Description

Technical Field

[0001] This invention relates to the field of tumor treatment technology, specifically a thermotherapy device for interventional tumor treatment. Background Technology

[0002] Oncology, like internal medicine, surgery, obstetrics and gynecology, and pediatrics, is a secondary discipline in clinical medicine. It is divided into medical oncology, radiation oncology, and surgical oncology. Medical oncology primarily treats various benign and malignant tumors; radiation oncology focuses on radiation therapy; and surgical oncology provides comprehensive treatment, primarily surgery. Specialized oncology hospitals may further subdivide these departments based on different tumor sites. For example, medical oncology may include gastrointestinal oncology and lymphoma oncology; surgical oncology may include breast surgery, head and neck surgery, thoracic surgery, gynecologic oncology, and abdominal surgery. Within medical oncology, adjuvant therapy devices are often used to support patients after radiotherapy.

[0003] There are various treatment methods for tumors, among which hyperthermia is an adjunctive treatment. Existing hyperthermia machines directly fix the hyperthermia site to the lesion side of the patient. However, the distribution of tumors is also diverse. Some tumors are concentrated in a certain area, while others are very large, with a wide cross-section of the tumor. Therefore, traditional hyperthermia methods treat a very broad range, which either easily leads to a large waste of drugs or makes it difficult to concentrate and accurately treat the tumor, resulting in limited treatment effects. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, the present invention provides a tumor interventional hyperthermia device. Through the cooperation of the driving component and the propulsion component, the first and second hyperthermia mechanisms can be quickly positioned. The first and second hyperthermia mechanisms are characterized by precision, adjustability, automatic hyperthermia, automatic massage, and a wide range of hyperthermia, respectively. They are suitable for diverse tumor treatments, eliminate drug waste, enable concentrated and precise treatment, and greatly improve the effect of hyperthermia during tumor treatment, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A tumor interventional hyperthermia device includes a central gate, on which a drive member is provided for rotating the hyperthermia device, and on which a propulsion member is provided for pushing the hyperthermia device closer to the patient's hyperthermia position. The propulsion member is provided with a first hyperthermia mechanism and a second hyperthermia mechanism for hyperthermia, wherein the first hyperthermia mechanism and the second hyperthermia mechanism are vertically distributed between them, and the first hyperthermia mechanism and the second hyperthermia mechanism can be switched to turn towards the patient's hyperthermia side by means of the switching of the propulsion member.

[0007] The first thermotherapy unit consists of a multi-thermal therapy ring assembly, a hot gas connection assembly, and a first gas delivery assembly. The multi-thermal therapy ring assembly is a multi-layered ring structure used to release the hot gas required for thermotherapy, and the inner diameter of the ring structure increases progressively. The hot gas connection assembly is disposed on the multi-thermal therapy ring assembly and is used to connect the hot gas. The multi-thermal therapy ring assembly is symmetrically distributed vertically and horizontally. The first gas delivery assembly is located at the bottom of the multi-thermal therapy ring assembly and is used to deliver the hot gas.

[0008] The second heat therapy mechanism consists of a swinging component, a hot pressing component, and a second air supply component. The swinging component has a reciprocating swinging tendency to increase the heat therapy range. The hot pressing component is located inside the swinging component and is used to massage the heat therapy area and deliver hot air. The second air supply component is located at the bottom of the hot pressing component and is used to deliver hot air.

[0009] As a further embodiment of the present invention, the driving component comprises a drive motor, a drive gear, and a driven gear ring. The drive motor is fixedly connected to one outer wall of the central door by screws, and the drive gear is fixedly connected to the output shaft of the drive motor. The driven gear ring meshes with the teeth of the drive gear and is rotatably connected to the other inner wall of the central door. By rotating the drive gear driven by the drive motor, the rotation of the driven gear ring can be controlled, thereby adjusting the rotation of the first and second heat therapy mechanisms around the axis of the driven gear ring, creating conditions for the heat therapy mechanisms to approach the patient.

