Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a compact, portable superficial radiotherapy device. Background Technology

[0002] Superficial radiotherapy is a type of medical device specifically designed to treat superficial tumors and some benign lesions. Its core principle is to use ionizing radiation to locally irradiate the diseased tissue, thereby destroying the DNA structure of cancer cells, inhibiting their proliferation, and inducing apoptosis, thus controlling or eliminating the lesion. In clinical applications, it is widely used to treat skin cancer, basal cell carcinoma, squamous cell carcinoma, and benign lesions such as keloids and hemangiomas. Compared to surgical excision, superficial radiotherapy has advantages such as minimal trauma, less damage to surrounding normal tissues, and faster patient recovery, preserving tissue shape and function to the greatest extent possible, and significantly improving the patient's quality of life.

[0003] The compact portable superficial radiotherapy unit is a new type of equipment developed from the traditional superficial radiotherapy unit. While retaining the core treatment functions, it significantly reduces the size and weight of the equipment and is equipped with a convenient mobility device, allowing it to be flexibly moved to different treatment scenarios. The equipment not only continues the precise radiotherapy characteristics of traditional superficial radiotherapy units, but also breaks through the site limitations of fixed radiotherapy equipment. It is especially suitable for scenarios requiring multi-site treatment, emergency treatment, or primary healthcare institutions, providing patients with a more convenient and efficient treatment option.

[0004] Existing superficial radiotherapy equipment has some obvious limitations in clinical applications. Although traditional fixed large superficial radiotherapy instruments can achieve high-precision dose output and irradiation positioning through precise mechanical structures and complex control systems, thereby avoiding problems such as damage to normal tissues or poor treatment effects caused by uneven dose distribution, their core components adopt a split design and need to be connected to fixed power supply and cooling systems, making the overall equipment bulky and heavy. It cannot be moved according to the patient's treatment needs, making it difficult to provide timely and effective diagnosis and treatment services for patients with limited mobility or in scenarios requiring emergency treatment at the bedside.

The rollers 2113 are rotatably connected inside the multiple brackets 2112, and the rotation of the rollers 2113 enables the device to move.

[0038] Specifically, the device cabinet 1 serves as the basic load-bearing structure of the equipment. The radiotherapy mechanism 2 at its top is the core of the radiotherapy function. The inner support mechanism 3 provides stable support for the radiotherapy mechanism 2, ensuring its structural stability during operation. The horizontal plate 201 is fixedly connected to its interior on all four sides, providing an installation platform for the power supply equipment 202 at the top. The power supply equipment 202 provides power support for the entire radiotherapy mechanism 2, ensuring the normal operation of each component.

[0039] Reference Figure 3 and Figure 5The support mechanism 3 includes a fixed column 301, which provides an upper connection point for the support structure. The top of the fixed column 301 is fixedly connected to the bottom of the connecting rod 205, achieving a stable connection between the fixed column 301 and the connecting rod 205. Rotating shafts 302 are fixedly connected to the left and right sides of the bottom of the fixed column 301, providing rotation fulcrums for the connecting column 303. Connecting columns 303 are rotatably connected to the far ends of the two rotating shafts 302, allowing the connecting columns 303 to rotate around the rotating shafts 302. Telescopic columns 304 are slidably connected to the bottom ends of the two connecting columns 303, allowing the telescopic columns 304 to slide within the connecting columns 303 to adjust their length. One side of the bottom of the device 4 is rotatably connected to a second rotating shaft 305. The second rotating shaft 305 provides a connection point between the telescopic column 304 and the fixed block 306. The second robotic arm 206 and the first robotic arm 204 are both fixedly connected to a fixed block 306. The fixed block 306 provides an installation position for the second rotating shaft 305. The two rotating shafts 305 are respectively fixedly connected to one side of the corresponding fixed block 306. The second rotating shaft 305 fixes the telescopic column 304 and the fixed block 306. The top right side of the device cabinet 1 is provided with a display component 307. The display component 307 is used to display radiotherapy related information. The rear side of the device cabinet 1 is provided with a pushing component 308. The pushing component 308 facilitates the movement of the device.

[0040] The display component 307 includes a support frame 3071, which provides support for the display 3072. The bottom of the support frame 3071 is fixedly connected to the top right side of the device cabinet 1, thus fixing the support frame 3071 to the device cabinet 1. The display 3072 is fixedly connected to the top front end of the support frame 3071, and the display 3072 can display positioning and dosage data.

[0041] The pushing component 308 includes two connecting blocks 3081. The connecting blocks 3081 are used to connect the device cabinet 1 and the pushing rod 3082.

The pushing rod 3082 provides a force application point for pushing the device.

