Abstract

A method for producing a medical instrument, includes producing, by cutting material from a semi-finished product, a shaft including a clamping region and at least part of a head including cutting edges; additively generating at least part of the head of the instrument; performing the additively generating with a rotation axis of the instrument aligned vertically; reworking at least part of the head with a subtractive method; and using the subtractive method to perform at least one chosen from sharpening cutting edges and improving concentric running of the instrument.

Claims (11)

1. A method for producing a medical instrument, comprising:

producing, by cutting material from a semi-finished product, a shaft including a clamping region and at least part of a head including cutting edges,

additively generating at least part of the head of the instrument;

performing the additively generating with a rotation axis of the instrument aligned vertically;

reworking at least part of the head with a subtractive method;

using the subtractive method to perform at least one chosen from sharpening cutting edges and improving concentric running of the instrument.

2. The method as claimed in claim 1 , wherein the additively generating is performed using a selective laser application method, a selective laser sintering method or an electron beam welding method.

3. The method as claimed in claim 1 , wherein at least the additively generated part of the instrument is made of steel, ceramic, hard metal, titanium, titanium alloy or plastic.

4. The method as claimed in claim 1 , wherein the subtractive method is at least one chosen from a laser ablation method and a cutting method.

5. The method as claimed in claim 1 , wherein the instrument is at least one chosen from a dental drill, a milling cutter, a grinding instrument, a sonic tip and a saw blade.

6. The method as claimed in claim 1 , wherein the instrument is a dental instrument.
