Description

Technical Field

[0001] This invention relates to the field of equipment structure testing technology, specifically to a device and method for testing handle rotation parameters and window displacement. Background Technology

[0002] Biopsy and excision devices are commonly used in medical devices for minimally invasive biopsies of lesions and the removal of benign tumors. The structure used to remove the lesion is a handle containing an inner and outer needle. The frequency of the inner needle's rotation, the rotation angle of the outer needle, and the size of the inner needle's fenestration all directly affect the final resection outcome. Therefore, it is necessary to test the frequency of the inner needle's rotation, the rotation angle of the outer needle, and the size of the inner needle's fenestration to facilitate the improvement and optimization of the device.

[0003] Existing handle testing equipment requires connecting the needle and sensor with a coupling when testing the outer needle rotation angle and inner needle cutting frequency. The sensor output signal needs to be connected to an oscilloscope. During testing, the sensor and needle must be kept coaxial before the oscilloscope is used to read the measurement curve and calculate the rotation angle and rotation time. On the one hand, fixing the handle is difficult, making it hard to maintain coaxiality between the sensor and needle. On the other hand, using an oscilloscope is cumbersome, requires highly skilled production personnel, and necessitates excessive manual intervention. Furthermore, calculating the angle and rotation time based on the oscilloscope readings manually is prone to errors and time-consuming.

[0004] Furthermore, the opening of the inner needle in the handle requires measurement with calipers, which introduces human error. Also, the inner needle has rounded corners, and applying slight force with the calipers can cause it to shift, resulting in measurement errors.

[0005] Therefore, with the increasing production volume, it is no longer possible to meet the existing testing requirements. Summary of the Invention

[0006] In order to solve the above-mentioned technical problems in the prior art, the present invention provides a device and method for testing handle rotation parameters and window opening displacement.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows:

[0008] In a first aspect, the present invention provides a device for testing handle rotation parameters and window opening displacement, comprising a test platform, wherein an inner needle rotation frequency testing component and an inner needle parameter testing carrier are disposed on the test platform, and the inner needle parameter testing carrier is used to clamp the handle to be tested; the inner needle rotation frequency testing component includes an angle sensor, a first gear and a second gear, wherein a first shaft is disposed in the test hole of the angle sensor, and the first gear is disposed on the first shaft; during testing, the second gear is mounted on the inner needle of the handle to be tested, and when the handle to be tested is clamped on the inner needle parameter testing carrier, the first gear meshes with the second gear.

[0009] Furthermore, a displacement sensor is also provided on the test bench, which is used to measure the axial displacement of the second gear.

[0010] Furthermore, the displacement sensor is a laser displacement sensor.

[0011] Furthermore, the inner needle parameter testing carrier includes a handle carrier and a clamping assembly. A groove is provided on the upper part of the handle carrier, the handle to be tested is placed in the groove, and the clamping assembly is used to clamp the handle to be tested.

[0012] Furthermore, the test bench is also equipped with an outer needle rotation angle test assembly and an outer needle parameter test carrier. The outer needle rotation angle test assembly includes an angle sensor, a positioning pin is provided in the test hole of the angle sensor, a material retainer is provided on the positioning pin, and a central hole is provided in the material retainer. During the test, the outer needle of the handle to be tested is inserted into the central hole.

[0013] Furthermore, the material retainer is made of a flexible material, specifically polyurethane.

[0014] Furthermore, the external needle parameter testing carrier includes a handle carrier and a clamping assembly. A groove is provided on the upper part of the handle carrier, the handle to be tested is placed in the groove, and the clamping assembly is used to clamp the handle to be tested.

[0015] Secondly, the present invention provides a method for testing the rotation parameters of a handle, used to test the frequency of inner needle rotation and cutting of the handle, comprising:

[0016] A1. Install the second gear onto the inner needle of the handle to be tested, and then fix the handle to be tested onto the inner needle parameter testing carrier.

