Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly, to a detection system for a cordless ultrasonic scalpel. Background Art

[0002] The principle of an ultrasonic scalpel is to use an ultrasonic transducer to generate vibrations. The emitted ultrasonic waves propagate along the longitudinal axis of the blade, generating amplitude-amplified vibrations along the blade axis. Finally, high-speed longitudinal mechanical motion is generated at the end of the blade tip. The mechanical vibrations at the end of the blade tip are very effective in cutting soft tissue, and the heat generated by the high-frequency ultrasonic vibrations can coagulate tissue and seal blood vessels. Because the blade tip can be passed through a cannula to easily reach the surgical site, this device is particularly suitable for minimally invasive surgeries such as endoscopic and laparoscopic surgeries.

[0003] Existing desktop ultrasonic scalpels are all composed of a main unit + handle + surgical instrument. When an abnormality occurs during use, a test rod can usually be connected to the handle to test whether the handle and main unit are faulty. After the handle and main unit are faulty, the blade head can be replaced to avoid wasting the disposable blade head. Existing cordless ultrasonic scalpels are mainly composed of a generator module, a transducer, a blade head and a battery. The blade head has integrated buttons and a waveguide rod. The battery powers the generator module, which includes a processor and an ultrasonic drive signal generator. When an abnormality is detected during surgery, it is necessary to replace the blade head or the generator module to troubleshoot the problem. This may waste a disposable blade head and at the same time, it is impossible to accurately determine the cause of the fault. Summary of the Invention

[0021] The detection system of the cordless ultrasonic scalpel provided by the present invention is explained and illustrated in detail below with reference to the accompanying drawings.

[0022] Figure 1 This is a schematic diagram of the structure of an existing cordless ultrasonic knife. Figure 1 As shown, the cordless ultrasonic scalpel consists of a generator module 11, a transducer 12, a blade head, and a battery 15. The blade head integrates a button 13 and a waveguide rod 14, which is connected to the transducer 12. The battery 15 powers the generator module. The generator module 11 includes a processor and an ultrasonic drive signal generator, and the button 13 is connected to the ultrasonic drive signal generator via a connector. The generator module 11 generates ultrasonic drive signals under the control of the button. The button includes a gear adjustment button and an excitation button. The ultrasonic drive signal generator is connected to the transducer 12. The blade head also includes an ID recognition chip and a buzzer. The ID recognition chip can use a one-line memory. In addition to the button signal, the communication between the generator module and the blade head may also include a blade head ID recognition signal and a buzzer signal. The interface between the generator module and the blade head also includes a data communication interface, such as a serial port. In the prior art, the generator module and transducer can be integrated. The generator module, transducer, and battery can also be integrated.

[0023] This embodiment specifically discloses a detection system for a cordless ultrasonic knife. Figure 2 As shown, it includes a power supply 1, a processor 2, a drive signal generator 3, a drive signal detection circuit 4 and a tool head interface 5. The power supply 1 is used to supply power to all circuits and devices in the detection system.

[0024] The blade head interface 5 is used to connect to the blade head of the cordless ultrasonic scalpel. The blade head interface 5 includes a test transducer and a signal connector. The test transducer is used to connect to the waveguide rod 14 of the cordless ultrasonic scalpel. The drive signal generator 3 is connected to the processor 2 and the test transducer respectively. The signal connector is used to connect the button 13, ID identification chip, and at least one of the buzzer of the cordless ultrasonic scalpel head and the processor 2.

[0025] The drive signal detection circuit 4 is used to detect the energy of the test transducer. The drive signal detection circuit 4 is electrically connected to the processor 2. The drive signal detection circuit 4 is connected to the test transducer of the blade head interface 5. The drive signal detection circuit 4 can detect the energy of the test transducer of the detection system. By detecting the energy of the test transducer, a fault of the waveguide rod can be determined. The processor 2 can determine whether the blade head button is normal by detecting the key signal transmitted by the signal connector. The processor 2 can determine whether the ID identification chip of the cordless ultrasonic knife is normal by detecting the signal of the ID identification chip transmitted by the signal connector. The processor 2 generates a buzzer drive signal, which is transmitted to the buzzer through the signal connector. The user determines whether the buzzer sound is normal. The drive signal detection circuit 4 can detect the amplitude, frequency signal, voltage, current, power and other information of the drive signal received by the test transducer, and determine whether the amplitude and frequency are within the set range, thereby detecting whether the blade head of the cordless ultrasonic knife is normal.

