[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to a cardiovascular and cerebrovascular CT image auxiliary recognition device. Background Art

[0002] With the development of medical imaging technology, CT has become one of the indispensable and important tools in clinical diagnosis, especially in the diagnosis of cardiovascular and cerebrovascular diseases. CT is widely used in many aspects such as early disease detection, condition assessment and treatment effect monitoring because of its ability to provide high-resolution images; however, faced with the ever-increasing amount of medical data, doctors are facing increasing pressure when analyzing CT images.

[0003] Patent publication number CN114779483B discloses a cardiovascular CT image auxiliary recognition device, which can push films one by one to the surface of the backlight plate, making it convenient for doctors to check the films one by one. Doctors do not need to take down and place the films, which is more convenient. Moreover, after the doctor checks, the films are directly stored in the recycling mechanism, which is convenient for the doctor to check and organize the films. However, when the above patent is used, the doctor only views it with the naked eye, which makes it easy to ignore some details in the film, thereby affecting the doctor's assessment of the condition. Moreover, when the doctor finds that certain specific areas in the film image need further study, there is a lack of effective marking tools, making it difficult to record these important locations, which brings inconvenience to subsequent review. Summary of the invention

[0004] In view of this, the present invention provides a cardiovascular and cerebrovascular CT image auxiliary identification device, which can solve the shortcomings of the existing cardiovascular and cerebrovascular CT image auxiliary identification device, which only relies on the doctor's naked eyes to easily ignore the details in the film when in use, and lacks effective marking tools, causing inconvenience to subsequent review.

[0034] See also Figure 5-Figure 7 As shown, the stabilizing mechanism includes a magnetic block I901, an electric push rod II902, a magnetic block II903 and a push-pull switch 904; magnetic blocks I901 are installed on the slide rails I501 and II503 at intervals; the film 101 is placed in the limit frame 3, the magnetic block I901 on the slide rail I501 is aligned with the longitudinal dividing line in the film 101, and the magnetic block I901 on the slide rail II503 is aligned with the transverse dividing line in the film 101; the front side of the slider I502 and the top of the slider II504 are connected to electric push rods II902, and the number of electric push rods II902 is three; the telescopic rod of the electric push rod II902 is connected to a magnetic block I901. Block II 903, magnetic block II 903 is used to attract magnetic block I 901 to stabilize the magnifying glass 7; a push-pull switch 904 for controlling the electric push rod II 902 is installed on the slider II 504, and the push-pull switch 904 is electrically connected to the electric push rod II 902. When the push-pull switch 904 is pushed downward, the push-pull switch 904 controls the electric push rod II 902 on the slider I 502 to drive the magnetic block II 903 away from the magnetic block I 901. When the push-pull switch 904 is pushed upward, the push-pull switch 904 controls the electric push rod II 902 on the slider II 504 to drive the magnetic block II 903 away from the magnetic block I 901.

