Abstract

It is the purpose of this report to design, develop, and evaluate a needle holder whose jaws improve needle-holding security without altering the geometry of the curved surgical needle. The configuration of the jaws of this new needle holder is curved, conforming to the curvature of the surgical needle. A biomechanical study of this curved surgical needle holder demonstrates that it holds the curved needle securely without needle deformation.

摘要

本报告的目的是设计、开发和评估一种持针器，其钳口在不改变弯曲手术针几何形状的情况下提高持针安全性。这种新型持针器的钳口形状是弯曲的，与手术针的曲率相符。对这种弯曲手术持针器的生物力学研究表明，它能牢固地夹持弯曲针而不会使针变形。
