[0046] For the mechanical property test of the endoscope, the relevant terms are explained as follows. "Lever" refers to the "handle" on the handle of the endoscope, which is used to operate and control the bending direction and angle of the bendable part of the insertion part. During the operation, the doctor must always operate the lever to adjust the state of the endoscope in the human body. "Life test" refers to the test of the number of bends of the bendable part of the insertion part of the endoscope from one direction to another by repeatedly operating the lever from forward to reverse. "Reliability test" refers to the reliability of the lever, turntable in the handle, snake bone in the insertion part, wire rope, wire sheath tube, head end and other parts within the set test times when the bendable part of the insertion part of the endoscope is repeatedly bent.
[0047] The existing technology has the following defects. For manual testing, there are problems such as low efficiency, poor accuracy and unstable test conditions. For the existing device test, firstly, it can only bend indirectly and passively, which cannot simulate the actual operation situation. Secondly, only one component is measured separately, and there is no test after the whole assembly. The test results cannot reflect the real data. The existing technology does not have an automatic device to directly measure the push and pull force of the finished product.
[0048] In view of the defects of the prior art, this application directly acts on the lever to perform push-pull force tests on the finished soft endoscope. The resistance, lubricity, force transmission, wire rope tension, etc. of the endoscope's own structure can be fully reflected in the test, simulating the actual operation state.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0050] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0052] Because the key of the present application is to provide a device for testing the mechanical properties of the endoscope 01, the specific structure of the endoscope 01 can refer to the prior art and does not belong to the improvement content of the present application.
[0053] The structure of the endoscope 01 is briefly described as follows. The endoscope 01 is a flexible endoscope, as shown in FIG2 , and includes a lever 011 , a gripping handle 012 , a forceps opening 013 , a data power line 014 , an insertion portion 015 , a bendable portion 016 of the insertion portion, and a camera 017 . The movement of the bendable portion 016 of the insertion portion and the camera 017 thereon are controlled by the movement of the lever 011 , and the position change that occurs can be seen by comparing the bendable portion 016 of the insertion portion with the bendable portion 018 shown as a bend.
[0054] In a specific embodiment, the endoscope automatic testing device provided by the embodiment of the present application mainly includes a test bracket 1, a fixture assembly 2, a driving and measuring assembly 3 and a touch and display assembly 4, the fixture assembly 2 is arranged on the test bracket 1, and the fixture assembly 2 is used to position and install the endoscope 01; the driving and measuring assembly 3 is arranged on the test bracket 1, and the driving and measuring assembly 3 is used to drive the lever 011 of the endoscope 01 and measure the push and pull force of the lever 011 in real time when the lever 011 moves; the touch and display assembly 4 is arranged on the test bracket 1, and the touch and display assembly 4 is electrically connected to the driving and measuring assembly 3, and the touch and display assembly 4 is used to set the driving parameters and measurement parameters of the driving and measuring assembly 3, and display the real-time push and pull force of the lever 011 in the form of a force change curve.
[0055] During the use of the endoscope automatic testing device, the endoscope 01 is first installed, and the endoscope 01 is positioned and installed on the clamp assembly 2; then the mechanical properties of the endoscope 01 are tested, the touch and display assembly 4 and the drive and measurement assembly 3 are started, and the drive parameters and measurement parameters of the drive and measurement assembly 3 are set through the touch and display assembly 4. After the setting of the drive and measurement assembly 3 is completed, the lever 011 of the endoscope 01 is driven by the drive and measurement assembly 3 and the push and pull force of the lever 011 during movement is measured in real time, and the real-time push and pull force of the lever 011 is displayed on the touch and display assembly 4 in the form of a force change curve.
[0056] In combination with the above structure and process description, it can be seen that the endoscope automatic testing device has at least the following beneficial effects: the endoscope automatic testing device is used for mechanical property testing of the endoscope 01, and can realize real-time measurement of push and pull forces and display force curves.
[0057] In some cases, as shown in FIG1 , considering the long length of the endoscope 01, in order to better support the endoscope 01, the embodiment of the present application also provides a support seat 9 on the test bracket 1. The support seat 9 is used in combination with the clamp assembly 2, and the support seat 9 is used to effectively support the insertion portion 015 of the endoscope 01, while the clamp assembly 2 mainly supports the gripping handle 012 of the endoscope 01, so that a stable support effect can be provided over the entire length of the endoscope 01.

