Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic equipment, and in particular to an ultrasonic probe and a manufacturing method thereof, and an ultrasonic endoscope system. Background Art

[0002] Ultrasound endoscopic systems are currently widely used in the medical field. A typical ultrasound endoscopic system consists of a console, a robotic arm, and an interventional device fixed to the free end of the robotic arm. The ultrasound probe is inserted into the human body through the interventional device for examination. An ultrasound probe uses a piezoelectric chip to transmit and receive ultrasound waves, primarily utilizing the material's piezoelectric effect to convert electrical energy into acoustic energy. During endoscopic ultrasound examinations, the flexible tube at the front of the small ultrasound probe is inserted directly into the patient's upper gastrointestinal cavity. It features a compact size, ease of operation, and clear imaging. The ultrasound probe generates ultrasound waves toward the area being examined and receives the echo signals reflected from the area. Electrical signals corresponding to the received echo signals are output to the console. After various signal processing steps are performed in the console, the signals are displayed as ultrasonic tomographic images on a monitor. Because of the need for human intervention, the ultrasound probe has a unique structure and a complex manufacturing process. The ultrasound probe consists of an outer sheath enclosing a spring tube and ultrasonic transducer. During manufacturing, the spring tube is filled with a coupling agent to improve the transmission efficiency of the ultrasonic signal.

[0003] However, existing coupling agents are generally made of a mixture of solvents with multiple components. Due to the different solubilities of different solvents, bubbles may exist in the mixed coupling agent. Once the bubbles enter the spring tube, they cannot be discharged in time, which can easily affect the ultrasonic performance of the ultrasonic transducer and the image quality ultimately output by the ultrasonic probe.

[0004] Therefore, the existing technology still needs to be improved and developed. Summary of the Invention

[0033] In order to enable those skilled in the art to better understand the solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0034] See Figure 1 、 Figure 2 and Figure 3In one embodiment of the present invention, an ultrasound probe is disclosed for an ultrasound endoscope system, which includes a shell 10, an outer sheath tube 20, an ultrasonic component 30, a probe core shaft 40 and a spring tube 50. The shell 10 is formed with a cavity 11 and a docking channel 12 located on the side of the cavity 11; the outer sheath tube 20 is inserted into the docking channel 12; the ultrasonic component 30 is arranged in the inner cavity of the outer sheath tube 20, at the end of the outer sheath tube 20 away from the shell 10; the probe core shaft 40 is arranged in the cavity 11; the spring tube 50 is arranged in the inner cavity of the outer sheath tube 20, one end of which is connected to the ultrasonic component 30 and the other end of which is connected to the probe core shaft 40; a central channel 41 is formed on the probe core shaft 40 along the axial direction, and the central channel 41 is docked with the spring tube 50 for arranging a coaxial signal line 60; an exhaust hole 42 is formed on the probe core shaft 40 along the radial direction and communicates with the central channel 41.

[0035] During the manufacturing process of the ultrasonic probe disclosed in this embodiment, the probe core shaft 40 is docked with the spring tube 50, and an ultrasonic component 30, such as an ultrasonic transducer, is connected to the end of the spring tube 50 facing away from the probe core shaft 40. In addition, a coupling agent is injected into the spring tube 50 and the probe core shaft 40 to improve the transmission effect of the ultrasonic signal. During the injection of the coupling agent, the entire spring tube 50 and the probe core shaft 40 are immersed in the coupling agent, but the exhaust hole 42 on the probe core shaft 40 extends above the liquid surface, so that the bubbles inside the spring tube 50 can move along the axial direction into the central channel 41 and be discharged from the exhaust hole 42, thereby reducing the gas residue inside the spring tube 50 and the probe core shaft 40. Finally, the outer shell 10, outer sheath 20, etc. are assembled as a protective structure.

