Description

Technical Field

[0001] This utility model relates to an ultrasonic composite cable, and more particularly to a multifunctional and convenient ultrasonic composite cable assembly. It belongs to the field of signal transmission cable technology. Background Technology

[0002] Ultrasound imaging technology, as one of the core tools of modern medical diagnosis and industrial inspection, is widely used in clinical medicine (such as obstetrics and gynecology, cardiology, and superficial organ examination), industrial non-destructive testing (such as weld inspection and material evaluation), and scientific research due to its non-invasive, real-time, and high-resolution characteristics. In this technical system, the ultrasonic composite cable assembly is the key transmission medium connecting the ultrasonic probe and the main unit, undertaking the task of high-fidelity transmission of multi-channel ultrasonic signals (including transmit drive signals and echo receive signals). Its performance directly affects the quality of ultrasound imaging, the portability of the equipment, and the reliability of operation.

[0003] However, as ultrasound technology develops towards multi-element, high-frequency, and multi-functional integration, traditional ultrasound cables are gradually revealing the following technical bottlenecks: 1. Low integration of multi-channel signals and complex cable structure. Modern ultrasonic probes (especially high-end matrix probes or phased array probes) typically contain dozens to hundreds of tiny array elements (such as 128 elements, 192 elements, or even more). Each element needs to be independently connected to a signal path to achieve precise ultrasonic transmission and echo reception. In traditional solutions, multi-channel signals are usually transmitted through multiple independent cables or bulky wire bundles, resulting in large overall cable diameters, poor flexibility, and significant electromagnetic interference (EMI) problems between multiple cables, affecting signal integrity. In addition, to meet multifunctional requirements (such as probe heating, status indication, mode switching, etc.), auxiliary lines (such as heating control lines, LED signal lines) and control lines (such as mode switching command lines) need to be integrated, further increasing the complexity of the cable structure, assembly difficulty, and failure risk.

[0004] 2. Insufficient anti-interference capability; signal quality is easily affected by the environment. Ultrasonic echo signals are typically low-voltage signals in the microvolt range, making them highly susceptible to external electromagnetic noise (such as radiation from internal circuitry of the main unit or interference from operating room equipment) or crosstalk within the cable itself. Traditional cables often employ single-layer shielding (such as simple aluminum foil wrapping) or unshielded structures, resulting in limited shielding effectiveness and difficulty in effectively suppressing common-mode and differential-mode interference. Furthermore, improper grounding design of the signal loop can easily introduce ground loop noise, leading to problems such as image artifacts and decreased signal-to-noise ratio.

[0005] 3. Poor flexibility and durability, making it difficult to adapt to complex operating scenarios. In clinical use, ultrasound probes require frequent bending and twisting. Traditional cables, due to their rigid internal structure (such as multiple independent coaxial cables bundled together) and lack of tensile strength design, often experience problems such as internal wire breakage and insulation damage, leading to signal interruption or performance degradation. In addition, some cable sheath materials have poor chemical resistance (e.g., are easily corroded by medical disinfectants) and insufficient abrasion resistance, further shortening their service life.

[0006] 4. Limited functionality, unable to meet the needs for intelligentization and expansion. Traditional ultrasound cables focus solely on the basic function of "signal transmission," lacking support for auxiliary functions (such as probe status indication, user interaction feedback, and environmental adaptability adjustment). For example, some probes require integrated heating functions to prevent condensation from affecting imaging, or LED indicators to display operating status, but traditional cables do not provide independent transmission channels for such auxiliary signals. Furthermore, with the development of intelligent probes (such as digital probes that support parameter configuration and wireless communication), higher demands are placed on the precise transmission of control signals (such as mode switching commands and probe identification information), which traditional cables struggle to meet.