[0026] In some embodiments, the drive signal detection circuit 4 includes a voltage sensor and a current sensor. The voltage sensor is connected in parallel with the test transducer, and the current sensor is connected in series with the test transducer. Both the voltage sensor and the current sensor are electrically connected to the processor 2. The voltage sensor is used to detect the voltage of the test transducer and feed the voltage signal back to the processor 2. The current sensor is used to detect the current flowing through the test transducer and feed the current signal back to the processor 2. The processor 2 can determine whether the blade head of the cordless ultrasonic scalpel has a fault based on whether the actual voltage or current detected or the power calculated from the actual voltage and current detected is consistent with the set value.

[0027] In some embodiments, the detection system further includes a transducer interface 6, which is used to connect to the transducer 12 of the cordless ultrasonic scalpel. The transducer interface 6 is connected to the drive signal generator 3 and the processor 2 respectively. The drive signal detection circuit 4 is also used to detect the energy of the transducer of the cordless ultrasonic scalpel. The drive signal generator 3 outputs a drive signal of a certain amplitude, which is transmitted to the transducer 12 of the cordless ultrasonic scalpel via the transducer interface 6. The drive signal detection circuit 4 detects the energy of the transducer 12 connected to the transducer interface 6. If the energy and drive frequency of the transducer 12 of the cordless ultrasonic scalpel are within the range set by the detection system, the transducer 12 of the cordless ultrasonic scalpel is determined to be normal. Otherwise, the transducer of the cordless ultrasonic scalpel is determined to be faulty.

[0028] In some embodiments, the detection system also includes a generator module interface 7, which is used to connect to the generator module 11 of the cordless ultrasonic scalpel. The generator module interface 7 is electrically connected to the processor 2. The connection of the generator module interface 7 enables two-way communication between the generator module and the processor 2. Through the control and data analysis of the processor 2, the fault of the generator module of the cordless ultrasonic scalpel can be detected.

[0029] The data interfaces of the cutter head interface 5 , the transducer interface 6 and the generator module interface 7 of this embodiment adopt commonly used serial ports or one-line communication interfaces.

[0030] The detection system of this embodiment is connected and detected with the corresponding components of the cordless ultrasonic knife through the above-mentioned interface. The connection is convenient and the detection method is convenient. When a fault occurs, the cause of the fault can be accurately located, which facilitates rapid troubleshooting and avoids waste of components of the cordless ultrasonic knife.

[0031] In some embodiments, the detection system further includes a human-machine interface 8, which is electrically connected to the processor 2. The human-machine interface 8 is used to implement human-machine interaction and includes a display screen and control buttons, both of which are electrically connected to the processor 2. The display screen is used to display detection information, and the control buttons can be used to control the detection system's detection and can also serve as an excitation key and a gear adjustment key to control the output of the drive signal by the drive signal generator 3.

[0032] In some embodiments, the display screen is a touch screen display screen, and the detection system can be controlled by the touch screen display screen.

[0033] The human-machine interface 8 also includes an audio circuit for outputting prompt information or receiving user input commands. The audio circuit is electrically connected to the processor 2. The human-machine interface 8 may include a buzzer and a voice recognition device. When a fault is detected, the buzzer emits a voice output prompt information. The voice recognition device can recognize the user's command and transmit the recognition result to the processor 2, controlling the detection system to respond accordingly.

[0034] The detection system of this embodiment also includes a housing 9, within which a power supply 1, processor 2, drive signal generator 3, and drive signal detection circuit 4 are disposed. A blade interface 5, transducer interface 6, and generator module interface 7 are disposed outside of and detachably connected to the housing 9, and a human-machine interface 8 is embedded in the housing 9. The blade interface 5, transducer interface 6, and generator module interface 7 can be removed for separate sterilization, while other circuits and components within the housing 9 do not require sterilization, thereby extending their service life and ensuring detection accuracy.

