Description

Technical Field

[0001] This utility model relates to the technical field of shock wave testing, and in particular to a shock wave testing device. Background Technology

[0002] Extracorporeal shock wave therapy (ESWT) devices are widely used in the medical field, particularly for treating musculoskeletal pain, soft tissue injuries, and promoting bone repair. To ensure the therapeutic efficacy and safety of these devices, shock wave penetration depth testing must be performed before they leave the factory to confirm that the shock waves emitted by the treatment head can effectively penetrate skin, muscles, and other tissues, achieving the therapeutic goal without damaging normal tissue.

[0003] In traditional shock wave depth measurement devices, the positions of the shock wave handle and sensor are difficult to adjust precisely. They can usually only be tested in a preset standard position, and cannot provide flexible adjustment space when it is necessary to test the penetration of different depths and angles.

[0023] Example 1

[0024] Reference Figures 1 to 2A schematic diagram of the overall structure of a shock wave testing device is provided. The shock wave testing device includes a base 100, a support block 101 disposed on the base 100, a sliding block 102 slidably disposed on one side of the support block 101, a clamping member 103 slidably disposed on the sliding block 102, a support rod 104 disposed on the base 100, a counterweight platform 105 slidably disposed on the support rod 104, a weight 106 disposed on the counterweight platform 105, a detection element 107 disposed on the base 100, and a shock wave handle 108 disposed between the weight 106 and the detection element 107. The shock wave handle 108 can release a shock wave to the detection element 107, and the shock wave is tested through the detection element 107. The clamping member 103 fixes the shock wave handle 108. The support block 101 cooperates with the sliding block 102 to adjust the height of the shock wave handle 108, and the clamping member 103 cooperates with the sliding block 102 to adjust the left and right positions of the shock wave handle 108. The clamping component 103 includes a first clamping block and a second clamping block. Both the first and second clamping blocks have slots that mate with the outer shell of the shockwave handle 108. Through its cooperation with the sliding block 102, the clamping component 103 not only secures the shockwave handle 108 but also allows for left-right position adjustment of the shockwave handle 108 by adjusting the position of the sliding block 102, enabling flexible adaptation to different testing positions. The support rod 104 supports the counterweight platform 105, which can slide along the support rod 104 to adjust the height and position of the weights 106, thereby adjusting the static pressure applied to the shockwave handle 108. The weights 106 are placed on the counterweight platform 105, and by changing the number and mass of the weights 106, the static pressure of the shockwave handle 108 is controlled.

[0025] Furthermore, the base 100 is provided with positioning holes 109, which are linearly arrayed at equal intervals on the base 100. The positioning holes 109 are used to adjust the position of the shock wave handle 108 and the detection element 107. The positioning holes 109 can roughly determine the position of the detection element 107, the support block 101, and the support rod 104, allowing the shock wave handle 108 and the pressure sensor to be adjusted to the appropriate position more quickly.

[0026] Furthermore, the support block 101 is provided with a scale 110; the height of the shock wave handle 108 can be measured through the scale 110. The scale 110 is arranged vertically along the support block 101, displaying the specific position of the sliding block 102 relative to the support block 101, thereby measuring the height of the shock wave handle 108. The scale 110 also facilitates recording the height parameters of each test, providing a reference for repeatability experiments and data analysis.

[0027] Furthermore, the support block 101 and the sliding block 102 are connected by a first connector 111. The first connector 111 includes an opening groove 111a formed on the sliding block 102, a sliding protrusion 111b disposed in the opening groove 111a, a sliding protrusion 111b disposed on the sliding protrusion 111b, and an adjustment knob 111d disposed on the sliding block 102. The height of the sliding block 102 can be adjusted by rotating the adjustment knob 111d. The adjustment knob 111d is fixedly connected to the sliding block 102 by threads, and its end is designed with a gear structure that precisely meshes with the sliding protrusion 111b on the sliding protrusion 111b. When the adjustment knob 111d is rotated, the gear drives the sliding protrusion 111b to move, thereby driving the sliding block 102 to rise and fall along the vertical direction of the support block 101, realizing fine adjustment of the height. The adjustment knob 111d features a non-slip design, with a finely textured surface or rubber coating to improve grip for testers. Additionally, the rotation direction of the adjustment knob 111d is clearly indicated by markings such as "+" and "-".

