Introduction Legend Important warnings appear in orange Tips, tricks and important information appear in blue Indications, contraindications, intended use and training The Smith & Nephew TRIGEN™ SURESHOT™ Distal Targeting System is intended to be an intraoperative image-guided localization system. It is a computer-assisted orthopaedic surgery tool to aid the surgeon with drill positioning for screws during intramedullary nail implantation. It provides information to the surgeon that is used to place surgical instruments during surgery utilizing intraoperatively obtained electromagnetic tracking data. The Smith & Nephew TRIGEN SURESHOT Targeting System V2.1 is indicated for long bone fractures treated with intramedullary nails in which the use of stereotactic surgery may be appropriate. An example of a surgical procedure includes but is not limited to locating and drilling the distal holes in an intramedullary nail. Contraindications The screw targeting software application for this system is contraindicated for all IM nails other than Smith & Nephew TRIGEN META-NAIL, TAN, FAN, Humeral, Pediatric and Adolescent nails. Do not operate the TRIGEN SURESHOT Targeter within 200mm of an installed pacemaker. The magnetic field produced by the Targeter may interfere with the operation of the pacemaker. Intended use The TRIGEN SURESHOT Distal Targeting System is only designed for use with the indicated implants and instruments. Implants and instruments must be used in accordance with the instructions, as described in this manual and/or in the non-navigated surgical procedure. Training Only trained operators are allowed to use the TRIGEN SURESHOT Distal Targeting System. The various operating instructions must be fully read and understood as part of the training. If any part of the instructions is not clear, please contact your local representative. Plausibility check As with all technical equipment, malfunctions may occur due to improper use or, more rarely, technical failure. To reduce the risks involved with such technical malfunction the operation can be completed using manually controlled instruments, providing the malfunction is detected without delay. It is, therefore, important to check the plausibility of the steps, as indicated by the system, and to carry out verification of the software targeting, particularly when using the system for the first time. Should there be any doubt regarding correct functioning, the targeting should be verified or a switch made to a traditional X-Ray technique. 2

Place the IM nail with inserted probe directly beside the patient’s limb. Position the Targeter over the locking holes and verify the accuracy on the Trauma Interface.
Optional – Field accuracy check An optional field accuracy check can be performed at this point using the instructions in the Maintenance section.
Note This step should be performed at least once a year to ensure that the device is working properly. 13
Surgical procedure – Distal Targeting Note When the Targeter is out of the preferred range or there is metal or electrical interference, the green and red Targeter circles on the navigation screen may become unstable and/or a warning message will be displayed. If the interference is excessive, the IM nail image on the navigation screen will disappear. If interference cannot be avoided, a standard X-Ray technique must be used. Note All tool cables should be uncoiled completely and any excess cables should be kept out of the Targeter measurement volume.
Probe and set stop insertion Following the removal of the Ball Tip Guide Rod, insert the probe and set stop into the IM nail as described in the locking hole accuracy check on the previous page.
Skin incision Position the serrated tip of the drill sleeve (represented by the green circle) over the desired locking hole and make the initial incision.
Note Reference the warnings and tips in the locking hole accuracy check on the previous page.
Tip If performing this procedure using any of the TriGEN™ femoral antegrade nails (TAN™/FAN/ Pediatric/Adolescent), the Anteversion Locking Guide (7169-2816) should be used along with a 4.0mm Drill Sleeve/Drill Bit to keep the IM nail from rotating.
Targeting the locking hole With the appropriate length TRIGEN SURESHOT™ 4.0mm Drill Bit (7169-2810 or 7169-2811) or the TRIGEN SURESHOT Humeral AO Drill Bit (7169-1155) inserted into the Targeter, insert the tip of the drill sleeve (represented by the green circle) through the incision and down to bone. Critical Verify there are no other metal objects (including metal triangles) in the field. Metal interference will cause the system to be inaccurate.
14
Adjust the trajectory of the Targeter (represented by the red circle) until both the green and red circles are concentric and drill through to the far cortex. Note The green ring must be fully within the hole of the IM nail displayed on the navigation screen to ensure accurate drilling.
The accuracy may be verified using the C-arm.
Note The standard TriGEN™ drill bits are made from magnetic stainless steel that will cause interference with the system and cannot be used. Be sure to use the gold non-magnetic TRIGEN SURESHOT™ drill bit or long gold non-magnetic drill bit.
