A surgical instrument includes a member including a body engageable with a longitudinal element to fix the longitudinal element with the body. The member further includes a distal portion having a guide including an arcuate surface being engageable with the longitudinal element. An actuator is connected with the member to incrementally tension the longitudinal element. Surgical systems, implants, spinal constructs and methods are disclosed.

This application describes surgical instruments and implants for building a posterior fixation construct across one or more segments of the spinal column. More specifically, the application describes instruments and methods for building a posterior fixation construct across one or more segments of the spinal column in a minimally invasive fashion.

A system and method for stabilizing a spine of an animal subject involving a transverse rod installation instrument assembly for inserting a transverse rod on the spine of a subject percutaneously comprising: a first rod clamp extender mounted on a ipsilateral rod clamp and a second rod clamp extender mounted on a contralateral rod clamp wherein the ipsilateral rod clamp and the contralateral rod clamp are secured to a vertebra at the ipsilateral and contralateral pedicle; and a pivoting installation instrument pivotably mounted to the first rod clamp extender and the second rod clamp extender to pass a transverse rod percutaneously through a head portion of the ipsilateral side rod clamp and to the head portion of the contralateral rod clamp after passing through a spinous process of the vertebra through pivot axis “A” such that the transverse rod is secured at the head portion of the ipsilateral rod clamp and the head portion of the contralateral rod clamp.

More specifically, the application describes instruments and methods for building a posterior fixation construct across one or more segments of the spinal column in a minimally invasive fashion.

This application describes surgical instruments and implants for building a posterior fixation construct across one or more segments of the spinal column. Extension guides are provided that attach to bone anchors implanted within the spine. The extension guides have a guide channel that align with a rod channel in the anchor to help direct the rod to the anchor. Instruments are provided to aid in insertion and positioning or the rod.

Problem to be Solved A traverse that is percutaneously provided and a surgical instrument for percutaneously providing the transverse are provided. Solution A rod 10 is placed in each of two rod openings 113, 123 and a transverse bar 130 is inserted in two bar holes 111, 121. Set screws 140, 150 are screwed in screw holes 114, 124. The set screws 140, 150 press the transverse bar 130, thereby restraining the transverse bar 130 in the longitudinal direction. Since portions of the bar holes 111, 121 adjoin the rod openings 113, 123, the pressed transverse bar 130 contacts the rods 10 and pushes the rods 10 against the rod openings 113, 123. A protrusion 127 engages with the rods 10 to restrain hooks 110, 120 in the longitudinal direction and circumferential direction of the rods 10.

A percutaneous revision implant for percutaneously revising an existing implant located in the spine of a patient may include, for example, extending the existing implant construct to span additional portions of the spine of the patient. The percutaneous revision implant comprises a proximal end portion and a distal end portion. The proximal end portion comprises a connector having two opposable walls joined at one end to define a cavity having a first longitudinal axis. The cavity is suitable to receive and engage a rod of the existing implant. The percutaneous revision implant of the invention permits a medical practitioner to extend an existing implant construct without significantly disrupting or removing the existing implant or its component parts. A method of using same is also provided.

Certain embodiments of the invention relate to a surgical procedure resulting in the fusion of transverse processes. The disclosure herein presents novel approaches for accessing transverse processes of the spine, novel methods for the delivery of fusion material for the fusion of said transverse processes, and novel tools to facilitate the procedure. Certain embodiments of the invention include a graft delivery assembly, which has a delivery shaft, delivery sheath, and at least one curved rod. Bony material is position with a graft delivery assembly, in which retraction of the delivery shaft or sheath places the bone fusion material to the fusion site. The graft delivery assembly further includes features to decorticate and prepare the bone surface for fusion.

A medical robot system, including a robot coupled to an end effector element with the robot configured for controlled movement and positioning. The robot system includes a robot base having a display, a robot arm coupled to the robot base, wherein movement of the robot arm is electronically controlled by the robot base. The end-effector is coupled to the robot arm, containing one or more end-effector tracking markers. The system also includes a plurality of dynamic reference bases (DRB) attached to multiple patient fixture instruments, wherein the plurality of dynamic reference bases include one or more tracking markers indicating a position of the patient fixture instrument in a navigational space. The system also includes a first camera system and a second camera system, the first and second camera systems being able to detect a plurality of tracking markers.