[0035] When in use, the film 101 is pushed to the left into the limit frame 3 so that the film 101 is covered by the glass 4 in the limit frame 3. Then the medical staff pulls the slider II504 to slide on the slide rail II503, thereby driving the slide frame I6 and the magnifying glass 7 to move synchronously, so as to adjust the height of the magnifying glass 7. At the same time, the slider II504 will drive the electric push rod II902 and the magnetic block II903 thereon to move synchronously. When the magnetic block II903 moves to contact the magnetic block I901 on the slide rail II503, the magnetic block I901 on the slide rail II503 will use magnetic force to attract the magnetic block II903, so as to limit the electric push rod II902, the slider II504, the slide frame I6 and the magnifying glass 7, so as to stabilize the magnifying glass 7. The height of the magnifying glass 7 is adjusted so that the magnifying glass 7 is located in front of one of the small areas in the film 101. The medical staff then confirms whether the height of the magnifying glass 7 is at the same height as the small area to be viewed in the film 101. If they are at the same height, no additional operation is required. If they are not at the same height, the medical staff pushes the push-pull switch 904 upward to control the electric push rod II 902 on the slider II 504 to drive the magnetic block II 903 away from the magnetic block I 901 on the slide rail II 503, so that the magnetic block I 901 on the slide rail II 503 releases the limit of the electric push rod II 902, the slider II 504, the sliding frame I 6 and the magnifying glass 7. The above operation is then repeated to adjust the height of the magnifying glass 7 again. After the magnifying glass 7 moves, the push-pull switch 904 is reset, so that the push-pull switch 904 controls the electric push rod II902 on the slider II504 to drive the magnetic block II903 to move and reset. When the magnetic block II903 moves to contact with other magnetic blocks I901 on the slide rail II503, the above operation is repeated again until the position of the magnifying glass 7 is at the same height as the small area to be viewed in the film 101; when the position of the magnifying glass 7 and the small area to be viewed in the film 101 are adjusted to the same height, the medical staff pulls the slider II504 to drive the slide rail II503 and the slider I502 to slide on the slide rail I501, thereby driving the sliding frame I6 and the magnifying glass 7 to move synchronously, so as to adjust the magnifying glass 7, and at the same time, the slider Ⅰ502 will drive the electric push rod Ⅱ902 and the magnetic block Ⅱ903 thereon to move synchronously. When the magnetic block Ⅱ903 moves to contact the magnetic block Ⅰ901 on the slide rail Ⅰ501, the magnetic block Ⅰ901 on the slide rail Ⅰ501 will use magnetic force to attract the magnetic block Ⅱ903, thereby limiting the electric push rod Ⅱ902, the slider Ⅰ502, the slide rail Ⅱ503, the slider Ⅱ504, the sliding frame Ⅰ6 and the magnifying glass 7, so as to stabilize the position of the magnifying glass 7, so that the magnifying glass 7 is located in front of one of the small areas in the film 101, and then the medical staff confirms whether the position of the magnifying glass 7 is in front of the small area to be viewed in the film 101: if it is in front, no additional operation is required;If it is not directly in front, the medical staff will push the push-pull switch 904 downward, so that the push-pull switch 904 controls the electric push rod II 902 on the slider I 502 to drive the magnetic block II 903 away from the magnetic block I 901 on the slide rail I 501, so that the magnetic block I 901 on the slide rail I 501 releases the limit of the electric push rod II 902, the slider I 502, the slide rail II 503, the slider II 504, the sliding frame I 6 and the magnifying glass 7, and then repeat the above operation to adjust the position of the magnifying glass 7 again, and reset the push-pull switch 904 after the magnifying glass 7 moves, so that the push-pull switch 904 controls the electric push rod II 902 on the slider I 502 to drive the magnetic block II 90 3 Move and reset. When the magnetic block II 903 moves to contact with other magnetic blocks I901 on the slide rail I 501, repeat the above operation again until the position of the magnifying glass 7 is directly in front of the small area in the film 101 that needs to be viewed. When the magnifying glass 7 is directly in front of the small area in the film 101 that needs to be viewed, the medical staff can rotate or reverse the electric control knob 802 to control the telescopic rod of the electric push rod I 801 to extend or shorten. When the telescopic rod of the electric push rod I 801 is extended, the electric push rod I 801 will drive the sliding frame I 6 and the magnifying glass 7 away from the film 101. When the telescopic rod of the electric push rod I 801 is extended, the electric push rod I 801 will drive the sliding frame I 6 and the magnifying glass 7 away from the film 101. When shortened, the electric push rod Ⅰ801 will drive the sliding frame Ⅰ6 and the magnifying glass 7 to approach the film 101, so that the distance between the magnifying glass 7 and the film 101 can be adjusted until the distance between the magnifying glass 7 and the film 101 is adjusted to be convenient for medical personnel to watch. After the adjustment, the medical personnel can watch the designated small area in the film 101 through the magnifying glass 7 and the glass 4, and the magnifying glass 7 can magnify the content of the small area of ​​the film 101, which can make it more convenient for medical personnel to watch the details in the film 101, thereby preventing some details in the film 101 from being ignored. When the medical personnel need to mark the special content in the film 101 To record time, you can use a water-based marker to mark the position on the glass 4 that is aligned with the special content of the film 101. When you review it later, you only need to look at the mark on the glass 4 to quickly find the special content in the film 101. When the designated small area in the film 101 is viewed, the medical staff can repeat the above operation to view the content of other areas in the film 101. When the content of the film 101 is completely viewed, the film 101 is pulled out of the limit frame 3 to the right, and the position of the slider Ⅰ502 on the slide rail Ⅰ501 is reset. When you need to remove the mark on the glass 4, you only need to wipe it off with a wet cloth. ;

