Description

Technical Field

[0001] This utility model relates to the field of suture testing, and in particular to a fishbone suture external force fracture testing device. Background Technology

[0002] In the medical field, fishbone sutures are an important surgical suture material. Their quality directly affects the surgical outcome and the patient's postoperative recovery. With its unique structure, such as barbs or a fishbone-like texture, fishbone sutures can better fix tissues during suturing, reduce the risk of suture slippage, and improve the stability and reliability of suturing. They have been widely used in various surgical procedures.

[0003] Existing tests for fishbone suture fracture under external force typically involve tensile testing of the suture using a tensile testing machine, followed by abrasion testing to assess its abrasion resistance. However, most current equipment can only test one performance indicator of the suture, requiring the use of different functional equipment for testing. This process is cumbersome, time-consuming, and increases testing costs, resulting in low testing efficiency and significant inconvenience.

[0004] Therefore, it is necessary to design a fishbone suture external force fracture testing device that can test the tensile strength, ductility, maximum stress that it can withstand, and abrasion resistance of sutures, realize multiple tests in combination, eliminate the need to change equipment, improve testing efficiency, and reduce testing costs. Utility Model Content

[0005] To overcome the shortcomings of most current equipment, which can only test one performance index of sutures and requires the use of different functional devices for testing, resulting in cumbersome operation, time consumption, increased testing costs, low testing efficiency, and great inconvenience, this utility model provides a herringbone suture external force fracture testing device that can test the tensile strength, ductility, maximum stress that can be withstood, and abrasion resistance of sutures, achieving multiple tests in combination, eliminating the need to change equipment, improving testing efficiency, and reducing testing costs.

[0006] The technical implementation scheme of this utility model is as follows: a fishbone suture external force fracture testing device, including a test platform, slide rails, a first cylinder, a locking block, a fixing block, a limiting block, a first pressure sensor, a suture sample, an instantaneous testing component, and a friction testing component. The front and rear parts of the test platform are slidably connected to the slide rails. The upper sides of the front and rear parts of the test platform are each connected to the first cylinder. The first cylinder and the processor are electrically connected through a control module. The telescopic ends of the first cylinders are connected to the slide rails on the same side. The sides of the slide rails that are close to each other are slidably connected to the locking blocks. The middle of each locking block is connected to the limiting block. The fixing block is locked onto the limiting block. The sides of the limiting blocks that are far apart from each other are connected to the first pressure sensor. The suture sample is connected between the fixing blocks. The test platform is provided with an instantaneous testing component for instantaneous tensile testing of the fishbone suture. The upper right side of the test platform is provided with a friction testing component for friction testing of the fishbone suture.

[0007] As a further preferred option, all slide rails are U-shaped.

[0008] As a further preferred option, each fixing block has mating holes.

[0009] As a further preferred option, the instantaneous testing component includes a motor, a cam, a connecting block, and a transmission rod. Two motors, one in front and one behind, are connected to the upper part of the test platform. The motors and the processor are electrically connected through a control module. The output shafts of the motors are rotatably connected to the test platform. A cam is connected to the output shaft of each motor. A connecting block is connected to the side of the locking block that is far apart from each other. The connecting blocks are in contact with the test platform. A transmission rod is connected to each connecting block.

[0010] As a further preferred embodiment, the friction test assembly includes a second cylinder, a friction block, and a second pressure sensor. The second cylinder is connected to the upper right side of the test bench. The second cylinder and the processor are electrically connected through a control module. The second pressure sensor is connected to the telescopic end of the second cylinder, and the friction block is connected to the left side of the second pressure sensor.

[0011] As a further preferred option, the friction block is made of nylon.

[0012] This invention has the following advantages: The suture sample is mounted on a limiting block, and the fishbone suture is detected by moving the slide rail in conjunction with the first pressure sensor. The instantaneous breakage of the suture is detected by rotating the cam to push the transmission rod to move and pull it. The wear resistance of the suture is detected by using the second pressure sensor and the friction block. Thus, the tensile strength, ductility, maximum stress that can be withstood and wear resistance of the suture can be detected, realizing the combination of multiple tests without changing the equipment, improving the efficiency of the test and reducing the test cost.

