[0035] like Figure 2 As shown, the symbiotic sensor 100 includes a fixing module 10, a contact position detection module 20 and a three-dimensional force sensing module 30; the fixing module 10 is used to connect with the handheld medical device 1000; the contact position detection module 20 includes a plurality of contact sensing units 21, and the plurality of contact sensing units 21 are arranged on the surface of the fixing module 10 to confirm the contact position; the three-dimensional force sensing module 30 includes a plurality of photoelectric units 31, and the plurality of photoelectric units 31 are symmetrically arranged on the surface of the fixing module 10 to confirm the multi-dimensional force generated during contact.

[0036] Specifically, the handheld medical device 1000 may include a symmetric sensor 100 and a basic configuration module for implementing the handheld medical device 1000, and the basic configuration module may be adapted according to the application scenario of the handheld medical device 1000. For example, the handheld medical device 1000 may be applied to a radio frequency therapeutic device, and the radio frequency therapeutic device may include a host device and a handheld medical device 1000 connected to the host device, and the handheld medical device 1000 is provided with a symmetric sensor 100 and an electromagnetic module, which is one of the basic configuration modules and is used to provide electromagnetic waves. The handheld medical device 1000 may also be applied to an ultrasonic therapeutic device, and the ultrasonic therapeutic device may include a host device and a handheld medical device 1000 connected to the host device, and the handheld medical device 1000 is provided with a symmetric sensor 100 and an ultrasonic module, which is one of the basic configuration modules and is used to provide ultrasonic waves.

[0037] The eutectic sensor 100 may include a fixing module 10, a contact position detection module 20, and a three-dimensional force sensing module 30. Figure 2 As shown, the fixing module 10 is used to fix the contact position detection module 20 and the three-dimensional force sensing module 30, which may include a contact surface for contacting the patient's skin, and the contact position detection module 20 and the three-dimensional force sensing module 30 are both installed on the contact surface.

[0038] The contact position detection module 20 may include a plurality of contact sensing units 21, and the plurality of contact sensing units 21 are arranged at intervals on the contact surface of the fixing module 10. The number of the contact sensing units 21 may be set according to the application scenario of the handheld medical device 1000 and the size of the fixing module 10, and the number may range from a few to a dozen to dozens. The contact sensing unit 21 is mainly used to confirm the contact position with the patient's skin so as to confirm whether it is completely in contact with the patient's skin. Therefore, the contact sensing units 21 may be distributed on the contact surface of the fixing module 10 to facilitate confirmation of the contact position.

[0039] The three-dimensional force sensing module 30 includes a plurality of photoelectric units 31, and the plurality of photoelectric units 31 can be symmetrically arranged on the contact surface of the fixed module 10. The number of photoelectric units 31 can also be set according to the application scenario of the handheld medical device 1000 and the size of the fixed module 10, and the number can range from a few to a dozen to dozens. The photoelectric unit 31 is mainly used to measure the size of the force applied by the doctor to the handheld medical device 1000, so that the doctor can adjust the applied force to meet the treatment or detection requirements. The three-dimensional force sensing module 30 is used to detect the three-dimensional force applied by the doctor to the handheld medical device 1000, that is, the component force along the X-axis, the component force along the Y-axis, and the component force along the Z-axis.

[0040] See also Figure 2 and Figure 3 As a further embodiment, the fixing module 10 includes an elastic detection frame 11; the elastic detection frame 11 is hollow to form an installation space 12, and the installation space 12 is used to set the contact sensor unit 21 and the photoelectric unit 31.

[0041] The fixing module 10 may include an elastic detection frame 11, and the surface of the elastic detection frame 11 is the contact surface. The elastic detection frame 11 is hollow to form an installation space 12, and the installation space 12 is located between the top and the bottom of the elastic detection frame 11, and the installation space 12 is used to install the contact sensor unit 21 and the photoelectric unit 31.

