Description

Technical Field

[0001] This invention relates to the field of ultrasonic scalpel technology, and in particular to an ultrasonic scalpel transfer control method and system. Background Technology

[0002] An ultrasonic scalpel (ultrasonic cutting and hemostasis scalpel) is a common surgical instrument. It is widely used in surgical procedures due to its advantages such as minimal trauma, low smoke production, and ability to promote blood clotting. An ultrasonic scalpel (system) consists of a main unit, an ultrasonic transducer, and an ultrasonic scalpel head. Its working principle involves the main unit generating a power source of a specific frequency to the ultrasonic transducer. The transducer then generates mechanical vibrations at that frequency, which in turn cause the ultrasonic scalpel head to vibrate mechanically. Because of the high frequency and small amplitude of these vibrations, it can cut small areas of human tissue.

[0003] Due to the poor compatibility between the existing ultrasonic scalpel (system) main unit, ultrasonic transducer, and ultrasonic scalpel head, an adapter is currently used to connect the ultrasonic scalpel main unit to the ultrasonic transducer and ultrasonic scalpel head. However, the adapters currently on the market are in a constantly discharging state when not connected to the ultrasonic main unit, resulting in rapid energy loss and making it difficult to achieve long-term standby use.

When the power supply in the receiving signal module is in internal power supply mode, the output terminal of the receiving signal module outputs a second supply voltage V2. The step-down voltage regulator circuit is used to reduce the voltage of the second supply voltage V2 output by the output terminal of the receiving signal module to obtain a third supply voltage V3, and to supply power to the connection identification module based on the third supply voltage V3.

[0041] In one exemplary embodiment, the signal transmitting module 310 includes a waveform generating submodule and a current limiting submodule. The waveform generating submodule is used to emit a detection signal, and the current limiting submodule is used to limit the current of the signal transmitting module to obtain the detection signal. By setting the current limiting submodule, the current in the signal transmitting module 310 can be kept within a reasonable range, preventing the components in the signal transmitting module 310 from burning out due to excessive current. The waveform generation submodule includes a first amplifier U1A, a first oscillation resistor R3, a second oscillation resistor R5, a third oscillation resistor R4, a fourth oscillation resistor R6, and a first oscillation capacitor C2.

[0042] In another exemplary embodiment, a detection signal is generated by a microcontroller. The square wave generating unit implemented in pure hardware in this embodiment has the advantages of lower power consumption and higher operational stability compared to a microcontroller, which can further increase the standby time of the ultrasonic scalpel adapter 2.

[0043] In one exemplary embodiment, the gear position recognition submodule includes a filtering clamping unit and a gear-separating unit. The filtering clamping unit filters the button signal to obtain a corrected gear position signal. The corrected gear position signal enters the gear-separating unit to separate the button gear position information. The filtering clamping unit can improve the stability of the corrected gear position signal and ensure the accuracy of the gear-separating unit in separating the button gear position information. At the same time, the filtering clamping unit can prevent the gear-separating unit from being falsely triggered when there is no button signal input.

[0044] In one exemplary embodiment, the filter clamping unit includes a first filter resistor R9, a first filter capacitor C3, a second filter resistor R10, and a second filter capacitor C4.

Utilizing the delay effect of the first filter capacitor C3 and the second filter capacitor C4, the key signal can be filtered into a corrected gear signal, preventing the key signal from being distorted during transmission and ensuring the correctness of the gear shifting unit in separating the key gear information.

Resistor R24 ​​is connected in parallel with resistor R23.

