Embodiment Construction

[0121] The following detailed description, taken in conjunction with the accompanying figures, serves as a description of many different structures. The detailed description includes specific details to enable a thorough understanding of various concepts. It will be apparent, however, to one skilled in the art that these concepts may be practiced without these specific details.

[0122] Figure 1AA schematic view of a perforating member 6 for providing a circular cutout according to an embodiment is shown. Perforating member 6 along the direction d shown 1 Move towards the soft tissue 2 of the patient. The punch 6 can be a sterile standard punch. The perforating member 6 can be a disposable standard punch.

[0123] The perforated member 6 has a diameter of 5 mm, such as Figure 1B The width W in 1 shown. However, as an example, the punch may have another diameter such as 4.0 mm. Before the piercing procedure, select the appropriate position P and shaved the skin. Pre...

Abstract

The present invention discloses a method and device for installing an implant of a bone-anchored hearing aid, wherein the drill guide used comprises a cylindrical portion comprising a cylindrical channel extending along its longitudinal axis, said cylindrical channel being adapted to receiving a drill bit to drill the blind hole in the bone; and a flange at a proximal portion of the drill guide extending perpendicular or substantially perpendicular to the longitudinal axis of the cylindrical portion; wherein the drill guide Having a length equal to or greater than the thickness of the soft tissue, and when inserted into the hole, the distal end of the drill guide is adapted to bear against a bone surface interfacing with the soft tissue.

Description

technical field [0001] The present invention generally relates to devices and methods for installing implants. In particular, the present invention relates to devices and methods for installing screws and abutments for implants such as bone-anchored hearing aids, craniofacial prostheses and maxillofacial retention systems. Background technique [0002] Medical implants such as bone-anchored hearing aids are used in the rehabilitation of patients suffering from hearing loss for whom conventional hearing aids are insufficient. A typical bone-anchored hearing aid includes an external hearing aid with a vibration transducer connected by a coupling to a skin-penetrating abutment. The abutments may be interconnected with screw-shaped fixation structures anchored in the skull. The fixation structure may be made of titanium and have flanges to prevent the fixation structure from being pushed through the skull when exposed to a sudden accidental impact. [0003] The abutment penet...
