Description

Technical Field

[0001] This utility model belongs to the technical field of endoscope auxiliary equipment, specifically relating to a detection device that can detect the bending force of an endoscope. Background Technology

[0002] With the development of science and technology, endoscopes have been widely used in the medical field, serving as one of the important tools for examining internal organs. Generally, endoscopes with a flexible insertion section have a curved section at the front end of the insertion section. This curved section can bend as the operator manipulates the endoscope, allowing it to be positioned at a specific angle for easier further manipulation.

[0003] Clinically, after identifying a suspected lesion, the user typically needs to maintain the endoscope at a fixed angle to allow for further detailed observation or biopsy. This requires the user to hold the rotating handle with their thumb to prevent rotation, keeping the endoscope tip in a fixed bent position until the biopsy or further examination is complete. Because detailed observation or biopsy procedures are very time-consuming, this necessitates maintaining the endoscope at a fixed angle for an extended period. Fixed actions can lead to a poor user experience and, in some cases, may even pose medical risks due to user error.

[0004] As can be seen from the above, the amount of force that the operator or doctor needs to apply to control the bending of the endoscope tip during the actual operation is a very important process. If the force required by the endoscope lever during the process is too great, it will make the operator feel uncomfortable and tired. Manually controlling the lever is time-consuming and laborious. It is necessary to test the bending force of the lever before the product leaves the factory to ensure that it is consistent before leaving the factory. Utility Model Content

[0005] The problem this invention aims to solve is: how to test the force of bending levers before the product leaves the factory.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A detection device for detecting the bending force of an endoscope, comprising: Tooling base; A push-pull force gauge, which can be slidably mounted on a tooling base via a sliding component; The sliding component can drive the push-pull force gauge to move in a two-dimensional plane; A guide assembly is disposed on the tooling base and located at the front end of the sliding assembly; the guide assembly is connected to the front end of the push-pull force gauge and is also connected to the lever of the endoscope to be tested; the lever of the endoscope can drive the front end of the push-pull force gauge to move in an arc trajectory on the guide assembly.

[0007] Furthermore, the sliding assembly includes a front slide rail, a side slide rail seat, and a side slide rail. The bottom of the push-pull force gauge is slidably connected to the front slide rail, and the bottom of the front slide rail is connected to the side slide rail through the side slide rail seat. The front slide rail runs along the front-back direction of the fixture base, and the side slide rail is connected to the fixture base along the left-right direction.

[0008] Furthermore, the number of side rails is at least two.

[0009] Furthermore, the guiding assembly includes a guide block connected to the tooling base, the guide block having an arc-shaped guide groove; a guide pin disposed in the arc-shaped guide groove, the guide pin being slidably connected to the arc-shaped guide groove, and the guide pin being connected to the front end of the push-pull force gauge; and a lever connecting block, one end of the lever connecting block being sleeved on the guide pin, and the other end being connected to the lever of the endoscope to be tested.

[0010] Furthermore, the lever connecting block has a two-layer stepped structure.

[0011] Furthermore, a round hole is provided on the top stepped surface of the lever connecting block for fitting onto the guide pin.

[0012] Furthermore, an elongated hole is provided on the bottom step surface for fitting onto the lever of the endoscope to be tested.

[0013] Furthermore, it also includes a product base, which is set on a tooling base, with the rear end of the product base located above the guide block. The product base has a receiving cavity for accommodating the endoscope to be tested.

[0014] Furthermore, it also includes an elbow clamp, which has a fixed base and a clamping part disposed on the top of the fixed base. The fixed base is disposed on the tooling base, and the clamping part can clamp above the product to be tested.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention relates to a device for detecting the bending force of an endoscope. A guide assembly connects to the front end of a push-pull force gauge, which is also connected to the lever of the endoscope under test. Pushing the force gauge causes its front end to move the endoscope's lever in an arc-shaped trajectory along the guide assembly, allowing the force gauge to move synchronously with the lever. Manually moving the force gauge forward and backward tests the maximum force required to bend the lever to the appropriate angle when the endoscope bends downward and upward, respectively. The final force value is displayed on the force gauge. The key feature of this solution is its ability to accurately test the lever's force using simple physical principles, enabling the testing of the lever's bending force before the endoscope leaves the factory, ensuring consistency before shipment. It is low-cost, easy to implement, and convenient to operate. Attached Figure Description

