[0044] In the prior art, the bending fatigue test of the endoscope snake bone mainly relies on manual work. However, this test method has the problem of inaccurate data. Since manual testing is affected by multiple factors such as human factors, testing experience, and fatigue level, its test results often have large errors. In addition, manual testing has uncontrollable factors such as poor repeatability and poor accuracy, and is inefficient.

[0045] To solve the above problems, Figure 1 and Figure 2 As shown, the present embodiment provides an endoscopic snake bone testing device, which is used to test the endoscope snake bone. The endoscope snake bone includes an insertion tube 20 and a snake bone 10. The snake bone 10 is provided with a plurality of wires 30. The snake bone 10 is connected to the insertion tube 20. The plurality of wires 30 are passed through the insertion tube 20. The endoscope snake bone testing device includes a base plate 1, a first fixing component 2, a second fixing component 3 and a wire drawing traction device 4. The first fixing component 2 and the second fixing component 3 are arranged on the base plate 1 at intervals. The first fixing component 2 and the second fixing component 3 are used to fix the two ends of the insertion tube 20; the wire drawing traction device 4 includes a turntable 41 and a driving member 42. The driving member 42 is drivingly connected to the turntable 41. The ends of the two wires 30 away from the snake bone 10 are respectively wound around the turntable 41 in a clockwise and counterclockwise direction; the driving member 42 drives the turntable 41 to rotate reciprocatingly, so that the turntable 41 drives the snake bone 10 to bend reciprocatingly through the wires 30.

[0046] During the test, the two ends of the insertion tube 20 are respectively fixed to the first fixing component 2 and the second fixing component 3, and the two ends of the two wires 30 away from the snake bone 10 are respectively wound around the turntable 41 in the clockwise and counterclockwise directions; at this time, the driving member 42 drives the turntable 41 to rotate back and forth, and the turntable 41 pulls the wire 30, so that the turntable 41 drives the snake bone 10 to bend back and forth through the wire 30, and realizes multiple bending of the snake bone 10, so that the snake bone 10 is subjected to bending fatigue test, and compared with the manual testing method, the method of driving the turntable 41 to rotate by the driving member 42 has high repeatability, the reciprocating bending accuracy of the snake bone 10 is high, and the bending frequency of the snake bone 10 can be controlled, thereby improving the testing efficiency. It should be noted that the bending of the snake bone 10 by pulling the wire 30 is a prior art and will not be described in detail here.

[0047] Optionally, there are two wire drawing and traction devices 4, and the turntables 41 of the two wire drawing and traction devices 4 are respectively connected to two wires 30; one wire drawing and traction device 4 is used to drive the snake bone 10 to bend back and forth along the first direction, and the other wire drawing and traction device 4 is used to drive the snake bone 10 to bend back and forth along the second direction. Through the cooperation of the two wire drawing and traction devices 4, the snake bone 10 can be bent in any direction. In this embodiment, the first direction is Z, the second direction is X, and the third direction is Y. The first direction, the second direction and the third direction are perpendicular to each other.

[0048] In this embodiment, the first wire drawing and traction device 4, the second wire drawing and traction device 4, the first fixing assembly 2 and the second fixing assembly 3 are sequentially arranged in intervals along the third direction; the height of the turntable 41 of the first wire drawing and traction device 4 is higher than the height of the turntable 41 of the second wire drawing and traction device 4. The turntables 41 of the two wire drawing and traction devices 4 are respectively connected to two wires 30, and because the two turntables 41 are of different heights, interference between the wires 30 connected to the two turntables 41 can be prevented.

[0049] Alternatively, if Figure 1-Figure 3 As shown, the rotating disk 41 is provided with a limiting groove 411 along the circumferential side wall, and the wire drawing 30 is partially wound around the limiting groove 411 and the end is fixedly connected to the rotating disk 41. In this embodiment, two fastening screws 412 are connected to the top of the rotating disk 41 and the side away from the first fixing component 2, and the two wire drawing 30 are wound around the limiting groove 411 in opposite directions and then connected to the fastening screws 412. The limiting groove 411 can prevent the wire drawing 30 from detaching from the rotating disk 41, thereby improving the working reliability.