[0010] As a further embodiment of the present invention, the propulsion component includes a fixed seat fixedly connected to the outer wall of one side of the driven gear ring by screws, a servo guide rail fixedly connected to the outer wall of one side of the fixed seat by screws for adjusting the distance between the first and second heat therapy mechanisms and the patient, a positioning frame fixedly connected to the slider inside the servo guide rail, a rotary cylinder fixedly connected to the inner wall of the bottom of the positioning frame for adjusting the orientation of the first and second heat therapy mechanisms, and a switching head fixedly connected to the output shaft of the rotary cylinder for fixing the first and second heat therapy mechanisms. The distance between the first or second heat therapy mechanism and the patient can be adjusted by moving the slider inside the servo guide rail, maintaining a suitable distance for heat therapy. Furthermore, the first and second heat therapy mechanisms can be switched to the side closer to the patient by rotating the switching head 180° using the rotary cylinder.

[0011] As a further embodiment of the present invention, the multi-heat therapy ring assembly comprises a heat pressure shroud, a propulsion cylinder, a heat therapy cylinder, a primary heat therapy ring, a secondary heat therapy ring, a tertiary heat therapy ring, and heat nozzles. The heat pressure shroud is fixedly connected to one side of the outer wall of the switching head. The propulsion cylinder is fixedly connected to one narrow-mouth outer wall of the heat pressure shroud. The heat therapy cylinder is fixedly connected to the piston rod of the propulsion cylinder. The primary heat therapy ring is fixedly connected to the outer wall of the heat therapy cylinder. The inner wall of the primary heat therapy ring is provided with equally spaced pipes, and the primary heat therapy ring and the heat therapy cylinder are connected by pipes. The secondary heat therapy ring is located on one side of the primary heat therapy ring, and the tertiary heat therapy ring is located on one side of the secondary heat therapy ring. Four sets of heat nozzles are equally spaced on one side of the outer wall of the heat therapy cylinder, the primary heat therapy ring, the secondary heat therapy ring, and the tertiary heat therapy ring. By pushing the cylinder to move the heat therapy cylinder, the primary heat therapy ring can be moved closer to the secondary heat therapy ring, and then the secondary heat therapy ring can be controlled to move closer to the tertiary heat therapy ring. This process can adjust the heat therapy range. The larger the range, the more heat nozzles are used, and vice versa. In this way, the appropriate size heat therapy rings can be selected and combined for heat therapy.

[0012] As a further embodiment of the present invention, the hot air connection assembly comprises an I-beam plate, an air inlet pipe, an air inlet hole, a sealing ring, a fixing pipe, a telescopic ball column, a spring, and a limiting plate. The I-beam plate includes two sets, respectively fixedly connected to the outer walls of the secondary and tertiary heat therapy rings on the other side. The air inlet pipe is disposed on one outer wall of the I-beam plate, and the air inlet hole is opened on the inner wall of the I-beam plate and communicates with the inner wall of the air inlet pipe. The sealing ring is adhered to the inner wall of the air inlet hole. The fixing pipe includes two sets, respectively fixedly connected to the outer walls of the primary and secondary heat therapy rings on the other side. The telescopic ball column is slidably connected to the inner wall of one end of the fixing pipe. The size of the telescopic ball column is adapted to the size of the air inlet hole. The spring is fixedly connected to the telescopic ball column and the fixing pipe to increase the telescopicity of the telescopic ball column. The limiting plate includes two plates respectively fixed to both ends of the I-beam plate to limit the maximum movable length of the fixing pipe. Taking the hot air connection assembly between the primary and secondary heat therapy rings as an example, when the propulsion cylinder pushes the heat therapy cylinder to move the primary heat therapy ring, the fixed tube will bring the telescopic ball column close to the air inlet. Since the spring is in a compressed state at this time, it can control one end of the telescopic ball column to adhere to the inner wall of the I-beam plate, so that the hot air cannot be discharged from the telescopic ball column. After the telescopic ball column moves into the air inlet, it is sealed by the sealing ring. The hot air will enter the secondary heat therapy ring in sequence from the primary heat therapy ring, the fixed tube, the telescopic ball column, and the air inlet tube, thereby expanding the range of heat therapy. Similarly, when the propulsion cylinder moves forward, the secondary and tertiary heat therapy rings can also complete the gas connection. When the piston rod of the propulsion cylinder is reset, the primary and secondary heat therapy rings will also be reset.

