Description

Technical Field

[0001] This disclosure relates to the field of tumor ablation device technology, and in particular to a closed-type anti-proliferation ablation device for tumors. Background Technology

[0002] Tumor ablation therapy is a minimally invasive technique that directly destroys tumor tissue using physical or chemical means, effectively controlling tumor growth and alleviating symptoms. The main methods and their applications are as follows: Radiofrequency ablation: High-frequency current generates heat, causing tumor cell necrosis; suitable for liver cancer, lung cancer, etc. Microwave ablation: Electromagnetic wave heating is more efficient; suitable for larger tumors or tumors near blood vessels. Cryoablation: Low-temperature destruction of cells; safer for tumors near organs, such as prostate cancer. Nanoknife ablation: High-voltage electrical pulses create nanopores to induce apoptosis while preserving blood vessels and nerves; suitable for complex locations such as pancreatic cancer.

[0003] In existing technologies, ultrasound therapy belongs to modern medical physical ablation technology. Its principle is to destroy tumor tissue by using the thermal and mechanical effects generated by high-frequency sound waves. This process uses external treatment and does not require treatment inside the body. However, because the size and location of tumors vary among different patients, and the irradiation area of ​​conventional ultrasound irradiation devices is generally fixed and cannot be adjusted, it affects the comprehensive, precise treatment of the tumor area and the prevention of its spread.

[0016] The technical solution provided in this disclosure may include the following beneficial effects:

[0017] 1. The ultrasonic lamp assembly of the present invention is housed inside the storage layer by inserts and a first spring. Depending on the area to be treated, a fourth motor drives a fourth screw to rotate, causing the top plate to move along the fixed frame, adjusting the initial positions of the first, second, and third square plates. When the first, second, and third square plates are in the middle position, the side inserts can cover all the ultrasonic lamp assemblies after unfolding. When lateral expansion is required, the electric telescopic plates on the second and third square plates unfold and insert into the corresponding sockets, connecting the first, second, and third square plates. Driven by a second electric push rod... The first, second, and third plates can descend synchronously to press against the top of the insertion post, sending out the ultrasonic lamp assembly. The spring telescopic rod extends to maintain connection with the second and third plates. By extending the third and fourth electric push rods inside the first, second, and third plates, the insertion plate can be unfolded and the pressure plate moved outward. The area of ​​contact between the first, second, and third plates and the insertion post can be adjusted according to the treatment area, thereby sending out the corresponding number and range of ultrasonic lamp assemblies. In this way, comprehensive treatment can be carried out on the tumor area, thereby preventing incomplete tumor treatment and subsequent spread.

[0018] 2. Under the premise that the protective strips on both sides move towards the middle, if it is necessary to adjust the position of the upper and lower protective strips, that is, only three or one ultrasonic lamp sets are needed for delivery, the upper and lower protective strips are also pushed forward in the same way, and the first electric push rods on both sides will also pull the excess protective strips outward and gather the protective strips. Because the long rods on the two right angle sides are staggered, there will be no problem of movement interference during movement.

[0019] 3. In this invention, the clamping plate is moved outward by the first electric push rod, which pulls the excess length of the protective strip outward. As the protective strips on both sides move towards the middle, the area enclosed by the protective strip becomes smaller, and the excess length of the protective strip increases. Furthermore, the movement of the vertical rod will drive the telescopic rod to rotate the connecting rod, and the slider will slide upward along the vertical frame, so that the clamping plate is always in the middle position and pulled outward, maintaining the stability of the protective strip after it is pulled out. The movement of the clamping plate is along the movement gap of the protective strip and the elastic rubber strip. The area wrapped by the elastic rubber strip elastically expands and contracts with the change of the area enclosed by the protective strip, so that it can fit against the human skin.

[0020] 4. In this invention, when the ultrasonic treatment area is selected as the ultrasonic lamp group in the middle straight line, that is, the five ultrasonic lamp groups in the middle column will be sent out by the push component for use. At this time, the third motor at the outer end of the left and right moving frame drives the third screw to rotate. The vertical plate moves along the moving frame, which drives the horizontal frame and the long rod to push the vertical column towards the middle. The moving block at the top of the vertical column moves horizontally along the square frame. At this time, the protective strips on both sides move towards the middle. At this time, due to the movement of the vertical column, the long rod at the top and bottom ends moves along the horizontal frame to maintain the connection with the vertical column.