[0017] A2. Connect the above-mentioned handle rotation parameters and window displacement testing device to the processing center, and connect the product host to the handle to be tested.

[0018] A3. Conduct testing to obtain the angle data and corresponding timestamps from the angle sensor of the inner needle rotation frequency testing component. Calculate the number of inner needle rotations based on the angle data and the inner needle rotation time based on the timestamps.

[0019] A4. The frequency of inner needle rotation and cutting is calculated based on the number of inner needle rotations and the inner needle rotation time.

[0020] Furthermore, in step A3, the number of inner needle rotation cuts is calculated based on the angle data. The specific method is as follows:

[0021] Set the initial value of A to zero and the initial value of B to zero. Record the angle data in chronological order. If the difference between the current angle data and the previous angle data is greater than 1, then increment the value of A by 1; if the difference between the current angle data and the previous angle data is less than 1, then increment the value of B by 1.

[0022] The number of times the inner needle is rotated and cut is:

[0023]

[0024] C represents the number of times the inner needle is rotated and cut.

[0025] Furthermore, in step A3, the inner needle cutting time is calculated based on the timestamp. The specific method is as follows:

[0026] Record the angle data in chronological order, and subtract the time corresponding to the first angle data from the time corresponding to the last angle data to obtain the inner needle rotation cutting time.

[0027] Furthermore, the inner needle cutting frequency is calculated based on the number of inner needle cuttings and the inner needle cutting time. The specific method is as follows: inner needle cutting frequency = number of inner needle cuttings / inner needle cutting time.

[0028] Furthermore, after calculating the number of inner needle rotations in step A3, the process also includes determining whether the required number of rotations is met, specifically:

[0029] If the number of inner needle rotations is greater than 1, continue calculating the inner needle rotation time;

[0030] If the number of inner needle rotations is less than or equal to 1, it indicates that the number of rotations is insufficient and needs to be measured again.

[0031] Thirdly, the present invention provides a method for testing the rotation parameters of a handle, used to test the window length of the handle, comprising:

[0032] B1. Install the second gear onto the inner needle of the handle to be tested, and then fix the handle to be tested onto the inner needle parameter testing carrier.

[0033] B2. Connect the above-mentioned handle rotation parameters and window displacement testing device to the processing center, and connect the product host to the handle to be tested.

[0034] B3. Adjust the handle so that the tip of the inner needle of the handle coincides with the outer edge of the window;

[0035] B4. Conduct a test and use a displacement sensor to obtain the movement distance of the second gear, which is the opening length of the handle.

[0036] Fourthly, the present invention provides a method for testing the rotation parameters of a handle, used to test the rotation angle and rotation time of the outer pin of the handle, comprising:

[0037] C1. Fix the handle to be tested onto the external needle parameter testing carrier, and insert the external needle of the handle into the center hole of the material holder and press it against the positioning pin.

[0038] C2. Connect the above-mentioned handle rotation parameters and window displacement testing device to the processing center, and connect the product host to the handle to be tested.

[0039] C3. Obtain the initial angle value and the corresponding timestamp, denoted as initial angle value A1 and initial time value T1;

[0040] C4. Perform the test to obtain the angle data and the corresponding timestamp, which are recorded as angle value A2 and time value T2.

[0041] C5. Calculate the rotation angle and rotation time of the outer needle.

[0042] Furthermore, the specific method for obtaining the initial angle value in step C3 is as follows: obtain the last angle data among all angle data where the difference between the current angle value and the angle value at the previous moment is less than 0.1, and denote it as A1.

[0043] Furthermore, the specific method for obtaining the angle value A2 is as follows: During the test, the angle data is recorded in chronological order. When the difference between the current angle value and the angle value at the previous moment is greater than 1 for the first time, all angles D after the current angle value are obtained. In the angle data D, the angle data with the difference between the current angle data and the angle data at the previous moment being less than 0.1 for the first time is obtained in chronological order and recorded as the angle value A2.

