[0022] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] Debridement methods in related techniques often involve surgical debridement using mechanical scalpels and other electrosurgical instruments. However, surgical debridement is inefficient, its safety is difficult to guarantee, postoperative results cannot be assured, and it is prone to causing many complications. Furthermore, surgical debridement requires a high level of experience from the surgeon, and it can increase the risk of complications in elderly, frail, or critically ill patients. In addition, other debridement methods in related techniques include autolytic debridement and biological debridement. Autolytic debridement has a long debridement period, and the fluid generated during the autolytic process can easily soak the skin. Biological debridement is not suitable for patients with abnormal coagulation function.

[0024] Based on this, this application provides a wound cleaning device that can improve the efficiency of wound cleaning, enhance the safety of the cleaning process, and allow for adjustments to the cleaning method according to different situations.

[0025] Next, the debridement device provided in the embodiments of this application will be further described.

[0026] Please also refer to Figure 1 and Figure 2 , Figure 1 This illustration shows a schematic diagram of a debridement device provided in one embodiment of this application. Figure 2 A schematic diagram of the debridement device provided in one embodiment of this application is shown. Figure 1 and Figure 2 As shown, the debridement device 10 includes: a housing 101, a control switch 103, and a controller 111.

[0027] The controller 111 is located inside the housing 101 and is used to identify input signals and output corresponding control signals. In other words, the controller 111 serves as the control core of the debridement device 10, used to implement corresponding debridement functions based on input signals. Understandably, the controller 111 can be a microprocessor (MCU), programmable logic controller, or other similar device; this application does not limit the specific type of controller 111.

[0028] The housing 101 is equipped with a first interface 106, a second interface 107, and a power switch 108, all of which are connected to a controller 111. The first interface 106 is used to connect to the hydrodynamic knife 105, and the second interface 107 is used to connect to the plasma electrode 104. The controller 111 is used to control the operation of either the hydrodynamic knife 105 or the plasma electrode 104. The power switch 108 is used to power on and off the controller 111.

[0029] The control switch 103 is connected to the controller 111. The control switch 103 is used to send a gear position signal to the controller 111. The gear position signal includes a hydrodynamic knife gear position signal or a plasma electrode gear position signal.

[0030] Please see Figure 2 The wound cleaning device 10 also includes a power conversion circuit 102 and a motor 112. The power conversion circuit 102 is connected to the controller 111 and the motor 112, and is used to convert the external power supply 110 or the battery (…). Figure 2 The power input (not shown) supplies power to the controller 111 and the motor 112. The external power supply 110 can be a power distribution system or other power supply equipment for outputting electrical energy; this application does not limit the specific type of the external power supply 110. The wound cleaning device 10 can be connected via power line 110a (see [reference]). Figure 1 It is connected to an external power source 110. For example, the external power source 110 may be AC ​​power connected to the wound cleaning device 10.

[0031] In some embodiments, the power conversion circuit 102 includes a first conversion circuit 1021 and a second conversion circuit 1022. The input terminal of the first conversion circuit 1021 is connected to an external power source 110, and the output terminal of the first conversion circuit 1021 is connected to a controller 111. The first conversion circuit 1021 is used to convert the power input from the external power source 110 or a battery into AC power and output it to the controller 111. In some embodiments, when the external power source 110 is a power distribution system or power supply equipment for outputting AC power, the first conversion circuit 1021 can be a filter. In other embodiments, when the external power source 110 is a power distribution system or power supply equipment for outputting DC power, the first conversion circuit 1021 can also be a DC-to-AC circuit. This application does not limit the specific circuit structure of the first conversion circuit 1021. Thus, the first conversion circuit 1021 can meet the AC power requirements of the controller 111.

