Fastening device, implant device, locking method, and operation method
View Patent ↗The invention relates to a fastening device for implant device, the fastening device comprising at least two fastening sections, where a first fastening section is arranged with a through hole, a second fastening section is arranged with a protruding part, and where said protruding part is in place in said through hole in a fastening device locking state, where the protruding part on the second fastening section is arranged with a through channel having an inlet and an outlet, said through channel being arranged to receive an implant device feed member, said inlet and outlet being accessible from the exterior of the fastening device in said fastening device locking state, wherein the first fastening section is securely locked to the second fastening section when, in said fastening device locking state, said implant device feed member is in place in the through channel and protrudes from both the inlet and the outlet of said through channel. The invention further relates to an implant device comprising a fastening device, and a method for securely locking a first fastening section of a fastening device for an implant device to a second section of a fastening device for an implant device.
1. A fastening device for implant device, the fastening device comprising at least two fastening sections, where a first fastening section is arranged with a through hole, a second fastening section is arranged with a protruding part, and where said protruding part is in place in said through hole in a fastening device locking state, wherein the implant device is adjustable and connected to an implant device feed member, characterized in that the protruding part on the second fastening section is arranged with a through channel having an inlet and an outlet, said through channel being arranged to receive the implant device feed member, wherein the implant device feed member is arranged to be a locking member, locking the two fastening sections with the protruding part placed in the through hole and for being involved in the adjustment of the implant device by feeding at least one of a hydraulic or pneumatic fluid, electrical energy and an electrical signal to the implant device, wherein said inlet and outlet is accessible from the exterior of the fastening device in said fastening device locking state, wherein the first fastening section is detachably and securely locked to the second fastening section when, in said fastening device locking state, said implant device feed member is in place in the through channel and protrudes from both the inlet and the outlet of said through channel, wherein said fastening device is adapted to be reversible in two steps, involving to remove said implant device feed member from the through channel and thereafter detaching the first fastening section from the second fastening section.
2. The fastening device as claimed in claim 1 , wherein the first fastening section has a cylindrical, tubular or band shaped cross-section.
3. The fastening device as claimed in claim 2 , wherein the first fastening section has a tubular cross-section, and that the through hole is arranged at least through one wall of the tubular first fastening section.
4. The fastening device as claimed in claim 1 , wherein the second fastening section has a cylindrical, tubular or band shaped cross-section.
5. The fastening device as claimed in claim 1 , wherein the first and the second fastening sections are arranged on a same fastening unit.
6. The fastening device as claimed in claim 5 , wherein the fastening unit is attached to the implant device.
7. The fastening device as claimed in claim 5 , wherein the implant device feed member is attached to the fastening unit.
8. The fastening device as claimed in claim 1 , wherein the first and the second fastening sections are arranged on separate fastening units.
9. The fastening device as claimed in claim 8 , wherein at least one of the fastening units is attached to the implant device.
10. The fastening device as claimed in claim 8 , wherein the implant device feed member is attached to the fastening unit.
11. The fastening device as claimed in claim 1 , wherein the inlet and the outlet of the through channel arranged in the protruding part on the second fastening section are arranged on the same side of the first fastening section in the fastening device locking state.
12. The fastening device as claimed in claim 1 , wherein the inlet and the outlet of the through channel arranged in the protruding part on the second fastening section are arranged on different sides of the first fastening section in the fastening device locking state.
13. The fastening device as claimed in claim 12 , wherein the inlet and the outlet of the through channel arranged in the protruding part on the second fastening section are arranged on opposite sides of the first fastening section in the fastening device locking state.
14. The fastening device as claimed in claim 1 , wherein the outlet of the through channel arranged in the protruding part on the second fastening section is arranged to connect to an inlet of a through hole arranged in the second fastening section, wherein the inlet of the through channel arranged in the protruding part on the second fastening section and the outlet of the through hole in the second fastening section are arranged on different sides of the first fastening section in the fastening device locking state.
15. The fastening device as claimed in claim 1 , wherein the inlet and the outlet of the through channel arranged in the protruding part on the second fastening section are arranged adjacent the surface of the first fastening section in the fastening device locking state.
16. The fastening device as claimed in claim 1 , wherein the protruding part arranged on the second fastening section is arranged to protrude substantially axially from one end of the second fastening section.
17. The fastening device as claimed in claim 16 , wherein the inlet and the outlet of the through channel arranged in the protruding part on the second fastening section are arranged on different sides of the second fastening section.
18. The fastening device as claimed in claim 1 , wherein the protruding part arranged on the second fastening section is arranged to protrude substantially perpendicular to the longitudinal axis of the second fastening section, and from one end of the second fastening section.
19. The fastening device as claimed in claim 1 , wherein the protruding part arranged on the second fastening section is arranged to protrude substantially perpendicular to the longitudinal axis of the second fastening section.
20. The fastening device as claimed in claim 19 , wherein the protruding part arranged on the second fastening section is arranged adjacent to one end of the second fastening section.