[0013] As a further embodiment of the present invention, the first gas delivery assembly includes a gas delivery pipe fixedly connected to the outer wall of one end of the heat therapy cylinder, and a solenoid valve installed on the outer wall of the gas delivery pipe. One end of the gas delivery pipe is connected to a nebulizer with a heating function. After the solenoid valve is opened, the nebulizer delivers the heated fumigation medicine into the gas delivery pipe, which then enters the heat therapy cylinder for heating.

[0014] As a further embodiment of the present invention, the swing assembly comprises a mounting frame, a servo motor, a connecting rod, a connecting rod, a swing frame, a sliding column, a spring, and a swing cover. The mounting frame is fixedly connected to one outer wall of the switching head, and the servo motor is fixedly connected to the top outer wall of the mounting frame by screws. The connecting rod is fixedly connected to the output shaft of the servo motor. The connecting rod is rotatably connected to the top outer wall of the connecting rod. The inner wall of the swing frame is rotatably connected to one end of the outer wall of the connecting rod, and the bottom outer wall of the swing frame is rotatably connected to the bottom inner wall of the mounting frame. The sliding column is slidably connected inside the sleeve at the top of the mounting frame. The spring is fixedly connected between the mounting frame and the sliding column. The swing cover is welded to one end of the outer wall of the sliding column. When the output shaft of the servo motor rotates, the connecting rod rotates, thereby controlling the swing of the connecting rod, which in turn drives the swing frame to swing, causing the swing cover to swing back and forth. Furthermore, with the compensation effect of the spring, it can be ensured that the swing cover remains as close as possible to the patient's heat therapy side during the swing process.

[0015] As a further embodiment of the present invention, the hot pressing assembly includes a second servo motor fixedly connected to the outer wall of the top of the swing cover, a heat exchanger cylinder fixedly connected to the output shaft of the second servo motor, a central column welded to the inner wall of the top of the heat exchanger cylinder, plugs evenly distributed around the outer wall of the central column, vent holes evenly distributed around the outer wall of the heat exchanger cylinder, and ball plugs slidably connected to the inner wall of the vent holes. The number of ball plugs is the same as the number of plugs. A hot air chamber is disposed between the heat exchanger cylinder and the central column for the circulation of hot air. When the second servo motor drives the heat exchanger cylinder to rotate, it drives the ball plugs of each layer to rotate. As the swing cover swings back and forth, the ball plugs will sequentially contact the patient's body. On the one hand, the rolling of the ball plugs on the patient provides a massage function; on the other hand, the ball plugs are compressed under force, creating gaps between the ball plugs and the vent holes, allowing hot air to pass through these gaps and blow towards the patient for heat therapy.

[0016] As a further embodiment of the present invention, the second gas delivery assembly includes a second gas delivery pipe rotatably connected to the center of the outer wall at the bottom of the heating mesh cylinder, and a second solenoid valve installed on the outer wall of the second gas delivery pipe. One end of the second gas delivery pipe is fixedly connected to the first gas delivery pipe. After the second gas delivery pipe is opened, the nebulizer delivers the heated fumigation medicine through the first gas delivery pipe to the second gas delivery pipe, and then delivers it to the hot air chamber inside the heating mesh cylinder. Finally, the medicine is discharged through the gap between the bulb plug and the vent hole and blown towards the patient for heat therapy.

[0017] As a further embodiment of the present invention, a patient access component is provided at the bottom of the central door. The patient access component includes a base frame disposed on both sides of the central door, a guide rod fixedly connected to the inner walls of both sides of the base frame, and a bed body slidably connected to the outer wall of the guide rod.

