Abstract
Description
Technical Field
[0001] This invention relates to a radiator for cervical treatment, and more particularly to a directional radiator for intracavitary treatment of cervical cancer. Background Technology
[0002] In the treatment of cervical cancer, because cervical cancers are located near the cervical os behind the vagina, and more often within the cervical canal, current treatment options mainly include radiotherapy and microwave radiation therapy. Currently, the most commonly used treatment equipment is the cervical radiator, which has a rounded head structure. The microwave radiation unit inside the rounded head structure acts directly on the cervical os area, and the microwave radiation penetrates to the tumor.
[0003] However, the cervical radiators currently in use have a simple structure. The round-headed cylindrical structure does not conform to the structure of the human vagina, causing the cylindrical radiator to easily shift position within the vagina. Furthermore, prolonged placement and treatment within the vagina can cause discomfort for patients, especially in the narrower anterior vaginal cavity and vaginal opening. In addition, current radiators directly radiate the cervical opening area, which is effective for treating tumors on the surface of the cervix near the cervical opening. However, tumors closer to the uterine cavity within the cervix require longer periods and higher doses of radiation. Moreover, the radiation therapy does not target the tumor, causing other normal tissues to also be affected by microwave radiation, resulting in a longer self-healing time.
[0004] Therefore, it is necessary to develop a directional radiator for intracavitary treatment of cervical cancer to solve the above problems. Summary of the Invention
[0005] In order to overcome the shortcomings of current radiators that are not ergonomic, causing patient discomfort and generalized radiation therapy that damages other tissues, the purpose of this invention is to provide an ergonomic radiator for intracavitary treatment of cervical cancer that reduces patient discomfort and provides directional radiation to the lesion area, minimizing the impact on other tissues.

[0007] Preferably, the neck insertion assembly includes a rigid tube, which is fixedly connected between the moving parts of the first electric slide rail, and a flexible tube is fixedly connected to the upper end of the rigid tube.
[0008] Preferably, the attitude adjustment component includes a connecting frame, which is fixedly connected to the left side of the moving part of the second electric slide rail.

[0010] Preferably, the radiating assembly includes a mounting compartment, which is fixedly connected to the upper side of the mounting ring. Maintaining rings are fixedly connected to both the upper and lower sides of the mounting compartment. A metal rectangular microwave radiating antenna is fixedly installed inside the mounting compartment. An internal radio frequency (RF) connection line is fixedly connected to the lower side of the metal rectangular microwave radiating antenna. The RF connection line passes through the interior of the corrugated flexible shaft and passes through the rotating ring and connecting frame to connect to the upper end of the storage tray line. A mounting cover is fixedly connected to the left side of the mounting compartment.
[0011] Preferably, it also includes a visual component, which is disposed at the cervical shell. The visual component is used by medical personnel to visually and precisely control the insertion of the tubing into the patient's cervical canal. The visual component includes a tempered glass layer. A tempered glass layer is installed on the upper outer layer of the cervical shell.

[0015] 2. This invention addresses the angle between the cervix and vagina in the human body. By using a first electric slide rail to move a rigid tube upwards, a flexible tube is inserted into the cervix. This method allows the flexible tube to be smoothly positioned within the cervix, reducing patient discomfort. Furthermore, the installation of a radiation component within the flexible tube, through an adjustment and reversing component, allows for precise targeting of the lesion area within the cervix.

This allows the metal rectangular microwave radiation antenna to deliver targeted microwave radiation based on the tumor structure within the patient's cervical canal, further reducing damage to other normal tissues from microwave radiation and minimizing the patient's fear when receiving microwave radiation therapy.

Detailed Implementation
[0035] The present invention will now be described in detail with reference to the accompanying drawings.
