The sharp edges of the box lock of the needle holder can inadvertently damage the suture during instrument ties. Compression of a monofilament nylon suture between the sharp edges of the box lock of a surgical needle holder damages the suture, reducing its breaking strength. This adverse effect has been eliminated by one manufacturer whose needle holder box lock has rounded edges and sufficient space to permit passage of the suture.
持针器针盒锁的尖锐边缘在器械打结过程中可能会意外损坏缝线。手术持针器针盒锁的尖锐边缘挤压单丝尼龙缝线会损坏缝线，降低其断裂强度。一家制造商已消除了这种不利影响，其持针器针盒锁边缘呈圆形且有足够空间允许缝线通过。
