    摘要: A device, system and method for orthopedic spine surgery using a novel screw-based retractor, disclosed herein, that allows for access to the spine through a minimally or less invasive approach. The retractor device is designed as a co-molded part of the tulip of a pedicle screw assembly with opposed arms of the retractor spread apart to open the wound proximally. The arms are removed by separating the arms from the tulip and removing them from the incision. The retractor device is intended to be made of a relatively stiff material, sterile packaged and disposable after one use. A system and method for using the retractor and performing a minimally invasive spine surgical procedure are also disclosed.

    摘要: A retractor having a pair of blades is disclosed. A ring having an opening is attached to one end of the blades. The blades define a channel therebetween. The blades may be pivotally coupled to the ring. The retractor may have at least two conditions. In a first condition, the retractor is insertable through an incision in a patient's skin to an operative site. In a second condition, the retractor may be manipulated for retracting tissue surrounding the operative site. Instruments, prostheses, or tissue may be inserted or removed through the channel of the retractor.

    摘要: A spinal fixation device includes a proximal surface having a first portion defining a first plane and a second portion defining a second plane. The first and second planes define a first angle in relation to each other. The first and second planes define first through holes and a second through hole, respectively. The first through holes each define a first longitudinal axis, and the second through hole defines a second longitudinal axis. In particular, the first and second longitudinal axes define a second angle in relation to each other. The first through holes define a first center line on the first plane, and the second through hole defines a second center line on the second plane. The first and second center lines are disposed on opposite sides of a center line defined by the proximal surface.