A first motor 14 is fixed to the top of the vertical frame 1, and the output end of the first motor 14 is fixedly connected to the first screw 12.

[0040] Understandably, the first motor 14 drives the first screw 12 to rotate, the mounting frame 13 slides along the vertical groove 11 to adjust the height of the treatment component 3 and the enclosure component 4, and the second motor 17 drives the second screw 16 to rotate, so that the vertical frame 1 moves along the inside of the sliding frame 15 to adjust the lateral position of the treatment component 3 and treat tumors in different locations on the patient's body.

[0041] like Figure 3 , Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments, the treatment component 3 further includes: a frame 32, a fixing bracket 33, a movable block 36, and a first spring 39. The top of the storage layer 31 is fixed with the fixing bracket 33, and a square frame 32 is fixed to the outer bottom ring of the storage layer 31. The top of the vertical column 35 is fixed with the movable block 36, which slides along the inside of the frame 32. Right-angled through-holes 37 are formed on the two sides of the vertical column 35 corresponding to the protective strip 41 protruding from it. The first spring 39 is sleeved on the surface of the insertion post 38. The top and bottom of the first spring 39 are fixedly connected to the insert post 38 and the top of the storage layer 31. The pushing assembly 5 also includes: a top plate 51; a fourth screw 52, ​​a fourth motor 53, and a second electric push rod 54. Side grooves are provided on both sides of the top of the fixing frame 33, and the fourth screw 52 is rotatably installed inside one side groove of the fixing frame 33. The fourth motor 53 is fixed to the outer end of the fixing frame 33, and the output end of the fourth motor 53 is fixedly connected to the fourth screw 52. One side of the top plate 51 is threaded onto the surface of the fourth screw 52. A second electric push rod 54 is fixed at the middle position of the top plate 51 corresponding to the first square plate 56, and the extended end of the second electric push rod 54 is fixedly connected to the first square plate 56. Insert plates 58 are slidably inserted into both ends of the first square plate 56, the second square plate 512, and the third square plate 513, and a third electric push rod 59 is fixed inside the insert plate 58. A pressure plate is fixed to the extended end of the third electric push rod 59. Furthermore, a fourth electric push rod 51 oriented in two directions is fixed inside the first square plate 56, the second square plate 512, and the third square plate 513. 0, and the extended end of the fourth electric push rod 510 is fixedly connected to the insert plate 58. Two electric telescopic plates 511 are fixed to the end of the second square plate 512 and the third square plate 513 facing the first square plate 56. Sockets 57 are fixed to the top two sides of the first square plate 56 and the side of the second square plate 512 away from the first square plate 56. Among them, a spring telescopic rod 55 is fixed to the top plate 51 at the position corresponding to the second square plate 512 and the third square plate 513, and the extended end of the spring telescopic rod 55 is fixedly connected to the second square plate 512 and the third square plate 513.

[0042] Understandably, the ultrasonic lamp assembly 34 is housed inside the storage layer 31 via the insert 38 and the first spring 39. Depending on the area to be treated, the fourth motor 53 drives the fourth screw 52 to rotate, causing the top plate 51 to move along the fixing frame 33, adjusting the initial positions of the first square plate 56, the second square plate 512, and the third square plate 513. When the first square plate 56, the second square plate 512, and the third square plate 513 are in the middle position, the side inserts 58, after unfolding, can cover all the ultrasonic lamp assemblies 34. When lateral expansion is required, the electric telescopic plates 511 on the second square plate 512 and the third square plate 513 unfold and insert into the corresponding sockets 57, connecting the first square plate 56, the second square plate 512, and the third square plate 513. The second electric push rod 5... Driven by 4, the first square plate 56, the second square plate 512, and the third square plate 513 can descend synchronously to press the top of the insertion post 38, sending out the ultrasonic lamp group 34. The spring telescopic rod 55 extends to maintain its connection with the second square plate 512 and the third square plate 513. Through the extension of the third electric push rod 59 and the fourth electric push rod 510 inside the first square plate 56, the second square plate 512, and the third square plate 513, the insertion plate 58 can be unfolded and the pressure plate can be moved outward. The area of ​​the first square plate 56, the second square plate 512, and the third square plate 513 pressing and contacting the insertion post 38 is adjusted according to the treatment area, thereby sending out the corresponding number and range of ultrasonic lamp groups 34. In this way, comprehensive treatment can be carried out on the tumor area, thereby preventing incomplete tumor treatment and subsequent spread.

