Positioning device for securing an intramedullary nail in a long bone
11350951 · 2022-06-07 · ·

The present invention relates to a positioning device (100, 100′, 100″) for securing an intramedullary nail (19) in a long bone, said positioning device comprising a guide bow (1), with an adjusting device (3) and a sleeve guide (2), wherein the adjusting device (3) has a targeting device (5); and wherein the targeting device (5) is designed to receive a locking device (21) or an instrument (23) for acting on the locking device (21); and wherein the sleeve guide (2) has a sleeve (7), which sleeve (7) is mounted in the sleeve guide (2) such that it can be rotated and/or slid relative to the sleeve guide (2); and wherein the sleeve (7) has a longitudinal through-opening for receiving a guiding device therein.

Surgical guidance device and system for insertion thereof

Briefly, the invention relates to a surgical tool and method for forming a pilot bore by inserting a guide wire into bone. More particularly, the device includes a cannulated hand grip and driving tool used for the rotation of a pedicle screw into bone. The rear portion of the hand grip includes a slide assembly that is suited to grip a guide wire. The slide assembly includes a user adjustable stop to control the sliding movement of the guide wire. The rear surface of the slide assembly is constructed to be impacted with a hammer or similar device, whereby the stop prevents the guide wire from penetrating the bone further than desired. Should it be desired that the guide wire be retracted, a screw jack is included to allow the guide wire to be precisely retracted.

Cannulated compression device
11344343 · 2022-05-31 ·

The cannulated compression device creates fixation and compression across its tang housing, thus stabilizing and closing a bone fracture during placement. After insertion of the cannulated compression device, tangs are extended outward from the tang housing, locking the tang housing with respect to both rotational and axial movement. A compression nut is then threaded onto the proximal end of the tang housing. The nut has two sets of threads: a first set of threads interfaces with the tang housing, a second set of threads interfaces with the bone. By using different pitches, the amount of linear movement for the first set of threads and second set of threads is different.
