Description

Technical Field

[0001] The utility model relates to the technical field of medical detection equipment, in particular to an ultrasonic probe for an endoscope. Background Art

[0002] The ultrasound probe is a key component of ultrasonic diagnostic imaging equipment. Its operating principle is to utilize the piezoelectric effect to convert the ultrasound machine's excitation electrical pulse signal into an ultrasonic signal that enters the patient's body. The ultrasonic echo signal reflected by the tissue is then converted into an electrical signal, thereby enabling tissue detection. Endoscopic ultrasound (EUS) is an examination method that uses endoscope guidance to perform ultrasonic scanning of the digestive tract wall and surrounding organs within the digestive tract. Endoscopic ultrasound combines endoscopy and intracavitary ultrasound technology, allowing not only the observation of mucosal lesions within the digestive tract lumen, but also real-time ultrasound scanning to observe lesions in the various layers of the digestive tract wall and surrounding tissues and organs. This is highly valuable for locating and characterizing lesions and plays an increasingly important role in the diagnosis and treatment of digestive system diseases.

[0003] When used in conjunction with an endoscope for intraluminal examination of the digestive tract, existing ultrasound probes are prone to slipping or deviating from the target area during operation, resulting in reduced stability and affecting imaging quality. Utility Model Content

[0032] Example 1

[0033] This embodiment provides a miniaturized single-element circular scanning ultrasound probe with a rotary drive device located at the front end of the probe. The probe has a capsule shape and can be swallowed directly into the upper digestive tract. A prismatic or columnar protrusion structure is provided at the rear end of the ultrasound probe to facilitate clamping and fixing with biopsy forceps or other tools. The posture and orientation of the probe in the stomach can be controlled by a gastroscope to achieve ultrasound examination. The probe has low cost and is flexible to use. It provides a more effective and convenient means for diagnosing gastric-related ultrasound examination indications, thereby promoting the development of endoscopic minimally invasive surgical treatment in primary hospitals.

[0034] This embodiment provides an ultrasonic probe for endoscope, comprising: an ultrasonic probe body 1 and a clamping fixture 2 arranged on the ultrasonic probe body 1 for easy clamping; the clamping fixture 2 is provided with a plurality of clamping parts 5 that are connected as one body or separated; each clamping part 5 is provided with at least two clamping surfaces 6, and at least one clamping surface 6 of each clamping part 5 is provided with an anti-slip structure 7.

[0035] The ultrasound probe provided in this embodiment is composed of an ultrasound probe body 1 and a carefully configured clamping fixture 2 at its tail. This allows for easy clamping and fixing with biopsy forceps or other tools, and for ultrasound examination to be performed by controlling the probe's position in the stomach through a gastroscope. In actual applications, the clamping fixture 2 can also be set at other locations on the ultrasound probe according to actual needs. The ultrasound probe body 1, as the core detection unit, integrates advanced ultrasonic transducer technology, is capable of transmitting and receiving high-quality ultrasonic signals, and thereby generating clear and accurate images of the stomach, providing doctors with a detailed basis for diagnosis.

[0036] The introduction of the clamping fixture 2 is intended to solve the problem of fixing the ultrasound probe under gastroscopy guidance. The clamping fixture 2 is set at the tail of the ultrasound probe body 1, and functionally realizes the stable clamping of the probe. In the area outside the connection hole 4, the clamping fixture 2 is also arranged with multiple clamping parts 5 that are connected as one or separated. The design of these clamping parts is flexible and can be adjusted and combined according to actual clamping needs. Each clamping part 5 is equipped with at least two clamping surfaces 6. These clamping surfaces have been precisely machined and processed to fit tightly to various surface materials and provide reliable clamping force. Of particular importance is that at least one clamping surface 6 of each clamping part 5 is also provided with an anti-slip structure 7. This innovative design effectively increases the friction between the clamping surface and the clamping object (such as biopsy forceps or gastroscopic operating forceps or other tools). Even in the moist and slippery environment of the stomach, it can ensure that the ultrasound probe is stable and does not slip. Through the control and guidance of the gastroscope, the doctor can flexibly adjust the posture and orientation of the ultrasound probe to perform a detailed ultrasound examination of every corner of the stomach.

[0037] In a specific embodiment, the clamping fixture 2 is connected to the tail or side wall of the ultrasound probe body 1, and the clamping fixture 2 is detachably connected to the ultrasound probe body 1 or

[0038] The clamping fixture 2 is fixedly connected to the ultrasonic probe body 1 to form an integrated structure.

