[0002] There are many complex cavity structures inside the body, such as the gastrointestinal tract, respiratory tract, urinary system, etc. These cavity structures often have multiple bends and branches. When doctors use endoscopes for examination, they need to adjust the direction of the endoscope insertion end to facilitate comprehensive search for lesions. When the specific lesion is found, the endoscope lens needs to be fixed so that the doctor can carefully observe the target area.

[0003] The device that fixes the endoscope lens is an angle lock, which can ensure that the position of the surgical instrument in the endoscope field of view is relatively stable, making it easier for doctors to operate the surgical instrument accurately. After repeated use, the angle lock will be worn, fatigued, and the connection parts of the components will become loose and deformed. If it continues to be used, it is easy to malfunction, which may affect the progress of medical surgery. At present, there is a lack of testing equipment on the market for the service life of endoscope angle locks. Summary of the invention

[0053] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0054] As described in the background art, the lens field of view of the endoscope 9 is fixed by an angle lock (refer to Fig.13 ), the angle lock that fixes the endoscope 9 lens will affect the use of the endoscope 9. For example, during medical examinations or surgical operations, if the endoscope 9 field of view is lost due to the failure of the angle lock, it is easy to cause a safety accident. Therefore, the service life of the angle lock and possible failures need to be controlled within a certain range. The inventor found that there is currently no testing equipment on the market for the service life and failures of the angle lock.

[0055] Based on the above problems, an embodiment of the present invention provides a test device and a test method for an endoscope angle lock. The test device measures the service life of the angle lock and possible failures by simulating multiple uses of the angle lock, which will be described in detail below.

[0056] Please refer to Figure 1 and Figure 2The test equipment of the endoscope angle lock includes a base 1, a rotary drive member 23, a clamping jaw 241, a detection probe 222 and a counter 4. The rotary drive member 23 is arranged on the base 1, the clamping jaw 241 is connected to the output end of the rotary drive member 23, the detection probe 222 is arranged on the outside of the clamping jaw 241, and the counter 4 is connected to the detection probe 222. When testing the angle lock of the endoscope 9, the angle lock and the endoscope 9 are first assembled normally, and then the angle lock handle 90 of the endoscope 9 is clamped by the clamping jaw 241. The rotary drive member 23 drives the clamping jaw 241 to rotate back and forth, and the clamping jaw 241 drives the angle lock handle 90 to rotate, thereby simulating the use process of the angle lock handle 90 of the endoscope 9. The detection probe 222 detects the position of the angle lock handle 90 and transmits the position change information of the angle lock handle 90 to the counter 4. The counter 4 records the number of reciprocating rotations of the angle lock handle 90 until the angle lock fails to lock, thereby testing the service life of the angle lock.

[0057] It is worth mentioning that the various components in the angle lock cooperate to lock the curved guide component at the front end of the endoscope 9, thereby fixing the lens field of view of the endoscope 9. The service life of the angle lock refers to the angle lock being unable to lock and fix the curved guide component at the front end of the endoscope 9 after repeated use. Turning the angle lock handle 90 can drive the various components in the angle lock to move. Therefore, in the embodiment of the present invention, the service life of the angle lock can be measured by turning the angle lock handle 90. The wear and deformation of the various components in the angle lock can be stopped during the test process, and the angle lock can be taken out for inspection, or by operating the locking angle of the angle lock handle 90, the swing amplitude change of the curved guide component at the front end of the endoscope 9 can be compared and checked.

[0058] refer to Figure 3 and Figure 4 The output end of the rotary drive member 23 is close to one side of the endoscope 9. The output end of the rotary drive member 23 is connected to a rotating disk 24. The clamping jaw 241 is installed on the rotating disk 24. When the rotary drive member 23 is working, the rotating disk 24 is driven to rotate, thereby driving the clamping jaw 241 to rotate. In this embodiment, the clamping jaw 241 includes a U-shaped groove, the width of the U-shaped groove is adapted to the width of the angle lock handle 90, and when the clamping jaw 241 moves down and aligns with the angle lock handle 90, the angle lock handle 90 can be clamped in the U-shaped groove, and the rotation of the clamping jaw 241 drives the angle lock handle 90 to rotate. In other embodiments, the clamping jaw 241 can also be other structures, which can be specifically designed according to the shape and size of the angle lock handle 90. The design basis of the clamping jaw 241 is that it can firmly and stably grasp the angle lock handle 90 and is easy to release.

