 Objective:Successful endoscopic surgery for intracerebral hemorrhage has previously been hampered by impaired visualization during the operation to remove the clot, leading to a relatively low removal efficiency for hematomas. However, in multiple case series, intracerebral hematomas have been reported to be removed using endoscopic visualization. Although using tubular retractors in cranial surgery is one technique to gain access to deep-seated lesions, it is difficult to confirm the depth of the retractor's sheath in the surgical field using only the outer sheath. We built various-sized cylinders, developed by the Japan Science and Technology Agency's(JST)program for revitalization promotion, with scales that are visible during both endoscopic and radiographic procedures. We report the use of these cylinders in clinical cases.

 Method and Results:The JST-developed cylinders benefit from new techniques for plating and tantalum film implantation used to form tubes made of fluorinated ethylene propylene. We successfully removed various hematomas using these cylinders, as we were able to clearly visualize the border of the brain parenchyma and the depth of the hematoma using the cylinder.

 Conclusion:Cylinders with visible scales for both endoscopic and radiographic uses developed by the JST programs may provide greater patient safety during endoscopic surgery. We next plan to improve the hardness, length, and smoothness of the groove on the cylinder.
