    • The stop element is set forth for solving a problem of the clinician only being able to visualize a depth marking on a drill bit or a similar tool. The detachable stop element limits the penetration of the drill bit beyond a predetermined axial distance on the drill bit. The stop element consists of a connecting portion and an extending portion, both having an inner wall defining a bore extending entirely through the connecting portion and extending portions. The connecting portion has a surface that contacts the drill bit for restricting the axial movement of the stop element relative to the drill bit. The extending portion terminates in a lower end for engaging the bone surrounding the bore to limit the penetration of the drill bit. The stop element may include a plurality of grooves for altering its length so that the penetration depth of the drill bit can be altered.
    • 为了解决临床医生仅能够可视化钻头或类似工具上的深度标记的问题,提出了止动元件。 可拆卸的止动元件将钻头的穿透力限制在钻头上的预定轴向距离之外。 止挡元件由连接部分和延伸部分组成,两者都具有限定穿过连接部分延伸的延伸部分的内壁的内壁。 连接部分具有接触钻头的表面,用于限制止动元件相对于钻头的轴向运动。 延伸部分终止于下端,用于接合围绕孔的骨骼以限制钻头的穿透。 止动元件可以包括用于改变其长度的多个槽,使得钻头的穿透深度可以改变。
