    • A surgical knife safety device (10 or 100) having a handle (20 or 120), a blade (40 or 140) connected to the handle, and a guard (30 or 130) carried by the handle for sliding movement between a retracted position in which the blade is exposed for use, and an extended position for covering the sharp cutting edge of the blade. In the retracted position, an enlarged guard (30 or 130) radius is provided at the distal end of the handle (20 or 120) to allow improved handle control and blade orientation. The enlarged guard radius is positioned to allow the user to firmly grip a large distal handle portion which is preferably molded as a single piece with the blade holder (26 or 126), preventing unwanted blade or handle movement due to guard mechanism tolerances. A spring, such as leaf spring (52 or 152), and a pair of detents (54, 56) or slots (154,156) are provided to fix the guard (30 or 130) in the extended or retracted position, and provide resistance during movement between the two positions. Additionally, an antitravel mechanism is incorporated in the guard to prevent accidental retraction from the fully extended position.
    • 具有手柄(20或120)的外科手术刀安全装置(10或100),连接到手柄的刀片(40或140)以及由把手承载的防护件(30或130),用于在缩回位置 其中刀片被暴露以使用,以及用于覆盖刀片的尖锐切削刃的延伸位置。 在缩回位置,在手柄(20或120)的远端处设置有放大的护罩(30或130)半径,以允许改进的手柄控制和刀片取向。 放大的防护半径被定位成允许使用者牢固地握住优选地用刀片保持器(26或126)模制成单件的大型远端把手部分,防止由于保护机构公差而引起的不期望的刀片或手柄的移动。 提供诸如片簧(52或152)和一对棘爪(54,56)或狭槽(154,156)的弹簧以将防护件(30或130)固定在延伸或缩回位置,并且在 两个位置之间的移动。 此外,防护装置结合在防护装置中以防止从完全伸出位置的意外收回。