[0059] In order to prevent the surface of the angle lock handle 90 from being scratched when the clamping claw 241 clamps the angle lock handle 90 , a protective body may be provided. The protective body is provided in the U-shaped groove or on the outer surface of the angle lock handle 90 .

[0060] In order to adapt to the rotation of the angle lock with different arc trajectories, the clamping jaw 241 is rotatably mounted on the rotating disk 24, that is, the relative distance between the clamping jaw 241 and the rotating disk 24 remains fixed, but the clamping jaw 241 itself can move along a certain center.

[0061] It should be known that the rotary drive member 23 in this embodiment is a reciprocating rotary drive, and the extreme range of rotation is consistent with the rotation range of the angle lock handle 90. The rotary drive member 23 in this embodiment can be a rotary cylinder or a reciprocating rotary motor; or a steering valve 5 can be provided to connect the steering valve 5 to the rotary drive member 23. When the detection probe 222 detects that the angle lock handle 90 is about to reach its extreme rotation position, the detection probe 222 transmits a signal to the steering valve 5, and the relay in the steering valve 5 controls the rotary drive member 23 to rotate in the opposite direction, thereby realizing a reciprocating rotation action.

[0062] refer to Figure 5 Combined with Figure 1 A first vertical plate 2 is provided on the base 1, and the first vertical plate 2 is provided perpendicular to the upper surface of the base 1. A first fixing seat 25 is fixed to the side of the first vertical plate 2, and a quick clamp 3 is fixed on the first fixing seat 25. The rotary driving member 23 is connected to the quick clamp 3, and the quick clamp 3 drives the rotary driving member 23 to move up and down, so that the clamping claw 241 under the rotary driving member 23 grasps the angle locking handle 90 or leaves the angle locking handle 90.

[0063] Specifically, a guide rail 20 is vertically arranged on the first vertical plate 2, and a slider 21 is arranged on the guide rail 20. The slider 21 can slide along the guide rail 20, and a first mounting plate 22 is fixed on the slider 21. The rotating driving member 23 is connected to the first mounting plate 22, and when the slider 21 slides, it drives the rotating driving member 23 to move.

[0064] refer to Figures 6 to 9 The quick clamp 3 includes a connecting seat 301 , a moving rod 302 , a hinge 303 , an arc block 304 and an operating handle 305 .

[0065] The connecting seat 301 includes a connecting plate 3011, a limiting slide 3012 and a hinge 3013. The limiting slide 3012 and the hinge 3013 are both arranged on one side of the connecting plate 3011, and the other side of the connecting plate 3011 is connected to the first fixing seat 25. The moving rod 302 passes through the limiting slide 3012 and can move up and down along the limiting slide 3012. The lower end of the moving rod 302 is connected to the first mounting plate 22. When the moving rod 302 moves up and down, the first mounting plate 22 and the rotating driving member 23 on the first mounting plate 22 move up and down synchronously.

[0066] The hinge 303 includes two identical hinge pieces 3031, which are arranged in parallel and spaced apart. A plurality of holes are provided on the two hinge pieces 3031, one of which is plugged with a first hinge column 3032, the other is plugged with a second hinge column 3033, and the remaining holes are plugged with connecting columns 3034, so as to connect the two hinge pieces 3031 together. The first hinge column 3032 also passes through the hinge portion 3013 of the connecting seat 301, so that the entire hinge 303 is rotatably matched with the hinge portion 3013. The second hinge column 3033 also passes through the arc block 304, so that the arc block 304 can rotate around the second hinge column 3033. The connecting column 3034 also passes through one end of the operating handle 305, and the operating handle 305 is fixedly connected to the connecting column 3034, and relative rotation does not occur.

[0067] The lower end of the arc block 304 is bifurcated to form a plug-in cavity 3041. The upper end of the moving rod 302 is arranged in the plug-in cavity 3041. At the same time, the moving rod 302 and the arc block 304 are rotatably connected together through a latch. The arc block 304 has a convex arc surface, and the side wall of the operating handle 305 rolls with the arc surface of the arc block 304. When the operating handle 305 is rotated upward, the operating handle 305 rolls around the arc surface of the arc block 304 and pushes the arc block 304 to rotate around the latch at the upper end of the moving rod 302. At the same time, the hinge 303 rotates around the first hinge column 3032, and the lower part of the hinge 303 moves upward with the operating handle 305. The arc block 304, which is rotatably connected to the second hinge column 3033, also moves upward while rotating, driving the moving rod 302 to move upward, thereby driving the first mounting plate 22 to move upward.

