The summary describes a mechanical targeting system and clinical trials focused on procedure time, with no mention of AI, ML, image processing, or data sets typically associated with AI/ML development.
No
The device is used to assist in the placement of screws in intramedullary nails, which is a procedural aid, not a diagnostic or therapeutic function itself.
No
The device is described as a "targeting system" used for placing screws in intramedullary nails, aiming to reduce the time required for this procedure. It does not provide information about a patient's health status or condition.
No
The device description explicitly mentions "reusable accessory adapter components" and a "QuickLock Probe" and "QuickLock Guide," which are physical hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use describes a system used during a surgical procedure to assist with placing screws in bones. This is an in vivo (within a living organism) application, not an in vitro (outside of a living organism) diagnostic test.
- Device Description (Not Found): While the description is missing, the intended use clearly points to a surgical tool.
- Mentions image processing, AI, DNN, or ML (Not Found): These are often associated with IVD devices that analyze images or data for diagnostic purposes.
- Input Imaging Modality: The use of C-arm image intensifiers generating x-rays is consistent with surgical imaging, not typical IVD testing.
- Anatomical Site (Not Found): While not explicitly stated, the use with intramedullary nails implies a skeletal anatomical site, which is consistent with surgical intervention.
- Intended User / Care Setting: Surgeons in a surgical setting are the intended users, not laboratory personnel typically associated with IVD testing.
- Performance Studies: The performance studies focus on the time required for a surgical procedure (distal targeting), not on the accuracy or reliability of a diagnostic test.
- Key Metrics: The key metric is "Time Required for Distal Targeting," which is a measure of surgical efficiency, not diagnostic performance.
In summary, the QuickLock Orthopaedic Targeting System is a surgical tool designed to aid in a specific surgical procedure. It does not perform any diagnostic testing on samples taken from the body, which is the defining characteristic of an IVD.

Radiation Exposure
Ionizing electromagnetic x-rays are generated by the C-arm image intensifier. Concern for minimizing the risk of x-ray exposure to surgeons and patients is a prominant factor in the freehand technique currently employed by the predicate devices.
The low-energy, 25 KHz sinusoidal, nonionizing electromagnetic field generated by the probe coils is an nonsignificant radiation hazard* and produces negligible temperature rise of the probe surface.
- Opinion of Howard Bassen, Head, Electro-Physics Branch, FDA Office of Science and Technology, telephone conversation July 29, 1994, in which Mr. Bassen confirmed that FDA does not impose standards for electromagnetic radiation unless the device causes heating of body tissue.
Electric Shock
The C-arm image intensifier is an electronic device. It can contact operating room personnel, surgical apparatus in contact with the patient, or the patient directly, because during the distal targeting procedure it is close to the surgical field and is moved about by a technician to align the x-ray beam with the axis of the target hole. Operating room personnel and patients must, therefore, be protected from electric shock by Carm compliance with safety standards for electronic medical devices.
The display, probe and guide come into contact with operating room personnel and patients, and are to be certified to UL Standard 544, 2d Edition. The display is in a sturdy, grounded, metal enclosure with 115 VRMS at 60 Hz input power, + /-12 VDC and +5 VDC internal power. Line power is limited by a 250V, 3AG UL 198.6, 2A, FAST type fuse. The AC to DC power supply and electroluminescent display are medical-grade components. Separation and insulation of internal display components prevent shock and fire hazardous conditions. Risk of shock by contact with the probe and guide is eliminated by low voltage levels, isolation, insulation and grounding. The probe coil voltage is below 12 VRMS with polyimide tube insulation breakddown above 1200 V. Probe coils are isolated from the display unit by transformer coupling, and the metal outer surface is grounded through the probe cable shield. Guide components reach voltages far less than 12 VRMS. The guide body is nonconductive, insulated by encapsulation of internal components, and is grounded through a wire in the guide cable.

Effectiveness
Predicate Devices
QuickLock System
Intended Use
Locate incisions, guide bone drilling, and guide insertion of interlocking screws in the distal targeting procedure of intramedullary nailing.
Same as for predicate devices
Skill and Experience Required
Users must strive to hold the drill in alignment after short x-ray exposures that provide only intermittent visual control. This requires considerable skill and experience. Surgeons who infrequently perform the procedure fall out of practice and are markedly less effective.
Users have continuous visual control so the task is easier and less training, skill and experience are required. Surgeons learn the technique after a few minutes of training. Proficiency is retained without frequent performance of the procedure.
Accuracy of Visual Cues
Adjustment of C-arm position to align the x-ray beam with target holes depends on visual perception of distal holes as true circles on the image intensifier screen. Subjective judgement limits reliable accuracy of this alignment. Operator skill strongly affects accuracy of drilling between visual snapshots.
The probe and guide are aligned mechanically with target holes during the calibration process, which electronically offsets errors for each procedure. Drilling accuracy is enhanced by the high visual sensitivity of dot and cross-hair sight adjustments and the continuous display of visual sighting information.
Operator Comfort
The need to minimize exposure to x-ray radiation hampers the freehand technique used with the predicate devices. Surgeons work in awkward positions, reaching from the side to avoid the xray beam.
Because there is no need to stay out of an x-ray beam, surgeons can stand, hold the guide, and drill in a comfortable position.
Quality of Drilled Holes
Holes started out of alignment must be elongated to pass through the nail and both cortices. This reduces the holding strength and endurance of bone screws and compromises the objective of nail interlocking.
Accurate alignment throughout the drilling process ensures correct hole size and shape, for maximum screw holding strength and endurance.
Nicking of Intramedullary Nails
Drills often strike the edges of target holes, leaving nicks that can cause stress concentration in the nail material and lead to premature nail breakage due to fatigue fracture.
Improved accuracy reduces the occurance of drill strikes and the resultant risk of induced nail fatigue failure.
