Surgical instrument comprising electrode support
A branch of an instrument comprising a metal part, which is embodied in one piece seamlessly, which comprises the electrode support as well as the electrode plate and connection webs. Preferably, this metal part is produced in an additive production method, for example selective laser melting (SLM). The branches are suitable for instruments for open surgery as well as for laparoscopic and flexible endoscopic instruments.
1. An electrosurgical instrument comprising a branch, the branch comprising:
an electrode plate defined by a first edge contour; and
an electrode support defined by a second edge contour,
wherein the electrode plate and electrode support are arranged to define a slit,
wherein an opening of the slit extends between the first and second edge contours,
wherein the electrode plate and the electrode support are connected to one another seamlessly in one piece via a plurality of webs, and
wherein the plurality of webs, the electrode support and the electrode plate are embodied of material with the same composition and structure without any transition.
2. The instrument of claim 1 , wherein the webs are arranged at a distance from the opening of the slit.
3. The instrument of claim 1 , wherein the distance of the webs from the second edge contour of the electrode support is larger than a width of the opening of the slit.
4. The instrument of claim 1 , wherein the webs comprise a round cross section.
5. The instrument of claim 1 , wherein the webs comprise a largest diameter, which is smaller than the width of the opening of the slit.
6. The instrument of claim 1 , wherein the electrode support comprises a bowl-shaped cross section.
7. The instrument of claim 1 , wherein the electrode plate transitions seamlessly into the electrode support at one end.
8. The instrument of claim 1 , wherein the electrode plate is embodied as flat part.
9. The instrument of claim 1 , wherein the electrode plate comprises a profiling.
10. The instrument of claim 1 , wherein the electrode plate comprises a thickness that is smaller than the width of the opening of the slit.
11. The instrument of claim 1 , wherein the electrode support, the webs and the electrode plate are provided in an additive or generative production method from a homogeneous material.
12. The instrument of claim 1 , wherein the slit is filled with a material having a heat conductivity smaller than the heat conductivity of a material of the electrode plate.
13. The instrument of claim 1 , wherein the electrode support is coated with an electrically insulating material.
14. The instrument of claim 1 , wherein the electrode support comprises a through opening for embodying a bearing bore.
15. The instrument of claim 14 , wherein the through opening is lined with an electrically insulating material.
16. The instrument of claim 11 , wherein the additive method is selective laser melting.