[0036] Example 1, as Figures 1-6As shown, a directional radiator for intracavitary treatment of cervical cancer includes an outer shell 1, an inner shell 2, a cervical opening shell 3, an end cap 4, an external radio frequency connection cable 5, a storage tray cable 6, a first electric slide rail 7, a second electric slide rail 8, a cervical insertion assembly 9, an attitude adjustment assembly 10, a reversing assembly 11, and a radiation assembly 12. The outer shell 1 is a recessed circular cavity structure. The inner shell 2 is used to extend into the anterior cavity of the vagina. The anterior cavity position and the narrow structure of the vaginal opening fit the recessed structure of the outer shell 1. The upper side of the outer shell 1 is connected to the inner shell 2 by a sealing thread. The inner shell 2 is an outwardly expanding circular cavity structure. The inner shell 2 is used to extend into the vaginal cavity near the cervical opening. The larger structure of the vaginal cavity fits the inner cavity. The outward expansion structure of the shell 2 maintains the stability of the inner shell 2 within the pelvic cavity. The outer layers of the inner shell 2 and the outer shell 1 form a uniformly transitioning arc-shaped structure. The overall structure composed of the inner shell 2 and the outer shell 1 conforms to the vaginal structure, ensuring that the inner shell 2 and the outer shell 1 are fully fitted within the vaginal structure and maintain positional stability. This structure conforms to ergonomic requirements, not only maintaining stability within the vagina but also reducing discomfort and improving patient comfort during treatment. The upper side of the inner shell 2 is connected to the neck shell 3 via a sealed thread. The neck shell 3 is a centrally open cavity structure with a rounded top. The structure includes a rounded head of the neck housing 3 for easy insertion into the patient's vagina. An end cap 4 is connected to the lower side of the outer housing 1 via a sealed thread. An external radio frequency (RF) connection cable 5 is fixedly installed at the center of the lower side of the end cap 4. The RF connection cable 5 connects to an external microwave radiation host and extends into the end cap 4. A storage coil cable 6 is placed inside the end cap 4 in a spiral pattern, with its lower end fixedly connected to the RF connection cable 5. First electric slide rails 7 are fixedly connected to the front and rear sides of the inner wall of the inner housing 2. The first electric slide rail 7 is a servo-controlled screw-driven type track pair. A second electric slide rail 8 is fixedly connected to the right side of the inner wall of the inner housing 2. The second electric slide rail 8 is also a servo-controlled screw-driven type track pair. A cervical insertion assembly 9 is provided between the cavity structures of the shell 2 and the outer cavity shell 1. The cervical insertion assembly 9 is fixedly connected to the moving part of the first electric slide rail 7. Controlling the operation of the first electric slide rail 7 will cause the cervical insertion assembly 9 to move up and down. The cervical insertion assembly 9 is used to insert into the patient's cervix. An attitude adjustment assembly 10 is provided inside the cervical insertion assembly 9. The attitude adjustment assembly 10 is fixedly connected to the moving part of the second electric slide rail 8. Controlling the operation of the second electric slide rail 8 will cause the attitude adjustment assembly 10 to move up and down within the cervical insertion assembly 9. A reversing assembly 11 is provided at the attitude adjustment assembly 10. A radiation assembly 12 is provided at the position of the attitude adjustment assembly 10 within the cervical insertion assembly 9. The radiation assembly 12 is electrically connected to the storage tray line 6 through a wire harness. The radiation assembly 12 is used to perform microwave radiation therapy on lesions in the patient's cervix.The posture adjustment component 10 is used to adjust the height position of the radiation component 12 within the cervical insertion component 9, and the reversing component 11 is used to adjust the angle of the radiation component 12 within the cervical insertion component 9. The posture adjustment component 10 and the reversing component 11 work together to ensure that the radiation component 12 is precisely positioned facing the lesion within the patient's cervix, enabling the radiation component 12 to provide precise radiation therapy to the lesion. While the posture adjustment component 10 adjusts the position of the radiation component 12, the cable reel 6 ensures the traction length of the radiation component 12 cable bundle.
[0037] like Figures 6-10 As shown, the cervical insertion assembly 9 includes a rigid tube 91 and a flexible tube 92. The rigid tube 91 is fixedly connected between the moving parts of the first electric slide rail 7. The rigid tube 91 is a rigid pipe structure with elongated through holes on both sides. The rigid tube 91 is located inside the outer cavity shell 1. The upper end of the rigid tube 91 is fixedly connected to the flexible tube 92. The upper end of the flexible tube 92 has a rounded closed structure. The rounded closed structure at the upper end of the flexible tube 92 is used to smoothly extend into the patient's cervix. The flexible tube 92 is located inside the inner cavity shell 2. The flexible tube 92 is used to extend into the patient's cervix as a whole. Because there is an angle between the cervical canal and the vaginal structure, the flexible tube 92 can be smoothly positioned inside the patient's cervical canal. When the first electric slide rail 7 is activated, the first electric slide rail 7 will drive the rigid tube 91 and the flexible tube 92 to move upward as a whole, so that the flexible tube 92 enters the patient's cervical opening through the central opening of the cervical shell 3, so that the flexible tube 92 is completely inside the patient's cervical canal. At this time, the rigid tube 91 is inside the inner cavity shell 2.
