Description

Technical Field

[0001] This invention relates to the field of ultrasound positioning equipment technology, specifically to an ultrasound-guided tumor positioning device and method. Background Technology

[0002] Ultrasound-guided minimally invasive tumor treatment is a novel treatment method that combines ultrasound imaging technology with minimally invasive techniques. This type of treatment includes radiofrequency ablation (RFA), microwave ablation (MWA), high-intensity focused ultrasound (HIFU), and cryoablation. The clinical application of ultrasound-guided minimally invasive tumor treatment is already widespread, and its main application areas currently include: liver tumors, kidney tumors, thyroid nodules, breast tumors, and soft tissue tumors.

[0003] In existing technologies, before performing ultrasound examinations on patients, they need to lie on the examination bed and straighten their bodies for more accurate examinations. However, for some patients with limited mobility, it is difficult to straighten their bodies when lying on the examination bed, which requires the assistance of medical staff, thus reducing the efficiency of ultrasound examinations. Summary of the Invention

[0004] The purpose of this invention is to provide an ultrasound-guided tumor localization device and method to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to an ultrasound-guided tumor localization device and method, comprising a detection bed, a motor fixedly connected to the bottom of the detection bed, a screw fixedly connected to the output end of the motor, support frames fixedly connected to both sides of the detection bed, a guide rail fixedly connected to the top of the inner wall of the support frame, a motor fixedly connected to the surface of the guide rail, and a threaded screw fixedly connected to the output end of the motor; characterized in that it further comprises; A corrective mechanism, comprising a corrective plate, wherein a support telescopic rod is fixedly connected to the end of the corrective plate; The testing mechanism includes a support frame, a force spring is fixedly connected to the inner wall of the support frame, and an ultrasonic testing ring is fixedly connected to the end of the force spring away from the support frame. A positioning mechanism, the positioning mechanism including a clamping plate, wherein a force-bearing plate is fixedly connected to the surface of the clamping plate; Furthermore, the surface of the testing bed is provided with sliding groove holes, the end of the screw away from the motor is rotatably connected to the top of the testing bed, and there are two support frames, both of which are located on both sides of the testing bed.

[0006] Furthermore, the correction mechanism includes a threaded ring, a pull-down bracket is fixedly connected to the surface of the threaded ring, a push rod is rotatably connected to the end of the pull-down bracket away from the threaded ring, a slide rod is fixedly connected to the inner wall of the slide groove hole, and a movable bed board is slidably connected to the surface of the slide rod.

[0007] Furthermore, the inner wall of the threaded ring is threadedly connected to the surface of the screw, the end of the support telescopic rod away from the support telescopic rod is fixedly connected to both sides of the inner wall of the support frame, the end of the push rod away from the pull-down bracket is rotatably connected to the surface of the straightening plate, and two straightening plates are provided, with a moving groove on the surface of the straightening plate.

[0008] Furthermore, the detection mechanism includes a movable slide plate, a slide frame is slidably connected to the surface of the movable slide plate, a driven push plate is fixedly connected to the bottom of the slide frame, and a lower push rod is rotatably connected to the surface of the slide frame.

[0009] Furthermore, the inner wall of the movable slide plate is threadedly connected to the surface of the threaded screw, the two sides of the movable slide plate are slidably connected to the surface of the guide rail, the end of the driven push plate away from the slide frame is slidably connected to the inner wall of the movable groove, the end of the lower push rod away from the slide frame is rotatably connected to the surface of the support frame, and a sliding groove is provided on the top of the support frame.

[0010] Furthermore, the positioning mechanism includes a driven telescopic plate, an elastic plate is fixedly connected to the surface of the driven telescopic plate, a pressing rod is fixedly connected to both ends of the elastic plate, a sliding groove plate is fixedly connected to the surface of the elastic plate, and a limiting elastic rod is fixedly connected to the lower surface of the clamping plate.

[0011] Furthermore, the end of the extrusion rod away from the elastic plate contacts the surface of the force plate, the bottom of the clamping plate is slidably connected to the inner wall of the slide plate, the end of the driven telescopic plate is fixedly connected to the surface of the driven push plate, and the end of the driven telescopic plate away from the driven push plate is slidably connected to the inner wall of the slide.

