摘要： A surgical hand piece is described that maintains a vacuum pressure within the hand piece at a selected level. A check valve is provided substantially near an inlet of an integrated aspirating pump. The check valve opens to introduce fluid into the hand piece to maintain the vacuum pressure within the hand piece at or above the selected level so as to prevent or substantially reduce post-occlusion flow.

摘要： A system for implanting an intraocular lens in the lens capsule of an eye to treat an ocular condition includes a housing, a plunger, and an electric motor configured to cause longitudinal translation of the plunger. A cartridge mount may accommodate a removable insertion cartridge so that an intraocular lens disposed in the insertion cartridge is displaced from the insertion cartridge as the plunger is translated. A controller electrically communicates with the electric motor and powers the electric motor to translate the plunger and displace the intraocular lens. The controller may be configured to detect motor current feedback in the control circuit and may be configured to compare the detected motor current feedback to a stored current profile and to stop translation of the plunger when the current level deviates from the stored current profile by a pre-stored amount.

摘要： A surgical system comprises a pressurized irrigation fluid source; an irrigation line fluidly coupled to the pressurized irrigation fluid source; a hand piece fluidly coupled to the irrigation line; an irrigation pressure sensor located at or along the pressurized irrigation fluid source or irrigation line; and a controller for controlling the pressurized irrigation fluid source. The controller controls the pressurized irrigation fluid source based on a reading from the irrigation pressure sensor and an estimated flow value modified by a compensation factor.

摘要： In various embodiments, a phacoemulsification cutting tip with a straight shaft and an angled portion off of the straight shaft may include a hook on the angled portion to move an axis of rotation of the cutting tip closer to alignment with an extended centerline of the shaft. The cutting tip may be configured to torsionally rotate back and forth on an axis perpendicular to a centerline of the shaft (e.g., rotation around a y-axis). In some embodiments, lateral vibrations (e.g., side to side along an x-axis or z-axis perpendicular to the y-axis) that result from torsional rotation around the y-axis in a cutting tip without the hook may be reduced through use of the hook to balance the otherwise eccentrically weighted hook.
摘要翻译： 在各种实施例中，具有直轴和离开直轴的成角度部分的超声乳化切割尖端可以包括在成角度部分上的钩，以使切割尖端的旋转轴线更靠近与轴的延伸中心线对准。 切割尖端可以构造成在垂直于轴的中心线的轴线（例如，围绕y轴的旋转）上来回扭转。 在一些实施例中，可以通过使用减少在没有钩的切割尖端中围绕y轴的扭转旋转引起的横向振动（例如，沿着垂直于y轴的x轴或z轴的一侧到另一侧） 的钩子来平衡否则偏心加权的钩子。
