Summary:A steerable arm of a surgical instrument for endoscopic surgery is tensible from a first position and a second position. The steerable arm is structurally biased to a first position, but limited to not fully meet the bias, to respond quickly upon actuation of the steerable arm towards a second position under the action of a force. The first position and the second position are determined by the length of the cable released from the spool. A holding force that does not fully meet the bias is provided by limiting the length of the cable that can be dispensed from the spool. 一种内窥镜手术的手术器械的可操纵臂，其能够从第一位置和第二位置绷紧。上述可操纵臂在结构上被偏置到第一位置，但被限制而不完全满足偏置，以在力的作用下将上述可操纵臂朝向第二位置促动时迅速响应。上述第一位置和第二位置由从线轴发放的线缆的长度确定。通过对可从线轴发放的线缆的长度进行限制来提供不完全满足偏置的保持力。
