[0001] The present invention relates to the technical field of medical devices, and in particular to an external kit of an intelligent temperature-controlled brachytherapy applicator. Background Art
[0002] Applicators are a type of medical device used in brachytherapy. They play a vital role in radiotherapy and have a positive impact on tumor treatment, particularly in radical radiotherapy for cervical cancer. They can further improve local tumor control during interstitial irradiation. Applicators deliver radiotherapy using internal irradiation. The hollow applicator is placed within the patient's body near the tumor. Afterloading brachytherapy is used to guide the radiation source to the tumor site, where it releases radiation to kill cancer cells.
[0003] Hyperthermia is the use of physical energy to raise the temperature of tumor tissue to an effective treatment temperature for a period of time, and to take advantage of the difference in temperature tolerance between normal tissue and tumor cells to effectively kill malignant tumor cell tissues and synergistically enhance radiotherapy sensitization. Radiotherapy and hyperthermia have different sensitivities to cells in different phases of the cell division cycle, and the two have complementary effects. A large number of clinical studies have found that radiotherapy combined with hyperthermia can significantly improve the local area control rate of tumors, but there is a certain time difference when performing radiotherapy and hyperthermia in clinical practice, and hyperthermia and radiotherapy cannot be performed at the same time. In addition, the current external hyperthermia machine has problems such as inaccurate positioning and a large range. Therefore, the inventors designed a treatment plan that combines hyperthermia and radiotherapy, and proposed an intelligent temperature-controlled close-range radiotherapy applicator kit to address the above problems.

[0041] Example 1: Please refer to Figure 1 , the present invention provides a technical solution:
[0042] An intelligent temperature-controlled brachytherapy applicator outer set comprises an applicator 1 and an outer set 3;
[0043] An outer sleeve 3 for performing deep regional hyperthermia on a patient is installed on the outer side of the traveling end of the applicator 1. A heat-insulating sleeve 4 for heat insulation is installed on one side of the outer sleeve 3. A mounting groove 8 is provided in the center of the heat-insulating sleeve 4.
[0044] The installation slot 8 is internally matched with two thermotherapy components with different thermotherapy modes, and the thermotherapy components are divided into a first thermotherapy component 5 and a second thermotherapy component 6;
[0045] Temperature monitoring modules 7 for temperature monitoring are installed inside the heat insulation sleeve 4 at the upper and lower parts of the installation groove 8 .
[0046] The use of the applicator adopts the method of internal irradiation for radiotherapy. The hollow applicator is placed in the patient's body close to the tumor. The radiation source is guided to the patient's tumor site through a close-range radiotherapy machine. The radiation source releases rays to kill cancer cells. A large number of clinical studies have found that radiotherapy combined with hyperthermia can significantly improve the local area control rate of tumors. However, the current external hyperthermia machine has shortcomings such as being unable to be used simultaneously with radiotherapy and having a large range of inaccurate positioning. Therefore, the inventors have designed a treatment plan that combines hyperthermia and radiotherapy. An outer sleeve 3 is installed at one end of the applicator 1, and a thermotherapy element for generating heat for treatment is installed on one side of the outer sleeve 3. During radiotherapy, deep regional hyperthermia is performed by activating the temperature-controllable thermotherapy element. The combined treatment method of radiotherapy and hyperthermia has a better effect on the patient's tumor treatment.
[0047] Specifically, the method of using the applicator is a common method of tumor treatment and will not be described in detail here. It is used to treat patients with cervical cancer, but can also be used to treat patients with other cancers, such as endometrial cancer. The applicator is placed in the uterus and vaginal cavity, and the outer sleeve 3 is pressed against the surface of the cervical tumor. The radiation source inside the applicator releases radiation and simultaneously activates the first thermotherapy element 5 or the second thermotherapy element 6 on one side of the outer sleeve 3. The first thermotherapy element 5 or the second thermotherapy element 6 is selected according to the state of the tumor. During thermotherapy, the first thermotherapy element 5 or the second thermotherapy element 6 is in close contact with the tumor for treatment. The temperature monitoring module 7 is in contact with the thermotherapy element to monitor the temperature in real time for timely adjustment. It is very intelligent and ensures the treatment effect.
[0048] The heat-insulating sleeve 4 serves the purpose of heat insulation, thereby preventing the first thermotherapy component 5 or the second thermotherapy component 6 from causing damage to normal cells.
