| Usage methods (Surgical techniques) |
| OSTEOTRANS™ System
may basically be used in the same way as metallic osteosynthesis
device, but, as it's mechanical strength is inferior to metallic
devices, caution should be exercised to avoid receiving unreasonable
force. It is advisable to use the special Takiron surgical instruments
(drill bit, tap, screwdriver, and countersink) that match the type
and size of the product. Screws cannot be self-tapped, so after
drilling and cleaning/suctioning, ensure that the screw is threaded
into the drilled hole of the bone using a tap. Insert the screw
only after thoroughly cleaning out the hole. To avoid screw head
damage, insert the screw with the screwdriver while applying with
downward axial-loading. |
| 1 |
Drilling: Drill a hole
of suitable depth with a custom-made drill bit after repositioning
and temporarily fixating the bone fragments. |
| 2 |
Cleaning/suction: Use
suction to remove bone debris from the hole. |
| 3 |
Tapping: Tap a screw
into the drilled hole to a suitable depth using a custom-made tap. |
| 4 |
Cleaning/suction: Use
suction to remove bone debris from the hole after inserting the
screw. |
| 5 |
Insertion (fixation):
Carefully insert the screw with a custom-made screwdriver to fixate
the bone fragments. |
| |
* Use a countersink
when burying the head of the screw into the bone. |
