Description

TECHNICAL FIELD

[0001] The application relates to the technical field of medical instruments, and more particularly to an ultrasonic treatment head and an ultrasonic treatment instrument. BACKGROUND

[0002] The ultrasonic treatment instrument is a device for skin care treatment by using focused ultrasonic waves. The basic principle is to use the mechanical vibration and thermal effect of ultrasonic waves to stimulate and treat the skin in a deep layer, so as to generate coagulation points in the human tissue (fascia layer, superficial fascia layer and superficial fat layer, and dermis layer), and achieve the effects of fascia reset and stimulation of collagen and elastin regeneration.

[0003] Since the focused ultrasonic treatment emits pulse waves, the energy of the focused ultrasonic waves is very high. If the same part of the human body continuously receives pulse waves, skin damage is likely to occur.

By moving the ultrasonic treatment head, it is determined whether the treatment area is moved. When the movement speed of the acceleration sensor of the ultrasonic treatment head is relatively slow, the acceleration sensor cannot accurately identify whether the treatment instrument and the treatment area are moved, resulting in the defect of poor treatment effect.

[0037] In the embodiment, the end of the inner shell 14 away from the base 13 is flush with the end of the outer shell 15 away from the base 13, and the treatment window 12 is configured to be open at the end of the outer shell 15 away from the base 13.

[0038] The mounting cavity 11 is arranged in the inner shell 14, that is, the mounting cavity 11 is a cavity formed by the inner shell 14, and the mounting cavity 11 is configured as a sealed cavity. The sealing effect between the inner shell 14 and the base 13 is achieved by arranging a sealing ring between the inner shell 14 and the base 13, and a bolt is arranged to pass through the inner shell 14 and press the sealing ring to achieve the sealing between the inner shell 14 and the base 13.

[0039] The ultrasonic transducer 2 is fixedly arranged on the base 13 through a mounting bracket, that is, one end of the mounting bracket is fixedly connected with the base 13, and the other end is fixedly connected with the ultrasonic transducer 2. The ultrasonic transducer 2 is a device for emitting ultrasonic waves. The ultrasonic transducer 2 is arranged towards the treatment window 12, and the central axis of the ultrasonic transducer 2 passes through the center of the treatment window 12, which helps to ensure that the sound waves can be accurately focused on the treatment area through the treatment window 12, ensures the directional propagation and efficient use of ultrasonic waves, so that the energy is concentrated on the target tissue, reducing the side effects on the surrounding normal tissue.

[0040] In the embodiment, a sound-conducting medium is arranged in the mounting cavity 11. The sound-conducting medium is a bridge for the ultrasonic waves to propagate from the ultrasonic transducer 2 to the target medium (such as human tissue, liquid, solid, etc.). The ultrasonic transducer 2 converts electrical signals into mechanical vibrations through the piezoelectric effect, and these vibrations need to pass through the sound-conducting medium to be effectively propagated to the target area; at the same time, the sound-conducting medium can maximize the reduction of sound wave reflection and improve the transmission efficiency of sound waves by optimizing acoustic impedance. By selecting a suitable sound-conducting medium, the sound field distribution can be optimized, so that the ultrasonic waves form a more uniform and concentrated sound field in the target area, thereby improving the detection or treatment effect. During the ultrasonic treatment process, the ultrasonic transducer 2 continuously works to generate heat, and the sound-conducting medium can also exchange heat generated by the ultrasonic transducer 2, thereby assisting in heat dissipation to achieve the effect of cooling. By cooling the ultrasonic transducer 2, it can prevent the treatment area from being damaged due to excessive temperature of the ultrasonic treatment head, and improve the use safety of the ultrasonic treatment head.

[0041] The ultrasonic transducer 2 is provided with a mounting groove 21, and the imaging unit 3 is arranged in the mounting groove 21, and the imaging unit 3 is arranged corresponding to the treatment window 12. Through the imaging unit 3, the recognition accuracy of the treatment head is improved, which can accurately identify the slight movement between the treatment head and the measured skin, judge the fitting degree between the treatment head and the measured skin, so as to maintain the safety and effectiveness of the treatment process, thereby improving the treatment effect.

[0042] In some embodiments, the mounting groove 21 is located at the central position of the ultrasonic transducer 2, and the imaging unit 3 is fixedly arranged in the mounting groove 21. The imaging unit 3 is used for imaging the treatment area at the treatment window 12.

[0043] In other embodiments, the imaging unit 3 is slidingly arranged in the mounting groove 21, and the imaging unit 3 is moved relative to the ultrasonic transducer 2 to adjust the imaging position. When the imaging unit 3 can be moved relative to the ultrasonic transducer 2, more angle data of the treatment area can be collected at different positions, increasing the diversity and richness of the data, which helps to generate higher precision imaging, thereby improving the overall image resolution; compared with the fixed single-point imaging which is easily affected by local reflection and other factors to cause artifacts, by adjusting the position of the imaging unit 3, multiple measurement results can be obtained, and the algorithm can be used to eliminate these non-ideal components, and finally more accurate and reliable image information is obtained, thereby improving the recognition accuracy of the treatment head.

