Description

Technical Field

[0001] This invention relates to the field of microwave therapy technology, specifically a multi-power microwave therapy device. Background Technology

[0002] Microwave therapy devices are effective for various inflammations, such as pelvic inflammatory disease, adnexitis, prostatitis, and arthritis. The thermal and non-thermal effects of microwave therapy devices can dilate local blood vessels, accelerate blood flow, promote the absorption and dissipation of inflammatory exudates, and enhance the phagocytic function of white blood cells, inhibiting bacterial growth and achieving an anti-inflammatory effect. Therefore, microwave therapy devices have a promising future.

[0003] For example, patent application CN118949282A discloses a dual microwave therapy device for pediatric pneumonia, including a therapy device, a support, a cushion, a wire winder, and a fixing component. The therapy device includes a main unit and a microwave therapy head. The top of the main unit has a collection cavity. The support includes a rotating shaft, a connecting sleeve, a pair of connecting rods, an adjusting seat, a threaded rod, a threaded sleeve, a sliding sleeve, and a connecting seat. The rotating shaft is rotatably installed inside one side of the collection cavity. The connecting sleeve is installed on the outside of the rotating shaft and connected to the pair of connecting rods. The adjusting seat is rotatably installed between the tops of the pair of connecting rods. The threaded rod is installed on one side of the adjusting seat and is threadedly engaged with the threaded sleeve. The sliding sleeve is rotatably connected to the threaded sleeve and slides on the outside of the threaded sleeve. The connecting seat is rotatably installed on the outside of the sliding sleeve and connected to the microwave therapy head. The wire winder is located on the outside of the main unit and winds up the wire. The two ends of the wire are electrically connected to the main unit and the microwave therapy head, respectively. The above structure completes the wire storage.

[0004] However, the aforementioned patent application still has some problems. When heating local tissues of the human body using the aforementioned microwave therapy device, the position of the radiation head is relatively fixed, and different parts of the human body tissue can withstand different temperatures, which can lead to excessively high local tissue temperatures, resulting in burns to the local tissues. At the same time, the relatively fixed position of the existing radiation head can lead to excessively high local tissue temperatures and limited treatment area.

Detailed Implementation

[0065] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0066] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0067] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0068] This invention discloses a multi-power microwave therapy device, with reference to... Figures 1-16 ,include:

[0069] A workbench 1, an adjustment bracket 2 mounted on the workbench 1, and a housing 3 mounted on the adjustment bracket 2; a heating unit 4, disposed within the housing 3, for increasing the temperature of local tissue; the heating unit 4 includes a first adjustment component 41, a second adjustment component 42, and a radiation head; the radiation head includes a first radiation head 417 mounted on the first adjustment component 41 and a second radiation head 426 connected to the second adjustment component 42; the first adjustment component 41, disposed within the housing 3, is used to drive the first radiation head 417 and the second radiation head 426 to rotate, ensuring that the rotational speed of the first radiation head 417 is different from that of the second radiation head 426; the second adjustment component 42, connected to the first adjustment component 41, allows the second radiation head 426 to revolve around the axis of the second adjustment component 42 while also adjusting the distance between the second radiation head 426 and the local tissue; the first adjustment component 41, in turn, drives the first radiation head 417 and the second radiation head 426 to rotate, and the first radiation head 417... The rotation speed of the first radiation head 417 is different from that of the second radiation head 426. The area irradiated by the first radiation head 417 is the transition zone, while the area heated by the second radiation head 426 is the treatment zone. By increasing the rotation speed of the first radiation head 417 and shortening the interval between the second radiation heads 426, the heating uniformity of the radiation heads can be improved, thereby enhancing the treatment effect. The second adjustment component 42 can change the distance and angle between the second radiation head 426 and the local tissue of the human body, ensuring the uniformity of heating by the second radiation head 426 and avoiding excessively high local temperatures. The third adjustment component 43 allows the radiation heads to move in a wave-like manner, preventing excessively high local temperatures from damaging the human tissue. Through the cooperation of the first adjustment component 41, the second adjustment component 42, and the third adjustment component 43, the working areas of the first radiation head 417 and the second radiation head 426 can be adjusted to complete the heating of the human tissue while avoiding excessively high local temperatures that could damage the human tissue.

