[0002] Laser medicine is a technology that uses the characteristics of lasers for medical diagnosis and treatment. Laser medicine has become an important branch of medicine and an important branch of laser technology application. The application directions of laser medical equipment (Medical Lasers) include: cosmetic dermatology (such as scar repair, skin resurfacing, laser hair removal, tattoo removal); ophthalmology (including Lasik and laser photocoagulation); dentistry; angioplasty; cancer diagnosis, cancer treatment; dermatology (treatment of melanoma); frenectomy; lithotripsy; laser mammography; medical imaging, microscopy, optical coherence tomography; optogenetics; prostatectomy; plastic surgery (laser liposuction, congenital and acquired skin injuries, burns and surgical scars); surgery (cutting, ablation and burning tissue), etc.

[0003] Different handpiece treatment heads are used for products in different departments or for different indications of the same product, so different handpiece treatment heads need to be replaced. During the treatment process, the operator's accurate selection of the handpiece treatment head and the correct connection of the handpiece treatment head play a vital role in the safe and effective implementation of the operation.

[0004] If the handpiece treatment tip is used properly, it can allow the operator to complete more complex tasks safely and effectively, such as reducing blood loss, reducing postoperative discomfort, reducing the chance of wound infection, and achieving better wound healing.

[0005] If the handpiece treatment head is used improperly, it may lead to risks such as abuse of clinical indications, mismatch of treatment parameters, prolonged treatment time, and unexpected laser output.

[0006] At present, the commonly used hardware solution for handpiece connection detection is to use a Hall sensor. This solution requires the integration of a magnetic field element at the handpiece treatment head and a Hall switch at the other end. The equipment manufacturing cost is relatively high.

[0039] The following description provides specific application scenarios and requirements of the present application, with the purpose of enabling those skilled in the art to make and use the content in the present application. It will be apparent to those skilled in the art that various local modifications to the disclosed embodiments are apparent, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the present application. Therefore, the present application is not limited to the embodiments shown, but to the widest scope consistent with the claims.

[0040] In view of the problems that the existing connection detection scheme for the hand therapy head has high requirements for the structural configuration, large system complexity and high overhead, the technical solution of the present application is to respectively configure connectors for the main unit of the laser medical device and the hand therapy head. By making simple circuit connections to the pins of the connectors, the main unit of the laser medical device can perform electrical connection detection on the hand therapy head, thereby identifying the connection status of the hand therapy head and the laser medical device.

[0041] The detection circuit of the hand tool treatment head of the first embodiment of the present application can be found in Figure 1 The detection circuit of the hand tool treatment head is applied to laser medical equipment, and includes: a first connector, a second connector and a first resistor R1.

[0042] The host of the laser medical device is configured with the first connector, the first connector is configured with a first pin PIN1 and a third pin PIN3, the first pin PIN1 is connected to the power supply terminal VCC through the first resistor R1, and the third pin PIN3 is grounded GND.

[0043] The hand tool treatment head is configured with the second connector, the second connector is configured with a second pin PIN2 and a fourth pin PIN4, the second pin PIN2 and the fourth pin PIN4 are short-circuited, that is, the second pin PIN2 and the fourth pin PIN4 are directly connected.

[0044] When the first connector is connected to the second connector, for example, by plugging, the first pin PIN1 is connected to the second pin PIN2, and the third pin PIN3 is connected to the fourth pin PIN4.

[0045] The host is configured with an input port, and the input port is connected to the first pin PIN1 and is used to read the electrical state of the first pin PIN1 to determine the connection state between the hand tool treatment head and the host.

[0046] In this embodiment, the host of the laser medical device includes a microcontroller, and the microcontroller is configured with a general purpose input / output port (GPIO, General Purpose I / O Ports). The general purpose input / output port is set as the input port and connected to the first pin PIN1 for reading the level state of the first pin.