[0050] In this embodiment, the driving member 42 is a motor, and the wire drawing traction device 4 also includes a motor control box 43, which includes a power cord 431, a power switch 432 and a controller 433. The motor control box 43 is connected to the motor through a wire, and the power cord 431 is connected to the power supply. The working state of the motor can be controlled by the power switch 432 and the controller 433. The forward and reverse direction, speed, stroke, etc. of the motor are controlled by designing the parameters of the motor; the bending direction of the other snake bone 10 is driven by controlling the forward and reverse rotation of the motor. Preferably, the motor is a stepping motor to accurately control the bending angle of the snake bone 10. Further, the wire drawing traction device 4 also includes a connecting frame 44, the motor is fixed on the connecting frame 44, the connecting frame 44 is fixed on the bottom plate 1, and the height of the turntable 41 is adjusted by designing the size of the connecting frame 44.

[0051] Optionally, the first fixing component 2 includes a bracket 21 and an angle wheel 22, the bracket 21 is arranged on the bottom plate 1, the angle wheel 22 is rotatably connected to the bracket 21, and the angle wheel 22 is used to fix the insertion tube 20; the first fixing component 2 is provided with an avoidance hole for avoiding the insertion tube 20, and the avoidance hole runs through the bracket 21 and the angle wheel 22. When the test is performed, the end of the insertion tube 20 away from the snake bone 10 is connected to the angle wheel 22, and when the angle wheel 22 rotates, it can drive the insertion tube 20 to twist, so as to test the bending fatigue and bending angle of the snake bone 10 of the insertion tube 20 in a twisted state.

[0052] Furthermore, the first fixing assembly 2 also includes a connecting block 23, which is connected to the angle wheel 22. The connecting block 23 is provided with a first mounting hole 231 and a first clamping groove 232 connected to the first mounting hole 231. The insertion tube 20 is inserted into the first mounting hole 231. The two side walls of the first clamping groove 232 are adjusted at a distance by a first fastener 24 so that the first mounting hole 231 clamps the insertion tube 20. The axis of the first mounting hole 231 is colinear with the rotation axis of the angle wheel 22 to ensure that when the angle wheel 22 rotates, the insertion tube 20 only twists. When the first fastener 24 is loosened, the size of the first mounting hole 231 is large, which is convenient for installing and removing the insertion tube 20; when the first fastener 24 is tightened, the side wall of the first mounting hole 231 clamps the insertion tube 20.

[0053] Preferably, the first fixing component 2 also includes a fastening screw 412, and an annular boss is provided on the side of the bracket 21 facing the angle wheel 22, the angle wheel 22 is rotatably connected to the annular boss, and the angle wheel 22 can move along the axis of the angle wheel 22 relative to the annular boss; a plurality of first threaded holes are provided on the side of the angle wheel 22 close to the bracket 21, the bracket 21 is provided with a first through hole, the fastening screw 412 is passed through the first through hole and can be optionally threadedly connected to a first threaded hole. Among them, the angle wheel 22 is rotatably connected to the annular boss through a bearing. When the angle wheel 22 rotates, the insertion tube 20 is twisted. At this time, the length of the insertion tube 20 is reduced. In order to adapt to the change in length, the angle wheel 22 adaptively moves relative to the annular boss along the axial direction of the angle wheel 22 to prevent the insertion tube 20 from being strained. When the angle wheel 22 rotates to a preset angle, the fastening screw 412 is passed through the first through hole and threadedly connected to the corresponding first threaded hole. On the one hand, it can limit the angle wheel 22 from continuing to rotate; on the other hand, by adjusting the screwing depth of the fastening screw 412, the distance between the angle wheel 22 and the bracket 21 is controlled, so that the insertion tube 20 remains in a straightened state, thereby improving the test accuracy of the insertion tube 20.