[0018] The technical solution of this utility model will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are not all embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] Combination Figure 1-5 As shown, this utility model provides a detection device for detecting the bending force of an endoscope, comprising: Tooling base 1 is the base of the entire testing device; push-pull force gauge 3 is slidably mounted on tooling base 1. Push-pull force gauge 3 is an instrument that can measure the numerical change of force in real time. A sliding assembly, consisting of a main slide rail 2, a side slide rail seat 5, and side slide rails 4, slidably connects the push-pull force gauge 3 from top to bottom. The bottom of the push-pull force gauge 3 is connected to the main slide rail 2, and the top of the main slide rail 2 is connected to the bottom of the push-pull force gauge 3 body. The main slide rail 2 runs along the front-back direction of the fixture base 1, representing a track that allows movement back and forth along the axis of the product under test 10. The bottom of the main slide rail 2 is connected to the side slide rail seat 5, and the bottom of the side slide rail seat 5 is connected to two side slide rails 4. The two side slide rails 4 are connected to the fixture base 1 along the left-right direction. The side slide rails 4 represent tracks that require changing the lateral movement trajectory when the push-pull force gauge 3 moves along the product's axial direction and also along the product's arc. The side slide rail seat 5 represents a fixed connection seat based on the side slide rails 4.

[0021] A guide assembly is provided on the fixture base 1, located near the front end of the sliding assembly. The guide assembly includes a guide block 6 connected to the fixture base 1, located near the front end of the positive slide rail 2. The guide block 6 has an arc-shaped guide groove 6-1, which ensures the lever 10-1 of the product under test 10 moves along an arc, providing guidance along the arc. A guide pin 7 is disposed within the arc-shaped guide groove 6-1, with its bottom movably connected to the groove and its top movably connected to a lever connecting block 8. A lever connecting block 8 is also included; one end of the lever connecting block 8 is sleeved on the top of the guide pin 7, and the other end is used to connect and fix the lever 10-1 of the product under test 10. Therefore, the lever connecting block 8 can both connect and fix the lever 10-1 of the product under test 10 and connect to the guide pin 7. The front end of the push-pull force gauge 3 is sleeved on the guide pin 7 and located below the lever connecting block 8. The guide pin 7 serves to connect the push-pull force gauge 3 and the lever connecting block 8, and also ensures that the push-pull force gauge 3 and the lever connecting block 8 can rotate along the axis of the guide pin 7. Product base 9 is provided on tooling base 1, and the rear front end of product base 9 is located above guide block 6. Product base 9 is used to accommodate product 10 under test. Product base 9 means that it can ensure the stable placement of product 10 under test and ensure that the connector can be accurately positioned after product 10 under test is placed.

[0022] Product under test 10 refers to the endoscope product to be tested, which can be any model of product under test 10. Here, only one example is used, which has a lever 10-1 at the rear end and a curved part 10-2 at the front end. For example... Figure 2 As shown, the endoscope product has a lever-controlled bending section 10-2, and the lever 10-1 can move along an arc in different directions. Its control method is through external force exerted by the operator. The maximum force of the lever during its movement needs to be tested. The lever 10-1 of the product under test 10 is connected to the lever connecting block 8, thereby connecting the guide assembly to the product under test 10. When the angle of the product under test 10 changes, the lever 10-1 drives the guide assembly to rotate, thereby moving the push-pull force gauge 3, thus enabling the detection of the endoscope's bending force.

[0023] Elbow clamp 11 has its fixing seat mounted on the tooling base 1. The clamping part of elbow clamp 11 can clamp above the product to be tested 10. Elbow clamp 11 is used to stabilize and fix the product to be tested 10 in the vertical direction. It is closed when in use. If it is necessary to remove the product, elbow clamp 11 can be opened.

[0024] Working principle: 1. First, let's understand how the endoscope of the product under test moves. In fact, it can be moved up and down by the lever on the handle, and then the front end can be moved in different ways.

[0025] 2. When testing without an endoscope, the first step is to connect the lever connecting block to the lever of the product. The lever connecting block should be made of a rigid material and should be tightly connected to the lever to minimize gaps and ensure coordinated movement.

[0026] 3. Next, place the product that has been fixed in the above steps directly on the product base, and connect it simultaneously with the 11 elbow clamps to fix the product in the vertical direction, ensuring that there is no shaking during the movement and minimizing the impact of shaking on the test results.

[0027] 4. Once the above products are ready, connect the lever connecting block, guide pin, and front connector of the push-pull force gauge, ensuring free rotation and smooth movement.

[0028] 5. For example Figure 5An angle card 12 is placed at the front end of the endoscope product to ensure that the bending angle at the front end can be observed in real time to see if it meets the required bending angle.

[0029] 5. Once all the above preparations are complete, the test can be conducted. During the test, manually move the push-pull force gauge back and forth. Moving it back and forth will test the maximum force required to bend the lever after the endoscope is bent downwards and upwards to the appropriate angle. The final force value will be displayed on the push-pull force gauge.

[0030] The above technical features constitute the preferred embodiment of this utility model, which has strong adaptability and optimal implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the needs of different situations.

[0031] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
