Description

Technical Field

[0001] This utility model belongs to the field of ultrasonic probe technology, and in particular relates to an ultrasonic probe water-coupled wrapping device. Background Technology

[0002] Ultrasound waves are sound waves with frequencies higher than 20,000 Hz. They have good directionality, strong penetrating power, and are easy to concentrate. They can travel long distances in water. In medicine, due to the harmlessness of ultrasound to the human body, ultrasound detection technology is widely used in tissue morphology detection, organ disease diagnosis, assessment of blood vessel patency, fetal development, and so on. Ultrasonic vibrations can cause the movement of substances within tissue cells. Due to the subtle massage of ultrasound, the cytoplasm flows, cells vibrate, rotate, and rub, thus producing a cell massage effect, also known as "internal massage." This is a unique characteristic of ultrasound therapy. It can change the permeability of cell membranes, stimulate the diffusion process of cell semipermeable membranes, promote metabolism, accelerate blood and lymphatic circulation, improve cellular ischemia and hypoxia, improve tissue nutrition, change protein synthesis rate, and enhance regenerative function.

[0003] Transcranial focused ultrasound (TUS) is a revolutionary non-invasive neuromodulation technique based on decades of experience with focused ultrasound technology. Instead of electrical or magnetic stimulation, TUS uses finely tuned ultrasound waves that can be focused on precise targets anywhere in the brain. TUS / tFUS can target deeper brain regions, achieving painless, non-invasive, and deep brain stimulation.

[0004] While existing ultrasonic probe water-coupling devices meet the basic requirements for ultrasonic wave propagation and probe protection to a certain extent, they still face many challenges in practical applications. Many existing devices have defects in the sealing design between the probe and the housing, and between the housing and the front and rear end covers, which makes it easy for moisture to seep into the device. This not only affects the propagation effect of ultrasonic waves, but may also damage the probe and electronic components. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the prior art by providing a water-coupled encapsulation device for an ultrasonic probe.

[0006] To achieve the above objectives, the utility model employs the following technical solution: an ultrasonic probe water-coupled wrapping device, comprising a wrapping shell, a rear end cover at one end of the wrapping shell, an mounting position on the inner side of the wrapping shell, a probe fitted to the rear end cover at the mounting position, a front end cover at the end of the wrapping shell away from the rear end cover, a TPU film between the front end cover and the wrapping shell, a water channel on the inner side of the wrapping shell, the water channel being distributed around the probe, and a connector on the wrapping shell connecting to the water channel.

[0007] By adopting the above technical solution, the device provides a stable and sealed working environment for the probe through the encapsulated housing. The design of the rear cover allows the probe to be firmly installed inside the encapsulated housing. The combination of the front cover and the TPU film ensures that the ultrasonic waves can smoothly penetrate and reach the target area, while preventing leakage of the water coupling agent.

[0008] Optionally, the rear end cover is concave, and a pair of first sealing grooves are provided on the side wall of the rear end cover, with a first sealing ring provided on the inner side of each pair of first sealing grooves.

[0009] By adopting the above technical solution, the concave design of the rear end cover can better fix and support the probe, preventing it from shifting during use. The combination of the first sealing ring and the first sealing groove ensures the sealing between the rear end cover and the enclosure, preventing leakage of the water coupling agent and the intrusion of external impurities.

[0010] Optionally, a pair of second sealing grooves are provided at one end of the rear cover near the probe, and a second sealing ring is provided on the inner side of each pair of second sealing grooves.

[0011] By adopting the above technical solution, the setting of the second sealing ring and the second sealing groove further enhances the sealing between the probe and the rear end cover, ensuring the stability and safety of the probe. This helps to prevent the water coupling agent from leaking from the gap between the probe and the rear end cover, while also preventing the entry of external contaminants.

[0012] Optionally, a conduit is installed at one end of the probe near the rear end cover, and a through hole is provided at the end of the rear end cover near the probe for the conduit to pass through.

[0013] By adopting the above technical solution, the design of the conduit provides a connection channel between the probe and the external circuit, enabling the ultrasonic signal to be smoothly transmitted to the external device for processing and analysis.