[0070] The first adjustment assembly 41 includes a snap-fit ​​seat 411 detachably connected to the housing 3, a drive motor 412 disposed on the snap-fit ​​seat 411, a rotary seat 413 connected to the output end of the drive motor 412, a drive groove 418 formed in the inner wall of the rotary seat 413, a transmission member 415 located in the drive groove 418, a rotating core 414 connected to the transmission member 415, and a snap-fit ​​plate 416 connected to the rotating core 414; wherein the transmission member 415 is provided with a snap-fit ​​block, and the transmission member 415 is connected to the housing 3 through the snap-fit ​​block; the transmission member 415 is connected to the snap-fit ​​plate 416; the transmission member 415... 15 includes a limiting frame 4110, which has a sliding groove, a slider 4111 slidably connected to the sliding groove, and a guide rod 4112 passing through the slider 4111; one end of the guide rod 4112 is located in the drive groove 418, and the other end of the guide rod 4112 is located in the V-shaped driven groove 419; the limiting frame 4110 is connected to a snap-fit ​​block, which sets the limiting frame 4110 on the housing 3; through the cooperation of the guide rod 4112 and the tortuous inclined surface, both the rotating core 414 and the rotating seat 413 rotate at different speeds; when the first radiating head 417 and the second radiating head 413 are needed... When 26 rotates, the drive motor 412 starts working. The moving drive motor 412 drives the rotating seat 413 to rotate, and the moving rotating seat 413 drives the drive groove 418 to move, thereby causing the guide rod 4112 to move within the drive groove 418. The moving guide rod 4112 then drives the slider 4111 to move along the length of the limit frame 4110, causing the other end of the guide rod 4112 to move within the V-shaped driven groove 419, thereby driving the rotating core 414 to rotate. The moving rotating core 414 then drives the retaining plate 416 to rotate, thereby driving the radial head on the second adjustment assembly 42. Preliminary position adjustments are made, and the rotation speed of the rotating base 413 differs from that of the receiving plate 416. This allows the first radiation head 417 and the second radiation head 426 to distribute microwave energy more evenly within the tissue at different rotation speeds. The second radiation head 426 concentrates energy, while the first radiation head 417 continuously adjusts the energy application point through rapid rotation, avoiding excessive or insufficient local energy concentration. This reduces treatment blind spots or local overheating caused by uneven energy distribution, improving the precision and effectiveness of treatment. Furthermore, the proximity of the second radiation heads 426 to each other, with relatively concentrated energy, allows microwaves to penetrate deeper into the tissue, achieving effective treatment of deep lesions. The first radiation head 417, mounted on top, can rapidly scan and radiate the relatively superficial tissue, expanding the lateral coverage of the treatment and addressing treatment needs at different depths and widths.

[0071] The drive groove 418 includes two identical limiting grooves connected end-to-end, and the limiting grooves are spiral-shaped. The rotating core 414 has a zigzag guide groove on its circumference, and the guide groove includes multiple V-shaped driven grooves 419. The outer bottom of the V-shaped driven groove 419 has a first rounded corner, and the connection between two adjacent V-shaped driven grooves 419 and near the locking plate 416 has a second rounded corner. The transmission member 415 can move in the limiting groove. There is a predetermined angle between the line connecting the outer bottom and the inner bottom of the V-shaped driven groove 419 and the axis of the rotating core 414. Guide protrusions are provided at the connection between two adjacent V-shaped driven grooves 419 and away from the locking plate 416, and at the inner bottom of the V-shaped driven groove 419. The inner wall of the V-shaped driven groove 419 is provided with... The device has a twisted inclined surface, and the degree of twist gradually decreases towards the first or second fillet. A guide groove allows the guide rod 4112 to move within it, thereby driving the rotating core 414 to rotate. The first and second fillets in the V-shaped driven groove 419 prevent collisions between the V-shaped driven groove 419 and the guide rod 4112, thus avoiding damage to the guide rod 4112. Furthermore, by maintaining a predetermined angle between the line connecting the outer bottom and inner bottom of the V-shaped driven groove 419 and the axis of the rotating core 414, and in conjunction with the inertia generated during the rotation of the rotating core 414, the guide rod 4112 can move from one V-shaped driven groove 419 to another, ensuring the smooth operation of the rotating core 414.