[0007] 5. Limited by materials and processes, high-frequency signal transmission performance is restricted. Ultrasonic imaging frequencies are evolving from the traditional 3-10MHz to higher frequencies (such as 15-20MHz or even higher), which places stricter demands on the low dielectric constant and low dielectric loss characteristics of the signal transmission medium. Traditional cable insulation layers mostly use ordinary polyethylene or polyvinyl chloride, which have a high dielectric constant (approximately 2.2-3.0), leading to increased signal transmission delay and significant capacitance effects, thereby reducing imaging resolution and penetration depth. In addition, insufficient braiding density of the metal shielding layer or grounding design defects can also affect the shielding effect of high-frequency signals.

[0008] To address the aforementioned issues, existing technologies have proposed several improvement solutions. For example, some patents simplify the structure by integrating multiple signal lines into the same sheath (such as multi-core harness design), but fail to resolve crosstalk and electromagnetic interference issues. Some solutions use a metal braided shielding layer to improve anti-interference capabilities, but neglect the independent transmission requirements of auxiliary function signals. Other solutions improve flexibility by optimizing sheath materials (such as using TPU), but do not enhance durability from the overall structural level (such as tensile strength design and multi-layer shielding synergy). While these improvements alleviate some shortcomings to a certain extent, none have formed a systematic solution that synergistically optimizes "highly integrated transmission of multi-channel signals, anti-interference, flexibility, and functional expandability," making it difficult to meet the comprehensive requirements of high-end ultrasonic equipment for composite cables. Utility Model Content

[0009] This invention aims to solve the above-mentioned problems by providing a multifunctional and convenient ultrasonic composite cable assembly.

[0010] The technical solution of this utility model to solve the above problems is as follows: A multifunctional and convenient ultrasonic composite cable assembly, comprising: Multiple main signal lines are used to transmit electrical signals sent by the host to multiple array elements of the ultrasonic probe, as well as electrical signals converted from ultrasonic echo signals received by multiple array elements of the ultrasonic probe. At least one auxiliary line is used to transmit auxiliary function signals; At least one ground or control wire is used for signal loop grounding, shield grounding, or control signal transmission.

[0011] In the above-mentioned technical solution of this utility model, the main signal line, auxiliary line, and ground or control line are integrated into one component, realizing the centralized transmission of various types of signals (ultrasound imaging main signal, auxiliary function signal, control and grounding related signal), avoiding the cumbersome and inconvenient use of multiple independent cables, and improving the integration and ease of use of the cable assembly. The main signal line is responsible for the transmission of key signals in the ultrasound imaging process, including the excitation signal from the host to the probe and the signal after probe echo conversion, which is the basic guarantee for ultrasound imaging; the auxiliary line can provide additional functions such as equipment status indication and environmental adaptation; the ground or control line ensures the stability of signal transmission and the controllability of the equipment, together meeting the various needs of normal operation of ultrasound equipment.

[0012] As a preferred embodiment of the above technical solution, the auxiliary function signal is a signal used to realize non-control-type additional functions of the ultrasonic equipment, including at least one of the following: equipment status indication signal, environmental adaptability signal, user interaction auxiliary signal, and function extension signal.

[0013] In the above-mentioned technical solution of this utility model, by transmitting equipment status indication signals, users can intuitively understand the working status of the ultrasound equipment (such as power on, power off, fault, etc.); environmental adaptability signals (such as probe heating control signals) enable the probe to adapt to different working environments (such as low temperature environments) and ensure equipment performance; user interaction auxiliary signals (such as button backlight signals) improve the convenience of user operation and interactive experience; and function expansion signals provide the possibility of adding new functions to the equipment in the future, enhancing the expandability and applicability of the equipment.

[0014] As a preferred embodiment of the above technical solution, the control signal is a signal used to control the probe or host functional module, switch modes, configure parameters, or communicate with the system, including at least one of the following: working mode control command, system enable signal, probe identification and configuration signal, and interactive control signal.

