Abstract

The invention relates to a bronchial puncture wall-breaking device, which comprises an outer sheath tube, a head of a guide head is in a pointed cone shape, the tail of the guide head is coaxially connected with the front end of the outer sheath tube in a fastened mode, and the guide head is hollow and communicated with the interior of the outer sheath tube to form a channel; a puncture needle isused for being coaxially arranged in the channel in a penetrating mode and can reciprocate in the outer sheath tube so as to stretch in or out of the head of the guide head. The bronchial puncture wall-breaking device can penetrate through the bronchus wall, a wound can be enlarged and deepened, a path from the bronchus wall to a target focus is artificially established, and a biopsy sample can beobtained.

Description

Technical field [0001] The invention relates to medical equipment, in particular to a bronchial puncture and wall breaking device. Background technique [0002] The diagnosis and treatment of lung nodules have become more and more important for the early detection and treatment of lung cancer. The conventional lung nodule biopsy method uses percutaneous puncture to insert a puncture needle directly into the lung to obtain a biopsy sample. This puncture method has the risk of pneumothorax. Studies have shown that percutaneous puncture of the lung has a 20%-40% incidence of pneumothorax, and pneumothorax is a serious adverse reaction that may be fatal. Another safer way is to use bronchoscope to biopsy the lung nodules through the natural airway, which can reduce the risk of adverse reactions, but this method can only be applied to lung nodules with larger airways. [0003] Therefore, for those pulmonary nodules without obvious tracheal access through bronchoscopy, there is an urge...