[0042] like Figure 2As shown, the elastic detection frame 11 can be a rectangular frame, and an opening is provided in the middle area of ​​the rectangular frame, and the opening is used to install the basic configuration module of the handheld medical device 1000, and a contact sensor unit 21 and a photoelectric unit 31 are provided along the four sides of the opening. Part of the structure of the contact sensor unit 21 and the photoelectric unit 31 is exposed from the elastic detection frame 11, so as to fit the patient's skin to realize the detection of the contact position and force. Figure 2 The elastic detection frame 11 may include four sides, each of which is provided with two contact sensing units 21 and one photoelectric unit 31, and the two contact sensing units 21 are respectively located on both sides of the photoelectric unit 31, so a total of eight contact sensing units 21 and four photoelectric units 31 are provided on one elastic detection frame 11. It should be noted that the setting positions and numbers of the contact sensing units 21 and the photoelectric units 31 are not limited to the above settings, and the positions and numbers of the contact sensing units 21 and the photoelectric units 31 can be adjusted according to the application field of the handheld medical device 1000. For example, the number of the contact sensing units 21 and the photoelectric units 31 on each side can be increased or decreased, or the relative positions of the contact sensing units 21 and the photoelectric units 31 can be changed.

[0043] See also Figure 4 and Figure 5 As a further embodiment, the contact sensing unit 21 includes a metal elastic member 22 and a plurality of electrodes 23; the plurality of electrodes 23 are all arranged in the elastic detection frame 11, and the plurality of electrodes 23 are connected to the circuit module of the handheld medical device 1000; the metal elastic member 22 is arranged in the installation space 12 and is located above the plurality of electrodes 23, and part of the metal elastic member 22 is also exposed from the elastic detection frame 11.

[0044] The contact sensing unit 21 is used to confirm the contact position so as to confirm whether the handheld medical device 1000 is completely in contact with the patient's skin. The contact sensing unit 21 may include a metal elastic member 22 and a plurality of electrodes 23. The metal elastic member 22 and the plurality of electrodes 23 may be disposed in the elastic detection frame 11, that is, the metal elastic member 22 and the electrodes 23 may be embedded in the elastic detection frame 11. At the same time, the plurality of electrodes 23 are also connected to the circuit module of the handheld medical device 1000. For example, Figure 4As shown, three electrodes 23 may be included. The three electrodes 23 are sequentially arranged in the elastic detection frame 11, and the electrode 23 on the left and the electrode 23 on the right are connected to the positive electrode of the circuit module, and the electrode 23 in the middle is connected to the negative electrode of the circuit module. The metal elastic member 22 is arranged above the three electrodes 23, and the metal elastic member 22 includes a first contact portion, a second contact portion and a pressing portion. The first contact portion is located above the left electrode 23, the second contact portion is located above the right electrode 23, and the pressing portion is located above the middle electrode 23. At the same time, the pressing portion is also exposed to the elastic detection frame 11. When the handheld medical device 1000 contacts the patient's skin, the pressing portion is squeezed and contacts the electrode 23 in the middle. At the same time, the first contact portion and the second contact portion also contact the corresponding electrodes 23, so that the three electrodes 23 are connected to the circuit module, thereby allowing current to pass, as shown in FIG. Figure 5 When the three electrodes 23 are connected to the circuit module, the signal acquisition circuit in the circuit module can detect the connection information, and then confirm the contact information.

[0045] like Figure 2 As shown, when the electrode 23 of any one of the contact sensor units 21 is connected to the circuit module, the handheld medical device 1000 can detect the information that the corresponding contact sensor unit 21 is in contact with the patient's skin. If, during the process of the handheld medical device 1000 being fitted between the patient's skin, the electrode 23 of the contact sensor unit 21 is not connected to the circuit module, it indicates that the corresponding contact sensor unit 21 is not completely fitted between the patient's skin. The relevant information can be displayed on the host computer, and the doctor can adjust the contact position according to the information displayed by the host device to achieve complete fitting.

[0046] See also Figure 6 As a further embodiment, the contact sensing unit 21 includes a resistive pressure film 24; the resistive pressure film 24 includes a sensing portion 241 and a convex portion 242, the sensing portion 241 is disposed in the elastic detection frame 11, and the convex portion 242 is disposed on the sensing portion 241 and exposed to the elastic detection frame 11.

[0047] The contact sensing unit 21 may include a resistive pressure film 24, which may include a sensing portion 241 and a convex portion 242. The sensing portion 241 is embedded in the elastic detection frame 11, and the convex portion 242 is disposed on the sensing portion 241 and connected to the sensing portion 241, and part of the convex portion 242 is exposed to the elastic detection frame 11. When the handheld medical device 1000 contacts the patient's skin, the convex portion 242 is squeezed to generate pressure, thereby changing the resistance value of the sensing portion 241, and the sensing portion 241 is also connected to the circuit module. The circuit module detects that the resistance value of the sensing portion 241 has changed, and the change in pressure and intensity can be calculated by calculating the change in resistance value, thereby obtaining contact information. For example, the circuit module may include a voltage differential circuit, and the change in pressure and intensity is calculated by the voltage differential circuit.