[0015] In the above-described technical solution of this utility model, the working mode control command allows users to flexibly switch the probe's working mode according to different detection needs (such as B-mode, color Doppler ultrasound mode, etc.); the system enable signal can control the opening and closing of various functional modules of the device, optimizing the device's power consumption and performance; the probe identification and configuration signal helps the host quickly and accurately identify the probe model and parameters, and perform corresponding configurations, ensuring the device's compatibility and accuracy; the interactive control signal enables interaction between the user and the device, such as using buttons on the probe to perform functions such as freezing and measurement. These control signals enable the ultrasound equipment to be precisely adjusted and operated according to different usage scenarios and user needs, improving the equipment's intelligence and operational efficiency.

[0016] As a preferred embodiment of the above technical solution, the main signal line, auxiliary line, and ground line or control line are integrated into one unit to form a composite core; the composite core also includes a tension rope located at the center and a perfluoroolefin polymer outer wrapping tape that integrates the main signal line, auxiliary line, and ground line or control line into one unit.

[0017] In the above-described technical solution of this utility model, the tension rope is located at the center of the composite core, capable of withstanding the tensile force experienced by the cable during use, preventing damage to the cable due to external pulling, and improving the cable's mechanical strength and durability. Integrating the main signal line, auxiliary line, and ground or control line together, and wrapping them with a perfluoroolefin polymer outer layer, not only further improves the cable's integration but also provides insulation and isolation, reducing mutual interference between different types of signals and ensuring the stability of signal transmission. The composite core design makes the cable structure more compact, facilitating installation and use, while also reducing the overall size and weight of the cable.

[0018] As a preferred embodiment of the above technical solution, the ultrasonic composite cable assembly further includes a metal braided shielding layer and an outer sheath covering the composite core.

[0019] In the above-described technical solution of this utility model, the metal braided shielding layer can effectively shield external electromagnetic interference, preventing external electromagnetic noise (such as interference from other equipment in the operating room) from affecting the signal transmission within the composite core, thus improving the anti-interference capability and stability of signal transmission and ensuring the quality of ultrasound imaging. The outer sheath protects the internal composite core and shielding layer, preventing the cable from being subjected to external physical damage (such as friction, compression, collision, etc.), and extending the cable's service life.

[0020] As a preferred embodiment of the above technical solution, the main signal line includes a center conductor, a perfluoroolefin polymer insulating foam layer, a perfluoroolefin polymer inner wrapping tape, a coaxial shielding layer, and a coaxial sheath.

[0021] In the above-described technical solution of this invention, the central conductor is used to transmit electrical signals. The perfluoroolefin polymer insulating foam layer has excellent insulation properties and a low dielectric constant, which can reduce the capacitance effect and signal attenuation during signal transmission, ensuring signal integrity. The coaxial shielding layer can further shield external interference, protecting the internal signals from being affected. The coaxial sheath provides physical protection for the internal conductor, insulating layer, and shielding layer. This multi-layered structure design enables the main signal line to adapt to the transmission requirements of high-frequency signals in ultrasound imaging, improving the stability and accuracy of signal transmission, thereby ensuring the quality of ultrasound imaging.

[0022] As a preferred embodiment of the above technical solution, the main signal line includes a first main signal line arranged around the tension rope and a second main signal line arranged around the first main signal line.

[0023] In the above-described technical solution of this utility model, by arranging the first and second main signal lines around the tension rope, the internal space of the cable is rationally utilized, making the signal line layout more orderly and facilitating signal management and transmission. The two main signal lines can transmit different signals (such as signals from different array elements or different types of signals), increasing the signal transmission channels and capacity, improving the signal transmission capability of the cable assembly, and meeting the signal transmission requirements of multi-element ultrasonic probes.

[0024] As a preferred embodiment of the above technical solution, the center conductor of the first main signal line is an 8-core stranded conductor; the center conductor of the second main signal line is a 16-core stranded conductor.

[0025] In the above-described technical solution of this utility model, stranded conductors with different core counts can transmit different quantities and types of signals according to actual needs. The first main signal line with an 8-core stranded conductor can be used to transmit relatively few signals, while the second main signal line with a 16-core stranded conductor can transmit more signals, providing a more flexible signal transmission scheme for ultrasonic probes to adapt to the needs of probes of different sizes and functions.