[0018] The outer walls on both sides of the central door are welded with a front cover and a rear cover, and a guide rod passes through the interior of the front cover, the central door, and the rear cover. Before the hyperthermia treatment, the patient needs to lie on the bed, and then the medical staff will push the bed into the interior of the front cover and the rear cover. After the positions of the first hyperthermia unit and the second hyperthermia unit are adjusted, the hyperthermia treatment can be directed at the patient's tumor location.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The tumor interventional hyperthermia device of the present invention, through the cooperation of the driving component and the propulsion component, can quickly position the first hyperthermia mechanism and the second hyperthermia mechanism. The first hyperthermia mechanism and the second hyperthermia mechanism are respectively characterized by precision, adjustability, automatic hyperthermia, automatic massage and wide hyperthermia range. It is suitable for diverse tumor treatments, eliminates drug waste, enables concentrated and precise treatment, and greatly improves the effect of hyperthermia in tumor treatment.

[0021] 2. In the tumor interventional hyperthermia device of the present invention, in the first and second hyperthermia mechanisms, under the heating effect of the gas supply pipe of the first gas supply assembly, the hyperthermia cylinder is driven by the propulsion cylinder in the multi-hyperthermia ring assembly to sequentially drive the first-level hyperthermia ring to approach the second-level hyperthermia ring and then to approach the third-level hyperthermia ring. During this process, the telescopic ball column moves to the gas inlet, and the hot air can be connected and unblocked, thereby adjusting the hyperthermia range. The larger the range, the more heat nozzles are used, and vice versa. By analogy, hyperthermia rings of appropriate size can be selected and combined for hyperthermia. It has the characteristics of precision and adjustability, plays an important role in tumor interventional hyperthermia, and is suitable for hyperthermia of patients with concentrated tumor distribution.

[0022] 3. In the tumor interventional hyperthermia device of the present invention, under the heating effect of the second gas supply pipe of the second gas supply assembly, when the second hyperthermia device is switched to the side closer to the patient, the output shaft of the servo motor in the swing assembly rotates, realizing the swinging cover swinging back and forth. At the same time, the heat mesh cylinder is driven to rotate by the servo motor. As the swinging cover swings back and forth, the ball plug will contact the patient's body in turn. On the one hand, the ball plug can achieve the function of massage by rolling on the patient's body. On the other hand, at this time, the ball plug is squeezed by force, and a gap will be generated between the ball plug and the vent hole. Hot air can pass through the gap and blow to the patient for hyperthermia. It has the characteristics of automatic hyperthermia, automatic massage and wide hyperthermia range, and is suitable for hyperthermia of some patients with long tumor cross sections.

[0037] Please see Figure 1-3 In this embodiment of the invention, a tumor interventional hyperthermia device includes a central door 1. The central door 1 is provided with a driving member 2 for rotating the hyperthermia device, and the driving member 2 is provided with a propulsion member 3 for pushing the hyperthermia device closer to the patient's hyperthermia position. The propulsion member 3 is provided with a first hyperthermia mechanism 4 and a second hyperthermia mechanism 5 for hyperthermia. The first hyperthermia mechanism 4 and the second hyperthermia mechanism 5 are vertically distributed between each other, and the first hyperthermia mechanism 4 and the second hyperthermia mechanism 5 can be switched to the patient's hyperthermia side by switching the propulsion member 3.

[0038] Through the cooperation of the driving component 2 and the propulsion component 3, the first thermotherapy unit 4 and the second thermotherapy unit 5 can be quickly positioned. The first thermotherapy unit 4 and the second thermotherapy unit 5 are respectively characterized by precision and adjustability, as well as automatic thermotherapy, automatic massage and wide thermotherapy range. They are suitable for diverse tumor treatments, eliminate drug waste, and enable concentrated and precise treatment, which greatly improves the effect of thermotherapy during tumor treatment.

