Description

Technical Field

[0001] This invention relates to the field of testing instrument technology, and more specifically, to a tooling and testing equipment for testing surgical stand references. Background Technology

[0002] During treatment, surgical frames can assist doctors in injecting medications or drawing tissue fluid samples. Surgical head frames are a type of surgical frame, typically used in head treatment scenarios. A surgical head frame consists of a base ring and an adjustment frame. The adjustment frame houses an injection holder for mounting syringes. The adjustment frame is mounted on the base ring and allows for adjustment of the injection holder and syringe relative to the base ring in the XYZ directions. Both the base ring and the adjustment frame have corresponding baselines and scale lines. Before injection treatment, the adjustment frame and injection holder need to be positioned at their respective baselines (also known as the initial baseline position). During injection treatment, the base ring is fixed, and the doctor needs to move the injection holder and syringe according to the treatment plan, visually understanding the distance the syringe has moved in the XYZ directions using the scale lines to ensure movement accuracy and thus improve injection precision during treatment. The top of the base ring has multiple positioning holes spaced apart for installation and factory testing to mate with corresponding connection structures.

[0003] However, surgical head frames are prone to errors during production due to factors such as wear and tear on processing equipment. To ensure the accuracy of the syringe movement on the surgical head frame, the surgical head frame needs to be tested against the reference values ​​in the XYZ directions using a testing fixture before leaving the factory. The test checks whether the error values ​​are within the specified error range. Since the graduations on the surgical head frame are in millimeters, the industry standard is usually set at within one millimeter. The existing testing fixture includes a base and a standard testing needle. The base has a hemispherical testing groove at its center, and the end of the standard testing needle has a testing head that can be inserted into the testing groove. During testing, the syringe frame and adjustment frame are first adjusted to the initial reference position; then, the standard testing needle is positioned and inserted into the syringe frame, and then the testing head is visually inspected to see if it can be inserted into the testing groove. If it can be inserted, it is within the allowable error range. However, the above-mentioned detection method can only detect whether the initial position of the surgical head frame is within the allowable error range, and cannot intuitively know the actual error value in the XYZ directions, resulting in low detection accuracy. Moreover, as the surgical head frame wears down over a long period of use, the error value will also increase, and the doctor will not be able to know the actual error value, which will affect the adjustment accuracy and injection accuracy during treatment. Summary of the Invention

[0004] To address at least one of the aforementioned problems, the present invention first provides a fixture for detecting a surgical frame reference, comprising a base plate assembly, an X-axis detection component, a Y-axis detection component, and a standard needle for detecting Z-axis error. The base plate assembly is adapted to be positioned and mounted on a base ring; the standard needle is adapted to be slidably connected to an injection frame along the Z-axis, the bottom end of the standard needle having a detection ball head, and the standard needle having a Z-axis secondary scale line; the Y-axis detection component includes a Y-axis slider, the Y-axis slider sliding along the Y-axis on the base plate assembly, the base plate assembly having a Y-axis main scale line for measuring the movement distance of the Y-axis slider; the X-axis detection component includes an X-axis slider, The X-axis slider slides along the X-axis onto the Y-axis slider, and the X-axis slider and the Y-axis slider slide synchronously relative to the substrate assembly. The Y-axis slider is provided with an X-axis main scale line for measuring the movement distance of the X-axis slider, and the top of the X-axis slider is provided with a detection groove adapted to the detection ball head. When the injection holder and the standard needle are located at the initial reference position of the surgical head frame, the detection ball head is adapted to be inserted into the detection groove. The detection ball head is adapted to drive the X-axis slider and / or the Y-axis slider to automatically move a corresponding distance under the action of the error size, and the X-axis slider drives the standard needle to automatically rise a corresponding distance.

[0005] Optionally, the X-axis detection component further includes an X-axis subscale, which is connected to and moves synchronously with the X-axis slider. The X-axis subscale is provided with an X-axis subscale line corresponding to the X-axis main scale line. The X-axis main scale line is a millimeter scale line, and the X-axis subscale line is a micrometer scale line or a micrometer scale line.

