A modular system for treating a bone includes a main body including a channel extending therethrough. A distal end includes a driving feature sized and shaped to engage a corresponding driving structure of one of first and second bone screws. The system also includes an inner shaft sized and shaped to be inserted into the channel and including a distal end including a retaining feature for engaging a corresponding retaining structure extending within a recess at a proximal end of the first screw. Furthermore, the system includes an outer shaft extending longitudinally and including a channel extending therethrough. The channel of the outer shaft is sized and shaped to slidably receive the main body therein and including a retaining feature extending along a distal end thereof. The retaining feature of the outer shaft engages a retaining structure extending along an exterior surface of the second screw.

Modular retaining screwdriver

The invention relates to a system and method for driving orthopedic bone screws. In one aspect the driver includes a powered driving rod that is configured to releasably couple with a recess in a bone screw via a threaded system for coupling and uncoupling the screw from the driving rod.

Powered retaining screwdriver

A driver for engaging an endcap of an intramedullary nail. The driver includes a handle extending along a longitudinal axis of the driver from a proximal end to a distal end. The handle having a handle channel extending longitudinally therethrough. The driver also includes a shaft extending through the handle channel from a proximal end to a distal end along the longitudinal axis. The shaft having a shaft channel extending longitudinally therethrough. The distal end of the shaft extends distally from the handle. The distal end of the shaft forms a driving element to be inserted into a head portion of the endcap. The driver further includes a retention pin slidably received in the shaft channel. The retention pin extends also extends along the longitudinal axis. The distal end of the retention pin is configured to reversibly lock the shaft to the head portion of the endcap.

Driver and system for threaded intramedullary nail retaining endcaps

A bone screw insertion device, comprises an outer sleeve extending from a proximal end to a distal end and including a channel extending therethrough and a driving member extending longitudinally through the channel of the outer sleeve from a proximal end to a distal end configured to engage a driving recess of a bone screw, the outer sleeve movable relative to the driving member between a first position in which the distal end of the outer sleeve extends over and covers a proximal portion of a bone screw engaged with the driving member, to a second position in which the distal end of the outer sleeve is longitudinally aligned with a proximal end of a bone screw engaged with the driving member.

Self-retaining screw and screwdriver

An endcap for engaging a proximal end of an intramedullary nail. The endcap includes a body extending from a first end to a second end and configured to engage a channel of an intramedullary nail. The endcap also includes a head portion at the first end of the body. The head portion includes a recess sized and shaped to receive a driving element of a drive shaft. The recess includes elastic tabs extending radially toward a central axis of the recess to engage and retain a driving element received therein.

A compression nut for treating a bone includes a head and a body extending longitudinally from the head to a free end. The body includes a first portion including an exterior surface tapering from the head toward a second portion. An exterior threading extends along an exterior surface of both the first portion and the second portion of the body. The nut also includes a channel extending longitudinally through the body. The channel includes an interior threaded extending along an interior surface of the channel configured to threadedly engage a portion of a locking screw therein.

Compression nut and a system for treating a bone

A compression nut for treating a bone includes a head and a body extending longitudinally from the head to a free end. The body includes an exterior threading along an exterior surface of a threaded portion of the body separated from the head via an unthreaded portion. The nut also includes a channel extending longitudinally through the body. The channel includes an interior threaded extending along an interior surface of the channel configured to threadedly engage an end of a locking screw received therein.

A bone screw extraction device includes a shaft extending longitudinally from a proximal end to a distal tip, a distal portion of the shaft including a tissue-receiving cavity extending proximally thereinto from the distal tip, the distal tip including a plurality of fingers configured to be received within a driving recess of a bone screw and a plurality of channels extending longitudinally along an exterior surface of the distal portion, each of the plurality of channels extending between adjacent ones of the plurality of fingers.

Screw extraction shaft

A nut for treating a bone includes a head and a body extending longitudinally from the head to a free end and including a channel extending longitudinally thereinto from the free end, the channel configured to engage an end of a bone screw, and an exterior threading extending about the body from an exterior surface thereof along an entire length thereof, an outer contour of the exterior threading defined via radially outermost edges of the exterior threading, a first portion of the outer contour adjacent the head portion having a smaller diameter than a second portion of the outer contour extending from the first portion to the free end of the body.

System and method for treating a bone

A screwdriver assembly includes a screwdriver shaft and an insert. The screwdriver shaft extends longitudinally from a proximal end to a distal end and having a longitudinal channel extending therethrough. The insert has a longitudinal shaft received within the longitudinal channel and a distal end extending distally relative to the distal end of the screwdriver shaft. The insert shaft is rotatable relative to the screwdriver shaft. The distal end of the insert is sized and shaped to engage a head of a screw. The distal end of the insert is disengaged from the screw head by rotating the insert relative to the screwdriver shaft.
