摘要： The invention relates to an artificial chamber that can support and pressurize a donor cornea to extract a corneal graft. The artificial chamber has a stationary stem that is adapted to support a cornea. The stem has an inner channel that allows air to pressurize the cornea. The artificial chamber has an outer cap that can be moved in a downward direction to secure the cornea. The cap has an opening that exposes a portion of the cornea to allow for the extraction of a corneal graft. The outer cap is attached to an outer sleeve that is moved by rotation of a cam. The chamber includes a spring that exerts a clamping force onto the cornea. The clamping force can be adjusted by rotating an adjustment wheel. The adjustable spring force allows an operator to set a desired clamping force that is then repeated for each grafting procedure.

摘要： A system that can be used to perform an ophthalmic procedure. The system may include a patient support that supports a patient and a light source which can direct a beam of light onto the patient's cornea. The system may also include an airflow module that directs a flow of air above the cornea. The flow of air reduces the amount of contaminants that may become attached to the cornea during the procedure.

摘要： A blade assembly that can be assembled into a microkeratome which is used to cut a cornea. The blade assembly is constructed in a manner that minimizes the tolerance of the cutting depth into the cornea. The blade assembly includes a blade holder that can be pressed onto a blade. The relative position of the blade holder can be calibrated to control the distance between a reference surface of the blade holder and the cutting edge of the blade. This distance defines the cutting depth of the blade. The blade holder is coupled to the blade with an interference fit that both secures the holder while providing for calibration of the assembly.

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 surgical cutting system. The cutting system includes a cutter which has an inner sleeve that moves adjacent to an aspiration port of an outer sleeve. The inner sleeve is coupled to a source of vacuum that pulls tissue into the outer port when the inner sleeve is moved away from the port. The inner sleeve then moves across the outer port and severs the tissue in a guillotine fashion. The tip of the inner sleeve may exert a spring force that assist in the cutting action of the cutter. The cutter includes a motor which creates an oscillating translational movement of the sleeve. The motor can be controlled by a controller that is coupled a foot pedal. The foot pedal and controller can be configured so that the motor decreases speed as the pedal is depressed by the operator. The inner sleeve is coupled to an aspiration line that pulls the severed tissue out of the cutter. The level of the aspiration vacuum pressure can be controlled by a variable regulator valve. The regulator valve is coupled to the controller and the foot pedal. The foot pedal may have a switch that allows the system to operate in either a variable speed mode or a variable pressure mode. In the variable speed mode the actuation of the foot pedal changes the speed of the motor in the variable pressure mode the actuation of the foot pedal changes the vacuum level within the aspiration line.

摘要： A medical device that can be used to cut a cornea. The device includes a blade that is located within an opening of a ring. The ring can be placed onto a cornea. The device may further have a first drive mechanism that moves the blade in a first direction and a separate second drive mechanism that moves the blade in a second direction. The first drive mechanism may be controlled by a first input device. The second drive mechanism may be controlled by a second input device. The separate input devices and drive mechanisms may allow a surgeon to vary the shape and size of the corneal cut.

摘要： A medical device that can be used to cut a cornea. The device may include a blade that is coupled to a head by a blade holder. The device may also have a retention spring that exerts a force on the blade and blade holder. The head and blade can be moved across a ring by a drive assembly that contains a lead screw. The ring may contain one or more openings which have a length that is greater than a width. The openings may be coupled to a vacuum source by a tube. The vacuum pressure of the tube can be displayed by a console. The console may also have switches that allow different operating parameters to be entered through a single knob.
