Abstract
A device for determining the required length of a middle ear prosthesis, having a disk-shaped base part to which prosthesis mockups or prostheses of different lengths are fastened, which, after being detached from the base part, can be inserted by an applicator into the middle ear of a patient during an operation for length determination purposes, in which the base part is provided with accessories for measuring and/or shaping the middle ear prosthesis to be inserted, so that this provides the operator with an even more simplified handling of prosthesis mockups or prostheses during the operation; no additional separate parts have to be used and instead, the handling means are compactly provided on or integrated into the device itself.
Claims38
A device for determining a required length of a middle ear prosthesis, comprising a disk-shaped base part to which prosthesis mockups or prostheses of different lengths are fastenable, which, after being detached from said base part, are insertable by an applicator into a middle ear of a patient during an operation for length determination purposes, said base part being provided with accessories for a step selected from the group consisting of measuring, shaping, and both of the middle ear prosthesis to be inserted, said accessories including at least one recess provided on a side selected from the group consisting of a top side, a bottom side, and both of said disk-shaped base part, which has an inner diameter that corresponds to an outer diameter of a head plate of the middle ear prosthesis to be inserted.
A device for determining a required length of a middle ear prosthesis, comprising a disk-shaped base part to which prosthesis mockups or prostheses of different lengths are fastenable, after being detached from said base part, are insertable by an applicator into a middle ear of a patient during an operation for length determining purposes, said base part being provided with accessories for a step selected from the group consisting of measuring, shaping, and both of the middle ear prosthesis to be inserted, said accessories including at least one conical protrusion that protrudes from one side of said base part and used to widen an inner diameter of a bell which is mounted under a head plate of the middle ear prosthesis and used to attach the middle ear prosthesis to stapes of the middle ear.
A device for determining a required length of a middle ear prosthesis, comprising a disk-shaped base part to which prosthesis mockups or prostheses of different lengths are fastenable, which after being detached from said base part are insertable by an applicator into a middle ear of a patient during an operation for length determination purposes, said base part being provided with accessories for a step selected from the group consisting of measuring, shaping and both of the middle ear prosthesis to be inserted, said accessories including at least one hollow in said base part, which is configured for accommodating a cartilage or facia disk that serves as an insert between the middle ear prosthesis and an eardrum in order to mechanically protect the latter.
