Description

Technical Field

[0001] This invention belongs to the field of medical device testing and measurement technology, specifically relating to a hybrid simulation testing device and method for extracorporeal shock wave equipment. Background Technology

[0002] Extracorporeal Shock Wave Therapy (ESWT), utilizing external shock wave devices, is a non-invasive treatment widely used for musculoskeletal disorders such as nonunion fractures and calcific tendinitis. Its therapeutic principle lies in applying high-energy mechanical waves generated by the external shock wave device to the affected area, promoting tissue regeneration and repair through mechanical stimulation. The accuracy and stability of the shock wave therapy device's output energy and pressure parameters are crucial to ensuring treatment efficacy and safety. Therefore, the quantitative characterization and regular monitoring of the device's output parameters are particularly important.

[0003] Currently, the industry's methods for measuring shock wave parameters have the following main drawbacks: The measurement modes are fragmented, and the application scenarios are limited: water-based scanning and solid-based axial energy methods are two incompatible technical approaches. Existing testing devices are typically designed for only one of these methods. This prevents users from simultaneously addressing the clinically relevant needs of "three-dimensional spatial field scanning" and "simulating axial energy in biological tissue" on a single device. Achieving comprehensive evaluation requires purchasing two separate sets of equipment, which is costly and cumbersome to operate.

[0004] The lack of standardization in biological tissue simulation testing: Although the solid medium method mentions the use of biological tissue samples, existing devices lack standardized clamping modules specifically designed for fixing irregular and fragile soft and hard biological tissues (such as muscle and bone). Typically, only simple clamping or manual fixation methods can be used, resulting in uncontrollable sample conditions and making it difficult to achieve direct, reliable, and comparable assessments of the biological effects of shock waves.

[0005] Insufficient equipment compatibility and test repeatability: The implementation devices for both methods generally lack universal clamping and positioning solutions that can adapt to different brands and models of shockwave handles. For the water medium method, the handle is often simply suspended in the water tank, resulting in poor positioning accuracy and stability; for the solid medium method, the handle relies heavily on manual holding, making it impossible to guarantee the uniformity of applied pressure and angle. This leads to test results that heavily depend on the operator's experience, resulting in poor data comparability between different laboratories and different tests, making it difficult to establish a unified standard for evaluating equipment performance.

[0006] In summary, the existing technology has the following shortcomings and challenges: Limited measurement scenarios: Existing devices typically only support one measurement mode, failing to meet the clinically relevant needs of both "three-dimensional spatial field scanning" and "axial energy simulation of biological tissue".

[0007] Lack of biosimulation testing: There is a lack of standardized modules for convenient and reliable fixation and testing of various biological tissue samples (such as muscle and bone), making it difficult to directly assess the biological effects of shock waves.

[0008] Poor compatibility: There is a lack of universal clamping and positioning solutions that can be adapted to different brands and models of shockwave handles.

[0009] Therefore, there is an urgent need in this field for an integrated, multifunctional testing device to solve the above problems. Summary of the Invention

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Example like Figure 1As shown, a hybrid simulation testing device for an extracorporeal shock wave device includes a test platform base 1, on which a height adjustment platform 2 and a single-axis slide rail 4 for mounting a clamping mechanism are arranged side by side. A switching module 3 is arranged on the height adjustment platform 2, and a hybrid measurement mechanism is arranged on the switching module 3. The hybrid measurement mechanism includes two measurement modules, namely a solid medium measurement module and a fluid medium measurement module. The switching module 3 adjusts the positions of the solid medium measurement module and the fluid medium measurement module according to the measurement requirements, so that the solid medium measurement module or the fluid medium measurement module is positioned opposite to the shock wave handle on the clamping mechanism.

[0026] The solid medium measurement module includes a single-axis measuring stage 6, which includes a base plate 7, side plates 8, and a back plate 9. The base plate 7 is mounted on the moving part of the switching module 3. Two side plates 8 are mounted side by side on the base plate 7. The back plate 9 is mounted on the base plate 7 between the two side plates 8. Both side plates 8 have a first guide groove 10 and a second guide groove 11 arranged side by side. The limiting plate of the sample clamp is set in the first guide groove 10 and connected to the fixing plate 14 on the back plate 9 through a first handwheel screw 12 structure. The sample clamp has a second handwheel screw 13 structure for adjusting the clamping state on its side. The second handwheel screw 13 structure is set in the second guide groove 11. The sample clamps on the two side plates 8 are symmetrically arranged.

[0027] The sample clamp in the solid medium measurement module is a serrated plate 34 or a U-shaped clamping frame 35, which is used to adapt to test samples of different sizes. The clamp is rotatably connected to one end of the screw in the second handwheel screw 13 structure. The other end of the screw in the second handwheel screw 13 structure passes through the second guide groove 11 and is equipped with a handwheel, which is used to adjust the clamping state of the sample clamp.

[0028] like Figure 2 As shown, the sample clamp of the solid medium measurement module is equipped with a serrated plate 34, which is used to clamp large solids and is suitable for hard test samples.

[0029] like Figure 3 As shown, the sample fixture of the solid medium measurement module is equipped with a U-shaped clamping frame 35 for clamping small solids. For softer test samples, the U-shaped clamping frame 35 can better clamp the sample, and it is also suitable for hard test samples.

