Abstract
Description
Technical Field
[0001] The present invention relates to the field of amplitude measurement technology, and in particular to a device for measuring the amplitude of a debridement instrument handle. In addition, the present invention also relates to a method for measuring the amplitude of a debridement instrument handle using the device for measuring the amplitude of a debridement instrument handle. Background Art
[0002] Ultrasonic debridement handles utilize a piezoelectric ceramic's amplitude to amplify the diameter of cavitation bubbles through a variable amplitude rod. Under the influence of the ultrasonic field, the bubbles collapse and close rapidly, removing foreign matter and necrotic tissue, leaving the wound clean. The amplitude of the ultrasonic handle's variable amplitude rod directly impacts ultrasonic debridement performance, so it's essential to test the amplitude of the variable amplitude rod to select the one that meets the requirements.
[0003] Currently, there are instruments for measuring the amplitude of ultrasonic horns, called amplitude testers. However, these instruments are not well fixed, and the measured amplitude is usually within tens of microns. Even the slightest external vibration can affect the results. Furthermore, the amplitude testers are difficult to move, making it difficult to quickly and efficiently test the amplitude of tool heads in batches.

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.
[0055] Please refer to Figures 1 to 4 , Figure 1 This is a schematic structural diagram of a device for measuring the amplitude of a debridement instrument handle provided in a specific embodiment of the present invention; Figure 2 for Figure 1 A top view of Figure 3 A schematic structural diagram of another device for measuring the amplitude of a debridement instrument handle provided in a specific embodiment of the present invention; Figure 4 for Figure 3 Top view of .
[0056] In a specific embodiment, the device for measuring the amplitude of the debridement instrument handle provided by the present invention includes a slide 100, a fixing plate 700 fixed to the first end of the slide 100 for mounting the debridement handle 600, two sets of driving mechanisms 106 fixed to the second end of the slide 100 and arranged in parallel, a longitudinal fixing seat 300 for detecting the axial amplitude and a transverse fixing seat 400 for detecting the radial amplitude respectively connected to the two sets of driving mechanisms 106, and an amplitude tester 200 that can be optionally installed on the longitudinal fixing seat 300 or the transverse fixing seat 400, and the driving mechanism 106 can drive the longitudinal fixing seat 300 and the transverse fixing seat 400 to move laterally.
[0057] In the above structure, the device for measuring the amplitude of the debridement instrument handle includes a slide 100 , a fixing plate 700 , two sets of driving mechanisms 106 , a longitudinal fixing seat 300 , a transverse fixing seat 400 , and an amplitude tester 200 .
[0058] With the slide 100 as support, the fixing plate 700 is fixed to the first end of the slide 100 . Optionally, the fixing plate 700 is an L-shaped plate, and the horizontal plate of the L-shaped plate is fixed to the slide 100 by fastening screws 701 .
[0059] The upper end of the fixing plate 700 has a mounting seat 500, and the debridement handle 600 is inserted into the mounting seat 500. The upper end of the mounting seat 500 has a screw hole, and a locking screw 302 is connected to the screw hole. The bottom surface of the locking screw 302 abuts against the debridement handle 600, thereby fixing the debridement handle 600 on the fixing plate 700.
[0060] Two sets of drive mechanisms 106 are fixed to the second end of the slide 100. The two sets of drive mechanisms 106 are arranged side by side in a front-to-back manner, without interfering with each other. A longitudinal mounting base 300 and a transverse mounting base 400 are respectively connected to the two sets of drive mechanisms 106. The longitudinal mounting base 300 is used to detect axial amplitude, while the transverse mounting base 400 is used to detect radial amplitude.
[0061] The amplitude tester 200 can be optionally installed on the longitudinal fixing seat 300 or the transverse fixing seat 400. When the amplitude tester 200 is connected to the longitudinal fixing seat 300, the axial amplitude of the blade head 601 of the debridement handle 600 is detected; when the amplitude tester 200 is connected to the transverse fixing seat 400, the radial amplitude of the blade head 601 of the debridement handle 600 is detected.
