A lug not engaging tool in the form of a rod includes a first end for receiving a standard socket, and a second end for engaging a socket wrench or impact wrench. An intermediate portion has a hexagonal section for engaging an open end wrench or a closed end box wrench. The rod includes sections having differing diameters. In use, a jack or jack stand may be placed under a section having an appropriate diameter to ensure that the jack or jack stand supports the lug nut engaging tool in a position that is substantially perpendicular to the wheel as the tool is used to loosen or tighten a lug nut.

The present disclosure provides for spinal implants deployable between a contracted position and an expanded position. The spinal implant may include a first endplate and a second endplate, each having a plurality of guide walls and inclined ramps. The spinal implant may further include a moving mechanism having first and second trolleys configured to act against the first and second plurality of ramps. The expansion mechanism may further include a first set screw and a second set screw opposite the first set screw. The moving mechanism may be configured to operably adjust a spacing between the first and second endplates upon simultaneous rotation of the first and second set screws along a rotation axis, and may also operably adjust an angle of inclination between the first and second endplates upon rotating the first set screw or second set screw along the rotation axis.

Disclosed screwdrivers may include a rotatable drive shaft having a drive portion disposed at a distal end thereof, and a drive end disposed at a proximal end thereof. Disclosed screwdrivers may include an angled tip portion that is angled with respect to the longitudinal direction, and a mechanism configured to transfer a rotational force applied to the drive portion of the drive shaft through the angled tip portion to the drive end of the drive shaft. Disclosed screwdrivers may include an elastic retaining clip configured to have a bone screw securely attached therein at a clipping force and progressively release the bone screw therein at an extraction force. Disclosed screwdrivers may include at least one spring contacting the elastic retaining clip and the angled tip portion that is configured to facilitate the progressive release of the bone screw.

Various articulating tools for endoscopic placement of fasteners are disclosed. The tool can comprise a multi-angle articulating screwdriver. The tool can have an elongate shaft with an articulating driver head at a distal end. The tool can rotate the articulating driver head to drive fasteners, such as screws, to a surgical site. The articulating driver head can articulate with respect to a longitudinal axis of the elongate shaft to enable the fastener to be driven at various angle. The tool can be coupled to a powered handpiece power and can transmit torque from the handpiece to the driver head.

An extensive shaft assembly includes a casing, an extensive shaft, a sensor, a warning apparatus, and a connecting apparatus. The extensive shaft extends throughout the casing. The sensor is connected to the extensive shaft. The warning apparatus includes an LED module and a light-guiding ring. The light-guiding ring includes a slit. The LED module is electrically connected to the sensor and located in the slit of the LED module. The connecting apparatus connects the light-guiding ring to the casing so that an external annular portion of the light-guiding ring is visible through a gap between the casing and the connecting apparatus.

Position indicator tools systems and methods for use with an elongated adapter are disclosed. Tools are configurable to engage the distal end of the elongated adapter include a first member wherein the first member has a distal end and two projection elements positioned in a plane and a channel between the projection elements further wherein at least one of the first members has a notch at a distal end on a channel-facing side, a positioning member formed integrally with the first member wherein the positioning member has a linear marker on a first side, an angled marker on a second side, and a rocker positioned between the angled marker and the channel.
