Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, and in particular relates to a mechanically adjustable focused ultrasound focal point 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 more. It allows doctors to see the condition of internal tissues in advance, enabling early diagnosis and treatment. Now, with the further development of ultrasound technology, ultrasonic lithotripsy and ultrasonic scalpels have been applied, allowing patients to undergo surgery without incisions (or with only a few incisions), greatly reducing patient pain and surgical risks.

[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] During transcranial focused ultrasound stimulation, multiple ultrasound beams are focused onto a single focal point by continuously stimulating the transducer probe. Because head size and treatment area depth vary, the focal point position needs to be adjusted according to the patient's stimulation point. The precision of this technique is crucial, as there are significant individual differences in head size, skull structure, and treatment area depth. Therefore, to ensure maximum treatment effectiveness, the focal point position must be precisely adjusted according to each patient's specific stimulation point. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the prior art by providing a mechanically adjustable focused ultrasound focal point device.

[0006] To achieve the above objectives, the utility model adopts the following technical solution: a mechanically adjustable focused ultrasound focal point device, comprising a housing, a first end cap installed at one end of the housing, an electric push rod provided at the end of the first end cap near the housing, and a probe provided at the output end of the electric push rod; a second end cap installed at the end of the housing away from the first end cap, a TPU film provided between the second end cap and the housing, and a connecting chamber provided at the end of the housing near the second end cap.

[0007] By adopting the above technical solution, the device achieves effective adjustment of the ultrasonic focus by designing a mechanical structure that includes a housing, a first end cap, and a second end cap. The first end cap and the second end cap are respectively installed at both ends of the housing, forming a sealed and adjustable internal space, which provides a reliable basis for the stable operation of the ultrasonic probe and the adjustment of the focus.

[0008] Optionally, the sidewall of the housing is provided with a connecting joint.

[0009] By adopting the above technical solution, the connection joint allows the device to be connected to other equipment, supply liquid and vent air to the inside of the housing, and enhances the scalability and applicability of the device.

[0010] Optionally, the diameter of the first end cap is larger than the diameter of the second end cap, a second sealing groove is provided on the side wall of the first end cap, and a second sealing ring is provided on the inner side of the second sealing groove; a pair of ear plates are installed on one end of the second end cap located inside the housing, and a connecting pin is provided on the pair of ear plates.

[0011] By adopting the above technical solution, the diameter of the first end cap is larger than that of the second end cap. This design not only optimizes the appearance and force distribution of the device, but also facilitates the installation of components such as electric push rods on the first end cap. At the same time, the setting of the second sealing groove and the first sealing groove, together with the corresponding sealing ring, ensures the sealing of the device and prevents ultrasonic leakage and the influence of the external environment on the device.

[0012] Optionally, a connecting seat is installed at one end of the electric push rod near the first end cover, and the connecting seat is connected to the connecting pin.

[0013] By adopting the above technical solution, by installing an electric push rod on the first end cover and connecting it to the ear plate on the second end cover through a connecting seat and connecting pin, the electric push rod is stably installed and effectively driven. This design enables the electric push rod to precisely control the movement of the probe, thereby achieving precise adjustment of the ultrasonic focus.

[0014] Optionally, the probe has a number of grooves on its outer periphery, and the inner sidewall of the housing has a pair of slide rails, which are connected to one of the pairs of grooves.

[0015] By adopting the above technical solution, the outer periphery of the probe is provided with a groove, which is connected to the slide rail seat on the inner side wall of the housing to form a stable sliding structure. This design not only ensures the stability of the probe during movement, but also reduces friction and wear, and extends the service life of the device.

[0016] Optionally, a mounting base is installed at one end of the probe near the electric push rod, and a fixing pin is provided on the mounting base. The output end of the electric push rod is connected to the fixing pin.

[0017] By adopting the above technical solution, a fixing pin is set on the mounting base and connected to the output end of the electric push rod, so as to achieve reliable fixation and effective transmission of the probe. This design ensures that the probe can move smoothly and accurately under the drive of the electric push rod, thereby achieving precise control of the ultrasonic focus.

[0018] Optionally, the second end cap is annular, and a first sealing groove is provided on the side wall of the second end cap for the installation of the first sealing ring, and a first sealing ring is provided on the inner side of the first sealing groove.

[0019] By adopting the above technical solution, the second end cap is annular, and the first sealing groove opened on its side wall is used to install the first sealing ring, which further enhances the sealing performance inside the device. This design prevents ultrasonic leakage and the influence of the external environment on the inside of the device, and improves the stability and reliability of the device.

[0020] Optionally, the cross-section of the connecting chamber is a hollow trapezoidal shape, and the diameter of the connecting chamber near the second end cap is smaller than the diameter of the probe.

[0021] By adopting the above technical solution, the connecting chamber is hollow trapezoidal in shape, and the diameter of the end near the second end cap is smaller than the diameter of the probe. This design not only optimizes the internal structure of the device, but also allows the probe to gradually approach the focal area during movement, thereby achieving precise adjustment of the ultrasonic focal point. At the same time, the design of the connecting chamber also takes into account the size and range of movement of the probe, ensuring the stability and safety of the probe during movement.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This device achieves mechanical adjustment of the focal point position through the connection between the electric push rod and the probe. Compared with the traditional electronic phase-controlled focusing method, mechanical focusing has the advantages of simple structure, convenient operation, and high adjustment precision. By precisely controlling the extension and retraction distance of the electric push rod, minute adjustments to the focal point position can be achieved, thereby meeting the needs of different patients with different head sizes, skull structures, and treatment depths, improving the accuracy of treatment. 2. The device is filled with a coupling agent (such as degassed water) inside the shell, which reduces attenuation and scattering of ultrasound waves during propagation, improving propagation efficiency and penetration. At the same time, the front of the probe is sealed with a TPU film, which facilitates ultrasound penetration and further improves the treatment effect. 3. By precisely adjusting the focal point position, this device can stimulate precise targets anywhere in the brain, thereby achieving effective regulation of the nervous system. This treatment method avoids the trauma and pain of traditional surgery, greatly reducing patient suffering and surgical risks. Attached Figure Description