The lever chuck 32 is clamped and cooperated with the lever 011, so that the servo motor 31 can be used to drive the lever chuck 32 to move, and then drive the lever 011 fixed by the lever chuck 32 to move, thereby realizing the driving effect of the driving and measuring component 3 on the lever 011; at the same time, because it is the servo motor 31 that applies the push-pull force to the lever 011, the push-pull force of the lever 011 during movement can be measured in real time by monitoring the servo motor 31.
[0060] As shown in FIG1 , the endoscope automatic testing device is divided into a table portion and an under-table portion, the fixture assembly 2 is located on the table portion, the servo motor 31 in the driving and measuring assembly 3 is located on the under-table portion, and the lever chuck 32 connected to the servo motor 31 is located on the table portion. The advantage of this arrangement is that the space of the test bracket 1 is fully utilized while keeping the desktop tidy.
[0061] Please continue to refer to Figure 1. The touch and display component 4 uses a touch screen, that is, a display screen with a touch function. The force curve obtained by the endoscope automatic testing device under the mechanical property test of the endoscope 01 can be displayed through the display screen, and the driving parameters and measurement parameters of the driving and measuring component 3 can be set by touch on the display screen.
[0062] Furthermore, the touch and display component 4 also includes control buttons arranged on the display screen, and the control buttons include a start button 41, a stop button 42, and an emergency stop button 43. The endoscope automatic test device provided in the embodiment of the present application adopts an automated design, and can be started by pressing the start button 41; the endoscope automatic test device measures and monitors the push and pull force in real time, and the force curve is more intuitive; the endoscope automatic test device can perform multiple tests at the same time; the endoscope automatic test device has a high degree of integration and can be used as a standard device.
[0063] In some embodiments, the driving parameters of the driving and measuring component 3 include the bending angle, movement speed and number of cycles of the lever 011 , and the measuring parameters of the driving and measuring component 3 include the sampling frequency and measurement accuracy.
[0064] In this embodiment, the endoscope automatic testing device can not only measure the push and pull forces in real time and display the force curve, but also perform parameter settings. By changing the parameters, the bending angle, movement speed, and number of cycles can be adjusted.
[0065] Specifically, the sampling frequency of the driving and measuring component 3 is 5 to 200 times per second, and the measuring accuracy of the driving and measuring component 3 is 0.01 Newton to 1.0 Newton.
[0066] In a specific embodiment, considering that the bending direction of the bendable portion 016 of the insertion part of the endoscope 01 mainly includes bending in the positive direction and bending in the reverse direction, it can also be seen from the bendable portion 018 shown in the two bending places in Figure 2; therefore, the driving and measuring component 3 is configured to drive the lever 011 to move back and forth between the positive direction and the reverse direction. At this time, the touch and display component 4 is used to respectively display the force change curve of the lever 011 in the positive direction and the force change curve of the lever 011 in the reverse direction.

[0069] For example, taking the setting number of times as 50 and the single cycle of 1.0 second as an example, the force curve can be obtained when the real-time number is 14 times. The force change curve of the lever 011 in the positive direction is displayed as a waveform graph, and the maximum push-pull force required in the positive direction is 12.81 N, and the minimum push-pull force required in the positive direction is 12.18 N; the force change curve of the lever 011 in the reverse direction is displayed as another waveform graph, and the maximum push-pull force required in the reverse direction is 12.96 N, and the minimum push-pull force required in the reverse direction is 12.27 N.
[0070] In some cases, in order to further improve the safety of real-time monitoring, the push-pull force range can be set. When it exceeds the range, it will automatically stop and alarm.
[0071] Specifically, the touch and display component 4 is also provided with a push-pull force value range. When the maximum push-pull force required in the positive direction, or the minimum push-pull force required in the positive direction, or the maximum push-pull force required in the reverse direction, or the minimum push-pull force required in the reverse direction exceeds the range, the test is automatically stopped and an alarm is given.
[0072] In some embodiments, the force data during the test of the lever 011 by the driving and measuring component 3 and the touch and display component 4 is saved as a file.
[0073] In this embodiment, by saving the force data as a file, the accuracy and completeness of the data can be ensured, which is convenient for subsequent analysis, comparison and problem diagnosis.
