Medical apparatus, and surgical method

摘要

An apparatus for automated implantation of an implant or for an automated augmentation process of hard tissue and/or hard tissue replacement material using a sheath element is provided. The apparatus comprises a casing, a converter operable to generate mechanical vibrations the converter inside the casing and displaceable in a longitudinal direction relative to the casing, and a sonotrode coupled to an output location of the converter. A shaft portion with a retention structure is rotationally coupled to the casing and is equipped for cooperating with a rotationally asymmetric element of the sheath element to rotationally couple the casing to the sheath element. An axial coupling is equipped for locking the casing to the sheath element. The shaft portion, the axial coupling and the sonotrode are mutually arranged so that the a distal end of the sonotrode may be introduced into a longitudinal opening of the sheath element.

1. An apparatus for automated implantation of an implant or for an automated augmentation process of hard tissue and/or hard tissue replacement material using a sheath element, the apparatus comprising:
a casing, a converter operable to generate mechanical vibrations the converter being mounted inside the casing to be displaceable in a longitudinal direction relative to the casing, a sonotrode coupled to an output location of the converter, a shaft portion with a retention structure that is rotationally coupled to the casing and is equipped for cooperating with a rotationally asymmetric element of the sheath element to rotationally couple the casing to the sheath element, and an axial coupling locking the casing to the sheath element, wherein the shaft portion, the axial coupling and the sonotrode are mutually arranged so that the a distal end of the sonotrode may be introduced into a longitudinal opening of the sheath element by a displacement of the converter relative to the casing when the sheath element is locked to the casing.
