A new quantitative measurement of surgical needle holder performance has been described that records the forces (clamping moment) applied by the needle holder jaws to curved surgical needles. This test has been used to determine the applied clamping forces of four different surgical needle holders made by one manufacturer. By relating the magnitude of the clamping moment of needle holder to the resistance to bending of curved surgical needles, we propose a new scientific basis for selecting surgical needle and needle holders for wound closure.
一种新的手术持针器性能定量测量方法已被描述，该方法记录持针器钳口施加于弯曲手术缝合针的力（夹持力矩）。此测试已用于确定由一家制造商生产的四种不同手术持针器所施加的夹持力。通过将持针器的夹持力矩大小与弯曲手术缝合针的抗弯曲性相关联，我们为伤口缝合选择手术缝合针和持针器提出了一种新的科学依据。
