Abstract
Description
Technical Field
[0001] This invention relates to a focused ultrasound device, and more particularly to a focused ultrasound therapy system combined with a semi-dry water bag. Background Technology
[0002] Focused ultrasound is often used to treat uterine fibroids or adenomyosis; however, the intestines often enter in front of the uterus, and the intestines contain gas, which cannot be transmitted by ultrasound, thus seriously interfering with the treatment process.
[0003] The current standard method is as follows: 1. If it is a top-mounted, fully dry water-filled balloon, the pressure is transmitted through the balloon wall to the skin-intestine-uterus by pressing down with the treatment head. The intestine, under pressure, will slide out from the gap between the uterus and the abdominal wall towards the head, thus squeezing the intestine out from the front of the uterus, forming a complete and smooth ultrasound channel through the skin-abdominal wall-uterus for treatment. This method is seen in equipment from companies such as Shenzhen Pro and Wuxi Haiying.
[0004] 2. The under-mounted, fully wet, water-sealed device involves implanting a spherical, sealed water-filled balloon between the treatment head and the skin. As the treatment head rises, pressure is transmitted through the balloon to the skin, intestines, and uterus, thus creating the necessary ultrasound pathway. This method is found in equipment from companies such as Chongqing HIFU and Shanghai Xindi.
[0005] Both methods add a water sac while compressing the intestines. The water sac reflects ultrasound, which can lead to problems such as blurred ultrasound images, damage to the ultrasound imaging probe, deformation or damage to the emitting surface of the treatment head, and skin burns. Summary of the Invention
[0006] Based on the different advantages and disadvantages of the two water-sealing methods mentioned above, this invention provides a focused ultrasound water-filled balloon compression device, which combines a semi-dry water-filled balloon and uses coupling fluid pressure to compress intestinal function, while eliminating the influence of the water-filled balloon wall on the ultrasound channel, thus ensuring the quality of ultrasound images and the safety and integrity of the ultrasound channel.
[0007] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: an ultrasonic coupling water bag protection device, characterized in that it includes a bag body filled with coupling fluid, a support and protection device, and a base;
[0008] The lower opening of the bag body is attached to the patient's skin via a waterproof adhesive ring; the upper opening of the bag body is connected to the base.
[0009] The support and protection device includes a rigid cover with an opening facing the bladder body. The rear end of the cover is connected to the base. The bladder body is placed in the inner cavity of the cover and is used to withstand the reverse pressure of the coupling fluid inside the bladder body, thus limiting the rupture caused by excessive expansion of the bladder body.
[0010] The cover moves in three dimensions following the base. The cover squeezes the bag body, and the coupling fluid inside the bag body squeezes the human body surface to generate pressure, pushing out tissues that are not conducive to the treatment process from the ultrasound channel.

[0020] The lower opening of the bag body is attached to the patient's skin via a waterproof adhesive ring; the upper opening of the bag body is connected to the base.
[0021] The coupling fluid between the energy emitting surface of the treatment head and the skin surface serves as the ultrasound medium, with no capsule wall obstructing the middle;
[0022] The support and protection device includes a rigid cover with an opening facing the bladder body. The rear end of the cover is connected to the base. The bladder body is placed in the inner cavity of the cover and is used to withstand the reverse pressure of the coupling fluid inside the bladder body, thus limiting the rupture caused by excessive expansion of the bladder body.
[0023] The cover moves in three dimensions following the base. The cover squeezes the bag body, and the coupling fluid inside the bag body squeezes and generates pressure on the human body surface, pushing out tissues that are not conducive to the treatment process from the ultrasound channel.
[0024] A further preferred embodiment of the present invention is as follows: the portion of the sac body close to the patient's skin is a thick-walled portion, and the portion away from the patient's skin is a thin-walled portion; the thick-walled portion and the thin-walled portion extend continuously.
[0025] The thickened portion of the wall is used to withstand the pressure of the rising bladder body and maintain the shape of the bladder body;
[0026] The thin-walled portion is tightly attached to the inner wall of the cover to maintain the deformation required for the movement of the ultrasound therapy device;
[0027] Alternatively, the portion of the bag body closest to the patient's skin may be a corrugated tube connected to the thin-walled portion, which expands or retracts as the bag body is squeezed and deformed.
