction.

[0050] Furthermore, the first connecting portion 21 has a connecting channel passing through its two opposite ends along a preset direction, the adjusting portion 22 has a through hole passing through its two opposite ends along a preset direction and connected to the connecting channel, the protective layer 300 extends into the connecting channel and is fixedly connected to the inner wall of the connecting channel, and the signal line 200 and the adjusting wire 400 extending from the protective layer 300 pass through the through hole to be connected to the fixing component 10 and the steering mechanism 30 respectively.

[0051] In actual application, the inner wall of the first rod-shaped portion 114 is provided with a stop groove extending longitudinally along a preset direction, and a stop protrusion matching the stop groove is protruded from the outer side of the adjusting portion 22. The stop protrusion is clamped in the stop groove so that the adjusting portion 22 can move back and forth along the preset direction without rotating with the second adjusting member 40.

[0052] In some embodiments, the first adjusting member 20 also includes a branching portion 23, which is fixedly connected to one end of the adjusting portion 22 away from the first connecting portion 21. The branching portion 23 is provided with a plurality of branching holes, and each adjusting wire 400 passes through a corresponding branching hole and is fixedly connected to the steering mechanism 30.

[0053] It should be noted that when the adjusting steel wire 400 is connected to the steering mechanism 30, the spacing at one end of the four adjusting steel wires 400 connected to the steering mechanism 30 is greater than the spacing when the four adjusting steel wires 400 are in the protective layer 300. Therefore, a branching portion 23 is provided to ensure that the spacing of the multiple adjusting steel wires 400 located on the side of the branching portion 23 toward the adjusting portion 22 is the same as the second spacing when they are in the protective layer 300.

[0054] In practical applications, the line dividing portion 23 is further provided with a central hole for the signal line 200 to pass through, and a plurality of line dividing holes are arranged at intervals around the central hole.

[0055] In some embodiments, the second adjusting member 40 includes a clamping portion 41 and a second connecting portion 42 fixedly connected to each other, the clamping portion 41 is limited in the limiting space, and the second connecting portion 42 protrudes from the limiting space to mate with the first connecting portion 21 protruding from the moving space 111 and the limiting space.

[0056] It can be understood that the first connection part 21 and the second connection part 42 are both cylindrical, and the second connection part 42 is sleeved on the outside of the first connection part 21 extending out of the moving space 111 and is threadedly connected to the first connection part 21 .

[0057] In some embodiments, the adjusting device further comprises a connecting layer, which is disposed between the first adjusting member 20 and the protective layer 300 and is fixedly connected to the first adjusting member 20 and the protective layer 300 respectively, so that the first adjusting member 20 is fixedly connected to the protective layer 300 .

[0058] In practical applications, the connection layer is a glue layer. Glue is applied on the inner wall of the connection channel and / or the outer side of the protective layer 300 , and then the protective layer 300 is extended into the connection channel so that the outer side of the protective layer 300 is bonded and fixed to the inner wall of the connection channel.

[0059] In some embodiments, the distance that the first adjusting member 20 moves back and forth along a preset direction is a preset length, which can be determined according to actual conditions, that is, according to the total length of the protective layer 300 and the winding condition of the protective layer 300 when it is stored, the length by which the internal signal line 200 and the adjusting wire 400 are stretched during winding is determined, and this length is the preset length to ensure that the signal line 200 and the adjusting wire 400 will not be broken during storage and winding.

[0060] In order to facilitate understanding of the technical solution of the present invention, Figure 2 The usage of the adjustment device in the above embodiment is described as follows:

[0061] When the probe is working, the first adjusting member 20 is moved rightward to abut against the second limiting portion 115. At this time, the signal line 200 and the adjusting wire 400 are both tightened, the probe can be adjusted by the adjusting wire 400, and the signal line 200 can obtain the video signal of the probe.

[0062] When storing and winding, the first adjusting member 20 can be moved to the left until it moves to the leftmost end and abuts against the first limiting portion 112. At this time, the length of the signal line 200 and the adjusting wire 400 extending into the protective layer 300 reaches the maximum, which can prevent the signal line 200 and the adjusting wire 400 from being broken when storing and winding.

[0063] In some embodiments, the steering mechanism 30 includes a driving member and a steering member, the driving member is transmission-connected to the steering member and is used to drive the steering member to rotate around a second rotation axis perpendicular to a preset direction, and the adjustment wire 400 is fixedly connected to the steering member.

[0064] Furthermore, the steering mechanism 30 includes two sets of driving components, each driving component includes a driving member and a steering member, and the steering member in each driving component is used to be fixedly connected to one end of the two adjusting wires 400.

[0065] When each steering member rotates in one direction, one of the two adjusting wires 400 connected to the steering member is tightened, while the other of the two adjusting wires 400 is released. When two adjusting wires 400 for adjusting the probe in two opposite directions are connected to the same steering member, the steering member can be rotated back and forth in two directions, thereby realizing the angle adjustment of the probe in two opposite directions.

[0066] In practical applications, each driving assembly includes a driving member and a steering member, the driving member is a motor, and the steering member is a roller, and the end of the adjustment wire 400 away from the probe is fixedly connected to the edge of the roller.

[0067] Based on the above-mentioned adjusting device, the present invention further provides an endoscopy system, comprising the adjusting device in the above-mentioned embodiment.

[0068] Furthermore, the endoscopy system also includes a probe and a signal line fixedly connected to the probe, a plurality of adjustment wires and a protective layer, wherein the protective layer is located outside the signal line, and the plurality of adjustment wires are located between the protective layer and the signal line.

[0069] Among them, the signal line is used to transmit the video signal captured by the probe, the adjustment wire is used to adjust the angle of the probe, and the protective layer provides a protective effect to position multiple adjustment wires outside the signal line.

[0070] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
