A surgical apparatus comprising: a mechanism that is configured to perform an operational motion of the surgical apparatus; and at least one transformation member having an original shape and a deformed shape, the at least one transformation member connecting the mechanism together, when the at least one transformation member is in the deformed shape so that the mechanism is capable of performing the operational motion; and wherein after the transformation member is subject a transition temperature, the at least one transformation member changes from the deformed shape to the original shape and disengages a portion of the mechanism so that the mechanism is prevented from performing the operational motion.

An apparatus for releasably holding a surgical tool having a body, the body having a longitudinal axis, a monolithic construction, and a shape apportioned to be grasped by a human hand, with body further having a tool engaging portion, a hand receiving portion, and a button pressing portion. A longitudinal bore is disposed along the longitudinal axis of the body, and on one end. A transverse bore is disposed through the body into the longitudinal bore, with the transverse bore disposed such that the longitudinal axis of the transverse bore intersects the longitudinal axis of the longitudinal bore. A button disposed on and pivotably attached at a resilient member to the button pressing portion of the exterior of the body, with the button being proximal to the tool engaging portion. The button has a button bore and a boss extending from the button bore into the transverse bore which is alignable with the longitudinal bore. The button is disposed on the body to be thumb pressable, the button suitable for selectively engaging a corresponding groove on surgical tool.

A spinal plate bender includes an actuation assembly, a collet, and a head portion. The actuation assembly includes a housing, a lever pivotably coupled to the housing, a linkage pivotably coupled to the lever, and an actuation shaft operatively coupled with the linkage. The lever is transitionable between a neutral position and an actuated position, which imparts axial displacement to the actuation shaft. The collet includes a proximal section, a sleeve section extending distally from the proximal section, and a coupling section extending distally from the sleeve section. The head portion is configured to support a spinal plate. The head portion includes an anvil portion coupled to a distal end portion of the actuation shaft. The anvil portion is configured to engage a spinal plate to cause bending of a spinal plate supported in the head portion.

Various implementations include an external fixation device for posterior pelvic compression that allows a pin engaged into one iliac bone to be pivoted relative to the pin engaged into the other iliac bone, allowing compression of the iliac bones toward each other and the interposed sacrum and for the relative positions of the pins to be held fixed relative to each other after the compression is set. The pin to be pivoted is engaged into the iliac bone closest to the source of the injury. And, the pins and bars of the fixation device are anteriorly coupled together, which gives the patient greater transportability, as well as maintenance of reduction that will assist in the definitive surgical intervention.

Devices and methods for an autovance intraosseous device. The autovance intraosseous device can include a trigger activated system or pressure activated system that causes a needle to advance distally for a predetermined distance. The predetermined distance ensures a needle tip extends through the bone cortex, to access the medullary cavity, without penetrating a far wall of the medullary cavity. The advancement can be driven by a spring based system or an electric motor.

An extension conduit for use with a system for aspirating thrombus includes a passageway extending between a distal end and a proximal end of the extension conduit, and a combined hydraulic and electrical control carried on the extension conduit and configured to be activated by a user to activate an electric switch while opening a valve to allow flow through the passageway.

A powered handle assembly includes a motor assembly, a rack, a spur gear, and a manual retract mechanism. The spur gear is movable from a position engaged with the motor assembly and the rack to a positioned disengaged from the motor assembly and engaged with the rack to facilitate manual retraction of the rack.

Disclosed herein is a tissue engaging surgical tool that is configured to selectively hold or grasp a portion of tissue with a suction cup or flexible end portion. The device is configured to increase or decrease pressure between the flexible end portion and tissue that the end portion is held against, thereby creating a releasable suction or vacuum force.

An electrosurgical device having first and second poles; blade electrode with a metal shim having two opposing faces and one or more facets, a nonconductive coating which covers at least the faces and a portion of the facets of the metal shim, while a distal portion of the one or more facets remains uncovered by the nonconductive coating; a lateral electrode comprised of a broad shim having one or more conductive faces and is placed parallel to the blade electrode so that at least one of the one or more conductive faces is exposed and a distal end of the blade electrode protrudes from the lateral electrode; the lateral electrode is fixed stationary relative to the blade electrode; the nonconductive coating insulates the blade electrode from the lateral electrode; and the first pole is connected to the blade electrode and the second pole is connected to the lateral electrode.

A universal wire driver attachment comprises a driveshaft forming a lumen extending along a longitudinal axis. The driveshaft forms a plurality of channels extending perpendicularly from the longitudinal axis. The attachment further comprises a plurality of primary jaws movably disposed at least partially within the channels. The primary jaws comprise a plurality of wire gripping surfaces facing the longitudinal axis and configured to grip the surgical wire. The primary jaws cooperate with the channels such that the primary jaws are constrained from moving in an axial direction along the longitudinal axis. The primary jaws are capable of moving outward from the longitudinal axis when the surgical wire is inserted between the primary jaws, and the primary jaws are capable of being urged inward toward the longitudinal axis by the securing mechanism to increase a grip force on the surgical wire.
