Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a disposable hard bronchoscope sheath. Background Art

[0002] At present, rigid bronchoscopy in hospitals is one of the most effective technologies for diagnosing and treating airway diseases. This operation usually requires the patient to pass the rigid bronchoscope sheath through the mouth and insert it into the airway through the glottis under general anesthesia. In addition to maintaining airway patency, modern bronchoscope sheaths also have side holes at the operating end that are connected to the ventilator and have many interventional channels to facilitate the entry of bronchoscopes and other instruments into the airway, providing the operator with a clearer observation field to facilitate intubation, suction and handling of foreign bodies. Stent release, laser ablation, argon plasma coagulation and other treatments can also be performed under direct vision.

[0003] However, most existing bronchoscope sheaths are hollow stainless steel tubes, which are prone to oral and airway wall damage during use, leading to problems such as hemoptysis, pneumothorax and mediastinal emphysema, and there is a risk of disease transmission when recycled, because they need to directly enter the human respiratory tract and come into contact with the airway mucosa, and the examinees often have respiratory pathogen infections or respiratory tumors. Although the operating end has multiple interfaces, in actual use, it only needs to be connected to the anesthesia machine ventilation through the side hole and the bronchoscope insertion through the back hole. The high-frequency ventilation interface is obliquely inserted into the main pipeline, which not only affects clinical operations but also occupies space for other interfaces.

[0004] Therefore, it is necessary to provide a disposable rigid bronchoscope sheath to solve the above technical problems. Utility Model Content
