Embodiment Construction

[0044] The present disclosure relates to devices, systems and methods for coupling a plunger tip to a plunger of an intraocular lens (IOL) injection device. figure 1 An exemplary handheld IOL injection device 10 for implanting an IOL into the anterior capsule of the eye is shown. As shown, the IOL injection device 10 includes a cable assembly 12 that carries control signals and / or power from a separate user console (not shown), although some embodiments may include one or Batteries to power the device, and / or one or more switches or other user input devices to control the operation of the device. The IOL injection device 10 shown in the figures may also include a cartridge mount 18 that holds a removably mounted insertion cartridge 20 . As will be explained in further detail below, the insertion barrel 20 in some embodiments is adapted to accommodate a deployed IOL lens and to fold and move the plunger tip 25 as it translates forward from the body of the housing 15 and throug...

Abstract

The present disclosure is directed to devices, systems, and methods directed to mounting a plunger tip to a plunger of an IOL injection device. A plunger tip wrench that is operable to releasably retain a plunger tip may be coupled to a holder extending from an end of the IOL injection device to align the plunger tip with the plunger of the IOL injection device. In some instances, the IOL injection device may include a motor and use a back electromotive force (EMF) of the motor to detect a position of the plunger as it is extended to engage the plunger tip. The plunger tip may be positioned relative to the plunger such that the plunger will engage the plunger tip within the entire range of a negative error position and a positive error position.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation-in-part of prior application 12 / 249,996, filed October 13, 2008, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates generally to devices for delivering an intraocular lens into an eye, and more particularly to fault detection in such devices. Background technique [0004] The human eye functions to provide vision by transmitting light through a clear exterior called the cornea and focusing the image on the retina through the lens. The quality of the focused image depends on many factors, including the size and shape of the eye and the transparency of the cornea and lens. When age and disease cause the lens to become less transparent, vision deteriorates due to a reduction in the light that can be transmitted to the retina. This defect in the lens of the eye is medically known as a cataract. An acceptable treatment for t...