[0006] Optionally, the Y-axis detection component further includes a Y-axis subscale, which is connected to and moves synchronously with the Y-axis slider. The Y-axis subscale is provided with a Y-axis subscale line corresponding to the Y-axis main scale line. The Y-axis main scale line is a millimeter scale line, and the Y-axis subscale line is a micrometer scale line or a micrometer scale line.

[0007] Optionally, a fixing sleeve is fitted onto the standard needle, and the fixing sleeve is detachably positioned and fixedly connected to the injection frame. The standard needle is provided with a stop ring, which abuts against the top of the fixing sleeve to limit the downward movement of the standard needle. The detection ball head is located below the fixing sleeve. The Z-axis ranging device is provided with a Z-axis secondary scale line, and the fixing sleeve is provided with a Z-axis main scale line that cooperates with the Z-axis secondary scale line. The Z-axis main scale line is a millimeter scale line, and the Z-axis secondary scale line is a micrometer scale line or a micrometer scale line.

[0008] Optionally, the X-axis slider is provided with a first set bolt, which is adapted to lock or unlock the movement of the X-axis slider; the Y-axis slider is provided with a second set bolt, which is adapted to lock or unlock the movement of the Y-axis slider.

[0009] Optionally, the X-scale is connected to the X-axis slider by bolts, and the X-scale has a first oblong hole for bolt insertion, the length direction of the first oblong hole being consistent with the moving direction of the X-axis slider.

[0010] Optionally, the Y-scale is connected to the Y-axis slider by bolts, and the Y-scale has a second oblong hole for bolt insertion, the length direction of the second oblong hole being consistent with the moving direction of the Y-axis slider.

[0011] Optionally, the substrate assembly includes a first plate, a second plate, and a lifting drive. The first plate has a positioning structure that is positioned and connected to the base ring. The second plate is located on top of the first plate. Both the first plate and the second plate are connected to the lifting drive. The lifting drive is adapted to drive the second plate to move up and down relative to the first plate. The X-axis detection component and the Y-axis detection component are both installed on top of the second plate and move up and down synchronously with the second plate. A scale is provided on the first plate or the second plate for measuring the lifting height of the second plate.

[0012] Optionally, the lifting drive component is a lead screw, which is rotatably connected to the second plate, and the top of the lifting drive component is exposed to the air for operation. The lifting drive component is threadedly connected to the first plate. A guide optical shaft is installed on the second plate, and a guide sleeve for the guide optical shaft to slide and insert is fixed on the first plate.

[0013] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0014] 1. When detecting the error of the surgical head frame reference value, the adjustment frame in the X, Y, and Z directions of the surgical head frame is located at the reference initial position, and the injection frame is also located at the reference initial position of the adjustment frame. At the same time, the X-axis slider and the Y-axis slider are both located at the reference position. After the standard needle is installed, the detection ball head will automatically insert into the detection groove. The error value in the X and Y directions of the surgical head frame will drive the X-axis slider and the Y-axis slider to move automatically and adaptively. The X-axis slider will drive the standard needle to move upward under the action of the Z-direction error value. The whole process does not require manual adjustment. The staff only needs to directly read the values ​​of the measuring devices in each direction to know the error value in each direction and mark it. At the same time, the surgical head frame can also be tested with tooling after a period of use, which helps doctors to eliminate error values, improve movement accuracy and drug injection accuracy, and thus improve treatment effect.

[0015] 2. The X, Y, and Z-axis subscales are in units smaller than millimeters, allowing for readings accurate to one or two decimal places. This provides higher precision in reading error values. Furthermore, during assembly, the X and Y subscales can be fine-tuned using the oblong holes, improving the accuracy of their reference values ​​in the X and Y directions and further enhancing the precision of error value readings so that users can be informed.

[0016] 3. The positioning structure and base ring are made of high precision and are connected with high accuracy. The positioning structure and base ring are connected with high accuracy, which can accurately transfer the scale lines on the base ring to the tooling and improve the accuracy of the test.

