The electrolyte ions and dipoles in the human body will move, so the human body generates heat and achieves a heating effect. The radio frequency thermotherapy device is used to heat the parts of the human body containing cancer cells. The high heat destroys the cell membrane structure of the cancer cells and the DNA and RNA in the cell nucleus, causing protein denaturation and necrosis, which can achieve the effect of treating cancer. The radio frequency thermotherapy device is equipped with a temperature measuring device to measure the temperature of the heated part of the human body.

[0004] The temperature measuring device includes an optical fiber temperature sensor, which determines the temperature of the heated part of the human body through the single influence relationship between fluorescence lifetime and temperature. During use, the existing device directly pulls the probe of the optical fiber sensor and places it on the heated part of the human body. Since the optical fiber in the optical fiber temperature sensor is relatively fragile, it is easily damaged by external forces such as bending, stretching, and compression. Therefore, there is a problem that the optical fiber temperature sensor is damaged, affecting the adjustment of the working frequency of the radio frequency thermal therapy device.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 8 As shown, a temperature measuring device of a radio frequency thermal therapy instrument described in an embodiment of the present invention includes a host 1 and a probe 2, wherein the host 1 is installed on the radio frequency thermal therapy instrument, and the probe 2 is used to measure the temperature of a healing part of a human body. It also includes a fixing component 3 and a winding component 4 installed on one end of the probe 2 for detection, wherein the fixing component 3 includes a frame plate 31 installed on the probe 2, and the winding component 4 includes a plurality of pull ropes 41 installed between the host 1 and the frame plate 31, and the length of the pull rope 41 is less than the length of the probe 2.

[0023] Specifically, the temperature measuring device includes an optical fiber temperature sensor, which is composed of a host 1 and a probe 2. The probe 2 includes a cable connected thereto. During treatment, the human body is heated by the radio frequency probe of the radio frequency thermotherapy device. The probe 2 of the temperature measuring device measures the temperature of the heated part in real time and feeds the data back to the host 1. The host 1 adjusts the frequency of the radio frequency probe to maintain the temperature of the heated part within the treatment temperature range. During use, the existing device directly pulls the probe 2 and places it on the heated part of the human body. Since the probe 2 contains optical fiber, the optical fiber itself is relatively fragile and can be easily damaged by external forces such as bending, stretching, and compression. Therefore, there is a problem that the optical fiber temperature sensor is damaged, which affects the adjustment of the working frequency of the radio frequency thermotherapy device. Before work, the probe 2 is connected to the host 1, and the patient lies on the radio frequency thermotherapy device so that the probe 2 contains The area with cancer cells, i.e., the area to be heated, is located under the RF generator of the RF thermal therapy device. The frame 31 is pulled to drive the probe 2 and the pull rope 41 to move together, so that the probe 2 is located at the patient's position to be heated. The probe 2 is fixed to the skin surface by medical tape, and then the RF thermal therapy device is controlled to work to heat the area to be heated. The probe 2 measures the temperature of the area to be heated, and the frequency of the RF thermal therapy device is adjusted to maintain the temperature within the treatment temperature range. The pull rope 41 and the frame 31 are set, and the probe 2 is pulled by the frame 31. Since the length of the pull rope 41 is less than the length of the probe 2, during the pulling process, if the pulling length is too long, the pull rope 41 is first tightened to indicate that it cannot be stretched any further. The probe 2 is always in a relaxed state, avoiding the problem of damage to the fibers in the probe 2 due to stretching.

[0024] like Figure 1-Figure 3 As shown, the winding assembly 4 also includes: a plurality of storage plates 42 for winding the pull rope 41 and the probe 2 respectively; a storage shell 43 installed outside the storage plate 42, the storage plate 42 is threadedly connected to the storage shell 43, and the storage shell 43 is slidably connected to the host 1.

[0025] Specifically, in the initial state, the pull rope 41 and the probe 2 are both wound on the storage plate 42. When the probe 2 needs to be moved, the frame plate 31 is pulled, and the frame plate 31 pulls the pull rope 41, so the storage plate 42 rotates, so that the probe 2 and the pull rope 41 are stretched to allow the frame plate 31 to move, and the probe 2 and the pull rope 41 are synchronously stretched at the position between the storage plate 42 and the host 1, so the storage plate 42 and the storage shell 43 move downward relative to the host 1. After use, the storage plate 42 is rotated to wind up the pull rope 41 and the probe 2, so that the probe 2 is stored, which is more beautiful and avoids the occurrence of situations such as being accidentally pressed.

