Fräser zum Bearbeiten des Sitzes für eine HüftgelenkpfanneMilling cutter for processing the seat for an acetabular cup

Zum Auslräsen des Sitzes für eine Hüftgelenkpfanne, vorzugsweise aus Kunststoff, zur Aufnahme einer Hüftgelenkprothese werden kugelförmige oder etwa halbkugelförmige Fräser geeigneter Größe verwendet.For milling out the seat for an acetabular cup, preferably made of plastic, to accommodate a hip joint prosthesis are spherical or approximately hemispherical cutters of suitable size are used.

Die Fräser werden von Hand mittels Handkurbel oder durch einen Elektro- oder Druckluftmotor angetrieben, und zwar mit Rücksicht auf das zu bearbeitende Knochenmaterial und den großen Durchlass= eer des Fräsers von cirka 50 mm, mit niedriger Drehzahl. Bekannte Fräser dieser Art haben den Nachteil, daß beim Fräsen de« Sitzes für die Hüftgelenkpfanne ein unangenehmes Rattern auftritt, das für den Operationsablauf unerwünscht und für den Chirurgen unangenehm und störend ist; »nch leidet darunter die Präzision der Arbeit.The milling cutters are driven by hand with a hand crank or by an electric or compressed air motor, with due consideration on the bone material to be processed and the large opening of the milling cutter of approx. 50 mm, with low speed. Acquaintance Cutters of this type have the disadvantage that an unpleasant rattling occurs when milling the «seat for the acetabulum, which for the operational sequence undesirable and uncomfortable for the surgeon and is disruptive; “The precision of the work suffers as a result.

Erfindungsgemäfi wird dieser Nachteil dadurch beseitigt, daß ein halbkugel- bis etwa vollkugelförmiger Rotationskörper - vorzugsweise aus Stahl - von geeigneter Größe, an seiner Oberfläche mit Raapelhleben, ähnlich wie bei einer Helzraepsl, versehen wird und, daß etwa parallel zu seiner Rotationsachse mindestens eine Aussparung sum Abführen der Späne vorgesehen ist.According to the invention, this disadvantage is eliminated in that a hemispherical to approximately fully spherical body of revolution - preferably made of steel - of suitable size, on its surface with Raapelhleben, similar to a Helzraepsl, and that about At least one recess is provided parallel to its axis of rotation for removing the chips.

Abb. 1 zeigt einen solchen Fräser mit etwa 50 mm Durchmesser und einigen Raspelhieben auf einen Antriebsechaft aufgeschraubt, Fig. 1 shows such a milling cutter with a diameter of about 50 mm and a few rasp cuts screwed onto a drive shaft,

Abb. 2 zeigt die Draufsicht fsuf den Fräser, ohne Raspelhiebe,Fig. 2 shows the top view of the cutter, without rasp cuts,

Mit (1) ist der Rotationskörper bezeichnet, auf dessen Oberfläche die Raspelhiebe (2) mehr oder weniger eng verteilt sind. Der Rotationskörper sitzt auf der Antriebswelle (3) und weist mindestens eine Aussparung (4) zum Abführen der Späne auf.With (1) the rotation body is referred to, on the surface of which Rasp cuts (2) are more or less closely spaced. The rotating body sits on the drive shaft (3) and has at least one recess (4) to discharge the chips.