[0039] Please see Figure 4-5In this embodiment of the invention, the first thermotherapy mechanism 4 is composed of a multi-thermal therapy ring assembly 41, a hot gas connection assembly 42, and a first gas delivery assembly 43. The multi-thermal therapy ring assembly 41 is a multi-layered ring structure used to release the hot gas required for thermotherapy, and the inner diameter of the ring structure increases progressively. The hot gas connection assembly 42 is disposed on the multi-thermal therapy ring assembly 41 for connecting the hot gas, and the multi-thermal therapy ring assembly 41 is symmetrically distributed vertically and horizontally. The first gas delivery assembly 43 is located at the bottom of the multi-thermal therapy ring assembly 41 for delivering hot gas.

[0040] In the first hyperthermia unit 4, under the heating effect of the gas supply pipe 431 of the first gas supply assembly 43, the hyperthermia cylinder 413 in the multi-hyperthermia ring assembly 41 can be driven by the propulsion cylinder 412 in the multi-hyperthermia ring assembly 41 to sequentially drive the first-level hyperthermia ring 414 to approach the second-level hyperthermia ring 415 and then to approach the third-level hyperthermia ring 416. During this process, the telescopic ball column 426 is moved into the air inlet 423, and the hot air can be connected and unblocked, thereby adjusting the hyperthermia range. The larger the range, the more heat nozzles 417 are used, and vice versa. By analogy, hyperthermia rings of appropriate size can be selected and combined for hyperthermia. It has the characteristics of precision and adjustability, plays an important role in hyperthermia for tumor intervention, and is suitable for hyperthermia of patients with concentrated tumor distribution.

[0041] Please see Figure 8 In this embodiment of the invention, the second heat therapy mechanism 5 is composed of a swing component 51, a hot pressure component 52, and a second air delivery component 53. The swing component 51 has a reciprocating swing tendency to increase the heat therapy range. The hot pressure component 52 is disposed inside the swing component 51 and is used to massage the heat therapy area and deliver hot air. The second air delivery component 53 is disposed at the bottom of the hot pressure component 52 and is used to deliver hot air.

[0042] In the second hyperthermia unit 5, under the heating effect of the second gas supply pipe 531 of the second gas supply assembly 53, when the second hyperthermia unit 5 switches to the side closer to the patient, the swing cover 518 swings back and forth by rotating the output shaft of the servo motor 512 in the swing assembly 51. At the same time, the heat mesh cylinder 522 is driven to rotate by the servo motor 521. As the swing cover 518 swings back and forth, the ball plug 526 will come into contact with the patient's body in turn. On the one hand, the ball plug 526 can achieve the function of massage by rolling on the patient's body. On the other hand, the ball plug 526 is squeezed at this time, and a gap will be generated between the ball plug 526 and the vent 525. Hot air can pass through the gap and blow to the patient for hyperthermia. It has the characteristics of automatic hyperthermia, automatic massage and wide hyperthermia range, and is suitable for hyperthermia of some patients with long tumor cross sections.

[0043] Please see Figure 1-2In this embodiment of the invention, the driving component 2 is composed of a driving motor 21, a driving gear 22, and a driven gear ring 23. The driving motor 21 is fixedly connected to the outer wall of one side of the central door 1 by screws, and the driving gear 22 is fixedly connected to the output shaft of the driving motor 21. The driven gear ring 23 meshes with the teeth of the driving gear 22 and is rotatably connected to the inner wall of the other side of the central door 1.

[0044] By driving the drive gear 22 to rotate via the drive motor 21, the driven gear ring 23 can be controlled to rotate, thereby adjusting the first heat therapy mechanism 4 and the second heat therapy mechanism 5 to rotate around the axis of the driven gear ring 23, which can create conditions for the heat therapy mechanism to approach the patient.