[0072] The second adjustment assembly 42 includes a placement base 421 detachably connected to the retaining plate 416, an adjustment motor 422 fixedly connected to the placement base 421, a rotating shaft 423 disposed at the output end of the adjustment motor 422, a rotating frame 424 and a drive gear 427 sleeved on the rotating shaft 423, and a limiting part 425 disposed on the rotating frame 424 and connected to the drive gear 427; the second radiating head 426 is connected to one end of the limiting part 425; the limiting part 425 includes a limiting seat 4251 disposed on the placement base 421, a set of bushings 4252 disposed on the rotating frame 424, a drive shaft 4253 for connecting the two bushings 4252, and a fitting sleeved on the placement base 421. The drive shaft 4253 has a driven gear 4254 meshing with the drive gear 427, a drive seat 4255 sleeved on the drive shaft 4253, and a drive wheel 4256 disposed on the drive seat 4255; the limiting seat 4251 includes two opposing capping cams with identical structures; a channel for the drive wheel 4256 to move is formed between the two capping cams; the driven gear 4254 and the drive wheel 4256 move by rotating the rotating frame 424, thereby completing the synchronous adjustment of the height and angle of the second radiating head 426; a ball bearing is provided between the drive gear 427 and the rotating shaft 423, and the drive gear 427 is connected to the placement seat 421;

[0073] When it is necessary to simultaneously adjust the height and angle of the second radiation head 426, the adjustment motor 422 starts working. The moving adjustment motor 422 drives the rotating frame 424 to move, thereby moving the limiting part 425. Since the drive gear 427 is connected to the driven gear 4254, it can drive the drive shaft 4253 to rotate, thereby adjusting the radiation area of ​​the second radiation head 426. Due to the movement of the rotating frame 424, the drive wheel 4256 can move in the channel on the limiting seat 4251, thereby adjusting the height of the second radiation head 426, thus completing the adjustment of the height and angle of the radiation head, ensuring the uniformity of local treatment, and avoiding damage caused by excessive local temperature.

[0074] The capping cam is provided with a first arc-shaped channel 42511, a second arc-shaped channel 42512 connected to the first arc-shaped channel 42511, a third arc-shaped channel 42513 connected to the second arc-shaped channel 42512, and a fourth arc-shaped channel 42514 connected to the third arc-shaped channel 42513; the other end of the fourth arc-shaped channel 42514 is connected to the first arc-shaped channel 42511; the second arc-shaped channel 42512 and the fourth arc-shaped channel 42514 have different inclination angles; the rotating frame 424 is also provided with a limiting rod 4257, the limiting rod 4257 has a connecting groove in the axial direction, and the drive seat 4255 has a limiting protrusion; the limiting protrusion is located in the connecting groove; through the provided arc-shaped channels, the distance between the second radiation head 426 and the local tissue can be made different, and through the provided adjusting motor 422, the position of the second radiation head 426 can be rotated a second time, thereby adjusting the radiation area of ​​the second radiation head 426 and increasing its treatment position.

[0075] Example 2

[0076] The first adjustment component 41 can be replaced by the third adjustment component 43;

[0077] The third adjustment component 43 includes a mounting frame 431 connected to the housing 3, a support frame 436 and a rotary motor 432 disposed on the mounting frame 431, a rotating shaft 433 connected to the output end of the rotary motor 432, a plurality of transmission parts evenly sleeved on the rotating shaft 433, an abutting wheel 435 abutting against the outer wall of the transmission part, a connecting rod 438 connected to the abutting wheel 435, and a connecting seat 437 mounted on the connecting rod 438; the radiating head is located on the connecting seat 437; the support frame 436 is provided with a limiting hole. The connecting rod 438 passes through the limiting hole; the transmission part includes a plurality of drive rings 434; wherein the drive ring 434 includes a plurality of first drive rings and a plurality of second drive rings; the plurality of first drive rings and the plurality of second drive rings are arranged in a comb-like shape and spaced apart; in the image corresponding to the right view of the third adjustment component 43, there is an overlapping area between the first drive rings and the second drive rings, the rotating shaft 433 is located in the overlapping area and connected to the drive rings 434, wherein the axes of the abutment wheels 435 that contact the first drive rings and the second drive rings respectively coincide;

