Definitions

  • the present invention relates to a vertical drilling guide device and a vertical drilling device used in bone conduction implant surgery.
  • the bone conduction implant is a medical device that transmits sound directly to the inner ear through the bone without passing through the outer and middle ear.
  • the bone conduction implant system consists of an implant (Bone Conduction Implant-BCI) and an external device (sound processor).
  • the bone conduction implant system converts the sound captured by the sound processor, an external device, into an electrical signal, and transmits the electrical signal converted from the internal device to the coil of the internal implant inserted into the subcutaneous layer. It works on the principle that sound energy delivered to the inner ear is converted into a nerve signal and transmitted to the auditory nerve for listening.
  • Internal device implant surgery involves injecting a local anesthetic into the surgical site, making a C-shaped incision in the skin for insertion, drilling with a guide drill using a 3mm drill bit, removing the drill bit and drilling to a depth of 4mm Step, placing the implant perpendicular to the bone surface, fixing the implant by tightening, fixing the bone bed indicator to the implant, rotating the bone bed indicator to measure flatness Step, if there is a protruding part, grinding and removing the soft tissue and bone, fixing the implant magnet to the implant, and sealing the surgical site.
  • the implant fixing the implant magnet is inserted vertically, and the surgical site is removed by flat grinding so that the implant magnet does not touch the surface of the insert or too far apart. It is important to maintain and place it. Nevertheless, since the vertical fixation of the implant is made depending on the operator's vision through the upper vertical chim rod of the drill, there is a problem that the accuracy may be lowered. As such, in bone conduction implant surgery, implants used in the dental field such as Republic of Korea Patent Registration No. 10-1763763 despite the fact that vertical fixation of the implant, which is a premise for the implantation process so that the magnet is spaced apart from the skin at regular intervals, is relatively more important.