[0038] like Figures 11-13As shown, the attitude adjustment component 10 includes a connecting frame 101, an annular slide rail 102, a rotating ring 103, a corrugated flexible shaft 104, and a mounting ring 105. The connecting frame 101 is fixedly connected to the left side of the moving part of the second electric slide rail 8. The connecting frame 101 is located inside the rigid tube 91, between the left and right elongated openings of the rigid tube 91. The reversing component 11 is located on the left side of the connecting frame 101. When the first electric slide rail 7 moves the rigid tube 91, the rigid tube 91 moves through its elongated through-hole structure at the connecting frame 101. When the second electric slide rail 8 moves the connecting frame 101, the connecting frame 101 moves through the elongated through-hole structure of the rigid tube 91. The annular slide rail 102 is fixedly connected to the upper side of the connecting frame 101. The rotating ring 103 is fixedly connected to the moving part of the annular slide rail 102. The upper side of the rotating ring 103... A corrugated flexible shaft 104 is fixedly connected inside the flexible tube 92. The corrugated flexible shaft 104 is used to rotate at an angle inside the flexible tube 92. The corrugated flexible shaft 104 has a ring-shaped structure. An installation ring 105 is fixedly connected to the upper end of the corrugated flexible shaft 104. The radiation component 12 is located on the upper side of the installation ring 105. After the flexible tube 92 is inside the patient's cervical canal, the second electric slide rail 8 is activated. The second electric slide rail 8 will drive the connecting frame 101 to move up and down, so that the connecting frame 101 drives the ring slide rail 102, the rotating ring 103, the corrugated flexible shaft 104 and the installation ring 105 to move up and down. The connecting frame 101 moves inside the rigid tube 91 through its elongated through-hole structure, so that the radiation component 12 moves up and down inside the flexible tube 92, so that the radiation component 12 moves to the lesion position inside the patient's cervical canal.
[0039] like Figures 11-12As shown, the reversing assembly 11 includes a drive motor 111, a drive gear 112, and a ring gear 113. The drive motor 111 is fixedly connected to the left side of the connecting frame 101. The drive motor 111 is a servo-controlled motor. The drive gear 112 is fixedly connected to the upper end of the output shaft of the drive motor 111. The ring gear 113 is fixedly connected to the outer layer of the rotating ring 103. The ring gear 113 meshes with the drive gear 112. After the tubing 92 is placed in the patient's cervical canal, and the radiation assembly 12 is positioned at the lesion location in the patient's cervical canal via the second electric slide rail 8, the drive motor 111 is started. The drive motor 111 will drive the ring gear 112 through the drive gear 112. The rotation of wheel 113 causes the ring gear 113 to drive the rotating ring 103 to rotate, which in turn causes the corrugated flexible shaft 104 to rotate at an angle. This, in turn, causes the corrugated flexible shaft 104 to drive the radiation component 12 to rotate, allowing the radiation component 12 to adjust its angle and face the lesion in the cervix. This allows the radiation component 12 to be directed to the lesion in the cervical canal. After that, the radiation component 12 can be turned on to perform targeted radiation therapy on the lesion in the cervical canal. By adjusting the radiation component 12 to precisely face the lesion, the radiation component 12 can perform precise targeted therapy on the lesion, avoiding the side effects of radiation on normal tissues in other parts of the cervix.
