摘要： An adjustable reamer spindle is provided to aid the surgeon in controlling the instrument. The reamer spindle is easily disassembled for cleaning. The spindle has a repositionable handle, a locking ring, and an elastic device. The elastic device biases against a handle locking mechanism that locks the repositionable handle at angular positions about an axis of the spindle. The elastic device further biases a locking ring into a locked position. The locking ring aids in holding the reamer spindle together. Removal of the locking ring against an elastic bias of the elastic means unfastens an end of the assembly in order to facilitate disassembly and/or cleaning. Adjustment of the position of the handle about the spindle enables the palm/grip of each hand to be changed in order to provide maximum control in different orientations. The adjustment is desirable in order to accommodate operating on the left or right side of the patient, standing behind or in-front of the patient, or the use of a different surgical approach. Further, adjustment is important to accommodate the differing needs of surgeons who are naturally left or right handed.

摘要翻译： 提供可调节铰刀主轴，以帮助外科医生控制仪器。 铰刀主轴容易拆卸清洗。 主轴具有可重新定位的手柄，锁定环和弹性装置。 弹性装置抵靠手柄锁定机构偏置，该手柄锁定机构将可重定位手柄锁定在围绕心轴的轴线的角位置处。 弹性装置进一步将锁定环偏压到锁定位置。 锁定环有助于将铰刀主轴固定在一起。 抵抗弹性装置的弹性偏压去除锁定环解除组件的端部以便于拆卸和/或清洁。 手柄围绕主轴的位置的调整使得能够改变每只手的手掌/握柄，以便在不同的取向上提供最大程度的控制。 为了适应在患者的左侧或右侧的操作，站在患者的后方或前方，或者使用不同的手术方法，该调整是可取的。 此外，调整对于适应自然左手或右手的外科医生的不同需求是重要的。