[0026] like Figure 3 As shown, the storage plate 42 wound around the probe 2 adopts a telescopic structure, and a sensor 45 is installed on the storage plate 42.

[0027] Specifically, when in use, the winding plate for storing the pull rope 41 is controlled to rotate, driving the storage plate 42 of the winding probe 2 to rotate synchronously. When the probe 2 is stuck, the storage plate 42 of the winding pull rope 41 continues to rotate, and the storage plate 42 of the winding probe 2 rotates synchronously, but the storage plate 42 of the winding probe 2 shrinks, causing the sensor 45 to be triggered, so as to promptly notify the operator for processing.

[0028] like Figure 2 and Figure 4 As shown, the fixing assembly 3 includes a suction cup structure 32 installed on the frame 31, and the suction cup structure 32 is used to fix the frame 31 and the probe 2 to the healing part of the human body.

[0029] Specifically, the probe 2 is fixed to the patient's heating position through the suction cup structure 32. The part of the suction cup structure 32 that contacts the human body can be made of glass or rubber material, which can be suitable for patients who are allergic to medical tapes and has a wider range of applicable populations.

[0030] like Figure 2 As shown, the fixing assembly 3 includes a plurality of groups of suction cup structures 32 , and the plurality of suction cup structures 32 are distributed in a circular array on the frame plate 31 .

[0031] Specifically, since the suction cup is fixed to the skin by negative pressure, the skin maintains negative pressure for a long time, and the skin capillaries may rupture and red spots may occur, which affects the appearance. In addition, the suction cup is under negative pressure and is not circulated with the outside air. After the patient's part containing cancer cells is heated, the skin will sweat, and the sweat and hot air in the suction cup are not circulated with the outside world. The temperature in the suction cup is higher than the temperature on the skin in contact with the air, which may cause skin burns. By setting up multiple suction cup structures 32, after one of the suction cup structures 32 is fixed on the skin for a period of time, another suction cup structure 32 is controlled to be fixed on the skin, and then the initial suction cup structure 32 is controlled to release the skin, and several suction cup structures 32 are circulated in sequence, and multiple suction cup structures 32 work in turn to avoid a situation where a piece of skin is under negative pressure for a long time. After adsorption for a period of time, the suction cup structure 32 can circulate with the outside air to avoid the situation where the sweat in the suction cup structure 32 cannot be discharged, thereby improving the above-mentioned problems.

[0032] like Figure 4-Figure 7 As shown, the suction cup structure 32 includes: a No. 1 tube 321 detachably mounted on the frame plate 31; a No. 2 tube 322 slidably mounted on the No. 1 tube 321; a No. 1 ring 323 rotatably mounted on the No. 1 tube 321, a No. 1 slide groove 324 is provided on the No. 1 ring 323, the No. 2 tube 322 is slidably connected with the No. 1 ring 323 through the No. 1 slide groove 324, the No. 1 ring 323 and the No. 1 slide groove 324 rotate one circle to make the No. 2 tube 322 reciprocate up and down; a No. 2 spring 325 installed between the No. 2 tube 322 and the No. 1 tube 321, the No. 2 tube 322 When moving downward relative to the No. 1 tube 321, the No. 2 spring 325 is compressed; a cover plate 326 is slidably installed on the No. 1 tube 321 up and down, and the cover plate 326 is used to block the air outlet above the No. 1 ring 323. A No. 2 slide groove 327 is opened on the cover plate 326; a connecting plate 328 is fixedly installed on the No. 1 ring 323, and the connecting plate 328 is slidably connected to the cover plate 326 through the No. 2 slide groove 327. The connecting plate 328 rotates one circle, so that the cover plate 326 moves back and forth up and down; a No. 3 spring 329 is installed between the cover plate 326 and the No. 1 tube 321.