[0012] Furthermore, the method for using an ultrasound-guided tumor localization device includes the following steps: S1: When the patient moves, the movable bed board will slide on the surface of the slide bar toward the middle of the two correction boards, thereby avoiding friction between the patient and the surface of the movable bed board, allowing the patient to move quickly to the middle position; S2: When the patient is overweight, the ultrasonic detection ring will compress the force spring upward during the movement. At the same time, the ultrasonic detection ring will always be in contact with the patient's skin surface due to the elasticity of the force spring. This can effectively detect the patient's body shape, thereby improving its practicality. S3: When the clamping plate slides, it will clamp the surface of the support frame, thereby making the ultrasonic testing ring more stable during the testing process. When the clamping plate moves, it will push the limiting elastic rod to contract in the direction of mutual approach, so that the two clamping plates can be reset to their original positions according to the elasticity of the limiting elastic rod. S4: When the driven telescopic plate extends, it will drive the elastic plate to move downward as a whole, and move downward synchronously with the support frame, effectively positioning the entire support frame so that the ultrasonic testing ring is more stable and the testing is more accurate during the testing process.

[0013] The present invention has the following beneficial effects: This invention employs a correction mechanism. When the patient lies comfortably on the slide bar, a motor is activated, driving a screw to rotate. The rotation of the screw causes a threaded ring to move downwards, which in turn moves a pull-down bracket downwards. This pull-down bracket then pulls a push rod downwards, which in turn pushes the correction plates closer together, bringing them into contact with the patient's sides and propelling the patient towards the center. This movement of the patient causes a movable bed board to slide across the slide bar towards the center of the two correction plates, thus avoiding friction between the patient and the movable bed board surface and allowing the patient to quickly move to the center. The movement of the movable bed board also causes the supporting telescopic rod to extend closer together, achieving rapid patient correction, saving labor for medical staff, and improving testing efficiency.

[0014] This invention employs a detection mechanism. When the supporting telescopic rod moves, it simultaneously drives the driven push plate to move closer together. As the driven push plate moves, it pushes the slide carriage on the surface of the moving slide plate to slide closer together. When the slide carriage slides, it pushes the lower push rod to move closer together. When the lower push rod moves, it pushes the support frame downwards. When the support frame moves, it drives the force spring downwards. When the force spring moves downwards, it pushes the ultrasonic detection ring downwards and into contact with the patient's skin. At this point, the motor is activated, driving the threaded screw to rotate. When the threaded screw rotates, it causes the moving slide plate to move in the opposite direction to the motor. When the sliding plate moves, it drives the slide, driven push plate, and lower push rod to move in the opposite direction to the motor. When the lower push rod moves, it drives the support frame, force spring, and ultrasonic detection ring to move in the opposite direction to the motor, and causes the motor to move against the patient's skin. As the ultrasonic detection ring moves, it can detect the patient's body shape. When the patient is overweight, the ultrasonic detection ring will compress the force spring upwards during movement. At the same time, the ultrasonic detection ring will always be in contact with the patient's skin surface due to the elasticity of the force spring. This effectively detects the patient's body shape, thereby improving its practicality.

[0015] This invention employs a positioning mechanism. When the driven push plate moves, it pushes the driven telescopic plate towards each other. The movement of the telescopic plate further pushes the elastic plate towards each other, compressing it. When the elastic plate is compressed, its central portion bends. This bending pushes the sliding plate towards the support frame. The sliding plate's movement then pushes the clamping plate towards the support frame. The sliding plate's movement also causes the force-bearing plate to move towards the support frame. This force-bearing plate, under the pressure of the compression rod, moves towards each other. Finally, the force-bearing plate pushes the clamping plate to slide along the inner wall of the sliding plate towards each other. When the clamping plate slides, it clamps the surface of the support frame, making the ultrasonic testing ring more stable during the testing process. When the clamping plate moves, it pushes the limiting elastic rod to contract in the direction of mutual approach. Thus, according to the elasticity of the limiting elastic rod, the two clamping plates return to their original positions upon reset. When the driven telescopic plate moves, it slides in the direction of mutual approach on the inner wall of the slide groove. When the support frame moves downward, it pulls the driven telescopic plate downward. When the driven telescopic plate extends, it drives the elastic plate to move downward as a whole, moving downward synchronously with the support frame. This effectively positions the entire support frame, making the ultrasonic testing ring more stable and accurate during the testing process.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

