Description

Technical Field

[0001] This invention relates to a focused ultrasound device, and more particularly to a focused ultrasound therapy system and its operating method. Background Technology

[0002] Ultrasound imaging and ultrasound therapy require the establishment of a good acoustic channel, which mainly refers to the space between the ultrasound emitting surface and the patient's skin. This space needs to meet the physical properties of ultrasound propagation and must be free of air, because air reflects ultrasound waves completely.

[0003] Common materials that meet the requirements for ultrasonic propagation include water, latex, and silicone. Water is the best material for achieving fast propagation speed and low attenuation, while other materials exhibit significant reflection and attenuation.

[0004] Common coupling methods in ultrasound therapy include wet coupling and dry coupling.

[0005] Wet coupling involves completely immersing the area of ​​the body that needs treatment in water. Its advantages are that the ultrasound emitting surface and the skin are coupled solely by water, resulting in less attenuation, thorough coupling, and good effects. Its disadvantages are that it is prone to leakage, the water treatment equipment is complex and bulky, and the water sealing operation is laborious and time-consuming.

[0006] Dry coupling involves creating a water-filled bladder using acoustically transparent materials like latex. The ultrasonic emitting surface is then inserted into the bladder, which is then fitted to the skin to construct the ultrasonic channel. Its advantages include leak-proof operation, simplicity, lightweight design, and time-saving. However, its disadvantages include an additional layer of ultrasonic reflection and attenuation, leading to unstable coupling and a higher risk of complications. Summary of the Invention

[0031] The preferred technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: In step two, by repeatedly squeezing and gently heating, the air bubbles between the first connecting surface of the waterproof adhesive ring and the skin are completely squeezed out, ensuring that the waterproof adhesive ring is completely and thoroughly bonded to the skin, so that a sealed area that can accumulate coupling fluid is formed on the inner side of the sac.

[0055] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of the invention.

[0056] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0057] In the description of this invention, it should be noted that the terms "upper," "lower," "front," "rear," "inner," and "outer," etc., indicate the orientation or positional relationship as is the orientation or positional relationship when the product of this invention is used, based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship based on the accompanying drawings, are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0058] Focused ultrasound (HIFU) therapy systems utilize the high-energy sound intensity at the focal zone of the HIFU unit to scan and treat tumor tissue. For example... Figure 1 As shown, it includes an ultrasound transmitting device 100 and a coupling fluid sealing assembly 200 for focused ultrasound. The coupling fluid sealing assembly 200 for focused ultrasound includes a pouch body 1 with openings at both ends and a waterproof adhesive ring 2. The ultrasound transmitting device 100 is disposed on the pouch body 1. The first connecting surface 201 of the waterproof adhesive ring 2 is used to adhere to the patient's skin S; the second connecting surface 202 of the waterproof adhesive ring 2 is bonded to the first end 101 of the pouch body 1, and the second end 102 of the pouch body 1 is tightly connected to the housing 3 of the ultrasound transmitting device 100. Thus, the pouch body 1, the housing 3 of the ultrasound transmitting device 100, and the skin together form a sealed area m that can contain the coupling fluid.

[0059] Compared to wet coupling where the human body is completely immersed in water, this focused ultrasound therapy system uses a capsule 1 to accumulate coupling fluid for wet coupling with the human body. This retains the advantages of using water as the sole coupling medium, resulting in less attenuation, more thorough coupling, and better effects, while overcoming the disadvantages of equipment prone to leakage and having a complex and bulky structure.

[0060] In addition, wet coupling, where the patient's body is completely submerged in water, means that the patient's body is immersed in the coupling fluid throughout the entire process, and the ultrasound treatment system is also completely submerged in the coupling fluid. The spatial relationship between the system, the body, and the coupling container cannot be fully visualized. The coupling device has a large contact area with the body, resulting in many sealing gaps and easy water leakage, which leads to complicated operation and time-consuming treatment.

[0061] The focused ultrasound therapy system provided in this embodiment can perform lateral positioning of the ultrasound transmitting device 100 and the lesion before treatment begins, ensuring that the lesion is covered by the capsule body 1 area. Subsequently, only the lesion position needs to be vertically positioned to determine the angle of ultrasound wave generation. Therefore, the operation is more convenient and time-saving, and the treatment effect is better.

[0062] As can be seen, the focused ultrasound therapy system in this embodiment occupies less space, has a wider range of applications, requires far fewer auxiliary devices, consumes far less coupling fluid, and reduces energy consumption by about 90%. Meanwhile, the sound transmission capability and coupling effect are exactly the same.

[0063] Compared with traditional dry coupling, in this embodiment, the capsule 1 is open and connected to the human body. The capsule 1 is filled with coupling fluid. The ultrasonic emitting surface of the ultrasonic emitting device 100 and the skin are coupled solely by the coupling fluid. There is no barrier between the human skin and the coupling fluid, such as silicone or other sealing film media. This reduces the excess ultrasonic reflection and attenuation surface present in traditional dry coupling, thereby reducing attenuation, ensuring thorough coupling, making the coupling state more stable, and improving the ultrasonic effect.