[0049] Example 2: This example is an improvement on Example 1. Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 8 Specifically, the first thermal therapy component 5 includes a first thermal radiation head 501 with an arc surface, a first heat source 502 for generating heat is installed inside the first thermal radiation head 501, and a first mounting column 503 for connection is fixedly connected to one side of the first thermal radiation head 501, and the outer side of the first mounting column 503 is fixedly connected with evenly distributed first fixing keys 504, and the first fixing keys 504 are slidingly connected to the thermal insulation sleeve 4 through the mounting groove 8, and a first fixing groove 505 is provided on the outer side of the first fixing key 504.
[0050] The second thermal treatment element 6 includes a second heat radiation head 601 having an arc-shaped surface. A second heat source 602 for generating heat is installed inside the second heat radiation head 601. A second mounting post 603 for connection is fixedly connected to one side of the second heat radiation head 601. The outer side of the second mounting post 603 is fixedly connected to uniformly distributed second fixing keys 604. The outer side of the second fixing key 604 is provided with a second fixing slot 605.
[0051] Heat insulation plates 606 are fixedly connected to the upper and lower sides of the second heat radiation head 601 .
[0052] The heat insulation board 606 is made of metal heat-insulating aluminum alloy.
[0053] During tumor treatment, the thermotherapy element is placed on the outside of the tumor, generating heat through the heat source. The temperature is controlled at 43°C, and the treatment time is controlled according to the actual situation. The first thermotherapy element 5 and the second thermotherapy element 6 can be selected according to the shape of the tumor to achieve targeted treatment.
[0054] The details are as follows:
[0055] Tumor hyperthermia utilizes physical energy to heat the tumor region, raising the temperature of the tumor tissue to an effective therapeutic temperature and maintaining it for a certain period of time. This method exploits the difference in temperature tolerance between normal tissue and tumor cells to achieve therapeutic goals. Its effects and effectiveness are primarily reflected in the following aspects: 1. Direct therapeutic effect, killing tumor cells. Hyperthermia can raise the temperature of the tumor region to above 39°C for a period of time, leading to protein denaturation and DNA damage in tumor cells, which in turn triggers apoptosis or necrosis. This physical destructive effect directly targets tumor cells, with relatively little damage to normal tissue. 2. Radiotherapy and hyperthermia have different sensitivities to cells in different phases of the cell division cycle, and the two have complementary effects. Radiation is most sensitive to the M phase (mitosis) and most resistant to the S phase (DNA synthesis), while heating is most sensitive to the S phase (DNA synthesis). 3. Heating has a greater effect on hypoxic cells that are resistant to radiation. 4. Heating can inhibit the action of DNA polymerase, making DNA damage difficult to repair, thereby inhibiting the repair of damaged tumor cells after radiotherapy.
[0056] The operation is as follows: When the tumor is flat, the second thermotherapy element 6 is selected as the thermotherapy device on one side of the outer sleeve 3. The second heat radiation head 601 is placed on the outside of the tumor. Because the second thermotherapy element 6 is provided with heat insulation plates 606 at the upper and lower ends, it is less likely to cause damage to normal cells near the heat insulation plates 606. The second heat source 602 inside the second heat radiation head 601 generates heat, using 8MHz radio frequency electromagnetic waves as the heat source, to perform deep regional hyperthermia. Each session lasts 60 minutes and is implemented within 30 minutes before the material is released into the cavity.
[0057] The heat insulation board 606 is made of heat-insulating aluminum alloy. Through its excellent heat reflection performance, it can effectively reduce the transfer of radiant heat flow and achieve the purpose of heat insulation;
[0058] When the tumor is spherical, the first thermotherapy element 5 is used as the thermotherapy device on one side of the outer sleeve 3. The first heat radiation head 501 is placed against the outside of the tumor, and the tumor covers the outside of the first radiation head 501. Because the contact surface between the first radiation head 501 and the tumor is circular, the first heat source 502 inside the first radiation head 501 generates heat, which can ensure the thermotherapy effect on the tumor. It uses 8MHz radio frequency electromagnetic waves as the heat source to perform deep regional thermotherapy. Each session lasts 60 minutes and is implemented within 30 minutes before the material is released into the cavity.
