Certain aspects of the present disclosure provide to angle adjustment systems using one or more spring arrangements. In certain aspects, an angle adjustment system comprises a component and a first spring arrangement coupled to the component, wherein the first spring arrangement comprises at least three spring elements. Further, the first spring arrangement is configured to allow the component to rotate around a first axis of rotation and prevent a first translational movement of the component with respect to the first axis of rotation.

Angle adjustment system

An ultrasonic cutting tip has a hollow shaft with a proximal and distal end. The proximal end is configured to be attached to an ultrasonic hand piece, and the distal end has a smooth continuous surface. An opening is located near the distal end of the hollow shaft. The opening is configured to cut vitreous when the cutting tip is vibrated ultrasonically in a torsional manner.

Ultrasonic vitreous cutting tip

Various optical fiber cables and systems and methods associated therewith are disclosed herein. An optical fiber cable may include a jacket, an optical fiber and a metal wire disposed within a passage defined by the jacket. The metal wire may be coupled to the optical fiber.

Metal wire for optical fiber cable and strain relief

Both visible and IR cameras are integrated without an increase in an optical stack height of a surgical microscope used for ophthalmic surgery. The IR camera may be used to directly and intraoperatively capture a scanning OCT measurement beam, which uses NIR light that is invisible to the human eye. An IR image from the IR camera taken from the same surgical field as displayed intraoperatively to a user of the surgical microscope may be displayed in an ocular to the user, enabling visualization of a location of an OCT scan along with actual visible images of the surgical field.

A foot-operated controller includes a base configured to rest on a floor surface, and a movable contact surface coupled to the base. The contact surface includes an anterior region to support a toe region and a posterior region to support a heel region, and is configured to roll about a roll axis in response to inversion or eversion of a foot engaged with the contact surface, pitch about a pitch axis in response to plantar flexion or dorsiflexion of the foot, and yaw about a yaw axis in response to abduction or adduction of the foot. The roll, pitch, and yaw axes intersect at a point superior to the contact surface, and may align with the operator's ankle.

An optical coherence tomography (OCT) system and method for cross view imaging using at least two B-scan images transformed and coupled to each other at an angle to generate a cross view image.

Methods and systems for anti-parallax correction of stereoscopic surgical images may employ a stereoscopic surgical microscope to generate overlay content as left and right digital images that are overlaid on respective left and right analog images from an objective field of view of the surgical microscope. The user may select a location-dependent feature in the overlay content and may select left or right for the anti-parallax correction.

Anti-parallax correction of stereoscopic surgical images

An optical light scanning probe is presented, the probe comprising a handle, shaped for grasping by a user; a cannula, protruding from a distal portion of the handle with an outer diameter smaller than 20 gauge; an optical fiber with a distal fiber-portion off a probe-axis, configured to receive a light from a light-source at a proximal fiber-portion, and to emit the received light at the distal fiber-portion; a fixed beam forming unit, disposed at a distal portion of the cannula, configured to receive the light from the distal fiber-portion, and to deflect the received light toward a target region; and a fiber actuator, housed at least partially in the handle, configured to move the distal fiber-portion to scan the deflected light along a scanning curve in the target region.

Forward scanning-optical probes, circular scan patterns, offset fibers

In certain embodiments, a scanning system comprises optical elements and a movement system. The optical elements comprise an optical fiber and a focusing element. The optical fiber transmits a light ray and has a fiber axis that extends to an imaginary fiber axis. The focusing element refracts the light ray and has a focusing element optical axis that is substantially aligned with the imaginary fiber axis. The movement system rotates the focusing element about the focusing element optical axis to scan the light ray. In other embodiments, a scanning system comprises optical elements and a movement system. The optical elements comprise an optical fiber, a focusing element, and a prism. The prism has a prism optical axis and receives the light ray from the focusing element. The movement system rotates the prism about the prism optical axis to scan the light ray.