[0032] The input terminal of the second conversion circuit 1022 is connected to the output terminal of the first conversion circuit 1021, and the output terminal of the second conversion circuit 1022 is connected to the controller 111 and the motor 112. The second conversion circuit 1022 is used to convert the AC power output by the first conversion circuit 1021 into DC power. The second conversion circuit 1022 may include an AC-to-DC circuit, or it may include other chips or modules that implement AC-to-DC conversion. This application does not limit the specific implementation of the second conversion circuit 1022. In this way, the second conversion circuit 1022 can meet the DC power requirements of the controller 111 and the motor 112. In some embodiments, the debridement device 10 also includes a built-in battery (not shown in the figure), which is disposed inside the housing 101. The second conversion circuit 1022 also includes a bidirectional DC-DC conversion circuit (not shown in the figure). The bidirectional DC-DC conversion circuit is also connected to the built-in battery to power the built-in battery, or to obtain power from the built-in battery to power the controller 111 and / or the motor 112.

[0033] In this embodiment, the motor 112 is also connected to the controller 111, and the motor 112 is connected to the water-powered blade 105 through the first interface 106. The controller 111 controls the rotational speed of the motor 112 according to the water-powered blade gear signal, so that the motor 112 adjusts the flow rate of the water-powered blade 105. Understandably, in some embodiments, the debridement device 10 is also provided with a pump (not shown in the figure). The motor 112 controls the flow rate of the water output by the water-powered blade by driving one or more pumps. Thus, by controlling the rotational speed of the motor 112, the flow rate of the water-powered blade can be adjusted. In some embodiments, while adjusting the flow rate of the water-powered blade 105, the motor 112 also sends a feedback signal to the controller 111. The feedback signal may include the rotational speed information of the motor 112, and this application does not limit the specific content of the feedback signal. Understandably, in this application, the water-powered blade 105 cuts by ejecting a water jet through the blade head, and the cutting intensity of the water-powered blade 105 can be adjusted by adjusting the flow rate of the water jet.

[0034] Please refer to it again. Figure 2 The debridement device 10 also includes an electrode power conversion circuit 1041. The electrode power conversion circuit 1041 is connected to the controller 111 and is connected to the plasma electrode 104 via a second interface 107. The controller 111 controls the electrode power conversion circuit 1041 to output the corresponding power level to the plasma electrode 104 according to the plasma electrode level signal. Specifically, when the controller 111 receives the plasma electrode level signal sent by the control switch 103, the controller 111 sends a status judgment signal to the electrode power conversion circuit 1041. The electrode power conversion circuit 1041 confirms the required output level of the plasma electrode 104 based on the status judgment signal and outputs the corresponding power level. At this time, the energy field of the plasma electrode 104 increases or decreases due to the increase or decrease in received power, thereby realizing the level switching. In other embodiments, the plasma electrode 104 can also be a hand-controlled electrode that integrates the function of the control switch 103 into the electrode handle. The hand-controlled electrode directly communicates with the controller 111 to realize the level switching function. This application does not limit the specific method of switching the 104 levels of the plasma electrode.

[0035] Understandably, in this application, the plasma electrode 104 delivers radio frequency energy to its cutting head, and current flows between the cutting head and the loop electrode to form an energy field. When it is close to or in contact with the wound, radio frequency energy is delivered through a conductive liquid to achieve debridement or ablation cutting. The plasma electrode 104 and the hydrodynamic knife 105 involved in this application can be disposable devices or devices that can be sterilized and reused. This application does not limit the specific usage of the plasma electrode 104 and the hydrodynamic knife 105.

[0036] Please refer to the following: Figure 1and Figure 2 The working principle of the debridement device 10 will be explained below:

[0037] Specifically, when the water-powered blade 105 is connected to the first interface 106, the controller 111 detects a first signal at the first interface 106 to confirm that the water-powered blade 105 is connected to the first interface 106. Simultaneously, the controller 111 acquires a data packet from the first interface 106, which includes blade head identification information of the water-powered blade 105. This blade head identification information can be obtained by means of an angle sensor or a camera, capturing the blade head's positioning angle. The device acquiring the blade head identification information sends a data packet to the controller 111 through the first interface 106. The acquired positioning angle is compared with a preset angle to confirm the working status of the water-powered blade 105. If the blade head is correctly positioned, the water-powered blade 105 is used for wound cleaning; if the blade head is incorrectly positioned, the water-powered blade 105 is not used. This application does not limit the specific identification method of the water-powered blade 105's blade head. When the plasma electrode 104 is connected to the second interface 107, the controller 111 detects the second signal at the second interface 107 and confirms that the plasma electrode 104 is connected to the second interface 107. The plasma electrode 104 sends a data packet to the controller 111 through the second interface 107. The data packet includes the electrode type information of the plasma electrode 104.