[0059] The arrangement of the second fixing key 604 and the first fixing member 504 can ensure a stable sliding connection with the outer sleeve 3 and prevent the outer sleeve 3 from rotating.
[0060] Example 3: This example is an improvement on Example 2. Figure 2 Specifically, the locking module 2 includes a fixing sleeve 201 fixedly connected to the outer sleeve 3, an outer end of the fixing sleeve 201 away from the outer sleeve 3 is provided with an external thread 202, and the fixing sleeve 201 is spirally connected to a fixing ring 205 through the external thread 202;
[0061] One end of the fixing sleeve 201 away from the outer sleeve 3 is further fixedly connected to a locking plate 203 , and the locking plate 203 is arranged at an angle.
[0062] Evenly distributed notches 204 are formed on the surfaces of the fixing sleeve 201 and the locking plate 203 .
[0063] When installing the outer sleeve 3, by fitting the notch 204 with the external thread 202, the locking plate 203 on one side of the fixing sleeve 201 is pressed toward the center to achieve close contact with the outer side of the applicator 1, thereby achieving the purpose of fixing;
[0064] The inner diameter of the fixing ring 205 is slightly smaller than the outer diameter of the fixing sleeve 201. When it cooperates with the external thread 202 on the outside of the fixing sleeve 201, it will squeeze the fixing sleeve 201. At the same time, a notch 204 is opened on the surface of the fixing sleeve 201 and the locking plate 203 to ensure that the locking plate 203 is in stable contact with the surface of the applicator 1.
[0065] Example 4: This example is an improvement on Example 3. Figure 7Specifically, the temperature monitoring module 7 includes a micro-thermocouple sensor 701 for monitoring the surface temperature of the first thermotherapy component 5 or the second thermotherapy component 6. A sliding disk 702 is fixedly connected to one side of the micro-thermocouple sensor 701. The sliding disk 702 is arranged in a circular disk, and the outer side is slidably connected to the thermal insulation sleeve 4. The other side of the sliding disk 702 is also fixedly connected to a spring 703, and the other end of the spring 703 is fixedly connected to the thermal insulation sleeve 4.
[0066] A countersunk hole 9 is also provided on the side of the thermal insulation sleeve 4, and a fixing screw 10 is provided inside the countersunk hole 9. The fixing screw 10 passes through the countersunk hole 9 to connect with the first thermotherapy component 5 or the second thermotherapy component 6.
[0067] When the first thermotherapy element 5 or the second thermotherapy element 6 is installed inside the thermal insulation sleeve 4, the micro-thermocouple sensor 701 is pushed toward the side away from the outer sleeve 3 by the action of the sliding plate 702 and the spring 703, and contacts one side of the first thermotherapy element 5 or the second thermotherapy element 6, thereby monitoring the temperature of the first thermotherapy element 5 or the second thermotherapy element 6 in real time to ensure the quality of treatment;
[0068] The micro-thermocouple sensor 701 can timely monitor the heating temperature of the first thermotherapy element 5 or the second thermotherapy element 6 to achieve precise temperature control.
[0069] When the first thermotherapy component 5 or the second thermotherapy component 6 is installed, the purpose of fixing the first thermotherapy component 5 or the second thermotherapy component 6 is achieved by inserting the fixing screw 10 into the countersunk hole 9 and cooperating with the fixing groove inside the first thermotherapy component 5 or the second thermotherapy component 6.
[0070] Example 5: This example is an improvement on Example 4. Figure 9 、 Figure 10 and Figure 11 Specifically, the outer sleeve 3 is hollow and is connected to a protective sleeve 11 on one side. A circuit for supplying power to the thermal therapy component is provided inside the protective sleeve 11.
[0071] The source applicator 1 has various states, and the outer set 3 can be individually set according to actual conditions. This application document shows two types. Figure 9 This is a structural diagram of the source device 1 passing through the outer sleeve 3. Figure 10 This is a structural diagram of the outer sleeve 3 located at the inclined end of the applicator 1, and the interior of the outer sleeve 3 is hollow and connected to a protective sleeve 11. A circuit for connecting the heat source to the power supply is installed inside the protective sleeve 11. The protective sleeve 11 serves a protective purpose to prevent the circuit from contacting the skin.

It should be pointed out that due to the limitations of textual expression, there are objectively infinite specific structures.