[0068] A suspension rod 221 is also fixed to the side of the first mounting plate 22, and a detection probe 222 is provided at the lower end of the suspension rod 221. The detection probe 222 is used to detect the position of the angle lock handle 90, so as to determine the number of reciprocating rotations of the angle lock handle 90. In this embodiment, the detection probe 222 can be a distance sensor, and a predicted distance is set at the same time. When the angle lock handle 90 rotates outside the predicted distance, a signal is transmitted to the counter 4. The counter 4 records the number of signals transmitted by the detection probe 222, which is the number of reciprocating rotations of the angle lock handle 90. Of course, in other embodiments, other forms can also be used to record the number of reciprocating rotations of the angle lock handle 90.

[0069] refer to Figures 10 to 12 A fixed positioning component is provided on the base 1, and the fixed positioning component is used to fix the endoscope 9 to the base 1, so as to facilitate the test operation of the angle lock handle 90 and improve the test accuracy.

[0070] In this embodiment, the fixed positioning assembly includes a holder 6 and a pressing block 72. The holder 6 is mounted on the base 1. The holder 6 is provided with a clamping cavity 60. The endoscope 9 is clamped in the clamping cavity 60. The pressing block 72 is arranged at the upper part of the endoscope 9 and is used to compress the endoscope 9, so as to position and fix the endoscope 9. The holder 6 is a block. The shape of the clamping cavity 60 matches the handle of the endoscope 9. When the endoscope 9 is clamped in the clamping cavity 60, it will not shake or move. At the same time, a clearance groove 61 is also provided on the holder 6. One end of the branch tube of the endoscope 9 is clamped in the clearance groove 61, so that the endoscope 9 will not move in its axial direction and will not rotate in the radial direction.

[0071] Specifically, a second vertical plate 7 is provided on the base 1, and the second vertical plate 7 is arranged perpendicular to the upper surface of the base 1. A second fixing seat 74 is fixed to the vertical side of the second vertical plate 7. Another quick clamp 3 is installed on the side where the second fixing seat 74 is connected to the second vertical plate 7. The lower end of the moving rod 302 of the quick clamp 3 is fixedly connected to the second mounting plate 70; the second mounting plate 70 is a flat plate and is parallel to the upper surface of the base 1; a connecting rod 71 is vertically connected to the second mounting plate 70, and the upper end of the connecting rod 71 is fixed to The second mounting plate 70, the lower end of the connecting rod 71 passes through the second mounting plate 70 and extends out of the lower surface of the second mounting plate 70, the lower end of the connecting rod 71 is movably connected with a pressure block 72, and the pressure block 72 can move a certain distance along the axial direction of the connecting rod 71; at the same time, a buffer member 73 is arranged between the upper surface of the pressure block 72 and the lower surface of the second mounting plate 70, and the buffer member 73 is sleeved on the connecting rod 71; wherein, the buffer member 73 can be made of a spring, elastic rubber or other polymer materials with good resilience.

[0072] When the pressing block 72 moves downward to press the endoscope 9, at the moment when the pressing block 72 contacts the endoscope 9, the pressing block 72 can move upward along the connecting rod 71 and compress the buffer 73 to prevent the pressing block 72 from moving downward and directly applying a hard downward pressure to the endoscope 9, causing damage to the endoscope 9; the buffer 73 converts the hard downward pressure of the pressing block 72 into a flexible downward pressure, thereby protecting the endoscope 9.

[0073] Of course, the pressing block 72 can also be directly connected to one end of the buffer member 73, and the other end of the buffer member 73 is connected to the connecting rod 71, which can also play a buffering protection role when the endoscope 9 is pressed.

[0074] A guide hole is provided on the side of the second fixing seat 74 away from the second vertical plate 7, and a guide rod 75 is inserted into the guide hole. The guide rod 75 can slide with the guide hole, and the lower end of the guide rod 75 is connected to the second mounting plate 70. When the quick clamp 3 is pressed down, the moving rod 302 pushes the second mounting plate 70 to move downward, and the connecting rod 71 fixed on the second mounting plate 70 also moves downward synchronously. The downward movement of the connecting rod 71 drives the pressing block 72 at its lower end to move downward, thereby pressing the endoscope 9; in the process of the second mounting plate 70 moving downward, the guide rod 75 also slides downward along the guide hole on the second fixing seat 74, and the guide rod 75 guides and stabilizes the downward movement of the second mounting plate 70. It should be known that when the operating handle 305 of the quick clamp 3 is rotated in the opposite direction, the moving rod 302 can drive the pressing block 72 to move upward, thereby moving away from the endoscope 9.

