Description

Technical Field

[0001] This utility model relates to the field of medical instrument technology, and in particular to a segmented combined ring resonant cavity. Background Technology

[0002] The basic principle of ultra-shortwave therapy equipment is that the power supply powers the energy generator, which in turn drives the energy generator to produce an energy source. The energy source is then transmitted to the ring resonant cavity through a signal line. The ring resonant cavity then applies the energy to the human body through coupling, causing the lesion site to generate endogenous heat, thereby treating the lesion.

[0003] However, existing ring resonant cavities are all integrated cavity structures (such as patent numbers CN201910762115.7 and CN201910762164.0, etc.), which makes it impossible to select the area that needs treatment. For example, if a patient only needs to be treated for frozen shoulder, their healthy parts such as the feet and legs will also be treated. This will not only damage the healthy parts, but also cause energy loss. Utility Model Content

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] refer to Figure 1 and Figure 2 A segmented combined ring resonant cavity includes a resonant unit 100, which includes an outer cylinder 1, a middle cylinder 2 and an inner cylinder 3 that are sequentially nested together; that is, the middle cylinder 2 is provided inside the outer cylinder, and the inner cylinder 3 is provided inside the middle cylinder 2, thereby forming a resonant cavity; the resonant unit 100 is connected to an energy generator 300 (magnetron, solid-state source, etc.) to generate an electric field.

[0030] Multiple resonant units 100 are provided and arranged along the axial direction; adjacent resonant units 100 are fixed and isolated by mounting plates 8.

[0031] Each resonant unit 100 can work independently or generate an electric field independently. That is, each resonant unit 100 can be controlled and operated independently to generate an electric field. For example, one resonant unit 100 can be made to work independently, all resonant units 100 can be made to work simultaneously, or some resonant units 100 can be made to work. This can be appropriately set according to the treatment situation.

[0032] Therefore, by setting up multiple resonant units 100 according to different treatment areas of the human body, more effective treatment can be carried out on the treatment areas, reducing energy loss and minimizing damage to non-treatment areas.

[0033] The length of each resonant unit 100 may be equally or unequally divided. For example, the length of each resonant unit 100 may be the same; or they may all be different; or some may be the same and others different; the appropriate settings can be made according to the structure of the human body, the treatment site, the treatment situation, etc.

[0034] The resonant unit 100 can be provided in two, three, four, or more. For example, when two resonant units 100 are provided, one corresponds to the lower half of the human body, and the other corresponds to the upper half of the human body;

[0035] When three resonant units 100 are provided, the first corresponds to the feet of the human body, the second corresponds to the legs of the human body, and the third corresponds to the chest and shoulders (torso) of the human body.

[0036] When four resonant units 100 are provided, the first corresponds to the feet of the human body, the second corresponds to the calves of the human body, the third corresponds to the thighs or buttocks of the human body, and the fourth corresponds to the chest and shoulders (torso) of the human body.

[0037] Of course, the human body can be divided into more detailed sections and more resonant units 100 can be set up, or it can be divided in other ways.

[0038] refer to Figure 1 The lengths of the outer cylinder 1, the middle cylinder 2, and the inner cylinder 3 decrease sequentially; the diameters of the outer cylinder 1, the middle cylinder 2, and the inner cylinder 3 also decrease sequentially. For example, the length and diameter of the outer cylinder 1 are L1 and D1, the length and diameter of the middle cylinder 2 are L2 and D2, and the length and diameter of the inner cylinder 3 are L3 and D3, then D1 > D2 > D3 and L1 > L2 > L3.

[0039] The outer cylinder 1 and the middle cylinder 2 are fixed together by a first spacer 61. The first spacer 61 is set between the outer cylinder 1 and the middle cylinder 2. Both ends of the first spacer 61 are provided with through holes. The first self-tapping screw 62 is passed through the corresponding outer cylinder 1 or middle cylinder 2 and screwed to the first spacer 61 to achieve fixation.