[0017] 4. If the user questions the accuracy of the test, the user can provide an XYZ coordinate. Then, the standard needle is adjusted to the corresponding position through the adjustment frame and injection frame. Then, the lifting drive is rotated to adjust the distance of the second plate to the corresponding Z direction. The distance of the X and Y direction sliders is used for verification. In addition, the Z direction position of the second plate can be adjusted according to the standard needles of different lengths. The applicability is relatively wide.

[0018] 5. The lifting drive uses a lead screw. After the lead screw is threadedly connected to the first plate, a threaded locking structure is formed. When the second plate is subjected to vertical force, it is not easy for it to move relative to the first plate. Only by rotating the lead screw can the second plate be driven to move, which improves the stability of the second plate after adjustment and thus improves the accuracy of detection.

[0019] In addition, the present invention provides a testing device, including the tooling described above for testing a surgical stand reference.

[0020] Compared with the prior art, the detection device described in this invention and the tooling for detecting surgical frame reference described above have the same advantages over the prior art, and will not be repeated here. Attached Figure Description

Detailed Implementation

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the following description is provided. Figures 1-11 This application will be described in further detail.

[0034] The accompanying drawings of this embodiment of the invention provide a coordinate system XYZ, where the positive direction of the X-axis represents the right, the negative direction of the X-axis represents the left, the positive direction of the Y-axis represents the front, the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom.

[0035] Reference Figure 1 The surgical head frame includes a base ring 5 and an adjustment frame 6. An injection holder 7 for mounting a syringe is installed on the adjustment frame 6. The adjustment frame 6 is mounted on the base ring 5 and can adjust the injection holder 7 and syringe relative to the base ring 5 in the XYZ directions. Both the base ring 5 and the adjustment frame 6 have corresponding baselines and scale lines. Before injection treatment, the adjustment frame 6 and injection holder 7 need to be positioned at their respective baselines (also known as the initial baseline positions). During injection treatment, the base ring 5 is fixed, and the doctor needs to move the injection holder 7 and syringe according to the treatment plan, visually understanding the distance the syringe moves in the XYZ directions using the scale lines to ensure movement accuracy and thus improve injection accuracy during treatment. The top of the base ring 5 has multiple positioning holes 8 spaced apart for installation and factory testing to mate with corresponding connection structures.

[0036] In a first aspect, embodiments of the present invention provide a fixture for detecting a surgical stand reference, with reference to... Figures 1 to 4The fixture for detecting the reference of the surgical frame includes a base plate assembly 1, an X-axis detection component 2, a Y-axis detection component 3, and a standard needle 4 for detecting Z-axis error. The base plate assembly 1 and the base ring 5 are positioned and connected; the standard needle 4 is adapted to slide along the Z-axis to the injection frame 7; the X-axis detection component 2 slides along the X-axis on top of the Y-axis detection component 3, and the Y-axis detection component 3 slides along the Y-axis on top of the base plate assembly 1, with the X-axis detection component 2 and Y-axis detection component 3 moving synchronously. The base plate assembly 1 is provided with a Y-axis measuring element for measuring the moving distance of the Y-axis detection component 3; the Y-axis detection component 3 is provided with an X-axis measuring element for measuring the moving distance of the X-axis detection component 2; the standard needle 4 is provided with a Z-axis measuring element for measuring the moving distance of the standard needle 4. The standard needle 4 is located above the X-axis detection component 2, and a detection ball head 41 is integrally formed at the bottom end of the standard needle 4. The top of the X-axis detection component 2 is provided with a hemispherical detection groove 42 that is adapted to and allows the detection ball head 41 to be inserted. When the injection holder 7 and the standard needle 4 are in the initial position of the surgical head frame reference, the detection ball head 41 is adapted to be inserted into the detection groove 42. The detection ball head 41 is adapted to drive the X-axis detection component 2, the Y-axis detection component 3 and the standard needle 4 to move automatically by the corresponding distance under the action of the error size, so that the user can read and mark the error values ​​in the three directions of X, Y and Z. This helps doctors to eliminate error values, improve the accuracy of movement and drug injection, and thus improve the treatment effect.

[0037] The X-axis detection component 2 moves in the X-axis direction of the coordinate system; the Y-axis detection component 3 moves in the Y-axis direction of the coordinate system; and the standard needle 4 moves in the Z-axis direction of the coordinate system.

