DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] The core of the utility model is to provide an extracorporeal shock wave therapy instrument penetration depth measurement device, which uses a handle mounting base to limit the axial position of the control handle to avoid the axial position of the control handle from being offset when the shock wave is generated, thereby significantly improving the measurement accuracy of the penetration depth.
[0028] It should be noted that the silicone pad 01 mentioned in this application document is not limited to a silicone pad, but generally refers to a simulated load used to simulate human tissue.
[0029] The utility model provides an extracorporeal shock wave therapy device penetration depth measurement device, comprising a test frame, the test frame is provided with a standard weight 8, a control handle 7, a silicone pad fixing seat 13 for placing a silicone pad 01, a piezoelectric sensor 14 and a distance measuring device, the test frame is provided with at least two handle mounting seats for mounting the control handle 7, and the handle mounting seats are sleeved outside the shaft neck section of the control handle 7;
[0030] The handle mounting seat includes a fixed seat 5 and a movable seat 11 . The movable seat 11 is detachably connected to the fixed seat 5 so as to jointly form a handle mounting hole for mounting the control handle 7 .
[0031] Among them, the standard weight 8 is pressed onto the top of the control handle 7 to apply positive pressure to the control handle 7. The mass of the standard weight 8 is determined according to the measurement requirements of the penetration depth and is usually set to 2.5 kg. In order to prevent the force direction of the control handle 7 from tilting relative to its axis, it is preferred to provide a handle limit hole at the bottom of the standard weight 8, and the top of the control handle 7 is inserted into the handle limit hole.
[0032] The handle limiting hole can be directly set at the bottom of the standard weight 8, or it can be set on the boss at the bottom of the standard weight 8; the shape of the above-mentioned handle limiting hole is determined according to the shape of the top end face of the control handle 7, and the inner diameter of the handle limiting hole is equal to or slightly larger than the diameter of the top of the control handle 7.
[0033] The control handle 7 is provided with two shaft neck sections with smaller diameters, and the two handle mounting seats of the test frame are preferably matched with the above-mentioned two shaft neck sections respectively; considering that the control handle 7 moves downward under the pressure of the standard weight 8, the height of the handle mounting seat needs to be smaller than the length of the corresponding shaft neck section to reserve sufficient sliding space.
[0034] Of course, the handle mounting seat can also be arranged to slide with the control handle 7 relative to the bottom plate 1 of the test frame. In this case, there is no need to consider the need for reserved sliding space for the up and down sliding of the control handle 7, and the handle mounting seat can be kept in contact with the step surface at the lower part of the shaft neck section of the control handle 7 at all times, which can not only limit the axial position of the control handle 7, but also prevent the force direction of the control handle 7 from deviating from the axial direction.
[0035] In order to facilitate the installation and disassembly of the control handle 7 and the handle mounting seat, the handle mounting seat is designed as a split body, and the handle mounting seat includes at least one fixed seat 5 and at least one movable seat 11, and any fixed seat 5 and any movable seat 11 are detachably connected; for the convenience of assembly, it is preferred to set the handle mounting seat to include only one fixed seat 5 and one movable seat 11.
[0036] The silicone pad fixing seat 13 is arranged below the control handle 7, and one or two silicone pads 01 can be arranged therein to measure the penetration depth under one and two simulated load conditions; the shape and size of the silicone pad fixing seat 13 are determined according to the shape and size of the silicone pad 01 specified for use in the actual penetration depth measurement.
[0037] In order to measure the pressure value after attenuation by the silicone pad 01, a piezoelectric sensor 14 is provided between the silicone pad fixing seat 13 and the bottom plate 1 of the test frame. The type and model of the piezoelectric sensor 14 can be determined according to actual detection needs with reference to existing technology.
[0038] The piezoelectric sensor 14 can be placed directly on the base plate 1, preferably on the sensor fixing seat 15 of the base plate 1, so as to prevent the piezoelectric sensor 14 from moving horizontally relative to the base plate 1 during detection, thereby affecting the measurement accuracy of the piezoelectric sensor 14.
[0039] The distance measuring device is used to measure the distance from the treatment head of the control handle 7 to the piezoelectric sensor 14. In order to save the alignment and adjustment process of the distance measuring device, it is preferably set to be fixed on the test frame; the distance measuring device can be set to a high-precision ruler 10 or a distance measuring sensor to ensure the accuracy of height measurement.