[0062] The drive mechanism 106 can drive the longitudinal fixing base 300 and the transverse fixing base 400 to move laterally, thereby driving the fixing base to move the amplitude tester 200 toward or away from the debridement handle 600. When the probe 201 of the amplitude tester 200 contacts the blade 601 of the debridement handle 600 and the amplitude displayed by the amplitude tester 200 is within an acceptable amplitude range, for example, an acceptable amplitude value below 10 microns, the amplitude of the debridement handle 600 can be tested.
[0063] The device for measuring the amplitude of the debridement instrument handle provided by the present invention can detect both the axial amplitude and the radial amplitude of the blade 601 of the debridement handle 600. The amplitude detection is more specific and comprehensive, and the amplitude of the debridement handle 600 can be fully understood; the amplitude tester 200 is fixed on the longitudinal fixing seat 300 or the transverse fixing seat 400, and the amplitude tester 200 is fixed more stably; the movement of the amplitude tester 200 is controlled by the driving mechanism 106, and the position of the amplitude tester 200 can be moved slightly, and the movement is convenient to adapt to debridement handles 600 of different lengths; the debridement handles 600 that meet the requirements can be screened out quickly and in batches, thereby improving work efficiency, reducing the defective rate of the entire machine, and saving manpower, material resources and time costs.
[0064] Based on the above specific embodiment, the driving mechanism 106 includes a motor driving mechanism 106 and a handwheel driving mechanism 106 .
[0065] The motor drive mechanism 106 includes a motor, a pressure sensor, and a controller. The pressure sensor is mounted on the mounting base 500 of the fixing plate 700 and can detect the pressure detected by the debridement handle 600 mounted on the mounting base 500. The controller is electrically connected to the pressure sensor and the motor. Optionally, the controller is an MCU.
[0066] In the control mode of the handwheel drive mechanism 106, when the handwheel is rotated clockwise or counterclockwise, the fixed seat will drive the amplitude tester 200 to move toward or in the opposite direction of the debridement handle 600. When the probe 201 contacts the blade 601, the handwheel is slightly rotated according to the data displayed on the amplitude tester 200 until the data displayed on the amplitude tester 200 is below 10 microns. Click the reset button on the amplitude tester 200 to turn on the ultrasonic debridement function and observe the handle amplitude measured by the amplitude tester 200.
[0067] In the control mode of the motor drive mechanism 106, the pressure sensor on the mounting base 500 detects that the debridement handle 600 is fixed and sends it to the controller. The controller detects the amplitude value of the amplitude tester 200 and controls the motor to rotate to drive the fixing base to move. When the amplitude tester 200 contacts the blade head 601 and the amplitude value is between 0 and 10 microns, the controller controls the motor to stop rotating and determines whether the value of the amplitude tester 200 exceeds the measurement range. If it does not exceed the measurement range, the debridement instrument is automatically reset to zero, and then the debridement function is turned on to test the amplitude of the debridement handle 600. After reaching stability, the amplitude of the debridement handle 600 and the debridement handle 600 number are saved in the memory of the controller. At the same time, if the amplitude does not meet the requirements, a prompt is issued and the compliance is also written to the memory. In this way, multiple debridement instrument handles can be tested at once. After the test is completed, the data of each debridement handle 600 stored in the memory is sent to the computer, and the debridement handle 600 that meets the requirements can be screened by reviewing these data.
[0068] By applying the technical solution provided in the embodiment of the present invention, the position of the amplitude tester 200 is automatically controlled by a program to measure the amplitude of the debridement handle 600, and the debridement handles 600 that meet the requirements can be quickly and batch-screened, thereby improving work efficiency, reducing the defective rate of the entire machine, and saving manpower, material resources and time costs.
[0069] The motor drive mechanism 106 includes at least two options. In the first option, the motor drive mechanism 106 includes a stepper motor, a transmission screw 104, and a sliding block 105. The transmission screw 104 is connected to the output shaft of the stepper motor. The sliding block 105 is mounted on the transmission screw 104. The longitudinal fixing seat 300 and the transverse fixing seat 400 are fixed to the sliding block 105 via locking screws 301. The transmission screw 104 is a type of slide rail 103, and the slide rail 103 can also be a drive rod.
