Description

Technical Field

[0001] This invention relates to the field of ultrasonic scalpel power supply, and particularly to a dual power supply system for surgical ultrasonic scalpels. Background Technology

[0002] In current medical procedures, surgical ultrasonic scalpels are typically powered by AC / 220V power. However, during surgery, there is a risk of sudden power outages due to external power grid failures or other unforeseen circumstances. In the event of a power outage, the surgery will be forced to stop, and the ultrasonic scalpel will cease operation. This not only severely impacts the normal progress of the surgery but may also pose a serious threat to the patient's life.

[0003] Furthermore, existing ultrasonic scalpel devices lack effective power backup mechanisms. In the event of a power outage, they cannot immediately switch to backup power, leading to complete device failure. While some uninterruptible power supplies (UPS) systems exist, they are often not specifically designed for medical surgical environments and may suffer from switching delays, insufficient battery life, or incompatibility with the power management logic of the ultrasonic scalpel device. For example, a conventional UPS may continue to supply power to the device after a main power outage, even if the ultrasonic scalpel device's power switch is off, resulting in unnecessary consumption of backup battery power and hindering energy conservation.

[0004] Therefore, there is an urgent need for a dual power supply solution that can seamlessly switch between different power sources, intelligently determine the operating status of the equipment, and ensure that the surgery can continue safely and continuously in the event of a sudden power outage. Summary of the Invention

[0005] The purpose of this invention is to provide a dual-power supply system for surgical ultrasonic scalpels, which solves the risks caused by power outages during surgery, and also provides energy-saving sleep mode when power is restored. The backup power supply will not malfunction and waste energy without the user turning on the power switch of the ultrasonic scalpel device.

[0006] The technical solution of this invention is: The surgical ultrasonic scalpel dual-power supply system includes: Power plug, connect to AC / 220V power supply; The power switch for the ultrasonic scalpel device is connected between the power plug and the ultrasonic scalpel device and is turned on manually. A battery charger that connects the power plug to the spare battery; The backup battery is charged by a battery charger. The inverter power supply is connected between the backup battery and the ultrasonic scalpel device to provide AC power to the ultrasonic scalpel device.

[0007] Preferably, after the battery charger detects that the power plug is powered on, it automatically charges the backup battery when the battery power is insufficient, and automatically disconnects the charging when the battery power is full.

[0008] Preferably, the power plug is also connected to an AC / 220V power supply / power outage detection circuit and an ultrasonic scalpel power switch detection circuit; the AC / 220V power supply / power outage detection circuit detects the status of the power plug in real time, and the ultrasonic scalpel power switch detection circuit detects whether the ultrasonic scalpel device is powered on. If it is not powered on, it sends a power-off signal to the inverter power supply; if it is powered on, it sends a power-on signal to the inverter power supply.

[0009] Preferably, the inverter power supply is also connected to a power bypass relay, which is connected between the power switch of the ultrasonic scalpel device and the ultrasonic scalpel device. When the power plug is connected and the power switch of the ultrasonic scalpel device is turned on, the inverter outputs a control signal to open the power bypass relay, and the ultrasonic scalpel device is powered by AC / 220V power and operates normally.

[0010] Preferably, when the AC / 220V power supply fails, the AC / 220V power supply / failure detection circuit detects the power failure status, and at the same time, the ultrasonic scalpel power switch detection circuit detects that the ultrasonic scalpel device power switch is in the on state. Then, the inverter power supply shuts off the bypass relay signal and automatically starts the inverter power supply to convert the DC12V power supply of the backup battery into AC / 220V power supply to power the ultrasonic scalpel device.

[0011] Preferably, when the ultrasonic scalpel is powered by the inverter, if the AC / 220V power supply is restored, the AC / 220V power supply / power failure detection circuit receives the power signal, and at the same time the ultrasonic scalpel power switch detection circuit is in the ON state, the inverter immediately shuts off the output and goes into sleep mode, and within half a cycle, the bypass relay is activated to connect the AC / 220V power supply, and the ultrasonic scalpel continues to work.

[0012] Preferably, the AC / 220V power supply / power failure detection circuit consists of an operational amplifier and external resistors and capacitors, which converts the AC / 220V voltage into a DC voltage that varies with AC / 220V, and provides the MCU of the inverter power supply with the power supply / power failure judgment.

[0013] Preferably, the ultrasonic scalpel power switch detection circuit uses a full-bridge rectifier to rectify the AC / 220V of the ultrasonic scalpel device power switch into DC voltage, which is then supplied to the MCU of the inverter power supply to determine whether the ultrasonic scalpel device power switch is open or closed.

[0014] The advantages of this invention are: The present invention relates to a dual-power supply system for ultrasonic scalpels. When powered by AC / 220V AC power, the ultrasonic scalpel operates normally and automatically charges the battery of the backup inverter power supply. When the AC / 220V AC power supply fails, the external power supply to the ultrasonic scalpel device is de-energized, and the backup inverter power supply automatically starts, converting the DC / 12V power from the battery into AC / 220V AC power to continue the use of the ultrasonic scalpel without affecting the surgical procedure. This system solves the problem of sudden power outages during ultrasonic scalpel surgery or power failure before surgery, ensuring normal operation of the equipment in unexpected situations.

