Abstract
A surgical handheld devices are essentially made up of a device body or main body and of a tubular shaft. In the production of known surgical devices, the tubular shafts are welded to the device bodies. A large number of very complex work steps are necessary for this purpose. On account of the high quality demands placed on surgical handheld devices in respect of mechanical stability and sterility, the weld seam has to meet the most stringent requirements. The invention makes available a method for producing a surgical handheld device, which can be used particularly easily and reliably. This is achieved by the fact that at least one device body and at least one tubular shaft of a surgical handheld device are connected to each other with form-fit engagement by hydroforming.
