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 a n 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n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。

摘要： A disposable reamer is provided, made up of a base and a thin-walled, perforated cutting body of flat metal stock affixed thereto. The base and body may be molded together or assembled together in a mechanical manner. The body is optionally formed so as to comprise a plurality of appendages connected at a center so as to improve die forming of the body into a final desired shape while at the same time minimizing stress-induced deformation in the body.

摘要： A surgical tool holder 12 and tool system 10 is provided. The surgical tool holder (12) is adapted to connect to a tool support (14) having an interface receiver (36). The tool support provides a mount for a surgical tool head. The tool holder (12) includes a center rod (20), a tool interface (28) and a quick connect mechanism (50). The center rod (20) has a first shank end (24) and a second tool end (26). The tool interface (28) is disposed on the tool end (26) of the center rod (20). The tool interface (28) has at least one transversely extending portion (44, 44a), extending radially outward, beyond the diameter of the center rod (20) at the tool end (26). The interface (28) is adapted to engage with the interface receiver (36). The quick connect mechanism (50) is disposed on the center rod (20) to move in a rotationally-constrained manner thereon proximate the tool interface (28). The mechanism (50) includes protrusions (66) biased to bear against and engage the tool support (14) when the tool support is engaged with the tool interface (28). This securely holds the tool support (14) and prevents its relative rotation with respect to the tool holder (12).
摘要翻译：提供外科手术工具架12和工具系统10。手术工具保持器（12）适于连接到具有接口接收器（36）的工具支撑件（14）。刀具支架为外科手术刀头提供一个安装座。工具架（12）包括中心杆（20），工具接口（28）和快速连接机构（50）。中心杆（20）具有第一柄端（24）和第二工具端（26）。工具接口（28）设置在中心杆（20）的工具端（26）上。工具接口（28）具有至少一个横向延伸部分（44,44a），其径向向外延伸超过工具端（26）处的中心杆（20）的直径。接口（28）适于与接口接收器（36）接合。快速连接机构（50）设置在中心杆（20）上以在旋转约束的方式上靠近工具接口（28）移动。机构（50）包括当工具支撑件与工具接口（28）接合时被偏压以抵靠并接合工具支撑件（14）的突起（66）。这可靠地保持工具支撑件（14）并防止其相对于工具架（12）的相对旋转。

摘要： A guided reamer (10) has a central cannulation (12, 12a) adapted to receive a drill pin (14) secured in a manner which is axially aligned with the stem (22) of the bulbus bone joint (20). The reamer (10)has a profile cutting form (24) with cutting teeth (40) formed therein for cutting a form of a defined profile. The reamer (10) has a circumferential rim (34) having rim cutting teeth (36) disposed to cut to an outside of the rim and an inside of the rim, having face cutting teeth (37) adapted to cut an annular channel into bone and a plurality of planing teeth (52) radially disposed on an internal surface adjacent an axial end boss (44). The cannulation (12, 12a) is supported at the apex of the cutting form (24) and is formed in a guide assembly (70, 70′) affixed to the apex. The guide assembly (70, 70′) is adapted for imparting rotation to the reamer (12). The reamer (10) is adapted to be supported by a cannulated reamer handle (74) having a bayonet locking device (76) capable of locking the handle (74) to the guide assembly (70, 70′) of the cannulated reamer (10) and a corresponding central cannulation (86), permitting the drill pin (14) to pass at least part way therethrough.
