Description

Technical Field

[0001] This invention belongs to the field of medical technology, and in particular relates to a CT-assisted positioning mechanism with multi-angle adaptive adjustment. Background Technology

[0002] CT, or computed tomography, uses precisely collimated X-ray beams, gamma rays, ultrasound waves, etc., along with highly sensitive detectors, to scan a specific part of the human body one section after another. It features fast scanning time and clear images and can be used to examine a variety of diseases.

[0003] During the examination, the patient lies on the CT bed in a natural lying position. If the patient has a posture problem, due to the prolonged posture problem, the patient may not realize that they are not lying flat. The patient's body parts are not in the correct height position, which leads to inaccurate CT scan results. Afterwards, medical staff need to readjust and perform another CT scan. The increased number of CT scans has a significant impact on the patient and is detrimental to the patient's health. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-angle adaptive adjustment CT-assisted positioning mechanism, which aims to solve the technical problem in the prior art that it is not possible to quickly adjust the patient's position to correct inaccurate subsequent scanning results.

[0005] This invention is implemented as follows: a multi-angle adaptive adjustment CT-assisted positioning mechanism includes a bed, a headrest fixedly installed in the middle of the bed, a through groove on one side of the headrest on the bed, a support rod rotatably installed in the through groove, multiple sets of spaced support plates fixedly installed on the support rod, a cylinder rotatably connected to one end of the support plate, and the end of the cylinder away from the support plate rotatably connected to the bottom of the through groove, first connecting grooves on both ends of the support plate, a pad for positioning and restricting the patient's body position in the first connecting groove, a bracket fixedly installed on one side of the through groove on the bed, a movable plate slidably installed on the horizontal section of the bracket, and a servo module for driving the movable plate to move on the bracket, a detection probe fixedly installed on the movable plate.

[0006] Further technical solution: The cylinder is made of non-metallic material, and the cylinder is connected to an external air supply device through a pipeline.

[0007] A further technical solution: A support plate is slidably installed in the first connecting groove. A limiting groove is opened on the support plate in the first connecting groove. A movable frame is slidably installed on the support plate. The movable frame is frame-shaped and a pad is fixedly installed at one end of the movable frame. An adjusting screw that drives the movable frame to move is rotatably installed on the support plate.

[0008] Further technical solution: The first connecting groove is connected to a second connecting groove opened in the support plate. The first connecting groove is perpendicular to the second connecting groove. A limiting plate is slidably installed in the second connecting groove. A limiting airbag is fixedly installed on the surface of the limiting plate away from the first connecting groove. The end of the limiting airbag away from the limiting plate is connected to the side wall of the second connecting groove. When the limiting airbag is in its original state, the limiting plate extends into the limiting groove.

[0009] A further technical solution: The limiting plate has an inclined structure at one end located in the limiting groove, and a pressure plate that extends into the limiting groove and is used to push the limiting plate to move is slidably installed on the support plate.

[0010] A further technical solution: Both ends of the support plate are provided with mounting grooves, and a first support airbag for supporting the patient's body is fixedly installed in the mounting groove. The first support airbag includes an installation part and a support part that are interconnected. The installation part is located in the mounting groove and is fixedly connected to the support plate. The installation part is connected to a connecting pipe, and the connecting pipe is connected to an external air supply device.

[0011] A further technical solution: After the support is inflated, it is located outside the mounting groove. The support is distributed on both sides of the support plate. When there is no pressure on the support, the upper surface of the support is higher than the upper surface of the support plate.

[0012] A further technical solution: The surface of the support part that does not contact the patient is connected to multiple sets of second support airbags. The second support airbags are cylindrical, and the second support airbags are set at an angle to the surface of the support part.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The moving plate drives the detection probe to capture and scan the patient's body, thereby obtaining the patient's postural parameters when lying down. By rotating the support plate, the lower part of the patient's body is raised, thus putting the patient in a supine position. After detecting the patient's posture, the support plate adjusts the patient's height without requiring the patient to make adjustments themselves, ensuring that the patient's body is in a supine position. This avoids the patient's posture being uneven, which could affect subsequent scan results. At the same time, it can ensure the patient's posture is accurate before CT scan, reducing the patient's adjustment time, avoiding multiple CT scans, and reducing the impact of CT scans on the patient.

