Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a brachytherapy pre-installed device. Background Art

[0002] Chest wall malignant tumors are most commonly caused by chest wall metastasis of breast cancer, which is an important sign of worsening breast cancer. For this type of situation, close-range radiotherapy is a better treatment option. The reason is that the radiation source during close-range radiotherapy is closer to the tumor, and the tumor tissue receives a higher dose, while the surrounding normal tissue receives a lower dose due to the rapid drop in dose, which can achieve precise control of the tumor and effectively protect the surrounding organs.

[0003] There are many existing technologies for brachytherapy equipment, such as:

[0004] Chinese patent publication number CN115887949A discloses an angle-adjustable close-range radiotherapy positioning frame, including a base plate, an axis frame is fixed to the upper end of the base plate, a first fixed axis is fixed to the inner side of the axis frame, a lying plate is rotatably connected to the outer side of the first fixed axis, a back plate assembly is arranged at the upper end of the base plate and between the lying plate and the base plate, a leg plate assembly is also arranged at one end of the base plate away from the back plate assembly, a slide plate is arranged at one end of the base plate close to the leg plate assembly and located at the center of the base plate, a source applicator frame is fixed to the upper end of the slide plate away from the end of the base plate, and an applicator body is arranged at the upper end of the source applicator frame.

[0005] It can be seen that most close-range radiotherapy equipment adjusts the body position to facilitate the insertion and placement of the applicator's implant needle. However, for chest wall malignant tumors, due to the metastasis of breast cancer to the chest wall, multiple tumor masses will appear on the surface and inside of the chest. The irregular structure of the chest wall determines that if close-range radiotherapy is performed, the applicator needs to be close to the skin, or inserted into the tumor lesion in the form of an implant needle. However, with current technology, it is impossible to determine the location, range and infiltration depth of the chest wall tumor based on experience. At the same time, even if the implant needle is inserted, there is no effective measure to fix the implant needle during the treatment process.

[0006] In view of this, we propose a brachytherapy pre-installed device. Summary of the invention

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example

[0037] Currently, most close-range radiotherapy equipment adjusts the body position to facilitate the insertion and placement of the applicator's implant needle. However, for chest wall malignant tumors, due to the metastasis of breast cancer to the chest wall, multiple tumor masses will appear on the surface and inside of the chest. The irregular structure of the chest wall determines that if close-range radiotherapy is performed, the applicator needs to be close to the skin, or inserted into the tumor lesion in the form of an implant needle. However, with current technology, it is impossible to determine the location, range and infiltration depth of the chest wall tumor based on experience. At the same time, even if the implant needle is inserted, there is no effective measure to fix the implant needle during the treatment process.

[0038] Therefore, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the purpose of this embodiment is to provide a brachytherapy pre-installed device, which includes a frame 100, a fixing assembly 200 and a placement assembly 300; considering that the brachytherapy surgery requires ultrasound detection of the tumor position during the operation, the fixing assembly 200 includes a bracket 201 and a sleeve 205, the bracket 201 is slidably connected to the frame 100, the sleeve 205 is slidably connected to the bracket 201, the sleeve 205 fixes the ultrasound probe and drives the ultrasound probe to move, the ultrasound probe is fixed in the sleeve 205, the relative position relationship between the sleeve 205 and the bracket 201 and the bracket 201 and the frame 100 is adjusted, thereby adjusting the position of the ultrasound probe, so as to detect the tumor in the frame 100 and guide the subsequent implantation needle;

[0039] After ultrasonic detection of the tumor, the implantation needle of the source applicator needs to be inserted into the tumor and fixed. Therefore, the placement component 300 includes a rubber frame 301 and a placement frame component 310 that matches the number of detected tumors. The rubber frame 301 is detachable and is installed in the frame 100 by utilizing the elasticity of the material of the rubber frame 301. The placement frame component 310 is slidably connected to the rubber frame 301 so that the position of the placement frame component 310 can be adjusted according to the detection results of the ultrasonic probe. At the same time, the implantation needle is fixed while the source end of the implantation needle is inserted into the tumor, thereby solving the problem of implantation needle fixation.

[0040] Considering the installation of the bracket 201 and the rubber frame 301, through slots 101 are symmetrically provided on both sides of the frame 100, and the bracket 201 and the rubber frame 301 are both installed in the frame 100 through the through slots 101. At the same time, U-shaped fixing blocks 203 are fixed at both ends of the bracket 201, and the bracket 201 forms a sliding connection with the frame 100 through the fixing blocks 203. Considering that the bracket 201 may shake when the ultrasonic probe is moved, a locking device 204 is threadedly connected to one side of the fixing block 203. After the bracket 201 is adjusted to a corresponding position, the locking device 204 is rotated to make the bracket 201 immobile, thereby avoiding the shaking phenomenon caused by the movement of the ultrasonic probe;

[0041] In order to facilitate the movement of the ultrasonic probe, a first slide groove 202 is provided in the bracket 201, and the sleeve 205 includes a support frame 206 and a sleeve 207. The support frame 206 is slidably connected to the first slide groove 202, and the sleeve 207 is fixed in the support frame 206. The ultrasonic probe is sleeved in the sleeve 207, and the support frame 206 is pushed to slide in the first slide groove 202, so that the movement of the ultrasonic probe can be realized:

[0042] Similarly, in order to facilitate the movement of the placement rack assembly 310, the rubber rack 301 is also provided with a through groove 101, and the two sides of the through groove 101 of the rubber rack 301 are respectively provided with a second slide groove 302 and a third slide groove 303, and the cross-section of the second slide groove 302 is a folding shape; the placement rack assembly 310 includes a fixed rack 311, one end of the fixed rack 311 is a folding shape, and the two ends of the fixed rack 311 are respectively installed in the second slide groove 302 and the third slide groove 303, and the folded end of the fixed rack 311 extends outward through the second slide groove 302 to form a push rod, and the moving direction of the placement rack assembly 310 is limited by the folded second slide groove 302 and the folded end of the fixed rack 311. At the same time, the folded end of the fixed rack 311 extends outward to become a push rod, which is convenient for medical staff to apply external force to push the placement rack assembly 310;

[0043] Since there is an angle deviation between the tumor detected by the ultrasound probe and the direction in which the rubber sleeve 314 in the placement frame assembly 310 faces, please refer to Figure 6As shown, the fixing frame 311 is rotatably connected to the fixing plate 312, and a fixing ring 313 is fixed to one end of the fixing plate 312 away from the fixing frame 311, and a rubber sleeve 314 is sleeved on the outside of the fixing ring 313. When the ultrasound probe detects a tumor, the fixing frame 311 is rotated to drive the rubber sleeve 314 to adjust its angle, so that the rubber sleeve 314 is aligned with the tumor;

[0044] If the fixing frame 311 cannot be fixed after rotation, the rubber sleeve 314 cannot maintain the adjusted angle. Therefore, one side of the fixing plate 312 is rotatably connected to one end of the fixing frame 311 with a telescopic rod 315, which can be achieved by adjusting the telescopic rod 315. It should be noted that the telescopic rod 315 in this embodiment is in the form of a sleeve rod, a sliding rod and a pressing ball. Specifically, the sliding rod is slidably connected in the sleeve rod, and a retractable pressing ball is installed on one side of the sliding rod. A plurality of through holes are provided on one side of the sleeve rod, and the pressing ball is engaged with the through holes.

[0045] Considering the convenience of adjusting and fixing the frame 100, therefore, please refer to Figure 2 and Figure 3 As shown, a fixing column 102 is fixed to the outside of the frame 100, and a support rod 400 for adjusting the frame 100 is externally connected to the fixing column 102. A joint 110 is provided between the support rod 400 and the fixing column 102. By adjusting the external support rod 400, the position of the frame 100 is adjusted, so that it is convenient for doctors to adjust the position of the frame 100 according to the area of ​​the patient's tumor before surgery, and the stability of the frame 100 is ensured during surgery;

[0046] Furthermore, the connector 110 is disclosed: the connector 110 includes a shell 111, one end of the shell 111 is an open end, and the shell 111 is sequentially installed with a clamping jaw 114, a pushing member 113 and a spring 115 from the open end inward, the clamping jaw 114 is sleeved with the fixed column 102, the shell 111 is symmetrically provided with a limiting groove 112, and the pushing member 113 is symmetrically provided with a pushing rod, wherein the pushing rod is slidably connected to the limiting groove 112, when the pushing member 113 is pushed by the pushing rod to make the clamping jaw 114 extend from the open end of the shell 111, the clamping jaw 114 opens, and the clamping jaw 114 is sleeved on the fixed column 102, and the pushing rod is released. Under the elastic force of the spring 115, the clamping jaw 114 retracts into the shell 111, thereby sleeved and fixed the fixed column 102.

[0047] In summary, the working principle of this solution is as follows:

[0048] Push the push rod to fix the connector 110 to the fixed column 102, adjust the external support rod 400, adjust the position of the frame 100, and start the equipment pre-installation after the frame 100 reaches the predetermined position. After installing the rubber frame 301 on one side of the frame 100, adjust the bracket 201 so that one side of the bracket 201 is against the rubber frame 301, rotate the locker 204 to fix the bracket 201, insert the ultrasound probe into the sleeve 207, and at the same time, take a number of placement frame assemblies 310 and install them in the rubber frame 301, push the support frame 206 to slide in the first slide groove 202, and drive the ultrasound probe to detect. When the tumor is detected, move a placement frame assembly 310, and adjust the angle of the rubber sleeve 314 through the telescopic rod 315 so that the axis of the rubber sleeve 314 is aligned with the center area of ​​the tumor, take the implant needle, and after the implant needle is inserted into the tumor through the rubber sleeve 314, through the limit of the rubber sleeve 314 itself and The source end of the implant needle is fixed, thereby ensuring the fixation of the implant needle; repeat the above-mentioned ultrasound probe detection, movement and adjustment of the placement frame assembly 310, and insertion of the implant needle, until the support frame 206 slides to the end of the first slide groove 202, rotate the locker 204 to loosen the bracket 201, move the bracket 201 downward, and then take a rubber frame 301 and install it on one side of the previous rubber frame 301, then adjust the bracket 201 so that one side of the bracket 201 is against the rubber frame 301, rotate the locker 204 to fix the bracket 201, and repeat the above-mentioned ultrasound probe detection, movement and adjustment of the placement frame assembly 310, and insertion of the implant needle, until all the implant needle fixing operations are completed.