[0040] In this embodiment, the control handle 7 is mounted in two handle mounting seats of the test frame. The handle mounting seats can limit the axial position of the control handle 7, thereby avoiding the axial position of the control handle 7 from being offset when the shock wave is generated, ensuring the accuracy of the pressure on the silicone pad 01 measured by the piezoelectric sensor 14 and the vertical distance from the treatment head to the silicone pad 01 measured by the distance measuring device, thereby significantly improving the measurement accuracy of the penetration depth.
[0041] Preferably, the axis of the control handle 7, the axis of the silicone pad fixing seat 13 and the center of the piezoelectric sensor 14 are collinear to ensure the accuracy of the measurement position of the piezoelectric sensor 14, thereby ensuring the accuracy of the measurement result of the piezoelectric sensor 14.
[0042] Based on the above embodiment, the structure of the handle mounting seat is defined, one end of the movable seat 11 is rotatably connected to the fixed seat 5 through a pin shaft 111, and the other end of the movable seat 11 is connected to the fixed seat 5 through a locking member, which can be specifically set to a fastening bolt, a connecting pin, etc.
[0043] Therefore, when the control handle 7 needs to be installed, the locking piece in the movable seat 11 can be taken out, and the movable seat 11 can be controlled to rotate in a direction relatively away from the fixed seat 5, so that the movable seat 11 makes room for the installation of the control handle 7, and the control handle 7 is placed in the fixed seat 5;
[0044] After the control handle 7 is placed in the fixed seat 5, the movable seat 11 is controlled to rotate in a direction relatively close to the fixed seat 5, and the relative positions of the movable seat 11 and the fixed seat 5 are connected and fixed by a locking piece to prevent the control handle 7 from falling out of the handle mounting seat during the measurement process.
[0045] It should be noted that the above-mentioned pin shaft 111 can also be replaced by a hinge or other similar structure, and the axial direction of the pin shaft 111 can be parallel to the axial direction of the control handle 7 or perpendicular to the axial direction of the control handle 7.
[0046] Please refer to Figure 1The axis of the pin 111 is parallel to the axis of the control handle 7. The locking part includes a ball screw 112 and a butterfly nut 6. The ball screw 112 passes through the mounting hole of the fixed seat 5 and the connecting hole of the movable seat 11 in sequence and is threadedly connected to the butterfly nut 6. The handle mounting seat can be locked by screwing the butterfly nut 6.
[0047] The pin shaft 111 is set vertically. Compared with the horizontal setting of the pin shaft 111, the angle of rotation required for the movable seat 11 when installing and removing the control handle 7 is relatively small, and the operation is convenient; the threaded connection of the butterfly nut 6 and the ball screw 112 is used to connect and fix the movable seat 11 and the fixed seat 5, and the connection structure is simple and the connection strength is high.
[0048] On the basis of the above embodiment, in order to prevent the standard weight 8 and the handle mounting seat from shifting during the lifting process, the test frame includes a base plate 1 and at least two guide shafts 3 perpendicularly arranged on the base plate 1, and the standard weight 8 and the handle mounting seat are both slidably mounted on the guide shaft 3 through a guide sleeve 4.
[0049] The guide shaft 3 is mounted on the bottom plate 1 through the guide shaft fixing seat 2 at the bottom. The bottom plate 1 and the guide shaft 3 constitute the main supporting structure of the test frame. Please refer to Figure 2 , the bottom plate 1 preferably adopts a large plane design to increase the contact area between the test frame and the test table, thereby improving the stability of the test frame;
[0050] A weight fixing plate 9 is preferably provided on the top of the guide shaft 3. The weight fixing plate 9 is used to limit the standard weight 8 to prevent it from sliding upward and separating from the guide shaft 3. The weight fixing plate 9 can be detachably connected to the guide shaft 3 by common connecting parts such as fastening bolts and connecting pins.
[0051] The number of guide shafts 3 is not limited and can be as follows Figure 1 The setting shown is two, and it can also be set to multiple; considering the size and production cost of the test frame, it is preferred to set the number of guide shafts 3 to two, and the two guide shafts 3 are symmetrically distributed about the vertical symmetry plane of the control handle 7.
[0052] On the basis of the above embodiment, in order to further improve the measurement accuracy, the silicone pad fixing seat 13 includes an upwardly extending protective cover 12, the height of the protective cover 12 is greater than the height of the two layers of silicone pads 01, and the inner diameter of the protective cover 12 is greater than the diameter of the silicone pad 01 after being compressed by impact.
