摘要： Disclosed is 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. According to the present invention, 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. According to the present invention, the seal is tightly attached to in vivo implant components, such that the wear debris cannot escape, and a friction force between the seal and the in vivo implant is smaller than a force for driving the components to generate relative motion, such that the relative motion between the components may not be blocked, thereby solving the problem of wear debris escaping.
