Title: Nobuhiko Sugano: Innovator in Artificial Hip Prosthesis Technology

Introduction

Nobuhiko Sugano is a prominent inventor based in Suita, Japan. He has made significant contributions to the field of orthopedic prosthetics, particularly in the design of artificial hip prosthesis stems. With a total of 4 patents to his name, Sugano's work reflects a deep understanding of both engineering and human anatomy.

Latest Patents

Sugano's latest patents include a method for determining the shape of an artificial cementless hip prosthesis stem. This innovative approach allows for the creation of custom-made stems that fit well and fill the anatomical space, reflecting the unique characteristics of a patient's femur. The method utilizes computer calculations to generate models that comply with the individual curvature of the femur, which can often complicate the design process. By calculating the reverse course of how the stem is extracted from the femur, Sugano's models provide reliable options for surgeons. This custom-made stem can be confirmed in advance to ensure compatibility with the patient's anatomy.

Another notable patent is the design of an artificial cementless hip prosthesis stem. This invention features an inner construct that reacts to loads acting on the hip joint and an outer construct that transmits these loads to the femur. The design includes an inner body that interacts with the load from the neck and an outer body that is bell mouth-shaped, surrounding the inner body while extending towards the medullary cavity. The torsional rigidity of the outer body and leg is carefully regulated to optimize performance.

Career Highlights

Throughout his career, Sugano has worked with various companies, including Kabushiki Kaisha B.I. Tec and Mamoru Mitsuishi. His experience in these organizations has contributed to his expertise in developing advanced prosthetic technologies.