[0036] It can be seen that in this embodiment, by fully filling the coupling agent, the transmission medium inside the ultrasound probe is made uniform, which is conducive to more efficient transmission of ultrasound signals during operation, thereby improving the image quality output by the ultrasound probe.

[0037] Specifically, as one implementation of this embodiment, the vent 42 is disclosed as a threaded hole, which is used to assemble a sealing screw 70. During the manufacturing process of the ultrasound probe disclosed in this embodiment, after the coupling agent is injected into the spring tube 50, bubbles are discharged from the vent 42. A sealing screw 70 is then assembled to block the vent 42, thereby sealing the vent 42 and preventing leakage of the coupling agent. This facilitates the subsequent safe assembly of the housing 10 and the outer sheath 20 without affecting the normal use of the ultrasound probe. In addition, the threaded hole and screw assembly method provides better sealing than the socket and plug assembly method and is less prone to loosening, making it more suitable for use in ultrasound probes that require telescopic and rotational operation.

[0038] like Figure 2 and Figure 3 As shown, as another implementation of this embodiment, the housing 10 is disclosed to include a probe front cover 13, a locking nut 14 and at least two sealing rings 15, and the cavity 11 and the docking channel 12 are formed in the probe front cover 13; the locking nut 14 is arranged in the cavity 11 and is threadedly connected to the probe front cover 13; an extrusion portion 141 is formed on the side of the locking nut 14 facing the docking channel 12, and the extrusion portion 141 is used to abut against the inner surface of the outer sheath tube 20.

[0039] In this embodiment, the outer sheath tube 20 is inserted into the docking channel 12 of the probe front cover 13, but the plug-in assembly is not stable enough and the airtightness is insufficient. A locking nut 14 is provided to be screwed to the probe front cover 13. As the locking nut 14 is screwed into the cavity 11, the extrusion portion 141 continuously advances in the docking channel 12. The extrusion portion 141 can be set to be a trumpet shape, with the diameter increasing as it approaches the root; or the outer diameter of the extrusion portion 141 can be set to be larger than the inner diameter of the outer sheath tube 20. In short, the extrusion portion 141 is made to squeeze the outer sheath tube 20 while advancing, so that the outer wall of the outer sheath tube 20 is in close contact with the probe front cover 13, and the inner wall of the outer sheath tube 20 is in close contact with the extrusion portion 141, thereby reducing the assembly gap and increasing the friction, so that the outer sheath tube 20 can be stably maintained in a connected state with the probe front cover 13.

[0040] like Figure 3 As shown, a mounting groove 142 is formed on the side of the locking nut 14 facing away from the docking channel 12. The sealing ring 15 is disposed within the mounting groove 142. The outer side of the sealing ring 15 abuts the locking nut 14, while the inner side of the sealing ring 15 abuts the probe core shaft 40. In this embodiment, the provision of the sealing ring 15 maintains relative stability between the locking nut 14 and the probe core shaft 40, maintains good airtightness within the internal environment, and prevents leakage of the coupling agent.

[0041] Specifically, as another implementation of this embodiment, it is disclosed that the sealing ring 15 includes at least one of a perfluororubber sealing ring 15 and a high-temperature resistant rubber sealing ring 15. The sealing ring 15 disclosed in this embodiment rotates synchronously with the rotation of the probe core shaft 40, that is, it is used as a dynamic sealing ring 15, so it repeatedly generates friction with the locking nut 14 during operation. Therefore, two seals are provided in this embodiment to further improve the sealing performance and reduce the occurrence of reduced airtightness due to wear. Rubber sealing rings 15 such as perfluororubber and high-temperature resistant rubber have good chemical inertness, wear resistance and high-temperature resistance properties, so they can maintain dimensional stability during movement, are more suitable for the use environment in this embodiment, and are conducive to maintaining a good sealing effect inside the ultrasonic probe and extending the service life of the equipment.