[0039] In this embodiment, in order to meet different medical scenarios and user needs, the connection method between the clamping fixture 2 and the ultrasound probe body 1 is not fixed.

[0040] The clamping fixture 2 and the ultrasound probe body 1 can be connected in a detachable manner, which gives the ultrasound probe greater flexibility and convenience. In actual application, medical staff can easily assemble or disassemble the clamping fixture 2 and the ultrasound probe body 1 according to specific examination requirements or patient conditions. For example, when the probe needs to be deeply cleaned, maintained, or clamping fixtures of different specifications are replaced to accommodate different models of gastroscopes, the detachable design undoubtedly provides great convenience. In addition, this design also helps to extend the overall service life of the ultrasound probe, because each component can be replaced independently without scrapping the entire probe.

[0041] The clamping fixture 2 and the ultrasound probe body 1 can also be fixedly connected to form an integrated structure. This integrated design ensures the compactness and stability of the probe structure, and is suitable for medical scenarios with extremely high requirements for stability and durability. In the integrated structure, the clamping fixture 2 and the ultrasound probe body 1 are tightly combined through a precise manufacturing process to form an indivisible whole. Such a design not only reduces the connection gap between components and reduces the risk of failure due to loosening or falling off, but also enables the entire probe to move and position more stably under the guidance of the gastroscope, thereby improving the accuracy and efficiency of the examination. At the same time, the integrated structure also simplifies the operation process of the probe, reducing the operating steps and time costs of medical staff.

[0042] In a specific embodiment, the plurality of clamping portions 5 are evenly distributed, the angles between two adjacent clamping portions 5 are equal, and the outer edge of each clamping portion 5 includes a smooth layer.

[0043] In this embodiment, as shown in the attached Figure 3 As shown, the multiple clamping portions 5 on the clamping fixture 2 are cleverly arranged to achieve optimal clamping performance and user experience. These clamping portions 5 are not only appropriately numbered to accommodate clamping requirements of varying shapes and sizes, but are also evenly distributed within specific areas of the clamping fixture 2. This uniform distribution ensures that each clamping portion 5 can function independently and effectively, while also preventing probe deflection or instability caused by uneven clamping force distribution.

[0044] Furthermore, the angles between two adjacent clamping parts 5 are carefully designed to be equal, further enhancing the overall balance and stability of the clamping fixture 2. Equal angles mean that no matter where the probe is clamped, the clamping force it receives is uniform and stable, thereby ensuring precise control of the probe's posture and orientation in the stomach or other examination environments. In addition, in order to improve comfort and safety during the clamping process, a smoothing layer is specially added to the outer edge of each clamping part 5. This smoothing layer is made of soft and skin-friendly materials, such as medical-grade silicone or polymer elastomers, and its surface is finely ground and polished to present a smooth and rounded touch. The presence of the smoothing layer not only effectively reduces the friction and irritation between the clamping part 5 and the patient's internal tissues or gastroscopic operating forceps, reducing the patient's discomfort and pain, but also avoids the risk of tissue damage or bleeding caused by improper clamping. The design of the clamping fixture 2 not only improves the convenience and stability of the ultrasound probe in gastroscopy-guided ultrasound examinations, but also greatly improves the patient's examination experience and safety.

[0045] In a specific embodiment, the clamping fixture 2 includes multiple clamping parts 5 and connecting columns 8. The multiple clamping parts 5 are connected to the ultrasonic probe body 1. The connecting column 8 is connected to the side of the clamping part 5 away from the ultrasonic probe body 1. A connecting hole 4 is provided on the connecting column 8 for connecting the ultrasonic probe body 1 to the connecting cable 3.

[0046] In this embodiment, the clamping fixture 2 is composed of multiple clamping portions 5 and connecting posts 8. The clamping portions 5, as the core of the clamping fixture 2, are directly connected to the ultrasound probe body 1. These clamping portions 5 are not only rationally numbered and evenly arranged, ensuring probe stability and balance during the clamping process, but are also constructed from a flexible yet durable material to minimize potential probe damage and enhance patient comfort. Each clamping portion 5 is meticulously designed to closely conform to the shape and size of the probe, providing reliable clamping force while avoiding unnecessary friction and pressure.

