A method for hip distraction includes positioning a patient on a slide-resisting pad placed on a surgical table; tilting the surgical table so that the patient is in a first degree of inclination; applying a distraction force to a leg of the patient while the patient is in the first degree of inclination so that a hip joint of the patient is distracted, wherein the distraction force is opposed by a combination of a slide-resisting friction force provided by the slide-resisting pad and a gravitational force attributable to the first degree of inclination; reducing the tilt of the surgical table in accordance with a reduction of the distraction force over time so that the patient is in a second degree of inclination; and performing at least a portion of a surgical procedure on the distracted hip joint while the patient is in the second degree of inclination.

A patient interface device for an ophthalmic surgical laser system includes a lens cone component for coupling to the laser system and a suction ring component for coupling to the patient's eye. The suction ring includes a gripper with an opening for receiving and retaining the lens cone, and a flexible skirt joined to the gripper for coupling to the eye with a vacuum force. The flexible skirt includes a circular inner edge and a circular outer edge for contacting the eye surface, and a plurality of circumferentially distributed scleral support protrusions protruding from a circumferential side wall. The end surface of the scleral support protrusions are sloped in a side cross-sectional view. The scleral support protrusions have a length to width ratio from 1.1 to 2.1, and an arc-angle ratio of the scleral support protrusions to the gaps between them is from 2.2 to 3.0. The scleral support protrusions contact the surface of the eye when the skirt is docked to the eye, which minimize intraocular pressure increase due to docking and applanation while still achieving a good vacuum seal between the suction ring and the eye. The scleral support protrusions function to prevent major deformation of the sclera when the cornea is applanated.

In an ophthalmic surgical laser system, a patient interface device for coupling a patient's eye to the laser system includes a lens cone with a frustoconical shaped shell for coupling to the laser system and a suction ring for coupling to the patient's eye, the lens cone and the suction ring being joined together by clamping. A cap is provided for use with the lens cone as an installation aid. In the configuration supplied to the user, the lens cone is partially embedded in and snapped to the cap. The cap has a portion with a relatively large diameter and multiple ribs for easy handling. The user holds the cap to install the lens cone on the laser system, and pulls the cap to unsnap it from the lens cone. The lens cone is attached to the laser system with a bayonet mount that provides tactile feedback to the user.

Improved corneal lenticule extraction tools which integrate defined angles, tip features, and the use of vacuum into the tool to aid in the removal of the lenticule. The tool has a body and a tip each with an internal air channel. The tip has a straight portion and a curved portion at a distal end, with one or more orifices disposed on the curved portion. The body either has a mechanism for generating a vacuum in the internal air channel, such as a resilient diaphragm, or is connected to an external vacuum source. Use of tip features and angles helps the surgeon find tissue edges during tissue removal. The use of vacuum aids to draw the tissue to the tool and to hold the tissue by the tool. The improved tools improve speed of extraction as well as completeness of extraction so that no tissue is left behind.