[0070] The motor is a stepper motor, which can be subdivided and controlled to improve the motor's accuracy and stability. The stepper motor has a reduction gear in front, which can further reduce the stepper motor's rotation speed. The gear can reduce the distance the stepper motor drives the slide 103 forward with each step, thereby achieving micron-level movement.
[0071] In the second case, the motor drive mechanism 106 includes a linear motor, and the longitudinal fixing seat 300 and the transverse fixing seat 400 are connected to the output shaft of the linear motor, and the longitudinal fixing seat 300 and the transverse fixing seat 400 are driven to move by the output shaft of the linear motor.
[0072] Optionally, the motor drive mechanism 106 includes a T-slot 101 fixed to the slide 100. The longitudinal fixing seat 300 and the transverse fixing seat 400 are provided with guide blocks that mate with the T-slot 101. After connection, the guide blocks engage in the T-slot 101 and slide along the T-slot 101, providing guidance and limiting functions, ensuring that the fixing seat moves in a straight line and reducing shaking.
[0073] The driving mode of the stepping motor and the driving mode of the linear motor can both be applied to the longitudinal fixing seat 300 and the transverse fixing seat 400 .
[0074] Based on the above-described specific embodiment, the T-slot 101 has multiple positioning holes 102, and the longitudinal fixing seat 300 and the transverse fixing seat 400 have threaded holes that match the positioning holes 102. After the longitudinal fixing seat 300 and the transverse fixing seat 400 are adjusted, they are fixed to the T-slot 101 using positioning bolts. In other words, when driven by a linear motor, the fixing seat can be manually adjusted to the test position of the debridement instrument handle and then fixed using the positioning holes 102, improving reliability.
[0075] Corresponding to the above device embodiment, an embodiment of the present invention further provides a method for measuring the amplitude of a debridement instrument handle. The method for measuring the amplitude of a debridement instrument handle described below and the device based on measuring the amplitude of a debridement instrument handle described above can be referenced to each other.
[0076] See also Figure 5 FIG. 1 is a flowchart illustrating a method for measuring the amplitude of a debridement instrument handle according to an embodiment of the present invention. The method is applicable to any of the aforementioned devices for measuring the amplitude of a debridement instrument handle. A debridement handle 600 is mounted on a mounting base 500 of a fixing plate 700, and is pressed against a pressure sensor in the mounting base 500. An amplitude meter 200 is secured to the mounting base via a hand-tightening locking screw 302. The amplitude meter 200 can be selectively mounted on either the longitudinal mounting base 300 or the transverse mounting base 400. During installation, the probe 201 of the amplitude meter 200 is aligned with the blade 601 of the debridement handle 600 to ensure that the probe 201 of the amplitude meter 200 accurately detects the amplitude of the blade 601 of the debridement handle 600.
[0077] The method may include the following steps:
[0078] S110: Acquire the actual pressure value detected by the pressure sensor;
[0079] In actual application, the debridement handle 600 is inserted into the mounting seat 500. There is a locking screw 302 above the mounting seat 500. The locking screw 302 has the function of fixing the debridement handle 600. There is a pressure sensor at the mounting seat 500. The pressure sensor below the debridement handle 600 detects the actual pressure value.
[0080] S120: When the actual pressure value reaches a preset pressure value, the amplitude tester 200 is controlled to move closer to the blade 601 of the debridement handle 600. The preset pressure value is a normal pressure value when the debridement handle 600 is installed.
[0081] In practice, when the locking screw 302 is manually tightened to a certain degree, that is, when the actual pressure value reaches the preset pressure value and is sent to the controller, the controller prompts the operator through the display that the debridement handle 600 is secure. At the same time, the amplitude tester 200 is mounted on the fixing base and controlled to move closer to the blade 601 of the debridement handle 600.
[0082] The preset pressure value is a normal pressure value when the debridement handle 600 is installed. The preset pressure value is obtained by recording the pressure when the debridement handle 600 is locked by tightening the screw top 302 for multiple times, taking an average value, and saving it in the controller.