Figure 2 This is a schematic diagram of the AC / 220V power supply / power failure detection circuit and the ultrasonic scalpel power switch detection circuit of the present invention. Detailed Implementation

[0016] The preferred embodiments of the dual-power supply system for surgical ultrasonic scalpels according to the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that the following description is exemplary and not intended to limit the scope of protection of the present invention.

[0017] like Figure 1 As shown, the dual-power supply system for surgical ultrasonic scalpels provided by the present invention includes: Power plug 1 connects to the AC / 220V mains power grid to provide power to the entire system under normal conditions; The ultrasonic scalpel device power switch 2 is connected between the power plug 1 and the ultrasonic scalpel device 3, and is a manually operated double-blade double-throw switch. Battery charger 4 is connected between the power plug and the spare battery 5; Backup battery 5 is a 12V lead-acid battery, which is charged by battery charger 4. The inverter power supply 6 is connected between the backup battery 5 and the ultrasonic scalpel device 3. It has a specification of DC12V / AC220V and provides AC power to the ultrasonic scalpel device 3. AC / 220V power supply / power failure detection circuit 7 detects the status of the power plug in real time and sends a signal to the inverter power supply 6; The ultrasonic scalpel power switch detection circuit 8 detects whether the ultrasonic scalpel device is powered on and sends a signal to the inverter power supply 6. The power bypass relay 9 is connected between the power switch 2 of the ultrasonic scalpel device and the ultrasonic scalpel device 3, and is controlled by the inverter power supply 6.

[0018] like Figure 2 As shown, the AC / 220V power supply / power failure detection circuit 7 consists of operational amplifier U1.1, external resistors R1-R6, R9, R10, capacitors C1-C3, and Zener diode D1. It converts the AC / 220V voltage into a DC voltage that varies with the AC / 220V voltage and sends it to the MCU of the inverter power supply. The MCU reads the AC / 220V voltage value in real time to determine whether the power supply is on or off.

[0019] The ultrasonic scalpel power switch detection circuit 8 uses a full-bridge rectifier composed of diodes D2, D3, D4, and D5 to rectify the AC / 220V at the ultrasonic scalpel power switch into DC voltage. Then, R7 and R8 divide the voltage and supply it to the MCU of the inverter power supply to determine whether the power switch is open or closed: if the MCU receives voltage, it is determined to be open; if the MCU does not receive voltage, it is determined to be closed.

[0020] System operating logic.

[0021] 1. First, the power plug 1 is connected to the AC / 220V power supply. After the battery charger 4 detects that the power plug 1 is powered on, the backup battery 5 will automatically charge when the power is low and automatically disconnect from charging when the battery is fully charged.

[0022] 2. The AC / 220V power supply / power failure detection circuit 7 detects the status of the power plug 1 in real time, and at the same time works with the ultrasonic scalpel power switch detection circuit 8 to detect whether the ultrasonic scalpel device is powered on. If it is not powered on, it sends a power-off signal to the inverter power supply 6; if it is powered on, it sends a power-on signal to the inverter power supply 6.

[0023] 3. When the power plug 1 is connected and the power switch 2 of the ultrasonic scalpel device is turned on, the inverter power supply 6 outputs a control signal to turn on the power bypass relay 9, and the ultrasonic scalpel device 3 is powered by AC / 220V power and operates normally.

[0024] 4. When the AC / 220V power supply fails, the AC / 220V power supply / failure detection circuit 7 detects the power failure status. At the same time, the ultrasonic scalpel power switch detection circuit 8 detects that the ultrasonic scalpel device power switch 2 is in the on state. The inverter power supply 6 then shuts off the bypass relay signal and automatically starts the inverter power supply 6 to convert the DC12V power of the backup battery 5 into AC / 220V power to supply power to the ultrasonic scalpel device 3. The ultrasonic scalpel device 3 will not stop working due to the power failure.

[0025] 5. When the ultrasonic scalpel is powered by the inverter power supply 6, if the AC / 220V power supply is restored, the AC / 220V power supply / power failure detection circuit 7 receives the power signal, and at the same time the ultrasonic scalpel power switch detection circuit 8 is in the ON state. At this time, the inverter power supply 6 immediately shuts off the output and goes into sleep mode. Within half a cycle (about 10ms), the bypass relay is activated to connect the AC / 220V power supply, and the ultrasonic scalpel continues to work, achieving the characteristics of uninterrupted power supply and energy saving.

[0026] The present invention relates to a dual-power supply system for ultrasonic scalpels. When powered by AC / 220V AC power, the ultrasonic scalpel operates normally and automatically charges the battery of the backup inverter power supply. When the AC / 220V AC power supply fails, the external power supply to the ultrasonic scalpel device is de-energized, and the backup inverter power supply automatically starts, converting the DC / 12V power from the battery into AC / 220V AC power to continue the use of the ultrasonic scalpel without affecting the surgical procedure. This system solves the problem of sudden power outages during ultrasonic scalpel surgery or power failure before surgery, ensuring normal operation of the equipment in unexpected situations.

[0027] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All modifications made according to the spirit and essence of the main technical solution of the present invention should be covered within the scope of protection of the present invention.