Length measurement Before drilling through the far cortex, measure the length using the calibrations on the TRIGEN SURESHOT 4.0mm Drill Bit or the TRIGEN SURESHOT Humeral AO Drill Bit (7169-1155).
Tip After measuring the length on the drill bit prior to drilling the far cortex, add the appropriate screw length in order to account for the thickness of the far cortex. Ensure the Targeter and the sleeve are pushed against the bone.
Alternatively, the length measurement can be achieved using the standard Screw Length Gauge (7163-1189) through the Targeter after removing the drill sleeve.
Screw insertion Using the TRIGEN SURESHOT Hexdriver (7169-2809 or 7169-1153), the screw may be inserted using the Targeter.
Tip If the Targeter is placed too close to the bone, the image of the IM Nail on the display might disappear. Note The standard TriGEN Hexdrivers are made from magnetic stainless steel that will cause interference with the system and cannot be used.
15
The depth of the screw can be verified by placing a 9.0mm Gold Drill Sleeve (7163-1152 or 7175-1128) down to bone over the hexdriver. The screw head will be flush with bone when the groove on the hexdriver is even with the end of the 9.0mm Gold Drill Sleeve.
The positioning of the screw may be verified using the C-arm.
16
Navigation screen operation Overview mode When the Targeter is greater than 5cm from the interlocking holes, the navigation screen will display the IM nail in the overview mode. This provides the user with a larger field of view in order to help find the general location of the interlocking holes. Note If the desired hole in the nail is not oriented to be viewed on the screen, then the orientation of the Targeter is not aligned closely enough to that specific hole. Try holding the Targeter generally AP or generally ML to orient the desired view.
Drilling mode When the Targeter is moved within 5cm of the interlocking holes, the navigation screen will display the IM nail in the drilling mode. This provides the user with a smaller field of view that automatically zooms in to the interlocking holes. The white lines displayed on either side of the IM nail can be used for targeting blocking screws. These lines are located 2.5mm from the side of the IM nail for all IM nails 10mm and larger in diameter. These lines are located 2mm from the sides of 8.5mm IM nails.
Drilling mode manual rotation Each IM nail has several predefined views that are automatically selected depending on the position of the Targeter to the IM nail. Depending on the operating environment, these predefined views might not be appropriate and can be manually adjusted. To rotate the view Touch the screen near the outside and “drag” the view in a clockwise or counterclockwise direction. To flip the view Touch the “Menu” button and select “Toggle Back View.” All changes made for a view are temporarily stored for that view until program exit. To reset the view The default view settings can be restored by touching the “Menu” button and selecting “Reset View” or double tapping the center of the screen.
17
Shutting down the system, storage and transport Shutting down the system • Shut down the Trauma Interface by selecting
the “Shut Down” option from the on-screen “Menu” button. • Switch off the main power switch on the rear of
the unit. • Unplug the power supply cable.
Note Shut down the Trauma Interface using the on-screen “Shut Down” option and wait for the system to power down before switching off power or unplugging from main power supply. Note The internal fan of the Trauma Interface runs continuously whenever the rear power switch is in the ON position. Switch power off whenever the unit is not in use.
Storage and transport • Place the Trauma Interface (screen up) in the
transportation case. • Coil the power cord and store in the
transportation case. • Consider the temperature and humidity
range for storage and transportation on the transportation case.
Caution Do not place any objects on top of the screen when the Trauma Interface is stored in the shipping container. Damage to the screen may occur.
18
Maintenance Field accuracy check A field accuracy check procedure should be performed at least once a year or whenever the accuracy of a TRIGEN™ SURESHOT™ probe or TRIGEN SURESHOT Targeter needs to be verified. This procedure can also be performed during surgery to verify all components are working correctly prior to their use on a patient. Field accuracy check steps 1 Attach TRIGEN SURESHOT Field Accuracy Gauge
(7169-2808) to TRIGEN SURESHOT Targeter. The knob on the Field Accuracy Gauge should be hand tightened only.
2 Attach the META Set Stop (7169-2806) to the end
of the Field Accuracy Gauge, insert a TRIGEN SURESHOT probe into the set stop and set the depth to the “REF” mark on the probe body.
3 From the software “Menu” button, select “Field
Check” option.
