PROBLEM TO BE SOLVED: To solve the problems that: a conventional surgical needle needs to shift a surgical needle at each suture when the frequency of suture is high, it takes time and when a suture region is minute, labor is required for determination of a surgical needle implantation position and implantation at each suture.SOLUTION: A surgical needle is such that: one side of a surgical needle formed in a semi-circular arch shape is extended in a curve direction followed by forming at least one roll of a spiral shape with a rolling width so as to implant the surgical needle into a tissue to be sutured and proceed suture while rotated and inevitably, a second implantation position is determined before pulling out a surgical needle base end part from the tissue, and position correction for performing appropriate suture can be minimized and consequently, a suture time becomes shorter than that in a conventional example.COPYRIGHT: (C)2014,JPO&INPIT【課題】 従来の縫合針では、1回縫合する毎に縫合針を持ち替えなければならず、縫合回数が多い場合は時間を要し、また、縫合部位が微小な場合には縫合毎に縫合針刺入位置の決定および刺入に労力を要する。【解決手段】半円弧状に形成した縫合針の一方を曲線方向に伸張し、巻き幅を持った螺旋状に一巻以上形成することで、縫合したい組織に縫合針を刺入し回転させながら縫合を進めていくと、縫合針基端部が組織より抜かれる前に2回目の刺入位置が必然的に決まり、また適切な縫合を行うための位置修正を最小限にとどめることができ、結果として従来例より縫合時間が短縮される。【選択図】図1