[0014] Optionally, the front end cover is annular, and the front end cover is connected to the outer wall of the enclosure shell in a wrapping manner. The side wall of the front end cover is provided with a pair of third sealing grooves, and a third sealing ring is installed on the inner side of each pair of third sealing grooves.

[0015] By adopting the above technical solution, the annular design of the front cover allows it to better fit with the packaging shell, forming a stable sealing structure.

[0016] Optionally, the water channel includes an annular channel and a plurality of longitudinal channels communicating with the annular channel, the plurality of longitudinal channels being symmetrically distributed on the inner periphery of the enclosing shell.

[0017] By adopting the above technical solution, the design of the annular groove and longitudinal groove of the water flow channel allows the water coupling agent to be evenly distributed on the inner side of the encapsulation shell, thereby improving the propagation efficiency and focusing performance of ultrasonic waves. The symmetrical distribution of the longitudinal groove ensures the uniform flow of the water coupling agent in the encapsulation shell, avoiding the occurrence of local accumulation or drying phenomena.

[0018] Optionally, the diameter of the TPU film is larger than the diameter of the front end cap, and the TPU film is installed by abutting against the front end cap and the enclosure shell.

[0019] By adopting the above technical solution, the design of the TPU film allows for easy assembly and disassembly of the TPU film, while ensuring the airtightness between the TPU film and the encapsulating shell.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This device employs a water-encased design for the entire probe, fully utilizing the characteristic that ultrasound attenuates most slowly in water, thereby effectively improving the propagation efficiency and focusing performance of ultrasound waves. This design not only ensures that ultrasound waves can be accurately and efficiently transmitted to the target area but also significantly reduces signal loss during propagation. 2. The device utilizes a multi-ring sealing design between the probe and the housing, and between the housing and the front and rear end covers, including a first, second, and third sealing ring. These sealing rings together form a tight waterproof barrier, effectively preventing the infiltration of moisture and other impurities. This design not only protects the probe and electronic components from damage but also ensures the stability and cleanliness of the internal environment of the device. 3. The device features internal water channels, including annular channels and longitudinal channels connected to the annular channels. These channels not only facilitate water injection from the rear to the front but also promote water circulation and renewal. This design not only ensures that the device is always filled with fresh water or water coupling agent but also improves the propagation efficiency of ultrasound waves and the heat dissipation performance of the probe.

Therefore, they should not be construed as limitations on this utility model.

[0029] like Figure 1 As shown in Figure 4, the specific solution of the embodiment is as follows: An ultrasonic probe water-coupled wrapping device includes a wrapping shell 1. The wrapping shell 1 is the main structure of the entire device, used to accommodate and protect the probe 3, the conduit 301 and other components inside. It provides a reference surface for installing the rear end cover 2, the front end cover 4 and the sealing ring, and provides sufficient strength and rigidity to resist the pressure and impact of the external environment.

[0030] One end of the housing 1 is provided with a rear end cover 2, which is concave. The concave design of the rear end cover 2 is used to fix and support the probe 3. The side wall of the rear end cover 2 has a first sealing groove 201 for installing a pair of first sealing rings 8. The arrangement of the first sealing rings 8 and the first sealing groove 201 ensures the sealing between the rear end cover 2 and the housing 1. The end of the rear end cover 2 near the probe 3 has a second sealing groove 202 for installing a pair of second sealing rings 9. The design of the second sealing rings 9 further ensures the sealing between the probe 3 and the rear end cover 2, effectively fixing and protecting the probe 3, preventing it from shifting or being damaged during use, improving the overall sealing performance of the device, and preventing moisture and impurities from entering the device.

