摘要： The present disclosure relates generally to a retractor device for allowing visible access to the surgical site. According to particular embodiments, the present retractor may include two portions: an integral arm portion at one end and a textured surface potion at the opposite end. In some embodiments, the integral arm portion may be positioned inside the body cavity of the patient to restrain and/or occlude targeted organs during surgery to allow for increased visibility of other organs and/or portions of a patient during surgical procedures.

摘要： Devices and methods for temporarily retaining spinal rootlets within a dural sac are provided. In this regard, a representative device includes: a handle operative to be grasped by a user; an arm extending outwardly from the handle; and moveable fins supported at a distal end of the arm, the fins being moveable between an unbiased position and a biased position; in the biased position, free ends of the fins having been moved toward each other such that an extent of the fins along a major axis is decreased relative to an extent of the fins along the major axis in the unbiased position.

摘要： A pedicle insulator implant is designed to protect the nerves and surrounding tissue from injury by pedicle screws or other surgical devices and instruments. In its basic structure, the implant has a thicker section and a thinner section, the thicker section providing protection for nerves and other sensitive tissues while the thinner section can be deformable and provides grip. In one variation of the basic structure, the thinner section possess a rough surface when it is desirable in situations to provide further grip of the assembly and prevent rotation during the insertion of, for example, a pedicle screw.

摘要： A surgical instrument and method for forming a passage in bone having an enlarged cross-sectional portion is provided. The instrument includes an elongate member and a cutting element engaged thereto and transitionable between a retracted configuration for extending through a first portion of the passage and an expanded configuration for forming a second portion of the passage having an enlarged cross-section. In one embodiment, the cutting element is transitioned between the retracted and expanded configurations by axially displacing the cutting element relative to the elongate member. In another embodiment, the elongate member includes a tapping thread configured to cut threads along the first portion of the passage, and the cutting element is a blade configured to form the enlarged cross-section when transitioned to the expanded configuration. In another embodiment, the cutting element is arranged in an axial orientation when in the retracted configuration and an angular orientation when in the expanded configuration.