[0014] 2. When a significant tilt or even a side-lying position is required, multiple sets of pads are installed on the underside of the patient's body in the direction of rotation. Then, the multiple sets of support plates are rotated in one direction simultaneously, causing the patient's body to tilt and rotate until the set angle is reached. This enables rapid adjustment of the patient's position while ensuring the accuracy of the position, thereby improving the accuracy of subsequent CT scans.

[0015] 3. When the support plate rotates, the higher end of the support plate exceeds the plane formed by the other support plates. At this time, the first support airbag at the higher position of the support plate is inflated through the connecting pipe. After the first support airbag is inflated, it extends out of the mounting groove. The support part extends to both sides of the support plate and comes into contact with the patient's body after inflation. The support part provides auxiliary support to the patient's body, increases the support area for the patient, thereby reducing the pressure on the patient's body at the support position, avoiding pressure injury to the patient's body and improving the patient's comfort.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0025] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0026] like Figures 1-7 As shown, this invention provides a multi-angle adaptive adjustment CT-assisted positioning mechanism, including a bed 1, a headrest 3 fixedly installed in the middle of the bed 1, a through groove 2 on one side of the headrest 3 on the bed 1, a support rod 8 rotatably installed in the through groove 2, multiple sets of spaced support plates 9 fixedly installed on the support rod 8, a cylinder 10 rotatably connected to one end of the support plate 9, the cylinder 10 being made of non-metallic material, the cylinder 10 being connected to an external air supply device through a pipe, the end of the cylinder 10 away from the support plate 9 being rotatably connected to the bottom of the through groove 2, first connecting grooves 11 being provided at both ends of the support plate 9, a pad 20 for positioning and restricting the patient's body position provided in the first connecting groove 11, a bracket 4 fixedly installed on one side of the through groove 2 on the bed 1, a movable plate 5 slidably installed on the horizontal section of the bracket 4, and a servo module 6 for driving the movable plate 5 to move on the bracket 4, a detection probe 7 fixedly installed on the movable plate 5.

[0027] In practical application, the support rod 8 is initially horizontal, the patient lies on the bed 1 with their head on the headrest 3, and their upper body on the support plate 9. After the patient lies down, a pad 20 is installed at the end of the support plate 9 corresponding to the patient's shoulder, upper arm, and hip positions, and the pad 20 is made in contact with the patient's body. The servo module 6 drives the moving plate 5 to move, and the moving plate 5 drives the detection probe 7 to take pictures and scan the patient's body, thereby obtaining the patient's postural parameters after lying down, and then determining whether the patient's body is in a supine position. The detected patient postural parameters are compared with the postural parameters of a normal person. If the height of a certain part of the patient is too low, the cylinder 10 is extended or... The cylinder 10 rotates the corresponding support plate 9, raising the patient's lower body position and placing the patient in a supine position. The rotation of the support plate 9 generates a lateral thrust on the patient, which is maintained by the pad 20 to prevent lateral movement. After detecting the patient's posture, the support plate 9 adjusts the patient's height without requiring the patient to adjust themselves, ensuring the patient remains supine. This avoids the patient's posture affecting subsequent scan results, and ensures accurate patient posture before CT scan, reducing adjustment time and minimizing the impact of CT scans on the patient. When a significant tilt or even a side-lying position is required, multiple sets of pads 20 are installed on the underside of the patient's body in the direction of rotation. Then, multiple sets of support plates 9 are rotated in one direction simultaneously, causing the patient's body to tilt and rotate until the set angle is reached. This enables rapid adjustment of the patient's position and ensures the accuracy of the position, thereby improving the accuracy of subsequent CT scans.

[0028] like Figure 4 , Figure 7 As shown, a multi-angle adaptive adjustment CT auxiliary positioning mechanism provided by the present invention is provided. A support plate 13 is slidably installed in the first connecting groove 11. A limiting groove 14 located in the first connecting groove 11 is opened on the support plate 13. A movable frame 18 is slidably installed on the support plate 13. The movable frame 18 is frame-shaped and a pad 20 is fixedly installed on one end of the movable frame 18. An adjusting screw 19 that drives the movable frame 18 to move is rotatably installed on the support plate 13.

