Abstract
A medical instrument and method for producing a medical instrument with at least one instrument body part made from an instrument body part blank by forming. The at least one instrument body part has at least one deburring face formed by milling. The at least one deburring face includes one or more portions. Each portion extends perpendicularly to a machining plane. A normal to the machining plane defines a deburring longitudinal axis.
Claims15
A medical instrument with at least one instrument body part, wherein the at least one instrument body part is made from an instrument body part blank by forming, wherein the at least one instrument body part has at least one deburring face formed by milling, wherein the at least one deburring face comprises one or more portions, wherein each portion of the at least one deburring face extends perpendicularly to a machining plane, wherein a normal to the machining plane defines a deburring longitudinal axis, and wherein the at least one deburring face extends in parallel to the deburring longitudinal axis, wherein the medical instrument forms scissors, a plier, a needle holder or a clamp, and comprises two instrument body parts, wherein the two instrument body parts are mounted on one another so as to be pivotable about a pivot axis, and wherein the pivot axis defines the deburring longitudinal axis.
A method for producing a medical instrument that comprises a first instrument body part and a second instrument body part, the method comprising the steps of reshaping an instrument body part blank and removing burrs created during forming, wherein the burrs are removed by milling, wherein the first instrument body part is held during milling, wherein a milling tool is rotated about a deburring longitudinal axis for removing the burrs, and the milling tool is moved in a machining plane for creating at least one deburring face, a normal of the at least one deburring face defining the deburring longitudinal axis, without changing an alignment of the deburring longitudinal axis relative to the machining plane, wherein a joint bore having a bore longitudinal axis is formed on each of the first instrument body part and the second instrument body part, said bore longitudinal axis extending in parallel or substantially in parallel to the deburring longitudinal axis, wherein the first instrument body part is coupled to the second instrument body part so as to be pivotable relative to the second instrument body part about the bore longitudinal axis, and wherein the medical instrument is one of scissors, a plier, a needle holder or a clamp.