[0054] Further preferably, the outer wall of the angle rotating wheel 22 is provided with anti-skid patterns 221. The anti-skid patterns 221 can increase the friction force, facilitate the operator to manually rotate the angle rotating wheel 22, and improve the convenience of operation.

[0055] Furthermore, if Figure 2 and Figure 4 As shown, the second fixing assembly 3 includes a fixing clamp 35, the fixing clamp 35 is provided with a second mounting hole 351 and a second clamping groove 352 connected with the second mounting hole 351, the insertion tube 20 is inserted into the second mounting hole 351, and the two side walls of the second clamping groove 352 are adjusted by the second fastener 36 to adjust the spacing so that the second mounting hole 351 clamps the insertion tube 20, and the axis of the second mounting hole 351 is collinear with the rotation axis of the angle rotating wheel 22. When the second fastener 36 is loosened, the size of the second mounting hole 351 is large, which is convenient for installing and removing the insertion tube 20; when the second fastener 36 is tightened, the side wall of the second mounting hole 351 clamps the insertion tube 20. Furthermore, since the axis of the first mounting hole 231 and the axis of the second mounting hole 351 are both collinear with the rotation axis of the angle rotating wheel 22, after the two ends of the insertion tube 20 are fixed to the first mounting hole 231 and the second mounting hole 351, the insertion tube 20 itself is in a straightened state and will not be bent.

[0056] In this embodiment, the first fastener 24 and the second fastener 36 can be screws, one of the two side walls of the first clamping groove 232 is provided with a through hole, and the other is provided with a second threaded hole, the screw is passed through the through hole and threadedly connected to the second threaded hole, so as to adjust the distance between the two side walls of the first clamping groove 232, and the second clamping groove 352 has the same structure and principle as the first clamping groove 232. The size of the first mounting hole 231 and the second mounting hole 351 is adjustable, and the versatility is high, and it can meet the needs of insertion tubes 20 with different diameters.

[0057] Preferably, the endoscope snake bone testing device also includes a rubber sleeve 5, which is sleeved on the insertion tube 20, and the first fixing component 2 can clamp the rubber sleeve 5, and / or the second fixing component 3 can clamp the rubber sleeve 5. In this embodiment, the first mounting hole 231 and the second mounting hole 351 match the shape of the rubber sleeve 5, and the first mounting hole 231 and the second mounting hole 351 respectively clamp the rubber sleeve 5 sleeved on the insertion tube 20, and the first mounting hole 231 and the second mounting hole 351 will not cause the insertion tube 20 to leave a clamping mark after clamping, and also increase the friction force and the clamping force during the clamping process. In this embodiment, the rubber sleeve 5 is C-shaped, and the rubber sleeve 5 can be sleeved on the insertion tube 20 through the C-shaped opening.

[0058] It should be noted that this embodiment also provides the working steps of the endoscope snake bone testing device, which are as follows:

[0059] Before use, first fix the second fixing component 3 to one end of the base plate 1, then fix the first fixing component 2 to the middle of the base plate 1, arrange and fix the two wire drawing traction devices 4 on the base plate 1 to be in a line with the angle wheel 22, then make the snake bone 10 and the insertion tube 20 in a straight line, fix the transition section connecting the snake bone 10 and the insertion tube 20 in the second mounting hole 351 of the second fixing component 3, fix the other end of the insertion tube 20 in the first mounting hole 231 of the first fixing component 2 and clamp it, pass the four drawing wires 30 through the avoidance hole, and then wind the four drawing wires 30 and fix them on the two turntables 41 of the two wire drawing traction devices 4, adjust the tightness to make the snake bone 10 and the insertion tube 20 in a straight line.

