Outline of Final Research Achievements

This study was conducted with the aim of quantifying the skill involved in the insertion of a puncture needle in dialysis treatment. We propose a novel approach based on the characteristics observed in the posture and force of the puncture needle, using miniature sensors mounted on a puncture needle. We evaluated its possibility using a simulated skin-blood vessel model in a laboratory experiment. The subjects were skilled dialysis practitioners and novices with knowledge but no practical experience. The experimental tasks were needle insertion in regular dialysis or buttonhole puncture. The effectiveness of this method was demonstrated by revealing the skill difference in the comparison. The difference in the penetration angle and gripping force trends during dialysis needling seemed to represent their technical skillfulness.

Academic Significance and Societal Importance of the Research Achievements

穿刺は伝承が困難な医療手技のひとつともいわれるが、熟練者が有する技量の感覚を定量的なデータに基づき記述できれば、医療施設における手技の継承に有効である。また、自動穿刺装置等の将来技術への貢献が期待できる。現行、所定の刺入角度を再現することが求められる手技においても、針の状況を簡易にモニタする方法として適用が考えられる。事例、症例との関連でデータを蓄積していけることも重要な要件となり、本研究成果はそのための一方法を提案しうる。将来的に安全確実で治療効率の高い医療技術の実現に繋がる。
