Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular to an ultrasonic electrosurgical unit with dual outputs. Background Art

[0002] At present, ultrasonic scalpels are the main electrosurgical medical devices. The ultrasonic scalpel converts ultrasonic electrical signals into ultrasonic mechanical vibrations through ultrasonic transducers, and then amplifies them through ultrasonic amplitude transformers, so that ultrasonic mechanical vibrations with a certain amplitude are output at the blade head. The end of the ultrasonic blade head vibrates at a certain frequency, and the liquid in the tissue cells in contact with the ultrasonic blade head vaporizes, causing the protein hydrogen bonds to break, the cells to disintegrate and re-fuse, and the tissue to coagulate and then be cut; when cutting blood vessels, the ultrasonic blade head contacts tissue proteins, and generates heat through mechanical vibrations, which causes the collagen structure in the tissue to be destroyed, causing protein coagulation, and then sealing the blood vessels to achieve the purpose of hemostasis.

[0003] Closing / cutting high-frequency electrosurgery generally includes monopolar or bipolar high-frequency electrosurgery. Monopolar electrosurgery has the functions of pure cutting, mixed cutting, monopolar coagulation, and electrocautery, while bipolar electrosurgery mainly has the function of coagulation. Bipolar coagulation is to provide high-frequency electrical energy to the body tissue through the two tips of the bipolar forceps, so that the blood vessels between the two ends of the bipolar forceps are dehydrated and coagulated to achieve the purpose of hemostasis. Bipolar coagulation is mostly used in more delicate operations such as brain surgery, microsurgery, ENT, obstetrics and gynecology, and hand surgery.

[0004] With respect to the above-mentioned related technologies, the inventors have found that the current ultrasonic scalpel is prone to bleeding when cutting certain vascular-rich tissues. Doctors need to use high-frequency electric scalpels to stop bleeding during surgery. Therefore, an ultrasonic scalpel host and an electric scalpel host are required during the surgery, which are connected to the ultrasonic scalpel and the electric scalpel respectively, occupying the working space.

[0024] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0025] The present application embodiment discloses an ultrasonic electrosurgical unit with dual outputs. Figure 1 , Figure 2 An ultrasonic electrosurgical knife dual-output surgical device includes a host 1, an ultrasonic scalpel 2 and an electrosurgical knife 3. The host 1 is provided with a power module 4, a controller 51, an ultrasonic driving circuit 52 and an electrosurgical knife driving circuit 53. The power module 4 is used to power the controller 51, the ultrasonic driving circuit 52 and the electrosurgical knife driving circuit 53. The controller 51 is electrically connected to the ultrasonic scalpel 2 through the ultrasonic driving circuit 52, and the controller 51 is electrically connected to the electrosurgical knife 3 through the electrosurgical knife driving circuit 53.

[0026] A detection module and a prompt module are provided in the host 1, and both the detection module and the prompt module are connected to the controller 51. The detection module is used to detect the voltage and current in the circuit between the ultrasonic drive circuit 52 and the ultrasonic knife 2 and the voltage and current in the circuit between the electric knife drive circuit 53 and the electric knife 3 and output a detection signal. The controller 51 is used to receive the detection signal and control the prompt module to prompt the surgeon the output of the ultrasonic knife 2 and the electric knife 3, wherein the detection module includes a first voltage and current feedback circuit 61 and a second voltage and current feedback circuit 62. The first voltage and current feedback circuit 61 and the second voltage and current feedback circuit 62 can use voltage and current sensors.

Both voltage and current feedback circuits 62 are connected to the controller 51. The first voltage and current feedback circuit 61 is used to detect the voltage and current in the circuit between the ultrasonic drive circuit 52 and the ultrasonic knife 2 and output a first detection signal. The second voltage and current feedback circuit 62 is used to detect the voltage and current in the circuit between the electrosurgical knife drive circuit 53 and the electrosurgical knife 3 and output a second detection signal. The controller 51 is used to calculate the voltage value and the current value after receiving the first detection signal and the second detection signal. The controller controls the prompt module to display the voltage value and the current value in the circuit between the ultrasonic drive circuit and the ultrasonic knife and the voltage value and the current value in the circuit between the electrosurgical knife drive circuit and the electrosurgical knife according to the size of the voltage value and the current value.

[0027] The prompt module includes a voice prompt module 63 and a display screen 64, both of which are connected to the controller 51. The controller 51 is used to receive the first detection signal and the second detection signal and calculate the current value and the voltage value of the two circuits. When the current value in the circuit between the ultrasonic drive circuit and the ultrasonic knife is greater than the first preset value or the current value in the circuit between the electroscalpel drive circuit and the electroscalpel is greater than the second preset value, the voice prompt module 63 is controlled to emit a preset voice and the display screen 64 is controlled to display preset text to prompt that the ultrasonic knife 2 or the electroscalpel 3 is started. The first preset value and the second preset value are pre-entered by the designer, indicating the current when the ultrasonic knife 2 or the electroscalpel 3 is working. The preset voice and preset text can be entered in advance by the user. In addition, the display screen can also display the voltage value and current value in the circuit between the ultrasonic drive circuit and the ultrasonic knife, as well as the voltage value and current value in the circuit between the electroscalpel drive circuit and the electroscalpel.

[0028] In addition, the host 1 is connected to two foot switches, which are used to turn on and off the ultrasonic knife 2 or the electric knife 3 respectively. A foot signal is generated when the foot switch is pressed. In addition, a handle signal is generated when the ultrasonic knife 2 or the electric knife 3 is started. A control panel 67, two first alarm lights 65 and two second alarm lights 66 are installed on the front of the host 1. The two first alarm lights 65 correspond to the handle signal of the ultrasonic knife 2 and the handle signal of the electric knife 3 respectively, and the two second alarm lights 66 correspond to the foot signals of the two foot switches respectively. The controller 51 is connected to the first alarm light 65 and the second alarm light 66. The controller is used to receive the handle signal to control the first alarm light 65 to light up to indicate the handle signal; and receive the foot signal to control the second alarm light 66 to light up to indicate the foot signal.

The electric knife drive circuit 53 includes a second processor and a high-frequency pulse signal generator. The input end of the second processor is connected to the controller 51, the output end of the second processor is connected to the high-frequency pulse signal generator, and the high-frequency pulse signal generator is electrically connected to the electric knife 3.

[0030] The control panel 67 is used to output a control signal according to the user's operation. The control signal is divided into a first control signal and a second control signal. The first control signal and the second control signal are used to drive the ultrasonic knife 2 and the electric knife 3 respectively. After receiving the first control signal, the controller 51 sends a signal to the first processor. The first processor controls the generator module to drive the transducer to drive the ultrasonic knife 2 according to the signal; after receiving the second control signal, the controller 51 sends a signal to the second processor. The second processor drives the high-frequency pulse signal generator to drive the electric knife 3 according to the signal. In this way, the controller 51 controls the ultrasonic drive circuit 52 to drive the ultrasonic knife 2 or the electric knife drive circuit 53 to drive the electric knife 3 according to the control signal.