[0047] Combination Figure 1 The connection status detection of the hand tool treatment head of this embodiment is described as follows: the microcontroller in the host, i.e., the single-chip microcomputer MCU, provides a general-purpose input and output port GPIO, which is used to read the connection status of the hand tool treatment head and is configured as an input mode, i.e., used to read the level status of the detection point P1 (i.e., the GPIO pin in this embodiment). The GPIO pin is configured with a first resistor R1 to the power supply terminal VCC. The GPIO (input port) of the MCU is at a high level when the hand tool treatment head is not connected (the first connector and the second connector are not connected). The host end is matched with the second connector of the hand tool treatment head through the first connector. The pins of the first connector of the host end are the first pin PIN1 and the third pin PIN3. The first pin PIN1 is connected to the detection point P1, and the third pin PIN3 is connected to the ground GND. The pins of the second connector of the hand tool treatment head are the second pin PIN2 and the fourth pin PIN4. The second pin PIN2 and the fourth pin PIN4 of the second connector of the hand tool treatment head are short-circuited by a wire. When the hand therapy head is connected to the host, that is, the first pin PIN1 and the second pin PIN2 are connected, and the third pin PIN3 and the fourth pin PIN4 are connected, then the detection point P1 is connected to the ground GND, and the level of the detection point P1 is low. By configuring the MCU program, it can be defined that when the level of the detection point P1 is high, the hand therapy head is not connected. At this time, the connection status of the hand therapy head can be displayed on the human-computer interaction interface and the laser output can be disabled by configuring the corresponding program; when the level of the detection point P1 is low, the hand therapy head is judged to be connected, and the ready state of the hand therapy head and the laser output can be enabled on the human-computer interaction interface by configuring the corresponding program.

[0048] It should be noted that Figure 1The first pin PIN1 shown is connected to the power supply terminal VCC through the first resistor R1 and the third pin PIN3 is grounded GND, wherein the first resistor R1 is used as a pull-up resistor to pull up the detection point P1 to a high level when the hand tool is not connected to the host. Those skilled in the art can understand that the first resistor R1 can also be used as a pull-down resistor to pull down the detection point P1 to a low level when the hand tool is not connected to the host, that is, the first pin PIN1 is grounded GND through the first resistor R1 and the third pin PIN3 is connected to the power supply terminal VCC. At this time, the MCU program is configured to define that when the level of the detection point P1 is low, the hand tool treatment head is not connected; when the level of the detection point P1 is high, it is judged that the hand tool treatment head is in a connected state.

[0049] Please refer to the detection circuit of the hand tool treatment head of the second embodiment of the present application. Figure 2 Different from the detection circuit described in the first embodiment, an electronic component is connected between the second pin PIN2 and the fourth pin PIN4 of the second connector of the hand tool treatment head in this embodiment.

[0050] Based on the circuit analysis of the first embodiment, when the hand tool treatment head is not connected, the level of the detection point P1 is high (the first resistor R1 is used as a pull-up resistor) or low (the first resistor R1 is used as a pull-down resistor); when the hand tool treatment head is connected to the host, the voltage value of the detection point P1 will change according to the circuit connection between the second pin PIN2 and the fourth pin PIN4 of the second connector. Taking the electronic component as the voltage divider resistor R2 as an example, when the first connector of the host and the second connector of the hand tool treatment head are connected, the voltage terminal VCC, the first resistor R1, the voltage divider resistor R2 and the ground GND constitute a voltage divider circuit, and the voltage value of the detection point P1 is the voltage divider voltage of the voltage value VCC. By using the first resistor R1 and the voltage divider resistor R2 with appropriate resistance values, the voltage value of the detection point P1 can be significantly changed when the first connector and the second connector are connected relative to when they are not connected. By configuring the MCU program to control the GPIO to read the voltage value of the first pin PIN1, that is, the detection point P1, the connection state of the hand tool treatment head can be determined.

[0051] It should be noted that the detection circuit provided in Example 1 and Example 2 of the present application realizes the connection status detection of the hand tool treatment head with a simple circuit structure. Those skilled in the art can understand that the electronic component connected between the second pin PIN2 and the fourth pin PIN4 of the second connector is not limited to a resistor, but can also be other electronic components. In principle, the simplest possible circuit is used to make the electrical characteristics such as the voltage value or the current value of the detection point P1 change significantly when the first connector and the second connector are connected relative to when they are not connected, so that the host of the laser medical device can identify the electrical change of the first pin PIN1, i.e., the detection point P1, through the input port.

[0052] The detection circuit of the hand tool treatment head of the third embodiment of the present application can be found in Figure 3 , different from Figure 1 In the detection circuit of the first embodiment shown, the first pin PIN1 of the first connector of this embodiment is grounded to GND through the third resistor R3, that is, the third resistor R3 acts as a pull-down resistor, and pulls the detection point P1 down to a low level when the hand tool is not connected to the host. In addition, in the detection circuit of the first embodiment, the connector pin is configured as a double pin, and in the detection circuit of this embodiment, the connector pin is configured as a single pin.