[0038] Reference Figures 2 to 5The substrate assembly 1 includes a base 11, a first plate 12, a second plate 13, and a lifting drive component 14, all manufactured using high-precision instruments. During testing, the base ring 5 of the surgical frame is positioned on top of the base 11. The base 11, manufactured using high-precision instruments, ensures a high degree of flatness on its top surface, resulting in a relatively flat surface for the surgical frame and thus higher testing accuracy. Furthermore, the base 11 supports the base ring 5, preventing the Z-axis movement of the adjustment frame 6 within the surgical frame from contacting the table surface and affecting the accuracy of the measurement data. The bottom of the first plate 12 has an integrally formed positioning structure that connects to the base ring 5. This positioning structure consists of positioning pins 121, which are the same number of positioning holes 8 on the base ring 5 and correspond one-to-one. The positioning pin 121 and the positioning hole 8 have high precision, which enables the accurate transfer of the scale lines in the XY direction on the surgical head frame to the Y-direction detection component 3 and the first plate 12. This ensures the accuracy and precision of the error values ​​obtained from reading the values ​​of the X-direction and Y-direction distance measuring devices. The second plate 13 is located on top of the first plate 12. Both the first plate 12 and the second plate 13 are connected to the lifting drive component 14. The lifting drive component 14 is adapted to drive the second plate 13 to rise and fall relative to the first plate 12. The X-direction detection component 2 and the Y-direction detection component 3 are both installed on top of the second plate 13 and rise and fall synchronously with the second plate 13.

[0039] If the user has doubts about the detection accuracy, the user can provide an XYZ coordinate, and then the standard needle 4 can be adjusted to the corresponding position through the adjustment frame 6 and the injection frame 7. Then, the lifting drive component 14 can be rotated to adjust the second plate 13 to the corresponding Z-axis distance, and the verification can be carried out in combination with the distance moved by the X-axis detection component 2 and the Y-axis detection component 3. In addition, the Z-axis position of the second plate 13 can also be adjusted according to the standard needle 4 of different lengths.

[0040] Reference Figures 4 to 6 A millimeter-scale ruler 122 is bolted to one side of the top of the first plate 12. A notch is formed on the side of the second plate 13, through which the ruler 122 is inserted. A micrometer-scale line is provided on the side of the second plate 13 with the notch, corresponding to the ruler 122. This allows the reading of the lifting height of the second plate 13. Simultaneously, the interaction between the ruler 122 and the scale line during reading resembles the structure of a vernier caliper, providing a numerical accuracy to 0.1 millimeters. In another embodiment, the scale line corresponding to the ruler 122 on the second plate 13 can also be a micrometer scale line, achieving a numerical accuracy to 0.01 millimeters.

[0041] Reference Figures 5 to 8The first plate 12 has a lower groove at the top center, and a first sleeve 123 is integrally formed at the center of the bottom of the lower groove. The second plate 13 has a second sleeve 131 integrally formed at the bottom. The second sleeve 131 slides vertically into the first sleeve 123. The first sleeve 123 and the second sleeve 131 have a high fitting precision. When the second plate 13 moves up and down relative to the first plate 12, it can play a precise guiding role to improve the accuracy of the second plate 13 when moving up and down.

[0042] The first sleeve 123 has an end plate integrally formed at its bottom, making it an open-top sleeve. A threaded sleeve 124 is integrally formed at the center of the end plate. In this embodiment, the lifting drive 14 is preferably a lead screw, which is rotatably connected to the second plate 13. The top of the lifting drive 14 is exposed to the air for the operator to use tools to rotate the lead screw. The lead screw is inserted into the threaded sleeve 124 and threadedly connected to the first plate 12. Therefore, rotating the lead screw can drive the second plate 13 to move relative to the first plate 12. After the lead screw stops rotating, the second plate 13 forms a threaded lock under the action of the threaded engagement between the lead screw and the threaded sleeve 124, stopping its movement and improving the stability of the second plate 13 after adjustment. In another embodiment, the lifting drive 14 is an electric cylinder, with the cylinder body fixedly connected to the first plate 12 by bolts, and the telescopic rod of the electric cylinder fixedly connected to the second plate 13. In yet another embodiment, the lifting drive 14 is a lead screw motor.

