Endoscopic surgical instrument coupler with manual drive for multiple portions of steerable arm

The steerable arm 403 has two bends, each bending in a different direction. Two spools (1701) are used, each spool (1701) controlling the cable (1501) to tighten one of the bends. In order to manually straighten the steerable arm 403, the drive gear 2601 can be individually rotated and the spool gea...

Summary:The steerable arm 403 has two bends, each bending in a different direction. Two spools (1701) are used, each spool (1701) controlling the cable (1501) to tighten one of the bends. In order to manually straighten the steerable arm 403, the drive gear 2601 can be individually rotated and the spool gear of the spool 1701 can be rotated to roll up the cable 1501. The driving gear can be moved to be disengaged from the spool gear; and the drive gear can be moved back to remesh with the spool gear. 可操纵臂403具有两个弯曲部，每个弯曲部沿着不同的方向弯曲。使用两个线轴1701，每个线轴1701控制线缆1501来绷紧其中一个弯曲部。为了手动拉直可操纵臂403，可以单独转动驱动齿轮2601而转动线轴1701的线轴齿轮以卷起线缆1501。可以移动驱动齿轮至与线轴齿轮脱离啮合；且可以移回驱动齿轮至与线轴齿轮重新啮合。