[0075] In other embodiments, the fixing and positioning assembly includes a holder 6 and a binding member, the holder 6 is also mounted on the base 1, the holder 6 is also provided with a clamping cavity 60, the endoscope 9 is clamped in the clamping cavity 60, and the binding member is bound around the endoscope 9 to prevent the endoscope 9 from moving to the end away from the clamping cavity 60. The binding member can be a tape or a rope, and then the endoscope 9 is tied to the holder 6.

[0076] In this embodiment, the test equipment is further provided with a power box 8, which is installed below the base 1. The power box 8 can hold a battery, which can provide power for the counter 4, the steering valve 5, the rotary drive 23, and the detection probe 222 to ensure normal test work.

[0077] In this embodiment, the counter 4 is a digital display counter 4, which can display the number of reciprocating rotations of the angle lock handle 90 in real time. The counter 4 is installed on the base 1 and is electrically connected to the battery. In this embodiment, the model and parameters of the counter 4 are not limited, and a suitable product available on the market can be directly selected.

[0078] In order to detect the degree of wear of the components of the angle lock handle 90 , a torque sensor is connected to the output end of the rotary drive member 23 . The wear of the components of the angle lock handle 90 can be determined by measuring the change in the torque force of the angle lock handle 90 .

[0079] The angle locking handle 90 of the embodiment of the present invention is removed after, for example, five thousand reciprocating rotations, and the angle locking handle 90 is operated to lock it, and the bending part at the front end of the endoscope 9 is driven and observed to see whether it swings and the swing amplitude, so as to estimate the degree of wear and service life of the angle locking handle 90.

[0080] The angle lock testing device of the embodiment of the present invention also has at least the following advantages:

[0081] (1) The reliability of angle lock products can be guaranteed; by simulating the frequent angle adjustment operations of angle locks in actual use, the performance changes after multiple uses can be accurately evaluated, which helps manufacturers ensure that the angle locks shipped can work stably and reliably within the expected service life, avoiding quality problems that may lead to medical accidents or poor user experience.

[0082] (2) The production process of angle locks can be optimized; during the test process, it can be found at which operation stage the angle lock is prone to failure, such as whether a certain component is worn, deformed, or the connection is loose. The production line can improve the production process based on this information, select more suitable materials, or optimize the design and processing accuracy of components, thereby improving product quality.

[0083] (3) Ensure operational safety; after understanding the life of the angle lock, the user can replace it in time when it is close to the end of its service life, avoiding safety accidents caused by sudden failure of the angle lock during critical medical examinations, operations or industrial inspections.

[0084] An embodiment of the present invention further provides a method for testing an angle lock. The method is based on the above-mentioned testing device and comprises the following steps:

[0085] S1: placing an endoscope 9 with an angle lock on a base 1;

[0086] S2: Adjust the angle of the clamping jaw 241 so that the clamping jaw 241 corresponds to the position of the angle locking handle 90 and can clamp the angle locking handle 90;

[0087] S3: The clamping jaw 241 grasps the angle lock handle 90, and the rotary drive member 23 is started. The rotary drive member 23 drives the clamping jaw 241 to rotate back and forth. The detection probe 222 detects the position change of the angle lock handle 90 and transmits the detection signal to the counter 4. The counter 4 records the number of reciprocating rotations of the angle lock handle 90.

[0088] S4: After the angle lock handle 90 has been rotated back and forth for many times, the rotation drive member 23 is turned off, the endoscope 9 is taken out and the angle lock is used to perform a locking operation, and the swing amplitude of the curved guide member at the front end of the endoscope 9 is driven and observed and recorded;

[0089] S5: Re-place the removed endoscope 9 on the base 1, use the clamp 241 to clamp the angle locking handle 90, and use the rotary drive member 23 to drive the angle locking handle 90 to rotate back and forth, and repeat the cycle several times until the angle locking handle 90 cannot lock the curved guide component at the front end of the endoscope 9 when in the locked state.

[0090] The test method can be used to calculate the service life and possible failures of the angle lock. In actual situations, the angle locks are randomly inspected before leaving the factory, and the inspected angle locks are tested using the above test method.

[0091] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
