Description

Technical Field

[0001] The present invention relates to the technical field of imaging diagnosis equipment, and in particular to a CT imaging diagnosis auxiliary manipulator. Background Art

[0002] The CT image diagnosis auxiliary manipulator is an intelligent service-type artificial intelligence robot that can provide important assistance in the CT image diagnosis process. Through high-precision positioning and flexible manipulation, this manipulator can help doctors obtain clearer CT images, reduce arm artifacts, and improve the accuracy of diagnosis.

[0003] The patent with application number CN202120769901.2 discloses a radiation protection device for a medical CT room, including a bed, a support column connected to one side of the bed, a support plate fixedly connected to the end of the support column away from the bed, a head support device is provided on the bed, and the head support device includes a placement table, a first placement slot is provided on the placement table, and a first slider is connected to the side of the placement table close to the bed. The problem that the existing CT medical equipment requires the patient to lie flat on the set bed when examining the patient, and the patient's head and feet are not supported, making the patient feel uncomfortable during the examination.

[0004] During chest and abdominal CT scans, if the patient can keep his arms raised vertically, the interference of arm tissue on the scanned image can be significantly reduced, thereby improving the clarity of the image and the accuracy of the diagnosis. However, some patients are unable to raise their arms vertically due to limited limb mobility. At this time, the patient's family members need to wear lead protective clothing to enter the examination room to assist the patient in adjusting the arm posture. Although the introduction of artificial intelligence robots to replace family members to assist in the operation is considered, this will not only increase the additional economic burden, but the size of the robot may also occupy the limited examination room space, adding inconvenience to the patient's transportation process. In addition, for patients with poor consciousness, family members need to closely monitor during the examination to prevent the patient from falling from the examination bed and ensure the safety of the examination process.

[0005] In view of this, we propose a CT image diagnosis auxiliary manipulator. Summary of the invention

DETAILED DESCRIPTION

[0039] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in 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 in 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.

[0040] See also Figure 1-Figure 11 As shown, this embodiment provides a technical solution:

[0041] A CT imaging diagnosis auxiliary manipulator comprises an examination bed 100, a protection device 200 arranged below the examination bed 100, two sets of parallel lifting devices 300, and a bed moving platform 400 for ensuring the structural stability of the examination bed 100;

[0042] The bed moving platform 400 is composed of a lifting barrel and a placement platform on the top of the lifting barrel. A transmission system for horizontally moving the entire examination bed 100 is arranged inside the placement platform. This system usually includes key components such as a motor, a reducer, a drive shaft, a guide rail, and a slider. When the operator issues a command to move the examination bed 100 through an external console, the control system activates the motor. After the motor is started, the high-speed and low-torque motor output is converted into low-speed and high-torque power through the reducer. This power is then transmitted through the drive shaft. The lead screw connecting the drive shaft to the examination bed 100 converts the rotational motion into linear motion, thereby driving the examination bed 100 to slide on the guide rail of the placement platform.

[0043] In the present invention, the examination bed 100 includes a fixed bed plate 110 fixedly connected to the bottom surface of the fixed bed plate 110 by bolts and having a concave longitudinal cross-section. The examination bed 100 also includes a headrest 130 placed on the top surface of the front end of the fixed bed plate 110 and a handle 140 fixedly connected to the top surface of the rear end of the fixed bed plate 110 by screws.

[0044] Specifically, bed board through grooves 111 that pass through from top to bottom are provided on the top surfaces at the left and right ends of the fixed bed board 110, a placement groove 112 for providing a placement space for the internal structure of the protective device 200 is provided on the bottom surface of the fixed bed board 110, and four regularly distributed and vertically extending limiting sliding grooves 113 are provided on the top surface of the fixed bed board 110.

[0045] Furthermore, the fixed bed board 110 is fixed above the top guide rail of the placement platform on the top of the bed moving platform 400, and the bottom is also threadedly connected to the screw in the transmission system of the bed moving platform 400. When the lifting bucket under the placement platform of the bed moving platform 400 is started, the height of the fixed bed board 110 will be driven to change. The bed board groove 111 is used to provide a placement interval for the lifting device 300, the limiting slide groove 113 is used to limit the moving range of the internal structure of the protective device 200, and the fixed bracket 120 is used to provide a rotating platform for the internal structure of the protective device 200.