[0047] The connecting post 8, another key component of the clamping fixture 2, is cleverly connected to the side of the clamping portion 5 facing away from the ultrasound probe body 1. Furthermore, a connection hole 4 is specially provided on the connecting post 8. This detailed design allows for smooth access to the connecting cable 3 of the ultrasound probe body 1, ensuring stable power and signal transmission while maintaining a clean and aesthetically pleasing overall appearance. In this embodiment, the connecting cable 3 utilizes ultra-fine flexible cable technology, with a wire diameter of approximately 1 mm, reducing overall weight. Furthermore, this ultra-fine cable exhibits excellent flexibility and wear resistance, ensuring stability and reliability during long-term use. Once the examination is complete, the connecting cable 3 can be used to guide the probe out of the digestive tract, avoiding additional discomfort and harm to the patient. This design not only enhances the overall structural strength of the clamping fixture 2 but also effectively protects the connecting cable 3. During use, when the clamping portion 5 tightly clamps the ultrasound probe body 1, the connecting post 8 effectively protects the connecting cable 3 from damage, ensuring unimpeded signal transmission between the ultrasound probe and external equipment.

[0048] In a specific embodiment, each clamping portion 5 includes two clamping surfaces 6 , and an arc-shaped structure facing the connecting hole 4 is formed between the two clamping surfaces 6 .

[0049] In this embodiment, each clamping portion 5 integrates two clamping surfaces 6, forming an arc-shaped structure facing the connection hole 4. This arc-shaped structure can better disperse and withstand the pressure from the ultrasound probe body 1, making the clamping process smoother and less likely to damage the probe. Furthermore, the arc-shaped structure increases the contact area between the clamping surfaces 6 and the probe surface, thereby improving the stability and reliability of the clamping and ensuring that the probe will not accidentally fall off due to external forces during the inspection process.

[0050] In a specific embodiment, the clamping portion 5 includes a prismatic protrusion structure and / or a columnar protrusion structure;

[0051] The anti-slip structure 7 includes a tooth-like structure and / or a concave-convex structure.

[0052] In this embodiment, specifically, the surface of the clamping portion 5 can be integrated with a prismatic protrusion structure or a columnar protrusion structure, which increases the friction when in contact with the ultrasonic probe body 1, thereby effectively preventing the probe from sliding or shifting during the inspection process and providing a more stable clamping effect.

[0053] In addition, in order to further improve the anti-slip performance of the clamping portion 5, the anti-slip structure 7 may include a toothed structure or a concave-convex structure, which can effectively increase the contact area and friction between the clamping tool and the clamping portion 5, providing a more stable clamping effect.

[0054] In one specific embodiment, multiple clamping portions 5 are evenly distributed and form a symmetrical shape, with the connection hole 4 located at the center of the symmetrical shape. In this embodiment, to enhance device stability and operational efficiency, the clamping portions 5 are spatially arranged in a symmetrical manner. This facilitates uniform force distribution during the clamping process, preventing displacement or damage caused by uneven force distribution. This is particularly suitable for applications requiring high-precision positioning and secure clamping. Furthermore, the connection hole 4 located at the center of the symmetrical shape further enhances overall stability and reliability.

[0055] In one specific embodiment, the ultrasound probe body 1 comprises a capsule-like structure, and the surface smoothness of the ultrasound probe body 1 reaches a preset value. In this embodiment, the capsule-like design of the ultrasound probe body 1 enables the probe to be safely and conveniently swallowed directly by the patient. This non-invasive testing method greatly reduces the patient's pain and improves the comfort and acceptance of the diagnosis. Furthermore, the smoothness of the surface of the ultrasound probe body 1 reaches a preset value, which not only reduces friction between the probe and the digestive tract wall, reducing the risk of irritation and damage to the digestive tract, but also promotes the natural flow of the probe within the digestive tract, ensuring a smooth detection process.

[0056] Furthermore, a highly smooth surface helps reduce the scattering and reflection of sound waves, improving the clarity and accuracy of ultrasound imaging. When the probe is operating within the upper digestive tract, its smooth surface ensures uniform transmission and reception of ultrasound waves, enabling more detailed and accurate information about internal structures, providing doctors with powerful diagnostic evidence.

[0057] In a specific embodiment, the ultrasound probe body 1 includes a shell 14 and a camera module 9, an ultrasonic transducer 10 and a driving unit 11 for driving the ultrasonic transducer 10 to rotate, which are arranged inside the shell 14. The connecting cable 3 passes through the connecting hole 4 and electrically connects the camera module 9 and the driving unit 11 respectively.

