[0002] In recent years, the use of endoscopes in hospitals has increased. The selection and design of soft tubing for endoscopes vary greatly, and the user experience varies. Many of the results of endoscope insertion are based on patient experience or doctor feedback. Some existing soft endoscopes have insertion tubes made of soft tubing and structures. The insertion tubes are also equipped with working channels (through surgical forceps, guidewires, etc.), guide wires, steel wires, water and air supply tubes, etc. The designed insertion tubes may have different overall performance due to differences in tube diameter, thickness, material, manufacturing process, etc., which may have different impacts on clinical use.

[0040] like Figure 1 and Figure 3 As shown, this embodiment provides an endoscope insertion tube detection device, comprising a base plate 1, a drive assembly 2, a dynamometer 8, and a fixing assembly 3. Specifically, the drive assembly 2 is mounted on the base plate 1 and is operatively connected to the dynamometer 8. The fixing assembly 3 is mounted on the base plate 1, with the fixing assembly 3 and the dynamometer 8 spaced apart along a first direction. The detection end of the dynamometer 8 is connected to the first end of the insertion tube 10, and the fixing assembly 3 is connected to the second end of the insertion tube 10. The drive assembly 2 is configured to drive the dynamometer 8 to move in the first direction, thereby moving the dynamometer 8 toward or away from the fixing assembly 3.

[0041] When testing the insertion tube 10 of an endoscope, one end of the insertion tube 10 is connected to the detection end of a force gauge 8, and the other end is connected to the fixing assembly 3. The drive assembly 2 drives the force gauge 8 in a first direction. When the drive assembly 2 drives the force gauge 8 away from the fixing assembly 3, the tension state of the insertion tube 10 is measured; when the drive assembly 2 drives the force gauge 8 toward the fixing assembly 3, the compression state of the insertion tube 10 is measured. By driving the force gauge 8 through a certain stroke, the force gauge 8 detects a real-time curve of the thrust or tension. This curve is used to analyze and record the performance of the insertion tube 10, such as delamination, cracking, wrinkling, hemming, flattening, and plastic deformation. In this embodiment, the force gauge 8 is a digital thrust gauge capable of displaying and detecting the thrust or tension value in real time.

[0042] Furthermore, if Figure 1 and Figure 2As shown, the endoscope insertion tube detection device further includes a fixing clamp 4, one end of which is detachably connected to the detection end of the force gauge 8, and the other end is provided with a first clamping opening 44, the sidewalls of which are capable of clamping the insertion tube 10. When the force gauge 8 needs to detect the tensile force applied to the insertion tube 10, one end of the fixing clamp 4 is connected to the detection end of the force gauge 8. In this embodiment, the fixing clamp 4 is provided with a third through hole 43, and the detection end of the force gauge 8 is provided with a threaded column 81. The threaded column 81 extends through the third through hole 43 and is threadedly connected to a nut, thereby connecting the fixing clamp 4 to the detection end of the force gauge 8. The first end of the insertion tube 10 is then clamped by the sidewalls of the first clamping opening 44, thereby connecting the detection end of the force gauge 8 to the first end of the insertion tube 10.

[0043] Preferably, the endoscope insertion tube detection device further includes an adjustment bolt 5. One of the two side walls of the fixing clamp 4 along the second direction is provided with a first through hole 41, and the other is provided with a first threaded hole 42. The adjustment bolt 5 is inserted through the first through hole 41 and threadedly connected to the first threaded hole 42. The adjustment bolt 5 is used to adjust the size of the first clamping opening 44. The side walls of the first clamping opening 44 are spaced apart along the second direction. When the adjustment bolt 5 is tightened, the spacing between the two side walls of the fixing clamp 4 along the second direction is reduced, thereby reducing the size of the first clamping opening 44 and clamping the insertion tube 10. When the adjustment bolt 5 is loosened, the spacing between the two side walls of the fixing clamp 4 along the second direction is increased, thereby increasing the size of the first clamping opening 44 and facilitating the insertion tube 10 to be disengaged from or inserted into the first clamping opening 44. It should be noted that the side walls of the first clamping opening 44 are arranged relative to each other along the second direction. In this embodiment, the first direction is X and the second direction is Y, with the first direction being perpendicular to the second direction.

[0044] Furthermore, if Figure 3 As shown, the endoscope insertion tube detection device further includes a thrust member 6, one end of which is detachably connected to the detection end of the dynamometer 8, and the other end of which is provided with a mounting hole into which the insertion tube 10 can extend. When the dynamometer 8 needs to detect the thrust applied to the insertion tube 10, one end of the thrust member 6 is connected to the detection end of the dynamometer 8, which is provided with a threaded column 81. The end of the thrust member 6, which is closer to the dynamometer 8, is provided with a third threaded hole, which is threadedly connected to the third threaded hole. This allows the thrust member 6 to be connected to the detection end of the dynamometer 8, and the first end of the insertion tube 10 is then inserted into the mounting hole. The mounting hole serves to limit and connect the first end of the insertion tube 10.