[0043] Reference Figures 5 to 7 The second plate 13 has a bearing hole at its bottom, located inside the second sleeve 131 and concentrically aligned with it. The bearing hole extends through the second plate 13, and a rotating bearing is installed within it. The lead screw is rotatably inserted into the rotating bearing. End caps are provided at both ends of the bearing, and these caps are fixedly connected to the second plate 13 with bolts, preventing the rotating bearing from shifting vertically. A support ring plate 141 is integrally formed on the lead screw. The outer diameter of the support ring plate 141 is larger than the inner diameter of the rotating bearing, thus providing support for the second plate 13 and preventing relative movement between the lead screw and the second plate 13 in the vertical direction.

[0044] The second plate 13 has a positioning mounting hole at its bottom, into which a guide optical shaft 132 is inserted, precisely fitting with the positioning mounting hole. A connecting ring plate is integrally formed on the guide optical shaft 132, and the connecting ring plate is fixedly connected to the second plate 13 by bolts. A guide sleeve 125 is integrally formed in the lower groove, and the guide optical shaft 132 is slidably inserted into the guide sleeve 125, with the guide sleeve 125 precisely fitting with the guide optical shaft 132. This serves two purposes: firstly, it provides guidance; secondly, it prevents the second plate 13 from rotating synchronously with the lead screw. Multiple mounting holes, guide optical shafts 132, and guide sleeves 125 are provided, thereby improving the precision of the fit between the second plate 13 and the first plate 12.

[0045] Combination Figure 4 Reference Figure 5 and Figure 9 The Y-axis detection component 3 includes a Y-axis slider 31, a Y-axis scale 32, a Y-axis linear guide, and a Y-axis guide slider. The Y-axis linear guide is bolted to the top of the second plate 13; the Y-axis guide slider slides along the Y-axis on the Y-axis linear guide. Two Y-axis linear guides and two Y-axis guide sliders are spaced apart along the X-axis, with each Y-axis linear guide corresponding to one Y-axis guide slider. The Y-axis slider 31 is bolted to the two Y-axis guide sliders, thus improving the accuracy and stability of the Y-axis slider 31 during movement. A Y-axis distance measuring element is located on the top of the second plate 13, to the left of the Y-axis slider 31, and is used to read the distance the Y-axis slider 31 moves. Since the Y-axis distance measuring element is located to the left of the Y-axis slider 31, the Y-axis scale 32 is also installed to the left of the Y-axis slider 31 and moves synchronously with it. The Y-axis scale 32 can cooperate with the Y-axis distance measuring element to improve the accuracy of the read values.

[0046] In this embodiment, the Y-axis distance measuring device preferably has a Y-axis main scale line 33, which is a millimeter scale line with size numerical markings. The Y-axis auxiliary scale 32 has a Y-axis auxiliary scale line 34 corresponding to the Y-axis main scale line 33. The Y-axis auxiliary scale line 34 is a micrometer scale line, where one millimeter equals ten micrometers. In another embodiment, the Y-axis auxiliary scale line 34 is a micrometer scale line, where one micrometer equals ten micrometers. When reading the value, the value corresponding to the 0 mark on the Y-axis auxiliary scale line 34 and the Y-axis main scale line 33 is first read to obtain the millimeter accuracy. Then, the value at the point on the Y-axis auxiliary scale line 34 that aligns with the corresponding scale line of the Y-axis main scale line 33 is converted to obtain the micrometer accuracy value, thereby improving the accuracy of the value reading. In another embodiment, the Y-axis distance measuring device can be a laser rangefinder, thus directly reading the value. In yet another embodiment, the Y-axis distance measuring device can be a high-precision electronic measuring instrument such as an inductive displacement sensor, thus directly reading the value.