[0048] See also Figure 7 As a further embodiment, the contact sensing unit 21 includes a first photoelectric sensor 25, an elastic member 26 and a first reflective member 27; one end of the first photoelectric sensor 25 and the elastic member 26 are both arranged in the elastic detection frame 11, and the other end of the elastic member 26 is provided with the first reflective member 27, and the first photoelectric sensor 25 is used to detect the change in distance between it and the reflective member to confirm the deformation amount of the elastic member 26.

[0049] The contact sensing unit 21 may include a first photoelectric sensor 25, an elastic member 26, and a first reflective member 27. One end of the first photoelectric sensor 25 and the elastic member 26 are both disposed in the elastic detection frame 11, and the other end of the elastic member 26 abuts against the first reflective member 27. The top of the first reflective member 27 is exposed from the elastic detection frame 11 to facilitate abutment against the patient's skin. The surface of the first reflective member 27 has a high reflectivity and can reflect back the light emitted by the first photoelectric sensor 25.

[0050] When the handheld medical device 1000 contacts the patient's skin, the first reflector 27 is subjected to pressure and squeezes the elastic member 26, causing the elastic member 26 to deform and shrink, thereby reducing the distance between the first reflector 27 and the first photoelectric sensor 25. The first photoelectric sensor 25 emits a light signal to the first reflector 27 in real time, and the first reflector 27 reflects the light signal back to the first photoelectric sensor 25, which receives the reflected light signal. When the distance between the first photoelectric sensor 25 and the first reflector 27 is shortened, the time for the first photoelectric sensor 25 to receive the reflected light signal is also shortened synchronously, so that the distance between the first photoelectric sensor 25 and the first reflector 27 can be converted into the deformation amount of the elastic member 26, and then the deformation amount can be measured according to the light signal, so that the pressure change can be obtained, and the contact information can be detected.

[0051] See also Figure 8As a further embodiment, the photoelectric unit 31 includes a second photoelectric sensor 32 and a second reflector 33; the second photoelectric sensor 32 is arranged in the installation space 12, and the second reflector 33 is arranged through the elastic detection frame 11 and is located above the second photoelectric sensor 32.

[0052] The photoelectric unit 31 may include a second photoelectric sensor 32 and a second reflector 33. The second photoelectric sensor 32 is disposed in the installation space 12. The second reflector 33 penetrates the elastic detection frame 11, and one end of the second reflector 33 is exposed from the elastic detection frame 11, and the other end is located above the second photoelectric sensor 32 and maintains a preset distance from the second photoelectric sensor 32. The preset distance is the initial distance between the second photoelectric sensor 32 and the second reflector 33. When in use, the initial distance between the second photoelectric sensor 32 and the second reflector 33 needs to be accurately measured to optimize the resolution of the second photoelectric sensor 32.

[0053] The second photoelectric sensor 32 may include a light generator and a light sensor, wherein the light generator is used to emit a light signal to the surface of the second reflector 33, and the light sensor is used to receive the light signal reflected by the second reflector 33. The surface of the second reflector 33 has a high reflectivity and is used to reflect the light signal. The second reflector 33 may be a cylinder, and both the bottom and the side of the cylinder have a high reflectivity and can reflect the light signal back to the second photoelectric sensor 32. At the same time, the surface of the second reflector 33 may also be provided with a thread, so as to facilitate the adjustment of the initial distance between the second reflector 33 and the second photoelectric sensor 32 by rotation.

[0054] When the handheld medical device 1000 contacts the patient's skin, the elastic detection frame 11 will deform. Depending on the direction of the applied force, the elastic detection frame 11 will deform in different directions, thereby causing the second photoelectric sensor 32 to rotate. Fig.10 As shown, Fig.10 There are four photoelectric units 31, which are respectively denoted as No. 1 photoelectric unit 31, No. 2 photoelectric unit 31, No. 3 photoelectric unit 31 and No. 4 photoelectric unit 31. When the elastic detection frame 11 is subjected to the force in the X direction, the second photoelectric sensor 32 is also subjected to the force in the X direction, and its upper surface may have a tendency to rotate around the Y axis, and then its structure is slightly deformed, resulting in a change in the output signal outputted by it, that is, when subjected to the force in the X direction, the No. 2 photoelectric unit 31 and the No. 4 photoelectric unit 31 are slightly deformed, and the corresponding output signals of the No. 2 photoelectric unit 31 and the No. 4 photoelectric unit 31 change, while the output signals of the No. 1 photoelectric unit 31 and the No. 3 photoelectric unit 31 remain unchanged.