[0028] A further preferred embodiment of the present invention is as follows: the lower end face of the waterproof adhesive ring is adhered to the patient's skin; the lower end of the pouch body is provided with a folded connecting part, the folded connecting part including a lower connecting plane adhered to the upper end face of the waterproof adhesive ring, the lower connecting plane being bent outward after passing through a limiting ring to form an upper connecting plane; the limiting ring is pressed against the upper part of the inner end of the waterproof adhesive ring;
[0029] The upper connecting plane is connected to the lower end of the wall thickness portion; the upper connecting plane guides the water pressure inside the bladder to press against the waterproof adhesive ring.
[0030] A further preferred embodiment of the present invention is that the base is driven by a robotic arm and can perform three-dimensional motion.
[0031] A further preferred embodiment of the present invention is as follows: the treatment head includes a columnar body connected to a base, a shell, and an arc-shaped emitting surface, wherein the columnar body, the shell, and the arc-shaped emitting surface form a sealed air-filled cavity; the columnar body is driven by a first motor to move axially.
[0032] The imaging head is located in the inner hole of the columnar body and can move axially driven by the second motor.
[0033] A further preferred embodiment of the present invention is as follows: the sealed inflation chamber is provided with an inflation pipe and an exhaust pipe that can adjust the internal air pressure; an air pressure sensor is provided on the inflation pipe or the exhaust pipe, and the air pressure sensor is used to detect the air pressure in the sealed inflation chamber.
[0034] The bladder is equipped with an adjustable coupling fluid filling tube and a drain tube. A hydraulic sensor is installed on the filling tube or the drain tube to detect the hydraulic pressure inside the bladder.
[0035] The pressure controller controls the inflation or deflation of the sealed air chamber by detecting the pressure of the air pressure sensor and the hydraulic pressure sensor, so as to regulate the internal and external pressure balance of the arc-shaped firing surface.
[0036] Another subject of the present invention is: an operation method of a focused ultrasound therapy system, characterized by comprising the following specific steps:
[0037] Step 1: Attach the first side of the waterproof adhesive ring to the skin, attach the first end of the capsule body to the second side of the waterproof adhesive ring, and connect the second end of the capsule body to the base; fill the capsule body with coupling fluid, and immerse the treatment head of the ultrasound therapy device in the coupling fluid;
[0038] Step 2: The robotic arm drives the base to perform three-dimensional motion, moving the ultrasound therapy device to the surface of the patient's lesion area.
[0039] Step 3: Start the second motor to drive the ultrasound imaging head to run independently, get close to the skin, and detect the tumor;
[0040] Step 4: Add coupling fluid into the cyst bag. The hydraulic pressure inside the cyst bag increases. Since the thin wall of the cyst bag is tightly attached to the inner wall of the cover, the cover bears the reverse pressure of the coupling fluid inside the cyst bag, limiting the rupture caused by excessive expansion of the cyst bag. The internal pressure of the cyst bag is transmitted towards the human skin, compressing the intestine through the skin-abdominal wall. The intestine moves upward to the abdomen, and the lesion is observed using an ultrasound imaging head. The ultrasound channel for focused ultrasound treatment is then constructed.
[0041] Step 5: After the ultrasound channel is constructed, the ultrasound imaging head guides the robotic arm to make fine adjustments, and the first motor drives the treatment head to move towards the lesion until the ultrasound focal point is accurately positioned within the lesion. Then, the ultrasound imaging head retracts and the treatment is initiated.
[0042] Compared with existing technologies, the advantages of this invention are that the lower end of the capsule is open and fixed to the patient's skin through a waterproof adhesive ring. The capsule is injected with coupling fluid to form an ultrasound channel that provides clearer imaging and lower energy loss. This ultrasound channel uses only a single coupling fluid (such as water) as a medium, eliminating reflection and absorption from the capsule wall and significantly improving energy transmission efficiency. Furthermore, the capsule is covered by a rigid cover to withstand the reverse pressure of the coupling fluid inside the capsule, while also limiting excessive expansion to prevent rupture. In actual use, the base moves the cover to compress the capsule, further pressurizing the coupling fluid inside the capsule against the body surface, pushing out tissues that are detrimental to the treatment process from the ultrasound channel, further ensuring the safety and integrity of the ultrasound channel and reducing energy loss required for treatment.

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.