An ultrasonic detection ring 37 is fixedly connected to the end of the force spring 36 away from the support frame 35. When the force spring 36 moves downward, it pushes the ultrasonic detection ring 37 to move downward and contact the patient's skin. The positioning mechanism 50 includes a clamping plate 55. When the clamping plate 55 slides, it clamps the surface of the support frame 35, thereby making the ultrasonic detection ring 37 more stable during the detection process. When the slide plate 54 moves, it pushes the clamping plate 55 to move towards the support frame 35. A force plate 56 is fixedly connected to the surface of the clamping plate 55. When the force plate 56 moves, it pushes the clamping plate 55 to slide towards each other on the inner wall of the slide plate 54. When the slide plate 54 moves, it drives the force plate 56 to move towards the support frame 35. The surface of the testing bed 1 is provided with a sliding groove hole. The end of the screw 3 away from the motor 2 is rotatably connected to the top of the testing bed 1. There are two support frames 4, and both support frames 4 are set on both sides of the testing bed 1.

[0022] The correction mechanism 10 includes a threaded ring 11. A starting motor 2 drives a screw 3 to rotate. When the screw 3 rotates, the threaded ring 11 moves downward. A pull-down bracket 12 is fixedly connected to the surface of the threaded ring 11. A push rod 13 is rotatably connected to the end of the pull-down bracket 12 away from the threaded ring 11. When the pull-down bracket 12 moves, it pulls the push rod 13 downward. A slide rod 16 is fixedly connected to the inner wall of the slide groove hole. When the patient lies on the surface of the slide rod 16 and is in a proper position, a movable bed board 17 is slidably connected to the surface of the slide rod 16, thereby achieving rapid correction of the patient, saving the labor of medical staff and improving the efficiency of testing.

[0023] The inner wall of the threaded ring 11 is threadedly connected to the surface of the screw 3. The end of the support telescopic rod 15 away from the support telescopic rod 15 is fixedly connected to both sides of the inner wall of the support frame 4. The end of the push rod 13 away from the pull-down frame 12 is rotatably connected to the surface of the correction plate 14. When the threaded ring 11 moves, it will drive the pull-down frame 12 to move downward. There are two correction plates 14. The surface of the correction plate 14 is provided with a moving groove. When the patient moves, it will drive the moving bed board 17 to slide on the surface of the slide rod 16 toward the middle of the two correction plates 14, thereby avoiding friction between the patient and the surface of the moving bed board 17, and allowing the patient to move quickly to the middle position.

[0024] The testing mechanism 30 includes a movable slide plate 31, with a slide frame 32 slidably connected to its surface. A driven push plate 33 is fixedly connected to the bottom of the slide frame 32. When the support telescopic rod 15 moves, it drives the driven push plate 33 to move closer to each other. A lower push rod 34 is rotatably connected to the surface of the slide frame 32. When the slide frame 32 slides, it pushes the lower push rod 34 to move closer to each other. When the lower push rod 34 moves, it drives the support frame 35, the force spring 36, and the ultrasonic detection ring 37 to move in the opposite direction to the motor 6, and causes the motor 6 to move on the patient's skin. During the movement of the ultrasonic detection ring 37, it can perform testing based on the patient's body size. When the patient is overweight, the ultrasonic detection ring 37 will compress the force spring 36 upwards during the movement. At the same time, the ultrasonic detection ring 37 will always adhere to the patient's skin surface due to the elasticity of the force spring 36, effectively allowing testing based on the patient's body shape, thereby improving practicality.

[0025] The inner wall of the movable slide plate 31 is threadedly connected to the surface of the threaded screw 7. When the driven push plate 33 moves, it pushes the slide 32 to slide closer to each other on the surface of the movable slide plate 31. At this time, the start motor 6 drives the threaded screw 7 to rotate. When the threaded screw 7 rotates, it causes the movable slide plate 31 to move in the opposite direction to the motor 6. The two sides of the movable slide plate 31 are slidably connected to the surface of the guide rail 5. The end of the driven push plate 33 away from the slide 32 is slidably connected to the inner wall of the movable groove. The end of the lower push rod 34 away from the slide 32 is rotatably connected to the surface of the support frame 35.

The top of the support frame 35 is provided with a sliding groove.