[0055] When the elastic detection frame 11 is subjected to the force in the Y direction, the second photoelectric sensor 32 is also subjected to the force in the Y direction, and its upper surface may have a tendency to rotate around the X axis, so that its structure undergoes a slight deformation, resulting in a change in the output signal outputted by it. That is, when subjected to the force in the Y direction, photoelectric unit No. 1 31 and photoelectric unit No. 3 31 will undergo a slight deformation, and the output signals of photoelectric unit No. 1 31 and photoelectric unit No. 3 31 will change accordingly, while the output signals of photoelectric unit No. 2 31 and photoelectric unit No. 4 31 remain unchanged.

[0056] When the elastic detection frame 11 is subjected to a force in the Z direction, the second photoelectric sensor 32 is also subjected to a force in the Z direction, the photoelectric units 31 No. 1 to 31 No. 4 are all raised or lowered at the same time, and the output signals of the four photoelectric units 31 are all changed.

[0057] The force exerted on the second photoelectric sensor 32 can be calculated by the following formula:

[0058]

[0059] Among them, v 1 、v 2 、v 3 and v 4 They represent the output signals of the photoelectric unit 31 No. 1, the photoelectric unit 31 No. 2, the photoelectric unit 31 No. 3, and the photoelectric unit 31 No. 4, respectively. K is the 3-matrix of sensor force value calculation and decoupling obtained through the calibration process. F x is the force on the second photoelectric sensor 32 in the X-axis, F y is the force on the second photoelectric sensor 32 in the Y axis, F z is the force received by the second photoelectric sensor 32 in the Z axis.

[0060] See also Figure 2 As a further embodiment, it also includes an overload protection module 40 , and the overload protection module 40 is set throughout the elastic detection frame 11 .

[0061] The overload protection module 40 may be arranged at the connection of the four sides of the elastic detection frame 11, that is, four overload protection modules 40 may be arranged on the surface of the elastic detection frame 11. The overload protection module 40 is arranged through the elastic detection frame 11, and the bottom end of the overload protection module 40 does not contact the inside of the elastic detection frame 11, that is, there is a gap between the bottom end of the overload protection module 40 and the inside of the elastic detection frame 11, and the gap is the maximum force that the elastic detection frame 11 can withstand. When the handheld medical device 1000 contacts the patient's skin, the overload protection module 40 is squeezed, thereby shortening the distance with the inside of the elastic detection frame 11. When the overload protection module 40 abuts against the inside of the elastic detection frame 11, the maximum force that the elastic detection frame 11 can withstand is reached, and the overload protection module 40 shares the force on the elastic detection frame 11, thereby avoiding irreversible plastic deformation of the elastic detection frame 11 and the photoelectric unit 31.

[0062] See also Fig. 9 As a further embodiment, the overload protection module 40 includes an overload protection rod 41 , and the overload protection rod 41 is disposed through the elastic detection frame 11 .

[0063] Among them, Fig. 9 As shown, the overload protection module 40 may include an overload protection rod 41, which is arranged to penetrate the elastic detection frame 11, and a gap is left between the bottom of the overload protection rod 41 and the bottom of the installation space 12, and the gap is used to limit the maximum force that the elastic detection frame 11 can withstand. When the overload protection rod 41 is squeezed, the gap between it and the bottom of the installation space 12 is shortened until it abuts against the bottom of the installation space 12. When the overload protection rod 41 abuts against the bottom of the installation space 12, the overload protection rod 41 shares the force exerted on the elastic detection frame 11.

[0064] like Fig.11 and Fig.12 As shown, Fig.11 The handheld medical device 1000 is not in complete contact with the patient's skin, and its contact position and contact force can be measured by the contact position detection module 20 and the three-dimensional force sensing module 30, as shown by the arrows. The incomplete contact can be represented by the brightness and distribution of the corresponding area in the upper computer software, such as Fig.12 shown.