[0031] The inner side of the housing 1 is provided with a mounting position 11, on which a probe 3 is mounted to fit against the rear end cover 2. The mounting positions 11 are distributed around the inner wall of the housing 1. The probe 3 is the core component of the device, used to emit and receive ultrasonic waves, ensuring accurate emission and reception of ultrasonic waves, and improving the accuracy and effectiveness of detection or treatment. A conduit 301 is installed on one end of the probe 3 near the rear end cover 2. A wire is provided on the probe 3 inside the conduit 301. The conduit 301 is used to protect the wire and prevent it from detaching during use. If the probe is damaged, the conduit 301 is used to protect the wire and prevent it from being damaged during use. This facilitates the installation and fixing of the wire and reduces maintenance costs. The probe 3 has a wire located inside the conduit 301 for connecting to the external circuit to realize signal transmission and control. The end of the rear cover 2 near the probe 3 has a through hole 203 for the conduit 301 to pass through. The through hole 203 allows the conduit 301 to pass through, realizing the connection between the probe 3 and the external circuit. This facilitates the installation and fixing of the conduit 301 and ensures the normal operation of the probe 3.

[0032] The end of the packaging shell 1 away from the rear end cover 2 is provided with a front end cover 4. The front end cover 4 is annular and is designed to close the front end of the packaging shell 1. The side wall of the front end cover 4 is provided with a third sealing groove 401 for installing a pair of third sealing rings 10. The design of the third sealing rings 10 and the third sealing groove 401 ensures the sealing between the front end cover 4 and the packaging shell 1, prevents moisture and impurities from entering the device, enhances the overall structural strength of the device, and improves its impact resistance.

[0033] A TPU film 5 is provided between the front cover 4 and the enclosure shell 1. The diameter of the TPU film 5 is larger than the diameter of the front cover 4. The TPU film 5 is installed by abutting against the front cover 4 and the enclosure shell 1. The TPU film 5 is made of highly elastic material, thin, resistant to low temperature and aging, which facilitates ultrasonic penetration, improves the sealing and waterproof performance of the front end of the device, ensures that ultrasonic waves can smoothly penetrate the film, reduces signal attenuation, extends the service life of the device, and reduces maintenance costs.

[0034] The inner side of the housing 1 is provided with a water flow channel 6. The water flow channel 6 includes an annular channel and several longitudinal channels communicating with the annular channel. The several longitudinal channels are symmetrically distributed on the inner circumference of the housing 1. The design of the water flow channel 6 ensures that the water coupling agent can be evenly distributed around the probe 3, which improves the propagation efficiency of ultrasonic waves, improves the propagation efficiency and focusing performance of ultrasonic waves, ensures that the probe 3 can be effectively cooled during operation, facilitates the injection and discharge of the water coupling agent, and simplifies the operation process.

[0035] The enclosure 1 is provided with a connector 7 that is connected to the water channel 6. The connector 7 is an integrated water inlet and vent outlet. The connector 7 is connected to the water channel 6, which realizes the injection and venting functions of the water coupling agent, improves the injection and venting efficiency of the water coupling agent, ensures that the inside of the device is always full of fresh water coupling agent, and improves the propagation effect of ultrasound.

[0036] A pair of first sealing rings 8 are provided between the rear end cover 2 and the packaging shell 1, a pair of second sealing rings 9 are provided between the rear end cover 2 and the probe 3, and a pair of third sealing rings 10 are provided between the front end cover 4 and the packaging shell 1. The design and material selection of the sealing rings can resist the pressure and corrosion of the external environment, extend the service life of the device, and improve its reliability and stability.

[0037] The working principle of the above embodiments is as follows:

[0038] Inject degassed water through the water inlet on connector 7 to ensure that the device is filled with fresh water coupling agent. At the same time as injecting degassed water, expel the air inside the device through the exhaust port to ensure that the water coupling agent can fully fill and cover probe 3.

[0039] Apply gel to the gaps where the TPU film 5 contacts the patient's head to ensure that the ultrasound waves can propagate well to the focal point. The gel should be applied evenly and in appropriate amounts to ensure smooth propagation of the ultrasound waves.

[0040] The device is activated so that probe 3 begins to emit ultrasound. The ultrasound waves propagate through the TPU film 5 and the gel, reach the patient's head, and are focused on the target area. The frequency, intensity, and duration of the ultrasound waves are adjusted according to the needs of detection or treatment.

[0041] After use, promptly clean the residue and water coupling agent inside the device.