[0033] Specifically, the first slide groove 324 is composed of three grooves a, b, and c, the second slide groove 327 is composed of four grooves d, e, f, and g, and the second tube 322 contains a protrusion that slides on the first slide groove 324. In the initial state, the second tube 322 is at the connection point of a and c, the connecting plate 328 is at the connection point of e and f, and the third spring 329 is in a stretched state; When fixing the probe 2, place the No. 1 tube 321 on the skin, press down the frame plate 31, so that the No. 1 tube 321 is in close contact with the skin, and then control the No. 1 ring 323 to rotate clockwise (in Figure 6 When the No. 1 slide 324 rotates, the No. 2 pipe 322 slides at a, causing the No. 2 pipe 322 to move downward. The No. 2 pipe 322 moves downward, causing the air in the No. 1 pipe 321 to be squeezed out by the No. 2 pipe 322. At this time, the No. 2 spring 325 is compressed, and the No. 1 ring 323 rotates accordingly, driving the connecting plate 328 to rotate. The connecting plate 328 slides in e first, and the cover plate 326 remains stationary. When the No. 2 pipe 322 is about to move to the connection point between a and b, the connecting plate 328 First, it slides to the intersection of e and d. Under the action of the elastic force of the third spring 329, the cover plate 326 moves downward to block the outlet position of the second tube 322. At this time, the connecting plate 328 slides in d, the first ring 323 continues to rotate, the connecting plate 328 slides in g, the cover plate 326 remains stationary, and the second tube 322 moves to the connection point of a and b. Under the action of the elastic force of the second spring 325, the second tube 322 slides upward in b. Due to the gap between the second tube 322 and the first tube 321, The air outlet is blocked, and the second tube 322 moves upward, so that the space in the first tube 321 increases, but the volume of the gas remains unchanged, so the first tube 321 and the second tube 322 become low-pressure states, so that the suction cup assembly is fixed on the skin. At this time, the connecting plate 328 is located in g, and the first ring 323 rotates half a circle. The first ring 323 continues to rotate, and the connecting plate 328 slides first in g and then slides to f, so that the cover plate 326 slides upward, so that the third spring 329 is compressed. The second tube 322 and the first tube 321 are connected to the air, and the suction cup assembly releases the skin until the connecting plate 328 moves to the connecting point of f and e. At the same time, the second tube 322 slides in c, and the second tube 322 remains stationary. When the connecting plate 328 is located at the connecting point of f and e, the second tube 322 is located at the connecting point of c and a. At this time, the first ring 323 rotates a full circle, and this cycle is repeated. By rotating the first ring 323, the suction cup structure 32 is adsorbed on the skin and the skin is released.

[0034] like Figure 2 and Figure 4 As shown, the fixing assembly 3 also includes: a number one gear 33 for driving the number one ring 323 to rotate, the number one gear 33 is fixedly connected to the number one ring 323; a number two gear 34 for driving the number one gear 33 to rotate, the number two gear 34 is rotatably connected to the frame plate 31, and the number two gear 34 is meshingly connected to the number one gear 33; a number three gear 35 rotatably mounted on the frame plate 31, the number three gear 35 is meshingly connected to the number two gear 34, and the number three gear 35 intermittently drives the number two gear 34 to rotate.

[0035] Specifically, when in use, the third gear 35 can be driven to rotate by a motor, manually, or by setting a spring between the third gear 35 and the frame plate 31. The third gear 35 can be an incomplete gear; the third gear 35 is controlled to rotate clockwise, driving the second gear 34 to rotate clockwise intermittently, and the second gear 34 rotates once, driving the first gear 33 to rotate half a circle clockwise, that is, completing an action of sucking or releasing the skin, by controlling the initial positions of the connecting plates 328 of each suction cup structure 32 and the second tube 322 on the second slide groove 327 and the first slide groove 324, so that the first ring When 323 rotates half a circle, the suction cup structure 32 that is not adsorbed on the skin is adsorbed on the skin first, and the connecting plate 328 of the suction cup structure 32 that has been adsorbed on the skin slides in g. During this period, the pressure between the No. 1 tube 321 and the No. 2 tube 322 is still in a low-pressure state. When the suction cup structure 32 that is not adsorbed on the skin is changed to the adsorption state, the connecting plate 328 of the suction cup structure 32 that has been adsorbed on the skin slides into f, so that the cover plate 326 moves upward, and the No. 1 tube 321 and the No. 2 tube 322 are connected to the outside world, and the skin can be released. This cycle can realize the uninterrupted conversion of the state of the suction cup structure 32.

