Abstract: Systems, devices, and methods suitable for use with procedures performed at least partially percutaneously are provided. In some procedures, two or more access devices for providing access to adjacent surgical locations within a patient are used. Certain embodiments of the access device comprise an elongate body having a distal end with one or more cutouts. The cutouts on adjacent access devices are generally aligned with each other to permit passage of a portion of a fixation element from one access device to the other access device. A fastener with an elongated removable head may be delivered to the surgical site through the access device. After a distal end of the fastener is secured to the surgical site, a portion of the elongated housing is detached from the remainder of the fastener and removed from the patient.

Abstract: This disclosure provides an efficient, hands-free system and method for capturing and recording patient data in critical care environments. The systems and methods described herein enables clinicians to record and transcribe patient information onto a disposable medical record tag (akin to a military ID tags), which accompanies the patient throughout initial stabilization and presentation to a treatment center. A Pre-Hospital Treatment & Triage (PHT) guidance system, visible in the HMD, can guide caregivers and/or first responders through treating the patient and documenting a patient's medical condition and treatment status, and triaging patients to the appropriate level of care. The head-mounted display can wirelessly transfer the patient's treatment data to a lightweight disposable data tag, referred to as an electronic TCCC (E-TC3) that is affixed to the patient. The data tag digitally stores a patient's health status, and displays a specific color based on a patient's degree of injury.
