Recent Patents on intervention auxiliary device of tracheal stent



The trachea is an essential part of the respiratory system. Lesions such as inflammatory granulomas cause Bronchial stenosis, which may be life-threatening. Tracheal stent placement is vital for treating airway stenosis, relieving dyspnea, and improving symptoms.



This paper reviews the patents of tracheal stent placement and removal and auxiliary devices for diagnosis in recent years (from 2007 to the present) and introduces the characteristics and development of tracheal stent implantation, treatment, and assistive removal devices. In order to meet the need for more rapid operation and cause less harm to the human trachea, the structure of the tracheal stent surgical device needs to be improved continuously.



This paper summarizes the research status of tracheal stent placement and removal and auxiliary devices for diagnosis and treatment in recent years and discusses the structural types and applications of tracheal stent auxiliary devices.



This paper summarizes the patent application of tracheal stent placement and removal and auxiliary devices for diagnosis and treatment at the present stage. This paper analyzes the main problems in its development and discusses the solutions to the problems and the future research direction.



Tracheal stent surgical devices need further improvement in mechanical design, control strategy, etc. Tracheal stent surgical devices should be developed into universal, semi-automatic, and multi-functional machines. The relevant patents of the auxiliary device of the tracheal stent need to be developed.
