Push-off driver and method for inserting bone screws

A method and device for inserting screws into a patient, such that when the device is removed the device does not stick to the screw. The device, being a push-off driver, may have a handle, an inner driver, and a threaded driver sleeve having a button mechanism and a plurality of spheres, and an inner sleeve. The method includes the steps of assembling a push-off driver attaching a bone screw to the push-off driver inserting the bone screw and detaching the bone screw from the driver by unthreading the threaded driver sleeve from the polyaxial screw which causes the spheres in the recess of the inner driver to back up against the start of the recess and causing the threaded driver sleeve to push-off the polyaxial screw from the inner driver.

Fastener staging and placement system and method of using the same
09707667 · 2017-07-18 · ·

A fastener staging and placement system comprising a staging member capable of temporarily attaching to structures and storing a plurality of ring type fasteners, and a placement member with a means for gripping and removing one or more fasteners to and from the staging member. The staging member comprises a removable and substantially vertically oriented dowel, configured to present a series of ordered sets of fasteners to the placement member, and an attachment means that may be removably attached to various structures. The placement member comprises two or more gripping arms that are configured to flex and exert pressure on at least one fastener thereby securing an ordered set of fasteners.

Surgical fastener with predetermined resorption rate

A resorbable screw fastener and a method of firing with an applicator capable of applying a surgical fastener to tissue in order to form tissue connection to secure objects to tissue, the fastener including a body portion having a helical thread, a head portion disposed at the proximal end of the body portion. The resorbable screw fastener is 100% resorbed in vivo during a period of time ranging from about 14 days to about one year after implantation.
