Description

Technical Field

[0001] This invention relates to the field of medical auxiliary devices, and more particularly to a protective device for intracavitary radiotherapy of gynecological tumors. Background Technology

[0002] Intracavitary radiotherapy for gynecological tumors, also known as brachytherapy or afterloading therapy, is a method of treatment that involves placing a radiation source directly into or near the tumor site. This method can provide a high dose of radiation while minimizing the impact on surrounding healthy tissues. To further prevent the impact on surrounding healthy tissues, current technologies generally use an airbag to shield the radiation source and reduce radiation effects. However, in existing devices, the positions of the airbag and the radiation source are relatively fixed. When the device is inserted into the patient's body for treatment, the positions of the airbag and the radiation source cannot be flexibly adjusted accordingly. This can lead to incomplete shielding, which in turn affects surrounding healthy tissues. In addition, since the airbag needs to enter the body along with the device, friction from the internal tissues may cause wrinkles on the surface of the airbag, resulting in incomplete inflation and weakened protective effect.

[0003] Therefore, in order to address the above problems, a protective device for intracavitary radiotherapy of gynecological tumors is now being developed. Summary of the Invention

[0004] To overcome the shortcomings of existing devices where the positions of the airbag and the application source are relatively fixed, and cannot be flexibly adjusted when entering the patient's body for treatment, resulting in incomplete protection and impacting surrounding healthy tissues, and because the airbag needs to enter the body along with the device, friction from internal tissues may cause wrinkles on the airbag surface, leading to incomplete inflation and weakened protective effect, this invention provides a protective device for intracavitary radiotherapy of gynecological tumors.

[0005] The technical solution of this invention is: a protective device for intracavitary radiotherapy of gynecological tumors, comprising:

[0006] Applicator;

[0007] A connector is provided at the right end of the applicator;

[0008] The application source, wherein the application source device is located at the left end;

[0009] An extension frame, which is slidably mounted on the applicator;

[0010] An airbag is disposed on the left side of the extension frame and is used to shield and protect the application source.

[0011] An air outlet assembly is disposed on the extension frame and is used to inflate the airbag.

[0012] Furthermore, it also includes a housing, which is located on the upper right side of the extension frame. A servo motor is mounted on the housing, and the output shaft of the servo motor is oriented forward. A rotating wheel is connected to the output shaft of the servo motor, and multiple grooves are formed on the air outlet assembly.

[0013] Furthermore, it also includes a visual component, which is located at the left end of the air outlet component. The visual component is used to assist medical personnel in observing the folds inside the airbag. A control line is connected to the right side of the visual component and is attached to the upper part of the air outlet component.

[0014] Furthermore, it also includes a connecting rod, which is connected to the right side of the extension frame, and the actuating frame is connected between the connecting rods.

[0015] Furthermore, it also includes a rotating rod, which is rotatably disposed on the upper right side of the extension frame. An extrusion member is installed on the rotating rod, and the extrusion member is used to actively extrude and isolate the air outlet assembly. A toggle lever is connected to the top of the extrusion member.

[0016] Furthermore, it also includes a scale element, which is disposed on the front side of the applicator.

[0017] Furthermore, each of the rotating wheels has a protrusion that can engage with the corresponding groove.

[0018] Furthermore, each of the toggle frames is equipped with a power assist lever at its bottom.

[0019] Furthermore, each of the toggle levers is equipped with a spherical assist block.

[0020] Furthermore, an inspection point is provided on the front side of the extension frame, and the inspection point and the scale piece are used together to determine the movement length of the airbag.

[0021] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0022] 1. Once the treatment source reaches the lesion location, pull the extension frame to adjust the position of the airbag, so that the airbag can cover and block the treatment source, preventing incomplete blocking of the treatment source. Then, control the air outlet component to inflate the airbag. During the inflation process, the visual component is operated through the control line to observe the folds inside the airbag. Based on the folds, the servo motor drives the rotating wheel to rotate, causing the air outlet component to move. When the air outlet port of the air outlet component is aligned with the fold position and inflated, it avoids incomplete inflation of the airbag, which would weaken the protective effect.