[0047] Combination Figure 4 Reference Figure 5and Figure 9 The left end of the Y-axis slider 31 has a first mounting groove. The Y-axis auxiliary ruler 32 is bolted into the first mounting groove, making the connection between the Y-axis slider 31 and the Y-axis auxiliary ruler 32 more compact and reducing the volume occupied. The Y-axis auxiliary ruler 32 has a second oblong hole for bolt insertion. The length direction of the second oblong hole is consistent with the movement direction of the Y-axis slider 31; and the second oblong hole is a countersunk hole, reducing the protruding length of the bolt head fixing the Y-axis auxiliary ruler 32. When assembling or adjusting the accuracy of the Y-axis auxiliary ruler 32 in conjunction with the Y-axis main scale line 33, the Y-axis auxiliary ruler 32 can be finely adjusted by the bolt and the second oblong hole, thereby ensuring the fitting accuracy and improving the reading accuracy. Furthermore, the Y-mounted scale 32 is spaced apart from the corresponding first mounting groove walls in both Y directions. Each of the two groove walls corresponding to the first mounting groove in the Y direction has threaded holes penetrating the Y-axis slider 31. A Y-axis adjusting bolt 35 is threaded into each threaded hole, and two Y-axis adjusting bolts 35 are respectively inserted into the first mounting groove and abut against the Y-axis sides of the Y-mounted scale 32. For fine-tuning the Y-mounted scale 32, the bolt in the second oblong hole can be loosened, and then the two Y-axis adjusting bolts 35 can be rotated for adjustment. The Y-axis adjusting bolts 35 can drive the Y-mounted scale 32 to move a small distance for fine-tuning, improving adjustment accuracy. In addition, the threaded locking structure of the two Y-axis adjusting bolts 35 on the Y-mounted scale 32 makes it less likely for the Y-mounted scale 32 to move along the Y direction under the action of the second oblong hole, improving the stability of the Y-mounted scale 32 after fixation.

[0048] The side of the Y-scale 32 closest to the Y-direction main scale line 33 is inclined, and the Y-direction secondary scale line 34 is located on the inclined surface. When reading the value, the operator does not need to squat down to keep their line of sight level with the side plate of the Y-direction slider 31, but can simply look down to see the Y-direction main scale line 33 and the Y-direction secondary scale line 34, which improves the operator's comfort when reading the value.

[0049] Combination Figure 4 Reference Figure 5 and Figure 9 A second set bolt 36 is threaded onto the top of the Y-axis slider 31. The second set bolt 36 passes through the Y-axis slider 31. By rotating the second set bolt 36, it can be pressed against the top surface of the second plate 13, thereby locking the Y-axis slider 31 and preventing it from moving. This prevents accidental movement of the Y-axis slider 31 during value reading, which could affect the accuracy of the value. After the value reading is completed, loosening the second set bolt 36 unlocks the movement of the Y-axis slider 31, allowing it to move again.

[0050] Combination Figure 4 Reference Figures 8 to 11The X-axis detection component 2 includes an X-axis slider 21, an X-axis scale 22, an X-axis linear guide rail, and an X-axis guide rail slider. The X-axis linear guide rail is bolted to the top of the Y-axis slider 31. The X-axis guide rail slider slides along the X-axis linear guide rail. The X-axis slider 21 is bolted to the X-axis guide rail slider to achieve synchronous movement, and the X-axis slider 21 and the Y-axis slider 31 slide synchronously relative to the second plate 13. The Y-axis length of the X-axis slider 21 is less than the Y-axis length of the Y-axis slider 31, and the rear side of the X-axis slider 21 is spaced from the rear side of the Y-axis slider 31, thus leaving space for the X-axis distance measuring device. Therefore, the X-axis distance measuring device is located on the top of the Y-axis slider 31 and behind the X-axis slider 21, and is used to read the movement distance of the X-axis slider 21. Since the X-axis rangefinder is located behind the X-axis slider 21, the X-axis auxiliary ruler 22 is also installed behind the X-axis slider 21 and moves synchronously with it. The X-axis auxiliary ruler 22 can cooperate with the X-axis rangefinder to improve the accuracy of the read values. When the detection ball head 41 is inserted into the detection groove 42, if there is an error, the X-axis slider 21 and the Y-axis slider 31 will move automatically with the cooperation of the detection ball head 41 and the detection groove 42.

