A bone staple () for securing a first bone region (A) to a second bone region (B) includes a staple body () having a first leg section (), a second leg section (), and a connector section (). The first leg section () is insertable into the first bone region (A). The second leg section () is insertable into the second bone region (B). The connector section () connects the first leg section () to the second leg section (). The connector section () includes a deformable region (A) that is movable from a first configuration (A) in which the leg sections () () are spaced apart a first distance () and a second configuration (B) in which the leg sections () () are spaced apart a second distance () that is less than the first distance (). In one embodiment, compression of the deformable region (A) causes the deformable region (A) to move from the first configuration (A) to the second configuration (B). As a result of this design, the bone staple () can easily be moved from the first configuration (A) to the second configuration (B). The deformable region (A) can be substantially square ring shaped and can define a region aperture (D) that is substantially square in the first configuration (A). Further, the deformable region (A) can be substantially oval ring shaped and the region aperture (D) can be generally rectangular shaped in the second configuration (B).

An apparatus for creating an electrical connection with a surgical tool is provided that is capable of engaging the shafts of rotatable surgical tools having varying diameters. In one aspect, the apparatus includes a body of nonconductive material connected to a pair of spaced, electrical contact members that provide two spaced points of contact with the tool shaft. In another aspect, a contact arm is provided which pivots within a slot formed within a housing to receive larger diameter tool shafts. Additionally, the contact arm closes an opening on the housing and resiliently shifts to an open position as the contact arm is brought into engagement with the tool shaft. A method of connecting a conductor assembly to a rotatable tool shaft is also provided which includes using tension in the conductor assembly to resist rotation of a gripping end of the assembly connected to a rotatable tool.

Electrical connector for surgical systems

A motion interface structure for use with a pedicle screw is provided, the motion interface structure defining a central passage having an internal face. A helical thread is formed on at least a portion of the internal face of the central passage. The motion interface element is designed to cooperate with an upstanding region of a pedicle screw. The upstanding region includes a threaded region that is adapted to threadingly engage the helical thread associated with the motion interface element. The motion interface element may take the form of a spherical element or a universal joint mechanism. The pedicle screw and motion interface element may be incorporated into a spinal stabilization system that includes one or more additional pedicle screw/motion interface element subassemblies. The spinal stabilization system may also include a dynamic stabilizing element that provides clinically efficacious results.

Pedicle screw assembly with bearing surfaces

A pedicle screw is provided that includes an upwardly extending collet. The collet may include downwardly extending slots that define deflectable segments therebetween. When a spherical element or other structure, e.g., a non-dynamic stabilizing element, is positioned around the collet, introduction of a set screw causes outward deflection of the upstanding segments into engagement with the spherical element. A snap ring may be interposed between the collet and the spherical element to facilitate positioning therebetween. In an alternative embodiment, a non-slotted collet is employed. In such embodiment, the collet and the spherical element may be threadingly engaged and may include a snap ring therebetween. The pedicle screw subassemblies may be incorporated into a spinal stabilization system which may include a dynamic stabilizing member to provide clinically efficacious results.