[0038] In one embodiment of this application, the electrode type information emitted by the plasma electrode 104 can be obtained through the memory bus address embedded in the printed circuit board assembly (PCBA). Different addresses correspond to different levels and power. This application does not limit the specific method of electrode type identification. The plasma electrode 104 outputs electrode type information containing the address to the controller 111 through the second interface 107. The controller 111 obtains the corresponding memory bus address based on the received electrode type information, thereby identifying the electrode type of the current plasma electrode 104. In other embodiments, the electrode type information can be sent through wired communication connections such as Ethernet (ETH) or wireless communication connections such as Bluetooth or WIFI. This application does not limit the specific method of establishing communication signals.

[0039] The debridement device 10 has two operating modes: a first mode and a second mode. The first mode is the debridement mode, and the second mode is the plasma mode. When the controller 111 confirms that the water-powered knife 105 is correctly positioned based on the first signal, the debridement device 10 enters the first mode. When the controller 111 confirms that the plasma electrode 104 is connected to the debridement device 10 based on the second signal and obtains the electrode type information of the plasma electrode 104, the debridement device 10 enters the second mode.

[0040] Specifically, the first mode and the second mode can be switched. When in the first mode, if the hydrodynamic knife 105 cannot remove large wounds and soft tissues, the operation can be switched to the second mode and the plasma electrode 104 can be used. When in the second mode, if the plasma electrode 104 cannot aspirate waste liquid in time, the operation can be switched back to the first mode and the hydrodynamic knife 105 can be used.

[0041] Please see Figure 2 In some embodiments, the control switch 103 includes a foot switch 1031 and a push-button switch 1032. The foot switch 103 is connected to the controller 111 through a foot switch interface 109 provided on the housing 101. The foot switch 103 sends a gear position signal to the controller 111 by controlling the pedal, and the controller 111 outputs control information according to the received gear position signal.

[0042] In one embodiment of this application, the foot switch 103 can be a three-pedal switch. When in the first mode, the three pedals of the foot switch 103 respond to user operation by sending a hydro-knife gear signal to the controller 111. The three pedals correspond to the gear increase signal, start / stop control signal, and gear decrease signal in the hydro-knife gear signal, respectively. The first mode has a total of ten gears. When the foot switch 103 outputs a gear increase signal or a gear decrease signal, each time the corresponding pedal is pressed, the gear can be increased or decreased by one gear. The higher the gear, the faster the motor 112 rotates, and the stronger the debridement function of the hydro-knife 105.

[0043] In the second mode, the three pedals correspond to the ablation and cutting signal, the gear switching signal, and the coagulation and hemostasis signal in the plasma electrode gear signal, respectively. The second mode has a total of nine gears. When the gear switching signal is output through the foot switch 103, each press of the corresponding pedal can switch the gear once. The greater the output power of the controller 111 to the plasma electrode 104, the stronger the ablation and cutting function of the plasma electrode 104. The gear can be set to switch from high to low or from low to high. This application does not limit the specific setting method of the plasma electrode 104 gears.

[0044] Understandably, the push-button switch 1032 can be mounted on the housing 101 and connected to the controller 111, achieving a function similar to the foot switch 103, which will not be described in detail here. When it is inconvenient for the user to use either the push-button switch 1032 or the foot switch 103 for control, the user can choose to switch to the other control method. This improves the flexibility of controlling the wound cleaning device 10. In some embodiments, the push-button switch 1032 can be a button switch, a rotary switch, or a touch switch, etc., and this application does not limit the specific usage of the push-button switch 1032.