[0031] A first end cap 2 is installed at one end of the housing 1. The first end cap 2 is used to fix the electric push rod 3 and provide it with an installation position, while forming a seal with the housing 1. The diameter of the first end cap 2 is larger than the diameter of the second end cap 5. A second sealing groove 201 is provided on the side wall of the first end cap 2. A pair of ear plates 202 are installed at the end of the first end cap 2 located inside the housing 1. A connecting pin 203 is provided on the pair of ear plates 202. The diameter of the ear plates 202 is larger than that of the second end cap 5, which facilitates differentiation and installation. The second sealing groove 201 on the side wall is used to install the second sealing ring 8 to enhance the sealing performance. The design of the ear plates 202 and the connecting pin 203 is used to connect the connecting seat 301 of the electric push rod 3 to ensure the stable movement of the probe 4.

[0032] An electric push rod 3 is provided at one end of the first end cap 2 near the housing 1. The electric push rod 3 serves as a power source and pushes the probe 4 back and forth through telescopic movement to achieve mechanical adjustment of the focal point. The electric push rod 3 has a compact structure, is easy to operate, and has high adjustment accuracy. A connecting seat 301 is installed at one end of the electric push rod 3 near the first end cap 2. The connecting seat 301 is connected to the connecting pin 203. The cooperation between the connecting seat 301 and the connecting pin 203 ensures a reliable connection between the electric push rod 3 and the probe 4.

[0033] The output end of the electric push rod 3 is equipped with a probe 4. The probe 4 emits ultrasonic waves and, by moving, changes the focal position to stimulate a precise target in the brain. The travel distance of the probe 4 is 0-50mm. The probe 4 and the electric push rod 3 are respectively provided with wires 403 that penetrate and extend to the outside of the housing 1. The wires 403 are used to connect to external devices and transmit signals and power. The outer periphery of the probe 4 is provided with several grooves 404. The grooves 404 are designed so that the water in front of and behind the probe 4 can be exchanged when the probe 4 moves back and forth. The inner wall of the housing 1 is provided with a pair of... The slide rail 101, a pair of slide rail 101 are connected to one pair of grooves 404. The slide rail 101 provides guidance and limiting function for the probe 4, ensuring the stability and accuracy of the probe 4 during movement. It fits tightly with the groove 404 of the probe 4, reducing friction and resistance during movement. The end of the probe 4 near the electric push rod 3 is equipped with a mounting base 401.

The design of the mounting base 401 and the fixing pin 402 facilitates connection with the output end of the electric push rod 3.

[0034] A second end cap 5 is installed at the end of the housing 1 away from the first end cap 2. The second end cap 5 forms a seal with the housing 1 and protects the internal components. The second end cap 5 is annular. The side wall of the second end cap 5 has a first sealing groove 501 for the installation of the first sealing ring 7. The design is annular to facilitate the fit with the housing 1. The side wall has a first sealing groove 501 for installing the first sealing ring 7 to enhance the sealing performance.

The material is soft and easy to seal. At the same time, it is easy for ultrasound to penetrate and improve the treatment effect.

[0035] A first sealing ring 7 is provided between the second end cap 5 and the housing 1, and a second sealing ring 8 is provided between the first end cap 2 and the housing 1. The first sealing ring 7 and the second sealing ring 8 enhance the sealing between the first end cap 2 and the second end cap 5 and the housing 1, preventing the coupling agent from leaking. Both the first sealing ring 7 and the second sealing ring 8 are O-rings. The second sealing ring 8 is located inside the second sealing groove 201. A connecting chamber 9 is provided at the end of the housing 1 near the second end cap 5. The inside of the connecting chamber 9 is filled with degassed water. The connecting chamber 9 is frustum-shaped. The diameter of the connecting chamber 9 at the end near the second end cap 5 is smaller than the diameter of the probe 4. The connecting chamber 9 is located at the end of the housing 1 near the second end cap 5 and is used to contain the coupling agent (such as degassed water) and serve as a limiting structure for the probe 4. It is designed as a hollow trapezoidal shape. The diameter at the end near the second end cap 5 is smaller than the diameter of the probe 4, ensuring the limiting and stability of the probe 4 during movement. The inside is filled with degassed water, which improves the propagation efficiency and penetration ability of ultrasonic waves.

[0036] The working steps of the above embodiments are as follows:

[0037] The extension and retraction of the electric push rod 3 is controlled by an external device, which pushes the probe 4 to move back and forth inside the housing 1. The travel of the probe 4 is 0-50mm, which can be precisely adjusted as needed.

[0038] As the probe 4 moves, the focal position of the ultrasonic waves emitted by the probe 4 will also change accordingly. The moving distance of the probe 4 can be precisely controlled by external equipment to stimulate the precise target in the brain. Gel is applied to the gap between the TPU film 6 and the head so that the ultrasonic waves can be well propagated to the focal position.

[0039] During the operation of the device, it is connected to external equipment through the wire 403 of the probe 4 to transmit signals and power in real time. The external equipment can monitor parameters such as the position of the probe 4 and the intensity of the ultrasonic waves, and make adjustments as needed.

[0040] After treatment, turn off the electric push rod 3 and the ultrasonic transmitter, drain the degassed water from the housing 1 through the connecting joint 102, and perform necessary cleaning and maintenance on the device.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