[0054] This invention can be applied to intra-abdominal tumors such as uterine fibroids and pancreatic cancer. The compression device used in this invention, combined with a semi-dry water-filled balloon, facilitates the external cylindrical support to work in conjunction with intestinal compression, eliminating the influence of the water-filled balloon wall on the ultrasound channel, and ensuring the quality of ultrasound images and the safety and integrity of the ultrasound channel. The specific technical solution is as follows:
[0055] like Figure 1 and Figure 2 As shown, the focused ultrasound therapy system 100 includes a movable base 30 and a sac body 10 filled with coupling fluid s connected to the base 30, a support and protection device 20, and an ultrasound therapy device 50; the ultrasound therapy device 50 includes a treatment head 51 and an imaging head 52; the energy emission surface of the treatment head 51 and the coupling fluid on the skin surface serve as the ultrasound medium.
[0056] The basic structure of the ultrasound coupling water bag protection device 101 consists of the bag body 10 filled with coupling fluid s, the support and protection device 20, and the base 30. In actual use, the lower opening of the bag body 10 is attached to the patient's skin f through a waterproof adhesive ring 40; the upper opening of the bag body 10 is connected to the base 30.
[0057] The support and protection device 20 includes a rigid cover 21 with an opening facing the bladder body. The rear end of the cover 21 is connected to the base 30. The bladder body 10 is placed in the inner cavity of the cover 21 and is used to withstand the reverse pressure of the coupling fluid inside the bladder body 10, thus limiting the rupture caused by excessive expansion of the bladder body 10.
[0058] The cover 21 follows the base 30 in three-dimensional motion. The cover 21 squeezes the bag body 10, and the coupling fluid s inside the bag body 10 squeezes the human body surface to generate pressure, pushing out tissues that are not conducive to the treatment process from the ultrasound channel H.
[0059] The advantages of this invention are that the lower end of the capsule 10 is opened and fixed to the patient's skin f by a waterproof adhesive ring 40. The capsule 10 is injected with coupling fluid s to form an ultrasound channel H that allows for clearer imaging and lower energy loss. Furthermore, the capsule 10 is covered by a rigid cover 21 to withstand the reverse pressure of the coupling fluid s inside the capsule 10, while also limiting the excessive expansion of the capsule 10 to prevent rupture. In actual use, the base drives the cover 21 to move and squeeze the capsule 10, further squeezing the coupling fluid s inside the capsule 10 against the human body surface to generate pressure, pushing out tissues that are not conducive to the treatment process from the ultrasound channel H, further ensuring the safety and integrity of the ultrasound channel H and reducing the energy loss required for treatment.
[0060] Preferably, in this embodiment, the portion of the pouch body 10 closest to the patient's skin is the thick-walled portion 12, and the portion furthest from the patient's skin is the thin-walled portion 11; the thick-walled portion 12 and the thin-walled portion 11 extend continuously and transition naturally.
[0061] The thick-walled portion 12 is used to withstand the increased pressure of the capsule 10 and maintain the shape of the capsule 10. The thin-walled portion 11 is in close contact with the inner wall of the cover 21 to maintain the deformation required for the movement of the ultrasound therapy device.
[0062] Specifically, in practical use, to improve the flexibility and range of motion of the pouch body 10 in the area approaching the patient's skin, the cover 21 does not completely cover the entire pouch body 10. Therefore, the lower part of the pouch body 10, which is not covered by the cover 21, needs to be made with a thicker wall structure to withstand the pressure of the coupling fluid s on the pouch wall without excessive deformation or rupture. Furthermore, the thicker portion of the pouch body 10 does not lose its flow characteristics, allowing the pouch body 10 to compress the patient's skin f.
[0063] Another option, such as Figure 7 As shown, the portion of the bag body 10 closest to the patient's skin is a corrugated tube 12'. The corrugated tube 12' can expand or retract as the bag body 10 is squeezed and deformed, thereby improving the flexibility and range of motion of the area of the bag body 10 closest to the patient's skin.
[0064] like Figure 1 and Figure 5As shown, the lower end face of the waterproof adhesive ring 40 is adhered to the patient's skin f. To ensure a more secure connection between the pouch body 10 and the waterproof adhesive ring 40, a folded connecting part c is provided at the lower end of the pouch body 10. Specifically, the folded connecting part c includes a lower connecting plane c1 adhered to the upper end face of the waterproof adhesive ring 40, and the lower connecting plane c1 is bent outwards through a restricting ring c2 to form an upper connecting plane c3. At this time, the restricting ring c2 presses against the upper part of the inner end of the waterproof adhesive ring 40, and the upper connecting plane c3 is connected to the lower end of the wall thickness portion 12. The upper connecting plane c3 guides the water pressure inside the pouch body 10 to press against the waterproof adhesive ring 40. The folded connecting part c allows the restricting ring c2 to more securely fix the lower end of the pouch body 10 to the waterproof adhesive ring 40.