[0036] like Figure 2 As shown, the fixing assembly 3 also includes: a connecting block 36 fixedly mounted on the probe 2, the connecting block 36 being slidably connected to the frame plate 31; a push plate 37 for pushing the connecting block 36 to move, a No. 1 pressing structure 38 being installed between the push plate 37 and the frame plate 31 for engaging by pressing once and separating by pressing again; and a No. 4 spring 39 installed between the frame plate 31 and the push plate 37.

[0037] Specifically, the No. 1 pressing structure 38 adopts a structure that is pressed once to combine and pressed again to separate, which is similar to a press-type trash can lid. When the suction cup structure 32 is placed on the skin, the push plate 37 is pressed down, and the push plate 37 moves downward, driving the connecting block 36 and the end of the probe 2 to move downward until the end of the probe 2 contacts the skin. At the same time, the push plate 37 moves downward, pressing the No. 1 pressing structure 38 once. After the probe 2 contacts the skin, the No. 1 pressing structure 38 is combined. At this time, the No. 4 spring 39 is in a compressed state. After the temperature measurement is completed, the No. 1 pressing structure 38 is pressed downward again to separate the No. 1 pressing structure 38. Under the action of the elastic force of the No. 4 spring 39, the push plate 37, the connecting block 36 and the end of the probe 2 move upward, so that the end of the probe 2 is retracted into the inside of the frame plate 31 to avoid the end of the probe 2 being accidentally touched when not in working state and causing damage.

[0038] like Figure 7 As shown, the fixing assembly 3 further includes: a third tube 310 fixed to the outer periphery of the first ring 323; A slide bar 311 is slidably mounted on the No. 1 tube 321; a round block 312 is rotatably mounted on the No. 3 tube 310, the round block 312 is threadedly connected to the slide bar 311, two groups of colors are arranged on the round block 312 in half, and the portion of the No. 3 tube 310 that contacts the round block 312 is made of transparent material, and half of the round block 312 can be observed through the No. 3 tube 310.

[0039] Specifically, in the initial state, only one color of the round block 312 can be observed from the No. 3 tube 310. During the upward movement of the No. 2 tube 322, a low pressure state is formed in the No. 1 tube 321, causing the slide bar 311 to slide into the No. 1 tube 321. Since the round block 312 is threadedly connected to the slide bar 311, the round block 312 rotates half a circle, so that another color of the round block 312 can be observed from the No. 3 tube 310. At this time, the No. 6 spring is stretched. When the No. 1 tube 321 and the No. 2 tube 322 are connected to the air, the slide bar 311 slides into the No. 3 tube 310 under the action of the elastic force of the No. 6 spring. At this time, the round block 312 rotates to the initial state. By setting the round block 312, the air pressure state in the No. 1 tube 321 and the No. 2 tube 322 can be observed according to the color of the round block 312 to determine whether the suction cup structure 32 is firmly attached to the skin.

[0040] like Figure 7 and Figure 8 As shown, the fixing assembly 3 also includes: a block 313 slidably mounted on the cover plate 326; a No. 5 spring 314 installed between the block 313 and the cover plate 326; and a No. 2 pressing structure 315 fixedly mounted between the block 313 and the cover plate 326, wherein the No. 2 pressing structure 315 is consistent with the No. 1 pressing structure 38.

[0041] Specifically, in the initial state, the No. 2 pressing structure 315 is in a combined state, the blocking block 313 blocks the middle position of the cover plate 326, and the No. 5 spring 314 is in the pull rope 41 state. After use, the No. 2 pressing structure 315 can be separated by pressing the blocking block 313. The blocking block 313 moves upward under the elastic force of the No. 5 spring 314, so that the No. 1 tube 321 and the No. 2 tube 322 can be connected to the outside through the middle position of the cover plate 326, so that the suction cup structure 32 releases the skin, which is easy to use.