[0051] In this embodiment, the X-axis ranging device preferably has an X-axis main scale line 23, which is a millimeter scale line with size numerical markings. The X-axis auxiliary scale 22 has an X-axis secondary scale line 24 corresponding to the X-axis main scale line 23. The X-axis secondary scale line 24 is a micrometer scale line, where one millimeter equals ten micrometers. In another embodiment, the X-axis secondary scale line 24 is a micrometer scale line, where one micrometer equals ten micrometers. The method for reading the values ​​is the same as that for the Y-axis detection component 3, and will not be repeated here, thereby improving the accuracy of the X-axis value reading. In another embodiment, the X-axis ranging device can be a laser rangefinder, thereby directly reading the values; in yet another embodiment, the X-axis ranging device can be a high-precision electronic measuring instrument such as an inductive displacement sensor, thereby directly reading the values.

[0052] Reference Figure 10 and Figure 11A second mounting groove is provided on the rear side of the X-axis slider 21. The X-axis auxiliary ruler 22 is installed in the second mounting groove by bolts, making the connection between the X-axis slider 21 and the X-axis auxiliary ruler 22 more compact and reducing the volume occupied. The X-axis auxiliary ruler 22 has a first oblong hole for bolt insertion. The length direction of the first oblong hole is consistent with the movement direction of the X-axis slider 21; and the first oblong hole is a countersunk hole, reducing the length of the bolt head protruding when fixing the X-axis auxiliary ruler 22. When assembling or adjusting the accuracy of the fit between the X-axis auxiliary ruler 22 and the X-axis main scale line 23, the X-axis auxiliary ruler 22 can be finely adjusted by the cooperation of the bolt and the first oblong hole, thereby ensuring the fit accuracy and improving the reading accuracy. Furthermore, the X-scale 22 is spaced apart from the corresponding second mounting groove walls in both X directions. Each of the two groove walls corresponding to the second mounting groove in the X direction has threaded holes penetrating the X-axis slider 21. Each threaded hole contains a threaded X-axis adjusting bolt 25, which is inserted into the second mounting groove and abuts against both sides of the X-scale 22 in the X direction. For fine-tuning the X-scale 22, the bolt in the first oblong hole can be loosened, and then the two X-axis adjusting bolts 25 can be rotated for adjustment. The X-axis adjusting bolts 25 can drive the X-scale 22 to move a small distance for fine-tuning, improving adjustment accuracy. In addition, the threaded locking structure of the two X-axis adjusting bolts 25 on the X-scale 22 makes it less likely for the X-scale 22 to move along the X direction under the action of the first oblong hole, improving the stability of the X-scale 22 after fixation.

[0053] The side of the X-axis secondary scale 22 closest to the X-axis main scale line 23 is also designed as an inclined surface, and the X-axis secondary scale line 24 is located on the inclined surface. When reading the value, the operator does not need to squat down to keep their line of sight level with the side plate of the X-axis slider 21, but can simply look down to see the X-axis main scale line 23 and the X-axis secondary scale line 24, which improves the operator's comfort when reading the value.

[0054] Reference Figure 10 and Figure 11 A first set bolt 26 is threaded onto the top of the X-axis slider 21. The first set bolt 26 passes through the X-axis slider 21. By rotating the first set bolt 26, it can be pressed against the top surface of the Y-axis slider 31, thereby locking the X-axis slider 21 and preventing it from moving. This prevents accidental movement of the X-axis slider 21 during value reading, which could affect the accuracy of the reading. After the value reading is completed, loosening the first set bolt 26 unlocks the X-axis slider 21, allowing it to move again.

[0055] Both the X-axis and Y-axis linear guides are threaded with stop screws to prevent the X-axis and Y-axis sliders from falling off the linear guides.

