摘要： A microkeratome that includes a latch assembly that couples a head to a hand piece. The latch assembly allows the head to be readily detached from the hand piece and sterilized. There is no need to also sterilize the hand piece. The microkeratome also has a ring assembly that is coupled to the head and the hand piece. The ring assembly may include a fastener that can be unfastened to allow the hand piece and head to be detached from the ring, even while the ring assembly is fixed to a cornea. The hand piece includes a motor that moves the blade across the ring. The microkeratome may have an aspiration connector with a collar that limits the travel of the blade the and thickness of a resulting lamella flap. The aspiration connector can be replaced with a collar of a different diameter to produce a flap with a different thickness.
摘要翻译：一种微型角膜刀，其包括将头部连接到手持件的闩锁组件。闩锁组件允许头部容易地从手持件上分离并消毒。没有必要也对手部进行消毒。微型角膜刀还具有耦合到头部和手部件的环组件。环组件可以包括紧固件，即使在环组件被固定到角膜的时候，该紧固件可以被松开以允许手部件和头部与环分离。手持件包括使刀片穿过环的电机。微型角膜刀可以具有带有凸缘的抽吸连接器，其限制了刀片的移动和所得薄片瓣的厚度。抽吸连接器可以用不同直径的套环来代替，以产生具有不同厚度的翼片。

摘要： A microkeratome cutting head includes a head structure, an applanation plate, and a stromal plate. The head structure may include a blade cavity for receiving a blade and a blade opening through which the blade extends. The blade is configured for creating a corneal flap at a corneal flap thickness. The applanation plate is disposed at an elevation above the stromal plate plane. The elevation difference is approximately equal to the corneal flap thickness.
摘要翻译：微型角膜刀切割头包括头部结构，扁平板和基质板。头部结构可以包括用于接收刀片的刀片腔和刀片延伸穿过的刀片开口。刀片被配置为在角膜瓣厚度处产生角膜瓣。扁平板布置在基质板平面上方的高度处。高程差近似等于角膜厚度。

摘要： A microkeratome cutting head includes a head structure, an applanation plate, and a stromal plate. The head structure may include a blade cavity for receiving a blade and a blade opening through which the blade extends. The blade is configured for creating a corneal flap at a corneal flap thickness. The applanation plate is disposed at an elevation above the stromal plate plane. The elevation difference is approximately equal to the corneal flap thickness. An artificial anterior chamber (AAC) system is used to hold the donor eye for interfacing with the microkeratome. The AAC system includes an optional pressure valve and pressure gauge in a closed loop system for the user or surgeon to control line pressure applied to the donor eye during the procedure.