[0035] The detection system of this embodiment also includes a battery interface and a voltage sensor. The battery interface is used to connect to the battery 15 of the cordless ultrasonic scalpel. The voltage sensor is electrically connected to the battery interface and processor 2. The battery is connected through the battery interface, the voltage sensor detects the battery voltage, and processor 2 determines whether the battery is faulty.

[0036] The power source 1 is a battery or an AC to DC power module. Preferably, the battery is a rechargeable battery, and the charging port is embedded in the housing 9.

[0037] The method for the detection system of this embodiment to detect faults of the cordless ultrasonic scalpel is as follows:

[0038] When detecting the generator module of the cordless ultrasonic scalpel, the generator module of the cordless ultrasonic scalpel is connected to the generator module interface 7, and the excitation start and gear adjustment are performed through the control buttons of the human-machine interface 8 or the touch display screen. The processor transmits the control signal to the generator module, and the generator module generates a drive signal. The drive signal is transmitted to the transducer connected to the generator module. The generator module returns the collected transducer energy parameters and the status parameters of the internal operation of the generator module (such as whether there is overvoltage, overcurrent, or overtemperature) to the processor 2. If the processor 2 determines that the actual power does not match the currently set gear or the generator module status is abnormal (the abnormal generator module status refers to abnormal voltage, abnormal current, or abnormal temperature), it is determined that the generator module of the cordless ultrasonic scalpel is faulty and displayed on the display screen.

[0039] When detecting the transducer of the cordless ultrasonic knife, the transducer of the cordless ultrasonic knife is connected to the transducer interface 6, and the excitation start and gear adjustment are performed through the control buttons of the human-machine interface 8 or the touch display screen. The processor sends the control signal to the drive signal generator 3, and the drive signal generator 3 outputs the drive signal to the transducer. The drive signal detection circuit 4 detects the actual power of the drive signal received by the transducer connected to the transducer interface 6 in real time, and returns the information to the processor 2. If the processor 2 determines that the actual power does not match the current gear, it is determined that the transducer of the cordless ultrasonic knife is faulty.

[0040] When testing the blade head of a cordless ultrasonic scalpel, connect the blade head to the blade head interface 5, the operator sets the gear through the gear adjustment button on the blade head, and then presses the excitation button of the blade head. If the processor 2 can detect the button, it indicates that the blade head excitation button and the gear adjustment button are normal (normal button means that the processor detects the pressing and pop-up signals of the excitation button and the gear adjustment button). After judging that the excitation button and the gear adjustment button are normal, the user presses the gear adjustment button to adjust to a gear, and then presses the excitation button. The processor 2 controls the drive signal generator 3 to output the drive signal, and the drive signal detection circuit 4 detects the actual power of the drive signal on the test transducer of the blade head interface 5. If it matches the current gear and the resonant frequency of the waveguide rod is within the error range allowed by the factory settings of the cordless ultrasonic scalpel, the waveguide rod is normal. Processor 2 directly reads the data stored in the ID identification chip, compares it with the pre-stored data content, and determines whether the data content is correct, so as to determine whether the cutter head is a cutter head of the specified model or manufacturer; Processor 2 sends a buzzer drive signal to the buzzer, and the user listens to whether the buzzer can sound normally, so as to determine whether the buzzer is normal.

[0041] When testing the battery of a cordless ultrasonic scalpel, the battery interface is connected to the battery of the cordless ultrasonic scalpel. The voltage sensor is electrically connected to the battery interface and processor 2 respectively. The voltage sensor detects the battery voltage and transmits the detected voltage value to the processor. Processor 2 determines whether the battery is faulty. If the voltage is too low or too high, it is considered a fault. The battery interface includes a communication interface connected to processor 2. Processor 2 reads the parameters of the battery's internal control chip and displays battery fault information or battery usage information.

[0042] The detection system of this embodiment can be connected to the generator module, blade head, transducer and battery separately to independently detect whether there is any fault in the generator module, blade head, transducer and battery; they do not interfere with each other and the detection is simple; and when a fault occurs, the cause of the fault can be accurately located, and fault detection is performed on each component of the ultrasonic scalpel, which facilitates rapid troubleshooting and reduces maintenance costs.