[0026] The positioning mechanism 50 includes a driven telescopic plate 51. When the support frame 35 moves downward, it pulls the driven telescopic plate 51 downward. Simultaneously, when the driven push plate 33 moves, it pushes the driven telescopic plate 51 towards each other. An elastic plate 52 is fixedly connected to the surface of the driven telescopic plate 51. When the driven telescopic plate 51 extends, it drives the elastic plate 52 to move downward as a whole, synchronously with the support frame 35. Compression rods 53 are fixedly connected to both ends of the elastic plate 52. When the force plate 56 moves, it moves towards each other through the compression of the compression rods 53. A sliding plate 54 is fixedly connected to the surface of the elastic plate 52. When the middle part of the elastic plate 52 bends, it will push the sliding plate 54 to move towards the support frame 35. A limiting elastic rod 57 is fixedly connected to the lower surface of the clamping plate 55. When the clamping plate 55 moves, it will push the limiting elastic rod 57 to contract towards each other. Thus, according to the elasticity of the limiting elastic rod 57, the two clamping plates 55 can be reset to their original positions during reset, effectively positioning the entire support frame 35, so that the ultrasonic detection ring 37 is more stable and the detection is more accurate during the detection process.

[0027] The end of the compression rod 53 away from the elastic plate 52 is in contact with the surface of the force plate 56. When the driven telescopic plate 51 moves, it pushes the elastic plate 52 to move closer to each other. When the driven telescopic plate 51 moves, it slides in the inner wall of the chute in the direction of closer to each other and compresses the elastic plate 52. When the elastic plate 52 is compressed, the middle part will bend. The bottom of the clamping plate 55 is slidably connected to the inner wall of the chute plate 54. The end of the driven telescopic plate 51 is fixedly connected to the surface of the driven push plate 33. The end of the driven telescopic plate 51 away from the driven push plate 33 is slidably connected to the inner wall of the chute.

[0028] A method for using an ultrasound-guided tumor localization device includes the following steps: S1: When the patient moves, the movable bed board 17 will slide on the surface of the slide bar 16 toward the middle of the two correction plates 14, thereby avoiding friction between the patient and the surface of the movable bed board 17, and allowing the patient to move quickly to the middle position. S2: When the patient is overweight, the ultrasonic detection ring 37 will press the force spring 36 upward during the movement. At the same time, the ultrasonic detection ring 37 will always be in contact with the patient's skin surface through the elasticity of the force spring 36. It can effectively detect according to the patient's body shape, thereby improving its practicality. S3: When the clamping plate 55 slides, it will clamp the surface of the support frame 35, thereby making the ultrasonic detection ring 37 more stable during the detection process. When the clamping plate 55 moves, it will push the limiting elastic rod 57 to contract in the direction of mutual approach, so that the two clamping plates 55 can be reset to their original positions according to the elasticity of the limiting elastic rod 57 during reset. S4: When the driven telescopic plate 51 extends, it will drive the elastic plate 52 to move downward as a whole, and move downward synchronously with the support frame 35, effectively positioning the support frame 35 as a whole, so that the ultrasonic detection ring 37 is more stable and the detection is more accurate during the detection process.