[0048] The principle of the gear position recognition submodule provided in this application is as follows: The detection signal emitted by the signal transmitting module 310 is a square wave signal. After rectification by the execution terminal 3, the detection signal returns a button signal with a half-wave square wave signal. In this embodiment, when the button position information carried in the returned button signal is high, the voltage value of the half-wave square wave signal is a first voltage value; when the button position information carried in the returned button signal is low, the voltage value of the half-wave square wave signal is a second voltage value. It should be noted that the execution terminal 3 is an ultrasonic scalpel and a transducer. The ultrasonic scalpel is connected to the ultrasonic scalpel adapter 2 through the transducer. The ultrasonic scalpel is equipped with a high-level button and a low-level button. When the high-level button on the ultrasonic scalpel is pressed, the button position information carried in the returned button signal is high; when the low-level button on the ultrasonic scalpel is pressed, the button position information carried in the returned button signal is low; when neither the high-level nor low-level button on the ultrasonic scalpel is pressed, the detection signal does not return a button signal after passing through the execution terminal 3. The ultrasonic scalpel adapter 2 also includes an identification chip 12. When the ultrasonic scalpel adapter 2 is connected to the ultrasonic host 1 and the power supply mode is internal, the receiving signal module is powered by the power battery to supply power to the identification chip 12 based on the connection test signal. The ultrasonic scalpel adapter 2 can communicate with the ultrasonic host 1 through the identification chip 12, transmitting the button position information to the ultrasonic host 1 so that the ultrasonic host 1 can control the ultrasonic scalpel to work according to the button action on the ultrasonic scalpel. When the execution end 3, the ultrasonic scalpel adapter 2, and the ultrasonic host 1 are connected, when the position identification submodule does not receive the button signal, due to the voltage division characteristics of the first filter resistor R9 and the second filter resistor R10, the voltage value between the first filter resistor R9 and the second filter resistor R10 is the anti-false trigger voltage value. The voltage value at the output end of the high-gear clamping subunit 6 is the preset first limit voltage, and the voltage value at the output end of the low-gear clamping subunit 8 is the preset second limit voltage. It is worth noting that the first voltage value > the preset first limit voltage > the anti-false trigger voltage value > the preset second limit voltage > the second voltage value. Therefore, when the gear position recognition submodule does not receive a button signal, the outputs of the second amplifier U2A and the third amplifier U2B both output a high level, and the low-gear transmission optocoupler U3 and the high-gear transmission optocoupler U2 are not conducting. When the button signal carries the button position information of a high gear, the button signal outputs a low level through the second amplifier U2A, the high-gear transmission optocoupler U2 conducts, the button signal outputs a high level through the third amplifier U2B, and the low-gear transmission optocoupler U3 is not conducting. When the button signal carries the button position information of a low gear, the button signal outputs a high level through the second amplifier U2A, the high-gear transmission optocoupler U2 is not conducting, the button signal outputs a low level through the third amplifier U2B, and the low-gear transmission optocoupler U3 conducts. The button position information is transmitted to the recognition chip 12 in this way, so that the recognition chip 12 transmits the button position information to the ultrasonic host 1, enabling the ultrasonic host 1 to control the ultrasonic scalpel based on the aforementioned button position information.

[0049] In another exemplary embodiment, a detection signal is generated by a microcontroller. Compared to a microcontroller, a square wave generator assembled via hardware circuitry has advantages such as lower power consumption and higher operational stability.

[0050] In one exemplary embodiment, the signal receiving module includes a switch control submodule 4, which includes a MOSFET, a delay resistor R2, and a delay capacitor C1. The gate of the MOSFET is connected in series with the delay capacitor C1 and then grounded. The first end of the delay resistor R2 is connected to the source of the MOSFET, which is connected to a power supply battery. The second end of the delay resistor is connected to the gate of the MOSFET. The gate of the MOSFET is connected to the collector of the phototransistor in the optocoupler U1. The emitter of the phototransistor in the optocoupler U1 is grounded. The drain of the MOSFET is the output terminal of the signal receiving module. A MOSFET is used as the switch here because it offers good sensitivity. Connecting the optocoupler U1 provides unidirectional signal transmission, achieves electrical isolation between the input and output terminals, making it difficult for the output signal to affect the input signal. The optocoupler U1 also offers advantages such as strong anti-interference capability, stable operation, no contacts, and long service life. A MOSFET is used as the switch here because it offers good sensitivity.

[0051] The principle of the power control management module provided in this application is as follows: When the ultrasonic adapter 2 is not connected to the ultrasonic host 1 and the execution terminal 3, the ultrasonic scalpel adapter 2 does not receive the connection test signal from the ultrasonic host 1, so the optocoupler fails to conduct. At this time, since the gate of the MOS transistor is connected to the power battery through the delay resistor R2, the gate of the MOS transistor is at a high potential. After the delay capacitor C1 is fully charged, it can ensure that the voltage at the gate of the MOS transistor is at a high potential, preventing the voltage change at the gate of the MOS transistor when the optocoupler is not conducting, which could cause the MOS transistor to conduct erroneously. When the ultrasonic scalpel adapter 2 is connected to the ultrasonic host 1 and the execution terminal 3, the light-emitting diode in the optocoupler will receive the connection test signal from the ultrasonic host 1. At this time, the light-emitting diode will conduct, thus turning on the optocoupler. Since the phototransistor in the optocoupler is grounded after the optocoupler is turned on, after the slow discharge of the delay capacitor C1, the voltage at the gate of the MOS transistor is pulled down, and the drain and source of the MOS transistor are connected. The power battery can then supply power to the signal transmission module 310 and the power control management module.

[0052] In summary, by setting up the adapter 2, the actuator 3 and the ultrasonic host 1 can communicate, expanding the adaptability of the ultrasonic host 1 to different actuators 3. Simultaneously, by determining whether it receives a connection test signal from the ultrasonic host 1, the adapter 2 can determine whether it is connected to both the ultrasonic host 1 and the actuator 3. This prevents excessive power consumption when the adapter 2 is not connected to the ultrasonic host 1 and the actuator 3, thus ensuring a longer standby time for the adapter and improving the applicability and user comfort of the ultrasonic scalpel.
