No
The summary describes a mechanical device (self-drilling screws) and does not mention any software, algorithms, or data processing that would indicate the use of AI/ML.
Yes
The device is used for internal fixation to aid in the stabilization and fixation of bones, which is a therapeutic purpose.
No
The device described is an internal fixation device (self-drilling screws) used for stabilization and fixation during surgical procedures. Its purpose is therapeutic/interventional, not to diagnose a medical condition.
No
The device description clearly describes physical hardware components (self-drilling screws) and their intended use in surgical procedures, indicating it is a hardware medical device, not software-only.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
- Device Description: The provided description clearly states that this device is an "Internal fixation device" consisting of "self drilling screws" used for "stabilization and fixation of oral micinal 'itsanon' do recess' to 'all bones of the hand, feet, wrist, ankles, fingers and toes, Craino-maximonomics, osteotomies, revision procedures, joint fusion and reconstructive procedures."
- Intended Use: The intended use is to aid surgeons in physically stabilizing and fixing bones. This is a surgical procedure performed directly on the patient's body, not an analysis of a specimen outside the body.
Therefore, based on the provided information, this device is a surgical implant/instrument, not an In Vitro Diagnostic device.

§ 888.3040 Smooth or threaded metallic bone fixation fastener.
(a)
Identification. A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.

Sterility Information:
The Lorenz Self Drilling Screws will be marketed as non-sterile, single use devices. Steam Sterilization recommendations are included in the package insert and can be seen in Attachment I.
Substantial Equivalence:
Walter Lorenz considers the Lorenz Self Drilling Screws equivalent to Synthes 1.3MM Self C Drilling Screw (K983485), Osteomed Corp. Auto-Drive Bone Screw (K974785), and KLS TAB 3 includes a substantial Martin L.P. Centre-Drive Drill Free Screw (K971297). equivalence comparison table to competitive devices. TAB 4 includes sales information and/or Premarket clearance (510K) for Synthes, Osteomed Corp. and KLS Martin L.P.
Possible risks:
-
- Poor bone formation, Osteoporosis, Osteolysis, Osteomyelitis, inhibited revascularization, or infection can cause loosening of the device.
-
- Nonunion or delayed union which may lead to breakage of the implant.
-
- Migration, bending, fracture or loosening of the implant
-
- Metal sensitivity, or allergic reaction to a foreign body.
-
- Decrease in bone density due to stress shielding.