[0042] Specifically, the sealing ring 15 in this embodiment can be made of perfluororubber material and mixed with 300°C high temperature resistant powder, such as silicone polymer powder, organic fluoropolymer powder, etc., to produce a sealing ring 15 with good comprehensive performance such as wear resistance, high temperature resistance, and long service life.

[0043] It should be noted that the present embodiment only cites the types of sealing rings 15, but the protection scope of the present invention is not limited thereto. As long as other types of sealing rings 15 can achieve the technical effects disclosed in this application, they should also be within the scope of protection of this application as equivalent replacements for the concept of the present invention.

[0044] For example Figure 1 、 Figure 2 and Figure 3 As shown in FIG. 1 , as another implementation of this embodiment, the housing 10 includes a probe rear cover 16 threadedly connected to the probe front cover 13. The ultrasound probe includes an integrated waterproof cap 80, one end of which is sleeved onto the probe front cover 13 and the other end of which is sleeved onto the probe rear cover 16. The rear end of the ultrasound probe disclosed in this embodiment is also connected to a signal adapter, a lever, a lever mounting base, and other structures, all of which are assembled with the probe rear cover 16. The probe rear cover 16 is assembled with the probe front cover 13 to form a closed cavity 11 to protect the probe core shaft 40.

[0045] Furthermore, because ultrasound probes are used in medical settings, which place high demands on the hygiene of the equipment, they require frequent disinfection and cleaning. To prevent disinfectant, steam, or water from entering the probe, waterproof caps are placed on the front and back ends of the probe to protect it. Furthermore, the integrated waterproof caps facilitate assembly and disassembly, as well as transportation, helping to reduce manufacturing costs.

[0046] like Figure 4 As shown, as another implementation of this embodiment, the integrated waterproof cap 80 includes a first assembly portion 81 that is interference-fit with the probe front cover 13, a second assembly portion 82 that is interference-fit with the probe rear cover 16, and an intermediate portion 83 connected to the first assembly portion 81 at one end and to the second assembly portion 82 at the other end; the intermediate portion 83 is provided with at least one first fixing hole 831. In this embodiment, the integrated waterproof cap 80 connects the probe front cover 13 and the probe rear cover 16 through an interference fit, which improves the tightness of the assembly, reduces the assembly gap, and reduces the probability of water seepage. The integrated waterproof cap 80 extends from the probe front cover 13 to the probe rear cover 16. The intermediate portion 83 serves as both a connecting portion and a fixing structure for assembly with a hook, a hanging rod, or other structure. By passing the fixing structure through the first fixing hole 831, the integrated waterproof cap 80 can be fixed, thereby fixing the ultrasound probe.

[0047] For example Figure 4 As shown, as another implementation of this embodiment, the integrated waterproof cap 80 is disclosed to include an extension portion 84, one end of which is connected to the second assembly portion 82, and the other end of which is provided with a second fixing hole 841. In this embodiment, the extension portion 84 is further provided on the integrated waterproof cap 80, and the integrated waterproof cap 80 can also be fixed by assembling the second fixing hole 841 with the fixing structure, thereby increasing the fixing method of the integrated waterproof cap 80 and making the use of the integrated waterproof cap 80 more flexible.

[0048] Specifically, the integrated waterproof cap 80 disclosed in this embodiment is a silicone waterproof cap. Silicone has a long service life, good waterproofness, and elasticity, and can play a buffering role to protect the probe front cover 13 and the probe rear cover 16.

[0049] like Figure 5 As shown, as another embodiment of the present application, a method for manufacturing an ultrasound probe is disclosed, which is used to manufacture any of the above-mentioned ultrasound probes, wherein the manufacturing method includes:

[0050] S100, providing a probe core shaft 40 and a spring tube 50;

[0051] S200, welding the probe core shaft 40 and the spring tube 50 to form a semi-finished product structure;

[0052] S300, immersing the semi-finished structure in a coupling agent, and filling the coupling agent into the inner cavity of the spring tube 50 and the central channel 41 of the probe core shaft 40 by vacuuming in a vacuum box;

[0053] S400, closing the exhaust hole 42 on the probe core shaft 40;

[0054] S500 , assembling the semi-finished structure with the outer sheath 20 and the housing 10 , and connecting the spring tube 50 to the ultrasonic component 30 .