[0045] In this embodiment, Figure 1 and Figure 4As shown, the fixing assembly 3 includes a base 31, an adjustment member 32, and a clamping plate 33. The base 31 is connected to the bottom plate 1, and the clamping plate 33 is connected to the base 31 via the adjustment member 32. A second clamping opening 34 is formed between the base 31 and the clamping plate 33. The adjustment member 32 can adjust the size of the second clamping opening 34 so that the sidewalls of the second clamping opening 34 can clamp the insertion tube 10. When the second end of the insertion tube 10 is connected to the fixing assembly 3, the adjustment member 32 increases the size of the second clamping opening 34 so that the second end of the insertion tube 10 can extend into the second clamping opening 34. The adjustment member 32 then decreases the size of the second clamping opening 34 so that the sidewalls of the second clamping opening 34 clamp the insertion tube 10, thereby connecting the second end of the insertion tube 10 to the fixing assembly 3.

[0046] It should be noted that the endoscope insertion tube detection device further includes a rubber sleeve 7, which is mounted on the insertion tube 10. The fixing assembly 3 is capable of clamping the rubber sleeve 7, and / or the detection end of the dynamometer 8 is capable of clamping the rubber sleeve 7. In this embodiment, the first clamping opening 44 and the second clamping opening 34 both extend along a first direction. The first clamping opening 44 and the second clamping opening 34 match the shape of the rubber sleeve 7. The first clamping opening 44 and the second clamping opening 34 respectively clamp the rubber sleeve 7 mounted on the insertion tube 10, providing high versatility and adaptability to insertion tubes 10 of varying diameters. The first clamping opening 44 and the second clamping opening 34 do not leave any clamp marks on the insertion tube 10 after clamping. Furthermore, the first clamping opening 44 and the second clamping opening 34 increase friction during the clamping process, thereby enhancing the clamping force. In this embodiment, the rubber sleeve 7 is C-shaped, and the rubber sleeve 7 can be mounted on the insertion tube 10 through the C-shaped opening.

[0047] 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 second threaded hole 331, the rod portion 3212 is passed through the second through hole 312 and is threadedly connected to the second threaded hole 331, and the elastic member 323 is provided on the end face 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 10, the operator can drive the clamping plate 33 to overcome the elastic force of the elastic member 323 and move it 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 extending the insertion tube 10 into the second 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 second clamping port 34 clamps the insertion tube 10, the clamping force of the second clamping port 34 is equal to the elastic force of the elastic member 323, which is simple to operate and improves detection efficiency. Furthermore, when it is necessary to increase the clamping force on the insertion tube 10, manually rotate the knob portion 3211 to increase the screwing depth of the rod portion 3212 relative to the second 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 second clamping port 34; when it is necessary to reduce the clamping force on the insertion tube 10, simply rotate the knob portion 3211 in the opposite direction.

[0048] 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. The second through hole 312 is provided at the bottom of the receiving groove 311. The spring is sleeved on the rod portion 3212, and one end abuts against the knob portion 3211, and the other end extends into the receiving groove 311 and abuts against the bottom of the receiving groove 311, thereby improving the installation stability of the elastic member 323 and improving the working reliability.

[0049] Further preferably, the adjustment component 32 further includes at least two guide posts 322, and the clamping plate 33 is provided with guide holes 332. The guide posts 322 correspond to the guide holes 332 in a one-to-one manner. One end of the guide post 322 is connected to the base 31, and the other end is passed through the guide holes 332. 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. 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 due to the restraint of the two guide posts 322, thereby improving the movement accuracy and operational convenience of the clamping plate 33.

[0050] Furthermore, the drive assembly 2 includes a motor 21, a bracket 22, and a slider 23. The bracket 22 is connected to the base plate 1. The bracket 22 is provided with a lead screw 24 and a guide rod 25 extending in a first direction. The slider 23 is threadedly connected to the lead screw 24 and slidably connected to the guide rod 25. The slider 23 is connected to the dynamometer 8. The motor 21 is connected to the bracket 22 and is driven to be connected to the lead screw 24. When the motor 21 drives the lead screw 24 to rotate, the lead screw 24 drives the slider 23 to move in the first direction through the thread, thereby driving the dynamometer 8 to move in the first direction. In this embodiment, the drive assembly 2 also includes a connecting plate, which is connected to the top wall of the slider 23. The dynamometer 8 is mounted on the top wall of the connecting plate. In this embodiment, the motor 21 is a stepper motor that accurately controls the displacement of the dynamometer 8.

[0051] Furthermore, the drive assembly 2 also includes a motor control box 26, which includes a power cord 261, a power switch 262 and a controller 263. The motor control box 26 is connected to the motor 21 through wires, and the power cord 261 is connected to a power source. The working state of the motor 21 can be controlled by the power switch 262 and the controller 263.

Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of protection of the present invention.
