Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an ultrasonic surgical instrument with a wireless transmission structure. Background Art

[0002] Ultrasonic cutting and hemostasis systems are widely used in surgical medical devices. They accurately cut and coagulate diseased tissues to stop bleeding based on specific device configurations and ultrasonic energy, thereby minimizing patient trauma and promoting rapid recovery after surgery. Ultrasonic cutting and hemostasis systems consist of an ultrasonic driver, a transducer, a blade, and a blade. The ultrasonic driver generates a driving signal of the current or voltage required by the target drive unit, which is input to the transducer to convert the driving signal into a mechanical signal. The blade and the blade cut and stop bleeding on the target biological tissue under the drive of the mechanical signal.

[0003] However, the common connection method between the transducer and the blade is to use metal pins for direct contact for power supply and communication. This connection method has certain defects and surgical risks. For example, during the use of the transducer, the blade rod or the transducer needs to be rotated to adjust the blade position. There will be multiple rotations of electrical contact in the middle, which will cause the pin and the circular conductor connected to the pin to rust or have poor contact. During use, the metal pin may contact the liquid and cause a short circuit. In addition, due to the excessive number of signals, many metal pins are required for connection, resulting in a complex device structure. Utility Model Content

[0044] Specifically, after the ultrasonic scalpel head 100 and the transducer handle 200 are installed, the first wireless module 310 and the second wireless module 320 are arranged relative to each other, so that a mutual inductor capable of sensing electric energy can be formed. The button may include a MIN button and a MAX button, and the user may send a small-gear target ultrasonic signal to the button circuit 140 through the MIN button, so that the button circuit 140 may output a small-gear excitation signal to the first wireless module 310.

The first processor U3 processes the excitation signal from the key circuit 140 and sends it to the receiving chip U1. The processed excitation signal is processed by the receiving chip U1 and transmitted to the second antenna board 321 by the first antenna board 311 through the mutual inductor. The excitation signal is processed by the transmitting chip U4 electrically connected to the second antenna board 321 and then transmitted to the ultrasound host 01.

[0046] Specifically, antenna coils can be provided on both the first antenna board 311 and the second antenna board 321, and power transmission and signal transmission are realized through the antenna. Among them, the transmitting end chip U4 outputs a transmission drive signal to the second antenna board 321 under the control of the ultrasound host to drive the second antenna board 321 to output a transmission signal (i.e., a power signal). After receiving the transmission signal, the first antenna board 131 can output a preset voltage or a preset current to the power supply IC U2, so that the power supply IC U2 performs voltage stabilization, amplitude variation, etc. on the received preset current or preset voltage and transmits it to the first processor U3, thereby realizing the power supply function of the first processor U3. In addition, the first antenna board 131 can also output a preset voltage or a preset current to the key circuit 140 after receiving the transmission signal to realize the power supply function. The key circuit 140 is electrically connected to the first processor U3, so that after the user sends the target ultrasonic signal to the key circuit 140 through the MIN key or the MAX key, the key circuit 140 can output the corresponding excitation signal to the first processor U3. The first processor U3 processes the excitation signal and sends it to the receiving chip U1, which is then processed by the receiving chip U1 and transmitted to the second antenna board 321 through the mutual inductor by the first antenna board 311, thereby realizing signal transmission.

The second wireless module 300 is electrically connected to the ultrasonic host 01 through the cable L0 inside the transducer, thereby achieving signal transmission between the second wireless module 300 and the ultrasonic host 01. A circular channel A2 can be set on one side of the non-metallic front shell 221 close to the ultrasonic knife head 100, so that the amplitude transformer 210 can pass through the circular channel A2, and the amplitude transformer 210 does not contact the circular channel. It can be understood that the center of the second antenna plate 321 has a circular channel A3, and the amplitude transformer 210 can pass through the circular channel, and the amplitude transformer 210 does not contact the circular channel A3.

[0057] Optional, reference Figure 2 or Figure 3 The ultrasonic scalpel head 100 further includes: a gripping portion 150; the gripping portion 150 is integrally formed with the housing 110 of the ultrasonic scalpel head 100, or the gripping portion 150 and the housing 110 of the ultrasonic scalpel head 100 are detachable.

The processed excitation signal, usage information and technical parameters are sent to the second Bluetooth antenna 231 through the first Bluetooth antenna 161. After the second Bluetooth antenna 231 receives the information, it is processed by the second chip U7 and then transmitted to the ultrasound host 01. After reading the excitation signal, usage information and technical parameters, the ultrasound host 01 rewrites the usage information.

[0061] In addition, after receiving the excitation signal, the second processor U6 also obtains the use information and technical parameters of the ultrasonic knife head 100 from the encryption chip 130, processes the use information and technical parameters, and transmits them to the second Bluetooth antenna 231 through the first Bluetooth antenna 161 together with the excitation signal. The second Bluetooth antenna 231 sends the received use information and technical parameters to the second chip U7 for processing, and then the second chip U7 sends them to the ultrasonic host 01, so that the ultrasonic host 01 rewrites the use information according to the current use information, technical parameters and excitation signal. The rewritten use information can be transmitted to the encryption chip 130 for storage through the transmission route (i.e., through the second chip U7, the second Bluetooth antenna 231, the first Bluetooth antenna 161, and the first chip U5 in sequence), replacing the original use information. Among them, the use information may include the number of uses.

[0062] Optionally, the second Bluetooth module 230 is disposed in the transducer handle 200, or disposed inside or outside the ultrasound host 01. The embodiment of the utility model is preferably configured to dispose the second Bluetooth module 230 inside or outside the ultrasound host 01. In this way, the space occupied by the transducer handle can be reduced.

[0063] Exemplarily, the first Bluetooth module 160 and the second Bluetooth module 230 may include a Bluetooth chip (i.e., the first chip U5 and the second chip U7), a crystal oscillator, a resistor and other electronic devices. The Bluetooth chip has multiple GPIO ports and hardware peripheral resources such as ADC, SPI, UART, and IIC. The key circuit signal is connected to the GPIO port of the Bluetooth chip, and the gear control signal is sent to the ultrasound host through the Bluetooth circuit 161. The types of the first Bluetooth antenna 161 and the second Bluetooth antenna 231 include but are not limited to ceramic antennas, PCB antennas, IPEX antennas, 2.4G rod antennas, etc. The battery module 170 may be a button battery, a lithium battery, a rechargeable battery, etc.

It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