[0065] Preferably, the base 30 of the focused ultrasound therapy system 100 is driven by the robotic arm 102 and can perform three-dimensional motion. Specifically, the treatment head 51 includes a cylindrical body a1, a housing a2, and an arc-shaped emitting surface a3 connected to the base 30. The cylindrical body a1, housing a2, and arc-shaped emitting surface a3 form a sealed air-filled cavity a4. The cylindrical body a1 is driven axially by a first motor b1. The imaging head 52 is disposed in the inner hole of the cylindrical body a1 and is driven axially by a second motor b2.
[0066] like Figure 1 and Figure 6 As shown, the sealed inflation chamber a4 is equipped with an inflation pipe e1 and an exhaust pipe e2 that can adjust the internal air pressure; an air pressure sensor e3 is provided on the inflation pipe e1 or the exhaust pipe e2 to detect the air pressure in the sealed inflation chamber a4.
[0067] The pouch body 10 is equipped with an adjustable coupling fluid filling pipe 13 and a drain pipe 14. A hydraulic sensor 15 is installed on the filling pipe 13 or the drain pipe 14 to detect the hydraulic pressure inside the pouch body 10. The pressure controller controls the filling pipe e1 or the exhaust pipe e2 to fill or exhaust the sealed air cavity a4 by detecting the pressure of the air pressure sensor e3 and the hydraulic sensor 15, so as to adjust the internal and external pressure balance of the arc-shaped emission surface a3.
[0068] In actual treatment, the operation method of the focused ultrasound therapy system includes the following specific steps:
[0069] Step 1: As Figure 1 and Figure 5As shown, the first surface t1 of the waterproof adhesive ring 40 is adhered to the skin f, and the first end d1 of the capsule body 10 is adhered to the second surface t2 of the waterproof adhesive ring 40. The second end d2 of the capsule body 10 is connected to the base 30. The capsule body 10 is filled with coupling fluid s, and the treatment head 51 of the ultrasound therapy device 50 is immersed in the coupling fluid s. This forms an ultrasound channel H between the treatment head 51 and the lesion v. Since there is no capsule wall obstructing the connection between the bottom of the capsule body 10 and the patient's skin f, this optimized ultrasound channel H allows for clearer ultrasound imaging and reduces treatment energy loss.
[0070] Step 2: Then, the robotic arm 102 is operated to drive the base 30 to perform three-dimensional motion, further moving the ultrasound treatment device 50 to the surface of the patient's lesion v.
[0071] Step 3: Then start the second motor b2 to drive the ultrasound imaging head 52 to run independently, bring the ultrasound imaging head 52 close to the skin and form an ultrasound image to find the location and shape of the tumor.
[0072] Step 4: Coupling fluid s is added into the pouch body 10 through the filling tube 13, thereby increasing the hydraulic pressure within the pouch body 10. Since the thin-walled portion 11 of the pouch body 10 is tightly attached to the inner wall of the cover 21, the cover 21 bears the reverse pressure of the coupling fluid s within the pouch body 10, preventing rupture caused by excessive expansion of the pouch body 10. Under the constraint of the cover 21, the internal pressure of the pouch body 10 is transmitted towards the human skin f, compressing the intestine g via the skin-abdominal wall and causing the intestine g to move upwards to the abdomen to avoid the lesion v. Then, the lesion v is further observed using the ultrasound imaging head 52. At this point, the ultrasound channel H for focused ultrasound therapy is completed.
[0073] Step 5: After completing the construction of the ultrasound channel H, the ultrasound imaging head 52 retracts, and the first motor b1 drives the treatment head 51 to move towards the lesion v until the ultrasound focal point is within the lesion v, and the treatment is started.
[0074] The main focus of this invention is to illustrate that the lower end of the capsule body 10 is opened and fixed to the patient's skin f through a waterproof adhesive ring 40. The capsule body 10 is injected with coupling fluid s to form an ultrasound channel H that allows for clearer imaging and lower energy consumption. Furthermore, the capsule body 10 is covered by a rigid cover 21 to withstand the reverse pressure of the coupling fluid s inside the capsule body 10, while also limiting excessive expansion of the capsule body 10 to prevent rupture. In actual use, the base drives the cover 21 to move and compress the capsule body 10, further compressing the coupling fluid s inside the capsule body 10 against the human body surface to generate pressure, pushing out tissues that are detrimental to the treatment process from the ultrasound channel H, further ensuring the safety and integrity of the ultrasound channel H and reducing the energy consumption required for treatment.