[0040] like Figures 12-15As shown, the radiating assembly 12 includes a mounting compartment 121, a sustaining ring 122, a metal rectangular microwave radiating antenna 123, an RF internal connecting wire 124, and a mounting cover 125. The mounting compartment 121 is fixedly connected to the upper side of the mounting ring 105. The mounting compartment 121 is located inside the flexible tube 92 above the mounting ring 105. The mounting compartment 121 has a left-side open structure. Sustaining rings 122 are fixedly connected to both the upper and lower sides of the mounting compartment 121. The sustaining rings 122 are annular structures with surface grooves. The outer diameter of the sustaining rings 122 is slightly smaller than the inner diameter inside the flexible tube 92. The sustaining rings 122 are used to maintain the positional stability of the mounting compartment 121 inside the flexible tube 92 and prevent the mounting compartment 121 from shaking inside the flexible tube 92. A metal rectangular microwave radiating antenna 123 is fixedly installed inside the mounting compartment 121. A rectangular microwave radiating antenna 123 is fixedly connected to the lower side of the metal rectangular microwave radiating antenna 123. The RF internal connection line 124 passes through the lower side of the mounting compartment 121, passes through the inside of the corrugated flexible shaft 104, passes through the rotating ring 103 and the connecting frame 101, and connects to the upper end of the receiving tray line 6. The RF internal connection tube is fixedly connected to the rotating ring 103. A mounting cover 125 is fixedly connected to the left side of the mounting compartment 121. The mounting cover 125 has an open structure on the left side. The mounting compartment 121 and the mounting cover 125 are made of tungsten alloy. The tungsten alloy material of the mounting compartment 121 and the mounting cover 125 is used to prevent the microwave radiation of the metal rectangular microwave radiating antenna 123 from reaching the area of its non-open structure. The metal rectangular microwave radiating antenna 123 radiates outwards only towards the open structure on the left side of the mounting compartment 121. This method protects normal tissues in other parts of the patient's cervix from the side effects of radiation. When the radiating assembly 12 moves up and down and rotates via the corrugated flexible shaft 104, the mounting compartment 121 rotates, causing the metal rectangular microwave radiating antenna 123 inside the mounting compartment 121 to rotate as well. This positions the metal rectangular microwave radiating antenna 123 at the lesion site in the cervical canal and towards that lesion area. At this time, the power supply to the external microwave radiating host and the metal rectangular microwave radiating antenna 123 can be turned on, allowing the external microwave radiating host to act on the metal rectangular microwave radiating antenna 123, causing the metal rectangular microwave radiating antenna 123 to radiate outwards. Microwave radiation allows the metal rectangular microwave radiation antenna 123 to precisely treat lesions within the cervical canal. The antenna delivers microwave radiation to the lesions, damaging malignant tissue in the lesion area. The radiation also causes high-frequency oscillations of polar ions and molecules within the lesion's biological cells, resulting in electromagnetic energy being converted into heat energy through friction and collision. This raises the local temperature of the lesion area to a certain level, killing or inhibiting tumor cell proliferation. Simultaneously, the high temperature promotes capillary dilation and increased permeability, enhancing blood circulation and metabolism, strengthening the phagocytic activity of white blood cells, inhibiting bacterial growth, and accelerating tissue regeneration. This results in therapeutic effects such as promoting wound healing, reducing inflammation, swelling, and pain, thereby achieving the therapeutic goal.
[0041] like Figure 5 and Figure 17 As shown, it also includes a visual component 13, which includes a tempered glass layer 131, a fixing ring 132, a low-light lamp assembly 133, and an endoscope 134. The visual component 13 is located at the cervical shell 3. The visual component 13 is used by medical personnel to visually and precisely control the insertion of the flexible tube 92 into the patient's cervical canal. The tempered glass layer 131 is installed on the upper outer layer of the cervical shell 3. The fixing ring 132 is fixedly connected inside the cavity of the cervical shell 3. The low-light lamp assembly 133 is fixedly connected in an array on the outer layer of the fixing ring 132. The low-light lamp assembly 133 is used to illuminate the cervical structure inside the vagina through the tempered glass layer 131. The endoscope 134 is fixedly connected to the left side of the outer layer of the fixing ring 132. The endoscope 134 is used to observe the cervical structure inside the illuminated vagina, which facilitates the precise control of the movement of the outer shell 1 and the inner shell 2 by medical personnel, so that the flexible tube 92 can be accurately inserted into the patient's cervical canal.