[0044] The illumination unit 5 is arranged in the mounting cavity 11, and is used to supplement light to the treatment area at the treatment window 12. In the case of insufficient ambient light, the overall brightness of the scene can be directly enhanced by increasing the illumination unit 5, which can better distinguish the difference between the true signal and the noise, thereby reducing the image noise caused by weak light, improving the picture effect captured by the imaging unit 3, and making the imaging effect brighter and clearer, so as to further improve the image quality of the imaging unit 3. In the embodiment, the illumination unit 5 emits light outward from the treatment window 12, and the illumination unit 5 is located on the side of the shell assembly 1 close to the treatment window 12. The illumination unit 5 is preferably a ring-shaped light source, which aims to not block the energy transmission path of the ultrasonic transducer 2, while ensuring that the illumination can uniformly irradiate to the skin surface, improving the imaging effect of the imaging unit 3. The center of the ultrasonic transducer 2, the center of the imaging unit 3 and the center of the treatment window 12 are located on the same straight line, which can ensure that the viewing angle of the imaging unit 3 is perpendicular to the treatment area, preventing being blocked by the inner shell 14, and the imaging unit 3 can collect more complete and clear images through the treatment window 12.

[0045] In the embodiment, the imaging unit 3 is preferably a high-speed macro camera. The high-speed macro camera has high resolution and close-up focusing capability, can focus on very small objects, and capture close-up images that ordinary lenses cannot present. Secondly, the high-speed macro camera can continuously capture images in a short time, which is conducive to real-time imaging of the treatment area, avoids the problem of unclear imaging, and presents high-definition images, which is convenient for comparing the image differences under different frame numbers.

[0046] The following is the working process of the treatment head treatment.

[0047] First, a coupling agent is applied to the treatment area. The coupling agent is used to make the acoustic impedance of the medium on both sides of the interface between the treatment head and the human skin as close as possible, forming a good conduction path to reduce the reflection or scattering of ultrasound energy, allowing more ultrasound energy to enter the human body, thereby improving energy transmission efficiency. On the other hand, it reduces the possibility of local overheating caused by the treatment head being directly attached to a certain area for a long time. The appropriate thickness and mild and moist coupling agent can play a buffering role to a certain extent, preventing the risk of burns and increasing the patient's comfort. The coupling agent also has a lubricating effect, which helps to reduce the friction between the treatment head and the treatment area, allowing doctors to more easily and freely control the movement of the treatment head, ensuring gentle, smooth and unobstructed techniques, thereby improving the treatment experience.

[0048] Then, the treatment head is manipulated so that the treatment window 12 is aligned with the treatment area. The ultrasound transducer 2 creates thermal damage in the treatment area. The ultrasound energy generates a thermal effect in the subcutaneous tissue, causing collagen fibers to denature and contract, thereby immediately improving the tightening effect. At the same time, the thermal damage activates the skin's self-repair mechanism, promoting the generation of new collagen and elastin fibers, further improving skin laxity and wrinkles. The ultrasound energy typically acts at the following depths: 4.5mm depth (SMAS fascia layer): Deep lifting is achieved by stimulating the fascia layer to contract through thermal energy, improving facial laxity; 3.0mm depth (superficial fascia layer): Tightens the skin, reduces fat cells, and improves facial contours; 2.0mm depth (dermis): Stimulates collagen regeneration, reducing fine lines and wrinkles.

[0049] Because the range of a single irradiation is limited, in order to ensure that all treatment areas are adequately treated, the doctor needs to hold the treatment head and slide it across the skin surface so that the ultrasound transducer 2 can create a continuous or intermittent thermal damage path under the skin. Usually, the treatment head is slid back and forth along the skin surface to gradually advance until the treatment of the entire treatment area is completed. During treatment, the imaging unit 3 rapidly images the skin of the treatment area through the treatment window 12, reads the current skin image to find feature points, and multiple feature points can be set to improve accuracy. By comparing the positional changes of the same feature point in images at different frame rates, the position coordinates are transmitted to the main control unit 4. The main control unit 4 determines whether the treatment head has shifted and the value of the shift based on the position coordinates. When the shift distance is appropriate, the main control unit 4 receives a feedback signal from the imaging unit 3 to control the ultrasonic transducer 2 to output energy for treatment. By comparing the contours of feature points in the acquired image with the contours of feature points in the calibration values, the interval value between the treatment head and the treatment area is obtained, thereby determining whether the treatment head is in contact with the treatment area during treatment. When the treatment head is in complete contact with the treatment area, the main control unit 4 receives a feedback signal from the imaging unit 3 to control the ultrasonic transducer 2 to output energy for treatment, thus ensuring the treatment effect.

[0050] The application further discloses an ultrasonic therapeutic instrument (not shown in the figure). The ultrasonic therapeutic instrument comprises the ultrasonic therapeutic head, the main machine and the handle, the ultrasonic therapeutic head is detachably connected to the handle, and the ultrasonic therapeutic head is electrically connected to the main machine.

Since the ultrasonic therapeutic instrument adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described here.