[0028] Furthermore: the sliding block 102 is connected to the clamping member 103 via a second connecting member 112. The second connecting member 112 includes a connecting plate 112a, mounting blocks 112b disposed on both sides of the connecting plate 112a, a threaded rod 112c rotatably disposed on the mounting blocks 112b, and a rotating knob 112d disposed on one side of the threaded rod 112c. The threaded rod 112c is connected to the clamping member 103 via threads. Rotating the rotating knob 112d can control the left and right movement of the clamping member 103. The threaded rod 112c is rotatably mounted in the two mounting blocks 112b via bearings or bushings, enabling it to maintain stable rotation in the axial direction. One end of the threaded rod 112c extends to the outside and is equipped with the rotating knob 112d for easy manual operation. The surface of the threaded rod 112c is provided with precision threads that mesh with corresponding threaded holes on the clamping member 103. By rotating the knob 112d, the threaded rod 112c generates rotational motion, converting the rotational force into linear displacement, thereby driving the clamping member 103 to move in the left and right directions.

[0029] Furthermore, a replaceable treatment head 113 is provided at the end of the shockwave handle 108; the treatment head 113 is connected to the shockwave handle 108 by a thread. The connection between the treatment head 113 and the shockwave handle 108 uses a threaded structure, facilitating the removal and installation of the treatment head 113 from the shockwave handle 108 for different types of treatment heads 113.

[0030] Operating Procedure: Adjust the positions of the support block 101, support rod 104, and detection element 107 as needed. Fix the support block 101 and support rod 104 in a suitable position through the positioning hole 109 on the base 100, and initially align the shockwave handle 108 with the pressure sensor. Install the shockwave handle 108 on the clamping member 103, select an appropriate treatment head 113, and install it at the end of the shockwave handle 108. Rotate the adjustment knob 111d on the support block 101 to adjust the height of the sliding block 102, changing the vertical position of the shockwave handle 108. Use the scale 110 on the support block 101 to determine the position of the sliding block 102, and record the specific height of the shockwave handle 108. Rotate the rotation knob 112d on the mounting block 112b to rotate the threaded rod 112c, adjusting the left and right position of the shockwave handle 108. Place an appropriate amount of weight 106 on the counterweight platform 105 to provide static pressure on the shockwave handle 108. Install the detection element 107 at the designated position on the base 100, ensuring that the detection element 107 is aligned with the treatment head 113 of the shockwave handle 108. Connect a sensor and an oscilloscope to the detection element 107, calibrate the oscilloscope baseline and record the initial values. Adjust the position of the shockwave handle 108 to maintain an appropriate distance between the treatment head 113 and the detection element 107. Turn on the shockwave handle 108 to release a pressure wave at maximum output energy in a single burst, impacting the detection element 107. Record the pressure value on the oscilloscope and the vertical distance from the treatment head 113 to the detection element 107. Add a silicone pad 107d to the detection element 107 and repeat the test, recording the pressure value and the new vertical distance. Based on the recorded test results, calculate the shockwave penetration depth when using a single silicone pad 107d and two silicone pads 107d as a load.

[0031] Beneficial effects: The sliding engagement of the support block 101 and the sliding block 102 allows for fine-tuning of the height of the shockwave handle 108, meeting various experimental needs. The scale 110 on the support block 101 provides a clear height reference, facilitating experimental repeatability and data recording. The clamping member 103 is connected to the sliding block 102 via the second connecting member 112, and the threaded rod 112c engages with the rotating knob 112d, enabling precise adjustment of the left and right positions of the shockwave handle 108, facilitating adaptation to different test points and sensor positions. The base 100 is provided with equidistantly arranged positioning holes 109, allowing for quick adjustment of the positions of the support block 101, support rod 104, and detection element 107. The positioning holes 109 reduce experimental preparation time and make the alignment of the shockwave handle 108 and detection element 107 more convenient, improving experimental efficiency.

The first sliding stage 107b and the second sliding stage 107c can control the forward and backward movement of the sensor relative to the handle, so as to adjust the distance between the sensor and the shock wave handle 108, and to detect and collect data on shock waves at different positions. The mounting platform 107a is equipped with a guide rail structure, and the first sliding stage 107b and the second sliding stage 107c slide in cooperation with the guide rail through sliders.

[0034] The rest of the structure is the same as in Example 1.

[0035] Beneficial effects: The first sliding stage 107b and the second sliding stage 107c can slide freely, allowing testers to adjust the position of the sensor as needed to adapt to different test conditions.
