This disclosure includes an expansion driver for adjusting expandable implants, the expansion driver including an input shaft operably connected to at least one bevel gear, the at least one bevel gear configured to engage each of a first gear and a second gear; the first gear connected to a first output shaft, the first output shaft terminating in a first driver configured to communicate with a first actuator of an expandable implant; the second gear connected to a second output shaft, the second output shaft annularly disposed around at least a portion of the first output shaft; and at least one pinion configured to transfer a torque from the second output shaft to a second driver extending parallel to the first driver and configured to communicate with a second actuator of the expandable implant. Upon a rotation of the input shaft, a torque is applied to at least one of the first driver and the second driver.
A method for performing a surgical procedure includes: positioning a patient in a surgical patient interface device that includes: a base, a platform coupled to the base, and a first abutment and a second abutment each coupled to the platform; rotating the platform between a first position and a second position, where, in the first position, the platform extends in a substantially horizontal direction relative to the base, and the first and second abutments are separated by a first distance, and in the second position, the platform extends in a substantially vertical direction relative to the base; adjusting one or both of the first and second abutments relative to the platform such that, in the second position, the first and second abutments are separated by a second distance different from the first distance; and accessing a target portion of skin of the patient for the surgical procedure.
An interbody implant to be introduced into a variety of target sites for accelerating bone ossification, for example into a space between two adjacent vertebrae. The interbody implant includes a first bone contacting surface, a second bone contacting surface, a body defined between the first and second bone contacting surfaces, and a plurality of resonators. Mechanical waves, e.g., low intensity pulsed ultrasound waves, may be transmitted to the location of the implant, causing the resonators to resonate and accelerate bone ossification.
A bone hook apparatus is provided that includes a base, a rod receptacle disposed on a proximal side of the base, a first hook distally extending from the base and oriented in a first direction, and a second hook distally extending from the base and oriented in a second direction opposing the first direction, the first hook and second hook together configured to receive the bone. Kits and spinal constructs employing the bone hook apparatus are also described.

Disclosed examples include those directed to detecting and remediating detachment of electrodes from a patient. In an example, a system calculates a Pearson correlation coefficient between: (1) power spectral density of the noise and (2) power spectral density of a recorded signal (e.g., from an electrode being operated in free-run EMG mode). If the recorded signal correlates with the noise, then the system notifies the user of presence of noise (e.g., the fallen electrode). Otherwise, the recorded signal is considered as the signal of interest (e.g., a valid EMG signal).

A61B 5/296 - Électrodes bioélectriques à cet effet spécialement adaptées à des utilisations particulières pour l’électromyographie [EMG]
A surgical access system including a tissue distraction assembly 40 and a tissue retraction assembly 10, both of which may be equipped with one or more electrodes 23 for use in detecting the existence of (and optionally the distance and/or direction to) neural structures before, during, and after the establishment of an operative corridor 15 to a surgical target site. The tissue retraction assembly 10 has a plurality of blades 12, 16, 18 which may be introduced while in a closed configuration, after which point they may be opened to create an operation corridor 15 to the surgical target site, including pivoting at least one blade 12, 16, 18 to expand the operative corridor 15 adjacent to the operative site.