[0046] In this embodiment, Figure 6-Figure 8 As shown, the protection device 200 includes a driving motor 210, a first screw rod 220 disposed on the output shaft of the driving motor 210, a moving horizontal plate 230 that moves as the first screw rod 220 rotates, a docking gear 260 that rotates as the moving horizontal plate 230 moves, and an upper lifting portion 290 that moves as the first screw rod 220 rotates;

[0047] Specifically, the driving motor 210 is fixedly connected to the inner groove wall of the placement groove 112 by bolts, the first screw rod 220 is coaxially connected to the output shaft of the driving motor 210, the movable cross plate 230 is slidably connected to the bottom surface of the fixed bed board 110 and is threadedly connected to the first screw rod 220, and fixed tooth plates 240 are welded and fixed on the top surfaces of the left and right ends of the movable cross plate 230. A rotating shaft 250 is provided above the movable cross plate 230 near the front end position, and the rotating shaft 250 is rotatably connected to the bottom of the fixed bed board 110. The docking gear 260 is fixedly connected to the end position of the rotating shaft 250 by a bayonet and meshes with the fixed tooth plate 240.

[0048] Furthermore, a worm 270 is sleeved on the outer wall of the first screw rod 220 near one end of the driving motor 210, and a second screw rod 280 is provided at one end of the worm rod 270. One end of the second screw rod 280 is rotatably connected to the bottom surface of the fixed bed board 110, and the other end is rotatably connected to the top surface of the bottom horizontal plate of the fixed bracket 120. A rod body gear 281 meshing with the worm 270 is welded and fixed on the outer wall of the second screw rod 280.

[0049] Furthermore, after the driving motor 210 is started, it drives the first screw rod 220 to rotate, and the movable cross plate 230 is displaced forward. The two ends of the movable cross plate 230 are slidably connected to the inside of the slide groove opened on the bottom surface of the fixed bed board 110. At this time, the fixed tooth plates 240 at the two ends of the top surface of the movable cross plate 230 contact the docking gear 260, and drive it to rotate. When the first screw rod 220 rotates, the worm 270 rotates therewith, and after contacting the rod body gear 281, it drives the second screw rod 280 to rotate.

[0050] In this embodiment, Fig. 9 As shown, the lifting portion 290 includes a lifting plate 291 and a protective baffle 292 disposed at the corner of the top surface of the lifting plate 291;

[0051] Specifically, the transverse cross-section of the lifting plate 291 is I-shaped and a number of regularly distributed weight-reducing grooves 2910 are provided on the top surfaces of the transverse plates at the front and rear ends. The center position of the lifting plate 291 is threadedly connected to the second screw rod 280, and the protective baffle 292 is fixedly connected to the top surface of the lifting plate 291 by bolts. The protective baffle 292 is slidably connected to the inside of the limiting slide groove 113.

[0052] Furthermore, after the second screw rod 280 rotates, the lifting plate 291 moves upward as a whole, thereby allowing the four sets of protective baffles 292 to extend above the fixed bed board 110. When the protective baffles 292 rise to the maximum height, the horizontal height of their top surfaces is higher than the horizontal height of the patient's abdomen. The weight-reducing grooves 2910 on the lifting plate 291 are used to reduce the overall weight of the lifting plate 291.

[0053] In this embodiment, Fig.10 As shown, the lifting device 300 includes an upwardly-turned horizontal plate 310 that rotates as the docking gear 260 rotates, a plurality of pressure springs 330 disposed inside the upwardly-turned horizontal plate 310, a limit rod 340 for limiting the rotation range of the upwardly-turned horizontal plate 310, and a clamping portion 360 disposed on the top surface of the upwardly-turned horizontal plate 310 for fixing the patient's wrist, and the lifting device 300 also includes a connecting rope 350 with one end connected to the limit rod 340 and the other end connected to the clamping portion 360;

[0054] Specifically, the size of the upper horizontal plate 310 is matched with the size of the bed board slot 111. The upper horizontal plate 310 is rotatably connected to the inside of the bed board slot 111 through the outer protruding rod at the front end. The end of the outer protruding rod of the upper horizontal plate 310 extends to the top of the docking gear 260 and its outer side wall is fixedly connected with the plate rod end tooth 320 meshing with the docking gear 260 by a bayonet pin. The top surface of the upper horizontal plate 310 is provided with a plate surface slot 311 with an inverted T-shaped longitudinal cross section.

[0055] Furthermore, one end of the pressure spring 330 is connected to the inner groove wall of the board groove 311, and the other end is connected to the outer wall of the inner slide plate 361. The elastic force provided by the pressure spring 330 is used to push the inner slide plate 361 to move toward the direction of the board rod end tooth 320. During actual use, a limiting telescopic rod is installed inside the pressure spring 330 to prevent the pressure spring 330 from shifting during the compression process. The limiting rod 340 is clamped and fixed to the inside of the bed board groove 111.