[0026] As a preferred embodiment of the above technical solution, the diameter of a single core of the 16-core stranded conductor is ≤0.345mm; and the overall diameter of the multifunctional and portable ultrasonic composite cable assembly is ≤8.0mm.

[0027] In the above-described technical solution of this utility model, the smaller single-core diameter and overall diameter make the cable thinner, facilitating its use in limited spaces. For example, in minimally invasive surgeries or space-constrained testing scenarios, it allows for easier probe manipulation and cable placement. While ensuring signal transmission performance, reducing the cable diameter reduces material usage, lowers production costs, and also improves the cable's flexibility and portability.

[0028] As a preferred embodiment of the above technical solution, the outer sheath is a low-smoke, halogen-free, flame-retardant sheath, selected from one of polyolefin sheaths, polyolefin elastomer sheaths, thermoplastic polyurethane sheaths, and cross-linked polyethylene sheaths.

[0029] In the above-mentioned technical solution of this utility model, the low-smoke halogen-free flame-retardant sheath will not produce a large amount of smoke and toxic gases when encountering a fire, reducing the harm of fire to personnel and the environment, and improving the safety of use. It is particularly suitable for hospitals, laboratories and other places with high safety requirements. The selected polyolefin, polyolefin elastomer, thermoplastic polyurethane, cross-linked polyethylene and other materials have good flexibility, chemical resistance, abrasion resistance and weather resistance, and can adapt to different working environments (such as high temperature, low temperature, humidity, etc.), extending the service life of the cable.

[0030] In summary, this utility model has the following beneficial effects: 1. This utility model integrates multiple main signal lines used for transmitting main signals (including transmission drive signals and echo conversion electrical signals) between the host and the ultrasonic probe array elements, auxiliary lines for transmitting auxiliary function signals (such as equipment status indication, environmental adaptability adjustment, user interaction assistance and function expansion signals), and ground wires or control lines responsible for signal loop grounding, shielding grounding or control signal transmission (such as working mode control, system enable, probe identification configuration and interactive control signals) into one, forming a composite cable structure. This significantly improves the integration of signal transmission, avoids the cumbersome connection of multiple independent cables, simplifies the cable layout of ultrasonic equipment, and improves ease of use. 2. This utility model endows ultrasound equipment with more additional functions and control capabilities through auxiliary lines and control lines. The auxiliary function signals realize non-control-related additional functions such as equipment status indication, environmental adaptation adjustment, and user interaction assistance, improving the ease of use of the equipment and user experience; the control signals support precise control of probe or host functional modules, mode switching, parameter configuration, and system communication, enhancing the intelligence level and functional expandability of the equipment, and meeting the diverse needs of different ultrasound imaging scenarios; 3. The main signal line of this invention adopts a multi-layer structure design consisting of a center conductor, a perfluoroolefin polymer insulating foam layer, a perfluoroolefin polymer inner wrapping layer, a coaxial shielding layer, and a coaxial sheath. The perfluoroolefin polymer insulating foam layer and the inner wrapping layer have the characteristics of low dielectric constant and low dielectric loss, which can reduce the capacitance effect and signal attenuation during signal transmission. The coaxial shielding layer further enhances the anti-interference capability of the signal, ensuring high-fidelity transmission of high-frequency ultrasonic signals and providing a solid foundation for high-quality ultrasonic imaging. 4. The main signal line includes a first main signal line and a second main signal line arranged around the tension rope. The center conductor of the second main signal line is a 16-core stranded conductor (single core diameter ≤ 0.345 mm), which can provide more signal transmission channels, increase the capacity and flexibility of signal transmission, meet the needs of multi-element ultrasonic probes for a large number of signal transmissions, and help to realize more complex ultrasonic imaging functions. 5. By optimizing the conductor core diameter (single core diameter of 16-core stranded conductor ≤ 0.345mm) and the overall structural design, this utility model achieves a cable assembly diameter ≤ 8.0mm, realizing the miniaturization and thinning of the cable without reducing the transmission quality, improving the cable's flexibility and portability, and facilitating operation by medical personnel. 6. The outer sheath is made of low-smoke, halogen-free flame-retardant material, which will not produce large amounts of smoke or toxic gases in the event of a fire, effectively reducing the harm to personnel and the environment, and improving the safety of ultrasonic equipment during use. It is particularly suitable for hospitals, laboratories, and other places with high safety requirements. The selected outer sheath material has good flexibility, chemical resistance, abrasion resistance, and weather resistance, enabling it to adapt to different working environments, extending the cable's service life, and ensuring stable and reliable operation of the cable in various complex environments.

