摘要：
An attachment surface for an implantable device has an irregular pattern (46,47,45,44,40) formed through a process including masking, chemical or electrochemical etching, blasting and debris removal steps. Surface material is removed from the implant surface without stress on the adjoining material and the process provides fully dimensional fillet radii at the base of the surface irregularities. This irregular surface is adapted to receive the ingrowth of bone material and to provide a strong anchor for that bone material which is resistant to cracking or breaking. The surface is prepared through an etching process which utilizes the random application of a maskant and subsequent etching in areas unprotected by the maskant. This chemical etching process is repeated a number of times as necessitated by the nature of the irregularities required in the surface. The blasting and debris removal steps produce microfeatures (150) on the surface that enhance the ingrowth of bone material.
摘要（中）：
用于可植入装置的附接表面具有通过包括掩模，化学或电化学蚀刻，喷砂和碎屑去除步骤的工艺形成的不规则图案（46,47,45,44,40）。 将表面材料从植入物表面上移除，而不会在相邻的材料上产生应力，并且该工艺在表面不规则的基部处提供完全尺寸的圆角半径。 该不规则表面适于接收骨材料的向内生长并且为该骨材提供一种坚固的锚固件，该锚固材料耐开裂或破裂。 通过蚀刻工艺制备表面，其利用掩蔽剂的随机施加和随后的蚀刻在不被掩蔽剂保护的区域中。 根据表面所需的不规则性的特性，重复该化学蚀刻工艺多次。 喷砂和碎屑去除步骤在表面上产生增强骨材料向内生长的微特征（150）。