[0083] S130: When the amplitude value of the amplitude tester 200 is within the acceptable amplitude value range, the amplitude tester 200 is controlled to stop moving. The acceptable amplitude value is the amplitude value when the amplitude tester 200 contacts the cutter head 601;
[0084] In actual application, the amplitude tester 200 is driven by the driving mechanism 106 and approaches the blade 601 of the debridement handle 600 until the amplitude value of the amplitude tester 200 is within the acceptable amplitude value range. Usually, the amplitude value of the amplitude tester 200 is between 0-10 microns, then the stepper motor is stopped, and it is considered that the probe 201 of the amplitude tester 200 and the blade 601 of the debridement handle 600 are just in contact and the contact is intact.
[0085] S140 : Control the amplitude tester 200 to detect the amplitude value of the debridement handle 600 .
[0086] In actual application, after the probe 201 contacts the blade head 601 , the amplitude tester 200 is reset to zero, the ultrasonic debridement function is turned on, and the amplitude tester 200 detects the amplitude of the debridement handle 600 .
[0087] By applying the method provided in the embodiment of the present invention, it is possible to quickly and in batches screen out debridement handles 600 that meet the requirements, thereby improving work efficiency, reducing the defective rate of the entire machine, and saving manpower, material resources, and time costs.
[0088] In the embodiment of the present invention, controlling the amplitude tester 200 to approach the blade 601 of the debridement handle 600 may include:
[0089] When the distance between the amplitude tester 200 and the cutter head 601 is x, the amplitude tester 200 is controlled to approach the cutter head 601 at a first speed, where x is the rapid moving distance between the probe 201 and the cutter head 601;
[0090] When the distance between the amplitude tester 200 and the cutter head 601 is z, the amplitude tester 200 is controlled to decelerate and approach the cutter head 601 at a speed of k·z, where k is the deceleration ratio and z is the deceleration moving distance from the probe 201 to the cutter head 601;
[0091] When the speed is reduced to 0 and the probe 201 still does not contact the tool head 601 , the amplitude tester 200 is controlled to move at a second speed, which is smaller than k·z.
[0092] For ease of description, the above steps are combined for illustration.
[0093] In practical applications, the slide rail 103 is taken as the x-axis, and the sliding block 105 at the second end of the slide table 100 is taken as the origin. Figure 8 As shown, the distance between the two threads of the transmission screw 104 is D, that is, when the motor rotates one circle, the sliding block 105 moves forward a distance D. Figure 8 Where a is the distance from the probe 201 to the origin. The controller records the current position coordinates of the probe 201 (n·D+a, 0) in real time based on the number of revolutions of the stepper motor, where n is the number of revolutions of the stepper motor. The distance w between the debridement instrument handle blade 601 and the origin is measured and stored in the controller's memory. These distances are measured to better control the movement speed of the slider 105.
[0094] When the sliding block 105 is far away from the cutter head 601 , the rotation speed of the stepper motor can be set to be relatively high to save time.
[0095] When the sliding block 105 is only a distance z from the cutter head 601 , the stepper motor decelerates at a speed of k·z, where k is a deceleration ratio obtained through multiple tests, and slowly moves the probe 201 to the cutter head 601 , facilitating precise control of the position of the probe 201 .
[0096] If the probe 201 still does not touch the cutter head 601 when the speed is reduced to 0, it continues to move at a lower speed, such as 1 micron per second, until the amplitude value of the amplitude tester 200 is between 0-10 microns, then stops the stepper motor, and accurately controls the distance between the probe 201 and the cutter head 601 to improve the accuracy of the amplitude test.
[0097] In the embodiment of the present invention, k and z can be determined by the following method:
[0098] S101, obtain ki value and zi value;
[0099] S102, when the amplitude tester 200 moves to the point where the probe 201 is 601 zi away from the tool head, the amplitude tester 200 is controlled to decelerate at a speed of ki·zi;
[0100] S103, when the amplitude tester 200 stops moving, obtaining the display value of the amplitude tester 200;
[0101] S104, when the displayed value is greater than the acceptable amplitude value or equal to 0, determine new ki and zi values according to the preset rules, and return to S101;
[0102] When the displayed value is within the acceptable amplitude value range, the ki value and the zi value are determined to be the k value and the z value.
[0103] For ease of description, the above steps are combined for illustration.
