Subcutaneous, intramuscular bearing for a rigid transcutaneous implant
First Claim
1. A subcutaneous, intramuscular bearing for a rigid transcutaneous implant (2), which can be anchored intracorporally in a bone stump, comprising:
- an intermediate piece (3) between the implant (2) and an extracorporal coupling that can be coupled to the implant a rigid bushing (5) tightly connected to the intermediate piece (3), such that between a wall of the bushing (5) and the intermediate piece (3) a closed annular space (6) is formed in an intracorporal direction to receive the extracorporal coupling, an open-meshed, three-dimensional lattice structure (8) on an outer wall of the bushing (5) and a distal region of the outer wall having a width B which is free of the three-dimensional lattice structure, and a spring ring (9), insertable in the annular space (6) from its distal end, moved there with a telescoping motion, and locked under exertion of a spring effect of the spring ring (9).

Abstract
A subcutaneous, intramuscular bearing (1) for a rigid transcutaneous implant (2) is provided, for anchoring intracorporally in a bone stump and having an intermediate piece (3) between the implant (2) and an extracorporal coupling for coupling on the implant. A rigid bushing (5) is tightly connected to the intermediate piece (3), such that between the wall of the bushing (5) and the intermediate piece (3) an annular space (6) is formed, which is closed in the intracorporal direction, for receiving and setting the extracorporal coupling. The outer wall of the bushing (5) has an open-meshed, three-dimensional lattice structure (8) and a lattice-free distal region having a width B. A spring ring (9) is set in the annular space (6) from the distal end, moved with a telescoping motion, and locked under exertion of its spring effect.

9. A subcutaneous, intramuscular bearing for a rigid transcutaneous implant (102), which can be anchored intracorporally in a bone stump, comprising:
-
an intermediate piece (103) between the implant (102) and an extracorporal coupling (107) that can be coupled to the implant, a rigid bushing (105) tightly connected to the intermediate piece (103) with a coupling element (106), which is closed in an intracorporal direction and to which the extracorporal coupling (107) can be coupled, an open-meshed, three-dimensional lattice structure (108) on an outer wall of the bushing (105) and a distal region of the outer wall having a width B which is free of the three-dimensional lattice structure, an activatable device for applying bioactive material, provided in a region where the implant emerges from the leg stump, and a spring ring (109), insertable in the coupling element (106) from its distal end, moved there with a telescoping motion, and locked under exertion of a spring effect of the spring ring (109). - View Dependent Claims (10, 11, 12, 13, 14, 15)