[0078] After replacing the first adjustment component 41 with the third adjustment component 43, the rotary motor 432 starts working during local treatment. The rotating motor 432 drives the rotating shaft 433 to rotate, thereby causing the drive ring 434 to rotate. The moving drive ring 434 drives the abutment wheel 435 to move, thereby adjusting the position of the second adjustment component 42 on the connecting seat 437 and changing the position of the second radiation head 426. This allows the second radiation head 426 to heat the local tissue in a wave-like motion, improving the uniformity of local heating and preventing excessive temperature.

[0079] Because the first radiating head 417 and the second radiating head 426 are positioned differently along the axis of the rotating core 414, the second radiating head 426 is closer to the local tissue than the first radiating head 417. Therefore, after the radiating head is energized, the heating effect of the first radiating head 417 on the local tissue is less than that of the second radiating head 426. Since the annular structure formed by multiple first radiating heads 417 is nested on the second radiating head 426, a transition zone is formed between the predetermined heating area and the non-heating area. The heating temperature of the transition zone is lower than that of the heating area. Therefore, the transition zone formed by heating the local tissue with the first radiating head 417 allows blood circulation to remain relatively stable and orderly as it changes from high temperature to low temperature, avoiding excessive concentration or poor flow of blood in the local area. This is beneficial for the body to evenly distribute and absorb heat, and also helps the body's self-regulation mechanism to function better, maintaining the stability of the internal environment.

[0080] Working principle description: When microwave therapy is required on a specific part of the patient, the worktable 1 equipped with the microwave therapy device can be pushed to the predetermined position. Then, the medical staff can start the adjustment bracket 2 to make the radiation head position. After the radiation head is powered on, it can generate heat to heat the local tissue and complete the microwave therapy.

[0081] After the position adjustment of the worktable 1 is completed, the first radiation head 417 and the second radiation head 426 begin to work, thereby completing the heating of the patient's local tissues. When the first radiation head 417 and the second radiation head 426 need to rotate, the drive motor 412 starts to work. The moving drive motor 412 can drive the rotating seat 413 to rotate, and the moving rotating seat 413 can drive the drive groove 418 to move, thereby causing the guide rod 4112 to move within the drive groove 418. The slider 4111 can move along the length of the limit frame 4110, thereby causing the other end of the guide rod 4112 to move within the V-shaped driven groove 419, which in turn drives the rotating core 414 to rotate. The moving rotating core 414 can drive the retaining plate 416 to rotate, thereby driving the radiating head on the second adjusting assembly 42 to perform initial position adjustment. When it is necessary to simultaneously adjust the height and angle of the second radiating head 426, the adjusting motor 422 starts working, and the moving adjusting motor 422 drives the rotating core 414 to rotate. The rotating frame 424 moves, which in turn drives the limiting part 425 to move. Since the drive gear 427 is connected to the driven gear 4254, it can drive the drive shaft 4253 to rotate, thereby adjusting the radiation area of ​​the second radiation head 426. Due to the movement of the rotating frame 424, the drive wheel 4256 can move in the channel on the limiting seat 4251, thereby adjusting the height of the second radiation head 426, thus completing the adjustment of the height and angle of the radiation head. After replacing the first adjustment component 41 with the third adjustment component 43, when performing local treatment, the rotary motor 432 starts to work. The rotating motor 432 drives the rotating shaft 433 to rotate, thereby rotating the drive ring 434. The moving drive ring 434 drives the abutment wheel 435 to move, thereby adjusting the position of the second adjustment component 42 on the connecting seat 437, changing the position of the second radiation head 426, so that the second radiation head 426 heats the local tissue in a wave-like motion, improving the uniformity of local heating and avoiding excessive temperature.