Detailed Implementation

[0032] The utility model will be further explained below with reference to the accompanying drawings.

[0033] This specific embodiment is merely an explanation of the present invention and is not intended to limit it. Any changes made by those skilled in the art after reading this specification, as long as they fall within the scope of the claims, will be protected by patent law.

[0034] like Figure 1 As shown, a multifunctional and convenient ultrasonic composite cable assembly is presented. This cable assembly adopts a composite structure of "multi-channel signal integration + multi-layer functional protection," and its core consists of the following parts: 1) Composite core: includes multiple main signal lines 1, three auxiliary lines 2, one control line 3, a tension rope located in the center 4, and a perfluoroolefin polymer outer wrapping tape 5.

[0035] 2) Metal braided shielding layer 6: is a tin-plated copper wire braided mesh, which is wrapped around the outside of the composite core.

[0036] 3) Outer sheath 7: Covers the outside of the metal braided shielding layer 6. Composite conductors are the core transmission units of cable assemblies, and their integrated design enables efficient integration of multiple types of signals.

[0037] like Figure 1 As shown, the main signal line is divided into the first main signal line 110 and the second main signal line 120.

[0038] The first main signal line 110 has 6 wires arranged around the tension rope 4; the center conductor is an 8-core stranded conductor (single core diameter = 0.345mm); it is used to transmit low-frequency control signals or main signals of a small number of array elements (such as the transmit / echo signals of an 8-element probe).

[0039] Nine second main signal lines 120 are arranged around the first main signal line 110. They are used to transmit high-frequency main signals (such as the fine imaging signals of a 16-element probe). The stranded structure enhances the flexibility of the conductor and prevents a single thick conductor from breaking when bent.

[0040] Auxiliary lines 2, three in total, are used to transmit auxiliary function signals, for example: Equipment status indication signals (such as LED indicator control signals for probe connection status); Environmental adaptability signals (such as the power supply signal for the probe heating film, used to prevent condensation in low-temperature environments); User interaction auxiliary signals (such as controller button backlight control signals); Functional extension signals (such as data transmission lines for external sensors).

[0041] Ground or control line 3: One line, serving a dual function: on one hand, it acts as the ground wire for the signal loop (ensuring the stability of signal transmission); on the other hand, it transmits control signals, for example: Operating mode control commands (such as digital signals for switching between B mode and color ultrasound mode); System enable signal (controls the on / off state of the transmitting circuit); Probe identification and configuration signal (transmits the probe's unique ID or parameter configuration information); Interactive control signals (such as freeze / measurement commands triggered by the user pressing the probe button).

[0042] Tension rope 4: Located at the geometric center of the composite core, it is made of high-strength aramid fiber material; its function is to withstand the mechanical stress generated when the cable is bent, twisted or stretched, to prevent the internal signal line from breaking due to external force, and to improve the overall durability of the cable.

[0043] 5. Perfluoroolefin polymer outer wrapping: FEP (fluorinated ethylene propylene) raw material tape is wrapped around the tension rope and the three core wires (main signal line, auxiliary line, and ground / control line). FEP material has a low dielectric constant, excellent insulation and high temperature resistance, which can isolate electromagnetic interference between signal lines and provide flexible protection for the internal structure. At the same time, it is compatible with the insulation material of the main signal line (perfluoroolefin polymer) to reduce interface loss in signal transmission.