[0044] Further, step C5 calculates the outer needle rotation angle and the outer needle rotation time, specifically including:

[0045] Calculate the absolute value of the difference between A2 and A1.

[0046] If |A2-A1|≤0.1, then the test needs to be repeated;

[0047] If |A2-A1|>0.1, then the rotation angle of the outer needle is |A2-A1|, and the rotation time of the outer needle is T2-T1.

[0048] Compared with the prior art, the present invention has the following beneficial effects:

[0049] This invention provides a device and method for testing handle rotation parameters and window opening displacement. A test platform is set up, on which a carrier is placed to fix the handle. A second gear is installed on the inner needle of the handle, and an angle sensor is installed on one side of the handle. A first gear is installed on the angle sensor, and the first gear meshes with the second gear. When the inner needle rotates, it drives the second gear to rotate, which in turn drives the first gear to rotate. The rotation of the inner needle can be measured by the angle sensor, and the inner needle cutting frequency can be calculated. This invention not only allows for rapid connection but also eliminates the need for manual calculation. By automatically acquiring the inner needle cutting frequency and the corresponding cutting time, it reduces testing complexity and improves testing accuracy.

[0050] In addition, the present invention also improves the testing accuracy by setting a displacement sensor on one side of the inner needle and measuring the movement distance of the second gear to obtain the handle window length, thus avoiding errors caused by manual measurement.

[0051] The present invention also includes an additional angle sensor with a material holder on it. The outer needle is inserted into the material holder, and the rotation of the outer needle can drive the material holder to rotate. The angle sensor can then measure the rotation angle of the outer needle and the rotation time of the outer needle, allowing for intuitive reading of the measurement results and facilitating operation by the operator.

[0058] The technical solution of the present invention will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are not all embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0059] It should be noted that, unless otherwise specifically stated, the relative arrangement and numerical expressions of the components and steps described in these embodiments should not be construed as limiting the scope of the invention.

[0060] The following description of exemplary embodiments is merely illustrative and is not intended to limit the invention or its application or use in any way. Techniques, methods, and apparatus known to those skilled in the art may not be discussed in detail herein, but where applicable, such techniques, methods, and apparatus should be considered part of this specification.

[0061] Example 1

[0062] This embodiment provides a device for testing handle rotation parameters and window opening displacement, such as... Figure 1 As shown, the device includes a test bench 1, on which an inner needle rotation frequency testing component and an inner needle parameter testing carrier 2 are mounted. The inner needle parameter testing carrier 2 is used to clamp the handle to be tested. The inner needle rotation frequency testing component includes an angle sensor 4, a first gear 5, and a second gear 6. A first shaft is disposed in the test hole of the angle sensor 4, and the first gear 5 is disposed on the first shaft. During testing, the second gear 6 is mounted on the inner needle of the handle to be tested. When the handle to be tested is clamped on the inner needle parameter testing carrier 2, the first gear 5 meshes with the second gear 6.

[0063] The second gear 6 is fixedly connected to the inner needle. Therefore, when the inner needle rotates, the second gear 6 rotates synchronously with the inner needle. Since the first gear 5 meshes with the second gear 6, the rotation of the inner needle can be obtained by acquiring the rotation of the first gear 5. The rotation of the first gear 5 is directly measured by the angle sensor 4, without the need for an oscilloscope, making the operation simple.

[0064] The second gear 6 is also equipped with ball bearings. Specifically, multiple holes, preferably six, are arranged radially on the connecting shaft of the second gear 6. Two holes are arranged axially at 120° intervals. Ball bearings are installed in the holes. The ball bearings are embedded in the holes but can roll. When the inner needle is inserted into the center hole of the second gear 6, the inner needle contacts the ball bearings, thereby changing the sliding friction between the inner needle and the second gear 6 into rolling friction, thus avoiding wear of the inner needle.