[0045] Please see Figure 3 In this embodiment of the invention, the propulsion component 3 includes a fixed base 31 fixedly connected to the outer wall of one side of the driven gear ring 23 by screws, a servo guide rail 32 fixedly connected to the outer wall of one side of the fixed base 31 by screws for adjusting the distance between the first heat therapy mechanism 4 and the second heat therapy mechanism 5 and the patient, a positioning frame 33 fixedly connected to the slider inside the servo guide rail 32, a rotary cylinder 34 fixedly connected to the bottom inner wall of the positioning frame 33 for adjusting the orientation of the first heat therapy mechanism 4 and the second heat therapy mechanism 5, and a switching head 35 fixedly connected to the output shaft of the rotary cylinder 34 for fixing the first heat therapy mechanism 4 and the second heat therapy mechanism 5.

[0046] The distance between the first heat therapy unit 4 or the second heat therapy unit 5 and the patient can be adjusted by moving the slider inside the servo guide rail 32, so as to maintain a suitable distance for heat therapy. On this basis, the first heat therapy unit 4 and the second heat therapy unit 5 can be switched to the side closer to the patient by using the rotary cylinder 34 to drive the switching head 35 to rotate 180°.

The heat pressure cover 411 is fixedly connected to one side of the outer wall of the switching head 35, the propulsion cylinder 412 is fixedly connected to the narrow outer wall of one end of the heat pressure cover 411, the heat therapy cylinder 413 is fixedly connected to the piston rod of the propulsion cylinder 412, and the primary heat therapy ring 414 is fixedly connected to... On the outer wall of the heat therapy cylinder 413, the inner wall of the primary heat therapy ring 414 is provided with pipes that are evenly distributed, and the primary heat therapy ring 414 and the heat therapy cylinder 413 are connected by pipes. The secondary heat therapy ring 415 is provided on one side of the primary heat therapy ring 414, and the tertiary heat therapy ring 416 is provided on one side of the secondary heat therapy ring 415. The heat nozzles 417 include four sets, which are evenly distributed on one side of the outer wall of the heat therapy cylinder 413, the primary heat therapy ring 414, the secondary heat therapy ring 415 and the tertiary heat therapy ring 416 respectively.

[0048] By pushing the cylinder 412 to drive the heat therapy cylinder 413, the primary heat therapy ring 414 can be moved closer to the secondary heat therapy ring 415, thereby controlling the secondary heat therapy ring 415 to move closer to the tertiary heat therapy ring 416. This process can adjust the heat therapy range. The larger the range, the more heat nozzles 417 are used, and vice versa. In this way, the appropriate size of heat therapy rings can be selected and combined for heat therapy.

[0049] Please refer to 6. In this embodiment of the invention, the hot air connection assembly 42 is composed of an I-beam plate 421, an air inlet pipe 422, an air inlet hole 423, a sealing ring 424, a fixing pipe 425, a telescopic ball column 426, a spring 427, and a limiting plate 428. The I-beam plate 421 includes two sets, respectively fixedly connected to the outer wall of the secondary heat therapy ring 415 and the tertiary heat therapy ring 416 on the other side. The air inlet pipe 422 is disposed on one outer wall of the I-beam plate 421. The air inlet hole 423 is opened on the inner wall of the I-beam plate 421 and communicates with the inner wall of the air inlet pipe 422. The sealing ring 424... 24 is adhered to the inner wall of the air inlet 423. The fixing tube 425 includes two sets, which are respectively fixedly connected to the outer wall of the other side of the primary heat therapy ring 414 and the secondary heat therapy ring 415. The telescopic ball column 426 is slidably connected to the inner wall of one end of the fixing tube 425. The size of the telescopic ball column 426 is adapted to the size of the air inlet 423. The spring 427 is fixedly connected to the telescopic ball column 426 and the fixing tube 425 to increase the telescopicity of the telescopic ball column 426. The limiting plate 428 includes two parts, which are respectively fixed to the two ends of the I-plate 421 to limit the maximum movable length of the fixing tube 425.

