Description

Special flushing and sucking double-cavity tube for thoracoscopic sympathetic nerve operation Technical Field The invention relates to the technical field of medical appliances, in particular to a flushing and sucking double-cavity tube special for thoracoscopic sympathetic nerve operation. Background Thoracoscopic sympathetic nerve surgery is an effective minimally invasive method for treating diseases such as hand perspiration, head and face hyperhidrosis, partial Raynaud's disease and the like. An electrocautery hook is used for electrocautery cutting or blocking of the thoracic sympathetic nerve trunk in the operation. The operation space is narrow, and the operation space is close to important blood vessels (such as odd veins and intercostal blood vessels) and viscera, so that the precision and the safety of the operation apparatus are extremely high. Currently, monopolar electrocoagulation hooks and independent attractors are commonly used in combination in surgery. The smoke and a small amount of bleeding generated during the electrocoagulation need to be frequently switched to be attracted by the instrument, so that the smoothness of the operation is affected, and the operation time is prolonged.
