[Usefulness of Long Shaft Stapler in Robot-assisted Thoracic Surgery Lung Resection]

Since national health insurance began to cover robot-assisted thoracoscopic surgery (RATS) for malignant lung tumors, malignant mediastinal tumors, and benign mediastinal tumors in Japan starting in 2018, the number of RATS performed domestically has increased rapidly. In the case of undiagnosed lung tumor, it is necessary to perform a thoracoscopic lung biopsy in the port arrangement for RATS lung resection in the case of undiagnosed lung tumor. The 2 ports are placed in the same 8th intercostal space and a 3 cm utility thoracotomy is added to the 4th or 5th intercostal space for the thoracoscopic lung biopsy. Because the assistant uses the stapler from the port, the distance to the target area increases. When it is converted to RATS for malignant lung diseases, the utility thoracotomy is often hidden by the robot arm and all ports placed in the 8th intercostal space are far from the target area. Furthermore, the assistant working space outside the patient's body is limited by the robot arms. The Signia stapling system has an adapter to extend the shaft. By attaching the adapter, the shaft can be extended by 10 cm. This permits easy handling of the stapler during both thoracoscopic biopsy and RATS lung resection.