[0064] It eliminates the attenuation and absorption of ultrasound by the sealing membrane, minimizing the skin damage caused by it. At the same time, due to the direct heat absorption effect of the coupling fluid, the safety is greatly improved for patients undergoing long-term treatment.

[0065] In addition, it avoids the incomplete coupling caused by the evaporation of the coupling fluid outside the capsule wall in dry coupling, as well as the resulting risk of burns. At the same time, it retains the advantages of traditional dry coupling equipment, such as simplicity and flexible operation, which is conducive to the promotion and application of focused ultrasound therapy systems.

[0066] like Figure 1 As shown, the second end 102 of the bag body 1 is connected to the shell 3 through an annular seal 4. Specifically, the inner side of the second end 102 of the bag body 1 and the outer side of the shell 3 are tightly sealed by the annular seal 4.

[0067] The waterproof adhesive ring 2 is a waterproof adhesive material that can adhere tightly to the skin. It is a planar film with a certain thickness, exhibiting good tissue compatibility and water tightness. Depending on the specific needs, it can be manufactured into rings of varying widths and shapes. One side adheres to the skin to prevent the coupling fluid from leaking from the skin surface; the other side adheres to the sac body to prevent the coupling fluid from leaking between the two. The material and function of the waterproof adhesive ring can also be replaced by flexible or semi-flexible devices with skin-adhesive capabilities.

[0068] Preferably, the cross-section of the waterproof adhesive ring 2 is square, circular, or non-coplanar irregular, the lower connecting surface of the waterproof adhesive ring 2 is the first connecting surface 201, the upper connecting surface of the waterproof adhesive ring 2 is the second connecting surface 202, and the end face of the first end 101 of the bag body 1 is in contact with the second connecting surface 202.

[0069] It should be understood that the shape and size of the waterproof adhesive ring 2 can be customized as needed. Its function is to confine a certain amount of coupling liquid to a certain area on the skin surface. The confined coupling liquid can be located on the upper, lower, or side of the skin, serving as a coupling and sound transmission channel between the ultrasound transmitting device and the skin.

[0070] Preferably, the bag body 1 is made of a waterproof film of polymer materials, such as plastic, latex, nanomaterials, etc., and the bag body 1 and the waterproof adhesive ring 2 are connected to form a whole.

[0071] Preferably, the coupling fluid can be water or other sound-permeable liquid.

[0072] like Figure 1 As shown, preferably, the focused ultrasound treatment system further includes a coupling fluid addition / reduction component 10, which can add or remove coupling fluid into the sealed area m enclosed by the bag body 1, the housing 3 of the ultrasound transmitter 100, and the skin.

[0073] like Figure 1 As shown, the ultrasonic transmitting device 100, in addition to the housing 3, also includes an ultrasonic transmitting part 5 having the ultrasonic transmitting surface f, a sealing ring 6, and an ultrasonic imaging head 7.

[0074] The ultrasonic transmitting part 5 has an arc-shaped structure with a central hole, with the concave side facing the patient and the convex side facing away from the patient.

[0075] The concave surface of the ultrasound emitting unit 5 is a focused ultrasound emitting surface. The high-energy ultrasound waves emitted by it propagate through the coupling fluid, penetrate the skin, enter the body tissue, and form a focal point, generating high temperature and high pressure at the focal point. The focal point can be used for lesion treatment when it is located at the lesion site.

[0076] The housing 3 serves as a support for the ultrasonic transmitter 5. The sealing ring 6 is located at the central hole of the ultrasonic transmitter 5 and extends longitudinally to form a columnar body. The sealing ring 6 and the ultrasonic transmitter 5 are tightly fitted together by a sealing ring on the barrel-shaped body.

[0077] The ultrasound imaging head 7 can extend, retract, and rotate within the sealing ring 6 to detect lesions. Specifically, it is equipped with a motor 8, which drives the ultrasound imaging head 7 to move axially or rotate independently, thereby moving closer to or away from the human body.

[0078] like Figure 1 As shown, the housing 3, the ultrasonic emitting part 5, and the sealing ring 6 form a sealed space n that can be inflated or deflated. The sealed space n is located on the concave-convex side of the ultrasonic emitting part 5, and the gas in the sealed space is preferably air.

[0079] Preferably, the focused ultrasound therapy system further includes a pressure regulating component 20, which can adjust the amount of gas in the sealed space n, thereby controlling the pressure acting on the convex surface of the ultrasound emitting part 5.

[0080] It should be noted that the ultrasonic transmitter 5 is generally made of piezoelectric ceramic or polymer resin composite materials, which are therefore fragile, easily deformed, and not very durable, making it prone to damage from impacts or pressure. Moreover, when the ultrasonic transmitter 5 is deformed or damaged, its focusing performance decreases, resulting in a poorer ultrasonic treatment effect and potentially causing skin damage.

[0081] The air pressure increase / decrease component 20 can inflate or depressurize the sealed space, thereby balancing the pressure on the inner and outer surfaces of the ultrasonic transmitter 5 as much as possible, thus reducing its deformation and preventing damage to the ultrasonic transmitter 5 from pressure, as well as preventing surface deformation.