[0036] See also Figure 8As shown, it also includes a conveying mechanism, which includes a servo motor 10 and a conveying roller 11; the servo motor 10 is arranged on the right side of the lower front side of the light board 2; a conveying roller 11 is rotatably arranged on the right side of the limit frame 3, and a gap is provided between the conveying roller 11 and the light board 2 for the film 101 to pass through, and the conveying roller 11 is used to convey the film 101 into the limit frame 3, and the conveying roller 11 is connected to the output shaft of the servo motor 10.

[0037] When it is necessary to push the film 101 to the left into the limit frame 3, the servo motor 10 can be started to drive the conveying roller 11 to rotate, and then the left end of the film 101 is extended between the conveying roller 11 and the light board 2, so that the film 101 contacts the conveying roller 11 and the light board 2, so that the conveying roller 11 conveys the film 101 to the left into the limit frame 3. In this way, it is convenient for medical staff to put the film 101 into the limit frame 3. After the film 101 completely enters the limit frame 3, the servo motor 10 is turned off; thereafter, when it is necessary to pull the film 101 out of the limit frame 3 to the right, the servo motor 10 can be started to drive the conveying roller 11 to rotate in the opposite direction, so that the conveying roller 11 conveys the film 101 to the right to leave the limit frame 3. In this way, it is convenient for medical staff to take the film 101 out of the limit frame 3. After the film 101 leaves the limit frame 3, the servo motor 10 is turned off, and then the film 101 can be taken out.

[0038] See also Figure 8 and Fig. 9 As shown, it also includes a memory tour mechanism, which includes an identification component 12, a button 13 and a recording component; the identification component 12 is arranged on the upper right side of the sliding frame Ⅰ6, and the identification component 12 is composed of a camera and a data analysis module. The content on the film 101 is photographed by the camera, and the photographed content is analyzed and recorded by the data analysis module. The electric push rod Ⅰ801 is electrically connected to the identification component 12; a button 13 is arranged in the middle of the front side of the electric control knob 802, and the button 13 is electrically connected to the identification component 12; the recording component includes a connecting frame 14, a distance sensor The distance sensing module 15 and the connecting plate 16 are connected, and a connecting frame 14 is connected between the two electric push rods I801. A distance sensing module 15 is connected in the middle of the connecting frame 14. The rear end of the distance sensing module 15 is flush with the rear end surface of the magnifying glass 7. The connecting plate 16 is connected to the left side of the slider II504. The distance sensing module 15 is used to sense the distance between the connecting plate 16 and the fixed distance between the connecting plate 16 and the film 101, thereby obtaining the distance between the magnifying glass 7 and the film 101. The button 13, the electric push rod I801 and the identification component 12 are all electrically connected to the distance sensing module 15.

