Disclosed are a method for limiting diffusion of wear debris of an in vivo implant and an in vivo implant apparatus with a function of limiting wear debris. An elastomer seal is arranged at a wearing part between implant components that can move relatively and generate wear, such that an outlet for wear debris of the implant is always sealed within a sealing area formed by the seal and the implant components, thereby preventing the wear debris from diffusing outwards. The elastomer seal includes at least one flexible buffer part for reducing or completely offsetting relative motion between the implant components, thereby further reducing wear of a sealing part of the elastomer seal due to the relative motion between the parts. The seal is tightly attached to in vivo implant components, and the in vivo implant is smaller than a force for driving the components to generate relative motion.
A method for limiting diffusion of wear debris of an in vivo implant, wherein an elastomer seal is arranged at a wearing part between implant components that can move relatively and generate wear, such that an outlet for wear debris of the implant is always sealed within a sealing area formed by the seal and the implant components, thereby preventing the wear debris from diffusing outwards;
An in vivo implant apparatus with a function of limiting wear debris, wherein the in vivo implant apparatus comprises an implant formed by inserting and fitting an inner component and an outer component, the inner component and the outer component can relatively move to generate wear debris, an outlet for the wear debris of the implant is located at a port of the outer component that is cooperatively connected to the inner component, an elastomer seal is disposed on an insert fitting segment of the inner component and the outer component, wherein one part of the elastomer seal is tightly attached to a sleeve and is disposed on the inner component, and the other part of the elastomer seal is tightly attached to and connected with the outer component, the elastomer seal, the inner component and the outer component to form a sealing area wrapping the outlet for the wear debris, and a flexible buffer part is disposed between a sealing location on the inner component and a sealing location on the outer component.