[0045] Please see Figure 1 In one embodiment of this application, the plasma electrode 104 can be an electrode 104b with a suction tube. The electrode 104b with a suction tube is connected to the motor 112 via a second interface 107. The motor 112 is also used to adjust the flow rate of the conductive liquid in the suction tube. In the second mode, the controller 111 controls the output power of the motor 112 according to the plasma electrode setting signal, thereby controlling the flow rate of the conductive liquid in the suction tube through the motor 112, so that the suction tube can be used for cleaning while the plasma electrode 104 is cutting.

[0046] In another embodiment of this application, the plasma electrode 104 may be an electrode 104a without an attraction conduit. This application does not limit the specific structure of the plasma electrode 104, and users can choose according to the actual application scenario.

[0047] In this embodiment, the wound cleaning device 10 also includes a display screen 115, which is connected to the controller 111 to enable human-computer interaction. The display screen 115 can be a screen mounted on the housing 101, an externally connected display, or a front-end device such as a computer wirelessly connected to the controller 111. This application does not limit the specific display method or connection method of the display screen 115. The controller 111 sends display signals to the display screen 115, which may include information such as the current working mode and gear setting. This application does not limit the specific display content. Through the display screen 115, the user can intuitively obtain the current settings and working mode information of the wound cleaning device 10, improving the efficiency of the user's wound cleaning process.

[0048] The wound cleaning device 10 also includes an electrical component 113 connected to the controller 111. The electrical component 113 includes a volume control button 1131 and a speaker 1132. The volume control button 1131 sends a volume control signal to the controller 111 in response to user operation, and the speaker 1132 outputs voice reminders under the control of the controller 111. This allows users to obtain adjustment information through sound during wound cleaning, reducing the frequency of looking up at the display screen 115, enabling users to focus more on the operation and improving the efficiency and safety of wound cleaning. When the wound cleaning device 10 is operating in different working modes, the user adjusts the volume control button 1131 to make the speaker 1132 output different audio frequencies, allowing the user to determine the current working mode. The volume control button 1131 can be a knob or a button, and this application does not limit the specific design of the volume control button 1131. The speaker 1132 outputs voice reminders under the control of the controller 111, announcing the current working status of the wound cleaning device 10 to the user.

[0049] The debridement device 10 also includes a heat dissipation component 114 connected to a controller 111. The controller 111 controls the operation of the heat dissipation component 114 to achieve the heat dissipation function. The heat dissipation component 114 can be a fan to achieve the heat dissipation function. In other embodiments, the heat dissipation component 114 can also be other devices capable of achieving the heat dissipation function. This application does not limit the specific style of the heat dissipation component 114.

[0050] In one embodiment of this application, the controller 111 can output voltages of different power to each electrical device through a series-parallel combination circuit to meet the needs of each device, such as 12V, 24V, or 60V. This application does not limit the voltage power output by the controller 111. The controller 111 performs multi-stage processing of electrical energy, boosting or bucking the voltage that cannot be directly input to each electrical device to obtain the required voltage. For example, if the DC voltage inside the controller 111 is 12V, after bucking, it provides 3.3V or 5V to the electrical device. This application does not limit the specific method of multi-stage processing. In other embodiments of this application, the controller 111 can also implement voltage conversion through other chips or modules. This application does not limit the specific method by which the controller 111 implements voltage conversion.

[0051] It should be noted that, for the sake of simplicity, the aforementioned method embodiments are described as a series of actions. However, those skilled in the art should understand that this application is not limited to the described order of actions, because according to this application, some steps may be performed in other orders or simultaneously.

[0052] The above embodiments are preferred embodiments of this application and are not intended to limit the scope of this application. Any modifications and improvements made by those skilled in the art to the technical solutions of this application without departing from the spirit of this application shall fall within the protection scope defined by the claims of this application.
