摘要： A clamp assembly for an external fixation system includes a first clamp member for engaging a first elongated member. The first clamp member includes a first jaw portion and a second jaw portion. The first and second jaw portions at least partially defining a laterally extending channel for receiving the first elongated member. The first and second jaw portions or members are connected by a hinge portion. The first jaw member includes a free end normally spaced apart from a free end of the second jaw a distance less than a diameter of the first elongated member. The first clamp member is elastically deformable to receive the first elongated member between the free ends of the first and second jaw members and into the laterally extending channel.

摘要： A clamp assembly for an external fixation system includes a first clamp member receiving a first elongated and a second clamp member receiving a second elongated member. The first clamp member includes a first fastener rotatably in a first direction to lock the first elongated member relative to the first clamp member. A second fastener connects the first and second clamp members. The second fastener is rotatable in the first direction to independently lock the second elongated member relative to the second clamp member. The first fastener is hollow and the second fastener passes through the first fastener.

摘要： An external fixation system for securing a first bone portion in a fixed relationship with respect to a second bone portion. The fixation system includes at least one cylindrical support rod and a plurality of universal clamp assemblies for engagement with at least one support rod. The fixation system additionally includes various other distinct components for interconnecting the support rod with bone pins engaged with the bone. Some of the other components are formed to include serrations for engaging corresponding serrations provided on the universal clamp assemblies. Some of the components include a cylindrical portion, whereas other of the components include a rod receiving portion adapted to receive the at least one support rod or one of the cylindrical portions. These interchangeable and distinct components allow for a greater degree of surgeon flexibility in producing a desired construction to secure bone portions with bone pins.

摘要： An external fixator for securing a first bone portion in a fixed relationship with respect to a second bone portion. The fixator includes a bone screw clamping assembly for receiving a first bone screw which is connected to the first bone portion and which includes a spherical portion. The fixator further includes a bone screw clamping assembly which is operable to receive a second bone screw which is connected to the second bone portion and which has a spherical portion. The fixator also includes a connection member having a main body portion and an internal module adjustably mounted within the main body portion. The internal module receives a spherical end of one of the bone screw clamps and selectively permits universal movement thereof. The internal module may be linearly adjusted within the connection member independently in first and second directions which are substantially perpendicular to one another. The fixator further includes a locking mechanism for preventing universal movement of the spherical portion.

摘要： An external fixator for adjustably securing first and second portions of a bone includes a ring assembly and a bone screw clamp assembly interconnected by a central body. The ring assembly secures one or more tension wires adapted to pass through the first portion of the bone. The bone screw clamp assembly secures one or more bone screws adapted to engage a second portion of the bone. The ring assembly includes a generally circular frame having a peripheral groove for securing a tension wire carriage anywhere therealong. The tension wire carriages are adjustable so that the tension wire may be positioned above or below the ring. One or more connector rods are used to rigidify the external fixator by interconnecting the ring assembly and the bone screw clamp assembly.
摘要翻译： 用于可调节地固定骨头的第一和第二部分的外部固定器包括由中心体相互连接的环组件和骨螺钉夹具组件。 环组件固定适于穿过骨的第一部分的一个或多个张力线。 骨螺钉夹具组件固定一个或多个适于接合骨的第二部分的骨螺钉。 环组件包括大致圆形的框架，其具有用于在任何地方固定张力丝托架的周边槽。 张力线支架是可调节的，使得张力线可以位于环的上方或下方。 一个或多个连接杆用于通过将环组件和骨螺钉夹具组件相互连接来固定外固定器。