[0050] Taking the hot air connection assembly 42 between the primary heat therapy ring 414 and the secondary heat therapy ring 415 as an example, when the propulsion cylinder 412 pushes the heat therapy cylinder 413 to move the primary heat therapy ring 414, the fixed tube 425 will bring the telescopic ball column 426 close to the air inlet 423. Since the spring 427 is in a compressed state at this time, it can control one end of the telescopic ball column 426 to adhere to the inner wall of the I-beam plate 421, so that the hot air cannot be discharged from the telescopic ball column 426. When the telescopic ball column 426 moves to the air inlet... After entering the hole 423, the sealing ring 424 seals the space, and the hot air will sequentially enter the secondary heat therapy ring 415 from the primary heat therapy ring 414, the fixed tube 425, the telescopic ball column 426, and the air inlet tube 422, thereby expanding the range of heat therapy. Similarly, when the push cylinder 412 moves forward, the secondary heat therapy ring 415 and the tertiary heat therapy ring 416 can also complete the gas connection. When the piston rod of the push cylinder 412 is reset, the primary heat therapy ring 414 and the secondary heat therapy ring 415 will also be reset.

[0051] Please see Figure 5 In this embodiment of the invention, the first gas delivery component 43 includes a gas delivery pipe 431 fixedly connected to the outer wall of one end of the heat therapy cylinder 413, and a solenoid valve 432 installed on the outer wall of the gas delivery pipe 431, wherein one end of the gas delivery pipe 431 is connected to an atomizer with a heating function.

[0052] After the solenoid valve 432 is opened, the nebulizer will deliver the heated fumigation medicine into the air supply pipe 431, and then into the heat therapy cylinder 413 for heating.

[0053] Please see Figure 8-9 In this embodiment of the invention, the swing assembly 51 is composed of a mounting frame 511, a first servo motor 512, a first connecting rod 513, a second connecting rod 514, a swing frame 515, a sliding column 516, a second spring 517, and a swing cover 518. The mounting frame 511 is fixedly connected to one outer wall of the switching head 35, and the first servo motor 512 is fixedly connected to the top outer wall of the mounting frame 511 by screws. The first connecting rod 513 is fixedly connected to the first servo motor 512. On the output shaft, connecting rod 2 514 is rotatably connected to the top outer wall of connecting rod 1 513, the inner wall of swing frame 515 is rotatably connected to the outer wall of one end of connecting rod 2 514, and the bottom outer wall of swing frame 515 is rotatably connected to the bottom inner wall of mounting frame 511. Sliding column 516 is slidably connected to the sleeve at the top of mounting frame 511. Spring 2 517 is fixedly connected between mounting frame 511 and sliding column 516. Swing cover 518 is welded to the outer wall of one end of sliding column 516.

[0054] When the output shaft of servo motor 512 rotates, connecting rod 513 will rotate, which in turn controls connecting rod 514 to swing, which in turn drives swing frame 515 to swing, causing swing cover 518 to swing back and forth. Under the compensation of spring 517, it can be ensured that swing cover 518 can always fit as close as possible to the patient's heat therapy side during the swing.

[0055] Please see Figure 10-12 In this embodiment of the invention, the hot pressing assembly 52 includes a second servo motor 521 fixedly connected to the top outer wall of the swing cover 518, a heat mesh cylinder 522 fixedly connected to the output shaft of the second servo motor 521, a central column 523 welded to the top inner wall of the heat mesh cylinder 522, plugs 524 welded to the periphery of the outer wall of the central column 523 at equal intervals, vent holes 525 opened at equal intervals on the periphery of the outer wall of the heat mesh cylinder 522, and ball plugs 526 slidably connected to the inner wall of the vent holes 525. The number of ball plugs 526 is the same as the number of plugs 524. A hot air chamber 527 is disposed between the heat mesh cylinder 522 and the central column 523 for circulating hot air.

[0056] As the servo motor 521 drives the heating mesh cylinder 522 to rotate, it will also drive the ball plugs 526 of each layer to rotate. As the swing cover 518 swings back and forth, the ball plugs 526 will come into contact with the patient's body in turn. On the one hand, the ball plugs 526 can achieve the function of massage by rolling on the patient's body. On the other hand, at this time, the ball plugs 526 are squeezed by force, and a gap will be generated between the ball plugs 526 and the vent 525. Hot air can pass through the gap and blow towards the patient for heat therapy.

