Abstract
Objective To explore the development status of key technologies in capsule endoscopy industry and provide references for optimizing industrial structure and allocation of innovative resources.Method IncoPat patent databases and advanced analysis tools at home and abroad reveal the development trend,technology development path,and focus/hot areas of the capsule endoscopy industry through time trend analysis,technology roadmap,patent strength,patent value analysis and other means.Results From 2003 to 2022,a total of 4 325 patents were applied for capsule endoscopy in the world,and the total number of patent applications in the 6 major fields of capsule endoscopy in China is the largest,and has shown rapid growth in recent years.In the technological development path,7,9,8,11,8 and 6 core patents were selected in the field of image acquisition,image processing,control technology,positioning technology,transmission technology and power supply technology,mainly from Olympus,Meriton,Anhan technology,Kingsoft technology and other head enterprises;the key technology hotspot migration chart shows that the number of patents from 2003 to 2019 accounted for 75%of the total number of patents,and the migration speed of the hot spots of control technology is higher than the reference line.3D,wireless,magnetic field is the key technology research focus;artificial intelligence,magnetic field,wireless are the key technology research hotspot.Conclusion In the world,China has the largest total number of patent applications in 6 key technology areas of capsule endoscopy;control technology has become a hot key technology;clear,accurate,efficient,intelligent and safe are the key technology development directions.关键词