[0040] The middle cylinder 2 and the inner cylinder 3 are fixed together by a second spacer 71. The second spacer 71 is set between the middle cylinder 2 and the inner cylinder 3. Both ends of the second spacer 71 are provided with through holes. The second self-tapping screw 72 is passed through the corresponding outer cylinder 1 or middle cylinder 2 and screwed to the first spacer 61 to achieve fixation.

[0041] There is a certain distance between the middle cylinder 2 and the inner cylinder 3, thus forming the two poles of the open capacitor;

[0042] Both the first spacer 61 and the second spacer 71 are made of insulating materials, such as nylon and polytetrafluoroethylene, to achieve an insulating connection and fixation.

[0043] refer to Figure 1 The outer cylinder 1, the middle cylinder 2 and the inner cylinder 3 can all be made of thin metal sheets such as galvanized sheet, for example, galvanized sheet with a thickness of about 1mm; the first sealing plate 4 and the second sealing plate 5 are both made of metal; one end of the outer cylinder 1 is connected to the middle cylinder 2 through the first sealing plate 4, wherein the first sealing plate 4 is connected between the outer cylinder 1 and the middle cylinder 2 by welding, so as to form a conductive connection between the outer cylinder 1 and the middle cylinder 2;

[0044] The other end of the outer cylinder 1 is connected to the inner cylinder 3 through the second sealing plate 5. The second sealing plate 5 is connected between the outer cylinder 1 and the inner cylinder 3 by welding, so as to form a conductive connection between the outer cylinder 1 and the inner cylinder 3.

[0045] The working principle of the resonant unit 100: The energy generator 300 is connected to the resonant unit 100 through a coaxial cable and other signal lines; the outer conductor of the coaxial cable is energized to the outer cylinder 1, and the inner conductor of the coaxial cable is energized to the middle cylinder 2, so that the charge is stored in the annular resonant cavity capacitor electrode. Due to the potential difference between the inner cylinder 3 and the middle cylinder 2, the charge moves in the capacitor electrode of the resonant cavity to form an electric field. When radio frequency energy is sent through the coaxial cable and passes through the annular resonant cavity capacitor electrode, it works with the outer cylinder 1, the middle cylinder 2 and the inner cylinder 3 to form an annular resonant cavity for energy radiation output.

[0046] refer to Figures 2 to 4 The mounting plate 8 includes a first plate 81 and a second plate 82; the second plate 82 is vertically connected to the middle of the first plate 81, and the mounting plate 8 is roughly T-shaped.

[0047] The first plate 81 is connected to two adjacent outer cylinders 1 at both ends, and the second plate 82 is located between the two adjacent outer cylinders 1. Both the first plate 81 and the second plate 82 are provided with mounting holes 810; a third self-tapping screw 9 passes through the mounting hole 810 and is screwed to the outer cylinder 1. The outer cylinder 1 is provided with a through hole that mates with the third self-tapping screw 9, that is, the two adjacent resonant units 100 are fixed by means of the third self-tapping screw 9.

[0048] Mounting plate 8 is made of insulating materials, such as nylon, polytetrafluoroethylene, etc., to achieve an insulating gap.

[0049] To improve the stability of the connection, multiple mounting plates 8 can be set between two adjacent resonant units 100, such as three, four, five, six, etc.

[0050] Optionally, each resonant unit 100 can be connected to one energy generator 300, that is, the number of resonant units 100 and energy generators 300 are in one-to-one correspondence.

[0051] Optional, see reference Figure 5 The energy generator 300 forms multiple outputs through the power divider 400, and then connects to the corresponding resonant unit 100 through the circuit breaker, thereby realizing individual control and operation. The power divider 400 is existing technology and is used here.

[0052] This segmented combined ring resonator can be applied to medical equipment such as ultra-shortwave moxibustion cavity therapy devices.

[0053] The above description only discloses some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