[0042] Working principle: before working, connect the probe 2 and the host 1, and the patient lies on the radio frequency thermal therapy device first, so that the part containing cancer cells, that is, the part to be heated, is located under the radio frequency generator of the radio frequency thermal therapy device, and pull the frame 31 to drive the probe 2 and the pull rope 41 to move together, so that the probe 2 is located at the patient's position to be heated, and press the frame 31 downward to make the No. 1 tube 321 close to the skin, control the No. 3 gear 35 to rotate clockwise, and drive the No. 2 gear 34 to rotate clockwise intermittently. The No. 2 gear 34 rotates, so that the No. 1 gear 33 and the No. 1 ring 323 rotate clockwise (looking from top to bottom in the figure), and the No. 1 slide 324 rotates, so that the No. 2 tube 322 slides at a, so that the No. 2 tube 322 moves downward, and the No. 2 tube 322 moves downward. The air in the No. 1 tube 321 is squeezed out by the No. 2 tube 322. At this time, the No. 2 spring 325 is compressed. The No. 1 ring 323 rotates accordingly and drives the connecting plate 328 to rotate. The connecting plate 328 slides in e first, and the cover plate 326 remains stationary. When the No. 2 tube 322 is about to move to the connection point of a and b, the connecting plate 328 first slides to the intersection of e and d. Under the action of the elastic force of the No. 3 spring 329, the cover plate 326 moves downward to block the air outlet position of the No. 2 tube 322. At this time, the connecting plate 328 slides in d, the No. 1 ring 323 continues to rotate, the connecting plate 328 slides in g, the cover plate 326 remains stationary, and the No. 2 tube 322 moves to the connection point of a and b. The No. 2 tube 322 is under the elastic force of the No. 2 spring 325 Under the action, it slides upward in b. Since the air outlet position between the No. 2 tube 322 and the No. 1 tube 321 is blocked, the No. 2 tube 322 moves upward, which increases the space in the No. 1 tube 321, but the volume of the gas remains unchanged. Therefore, the No. 1 tube 321 and the No. 2 tube 322 become in a low pressure state, so that the suction cup assembly is fixed on the skin. At this time, the connecting plate 328 is located in g, and the No. 1 ring 323 rotates half a circle. The No. 1 ring 323 continues to rotate, and the connecting plate 328 slides in g first, and then slides to slide in f, so that the cover plate 326 slides upward, so that the No. 3 spring 329 is compressed. At the same time, the No. 2 tube 322 and the No. 1 tube 321 are connected to the air, and the suction cup assembly releases the skin until the connecting plate 328 moves to the connecting point of f and e. At the same time, the No. 2 tube 322 slides in c, and the No. 2 tube 322 remains stationary. When the connecting plate 328 is located at the connecting point of f and e, the No. 2 tube 322 is located at the connecting point of c and a. At this time, the No. 1 ring 323 rotates a full circle, and in this cycle, the suction cup structure 32 is adsorbed on the skin and released from the skin by rotating the No. 1 ring 323. The No. 2 gear 34 rotates once, driving the No. 1 gear 33 to rotate half a circle clockwise, that is, the action of adsorbing the skin or releasing the skin is completed once. By controlling the initial positions of the connecting plates 328 of each suction cup structure 32 and the No. 2 tube 322 on the No. 2 slide groove 327 and the No. 1 slide groove 324, when the No. 1 ring 323 rotates half a circle, the suction cup structure 32 that is not adsorbed on the skin is first adsorbed on the skin.The connecting plate 328 of the suction cup structure 32 that has been adsorbed on the skin slides in g, and during this period of time, the pressure between the first tube 321 and the second tube 322 is still in a low pressure state. When the suction cup structure 32 that has not been adsorbed on the skin changes to the adsorption state, the connecting plate 328 of the suction cup structure 32 that has been adsorbed on the skin slides into f, so that the cover plate 326 moves upward, and the first tube 321 and the second tube 322 are connected to the outside world, and the skin can be released. In this way, the state of the suction cup structure 32 is continuously changed. After use, the second pressing structure 315 can be separated by pressing the blocking block 313. The blocking block 313 moves upward under the elastic force of the fifth spring 314, so that the first tube 321 and the second tube 322 can be connected to the outside world through the middle position of the cover plate 326, so that the suction cup structure 32 in the adsorption state releases the skin, which is convenient to use.
