In the embodiment of the present application, at least two ultrasonic transducer devices are arranged on the surface of the master control chip, and the connection mode of the flexible conducting structure can expand the application range of the system and provide convenience for integrating more functional modules in the future. The embodiment of the present application has small overall volume and light weight, can adapt to complex interventional environment, and the signal conducting mode is convenient and flexible in operation. In addition, the required ultrasonic transducer device can be selected flexibly according to the needs.

[0034] Further, on the basis of the above-mentioned embodiments, the embodiment of the present application further provides another ultrasonic imaging system. In the embodiment of the present application, the number of ultrasonic transducer devices can be two, and correspondingly, the master control chip has enough interfaces (i.e. the first connecting part) to connect and drive each ultrasonic transducer.

Among them, Figure 3 The corresponding structural diagram for the stacked master control chips, the master control chips can be stacked in two layers, each layer of master control chips is connected with a plurality of corresponding ultrasonic transducer devices, and the backing layer is arranged between the two layers of master control chips. Or, the multiple master control chips can be stacked according to actual needs, and the backing layer supports each layer of master control chips. Or, the multiple master control chips can be stacked according to the needs, and form a three-dimensional structure to meet more use scenarios. Correspondingly, the backing layer is arranged between the multiple master control chips.

[0036] Further, the flexible conductive structure of the embodiment of the present application has multiple; the preset ultrasonic transducer device in the at least two ultrasonic transducer devices is close to the system interface module, and the other ultrasonic transducer device is close to the end of the sheath. Among them, when the multiple master control chips are spliced and connected, the second connecting part is arranged on the opposite two side edges of the package body of the master control chip. The preset flexible conductive structure (referring to Figure 2 , which is indicated as the second flexible conductive structure 23) is connected with the second connecting part corresponding to the ultrasonic transducer device close to the end of the sheath, and is arranged by bending around the edge of the package body of the master control chip, and the other end extends in the direction of the system interface module. The other flexible conductive structure (referring to Figure 2 , which is indicated as the first flexible conductive structure 22) is connected with the second connecting part corresponding to the ultrasonic transducer device close to the system interface module.

[0037] When the multiple master control chips are stacked, the second connecting part is arranged on the side of the package body of the master control chip close to the system interface module. The multiple flexible conductive structures are respectively connected with the second connecting parts of the corresponding master control chips, Figure 3Another structure diagram corresponding to the embodiment of the present application is shown, and the plurality of flexible conductive structures are distinguished as the first flexible conductive structure 22 and the second flexible conductive structure 23. Based on this, the signal of the ultrasonic transducer device can be led out to the second connection part at the side end by the master control chip, and the master control chip structure does not need to be changed even if the number of ultrasonic transducer devices increases. In an implementation manner, the second connection part can be welded by using a reflow soldering process.

Further, one end of the ultrasonic imaging catheter is provided with the second catheter connector; the second catheter connector is matched with the first catheter connector; and the ultrasonic imaging catheter is connected to the first catheter connector through the second catheter connector.

[0040] The embodiment of the present application is connected with the preset host computer through the system connector, and on the physical level, the socket of the system connector is directly connected with the socket of the host computer, playing a double role of electrical connection and mechanical fixation. The circuit can be placed in the system connector, realizing functions such as harmonic circuit, low-voltage power supply module, digital signal level conversion, storage of catheter ID, etc. The low-voltage power supply module is responsible for further voltage division and voltage stabilization of the low-voltage power supply provided by the ultrasonic host computer system. In actual use, due to different design requirements of the internal chip of the catheter, multiple different low-voltage power supplies may be needed. However, the host computer generally only provides 1 to 2 low-voltage power supplies, so multiple low-voltage power supplies need to be generated in the system connector. At the same time, in order to further compensate for the cable voltage drop caused by the cable, the low-voltage power supply module also provides a cable voltage drop compensation function. Further, the system connector and the ultrasonic imaging catheter are connected by using the matched two catheter connectors, and the two catheter connectors are docked to realize electrical and mechanical connection. Generally, an EEPROM is integrated into the catheter connector as a catheter identifier. According to the need, a digital circuit buffer can be arranged in the catheter connector to buffer the attenuation of the digital signal caused by the length of the cable.

[0041] The sheath assembly of the embodiment of the present application further comprises a steering structure 40 arranged at a preset position of the sheath, and a sheath component is integrated at an end of the sheath away from the steering structure. In the embodiment of the present application, the steering structure (such as a handle) is used to control the bending of the sheath, and the bending direction and degree of the distal end of the sheath can be conveniently controlled by the doctor during operation. In an embodiment, the steering structure comprises two rotating wheels to pull four traction ropes to realize the bending function of the sheath. In the steering structure, a knob and a bending knob can be arranged to allow the catheter to deflect left and right and rotate 360° to adapt to different surgical requirements. The sheath is used for entering a blood vessel and plays a role of mechanically connecting the steering structure and the distal end of the sheath (i.e. the sheath component), and also has a role of protecting internal electrical connection. Generally, the sheath wall is pulled by four traction guide wires to realize four-way bending of the distal end of the sheath.

[0042] In a specific implementation, the ultrasonic transducer device comprises a plurality of transducer elements arranged in a preset array to form a transducer array.

In a specific implementation, the master control chip is used for transmission, reception, and time delay control, and each transducer element corresponds to a transmission, reception, and time delay circuit to realize independent control of the transducer element.

[0043] In the embodiment of the present application, for each element in the transducer array, there is a set of high-voltage pulse generators, high-voltage switches, amplifiers, TGCs, and corresponding control circuits. In this way, it is ensured that a single element can be independently controlled by the ultrasonic host. Correspondingly, the control end of the control circuit corresponds to the first connection part, and the second connection part and the signal receiving and transmitting end of the master control chip correspond. The master control chip controls the transmission period, frequency, amplitude, time delay, etc. of each transducer element of the ultrasonic transducer device according to the control signal provided by the ultrasonic system host. When receiving ultrasonic waves, the return signals of a plurality of elements are amplified and delayed according to the time delay signal provided by the ultrasonic system host and are superimposed and transmitted to the system host channel. Specifically, Figure 5 、 Figure 6The schematic diagrams of the array element control circuit are shown respectively. As shown in the diagrams, the HV Pulser generates a high-voltage pulse signal for driving the ultrasonic transducer to emit ultrasonic waves, and the TR Switch is used for switching the transmission and reception modes. In the transmission mode, it transmits the high-voltage pulse signal to the ultrasonic transducer; in the reception mode, it transmits the weak signal received by the ultrasonic transducer to the subsequent circuit. The LNA is a low-noise amplifier used for amplifying the weak signal received by the transducer while maintaining a low noise level. The SH Delay is a sample-and-hold circuit used for sampling the signal at a specific time point and maintaining the value for a period of time for subsequent processing. The Σ is an analog addition used for adding the signals, and the SH Delay in front constitutes an analog time delay addition circuit. The Cable Driver is used for driving the signal transmission in the cable to ensure that the signal is not distorted during long-distance transmission. Further, the sheath component also includes a time gain compensation circuit used for adjusting the gain of the echo signal at different depths to compensate for the energy attenuation of the ultrasonic wave during propagation in the medium. Referring to Figure 6 , the time gain compensation circuit is arranged on the array element control circuit to perform TGC compensation amplification for each array element. Alternatively, referring to Figure 5 , the time gain compensation circuit is arranged on the connection channel of the master control chip and the system interface module to ensure that the received signal of each channel can be timely and accurately adjusted in gain, thereby improving the response speed and accuracy of the entire system.
