Description

Technical Field

[0001] The present invention relates to a device and a use method, in particular to a three-dimensional modeling device based on DSA images and a use method, belonging to the technical field of DSA image three-dimensional modeling. Background Art

[0002] DSA image 3D modeling equipment is mainly based on DSA imaging principles and 3D reconstruction technology. The DSA imaging principle is to obtain a clear image of the vascular structure by digitally processing two consecutive X-ray images. The 3D reconstruction technology uses these two-dimensional DSA images to generate a 3D model of tissue structures such as blood vessels through calculation and processing. By generating a 3D model of the blood vessels, doctors can clearly see the morphology, direction and pathological conditions of the blood vessels, so as to make an accurate diagnosis. Before interventional surgery, doctors can use the generated 3D model to plan the surgery, determine the surgical path, the selection of surgical instruments, etc., to improve the success rate and safety of the surgery.

[0003] The hardware structure of the 3D modeling equipment based on DSA images is relatively complex, but it can be mainly summarized into two types: DSA imaging system and 3D modeling related hardware. The DSA imaging system is composed of X-ray high-voltage generator, X-ray tube, detector, C-arm and other structures, and the 3D modeling related hardware is composed of rotating platform, driving mechanism and image processing equipment and other structures.

[0004] In existing DSA 3D modeling equipment, the X-ray high voltage generator and the detector are installed on the C-arm, but the distance between the X-ray high voltage generator and the detector cannot be adjusted, and thus the distance between the two cannot be adjusted according to usage requirements, resulting in a fixed imaging field of view. When it is necessary to shoot blood vessels or tissue structures of different sizes, the best imaging effect cannot be obtained;

[0005] The existing 3D modeling equipment does not have a special structure to protect the display. The display is easily damaged by bumps when the equipment is carried and transported. It is also inconvenient to protect and clean the display after use, which makes the display easily contaminated by dust, etc., affecting the display effect and the life of the equipment.

The inner walls of the heat dissipation grooves 227 are fixedly connected with cooling fans 228, and the heat inside the chassis 215 is discharged by the cooling fans 228, thereby dissipating the heat of the equipment inside the chassis 215; the lower parts of both sides of the lifting plate 214 are fixedly connected with limiting sliders 229, and the front parts of the adjacent sides of the two limiting plates 216 are provided with limiting slide grooves 230, and the outer wall of the limiting slider 229 is slidably connected to the inner wall of the limiting slide groove 230, and the limiting slider 229 on the lifting plate 214 slides inside the limiting slide groove 230, thereby limiting the limiting slider 229, thereby increasing the stability of the movement of the lifting plate 214.

[0084] In the second embodiment, specifically: both sides of the rear surface of the lifting plate 214 are fixedly connected to the limiting seat 231, and the outer wall of the rotating shaft 218 is rotatably connected to the inner wall of the limiting seat 231 on the side close to the gear 219, and the limiting seat 231 limits the rotating shaft 218, thereby increasing the stability of the rotation of the rotating shaft 218; the middle parts of both sides of the cover plate 223 are fixedly connected to the limiting strips 232, and the middle parts of both sides of the inner wall of the limiting groove 210 are provided with strip grooves 233, and the outer wall of the limiting strip 232 is slidably connected to the inner wall of the strip groove 233, and the limiting strip 232 on the cover plate 223 slides inside the strip groove 233, thereby limiting the limiting strip 232, thereby increasing the sliding stability of the cover plate 223.

[0085] In the second embodiment, specifically: a support frame 234 is fixedly connected to the outer side of the lower surface of the operating table 211, a reinforcement plate 235 is fixedly connected to the rear part of the inner wall of the support frame 234, the lower surface of the chassis 215 is fixedly connected to the middle part of the upper surface of the reinforcement plate 235, and the chassis 215 is reinforced by the reinforcement plate 235, thereby increasing the firmness of the chassis 215; a push-pull groove 236 is opened on the front part of the upper surface of the cover plate 223, and the push-pull groove 236 facilitates pushing the cover plate 223 to move.

[0086] When the present invention is working: when the device is not started, the display body 213 is located in the chassis 215, and the cover plate 223 is magnetically connected to the magnetic sheet 225 in the limiting groove 210 through the magnetic block 224, so as to cover the display body 213, play a protective role, and facilitate the movement and transportation of the device. When the device is started to perform three-dimensional modeling, first, the cover plate 223 is pulled through the push-pull groove 236 to open the cover plate 223, and then the bidirectional synchronous motor 217 is started to drive the rotating shaft 218 to rotate, so that the gear 219 on the outer wall of the rotating shaft 218 rotates, and the gear 219 is meshed with the tooth plate 221 in the limiting groove 220 at the rear of the limiting plate 216. With the rotation of the gear 219, the lifting plate 214 connected thereto is driven to rise, and the limiting sliding blocks 229 on both sides of the lifting plate 214 slide in the limiting slide groove 230 of the limiting plate 216 to ensure that the lifting plate 214 rises vertically and stably. During the rising process of the lifting plate 214, it drives the lifting plate 214 fixedly connected thereto to rise. The display body 213 slides upward in the through slot 212, gradually exposing the display body 213. While the display body 213 moves upward, the cleaning cotton 222 cleans the screen of the display body 213. During the operation of the equipment, heat may be generated in the chassis 215. At this time, the cooling fans 228 at the rear of both sides of the chassis 215 are started to dissipate heat through the heat dissipation slots 227 to keep the temperature in the chassis 215 within a suitable range to ensure the normal operation of the equipment. When the work is completed and the equipment needs to be turned off, the bidirectional synchronous motor 217 reverses to drive the rotating shaft 218 and the gear 219 to rotate in the opposite direction, so that the lifting plate 214 descends, and the lifting plate 214 drives the display body 213 to descend back to the initial position. At the same time, the cleaning cotton 222 cleans the screen of the display body 213 again. Finally, the cover plate 223 is pushed back to make the magnetic block 224 fit the magnetic sheet 225, and the display body 213 is protected again to prevent dust pollution.

Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