[0043] like Figure 4 , Figure 5 and Figure 6As shown, in some embodiments, the enclosure assembly 4 further includes: a movable frame 43, a third screw 44, a third motor 45, a vertical frame 1, and a movable notch 410. The movable frame 43 is fixed at the middle position of the four sides of the top of the storage layer 31, and the third screw 44 is rotatably installed inside the movable frame 43. A vertical plate 46 is threaded onto the surface of the third screw 44 and slides along the inside of the movable frame 43. The third motor 45 is fixed to the outer end of the movable frame 43, and the output end of the third motor 45 is fixedly connected to the third screw 44. The bottom four corners of the protective strip 41 are fixedly connected to the elastic rubber strip 42. Movable notches 410 are provided on the four sides adjacent to the elastic rubber strip 42 of the protective strip 41. A horizontal frame 47 is fixed to the bottom of the vertical plate 46, and two long rods 48 are symmetrically slidably installed inside the horizontal frame 47. The other end of the long rod 48 is fixedly connected to the vertical column 35. The long rods 48 on both sides of the right angle surface of the storage layer 31 are fixedly connected to the vertical column 35 in a staggered manner. The bottom of the vertical plate 46 is located on the back of the horizontal frame 47 and a vertical frame 49 is fixedly attached to it. A slider 411 is slidably connected inside the vertical frame 49. Two connecting rods 412 are symmetrically connected to the surface of the slider 411 via a pivot axis. A first telescopic rod 413 is fixed at the bottom of the vertical column 35 corresponding to the other end of the connecting rod 412. The other end of the connecting rod 412 is rotatably connected to the first telescopic rod 413. A first electric push rod 415 is fixed at the bottom of the vertical frame 49. A clamping plate 414 is slidably engaged with the protective belt 41 corresponding to the position of the first electric push rod 415. The extended end of the first electric push rod 415 is fixedly connected to the clamping plate 414. The clamping plate 414 slides inside the moving notch 410.

[0044] It should be noted that after determining the ultrasound treatment area for the tumor location, the third screw 44 inside the corresponding moving frame 43 is rotated in the corresponding direction. For example, with... Figure 4For example, the ultrasonic treatment area is selected as the ultrasonic lamp group 34 in the middle straight line. That is, the five ultrasonic lamp groups 34 in the middle column will be pushed out by the push component 5 for use. At this time, the third motor 45 at the outer end of the left and right moving frames 43 drives the third screw 44 to rotate. The vertical plate 46 moves along the moving frame 43, driving the horizontal frame 47 and the long rod 48 to push the vertical column 35 towards the middle. The moving block 36 at the top of the vertical column 35 moves horizontally along the square frame. At this time, the protective strips 41 on both sides move towards the middle. At this time, due to the movement of the vertical column 35, the long rod 48 at the top and bottom ends moves along the horizontal frame 47 to maintain the connection with the vertical column 35. At the same time, the first electric push rod 415 drives the clamping plate 414 to move outward, pulling the excess length of the protective strip 41 outward. And because the protective strips 41 on both sides move towards the middle, the area enclosed by the protective strip 41 becomes smaller, and the excess length of the protective strip 41 will increase. In addition, the movement of the vertical rod will drive the third screw 44 to rotate. A telescopic rod 413 drives the connecting rod 412 to rotate, and the slider 411 slides upward along the vertical frame 49, so that the clamp 414 is always pulled outward in the middle position, maintaining the stability of the protective belt 41 after it is pulled out. The movement of the clamp 414 is along the movement notch 410 of the protective belt 41 and the elastic rubber belt 42. The wrapping area of ​​the elastic rubber belt 42 elastically expands and contracts with the change of the area enclosed by the protective belt 41, so that it can fit against the human skin. If it is necessary to adjust the position of the upper and lower protective belts 41 when the protective belts 41 on both sides move towards the middle, that is, only three sets or one set of ultrasonic lamps 34 are needed for delivery. The upper and lower protective belts 41 are also pushed forward in the same way, and the first electric push rods 415 on both sides also pull the excess protective belts 41 outward and gather the protective belts 41. Because the long rods 48 on the two right angle sides are staggered, there will be no problem of movement interference during movement.