[0023] 2. When inflating the airbag through the air outlet assembly, medical staff can actively push the lever to quickly squeeze and block the air outlet assembly's pipes, preventing gas from entering the airbag. This improves operational flexibility and also avoids the inability to quickly stop air supply in case of malfunction in the air outlet assembly, thus improving operational safety.

Detailed Implementation

[0033] The present invention will now be described in detail with reference to the accompanying drawings.

[0034] Example 1

[0035] A protective device for intracavitary radiotherapy of gynecological tumors, such as Figures 1-8As shown, it includes an applicator 1, a connector 2 on the right side of the applicator 1, an applicator head 3 on the left side of the applicator 1, an extension frame 6 that slides on the applicator 1, an airbag 4 on the left side of the extension frame 6, the airbag 4 is used to shield and protect the applicator head 3, and an air outlet component 5 is provided on the extension frame 6, the air outlet component 5 is used to inflate the airbag 4.

[0036] It also includes a housing 7, which is located on the upper right side of the extension frame 6. A servo motor 8 is mounted on the housing 7. The output shaft of the servo motor 8 is oriented forward. A rotating wheel 9 is connected to the output shaft of the servo motor 8. Multiple grooves 10 are opened on the air outlet assembly 5. Each rotating wheel 9 has a protrusion, and each protrusion can engage with the corresponding groove 10.

[0037] It also includes a visual component 11. The left end of the air outlet component 5 is provided with a visual component 11. The visual component 11 is used to assist medical staff in observing the folds inside the airbag 4. The right side of the visual component 11 is connected to a control line 12, which is attached to the upper part of the air outlet component 5.

[0038] It should be noted that during gynecological tumor implantation radiotherapy, in order to avoid damage to other non-lesion sites caused by the radioactive rays generated by the implantation source 3, this device can be used in conjunction with the implantation source 3 to block the implantation source 3. First, determine the location of the patient's lesion, and then insert the device into the patient's body. When the implantation source 3 reaches the lesion location, pull the extension frame 6 to adjust the position of the airbag 4, so that the airbag 4 can cover and block the implantation source 3, preventing the implantation source 3 from being incompletely blocked. Then, control the air outlet component 5 to inflate the airbag 4. During the inflation process, operate the visual component 11 through the control line 12 to observe the folds inside the airbag 4, and then control the servo motor 8 to drive the rotating wheel 9 to rotate according to the folds, so that the air outlet component 5 moves. When the air outlet port of the air outlet component 5 can be aligned with the fold position and inflated, it can prevent the airbag 4 from being incompletely inflated and weakening the protective effect.

[0039] Example 2

[0040] Based on embodiment 1, it also includes a connecting rod 13. The right side of the extension frame 6 is connected with symmetrical connecting rods 13. A toggle frame 14 is connected between the connecting rods 13. Each toggle frame 14 is provided with a power assist paddle at its bottom.

[0041] It should be noted that when the extension frame 6 needs to be pulled, it is difficult to pull because the extension frame 6 is too close to the source device 1. In this case, the auxiliary lever at the bottom of the lever 14 can be pulled to make the lever 14 pull the extension frame 6 to move, so that the extension frame 6 can quickly drive the airbag 4 to adjust its position, thus improving the ease of operation.

[0042] It also includes a rotating rod 15. Two rotating rods 15 are rotatably arranged on the upper right side of the extension frame 6. Each rotating rod 15 is equipped with an extrusion component 16. The extrusion component 16 is used to actively extrude and isolate the air outlet assembly 5. Each extrusion component 16 is connected to a toggle rod 17, and each toggle rod 17 is equipped with a spherical assist block.

[0043] It should be noted that when inflating the airbag 4 through the air outlet component 5, medical staff can actively push the lever 17 to cause the squeezing component 16 to quickly squeeze and block the pipe of the air outlet component 5, preventing gas from continuing to enter the airbag 4. This improves the flexibility of operation and also avoids the inability to quickly stop the air supply if the air outlet component 5 malfunctions, thus improving operational safety.

[0044] It also includes a scale element 18. The scale element 18 is provided on the front side of the applicator 1, and the inspection point is provided on the front side of the extension frame 6. The inspection point and the scale element 18 work together to determine the movement length of the airbag 4.