[0104] In practical applications, the method for determining the k value and the z value is as follows: first, a k1 and a z1 are given. When the stepper motor reaches a distance of z1 from the cutter head 601, it is decelerated at a speed of k1·z1, and the display value of the amplitude tester 200 is observed at the same time. When the stepper motor stops rotating, if the display value of the amplitude tester 200 is large, greater than the unacceptable amplitude value, such as greater than 10um, or the display value of the amplitude tester 200 is 0, then the k1 and z1 values are discarded. At the same time, based on the values displayed by the amplitude tester 200, it can be determined whether the values of k and z need to be increased or decreased based on k1 and z1. After determining the change direction of k and z, a new k2 and z2 are given, and the test is continued according to the above method until a set of k and z values is reached. When the probe 201 contacts the blade 601, the amplitude tester 200 displays a value between 0-10um, ensuring that the probe 201 is accurately decelerated to the appropriate position, saving movement time, protecting the amplitude tester 200 and the debridement handle 600, and preventing collisions.
[0105] In the embodiment of the present invention, determining new ki values and zi values according to preset rules may include:
[0106] When the displayed value is 0, increase the ki and zi values;
[0107] When the displayed value is greater than the acceptable amplitude value, reduce the ki and zi values.
[0108] In actual applications, based on the value displayed by the amplitude tester 200, it can be determined whether the values of k and z need to be increased or decreased based on k1 and z1. Specifically, if the value displayed by the amplitude tester 200 is 0, the values of k1 and z1 are increased. If the value displayed by the amplitude tester 200 is greater than 10um, the values of k and z are reduced. This method can quickly determine the k value and z value.
[0109] In an embodiment of the present invention, the controller includes a memory and a display, and controlling the amplitude tester 200 to detect the amplitude value of the debridement handle 600 may include the following steps:
[0110] Control the amplitude tester 200 to reset to zero;
[0111] Turn on the debridement handle 600 and detect the amplitude value of the debridement handle 600;
[0112] After the amplitude value tested by the amplitude tester 200 is stable, the serial number, amplitude value and qualified judgment result of the debridement handle 600 are saved in the memory;
[0113] The serial number, amplitude value and qualified judgment result of the debridement handle 600 are displayed on the display;
[0114] Controlling the amplitude tester 200 to return to the original position;
[0115] Import data from the storage into the terminal device in batches.
[0116] like Figure 6 As shown, Figure 6 This is a control block diagram of the controller. The controller detects the status of the debridement handle 600 according to the sensor at the mounting base 500 to determine whether the debridement handle 600 is fixed. The amplitude value of the amplitude tester 200 is sent to the controller through the communication line.
[0117] The controller includes a display, which can set the motor speed, input the debridement instrument handle number, display the amplitude value of the amplitude tester 200, and display whether the debridement handle 600 is in place.
[0118] The stepper motor control is that the controller controls the stepper motor to rotate and drive the fixed seat on the slide rail 103 to move forward or backward.
[0119] The debridement handle 600 data output can output batches of debridement handle 600 test data to a terminal device.
[0120] like Figure 7 As shown, Figure 7The following is a control flow chart of a method for measuring the amplitude of a debridement instrument handle according to a specific embodiment. After the debridement handle 600 is inserted into the mounting base 500, it is secured with the locking screw 302. A pressure sensor is located below the insertion hole of the debridement handle 600. When the locking screw 302 compresses the debridement handle 600 to a certain degree and the actual pressure detected by the pressure sensor reaches a preset value, the pressure is transmitted to the controller, which then notifies the operator via a display that the debridement handle 600 is securely secured. The operator can enter the debridement handle 600 serial number or enter the serial number after the test is complete. When the controller detects that the pressure has stabilized, it delays for a specified period and then begins controlling the stepper motor to rotate. When the probe 201 contacts the blade 601, the controller resets the amplitude meter 200 and activates the ultrasonic debridement function. After the amplitude measured by the amplitude meter 200 stabilizes, the controller stores the debridement handle 600 serial number, the current amplitude value, and whether it meets the requirements in memory and displays them on the display. After recording is completed, the controller controls the stepper motor to return the amplitude tester 200 to the original position. When the operator needs to import data into the computer in batches, he can click the control button on the display and connect the computer to the device through the communication line.