[0065] In addition, a displacement sensor 7 is also installed on the test bench 1. The displacement sensor 7 is used to measure the axial displacement of the second gear 6. The displacement sensor 7 is a laser displacement sensor. The position of the displacement sensor 7 is set according to the moving distance of the second gear 6, and it is necessary to ensure that the distance between the displacement sensor 7 and the second gear 6 is within the measurement range.

[0066] The inner needle parameter testing carrier 2 includes a handle carrier and a clamping assembly 3. A groove is provided on the top of the handle carrier, and the handle to be tested is placed in the groove. The clamping assembly 3 is used to clamp the handle to be tested. The handle carrier is preferably made of aluminum with an anodized surface, which provides corrosion resistance and prevents rusting. The clamping assembly 3 can use existing clamping structures; the specific structural principle will not be elaborated here.

[0067] The test bench 1 is also equipped with an outer needle rotation angle test assembly and an outer needle parameter test carrier 8. The outer needle rotation angle test assembly includes an angle sensor 4. A positioning pin is set in the test hole of the angle sensor 4. A material retainer 9 is set on the positioning pin. A center hole is set in the material retainer 9. During the test, the outer needle of the handle to be tested is inserted into the center hole.

[0068] The material retainer 9 is made of flexible material, preferably polyurethane. The flexible material material of the material retainer 9 avoids wear on the outer needle. The material retainer 9 and the outer needle are interference-fitted, without the need for other locking structures, which makes it easy to disassemble, suitable for mass production, and improves testing efficiency.

[0069] The external needle parameter testing carrier 8 includes a handle carrier and a clamping assembly 3. A groove is provided on the top of the handle carrier, and the handle to be tested is placed in the groove. The clamping assembly 3 is used to clamp the handle to be tested. The external needle parameter testing carrier 8 has the same structure as the internal needle parameter testing carrier 2.

[0070] Example 2

[0071] This embodiment provides a method for testing the rotation parameters of a handle, used to test the frequency of the inner needle rotation of the handle, such as... Figure 2 As shown, it includes:

[0072] A1. Install the second gear 6 onto the inner needle of the handle to be tested. The second gear 6 presses against the structural component on the handle. Fix the second gear 6 with the set screw, and then the second gear 6 is fixedly connected to the inner needle. Then fix the handle to be tested onto the inner needle parameter testing carrier 2 and press the handle to be tested with the clamping component 3.

[0073] A2. Connect the above-mentioned handle rotation parameters and window opening displacement testing device to the processing center, and connect the product host to the handle to be tested; wherein, the processing center is a computer, which stores testing software, and uses the testing software to read the test data of the angle sensor and displacement sensor, and calculate the corresponding parameters.

[0074] A3. To conduct the test, start the test software on the processing center and press the sampling button on the handle to be tested; after the handle stops rotating, acquire the angle data and corresponding timestamp of the angle sensor 4 of the inner needle rotation frequency test component; calculate the number of inner needle rotations based on the angle data; calculate the inner needle rotation time based on the timestamp.

[0075] Based on the angle data, the number of inner needle rotation cuts is calculated. The specific method is as follows:

[0076] Set the initial value of A to zero and the initial value of B to zero. Record the angle data in chronological order. If the difference between the current angle data and the previous angle data is greater than 1, then increment the value of A by 1; if the difference between the current angle data and the previous angle data is less than 1, then increment the value of B by 1.

[0077] The number of times the inner needle is rotated and cut is:

[0078]

[0079] C represents the number of times the inner needle is rotated and cut.

[0080] After calculating the number of inner needle rotations, determine whether the requirement for the number of rotations is met based on the number of inner needle rotations:

[0081] If the number of inner needle rotations is greater than 1, continue calculating the inner needle rotation time;

[0082] If the number of inner needle rotations is less than or equal to 1, a pop-up window will appear saying "Insufficient number of times, please measure again," and you will need to measure again.