[0030] like Figure 4As shown, the fluid medium measurement module includes a moving detection module and a bottom module; the moving detection module is used to adjust the position of the hydrophone, and includes a three-axis moving component 5 and a rotating component 15. The three-axis moving component 5 includes an X-axis slide rail 501 set on the test platform base 1, a Y-axis slide rail 502 set on the X-axis slide rail 501, and a Z-axis slide rail 503 set on the Y-axis slide rail 502. The rotating component 15 is set on the Z-axis slide rail 503 through a connector, and a hydrophone 16 is set on the rotating component 15. The bottom module includes a fluid medium tank 17 fixed above the height adjustment platform 2 by the movable part of the switching module 3. A circular hole 18 is provided at the center of the fluid medium tank 17 on the side in contact with the shock wave device probe 31. In this embodiment, the liquid medium in the fluid medium tank 17 is water. The inner wall of the fluid medium tank 17 is attached with a PDMS film 19. A limiting groove 20 is provided on the wall of the fluid medium tank 17 in the X-axis direction. The sample rack 22 is slidably set on the limiting groove 20 by a lifting handwheel screw 21 structure. The limiting groove 20 fixes the sample rack 22 during measurement. The sample rack 22 includes a crossbeam 2201 and a U-shaped frame 2202. A floating pressure block 23 is installed in the middle of the crossbeam 2201 by a floating handwheel screw 24 structure. The floating pressure block 23 is connected to an upper clamping block. A lower clamping block 25 is connected in the middle of the U-shaped frame 2202. The lower clamping block 25 is arranged opposite to the upper clamping block for clamping the sample.

[0031] like Figure 5 As shown, the clamping mechanism includes a fixed slide 26 and a limiting slide 27. An axial baffle 28 is provided on the fixed slide 26, and a V-shaped limiting block 29 is provided on the limiting slide 27. The V-shaped limiting block 29 and the upper limiting block 30 are detachably connected. The probe 31 of the shock wave device is located between the V-shaped limiting block 29 and the upper limiting block 30, and the tail end of the shock wave device abuts against the axial baffle 28.

[0032] Both the hydrophone 16 and the flexible film sensor 32 are electrically connected to the data acquisition and processing module. After the hydrophone 16 or the flexible film sensor 32 acquires the dynamic pressure wave signal, it is transmitted to the data acquisition and processing module for data storage and analysis.

[0033] The testing method for the hybrid simulation testing device of the external shock wave equipment, as described above, includes the following specific steps: Step S1: Install the shock wave device on the clamping mechanism, and switch the position of the solid medium measurement module and the fluid medium measurement module by switching module 3 so that the selected measurement module is coaxially aligned with the shock wave device probe 31; Step S2: Fix the sample onto the selected measurement module and align it coaxially with the shock wave device probe 31; Step S3: Move the clamping mechanism and adjust the handwheel controlling the sample position of the measurement module so that the shock wave device contacts the measurement module, start the shock wave device, and collect the dynamic pressure signal in the measurement module; Step S4: Collect dynamic pressure signals and transmit them to the data acquisition and processing module for data storage and analysis.

[0034] When the solid medium measurement module is selected, the solid conductive medium 33 is fixed to the sample before fixing the sample. In this embodiment, the solid conductive medium 33 is a silicon wafer. In step S3, the second handwheel screw 13 is adjusted to clamp the sample connected to the silicon wafer. The sample is positioned opposite the silicon wafer at one end near the shock wave device probe 31. The other end of the sample is attached to the flexible thin film sensor 32. The position of the clamping mechanism is adjusted and the sample position is moved using the first handwheel screw 12 so that the shock wave device probe 31 contacts the silicon wafer.

[0035] When the fluid medium measurement module is selected, the selected fluid medium is degassed water. To avoid air bubbles in the liquid affecting the measurement results, degassed treatment should be performed when selecting other liquid media. In step S1, the circular hole 18 on the fluid medium tank 17 is aligned with the shock wave device probe 31. In step S3, the position of the clamping mechanism is adjusted so that the shock wave device probe 31 extends into the circular hole 18 and contacts the PDMS film. The sample is placed between the lower clamping block 25 and the upper clamping block. The floating handwheel screw 24 is activated to control the floating pressure block 23 to drive the upper clamping block to descend, so that the sample is fixed between the lower clamping block 25 and the upper clamping block. The sample holder 22 is moved to the Y-axis position, and the sample height is adjusted by the lifting handwheel screw 21 so that the sample is coaxial with the circular hole 18. During the measurement, the moving detection module adjusts the position and direction of the hydrophone 16 through the three-axis moving component 5 and the rotating component 15 to achieve vertical acquisition of the shock wave by the hydrophone 16.

[0036] This invention provides a hybrid simulation testing device for extracorporeal shock wave devices. With a single device, the pressure and energy of shock waves generated by extracorporeal shock wave devices of different brands and models can be measured accurately, reliably, and flexibly. Furthermore, a special sample clamp is provided to hold various test samples as needed, thus meeting the current demand for an integrated and multifunctional testing device.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
