Abstract
Rod bending instruments, systems, and methods thereof for robotic and navigated rod bending of a rod for spinal surgeries. A system for bending a spinal rod includes a rod bending assembly and an automatic or navigated feeding system. The rod bending assembly includes a bender box having a fixed coupling member and an actuated coupling member. A rod cutter is attachable to the fixed coupling member and a bending mandrel is attachable to the actuated coupling member, for example, over a sterile drape. The automatic or navigated feeding system is configured to feed a spinal rod into the rod bending assembly to bend and contour the spinal rod into a complex three-dimensional shape.
Claims20
A system for bending a spinal rod comprising:
- a rod bending assembly including a bender box and a bender assembly coupled to the bender box, the bender box includes a top plate having a fixed coupling member and an actuated coupling member, the bender assembly includes a rod cutter attachable to the fixed coupling member and a bending mandrel attachable to the actuated coupling member;
- and
- an automatic or navigated feeding system configured to feed a spinal rod into the rod bending assembly, and wherein the bender assembly is configured to bend and contour the spinal rod into a complex three-dimensional shape.
An automatic rod bender system comprising:
- a surgical robot comprising a base having transport handles and including a computer, a robot arm electronically coupled to the computer and moveable based on commands processed by the computer, and an end-effector coupled to the arm;
- and
- a rod bender assembly attachable to the transport handles of the surgical robot, the rod bender assembly comprising a bender box having a fixed coupling member and an actuated coupling member, a rod cutter attachable to the fixed coupling member, and a bending mandrel attachable to the actuated coupling member,
- wherein the end-effector is configured to hold one end of a spinal rod to automatically feed and rotate the rod through the rod bender assembly.
A method of bending a spinal rod comprising:
- providing a robot having a base with transport handles and including a computer, a robot arm electronically coupled to the computer and moveable based on commands processed by the computer, and an end-effector coupled to the arm;
- attaching a bender box to one transport handle of the robot, the bender box having a fixed coupling member and an actuated coupling member controllable by a power source and a data cable;
- attaching a bender assembly to the bender box by affixing a rod cutter to the fixed coupling member and affixing a bending mandrel to the actuated coupling member;
- securing a spinal rod to the end-effector;
- automatically feeding the spinal rod through the bender assembly to bend and contour the spinal rod.