[0083] The inner needle cutting time is calculated based on the timestamp. The specific method is as follows:

[0084] Record the angle data in chronological order, and subtract the time corresponding to the first angle data from the time corresponding to the last angle data to obtain the inner needle rotation cutting time.

[0085] A4. The frequency of inner needle rotation is calculated based on the number of inner needle rotations and the inner needle rotation time. The specific method is: inner needle rotation frequency = number of inner needle rotations / inner needle rotation time.

[0086] Example 3

[0087] This embodiment provides a method for testing handle rotation parameters, used to test the window length of the handle, such as... Figure 3 As shown, it includes:

[0088] B1. Install the second gear 6 onto the inner needle of the handle to be tested. The second gear 6 presses against the structural component on the handle. Fix the second gear 6 with the set screw, and then fix the second gear 6 to the inner needle. Then fix the handle to be tested onto the inner needle parameter testing carrier 2 and press the handle to be tested with the clamping component 3.

[0089] B2. Connect the above-mentioned handle rotation parameters and window opening displacement testing device to the processing center, and connect the product host to the handle to be tested; wherein, the processing center is a computer, which stores testing software, and uses the testing software to read the test data of the angle sensor and displacement sensor, and calculate the corresponding parameters.

[0090] B3. Adjust the handle so that the tip of the inner needle of the handle coincides with the outer edge of the window. Here, the outer edge of the window is the inner edge of the window near the tip of the outer needle.

[0091] B4. Conduct a test and use displacement sensor 7 to obtain the moving distance of the second gear 6, which is the opening length of the handle.

[0092] When the inner needle rotates, the second gear 6 moves synchronously with the inner needle. The displacement of the second gear 6 is then measured as the displacement of the inner needle. Since the inner needle initially coincides with the outer edge of the window, the distance the inner needle moves is connected to the size of the window, i.e., the length of the window.

[0093] Example 4

[0094] This embodiment provides a method for testing the rotation parameters of a handle, used to test the rotation angle and rotation time of the outer pin of the handle, such as... Figure 4 As shown, it includes:

[0095] C1. Fix the handle to be tested onto the external needle parameter testing carrier 8, and insert the external needle of the handle into the center hole of the material holder 9 and press it against the positioning pin.

[0096] C2. Connect the above-mentioned handle rotation parameters and window opening displacement testing device to the processing center, and connect the product host to the handle to be tested; wherein, the processing center is a computer, which stores testing software, and uses the testing software to read the test data of the angle sensor and displacement sensor, and calculate the corresponding parameters.

[0097] C3. Obtain the initial angle value and the corresponding timestamp, denoted as initial angle value A1 and initial time value T1;

[0098] The specific method for obtaining the initial angle value is as follows: obtain the last angle data among all angle data where the difference between the current angle value and the angle value at the previous moment is less than 0.1, and denote it as A1.

[0099] C4. Perform the test to obtain the angle data and the corresponding timestamp, which are recorded as angle value A2 and time value T2.

[0100] The specific method for obtaining angle value A2 is as follows: During the test, angle data is recorded in chronological order. When the difference between the current angle value and the angle value at the previous moment is greater than 1 for the first time, all angles D after the current angle value are obtained. In the angle data D, the angle data with the difference between the current angle data and the angle data at the previous moment being less than 0.1 for the first time is obtained in chronological order and recorded as angle value A2.

[0101] C5. Calculate the outer needle rotation angle and outer needle rotation time, specifically including:

[0102] Calculate the absolute value of the difference between A2 and A1.

[0103] If |A2-A1|≤0.1, then the test needs to be repeated;

[0104] If |A2-A1|>0.1, then the rotation angle of the outer needle is |A2-A1|, and the rotation time of the outer needle is T2-T1.

[0105] The outer needle is fixedly connected to the material holder 9. When the outer needle rotates, the material holder 9 rotates synchronously. The rotation of the material holder 9 drives the positioning pin to rotate. Therefore, the data measured by the angle sensor 4 is the rotation data of the outer needle.

[0106] The above specific embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