[0045] Working principle:

[0046] When using the device, the patient lies on the treatment bed 2. The location and extent of the tumor are determined beforehand through medical diagnosis. The first motor 14 drives the first screw 12 to rotate, and the mounting frame 13 slides along the vertical groove 11, adjusting the height of the treatment component 3 and the enclosure component 4. The second motor 17 drives the second screw 16 to rotate, causing the vertical frame 1 to move inside the sliding frame 15, adjusting the lateral position of the treatment component 3. Treatment is then applied to tumors in different locations on the patient's body, allowing the enclosure component 4 to adhere to the patient's skin. Pushing component 5 pushes the treatment component 3 out, initiating ultrasound treatment. The treatment area corresponds to the patient's tumor area. The ultrasonic lamp assembly 34 is housed inside the storage layer 31 via the insert post 38 and the first spring 39. Depending on the area to be treated, the fourth motor 53 drives the fourth screw 52 to rotate, causing the top plate 51 to move along the fixing frame 33, adjusting the initial positions of the first square plate 56, the second square plate 512, and the third square plate 513. When the first square plate 56, the second square plate 512, and the third square plate 513 are in the middle position, the side insert plates 58, after unfolding, can cover all the ultrasonic lamp assemblies 34. When lateral expansion is required, the second... The electrically retractable plates 511 on the square plate 512 and the third-party plate 513 unfold and insert into the corresponding sockets 57, connecting the first square plate 56, the second square plate 512, and the third-party plate 513. Driven by the second electrically driven rod 54, the first square plate 56, the second square plate 512, and the third-party plate 513 can simultaneously descend and press against the top of the insertion post 38, sending out the ultrasonic lamp assembly 34. The spring telescopic rod 55 extends to maintain the connection with the second square plate 512 and the third-party plate 513, passing through the interior of the first square plate 56, the second square plate 512, and the third-party plate 513. The third electric push rod 59 and the fourth electric push rod 510 extend, which can unfold the insert plate 58 and move the pressure plate outward. This adjusts the area where the first square plate 56, the second square plate 512, and the third square plate 513 press against the insert post 38, targeting the treatment area. This then delivers a corresponding number and range of ultrasonic lamps 34. In this way, comprehensive treatment of the tumor area can be performed, preventing incomplete tumor treatment and subsequent spread. After determining the ultrasonic treatment area for the tumor location, the third screw 44 inside the moving frame 43 is rotated in the corresponding direction. For example, with... Figure 4For example, the ultrasonic treatment area is selected as the ultrasonic lamp group 34 in the middle straight line. That is, the five ultrasonic lamp groups 34 in the middle column will be pushed out by the push component 5 for use. At this time, the third motor 45 at the outer end of the left and right moving frames 43 drives the third screw 44 to rotate. The vertical plate 46 moves along the moving frame 43, which drives the horizontal frame 47 and the long rod 48 to push the vertical column 35 towards the middle. The moving block 36 at the top of the vertical column 35 moves horizontally along the square frame. At this time, the protective strips 41 on both sides move towards the middle. At this time, due to the movement of the vertical column 35, the long rod 48 at the top and bottom ends moves along the horizontal frame 47 to maintain the connection with the vertical column 35. At the same time, the clamping plate 414 moves outward through the first electric push rod 415, pulling the excess length of the protective strip 41 outward. As the protective strips 41 on both sides move towards the middle, the area enclosed by the protective strip 41 becomes smaller, and the excess length of the protective strip 41 increases. In addition, the movement of the vertical rod will drive the first telescopic rod 413 to move. The connecting rod 412 rotates, and the slider 411 slides upward along the vertical frame 49, so that the clamp 414 is always pulled outward in the middle position, maintaining the stability of the protective belt 41 after it is pulled out. The clamp 414 moves along the movement notch 410 of the protective belt 41 and the elastic rubber belt 42. The wrapping area of ​​the elastic rubber belt 42 elastically expands and contracts with the change of the area enclosed by the protective belt 41, so that it can fit the human skin. If it is necessary to adjust the position of the upper and lower protective belts 41 when the protective belts 41 on both sides move towards the middle, that is, only three or one sets of ultrasonic lamps 34 are needed for delivery. The upper and lower protective belts 41 are also pushed forward in the same way, and the first electric push rods 415 on both sides also pull the excess protective belts 41 outward and gather the protective belts 41. Because the long rods 48 on the two right angle sides are staggered, there will be no problem of movement interference during movement, thus enabling precise and efficient treatment of the patient's tumor.
