摘要： An assembly for connecting a support element to a bone. The assembly comprises: a bone screw having a head at one end of a threaded shaft; and a clamp comprising: a base at a first end of the clamp delimiting an opening for receiving the head of the bone screw; and at least two side members extending from the base towards a second end of the clamp. The head of the bone screw and the clamp are configured to allow the head of the bone screw to be inserted into the base from the direction of the first end at a first orientation of the base to the bone screw, and to retain an inserted bone screw within the base at a second orientation of the base relative to the bone screw.This allows the screw to be inserted into the bone without requiring prior assembly of the screw and clamp. It also allows later revision whereby the clamp can be removed from the screw without requiring an implanted screw to be removed from the bone.

摘要： A hook for joining a vertebra and a rod, comprising a main body (4) with a channel portion (10) and a hook portion (8). The channel portion (10) is for receiving a spinal support rod, and the hook portion (8) is for receiving vertebral tissue. The hook incorporates a clamp (6) which rotates about an axis so that a sharp tip of the clamp (6) can move towards and away from the free end of the hook portion, allowing a bone to be gripped within the hook portion (8) by the clamp (6).

摘要： A reamer for preparing a spinal upper facet to facilitate insertion of combined screw/washer implant, preventing bone damage and facet weakening, and also allowing possibility to place grafting so as to maximize implant stabilization. The reamer has shallow outer cutting surfaces to cut a groove for spike insertion; deep inner cutting surfaces to cut a cortical-penetrating bore for insertion of the screw, and a flat therebetween to limit penetration of these cutting surfaces.

摘要： A bone anchor assembly includes a bone anchor, a receiver member for receiving a spinal fixation element to be coupled to the bone anchor, a compression member positioned within the receiver member, and a closure mechanism including an outer set screw and an inner set screw. The outer set screw delivers a distal force to the compression member to fix the bone anchor relative to the receiver member. The proximal surface of the compression member has a shape configured to restrict deformation of the compression member arms including motion of the compression member arms relative to each other. The distal surface of the outer set screw has a shape that is complementary to the shape of the proximal surface of the compression member.

摘要： Various methods and devices for inserting a guidewire into the body are provided. In one embodiment, a guidewire insertion device is provided and includes and outer sheath having an outer surface and an inner lumen extending therethrough, and a dilator having an inner lumen extending therethrough and having a length greater than a length of the outer sheath. A guidewire can be configured to extend through the inner lumen of the dilator such that the guidewire is removably and replaceably disposable within the dilator and coupled thereto. A locking mechanism can be effective to selectively configure the guidewire between a locked position in which the guidewire is stationary relative to the dilator and an unlocked position in which the guidewire is movable relative to the dilator.