[0082] like Figure 1As shown, preferably, the focused ultrasound therapy system provided in this embodiment includes a pressure sensor 24 and a hydraulic sensor 14. The pressure sensor 24 is disposed in a sealed space to detect the air pressure inside the sealed space n, i.e., the ultrasound emitting part 5; the hydraulic sensor 14 is disposed outside the sealed space, i.e., in the coupling fluid inside the bag body, to detect the hydraulic pressure outside the ultrasound emitting part 5.

[0083] In addition, it also includes a pressure control module 9, which is connected to the air pressure sensor 24, the hydraulic sensor 14, the air pressure increase / decrease component 20 and the coupling fluid increase / decrease component 10 via wires.

[0084] The pressure control module 9 receives pressure data from the air pressure sensor 24 and the hydraulic sensor 14, and controls the air pressure increase / decrease component 20 and the coupling fluid increase / decrease component 10 to increase or decrease the pressure on the inner and outer sides of the ultrasonic transmitter 5.

[0085] More specifically, the pressure control module 9 receives signals from the pneumatic pressure sensor 24 and the hydraulic pressure sensor 14, and compares the differences in their values. Simultaneously, the pressure control module 9 has a program that sets a threshold for the numerical difference. If the difference exceeds the threshold, it controls the pneumatic pressure adjustment component 20 and the coupling fluid adjustment component 10 to adjust the pressure. In this way, the automatic adaptive adjustment of the internal and external pressure of the ultrasonic transmitter 5 is achieved, completing the predetermined pressure increase or decrease, maintaining the balance between the pressure inside the treatment head and the coupling fluid pressure, maintaining the stable shape of the ultrasonic transmitter 5, preventing deformation, and ensuring uniform output of ultrasonic energy.

[0086] like Figure 1 As shown, preferably, the air pressure increase / decrease component 20 includes an air pump 21, an inflation pipe 22, and an exhaust pipe 23. The air pump 21 is connected to the pressure control module 9. The open ends of the inflation pipe 22 and the exhaust pipe 23 extend into the sealed space n.

[0087] Preferably, the coupling fluid addition / reduction assembly 10 includes a liquid pump 11, a filling pipe 12, and a drain pipe 13. One end of the filling pipe 12 and the drain pipe 13 passes through the wall of the annular seal 4 and is connected to the liquid pump 11, while the other open end extends into the bladder body 1 to add or remove coupling fluid in the bladder body 1. The liquid pump 11 is connected to the pressure control module 9 and is controlled by the pressure control module 9 to open and close to achieve filling and draining.

[0088] More preferably, the hydraulic sensor 14 is located near the front end of the filling tube 12 of the ultrasonic transmitter 5. The hydraulic sensor 14 is connected to the pressure control module 9 via a wire, which extends outward through the tube hole of the filling tube 12.

[0089] It should be understood that, in the initial state, one end of the capsule body 1 is sealed and connected to the ultrasonic transmitting device 100, while the other end remains open, and there is no coupling fluid inside the capsule body 1.

[0090] During use, clean the skin of the target area, first roughly position the focused ultrasound treatment system between itself and the patient's body, and position the system in the approximate area where the lesion is located.

[0091] The first connecting surface 201 of the waterproof adhesive ring 2 is flatly attached to the skin of the area as required. Through repeated squeezing and gentle heating, the air bubbles between the first connecting surface 201 of the waterproof adhesive ring 2 and the skin are completely squeezed out, ensuring that the waterproof adhesive ring 2 is completely and thoroughly bonded to the skin, so that a sealed area m that can accumulate coupling fluid is formed on the inside of the bag body 1.

[0092] Then, the coupling fluid is poured into the opening at the other end of the bag body 1 away from the waterproof adhesive ring 2. When it is nearly full, it is tightly fixed to the ultrasonic transmitting device with the annular seal 4. Alternatively, the bag body 1 can be directly and tightly fixed to the ultrasonic transmitting device with the annular seal 4, and then the coupling fluid can be added to the sealed area m through the coupling fluid addition / reduction component 10.

[0093] During this process, the residual gas can be vented and the amount and pressure of the coupling liquid can be adjusted using the drain pipe attached to the ultrasonic transmitter to meet the requirements of ultrasonic transmission.

[0094] At the same time, the air pressure sensor 24 and the hydraulic sensor 14 work, and the air pressure increase and decrease component 20 synchronously fills the sealed space n composed of the housing 3, the ultrasonic emitting part 5 and the sealing ring 6 with air to maintain pressure balance.

[0095] Driven by the motor 8, the ultrasound imaging head 7 moves axially independently, thereby moving closer to or further away from the human body to detect the specific location of the lesion. In turn, the longitudinal position of the ultrasound transmitting device 100 is adjusted to adjust the ultrasound focusing range and angle, so as to achieve effective treatment.

[0096] During the process, the air pressure sensor 24 and the hydraulic sensor 14 remain operational. The air pressure adjustment component 20, together with the coupling fluid adjustment component 10, adjusts the coupling fluid in the sealed area m and the air in the sealed space n to maintain the internal and external pressure balance of the ultrasonic transmitter and protect the ultrasonic transmitter in real time.