[0053] In specific implementation, the detection circuit of the hand tool treatment head of this embodiment includes: a first connector, a second connector and a third resistor R3.

[0054] The host of the laser medical device is configured with the first connector, the first connector is configured with a first pin PIN1, and the first pin PIN1 is grounded GND through the third resistor R3.

[0055] The hand tool treatment head is configured with the second connector, the second connector is configured with a second pin PIN2, and the second pin PIN2 is connected to the power supply terminal VCC.

[0056] When the first connector is connected to the second connector, the first pin PIN1 is connected to the second pin PIN2.

[0057] The host is configured with an input port, and the input port is connected to the first pin PIN1 and is used to read the electrical state of the first pin PIN1 to determine the connection state between the hand tool treatment head and the host.

[0058] Compare Figure 1 The embodiment 1 and Figure 3 The connection status of the hand tool treatment head is detected in the third embodiment shown: Figure 1 In the detection circuit, when not connected initially, due to the pull-up effect of the first resistor R1, the initial state of the detection point P1 is a high level; when the hand tool treatment head is connected to the host, the detection point P1 is grounded and the level state becomes a low level. Figure 3 In the detection circuit, when it is not connected initially, due to the pull-down effect of the third resistor R3, the initial state of the detection point P1 is a low level; when the hand tool treatment head is connected to the host, the detection point P1 is connected to the power supply terminal VCC, and the level state becomes a high level.

[0059] It should be noted that Figure 3The first pin PIN1 shown is connected to the ground GND through the third resistor R3 and the second pin PIN2 is connected to the power supply terminal VCC, wherein the first resistor R3 is used as a pull-down resistor to pull the detection point P1 down to a low level when the hand tool is not connected to the host. Those skilled in the art can understand that the third resistor R3 can also be used as a pull-up resistor to pull the detection point P1 to a high level when the hand tool is not connected to the host, that is, the first pin PIN1 is connected to the power supply terminal through the third resistor R3 and the second pin PIN2 is connected to the ground GND, then when the level of the detection point P1 is high, the hand tool treatment head is not connected; when the level of the detection point P1 is low, it is judged that the hand tool treatment head is in a connected state.

[0060] The detection circuit of the hand tool treatment head in the fourth embodiment of the present application can be found in Figure 4 , different from Figure 3 In the detection circuit of the third embodiment shown, the second pin PIN2 of the second connector of the hand tool treatment head of this embodiment is not directly connected to the power supply terminal VCC, but is connected to the power supply terminal VCC through an electronic component.

[0061] Based on the circuit analysis of the third embodiment, when the hand tool treatment head is not connected, the level of the detection point P1 is low; when the hand tool treatment head is connected to the host, the voltage value of the detection point P1 will change according to the circuit connection between the second pin PIN2 of the second connector and the power supply terminal VCC. Taking the electronic component as the voltage divider resistor R4 as an example, when the first connector of the host and the second connector of the hand tool treatment head are connected, the voltage terminal VCC, the third resistor R3, the voltage divider resistor R4 and the ground GND constitute a voltage divider circuit, and the voltage value of the detection point P1 is the voltage divider voltage of the voltage value VCC. By using the third resistor R3 and the voltage divider resistor R4 with appropriate resistance values, the voltage value of the detection point P1 can be significantly changed when the first connector and the second connector are connected relative to when they are not connected. By configuring the MCU program to control the GPIO to read the voltage value of the first pin PIN1, that is, the detection point P1, the connection state of the hand tool treatment head can be determined.

[0062] Those skilled in the art can understand that the electronic component connected between the second pin PIN2 of the second connector and the power supply terminal VCC is not limited to a resistor, but can also be other electronic components. In principle, the simplest possible circuit is used to make the electrical characteristics such as the voltage value or the current value of the detection point P1 change significantly when the first connector and the second connector are connected relative to when they are not connected, so that the host of the laser medical device can identify the electrical changes of the first pin PIN1, i.e., the detection point P1, through the input port.

[0063] In addition, corresponding to the third embodiment, if the third resistor R3 is used as a pull-up resistor to connect the first pin PIN1 and the power supply terminal VCC, the second pin PIN2 may not be directly connected to the ground GND, but may be connected to the ground GND through an electronic component.

