BONE PLATE FASTENING SYSTEM

A screw guide includes a first end, a second end spaced from the first end, a guide body that extends from the first end to the second end, and a guide hole that extends through the guide body. The guide body includes a first guide surface and a second guide surface, the first guide surface defines a first opening of the guide hole, and the second guide surface is spaced from the first guide surface in a first guide direction. The second guide surface defines a second opening of the guide hole, the guide body includes a leg portion that extends from the second guide surface in the first guidedirection such that the leg portion is spaced from the second opening in a second guide direction that is perpendicular to the first guide direction. 本发明公开了一种螺钉引导件，其包括：第一端部、与该第一端部间隔开的第二端部、从该第一端部延伸到该第二端部的引导件主体，和延伸穿过该引导件主体的引导件孔。该引导件主体包括第一引导件表面和第二引导件表面，该第一引导件表面限定该引导件孔的第一开口，并且该第二引导件表面沿第一引导件方向与该第一引导件表面间隔开。该第二引导件表面限定该引导件孔的第二开口，该引导件主体包括支腿部分，该支腿部分沿该第一引导件方向从该第二引导件表面延伸，使得该支腿部分沿垂直于该第一引导件方向的第二引导件方向与该第二开口间隔开。