[0056] Furthermore, when the docking gear 260 rotates, the plate rod end teeth 320 meshing therewith rotate simultaneously, thereby driving the upward-turning horizontal plate 310 to turn upward as a whole and move to an angle of 150° with the top surface of the fixed bed board 110. At this time, the two ends of the movable horizontal plate 230 just move to the front end groove wall of the bottom groove of the fixed bed board 110. As the inclination angle of the upward-turning horizontal plate 310 continues to increase, the connecting rope 350 pulls the inner slide plate 361 to move inside the groove 311 of the plate surface, so that the patient's arms can always remain straight as the upward-turning horizontal plate 310 is lifted.

[0057] In this embodiment, Fig.11 As shown, the clamping portion 360 includes an inner plate slide 361, a wrist placement plate 362 disposed on the top surface of the inner plate slide 361, two sets of symmetrically disposed rubber clamps 364, and an upward spring 365 disposed on the outer side of the rubber clamps 364;

[0058] Specifically, the inner-board slide plate 361 is slidably connected to the inside of the board slot 311, and the wrist rest plate 362 is fixedly connected to the top surface of the inner-board slide plate 361 by screws. The top surface of the wrist rest plate 362 is adhered with a sponge pad to ensure surface comfort.

[0059] Furthermore, two parallel plate supports 363 are fixed on the outer walls of the left and right ends of the wrist placement plate 362 by welding, the rubber splint 364 is rotatably connected between the two plate supports 363 on the same side, and the front and rear ends of the upward spring 365 are welded and fixed to the plate supports 363 on both sides. The elastic force provided by the upward spring 365 is used to keep the plate support 363 in a vertical state as a whole.

[0060] Furthermore, the inner slide plate 361 is used to provide a placement platform for the wrist placement plate 362, and the plate body bracket 363 is used to provide a placement area for the rubber splint 364 and the upward spring 365. The rubber splint 364 is rotatably connected to the inside of the plate body bracket 363 to clamp and fix the patient's wrist.

[0061] Finally, it should be noted that the drive motor 210 and the bed moving platform 400 involved in the present invention are universal standard parts or parts known to technical personnel in this field, and their structures and principles can be known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle space of this device, the drive motor 210 and the motor of the internal transmission system of the bed moving platform 400 are connected to the external power supply through a wire. The specific connection method should refer to the working principle of the present invention. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection methods are all well-known technologies in the field.

[0062] When the CT imaging diagnosis auxiliary manipulator of the present invention is used, the patient is first pushed into the examination room, and the lifting bucket under the bed moving platform 400 is controlled to adjust the height of the fixed bed board 110. After the patient is placed on the fixed bed board 110, the patient's head is ensured to be rested on the headrest 130, and the rubber splint 364 is pulled outward to place the patient's wrists on both sides of the wrist placement plates 362 of the clamping parts 360 on both sides respectively;

[0063] Next, the driving motor 210 is started to drive the first screw rod 220 to rotate, and the movable horizontal plate 230 is displaced forward. At this time, the fixed tooth plates 240 at both ends of the top surface of the movable horizontal plate 230 come into contact with the docking gear 260, and drive it to rotate;

[0064] Then, when the docking gear 260 rotates, the plate rod end teeth 320 meshing therewith rotate simultaneously, driving the upward flipping horizontal plate 310 to flip upward as a whole, and move to an angle of 150° with the top surface of the fixed bed plate 110. As the tilt angle of the upward flipping horizontal plate 310 increases, the connecting rope 350 pulls the inner plate slide 361 to move inside the plate surface slot 311, so that the patient's arms are always kept in a straight state as the upward flipping horizontal plate 310 is lifted.

[0065] When the first screw rod 220 rotates, the worm 270 rotates together with it, and after contacting the rod body gear 281, it drives the second screw rod 280 to rotate, so that the lifting plate 291 moves upward as a whole, and then the four sets of protective baffles 292 extend to the top of the fixed bed board 110, forming guardrails on both sides of the patient's body;

[0066] Afterwards, the motor inside the transmission system of the bed moving platform 400 is started, and the mobile examination bed 100 as a whole moves linearly along the table guide rail of the bed moving platform 400 to send the patient into the interior of the front-end CT machine;

[0067] When the patient finishes the CT examination, the motor inside the bed moving platform 400 is first controlled to move the mobile examination bed 100 out of the CT machine, and then the drive motor 210 is controlled to rotate in the reverse direction to restore the internal structure of the protective device 200 and the lifting device 300 to the initial state.

[0068] The foregoing description of specific exemplary embodiments of the present invention is for the purpose of illustration and demonstration. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings. The purpose of selecting and describing exemplary embodiments is to explain the specific principles of the present invention and its practical application, so that those skilled in the art can realize and utilize various different exemplary embodiments of the present invention and various different selections and changes. The scope of the present invention is intended to be limited by the specification and its equivalents.
