Devices and methods for bending or cutting implants are disclosed herein. In some embodiments, an instrument can convert a rotational input force (e.g., supplied by a powered driver tool) into movement of a first rod holder with respect to a second rod holder. Such movement can form a bend in a rod or other implant held by the first and second rod holders. Various mechanisms for converting this movement are disclosed, such as a worm drive mechanism and a conical gear mechanism, as are various types of rod holders, including orbiting rollers, lid-type rod holders, fixed and pivoting half-pipe rod holders, and full-pipe rod holders. In some embodiments, the instrument can also be used for cutting, for example by rotating a cutting wheel with respect to a cutting plate to cut a rod or other implant inserted through openings formed in the cutting wheel and the cutting plate.

A rod bender for bending a surgical rod includes first and second arms. The first arm includes first and second engaging portions. The second arm includes third and fourth engaging portions. The rod bender is reconfigurable between a first configuration in which the second and fourth engaging portions of the respective first and second arms engage the surgical rod such that spreading of the first and third engaging portions of the respective first and second arms bends the surgical rod in a first orientation and a second configuration in which the first engaging portion of the first arm and the fourth engaging portion of the second arm engage the surgical rod such that spreading of the second engaging portion of the first arm and the third engaging portion of the second arm bends the surgical rod in a second orientation opposite to the first orientation.

A multi-stage minimally invasive surgical procedure and associated instruments are disclosed. First, the surgical site is prepared. After preparation, the bone screws or anchors are attached to the bone. Subsequent to insertion of the screws, a rod or connecting member is positioned within the yoke portion of the bone screw. Caps are then placed in a pre-lock position within the yokes. The bone screws may be compressed together or distracted along the rod or connecting member, thereby setting the final spacing of the bones or bone segments. Finally the caps are moved to a final lock position to fix the screws to the rod or connecting member to maintain the bones in position relative to each other.

Systems providing robotic bending used to bend a surgical rod are disclosed. Such systems may include a processor and memory coupled with the processor. The memory includes computer readable program code so that when the computer readable program code is executed by the processor, the processor performs operations including providing a set of transformation points corresponding to respective attachment implants, generating a bend plan for the surgical rod based on the set of transformation points, and generating an image output to render the set of transformation points and the bend plan on a display. Related methods and computer program products are also discussed.

An adjustable articulating spinal rod system including a first elongated element secured to a first bone, a second elongated element secured to the spine, and an articulating joint connecting the first and second elongated elements. The articulating joint including a first movable joint, a second movable joint, and at least one locking mechanism. The first movable joint is coupled to the first elongated element and the second movable joint which is also coupled the second elongate element. The first and second movable joints are configured to allow polyaxial movement and rotation of the first elongated element with respect to the second elongated element. The at least one locking mechanism immobilizes the first and second movable joints in the locked position to secure the first elongate element in a position relative to the second elongate element and allow movement and rotation in an unlocked position.

Devices, Systems, and Methods for detecting a 3-dimensional position of an object, and surgical automation involving the same. The surgical robot system may include a robot having a robot base, a robot arm coupled to the robot base, and an end-effector coupled to the robot arm. The end-effector, surgical instruments, the patient, and/or other objects to be tracked include active and/or passive tracking markers. Cameras, such as stereophotogrammetric infrared cameras, are able to detect the tracking markers, and the robot determines a 3-dimensional position of the object from the tracking markers.

This invention relates to a surgery planning tool, which is not a patient implant, comprising an elongated body including at least a portion having the shape and the size of a spinal correction rod.

A posterior cervical fixation system including an occipital plate member, a cross connector, a pair of elongated spinal rods and a plurality of polyaxial screws. The occipital plate member configured for fixing to an occipital bone comprises an aperture to receive a bone anchor member to secure the occipital plate member to the occipital bone and at least one rod clamping element dimensioned to receive at least one spinal rod. The cross connector secures the pair of elongated spinal rods to vertebral bodies. The cross connector includes a pair of collet connectors and a cross bar that is configured to secure the pair of elongated spinal rods in a desired distance. Each polyaxial screw has an anchor head associated with a fastening member. The pair of elongated spinal rods is configured to extend along the vertebral bodies between the occipital plate member and at least one of the polyaxial screws.

Robotic rod benders are disclosed including a motor housing and a mechanical housing coupled with the motor housing. The motor housing may include first and second rod feeding/rotating motors, a brake motor, a bending motor, first and second rod feeding/rotating transmission inputs, a brake transmission input, and a bending transmission input. The mechanical housing may include a rod feeding/rotating subassembly, a brake subassembly, a bending subassembly, first and second rod feeding/rotating transmission outputs, a brake transmission output, and a bending transmission output. Separate motor and mechanical housings are also disclosed.