[0053] The protective cover 12 can be as Figure 4 As shown, it is fixed to the side plate of the silicone pad fixing seat 13 by connecting screws; it can also be set as an integrated structure with the silicone pad fixing seat 13 to simplify the assembly process between the protective cover 12 and the silicone pad fixing seat 13;
[0054] The height of the protective cover 12 needs to be greater than the height of the two layers of silicone pads 01, and its inner diameter must be greater than the diameter of the silicone pad 01 after being compressed by the shock wave. This can not only ensure that the protective cover 12 has a limiting effect on the silicone pad 01 and reduces the horizontal movement of the silicone pad 01 when it is under pressure, but also avoid the protective cover 12 restricting the stretching process of the compressed silicone pad 01, thereby preventing the protective cover 12 from affecting the test results.
[0055] In this embodiment, the protective cover 12 is used to limit the horizontal displacement of the silicone pad 01 when it is under pressure, ensuring that the test position during each test is relatively stable, thereby improving the accuracy of the penetration depth measurement;
[0056] At the same time, the inner diameter of the protective cover 12 is larger than the diameter of the silicone pad 01 that is compressed after being impacted, thereby avoiding the protective cover 12 restricting the stretching process of the silicone pad 01 that is compressed, thereby ensuring the accuracy of the test results.
[0057] Of course, the horizontal limiting structure of the silicone pad 01 is not limited to the above-mentioned protective cover 12, but can also be a plurality of arc-shaped limiting plates provided on the outer periphery of the silicone pad fixing seat 13.
[0058] Taking into account the large depth of the protective cover 12, in order to facilitate the removal and placement of the silicone pad 01, the protective cover 12 can be provided with at least one opening arranged along the axial direction, and the length of the opening is greater than the height of a layer of silicone pad 01; the shape of the opening is not limited, and is preferably a U-shaped opening with a regular shape and easy processing.
[0059] The above opening not only facilitates the taking and placing of the silicone pad 01 , but also makes it convenient for the operator to observe whether the silicone pad 01 , especially the lower silicone pad, is broken during the test.
[0060] On the basis of the above embodiment, the distance measuring device includes a high-precision ruler 10 provided on the side of the test frame, and the high-precision ruler 10 is provided perpendicular to the bottom plate 1 of the test frame.
[0061] During the test, first install the control handle 7 in the handle mounting seat, and under the pressure of the standard weight 8, make the treatment head at the bottom of the control handle 7 abut against the inner bottom surface of the silicone pad fixing seat 13 without the silicone pad 01. Use the high-precision ruler 10 to read the reading l0 corresponding to the upper edge of the standard weight 8 at this time;
[0062] Then, a layer of silicone pad 01 is placed in the silicone pad fixing seat 13, and a high-precision ruler 10 is used to read the reading l1 corresponding to the upper edge of the standard weight 8 at this time, and the distance d1=l0-l1 from the treatment head to the piezoelectric sensor 14 under a simulated load is calculated;
[0063] Then, the control handle 7 is pulled to release a single shock wave at the maximum output energy. The shock wave impacts the silicone pad 01, and the piezoelectric sensor 14 records the pressure value F1 attenuated after passing through the silicone pad 01.
[0064] Then, two layers of silicone pads 01 are placed in the silicone pad fixing seat 13. The reading l2 corresponding to the upper edge of the standard weight 8 is read with a high-precision ruler 10. The distance d1=l0-l2 from the treatment head to the piezoelectric sensor 14 under the two simulated loads is calculated.
[0065] Then, the control handle 7 is pulled to release a single shock wave at the maximum output energy. The emitted shock wave impacts the silicone pad 01. The piezoelectric sensor 14 is used to record the pressure value F2 that decays after passing through the two silicone pads 01. The penetration depth of the treatment head d=d1 / 2+F1*(d2-d1) / [2*(F1-F2)].
[0066] In this embodiment, the high-precision ruler 10 is vertically arranged on the base plate 1 of the test frame. Compared with the prior art of using a ruler to measure height, it ensures that the ruler body is parallel to the vertical direction during measurement, and the handle mounting base can limit the axis of the control handle 7 to be set along the vertical direction. Not only is the reading process simpler and the reading efficiency high, it also avoids the ruler body deviating from the axis of the control handle 7 during reading, thereby ensuring the accuracy of height detection.
[0067] In addition, compared with electronic components such as distance measuring sensors, the high-precision ruler 10 has a lower cost, which is conducive to reducing the cost of penetration depth measurement.
[0068] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0069] The above is a detailed introduction to the extracorporeal shock wave therapy device penetration depth measurement device provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above examples is only intended to help understand the method and core concept of the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, various improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
