Screw tower and rod reduction tool

Abstract

A system includes a screw tower, an instrument, and a housing. The instrument includes a driver shaft extendable longitudinally through the screw tower, and a threaded sleeve mounted on a proximal portion of the driver shaft. The housing includes one or more retention members coupleable to the screw tower, and a threaded button threadably coupleable to the threaded sleeve. The threaded sleeve is rotatable about a longitudinal axis to urge the driver shaft longitudinally relative to the screw tower.

What is claimed is: 
     
         1 . A tracking system for tracking one or more objects during a surgical procedure, said system comprising:
 a computer including a processor, memory, an input interface, and an output interface;   a display in electronic communication with the output interface;   a first screw tower positioned at a first location on a patient during the surgical procedure;   a position sensor including a camera in electronic communication with the input interface of the computer;   one or more first tracking markers disposed on the first screw tower,   wherein the position sensor is configured to detect the one or more first tracking markers to determine position sensor data of the one or more first tracking makers;   and the processor is configured to receive the position sensor data and present the position of the first screw tower, via the display, in relation to an image of an anatomical structure of the patient.   
     
     
         2 . The system of  claim 1 , further comprising:
 a second screw tower positioned at a second location on the patient; and   one or more second tracking markers disposed on the second screw tower.   
     
     
         3 . The system of  claim 2 , wherein the camera is an infrared camera configured to detect light from the one or more first tracking markers and the one or more second tracking markers. 
     
     
         4 . The system of  claim 3 , wherein the one or more first tracking markers and the one or more second tracking markers are passive tracking markers. 
     
     
         5 . The system of  claim 4 , wherein the one or more first tracking markers is a first cluster of stripes and the one or more second tracking markers is a second cluster of stripes, wherein the first cluster of stripes has an inter-stripe spacing different from the second cluster of stripes. 
     
     
         6 . The system of  claim 4 , wherein the one or more first tracking markers is a first cluster of stripes and the one or more second tracking markers is a second cluster of stripes, wherein the first cluster of stripes has a stripe thickness different from the second cluster of stripes. 
     
     
         7 . The system of  claim 1 , further comprising a robot trackable by the position sensor. 
     
     
         8 . The system of  claim 7 , further comprising a surgical tool trackable by the position sensor. 
     
     
         9 . The system of  claim 8 , further comprising a patient tracking device secured to the patient that is trackable by the position sensor. 
     
     
         10 . The system of  claim 2 , wherein the one or more first tracking markers and the one or more second tracking markers are unique identifiers trackable in three dimensions. 
     
     
         11 . A tracking system for tracking one or more objects during a surgical procedure, said system comprising:
 a computer;   a first object positioned at a first location on a patient during the surgical procedure;   a position sensor including a camera in electronic communication with the computer;   one or more first tracking markers disposed on the first object,   wherein the position sensor is configured to detect the one or more first tracking markers to determine position sensor data of the one or more first tracking makers and provide the position sensor data to the computer.   
     
     
         12 . The system of  claim 11 , further comprising:
 a second object positioned at a second location on the patient; and   one or more second tracking markers disposed on the second object.   
     
     
         13 . The system of  claim 12 , wherein the camera is an infrared camera configured to detect light from the one or more first tracking markers and the one or more second tracking markers. 
     
     
         14 . The system of  claim 13 , wherein the one or more first tracking markers and the one or more second tracking markers are passive tracking markers. 
     
     
         15 . The system of  claim 14 , wherein the one or more first tracking markers is a first cluster of stripes and the one or more second tracking markers is a second cluster of stripes, wherein the first cluster of stripes has an inter-stripe spacing different from the second cluster of stripes. 
     
     
         16 . The system of  claim 14 , wherein the one or more first tracking markers is a first cluster of stripes and the one or more second tracking markers is a second cluster of stripes, wherein the first cluster of stripes has a stripe thickness different from the second cluster of stripes. 
     
     
         17 . The system of  claim 11 , further comprising a robot trackable by the position sensor. 
     
     
         18 . The system of  claim 17 , further comprising a surgical tool trackable by the position sensor. 
     
     
         19 . The system of  claim 18 , further comprising a patient tracking device secured to the patient that is trackable by the position sensor. 
     
     
         20 . The system of  claim 12 , wherein the one or more first tracking markers and the one or more second tracking markers are unique identifiers trackable in three dimensions.
