OCT (optical coherence tomography) catheter airflow welding tool

The invention relates to an OCT (optical coherence tomography) catheter airflow welding tool. The welding tool comprises an air heater and is characterized in that airflow generated by the air heaterenters an airflow controller; the airflow controller feeds the airflow into a tee air pipe joint; one way of the tee air pipe joint is connected with a heater; the airflow enters a heating pipe afterbeing heated in the heater, and the heating pipe heats a heating groove; a catheter clamping block is installed at each of two ends of the heating groove, and a catheter is clamped in the heating groove by the catheter clamping blocks; the heating pipe is covered with a cooling block; other two ways of airflow in the tee air pipe joint enter an installation space of the cooling block via the air pipe joint, enter the cooling block from the lower part of the cooling block, and flow out of cooling holes in the cooling block to cool the heating pipe and prevent the temperature from being too high. The welding tool takes s