[0042] like Figure 16 As shown, it also includes a radiation-limiting plate 14, which is fixedly connected to the left side of the mounting compartment 121. The radiation-limiting plate 14 is a 3D-printed structure, consisting of tungsten alloy panels of varying thicknesses. Based on the tumor structure of the patient's lesion area, the radiation scheme of the metal rectangular microwave radiation antenna 123 for that tumor structure can be tailored. Specifically, based on the tumor structure, for smaller areas of the tumor structure, a tungsten alloy surface layer of the radiation-limiting plate 14 of appropriate thickness is designed. This allows the microwave radiation from the metal rectangular microwave radiation antenna 123 to pass through the tungsten alloy panel of appropriate thickness, reducing the radiation amount and allowing microwave radiation to reach smaller areas of the tumor structure, further reducing excessive microwave penetration. Microwave radiation is applied to the cervical tumor tissue, further reducing the damage to other normal tissues caused by microwave radiation. For locations with larger tumor structures, a thinner tungsten alloy panel can be designed or omitted altogether, allowing the microwave radiation from the metal rectangular microwave radiation antenna 123 to pass through the radiation-limiting plate 14 and deliver normal or higher radiation levels to the smaller tumor structures. In this way, the metal rectangular microwave radiation antenna 123 can provide targeted microwave radiation based on the tumor structure within the patient's cervical canal, further reducing damage to other normal tissues and lessening the patient's fear when receiving microwave radiation therapy.
[0043] like Figure 15As shown, it also includes a thermal radiation module 15, which is fixedly connected to the upper and lower sides of the left side of the installation chamber 121. After the thermal radiation module 15 is activated, it can further expand the heating area of the lesion area of the cervical canal, further expand the capillary dilation of the lesion area, enhance permeability, further promote blood circulation and metabolism, enhance the phagocytic function of white blood cells, inhibit bacterial growth, and accelerate tissue regeneration, thereby having the therapeutic effects of promoting incision healing, reducing inflammation, reducing swelling, and relieving pain.
[0044] Example 2, as Figures 1-17 As shown, the preparation work before using the directional radiator for intracavitary treatment of cervical cancer is as follows: ① Clean, disinfect and sterilize the internal and external components of the directional radiator for intracavitary treatment of cervical cancer; ② Arrange the storage coil 6 into a spiral coil inside the end cap 4; ③ Connect the radio frequency external connection cable 5 to the external microwave radiation host and test the machine.
[0045] The positioning of the directional radiator for intracavitary treatment of cervical cancer within the patient's cervix involves the following steps: ① An abdominal ultrasound examination is performed to determine the specific location of the lesion within the cervical canal; ② The directional radiator is inserted deep into the patient's cervix, and the metal rectangular microwave radiating antenna 123 is simultaneously switched to low-power mode, creating a strong echo zone in the metal rectangular microwave radiating antenna 123 during the ultrasound examination. By ensuring that the strong echo zone of the metal rectangular microwave radiating antenna 123 coincides with the lesion area during ultrasound examination, the orientation of the metal rectangular microwave radiating antenna 123 can be achieved.
[0046] Preparation for inserting the directional radiator for intracavitary treatment of cervical cancer into the cervical canal of the patient: ① Clean the patient's vagina and cervical os; ② Apply human lubricant to the vaginal wall and cervical os; ③ Insert the inner shell 2 of the directional radiator for intracavitary treatment of cervical cancer into the patient's vagina, so that the inner shell 2 and the outer shell 1 of the directional radiator for intracavitary treatment of cervical cancer are together inside the patient's vagina, and the cervical os shell 3 is positioned at the cervical os.
[0047] The treatment method of this directional radiator for endovascular treatment of cervical cancer on cervical canal lesions is as follows: ① Control the first electric slide rail 7 to insert the flexible tube 92 into the patient's cervical canal; ② Control the second electric slide rail 8 to move the radiation component 12 up and down within the flexible tube 92, so that the metal rectangular microwave radiation antenna 123 of the radiation component 12 is at the same level as the lesion area in the patient's cervical canal; ③ Control the drive motor 111 to orient the metal rectangular microwave radiation antenna 123 of the radiation component 12 toward the lesion in the cervical canal; ④ Turn on the external microwave radiation host and the metal rectangular microwave radiation antenna 123, so that the metal rectangular microwave radiation antenna 123 can perform directional microwave radiation on the patient's lesion area, thereby performing treatment.