[0055] In this embodiment, the ultrasonic probe is manufactured by first injecting a coupling agent, expelling bubbles, and then sealing the probe core shaft 40, so that the ultrasonic signal transmission medium inside the ultrasonic probe is uniform, which is beneficial to improving the signal transmission effect, improving the final imaging quality of the ultrasonic probe, and improving the imaging clarity.

[0056] Specifically, as an implementation of this embodiment, step S400 is disclosed to specifically include:

[0057] S401, filling thread glue into the exhaust hole 42;

[0058] S402 , installing a sealing screw 70 into the exhaust hole 42 .

[0059] In this embodiment, thread sealant is first filled and then the sealing screw 70 is installed. The thread sealant is used to fill the assembly gap between the vent hole 42 and the sealing screw 70, thereby improving the sealing effect of the vent hole 42 and effectively avoiding the problem of coupling agent leakage.

[0060] As another embodiment of the present application, an ultrasonic endoscope system is disclosed, which includes any of the ultrasonic probes described above.

[0061] In summary, the present application discloses an ultrasound probe for an ultrasound endoscope system, which includes an outer shell 10, an outer sheath tube 20, an ultrasonic component 30, a probe core shaft 40 and a spring tube 50. The outer shell 10 is formed with a cavity 11 and a docking channel 12 located on the side of the cavity 11; the outer sheath tube 20 is inserted into the docking channel 12; the ultrasonic component 30 is arranged in the inner cavity of the outer sheath tube 20, at the end of the outer sheath tube 20 away from the outer shell 10; the probe core shaft 40 is arranged in the cavity 11; the spring tube 50 is arranged in the inner cavity of the outer sheath tube 20, one end is connected to the ultrasonic component 30, and the other end is connected to the probe core shaft 40; a central channel 41 is formed on the probe core shaft 40 along the axial direction, and the central channel 41 is docked with the spring tube 50 for arranging the coaxial signal line 60; an exhaust hole 42 is formed on the probe core shaft 40 along the radial direction and connected to the central channel 41. The ultrasonic probe disclosed in this embodiment has fewer components, a simple structure, and is easy to assemble. During the manufacturing process, the probe core shaft 40 is docked with the spring tube 50, and an ultrasonic component 30, such as an ultrasonic transducer, is connected to the end of the spring tube 50 facing away from the probe core shaft 40. In addition, a coupling agent is injected into the spring tube 50 and the probe core shaft 40 to improve the transmission effect of the ultrasonic signal. During the coupling agent injection process, the entire spring tube 50 and the probe core shaft 40 are immersed in the coupling agent, but the exhaust hole 42 on the probe core shaft 40 extends above the liquid surface, allowing bubbles inside the spring tube 50 to move axially into the central channel 41 and be discharged from the exhaust hole 42, reducing the gas residue inside the spring tube 50 and the probe core shaft 40. Finally, the housing 10, outer sheath 20, etc. are assembled as a protective structure. It can be seen that in this embodiment, by fully filling the coupling agent, the transmission medium inside the ultrasonic probe is uniform, which is conducive to more efficient transmission of ultrasonic signals during operation, thereby improving the image quality output by the ultrasonic probe and increasing the shipping yield of the ultrasonic probe.

[0062] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0063] It should be noted that the present invention uses an ultrasonic probe used in an ultrasonic endoscope system as an example to introduce the specific structure and working principle of the present invention, but the application of the present invention is not limited to ultrasonic probes, and can also be applied to the production and use of other similar workpieces.

[0064] It should be understood that the present invention is not limited to the exact construction described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the present invention is limited only by the appended claims.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
