Method for producing a branch and surgical instrument comprising a tool having a branch
A branch is produced by means of an additive 3D production process for producing a metal part, which comprises at least two parts, namely a support section and a functional section. The metal part is a single-pieced part, in which the support section and the functional section are seamlessly interconnected by means of corresponding connecting webs. After the material is applied, the connecting webs are removed.
1. A method for producing a branch for a surgical instrument, the method comprising:
forming a support piece, at least one electrode and at least one connecting web as a one-piece metal part in an additive production process, the support piece being configured to provide structural support for the branch and being interconnected with the at least one electrode via the at least one connecting web, the support piece, the at least one electrode and the at least one connecting web each comprising a first material;
encapsulating the metal part with a second material; and
removing the at least one connecting web.
2. The method of claim 1 , wherein the one-piece metal part is provided by means of selective laser melting of metal powder.
3. The method of claim 1 , wherein the encapsulating step comprises leaving at least one surface region of the at least one electrode exposed.
4. The method of claim 3 , wherein the support piece and the at least one electrode, in combination with one another, form a gap, wherein at least one holding structure is formed on the at least one electrode, wherein said at least one holding structure does not touch the support piece.
