摘要： A scalpel of the present invention includes an elongate handle defining a longitudinal axis and having a proximal end and a distal end. The scalpel of the invention further includes a cartridge that is removably mounted to the handle. The cartridge has blade holder with a proximal end and a distal end with a blade fixedly attached that is disposed so that the blade projects distally outwardly when the cartridge is mounted to the handle. The cartridge also includes a shield that is slidably mounted onto the blade holder for movement between a distal position where the shield substantially prevents inadvertent access to the blade and a proximal position where the shield substantially surrounds a portion of the handle and the blade is exposed for use. The cartridge is releasably mountable on the handle. The shield is substantially prevented from movement to the proximal position unless the cartridge is mounted on the handle and not dismountable from the handle unless the shield is in the distal position.
摘要翻译：本发明的解剖刀包括限定纵向轴线并具有近端和远端的细长手柄。本发明的手术刀还包括可移除地安装到手柄的盒。盒具有具有近端的刀片保持器和具有固定地附接的刀片的远端，刀片被设置成使得当药筒安装到手柄时刀片向远侧突出。该暗盒还包括一个可滑动地安装在刀架上的护罩，用于在护罩基本上防止无意中进入刀片的远端位置和护罩基本上围绕手柄的一部分而暴露的近端位置之间移动使用。盒可释放地安装在手柄上。基本上防止了屏蔽件移动到近侧位置，除非该盒被安装在把手上，而不能从手柄拆卸，除非屏蔽件处于远端位置。

摘要： A surgical scalpel includes an elongate handle defining a longitudinal axis and having a proximal end and a distal end. The scalpel has a cartridge removably mounted to the handle that has a blade holder with a proximal end and a distal end. There is a blade fixedly attached to blade holder disposed so that the blade projects distally outwardly when the cartridge is mounted on the handle. The cartridge also has a shield with a proximal end, a distal end and a bottom mounted onto the blade holder. The shield is slidably movable between a distal position where the shield substantially prevents inadvertent access to the blade and a proximal position where the shield substantially surrounds a portion of the handle and the blade is exposed for use. The cartridge is releasably mountable to the handle and has elements for substantially preventing movement of the shield with respect to the blade holder unless the cartridge is mounted on the handle. The cartridge further including elements for substantially preventing an inadvertent movement of the shield to the proximal position thereby to expose the blade as the cartridge is being mounted to the handle.
摘要翻译：外科手术刀包括限定纵向轴线并具有近端和远端的细长手柄。手术刀具有可移除地安装到手柄的盒，其具有具有近端和远端的刀片保持器。存在固定地连接到刀片保持器上的刀片，其被布置成使得当药筒安装在手柄上时刀片向远侧突出。药筒还具有护罩，其具有近端，远端和安装在刀架上的底部。所述护罩可在远端位置和所述护罩基本上围绕所述手柄的一部分并且所述刀片暴露于使用的远侧位置之间可滑动地移动，所述远端位置处所述护罩基本上防止无意中进入所述刀片。盒可释放地安装到手柄上并且具有用于基本上防止屏蔽件相对于刀片保持器移动的元件，除非该盒被安装在手柄上。该盒还包括用于基本上防止屏蔽件向近侧位置的无意移动的元件，从而当盒被安装到把手时露出刀片。