[0064] Comparing Examples 1 and 2 with Examples 3 and 4: Examples 1 and 2 use the dual pins of the connector to identify the connection status of the hand tool treatment head, which can be detected when the connection is stable, and therefore has higher reliability; Examples 3 and 4 use the single pin of the connector to identify the connection status of the hand tool treatment head, which has a simpler structure.

[0065] The detection circuit of the hand tool treatment head in the fifth embodiment of the present application can be found in Figure 5 , different from Figure 1 In the detection circuit of the first embodiment shown, the hand tool treatment head is further configured with a storage medium for storing information of the hand tool treatment head; the first connector and the second connector are both configured with corresponding transmission pins for the host to read the information of the hand tool treatment head in the storage medium. Those skilled in the art can understand that in any of the detection circuits described in the previous embodiments, the hand tool treatment head can be configured with a storage medium storing information of the hand tool treatment head.

[0066] In this embodiment, the transmission pins of the first connector include a first data pin PIN5 and a first power pin PIN7, and the transmission pins of the second connector include a second data pin PIN6 and a second power pin PIN8.

[0067] The host of the laser medical device reads the information of the hand tool treatment head in the storage medium through the built-in microcontroller; the microcontroller is configured with a communication port, and the storage medium is configured with a communication port; the communication port of the microcontroller and the communication port of the storage medium establish a communication connection through the transmission pins of the first connector and the second connector.

[0068] The communication protocol adopted by the communication port of the microcontroller and the communication port of the storage medium may be, for example, a serial port communication protocol, an I2C (Inter-Integrated Circuit) communication protocol, a serial peripheral interface (SPI, Serial Peripheral Interface) communication protocol or a single bus communication protocol.

[0069] In this embodiment, the information of the hand tool treatment head mainly includes information such as the model and specifications of the hand tool treatment head. Figure 5 As shown, the hand therapy head integrates a storage medium for writing the specification information of the hand therapy head in advance. After the hand therapy head is connected to the host, the host MCU program is configured to establish communication with the hand therapy head, and the information in the hand therapy head is read for display in the human-computer interaction interface and the condition judgment within the system, thereby realizing the recognition of the specification information of the hand therapy head.

[0070] like Figure 5As shown, an MCU is configured in the host, and a GPIO peripheral is used to detect the level state, that is, to detect the connection state of the hand tool treatment head. Initially, a first resistor R1 is set, that is, the GPIO is initially at a high level. Secondly, a communication port is configured on the MCU side, and the specific communication protocol is consistent with the storage medium communication protocol. For example, a serial port, I2C, SPI, single bus, etc. can be used. A 4PIN connector is configured on the host side, and the first pin PIN1 is respectively led out as a hand tool connection state detection signal, the third pin PIN3 is grounded GND, the first data pin PIN5 is used as a data line, and the first power pin PIN 7 is used as a power line. The hand tool treatment head end is configured with a connector that is plugged into the connector on the host end, and the second pin PIN2 is short-circuited with the fourth pin PIN4. When the hand tool treatment head is connected, the first pin PIN1 is connected with the second pin PIN2, the third pin PIN3 is connected with the fourth pin PIN4, and the first pin PIN1, the second pin PIN2, the fourth pin PIN4 and the third pin are connected, that is, they are low level, then the MCU GPIO port reads the level of the detection point P1 as low level, and through program setting, it is identified as the hand tool treatment head connection. At the same time, the first data pin PIN5 of the first connector of the host is connected with the second data pin PIN6 of the hand tool treatment head, and the first power pin PIN7 is connected with the second power pin PIN8. The first power pin PIN7 and the second power pin PIN8 provide power for the storage medium of the hand tool treatment head, that is, the host MCU establishes a communication link with the storage medium of the hand tool treatment head, and the storage medium is pre-written with information such as the specifications of the hand tool treatment head. By configuring the host MCU program, the information in the storage medium of the hand tool treatment head can be read and written, thereby realizing the identification of the specification information of the hand tool treatment head.

Among them, the detection circuit of the hand tool treatment head can be any detection circuit of the above embodiments. For how to judge whether the hand tool treatment head is connected to the host of the laser medical device according to the actual circuit connection, reference can be made to the description of the above embodiments, which will not be repeated here.

