摘要： A surgical scalpel includes an elongate handle that has a proximal end, a open distal end and sidewalls that define an upwardly open cavity with a bottom with an open void therein. The sidewalls each have an elongate channel therein. The scalpel of the invention includes a cartridge that is removably retained within the cavity. The cartridge includes a shield. The cartridge has a blade holder with a proximal end and a distal end mounted within the shield for slidable movement between a proximal and a distal position. There is a latch on the blade holder for engaging the handle and the shield to retain releasably the blade holder in the distal position and the proximal position. The scalpel has a blade fixedly attached to the blade holder so that when the blade holder is in the distal position, the blade projects distally from the handle. When the blade holder is in the proximal position, the blade is within the shield and the handle and thus substantially protected from inadvertent exposure.
摘要翻译：外科手术刀包括细长手柄，其具有近端，敞开的远端和限定向上敞开的空腔的侧壁，其中底部具有开放的空隙。侧壁各自在其中具有细长的通道。本发明的手术刀包括可拆卸地保持在腔内的药筒。盒包括屏蔽。药筒具有刀片保持器，其具有近端并且远端安装在护罩内，用于在近端位置和远端位置之间滑动。在刀片保持器上有一个闩锁，用于接合手柄和屏蔽件，以将刀片保持器可释放地保持在远侧位置和近端位置。手术刀具有固定地附接到刀片保持器的刀片，使得当刀片保持器处于远侧位置时，刀片从手柄向远侧突出。当刀片保持器处于近侧位置时，刀片在护罩和手柄内，因此基本上防止了意外的暴露。