[0058] In this embodiment, as shown in the attached Figure 4 As shown, the ultrasound probe body 1 exhibits a high degree of integration and intelligence. Its core consists of a durable housing 14, which not only protects the delicate components within from environmental influences but also provides a stable operating platform. Several key components are cleverly arranged within housing 14, including a high-definition camera module 9, an efficient ultrasonic transducer 10, and the crucial drive unit 11.

[0059] The camera module 9, as the core of visual information acquisition, can capture and transmit images of the area to be detected in real time, providing intuitive visual feedback to the operator. The ultrasonic transducer 10 is the core component of ultrasonic detection technology, responsible for converting electrical signals into ultrasonic waves and sending them to the object to be detected. At the same time, it receives the reflected ultrasonic signals, converts them into electrical signals for processing, and obtains the internal structure information of the object. In order to achieve more comprehensive detection coverage, the drive unit 11 is integrated into the probe, and its main function is to drive the ultrasonic transducer 10 to achieve 360° circular scanning motion. This all-round scanning method can ensure that there are no blind spots in the detection area and improve the accuracy and reliability of the detection. The implementation methods of the drive unit 11 are flexible and diverse, including but not limited to the use of high-precision motor drive methods, and the smooth rotation of the ultrasonic transducer is achieved by accurately controlling the speed and rotation angle of the motor.

[0060] Furthermore, connecting cable 3, serving as a bridge for data transmission and power supply, establishes an electrical connection with camera module 9 and drive unit 11 within housing 14 by passing through connecting hole 4. This design not only simplifies the probe's external connection structure but also ensures stable and efficient data transmission. Through connecting cable 3, the probe can transmit collected image information and ultrasound data in real time to an external processing system for further analysis and processing.

[0061] In a specific embodiment, an optical sensor 12 and a lighting lamp 13 are further provided at one end of the housing 14 away from the clamping fixture 2 . The optical sensor 12 and the lighting lamp 13 are electrically connected to the connecting cable 3 , respectively.

[0062] In this embodiment, in addition to the core detection and scanning functions, the housing 14 is also carefully arranged with an optical sensor 12 and a lighting lamp 13 at the end away from the clamping fixture 2, which not only broadens the detection capability of the probe, but also improves its applicability in complex environments.

[0063] Specifically, the optical sensor 12 utilizes high-resolution complementary metal oxide semiconductor (CMOS) technology, capable of capturing and transmitting extremely detailed and clear image information. This high-resolution optical sensor is crucial for acquiring optical images of the forward field of view, capturing details that are difficult to detect with traditional ultrasonic testing, providing operators with a more intuitive and comprehensive diagnostic basis.

[0064] Meanwhile, the illuminator 13, as an auxiliary device for the optical sensor 12, is cleverly installed at the front end of the probe. LED lighting technology, with its high efficiency, energy saving, and long life, provides sufficient and uniform illumination for the detection area. This not only ensures that the optical sensor 12 can function properly in low-light environments, but also improves the brightness and contrast of the image, further enhancing the visual quality.

[0065] At the same time, both the optical sensor 12 and the illuminator 13 are electrically connected to the external system via a connecting cable 3. This connection method not only simplifies the internal structural design of the probe but also ensures the stability and reliability of data transmission. Through the connecting cable 3, the probe can transmit the collected optical images in real time to an external display device or processing system for further analysis and diagnosis by the operator.

[0066] In actual applications, the most appropriate imaging method or a combination of multiple imaging methods can be selected according to the patient's specific situation and needs, including but not limited to optical coherence tomography (OCT), nuclear magnetic resonance imaging (NMRI), and positron emission computed tomography (PET).

[0067] The utility model provides a miniaturized single-array circular scanning ultrasound probe with a rotary drive device located at the front end of the probe. The probe has a capsule shape and can be swallowed or pushed into the digestive tract. A prismatic or columnar protrusion structure is provided at the rear end of the ultrasound probe to facilitate clamping and fixing with biopsy forceps or other tools. The probe's posture and orientation in the digestive tract can be controlled through an endoscope to achieve ultrasound examination. The utility model has low cost and is flexible to use. It provides a more effective and convenient means for diagnosing relevant ultrasound examination indications in the digestive tract, thereby promoting the development of endoscopic minimally invasive surgical treatment in primary hospitals.
