  • The BCI Sizer Kit is sent in a sterile package.

  • It contains the Coil-Sizer,

  • the Flat-Transducer-Sizer,

  • the Depth Gauge and the Depth Gauge Handle.

  • The templates are used during Bonebridge surgery.

  • The Flat-Transducer-Sizer and the Coil-Sizer

  • are connected as shown.

  • By using the assembled Sizers,

  • the position of the implant on the skin is determined

  • before the incision is made.

  • The Depth-Gauge-Handle is assembled with the Depth-Gauge

  • to provide easier handling.

  • Press the lower part of the handle together

  • to assemble or disassemble

  • the Depth-Gauge-Handle and the Depth-Gauge.

  • With these templates

  • the position of the BC-FMT is marked on the skull.

  • The Depth-Gauge assembly is put together

  • by placing the Flat-Transducer-Sizer over the Depth-Gauge.

  • It is then used

  • to determine the size and drill depth of the bone bed for the BC-FMT.

  • A decision can then be made as to whether any BCI Lifts are used

  • and if so, which size.

  • For example, if two lines are visible,

  • the 2mm BCI Lifts should be used.

  • The Bonebridge drill bit is supplied in the BCI implant kit.

  • With it the fixation holes are drilled through the Flat-Transducer-Sizer.

  • Once the holes are drilled,

  • the 2mm BCI Lifts are pushed onto the wings of the Bonebridge FMT.

  • With the appropriate screw lengths,

  • the Bonebridge is then screwed into the bone.

  • Initially, they are screwed lightly into the fixation holes.

  • With the torque wrench, the screws are secured firmly.

  • A force of 10 - 20 Ncm is enough to ensure a tight fixation.

  • Depending on how many lines are seen on the depth gauge assembly,

  • the corresponding BCI Lifts are used.

  • For example, if four lines are visible,

  • the 4mm BCI Lifts should be used.

  • The package consists of 2 BCI Lifts,

  • along with two standard screws and one emergency screw,

  • all 10mm in length.

  • The next package available consists of both the 3 and 2mm BCI Lifts

  • along with the corresponding screws being 8mm in length.

  • The 3mm Lifts are used when three lines are visible

  • and the 2mm Lifts when two lines are visible.

  • The 1mm BCI Lifts are used when one line is visible.

  • The package only consists of 2 BCI Lifts

  • as the screws from the Bonebridge implant kit should be used.

  • If there is no line visible,

  • the Bonebridge should be implanted without the use of BCI Lifts.

The BCI Sizer Kit is sent in a sterile package.
