Introduction There are three levels of International Standard dealing with non-active surgical implants. These are as follo

29、ws, with level 1 being the highest: level 1: general requirements for non-active surgical implants and instrumentation used in association with implants; level 2: particular requirements for families of non-active surgical implants; level 3: specific requirements for types of non-active surgical imp

30、lant. This International Standard is a level 2 standard and contains requirements that apply to all non-active surgical implants in the family of joint replacement implants. The level 1 standard contains requirements that apply to all non-active surgical implants. It also indicates that there are ad

31、ditional requirements in the level 2 and level 3 standards. The level 1 standard has been published as ISO 14630. Level 3 standards apply to specific types of implants within a family, such as knee and hip joints. To address all requirements, it is recommended that a standard of the lowest available

32、 level be consulted first. 5 EN ISO 21534:2009 (E) DIN EN ISO 21534:2009-08 1 Scope This International Standard specifies particular requirements for total and partial joint replacement implants, artificial ligaments and bone cement, hereafter referred to as implants. For the purposes of this Intern

33、ational Standard, artificial ligaments and their associated fixing devices are included in the term “implant“. It specifies requirements for intended performance, design attributes, materials, design evaluation, manufacturing, sterilization, packaging and information to be supplied by the manufactur

34、er. Some tests required to demonstrate conformance to this International Standard are contained in or referenced in level 3 standards. 2 Normative references The following referenced documents are indispensable for the application of this document.

(Revision of ISO 14630:2005) 6 DIN EN ISO 21534:2009-08 EN ISO 21534:2009 (E) 3 Terms and definitions For the purposes of this document, the terms and definitions in ISO 14630 together with the following apply. 3.1 artificial ligament device, inc

40、luding its necessary fixing devices, intended to augment or replace the natural ligament 3.2 joint replacement implant implantable device, including ancillary implanted components and materials, intended to provide function similar to a natural joint and which is connected to the corresponding bones

41、 3.3 mean centre position within the spherical head for which the average of the distances to a set of points uniformly distributed over the surface of the sphere is minimum 3.4 radial separation value difference between the mean radius of the spherical surface and the radius to the point on the sph

42、erical surface furthest from the mean centre NOTE The units of the radial separation value are in micrometres. 4 Intended performance For the purpose of this International Standard, the intended performance of implants shall conform to Clause 4 of ISO 14630:, and the design input shall additionally

43、address the following matters: a) intended minimum and maximum relative angular movement between the skeletal parts to which the joint replacement implant is attached; b) expected maximum load actions (forces and moments) to be transmitted to the bony parts to which the joint replacement implant is

44、attached; c) dynamic response of the body to the shape/stiffness of the implants; d) expected wear of articulating surfaces; e) suitability of the dimensions and shape of the implant for the population for which it is intended; f) strength of the adhesion and durability of surface coatings or surfac

45、e treatments. NOTE 1 The clinical indications and contra-indications for the use of a particular implant are complex and should be reviewed by the surgeons when they are selecting implants to be used for particular patients, relying upon their own personal judgment and experience. NOTE 2 The lifetim

46、e of an implant depends on the interaction of various factors; some are the responsibility of the manufacturer, some, such as the implantation technique, are the responsibility of the surgeon in conducting the operation, and some relate to the patient, for example, the biological and physiological r

47、esponse to the implant, the medical condition of the patient, the conduct of the patient in respect of increasing body weight, carriage of heavy loads and adopting a high level of physical activity. 7 EN ISO 21534:2009 (E) DIN EN ISO 21534:2009-08 5 Design attributes 5.1 General The development of t

48、he design attributes to meet the performance intended by the manufacturer shall conform to the requirements of Clause 5 of ISO 14630:, and in addition, account shall be taken of the following points: a) the strength of adhesion and durability of surface coatings and surface treatments; b) the wear o

49、f the articulating and other surfaces; c) stability of the implant while allowing prescribed minimum and maximum relative movements between the skeletal parts; d) avoidance of cutting or abrading tissue during function other than insertion or removal; e) the creep resistance and rupture characteristics, particularly as they relate to ligaments. NOTE 1 Methods of assessment of the wear of articulating and other surfaces are prescribed in, e.g. ISO 14242-2 and ISO 14243-1, -2 and -3. NOTE 2 More specific requirements, such as th
