The invention relates to a joint implant component (1, 1'; 101; 201) for administering a pharmaceutical product, said component having an implant shaft (10, 10'; 110; 210), a joint section (20, 20'; 120; 220) located at the proximal end of the implant shaft, a flush supply opening (3, 3'; 103; 203), and a backflush opening (4, 4'; 104; 204). At least one shaft flush channel (11, 11'; 111; 211) and one shaft backflush channel (12, 12'; 112; 212) extend along the implant shaft inside same. The shaft flush channel is connected to the outside of the implant shaft via shaft flush holes (13, 13'; 112; 213) for dispensing the pharmaceutical product and the shaft backflush channel is connected to the outside of the implant shaft via at least one shaft backflush hole (14, 14'; 114; 214) for receiving the dispensed pharmaceutical product. The flush supply opening is fluidically connected to the proximal end of the shaft flush channel and the backflush opening is fluidically connected to the proximal end of the shaft backflush channel. The invention also relates to a joint implant comprising two such joint implant components which are connected to one another by joint surface parts (30, 40; 230) and can be pivoted relative to one another. |