[0039] When the electric push rod Ⅰ801 drives the sliding frame Ⅰ6 and the magnifying glass 7 away from or close to the film 101, the electric push rod Ⅰ801 will drive the connecting frame 14 and the distance sensing module 15 away from or close to the connecting plate 16, so that the distance between the distance sensing module 15 and the connecting plate 16 changes; when the medical staff has finished viewing the designated small area in the film 101, the medical staff can press the button 13 once, so that the button 13 controls the recognition component 12 to recognize and record the content in the designated small area of ​​the film 101, and the button 13 will control the distance sensing module 15 to pass The distance between the distance sensing module 15 and the film 101 is obtained by sensing the distance between the connecting plate 16, and then the fixed distance between the connecting plate 16 and the film 101 is added, so as to obtain the distance between the distance sensing module 15 and the film 101, and then the distance between the magnifying glass 7 and the film 101 is obtained. Then the distance sensing module 15 will record the distance between the magnifying glass 7 and the film 101; then, when the content in the small area on the film 101 is reviewed, the content in the designated small area of ​​the film 101 is automatically identified by the identification component 12, so that the identification component 12 can control the electric push rod Ⅰ801 The telescopic rod automatically extends or shortens, thereby driving the sliding frame Ⅰ6 and the magnifying glass 7 away from or close to the film 101, thereby adjusting the distance between the magnifying glass 7 and the film 101. When the sliding frame Ⅰ6 and the magnifying glass 7 are away from or close to the film 101, the electric push rod Ⅰ801 will drive the connecting frame 14 and the distance sensing module 15 away from or close to the connecting plate 16, so that the distance between the distance sensing module 15 and the connecting plate 16 changes. When the distance sensing module 15 senses the distance between the connecting plate 16, plus the fixed distance between the connecting plate 16 and the film 101, it is equal to When the distance between the magnifying glass 7 and the film 101 is previously recorded, the distance sensing module 15 will control the telescopic rod of the electric push rod Ⅰ801 to stop extending or shortening, thereby stabilizing the distance between the magnifying glass 7 and the film 101. In this way, when the medical staff reviews the content of a small area on the film 101, the distance between the magnifying glass 7 and the film 101 can be automatically adjusted to be consistent with the previously recorded distance, so that the medical staff can review the content of the small area on the film 101, and there is no need to manually adjust the distance between the magnifying glass 7 and the film 101 again during the review.

[0041] When in use, a dry sponge strip 21 and a wet sponge strip 21 can be embedded in the two installation frames 20 respectively, wherein the dry sponge strip 21 is embedded in the left installation frame 20, and the wet sponge strip 21 is embedded in the right installation frame 20; when it is necessary to erase the mark on the glass 4, the medical staff can push the push-pull switch 904 downward, so that the push-pull switch 904 controls the electric push rod II 902 on the slider I 502 to drive the magnetic block II 903 away from the magnetic block I 901 on the slide rail I 501, and then press the slide frame II 18 to move backward, the spring 19 is compressed, thereby driving the installation frame 20 and the sponge strip 21 to move backward, so that the sponge strip 21 is attached to the surface of the glass 4, and then the slide rail II 503 is pulled to move to the right, thereby driving the slider I 502, the guide rod 17, the slide frame II 18, the spring 19, the installation frame 20 and the sponge strip 21 to move to the right, so that the wet sponge strip 21 is used to wipe off the marks on the surface of the glass 4, and the dry sponge strip 21 is used to wipe off the water marks on the surface of the glass 4. In this way, the marks on the glass 4 can be wiped off, thereby cleaning the surface of the glass 4. After the marks on the glass 4 are completely wiped off, the sliding frame Ⅱ18 is released, and the spring 19 returns to its original state. The spring 19 drives the sliding frame Ⅱ18, the mounting frame 20 and the sponge strip 21 to move forward and reset, so that the sponge strip 21 is separated from the surface of the glass 4, and then the slide rail Ⅱ503 is pulled to move to the left and reset, thereby driving the slider Ⅰ502, the guide rod 17, the sliding frame Ⅱ18, the spring 19, the mounting frame 20 and the sponge strip 21 to move to the left and reset. Finally, the medical staff resets the push-pull switch 904, so that the push-pull switch 904 controls the electric push rod Ⅱ902 on the slider Ⅰ502 to drive the magnetic block Ⅱ903 to approach the magnetic block Ⅰ901 on the slide rail Ⅰ501.