[0056] Reference Figure 2 and Figure 3 A fixed sleeve 43 is fitted onto the standard needle 4. The fixed sleeve 43, like the standard needle 4, is a dedicated testing component with high dimensional accuracy. The fixed sleeve 43 is detachably and positionably mounted on the injection holder 7 and fits precisely with it. The standard needle 4 is inserted into the fixed sleeve 43, and the testing ball head 41 passes through the fixed sleeve 43 and is located below it. The standard needle 4 can move relative to the fixed sleeve 43. An integrally formed stop ring 44 is formed on the standard needle 4. The outer diameter of the stop ring 44 is larger than the inner diameter of the fixed sleeve 43. The stop ring 44 is located at the top of the fixed sleeve 43 and abuts against its top surface to limit the downward movement of the standard needle 4, ensuring the correct height of the testing ball head 41 during each measurement.

[0057] Reference Figures 2 to 4 The outer wall of the fixed sleeve 43 has an opening groove, and the groove wall has a Z-axis main scale line 45 for measuring the movement distance of the standard needle 4. The Z-axis ranging element is a Z-axis secondary scale line 46 that cooperates with the Z-axis main scale line 45. The Z-axis main scale line 45 is a millimeter scale line, and the Z-axis secondary scale line 46 is a micrometer scale line, where one millimeter equals ten micrometers. In another embodiment, the Z-axis secondary scale line 46 is a micrometer scale line, where one micrometer equals ten micrometers. The method of reading the value is the same as the reading method of the Y-axis detection component 3, and will not be repeated here, thereby improving the accuracy of the Z-axis value reading.

[0058] In another embodiment, a laser rangefinder for detecting the moving distance of the standard needle 4 can be installed on the fixed sleeve 43, and the value can be read directly; in yet another embodiment, a high-precision electronic measuring instrument such as an inductive displacement sensor for detecting the moving distance of the standard needle 4 can be installed on the fixed sleeve 43, and the value can be read directly.

[0059] In this case, the baseline of the Z-axis main scale line 45 is located in the middle position. When the stop ring 44 abuts against the top surface of the fixed sleeve 43, the baseline of the Z-axis secondary scale line 46 is located below the baseline of the Z-axis main scale line 45. Therefore, during measurement, the standard needle 4 will rise. By detecting whether the baseline of the Z-axis secondary scale line 46 is above or below the baseline of the Z-axis main scale line 45 after the standard needle 4 rises, the value can be read to obtain the positive or negative error value in the Z-axis direction.

[0060] The implementation principle of a tooling for detecting the reference value of a surgical head frame according to an embodiment of this application is as follows: Before detecting the error of the reference value of the surgical head frame, the adjustment frame 6 in the XYZ directions of the surgical head frame is first positioned at the reference initial position, and the injection frame 7 is moved to the reference initial position of the adjustment frame 6. Then, the base ring 5 is placed on the base 11, and then the first plate 12 is placed on the base ring 5 and the positioning pin 121 is positioned and inserted into the positioning hole 8, so that the dimensions in the XY directions are accurately converted to the Y-direction detection component 3 and the first plate 12. In addition, the X-direction slider 21 and the Y-direction slider 31 are both moved to the reference position. Then, the standard needle 4 is inserted into the fixing sleeve 43, and the detection ball head 41 is automatically inserted into the detection groove 42. Error values ​​in the X and Y directions of the surgical head frame will cause the X-axis slider 21 and Y-axis slider 31 to move adaptively and automatically. The X-axis slider 21 will move the standard needle 4 upwards under the influence of the Z-axis error value. The entire process requires no manual adjustment; staff only need to directly read the values ​​from the measuring devices in each direction to determine and mark the error values. Even after the surgical head frame has worn down over a period of use, the error values ​​can still be detected using the above operation.

[0061] Among them, the X-scale 22, Y-scale 32, and Z-axis secondary scale line 46 are scales with units smaller than millimeters, allowing for reading values ​​accurate to one or two decimal places, resulting in higher precision in reading error values. Furthermore, when assembling or adjusting the precision value of the Y-scale 32 in conjunction with the Y-axis main scale line 33, the Y-scale 32 can be fine-tuned using the bolt and the second oblong hole, thus ensuring fitting accuracy and improving reading precision; similarly, the X-scale 22 can also be adjusted in this way.

[0062] Secondly, another embodiment of the present invention provides a testing device, including the tooling described in the first aspect for testing a surgical frame reference.