[0044] like Figure 1 As shown, the composite wire core is sequentially covered with a metal braided shielding layer 6 and an outer sheath 7, forming double protection: Metal braided shielding layer 6: Tinned copper wire is spirally wound around the outside of the composite core at a braiding density (coverage) of 30-40%, with a total thickness of approximately 0.2-0.3 mm. Tinned copper wire has good conductivity and corrosion resistance, effectively shielding external electromagnetic interference (such as high-frequency electrosurgical units in operating rooms and radio frequency noise from MRI equipment), while guiding common-mode interference from internal signal lines to the ground (through the grounding wire), ensuring a signal-to-noise ratio ≥60dB for the transmission of ultrasonic echo signals (weak signals).

[0045] Outer sheath 7: Made of low-smoke halogen-free flame-retardant material, specifically thermoplastic polyurethane elastomer sheath with a thickness of 1.0mm.

[0046] Main signal line 1, as the core channel for ultrasonic signal transmission, is designed to balance high-frequency performance and signal integrity. Taking the second main signal line with a 16-core stranded conductor as an example... Figure 2 As shown, its structure is as follows: Center conductor 11: 16-core stranded conductor (single core diameter = 0.345 mm); Perfluoroolefin polymer insulating foam layer 12: A microporous structure is formed on the outside of the conductor through a physical foaming process. The material is FEP, which significantly reduces the capacitance effect of signal transmission (capacitance per unit length ≤58pF / m) and reduces the attenuation of high-frequency signals (10~20MHz).

[0047] Perfluoroolefin polymer inner layer wrapping tape 13: FEP film is wrapped around the outside of the insulating foam layer to further isolate the insulating layer from the subsequent shielding layer and prevent signal leakage caused by microscopic damage.

[0048] Coaxial shielding layer 14: It is composed of aluminum-plastic composite foil (aluminum foil thickness 20~30μm, overlap rate ≥20%) and tin-plated copper wire braided mesh, which can reflect external electromagnetic waves and absorb internal crosstalk signals.

[0049] Coaxial sleeve 15: Made of the same TPU material as the outer sleeve, it protects the internal structure from mechanical scratches.

[0050] Through the above design, the overall diameter of the cable assembly is ≤8.0mm, which is significantly smaller than that of competing cables (single core diameter 0.0365mm, overall diameter 8.5mm). At the same time, it supports parallel transmission of up to 192 independent signal channels, balancing miniaturization and high performance.

[0051] Specific application scenario examples Scenario 1: Connection of multi-element ultrasound probe In an ultrasound diagnostic instrument equipped with a 192-element phased array probe, the 15 main signal lines of this cable assembly are connected to the 192 elements respectively (through multiplexing or time-division control), the auxiliary lines transmit probe heating control signals (environmental adaptability function), and the control lines transmit mode switching commands (such as switching from B mode to elastic imaging mode). The metal braided shielding layer effectively suppresses high-frequency interference generated by the electrosurgical unit in the operating room, ensuring that the signal-to-noise ratio of the echo signal meets the requirements of high-definition imaging.

[0052] Scenario 2: Portable ultrasound equipment In field rescue or bedside ultrasound equipment, the low-smoke halogen-free outer sheath of the cable assembly is resistant to bumps and disinfectant corrosion, the tension rope prevents cable breakage caused by frequent probe movement, and the 8-core and 16-core main signal lines can flexibly adapt to probes of different sizes (such as linear array probes or convex array probes), realizing the convenience of "one cable for multiple uses".

[0053] This specific implementation achieves high integration, strong anti-interference, high flexibility, and multi-functional scalability of ultrasonic equipment signal transmission through integrated design of composite cores, synergistic optimization of multi-layer shielding and protection structures, and refined layering of main signal lines. It solves the technical bottlenecks of traditional cables and is suitable for high-end ultrasonic equipment in various scenarios such as medical diagnosis and industrial testing.