[0020] A device for testing the fracture of fishbone sutures under external force, such as Figures 1-5As shown, the test platform includes a test stand 1, slide rails 2, a first cylinder 3, a locking block 4, a fixing block 7, a limiting block 10, a first pressure sensor 11, a sutured sample 15, an instantaneous testing component, and a friction testing component. The test stand 1 is slidably connected to the slide rails 2 at both its front and rear ends. The slide rails 2 are U-shaped for easy movement. The first cylinders 3 are connected to the upper sides of both the front and rear ends of the test stand 1. The first cylinders 3 and the processor are electrically connected via a control module. The extension and retraction ends of the first cylinders 3 are connected to the slide rails 2 on the same side. The slide rails 2 are close to each other. The card blocks 4 are slidably connected to each side, and the limiting blocks 10 are connected to the middle of each card block 4. The fixing blocks 7 are snapped onto each limiting block 10. Each fixing block 7 has a mating hole for easy fixing. The first pressure sensor 11 is connected to the side of each limiting block 10 that is far apart from each other. The suture sample 15 is connected between the fixing blocks 7. The test platform 1 is provided with an instantaneous test component for instantaneous tensile testing of the fishbone suture. The upper right side of the test platform 1 is provided with a friction test component for friction testing of the fishbone suture.

[0021] like Figure 1 and Figure 2 As shown, the instantaneous testing assembly includes a motor 5, a cam 6, a connecting block 12, and a transmission rod 13. The upper part of the test platform 1 is connected to two motors 5, one in front and one behind. The motors 5 and the processor are electrically connected through a control module. The output shafts of the motors 5 are rotatably connected to the test platform 1. The cam 6 is connected to the output shaft of each motor 5. The connecting block 12 is connected to the side of the locking block 4 that is far apart from each other. The connecting block 12 is in contact with the test platform 1. The transmission rod 13 is connected to the connecting block 12.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, the friction test assembly includes a second cylinder 8, a friction block 9, and a second pressure sensor 14. The second cylinder 8 is connected to the upper right side of the test bench 1. The second cylinder 8 and the processor are electrically connected through a control module. The second pressure sensor 14 is connected to the telescopic end of the second cylinder 8. The friction block 9 is connected to the left side of the second pressure sensor 14. The friction block 9 is made of nylon and has good wear resistance.

[0023] When a force breakage test is required on a fishbone suture, this device can be used. The test platform 1 is brought into contact with the ground, and the suture sample 15 containing the fishbone suture is placed on the test platform 1. The mating hole on the fixing block 7 engages with the limiting block 10 for fixation. Then, the processor activates the first cylinder 3 via the control module. The first cylinder 3 moves the slide rail 2, causing the locking block 4 to move, which in turn moves the first pressure sensor 11 and the limiting block 10, thereby stretching the suture sample 15. This allows for continuous tensile testing of the fishbone suture until it breaks. The first pressure sensor 11 detects the pressure, thereby assessing the tensile strength and ductility of the fishbone suture. The slide rails 2 are U-shaped for easy movement. After detection, the first cylinder 3 reverses its operation, causing the slide rails 2 to move in the opposite direction, which in turn moves the locking block 4 in the opposite direction, causing the first pressure sensor 11 and the limiting block 10 to move and reset in the opposite direction. Then, the fixing block 7 is removed, and the suture sample 15 is removed. The above operation is repeated to install a new suture sample 15. The processor starts the motor 5 through the control module, which drives the cam 6 to rotate and contact the transmission rod 13, pushing the... The transmission rod 13 moves, causing the connecting block 12 to move, pulling the locking block 4 along the slide rail 2, thereby pulling the fixing block 7 to perform instantaneous tensile breakage detection on the suture, and thus detecting the maximum stress that the suture can withstand at any moment. After the detection is completed, the motor 5 reverses its operation, causing the cam 6 to rotate in the opposite direction and reset, and then pushes the locking block 4 to move and reset. Next, the fixing block 7 is removed, and the suture sample 15 is removed. Then, a new suture sample 15 is installed. The processor starts the second cylinder 8 through the control module, and the second cylinder 8 drives the second pressure sensor 14. The friction block 9 is moved left and right to perform a friction test on the suture, observing whether the suture will break. The pressure is detected by the second pressure sensor 14, which in turn detects the friction force, thus enabling the testing of the suture's wear resistance. The friction block 9 is made of nylon, which has good wear resistance, thereby enabling the testing of the suture's tensile strength, ductility, maximum stress it can withstand, and wear resistance. This allows for the combination of multiple tests without the need to change equipment, improving testing efficiency and reducing testing costs. After the test is completed, the second cylinder 8 is turned off, and then the fixing block 7 is removed, allowing the suture sample 15 to be removed.