[0029] Specifically, the first connecting groove 11 is connected to the second connecting groove 12 opened in the support plate 9. The first connecting groove 11 and the second connecting groove 12 are perpendicular. A limiting plate 16 is slidably installed in the second connecting groove 12. A limiting airbag 15 is fixedly installed on the surface of the limiting plate 16 away from the first connecting groove 11. One end of the limiting airbag 15 away from the limiting plate 16 is connected to the side wall of the second connecting groove 12. When the limiting airbag 15 is in its original state, the limiting plate 16 extends into the limiting groove 14.

[0030] Specifically, the limiting plate 16 has an inclined structure at one end located in the limiting groove 14, and a pressure plate 17 extending into the limiting groove 14 is slidably installed on the support plate 13 for pushing the limiting plate 16 to move.

[0031] In practical application, the support plate 13 is inserted into the first connecting groove 11. When the support plate 13 moves downward, its lower end contacts the inclined surface of the limiting plate 16. The movement of the support plate 13 pushes the limiting plate 16 to move and squeezes the limiting airbag 15. After the support plate 13 moves to the bottom of the first connecting groove 11, the limiting plate 16 enters the limiting groove 14 under the action of the limiting airbag 15, thereby fixing the position of the support plate 13. Subsequently, the moving frame 18 is moved by adjusting the screw 19 so that the pad 20 contacts the patient's body. When not in use, press down on the pressure plate 17. The lower end of the pressure plate 17 contacts the inclined surface of the limiting plate 16. The pressure plate 17 pushes the limiting plate 16 to move and squeezes the limiting airbag 15, causing the limiting plate 16 to leave the limiting groove 14. Then the support plate 13 can be pulled out from the first connecting groove 11, realizing the quick installation, fixing and disassembly of the support plate 13, and improving the convenience of using the equipment.

[0032] like Figure 2 , Figure 5 As shown, this invention provides a multi-angle adaptive adjustment CT-assisted positioning mechanism. Both ends of the support plate 9 are provided with mounting grooves 21. A first support airbag 22 for supporting the patient's body is fixedly installed in the mounting groove 21. The first support airbag 22 includes a mounting part 25 and a support part 26 that are interconnected. The mounting part 25 is located in the mounting groove 21 and is fixedly connected to the support plate 9. The mounting part 25 is connected to a connecting pipe 24, which is connected to an external air supply device.

[0033] Specifically, after being inflated, the support part 26 is located outside the mounting groove 21. The support part 26 is distributed on both sides of the support plate 9. When there is no pressure on the support part 26, the upper surface of the support part 26 is higher than the upper surface of the support plate 9.

[0034] Specifically, the surface of the support portion 26 that does not come into contact with the patient is connected to multiple sets of second support airbags 23. The second support airbags 23 are cylindrical and are set at an angle with the surface of the support portion 26.

[0035] In practical application, when the support plate 9 rotates, the higher end of the support plate 9 exceeds the plane formed by the other support plates 9. At this time, the first support airbag 22 at the higher position on the support plate 9 is inflated through the connecting pipe 24. After the first support airbag 22 is inflated, it extends out of the mounting groove 21. The support part 26 extends to both sides of the support plate 9 and, after being inflated, contacts the patient's body. The support part 26 provides auxiliary support to the patient's body, increases the support area for the patient, thereby reducing the pressure on the patient's body at the support position, avoiding pressure injury to the patient's body and improving the patient's comfort. When not in use, the gas in the first support airbag 22 is extracted through the connecting pipe 24, and the first support airbag 22 will quickly retract into the mounting groove 21 to avoid affecting the subsequent reset of the support plate 9. When the first support airbag 22 is inflated, the second support airbag 23 is inflated at the same time. The second support airbag 23 supports the support part 26 of the first support airbag 22, thereby improving the support of the support part 26 for the patient's body.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