[0057] Please see Figure 9 In this embodiment of the invention, the second gas delivery assembly 53 includes a second gas delivery pipe 531 rotatably connected to the center of the bottom outer wall of the heat exchange cylinder 522, and a second solenoid valve 532 installed on the outer wall of the second gas delivery pipe 531, wherein one end of the second gas delivery pipe 531 is fixedly connected to the first gas delivery pipe 431.

[0058] After opening the second air supply tube 531, the nebulizer will deliver the heated fumigation medicine through the first air supply tube 431 to the second air supply tube 531, and then deliver it to the hot air chamber 527 inside the hot mesh cylinder 522. Finally, it will be discharged through the gap between the ball plug 526 and the vent 525 and blown towards the patient for heat therapy.

[0059] Please see Figure 13 In this embodiment of the invention, a patient access component 6 is provided at the bottom of the central door 1. The patient access component 6 includes a base frame 61 provided on both sides of the central door 1, a guide rod 62 fixedly connected to the inner walls on both sides of the base frame 61, and a bed 63 slidably connected to the outer wall of the guide rod 62.

[0060] The outer walls on both sides of the central door 1 are respectively welded with a front cover 7 and a rear cover 8, and the guide rod 62 passes through the interior of the front cover 7, the central door 1 and the rear cover 8.

[0061] Before the hyperthermia treatment, the patient needs to lie on the bed 63. Then, the medical staff will push the bed 63 into the front cover 7 and the rear cover 8. After the positions of the first hyperthermia unit 4 and the second hyperthermia unit 5 are adjusted, the hyperthermia treatment can be performed on the patient's tumor.

[0062] The working principle of this invention is:

[0063] The patient first needs to lie on the bed 63, and then the medical staff will push the bed 63 into the front cover 7 and the rear cover 8. Then, the drive motor 21 drives the drive gear 22 to rotate, which controls the driven gear ring 23 to rotate, thereby adjusting the position of the pusher 3.

[0064] When the pusher 3 is on the same straight line as the patient's lesion, it pushes the first thermotherapy unit 4 or the second thermotherapy unit 5 closer to the patient through the inside of the servo guide rail 32.

[0065] When the first hyperthermia unit 4 approaches the patient, under the heating effect of the gas supply pipe 431, the hyperthermia cylinder 413 is pushed by the propulsion cylinder 412 to sequentially drive the first-level hyperthermia ring 414 to approach the second-level hyperthermia ring 415 and then to approach the third-level hyperthermia ring 416. During this process, the telescopic ball column 426 will move continuously until it is embedded in the air inlet 423, completing the connection and unblocking of the heat and gas of the first-level hyperthermia ring 414, the second-level hyperthermia ring 415 and the third-level hyperthermia ring 416. The heat gas containing the medicine will be sprayed out from the heat nozzle 417. It is possible to select a suitable size of hyperthermia ring to combine together for hyperthermia, which is suitable for some patients with concentrated tumor distribution.

[0066] Based on this, the rotating cylinder 34 can be used to drive the switching head 35 to rotate 180°, rotating the second hyperthermia mechanism 5 to the side closer to the patient. Under the heating effect of the second gas supply pipe 531, when the servo motor 512 drives the connecting rod 513, the second connecting rod 514 and the swing frame 515 to move, the swing cover 518 swings back and forth. At the same time, as the swing cover 518 swings back and forth, the servo motor 521 drives the heat mesh cylinder 522 to rotate, and the ball plug 526 will contact the patient's body in turn. On the one hand, the ball plug 526 can achieve the function of massage by rolling on the patient's body. On the other hand, at this time, the ball plug 526 is squeezed by force, and a gap will be generated between the ball plug 526 and the vent 525. Hot air can pass through the gap and blow to the patient for hyperthermia. This is suitable for hyperthermia of some patients with long tumor cross sections.

[0067] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
