Abstract
Smart surgical instruments, systems, and methods for correcting a spinal deformity. The smart instruments are configured to sense and measure data, for example, related to screw insertion torque, segmental and global spine stiffness, correction force, rod reduction force, spinal alignment, or other metrics, which provide objective intraoperative data to the surgeon in real time. This data helps ensure that each action taken during the surgery is as precise as possible, minimizing risks and improving the effectiveness of the intervention.
Claims20
A smart instrument for correcting a spinal deformity comprising:
- a rod pusher configured to push a spinal rod into an implant;
- a force-sensing adapter assembly configured to sense and measure mechanical loads in real-time, the force-sensing adapter assembly includes a mechanical housing including a pair of half nuts configured to engage or disengage from the rod pusher and a load cell configured to accurately measure force without permanent deformation, and an electronic housing including a printed circuit board assembly electronically connected to the load cell;
- a battery cartridge receivable in the electronic housing to power the force-sensing adapter;
- an access tower for coupling the force-sensing adapter to the implant;
- and
- a locking cap driver positionable through the rod pusher.
A smart instrument system for correcting a spinal deformity comprising:
- a surgical robotic and navigation system having an on-board computer with software executed by one or more processing units;
- a force-sensing instrument configured to sense and measure mechanical loads in real-time while the instrument is in use, the force-sensing instrument includes a rod pusher configured to push a spinal rod into an implant, a mechanical housing including a pair of half nuts configured to engage or disengage from the rod pusher and a compression load cell with one or more strain gages configured to accurately measure strain on the load cell, and an electronic housing including a battery recess having metal contacts coupled to a printed circuit board assembly that wirelessly communicates with the surgical robotic and navigation system;
- and
- a battery cartridge receivable in the battery recess to power the force-sensing instrument.
A smart instrument system for correcting a spinal deformity comprising:
- a surgical robotic and navigation system having an on-board computer with software executed by one or more processing units:
- a force-sensing instrument including two pivotable arms connected by a hinge with distal tips configured to engage the spine, a navigation array with reflective markers for instrument tracking by the surgical robotic and navigation system, an electronic housing containing a printed circuit board assembly configured to wirelessly transmit signals, and a stop mechanism with a reflective marker, wherein the force-sensing instrument is configured to measure strain data in real-time to measure spine stiffness between different levels of the spine and track the positions of the stop mechanism and the instrument during use;
- and
- a battery cartridge receivable in the electronic housing of the force-sensing instrument to power the force-sensing instrument.
