Abstract
The present disclosure relates to a device that can guide perpendicular drilling and simultaneously measure flatness of an insertion surface through a locking protrusion by rotating the device in bone conduction implantation. According to the present disclosure, it is possible to measure flatness and guide perpendicular boring with a constant force even without using a separate flatness measurer in surgery. Further, it is also possible to guide drilling using a spacer having a smaller diameter by using an assistant guide member.
Claims19
A device for guiding perpendicular drilling and measuring flatness of a bone conduction implant, wherein the device is configured to be supported on a bore surface of the bone conduction implant, has a through-hole formed at a center perpendicular to the bore surface of the bone conduction implant, and has a circular bottom,
- wherein a locking protrusion is formed at a portion of an outer surface of the bottom.
A device for guiding perpendicular drilling and measuring flatness of a bone conduction implant, the device comprising a bottom ring having a locking protrusion formed at a portion of an outer surface, a top ring having a through-hole for guiding perpendicular drilling, and connectors connecting the bottom ring and the top ring.