[0042] Specifically, the support mechanism 3 effectively enhances the structural stability of the radiotherapy mechanism 2. The top of the fixed column 301 is fixed to the bottom of the connecting rod 205, providing an upper connection point for the support structure. The rotating shafts 302 on the left and right sides of its bottom allow the connecting column 303 to rotate flexibly, adapting to changes in the robotic arm's angle. The connecting column 303 is slidably connected to the telescopic column 304, allowing for length adjustment based on the robotic arm's position. The rotating shaft 305 on one side of the bottom of the telescopic column 304 is fixedly connected to the robotic arm 206 and the fixed block 306 adjacent to the robotic arm 204, forming a stable triangular support structure that can counteract the gravitational torque of the radiotherapy unit 207 and prevent deformation of the robotic arm. The display component 307 on the top right side of the device cabinet 1 is used to visualize the operation. The support frame 30... The bottom of component 71 is fixed to the top right side of the device cabinet 1, providing a stable mounting support for the display 3072. The display 3072 at the top front can display the coordinates of the positioning laser 2102, the angle parameters of the radiotherapy device 207, and the radiation dose in real time, which is convenient for operators to monitor and adjust. The push component 308 on the rear side of the device cabinet 1 facilitates the movement of the equipment. The two connecting blocks 3081 are fixed to the left and right ends of the rear side of the device cabinet 1, and the push rod 3082 is stably installed on the device cabinet 1. The push rod 3082 provides a force point for the operator. With the support 2112 and rollers 2113 of the moving component 211, the movement direction and speed of the equipment can be easily controlled, so that the equipment can be flexibly transported in the treatment environment to meet the needs of different treatment scenarios.

[0043] Reference Figure 4 The size of the card block 2094 matches that of the card slot 2092. The card block 2094 can be precisely embedded in the card slot 2092 to achieve a stable connection. The rear side of the base plate 2093 fits against the front side of the mounting plate 2091. There is no gap between the base plate 2093 and the mounting plate 2091, which can enhance the tightness of the connection.

[0044] Specifically, the size of the card block 2094 and the card slot 2092 are matched, enabling precise sliding engagement between them. This ensures that the collimator 208 will not loosen or wobble when connected to the mounting plate 2091 via the base plate 2093, thus guaranteeing the relative stability between the collimator 208 and the radiotherapy unit 207. This prevents the radiation beam from shifting due to connection gaps, thereby improving the accuracy of radiotherapy.

[0045] Working principle: The movable component 211 at the bottom of the device cabinet 1 provides basic mobility for the equipment. The base 2111 is connected to rollers 2113 via brackets 2112 at the four corners. The rotational cooperation between the brackets 2112 and the rollers 2113 allows the equipment to be moved within the treatment environment. Once at the designated position, locking the rollers 2113 achieves stable parking, laying the foundation for subsequent radiotherapy operations. The horizontal plate 201 at the top of the device cabinet 1 serves as the load-bearing base, and the power supply device 202 at its top provides power to the entire radiotherapy unit 2. The mounting base 203 is fixed to the rear top of the device cabinet 1. Through a rotatable connection with robotic arm 204, robotic arm 204 can rotate around the mounting base 203 at multiple angles. The front top of robotic arm 204 is connected to connecting rod 205 via a rotating shaft. The front end of connecting rod 205 is then rotatably connected to robotic arm 206, forming a multi-joint linkage structure. By adjusting the relative angles of robotic arm 204, connecting rod 205, and robotic arm 206, the operator can move the radiotherapy device 207 at the bottom to the corresponding superficial lesion of the patient. Positioning and support mechanism 3 provide stable support for the cantilever structure of radiotherapy mechanism 2 during this process, preventing positional displacement due to gravity. The mounting component 209 on the front side of radiotherapy unit 207 enables rapid assembly of the constrictor 208. The mounting plate 2091 is fixed to the front side of radiotherapy unit 207, and its multiple slots 2092 form a sliding engagement structure with the locking block 2094 on the rear side of base plate 2093, ensuring the coaxiality of constrictor 208 and radiotherapy unit 207. The circular grooves 2101 on the left and right ends of the front side of base plate 2093 are slidably connected to the fixed... Positioning laser 2102, by adjusting the position of positioning laser 2102 within circular groove 2101, causes its emitted laser beam to form a cross-shaped positioning mark on the patient's body surface. After aligning with the lesion location, the final irradiation angle of radiotherapy device 207 is confirmed. Power supply device 202 delivers energy to radiotherapy device 207. The radiation generated by radiotherapy device 207 is filtered and shaped by beam limiter 208 to form a precise beam conforming to the shape of the lesion. Beam limiter 208 limits the irradiation range of radiation by adjusting the internal lead plate assembly to avoid damage to healthy tissue.

[0046] Furthermore, when the robotic arm 1 204, connecting rod 205, and robotic arm 206 adjust their angles, the top of the fixed column 301 is rigidly connected to the connecting rod 205, and the bottom end drives the connecting columns 303 on both sides to rotate through the rotating shaft 1 302. The sliding fit between the connecting column 303 and the telescopic column 304 can adapt to changes in length. The bottom end of the telescopic column 304 is connected to the fixed block 306 through the rotating shaft 2 305. The fixed block 306 is fixed to the inner side of robotic arm 1 204 and robotic arm 206 respectively, forming a triangular stable support structure to counteract the gravitational torque of the radiotherapy device 207 and prevent the deformation of the robotic arm from affecting the positioning accuracy. The support frame 3071 holds the display 3072. Fixed to the top right of the device cabinet 1, the crosshair coordinates of the positioning laser 2102, the angle parameters of the radiotherapy unit 207, and the radiation dose are displayed in real time. By observing the data on the display 3072, the operator can fine-tune the angle of the robotic arm and the position of the positioning laser 2102 in the circular groove 2101 to ensure that the lesion and the irradiation area are completely overlapped. During the radiotherapy implementation phase, the support mechanism 3 maintains rigid support, and the collimator 208 is stably assembled with the mounting component 209 through the slot 2092 and the block 2094. Under the dose monitoring of the display 3072, the radiation emitted by the radiotherapy unit 207 is shaped by the collimator 208 and then acts on the treatment site.