[0029] In use, when the patient lies on the surface of the slide bar 16 and is in a comfortable position, the motor 2 is started, driving the screw 3 to rotate. When the screw 3 rotates, the threaded ring 11 moves downwards. When the threaded ring 11 moves, it drives the pull-down bracket 12 downwards. When the pull-down bracket 12 moves, it pulls the push rod 13 downwards. When the push rod 13 moves, it pushes the corrective plates 14 towards each other, bringing them into contact with the patient's sides and pushing the patient towards the center. As the patient moves, the movable bed board 17 slides on the surface of the slide bar 16 towards the center of the two corrective plates 14, thus avoiding friction between the patient and the surface of the movable bed board 17, allowing the patient to quickly move to the center. When the movable bed board 17 moves, it drives the supporting telescopic rod 15 towards each other. Extending forward, as the supporting telescopic rod 15 moves, it drives the driven push plate 33 to move closer to each other. When the driven push plate 33 moves, it pushes the slide 32 to slide closer to each other on the surface of the moving slide plate 31. When the slide 32 slides, it pushes the lower push rod 34 to move closer to each other. When the lower push rod 34 moves, it pushes the supporting frame 35 to move downward. When the supporting frame 35 moves, it drives the force spring 36 to move downward. When the force spring 36 moves downward, it pushes the ultrasonic detection ring 37 to move downward and contact the patient's skin. At this time, the start motor 6 drives the threaded screw 7 to rotate. When the threaded screw 7 rotates, it causes the moving slide plate 31 to move in the opposite direction to the motor 6. When the moving slide plate 31 moves, it drives the slide 32 to move closer to each other. 2. The driven push plate 33 and the lower push rod 34 move in the opposite direction to the motor 6. When the lower push rod 34 moves, it drives the support frame 35, the force spring 36, and the ultrasonic detection ring 37 to move in the opposite direction to the motor 6, causing the motor 6 to move against the patient's skin. During the movement of the ultrasonic detection ring 37, it can perform detection based on the patient's body size. When the patient is overweight, the ultrasonic detection ring 37 will compress the force spring 36 upwards during the movement. At the same time, the ultrasonic detection ring 37 will always be in contact with the patient's skin surface due to the elasticity of the force spring 36. When the driven push plate 33 moves, it pushes the driven telescopic plate 51 to move closer to each other. When the driven telescopic plate 51 moves, it pushes the elastic plate 52 to move closer to each other. The ultrasonic testing ring 37 moves in the direction of compression and presses the elastic plate 52. When the elastic plate 52 is compressed, the middle part of the elastic plate 52 bends. When the middle part of the elastic plate 52 bends, it pushes the slide plate 54 towards the support frame 35. When the slide plate 54 moves, it pushes the clamping plate 55 towards the support frame 35. When the slide plate 54 moves, it drives the force plate 56 towards the support frame 35. When the force plate 56 moves, it moves towards each other due to the compression of the compression rod 53. When the force plate 56 moves, it pushes the clamping plate 55 to slide towards each other on the inner wall of the slide plate 54. When the clamping plate 55 slides, it clamps the surface of the support frame 35, thereby making the ultrasonic testing ring 37 more stable during the testing process.When the clamping plate 55 moves, it pushes the limiting elastic rod 57 to retract in a direction closer to each other. This allows the two clamping plates 55 to return to their original positions upon reset, based on the elasticity of the limiting elastic rod 57. Simultaneously, the driven telescopic plate 51 slides along the inner wall of the groove in a direction closer to each other. When the support frame 35 moves downward, it pulls the driven telescopic plate 51 downward. This downward extension of the driven telescopic plate 51 causes the elastic plate 52 to move downward as a whole, moving synchronously with the support frame 35.

The ultrasound-guided tumor localization device according to claim 7, characterized in that: The end of the extrusion rod (53) away from the elastic plate (52) is in contact with the surface of the force plate (56), the bottom of the clamping plate (55) is slidably connected to the inner wall of the slide plate (54), the end of the driven telescopic plate (51) is fixedly connected to the surface of the driven push plate (33), and the end of the driven telescopic plate (51) away from the driven push plate (33) is slidably connected to the inner wall of the slide.

9. A method for ultrasound-guided tumor localization according to claim 8, characterized in that, Includes the following steps: S1: When the patient moves, the moving bed board (17) will slide on the surface of the slide bar (16) toward the middle of the two correction boards (14), thereby avoiding friction between the patient and the surface of the moving bed board (17) and allowing the patient to move quickly to the middle position. S2: When the patient is overweight, the ultrasound detection ring (37) will press the force spring (36) upward during the movement. At the same time, the ultrasound detection ring (37) will always adhere to the patient's skin surface through the elastic force of the force spring (36), which can effectively detect the patient's body shape and thus improve its practicality. S3: When the clamping plate (55) slides, it will clamp the surface of the support frame (35), thereby making the ultrasonic detection ring (37) more stable during the detection process. When the clamping plate (55) moves, it will push the limiting elastic rod (57) to contract in the direction of mutual approach. Thus, according to the elasticity of the limiting elastic rod (57), the two clamping plates (55) can be reset to their original positions during the reset. S4: When the driven telescopic plate (51) extends, it will drive the elastic plate (52) to move downward as a whole, and move downward in sync with the support frame (35), effectively positioning the support frame (35) as a whole, so that the ultrasonic detection ring (37) is more stable during the detection process and the detection is more accurate.
