Abstract
The disclosed embodiments describe a method for producing a bent tubular shaft for a tubular shaft instrument as well as a tubular shaft produced in such manner as well as a tubular shaft instrument with such a bent tubular shaft. The tubular shaft is produced by providing a hollow shaft component and an actuating rod. The actuating rod in this case has at least one bending area in which flexible segments and support segments alternate. The at least one bending area of the actuating rod is provided with a friction-reducing layer before it is inserted into the shaft component in order to create a tubular shaft. The tubular shaft is then bent in an area that corresponds to the at least one bending area of the actuating rod.