[0060] During the test, the bending direction of the other snake bone 10 is driven by controlling the forward and reverse rotation of the motor, and the twisting state of the insertion tube 20 is defined by controlling the angle of the rotating angle wheel 22. Through a series of combinations, a bending angle test of the insertion tube 20 when it is naturally straightened can be formed, and a bending angle test of the insertion tube 20 with different twisting angles (maximum 120°) can be formed. It can also be formed. The life test of the insertion tube 20 can be formed by multiple bendings under two states.

[0061] Embodiment 2

[0062] The present embodiment provides an endoscopic snake bone testing device. The structure of the endoscopic snake bone testing device provided in the present embodiment is basically the same as that of the first embodiment, and only the structure of the second fixing component 3 is partially different. The present embodiment will no longer repeat the structure that is the same as that of the first embodiment.

[0063] In this embodiment, Figure 5 As shown, the second fixing assembly 3 includes a base 31, an adjusting component 32 and a clamping plate 33. The base 31 is connected to the bottom plate 1. The clamping plate 33 is connected to the base 31 through the adjusting component 32. A clamping opening 34 is formed between the base 31 and the clamping plate 33. The adjusting component 32 can adjust the size of the clamping opening 34 so that the side wall of the clamping opening 34 can clamp the insertion tube 20. When the second end of the insertion tube 20 is connected to the second fixing assembly 3, the size of the clamping opening 34 is increased by the adjusting component 32 so that the second end of the insertion tube 20 can extend into the clamping opening 34, and then the adjusting component 32 reduces the size of the clamping opening 34 so that the side wall of the clamping opening 34 clamps the insertion tube 20, so that the second end of the insertion tube 20 is connected to the second fixing assembly 3.

[0064] Preferably, the adjusting component 32 includes an adjusting knob 321 and an elastic member 323, the adjusting knob 321 is provided with a knob portion 3211 and a rod portion 3212, the base 31 is provided with a second through hole 312, the clamping plate 33 is provided with a third threaded hole 331, the rod portion 3212 is passed through the second through hole 312 and is threadedly connected to the third threaded hole 331, and the elastic member 323 is provided on the end surface of the knob portion 3211 and the second through hole 312 away from the clamping plate 33. Among them, when it is necessary to connect the insertion tube 20, the operator can drive the clamping plate 33 to overcome the elastic force of the elastic member 323 and move in the direction away from the base 31. At this time, the distance between the clamping plate 33 and the base 31 becomes larger, which is convenient for inserting the insertion tube 20 into the clamping port 34, and then loosen the clamping plate 33. The elastic member 323 drives the clamping plate 33 to move in the direction close to the base 31. Through the elastic force of the elastic member 323, when the clamping port 34 clamps the insertion tube 20, the clamping force of the clamping port 34 is equal to the elastic force of the elastic member 323, which is simple to operate and improves the test efficiency. Furthermore, when it is necessary to increase the clamping force on the insertion tube 20, the knob portion 3211 is manually rotated to increase the screwing depth of the rod portion 3212 relative to the third threaded hole 331. At this time, the knob portion 3211 and the side wall of the base 31 compress the elastic member 323, thereby increasing the clamping force of the clamping port 34; when it is necessary to reduce the clamping force on the insertion tube 20, the knob portion 3211 can be rotated in the opposite direction.

[0065] In this embodiment, the elastic member 323 is a spring, and a receiving groove 311 is provided on the side of the base 31 away from the clamping plate 33, and the second through hole 312 is provided at the bottom of the receiving groove 311.

When the clamping plate 33 moves relative to the base 31, the clamping plate 33 can move in one direction under the guidance of the guide posts 322, and when the rod 3212 of the adjustment knob 321 rotates relative to the clamping plate 33, the clamping plate 33 will not rotate relative to the base 31 under the limitation of the two guide posts 322, thereby improving the movement accuracy and operation convenience of the clamping plate 33.