[0073] Based on the description of the above embodiments, according to the circuit connection in actual implementation, the first signal can be a high-level signal, and correspondingly, the second signal is a low-level signal; or, the first signal can be a low-level signal, and correspondingly, the second signal is a high-level signal. In addition, the first signal and the second signal can also be electrical signals with significantly different electrical characteristics, such as electrical signals with significantly changed voltage values.

[0074] Please refer to the control method of the laser medical device in Example 7 of this application. Figure 7 , compared with the control method described in Example 6, the control method of the laser medical device in this embodiment also includes: configuring a storage medium for the hand tool treatment head, the storage medium is used to store information of the hand tool treatment head (Note: the storage medium can be pre-configured, in order to clearly indicate the control process, the steps of configuring the storage medium are not shown in the figure); the first connector and the second connector are both configured with corresponding transmission pins (for details, please refer to Example 5); when the host of the laser medical device determines that the hand tool treatment head is connected to the host, the information of the hand tool treatment head in the storage medium is read through the transmission pin.

[0075] Generally, the host of the laser medical device can read the information of the handpiece treatment head in the storage medium in real time or periodically through the built-in microcontroller. A more preferred solution is as follows: Figure 7 As shown, after the host of the laser medical device determines that the hand tool treatment head is connected to the host, it reads the information of the hand tool treatment head in the storage medium through the transmission pin.

[0076] This embodiment uses the connection status as the entry for reading the storage medium, that is, triggering the reading of the storage medium after detecting that the hand tool treatment head is connected to the host, which can avoid polling to read the content of the storage medium and excessive consumption of the life of the storage medium, thereby reducing the life of the reusable hand tool treatment head. In addition, matching preset parameters can be selected according to the specification information.

[0077] Furthermore, the control method of this embodiment may also include: when the host of the laser medical device determines that the hand tool treatment head is connected to the host, outputting the read information of the hand tool treatment head, and / or outputting prompt information that the hand tool treatment head is connected to the host. The way of outputting information may be to display information on an interactive interface. Specifically, when the host of the laser medical device determines that the hand tool treatment head is connected to the host, information is displayed through an interactive interface (such as a display screen). The displayed information may include information of the hand tool treatment head or prompt information that the hand tool treatment head is connected to the host; the displayed information may also include information of the hand tool treatment head and prompt information that the hand tool treatment head is connected to the host.

[0078] Please refer to the control method of the laser medical device in Example 8 of this application. Figure 8 , compared with the control method described in Example 7, the control method of the laser medical device in this embodiment also includes: when the host of the laser medical device determines that the hand tool treatment head is not connected to the host, it outputs a command to control the laser to remain off, and / or outputs a prompt message that the hand tool treatment head is not connected to the host.

[0079] In actual application, the MCU built into the host polls to detect the connection status of the hand therapy head (for details, please refer to Examples 1 to 5); if it is detected that the hand therapy head is connected, the MCU reads the contents of the storage medium, and displays the connection status and specification information of the hand therapy head on the interactive interface. It can also automatically match the corresponding treatment parameters according to the connected hand therapy head, and output a command to control the laser to remain on to allow the host to output the laser; if it is detected that the hand therapy head is not connected, a command to control the laser to remain off is output to prohibit the host from outputting the laser, and a prompt is displayed on the interactive interface that the hand therapy head is not connected.

[0080] In summary, the technical solution of this application has the following advantages:

[0081] In terms of identifying the connection status of the handpiece treatment head, a simple circuit design is used to improve the problem that the system cannot identify the connection status in the traditional mechanical anti-fool design, which may cause the handpiece to still output laser when it is not connected or not connected correctly, causing harm, and the use of Hall switches and other methods increases the system's additional overhead and has low reliability.

[0082] The connection status of the handpiece treatment head is displayed through the human-machine interactive interface, which, combined with the mechanical fool-proof design, makes the system more reliable and intelligent.

[0083] By integrating storage media in the hand therapy head, when the hand therapy head is connected, the specifications and models of the connected treatment head can be intuitively displayed on the interactive interface, and the system will select matching parameters based on the specifications and models, thereby preventing misuse of clinical indications and mismatch between treatment parameters and the hand therapy head, thereby improving system reliability and interactive friendliness.

[0084] The connection status of the hand tool treatment head is used as the reading and writing entry of the storage medium to avoid frequent periodic polling of the information of the storage medium, which leads to a reduction in the life of the reusable hand tool treatment head.
