Description

Technical Field

[0001] The utility model relates to the field of medical equipment, and in particular to a medical balloon size detection device based on machine vision. Background Art

[0002] The elderly are usually more susceptible to cardiovascular disease. The health threats and living costs caused by cardiovascular disease are increasing. Currently, cardiovascular disease can be treated with drugs, surgery and minimally invasive surgery. However, when cardiovascular disease reaches the middle and late stages, drug treatment has little effect. Interventional treatment and surgery will become the main treatment methods. Interventional treatment is favored by many cardiovascular disease patients because of its less trauma, less pain to patients, and quick recovery.

[0003] Medical balloon catheters are core components of devices used in cardiovascular interventional treatment. They can dilate blood vessels and deliver stents. During the treatment process, the stent is mainly brought to the narrow part of the blood vessel through the balloon. Air or contrast fluid is introduced into the balloon catheter to expand the balloon under pressure, which opens the narrow blood vessel and props up the stent so that it can always support the blood vessel. When the balloon is used in clinical treatment, the safety requirements are very high, which places high requirements on the size and structure of the balloon. Therefore, it is necessary to perform size detection on the balloon. Accurately measuring the size of the medical balloon can ensure that the balloon can correctly expand or compress the target area during the treatment, thereby improving the treatment effect. The accuracy of size detection helps to ensure the matching degree between the treatment device and the patient's lesion and improve the success rate of treatment. Safety will also be improved. The accuracy of balloon size detection is crucial to patient safety. Balloons that are too large or too small may cause complications, such as vascular lacerations and organ damage. By accurately measuring the balloon size, these potential risks can be avoided and the safety of treatment can be ensured. In addition, it can also promote equipment standardization. Research and standardization of medical balloon size will help promote the development of the medical device industry. Accurately measure balloon size and establish corresponding standards. These standards can also control product quality. Researching and testing medical balloon size can help manufacturers ensure product quality control. By establishing accurate size measurement methods and standards, the production process of balloon products can be verified and monitored to ensure that their sizes meet the specified requirements and improve product consistency and reliability. Accurate measurement of medical balloon size is also important for clinical research and data analysis. Medical professionals can evaluate the effects of different treatment options based on balloon size data and analyze the correlation between balloon size and treatment outcomes to optimize treatment strategies and provide better clinical decision-making basis.

[0004] Therefore, it is necessary to design a medical balloon size detection device to ensure patient safety, promote the development of the medical device industry, product quality control, and the accuracy and reliability of clinical research and data analysis. Utility Model Content

The stepper motor 22 is fixed on the cabinet 1. The stepper motor 22 is connected to the material tray 21 and drives the material tray 21 to rotate horizontally.

[0041] The robot system 3 is connected to the robot controller, and the robot system 3 is suitable for clamping the balloon 7 to be inspected on the tray 21, and sending the balloon 7 to the imaging system 4 for inspection;

[0042] The imaging system 4 is suitable for taking photos of the balloon 7 to be inspected at different angles and transmitting the photos to the computer system 5 for parameter comparison.

[0043] Specifically, as an optional implementation in this embodiment, Figure 3 As shown, the robot system 3 includes a base 31, a robot body 32 and a fixture 33;

[0044] The lower end of the robot body 32 is connected to the operating platform 11 via the base 31 , and the working end of the robot body 32 is connected to the fixture 33 .

[0045] In this embodiment, the robot body 32 and the clamp 33 are both conventional products that can be purchased directly on the market. The clamp 33 is a pneumatic clamp 33 that can pneumatically clamp the balloon 7. The robot body 32 can rotate to drive the clamp 33 to move from above the material tray 21 to the imaging system 4.

[0046] Specifically, as an optional implementation in this embodiment, Figure 4 As shown, the imaging system 4 includes a camera 42, a lens 43 and a bracket 41;

[0047] The bracket 41 is fixedly arranged on the operating table 11 , the lens 43 is arranged on the bracket 41 , the lens 43 faces the to-be-detected balloon 7 , the camera 42 is connected to the lens 43 , and the camera 42 takes a picture of the to-be-detected balloon 7 through the lens 43 .

[0048] Specifically, as an optional implementation in this embodiment, Figure 2 As shown, the operating table 11 is provided with a light source 8 , and the light source 8 is arranged opposite to the imaging system 4 .

[0049] By illuminating the balloon 7 with the light source 8 , the photo of the balloon 7 taken by the imaging system 4 can be clearer.

[0050] Specifically, as an optional implementation in this embodiment, Figure 2 As shown, a qualified balloon material bin 61 and a defective balloon material bin 62 are provided on the cabinet 1 . The qualified balloon material bin 61 forms a qualified material distribution hole on the operating table 11 , and the defective balloon material bin 62 opens an unqualified material distribution hole on the operating table 11 .

[0051] For the balloons 7 that have been tested, qualified balloons 7 are sorted into a qualified balloon material bin 61 , and unqualified balloons are sorted into a defective balloon material bin 62 .

[0052] The qualified balloon silo 61 and the defective balloon silo 62 have the same structure. The two silos are slidably matched on the cabinet 1. When the silos are full, the silos can be drawn out for cleaning.

[0053] The working process of the medical balloon size detection device based on machine vision of the utility model is as follows:

[0054] Turn on the power switch, then start the computer, open the balloon size detection software, and make a corresponding balloon detection template (if it is local and has a created template, you can directly read it) and recipe parameters according to the model of the balloon. After the template is made, click to start the detection. After the robot system 3 receives the signal, it clamps the balloon 7 on the tray 21 through the clamp 33, and drives the balloon 7 to move to the detection area between the imaging system 4 and the light source 8. After reaching the detection area, the tray 21 rotates a fixed angle under the drive of the stepper motor 22 to ensure that there is a balloon 7 at the clamping position. Then the robot system 3 clamps the balloon 7 and rotates it in the detection area for one circle. The camera 42 takes photos of the balloon 7 at different angles, and then uploads the photos to the computer system 5. The detection software is based on the above Transmit the picture for size detection, find the size of multiple pictures of the same balloon 7 and then get the average value, compare it with the parameters in the set formula, if it is within the parameter range, it is qualified, otherwise it is unqualified. After the measurement is completed, the measurement results are saved to the database, and the detection software sends different commands to the robot system 3 according to the measurement results. The robot system 3 puts the balloon 7 in different areas (qualified product area or unqualified product area) according to different commands, and then the robot returns to the initial point for the next measurement. The robot controller is used to monitor the robot position and give alarm feedback on whether the robot clamps and releases the balloon 7. The robot controller can also operate the robot movement to play the role of a teaching pendant. The emergency stop switch is used to stop the machine in an emergency. The size detection and classification of the balloon 7 can be completed through the above.

[0055] The medical balloon size detection device of the utility model is easy to operate and can perform size detection on various types of balloons by selecting or making detection templates of different balloons. The detection process is measured through template matching, the measurement speed reaches millisecond level, and the detection accuracy reaches ±0.05mm.
