If you have complex medical threads you need to gage, GSG can offer your the expertise you need. Various conventional split hexalobe driver devices exist for retaining and rotating locking caps, set screws, and bone screws used in orthopedic surgical procedures and the like. In use, the split 40 may be splayed open to create an interference fit between driver tip 12 and the socket 60 of screw 50 , thus securely retaining the screw 50 onto tip Patents, Trademarks, Copyright Law: A longitudinal split is defined through the tip from the distal end thereof and extends proximally into the driver tip.

The screw driver tip defines a hexalobe engagement feature at a distal end of the driver tip. US USB2 en Referring now to FIG.

Screwdriver Shaft, Hexalobe Drive T15, A-O Quick Coupling, Self Retaining, 100mm

Referring now specifically to FIG. A hexalobe screw driver for use with a screw head having a hexalobe socket. Thus, what is still needed in the art is an improved driver device that avoids this problem. Vote Promote or demote ideas.

The handle portion 12 may be integrally formed with, welded to, threadingly engaged with, or otherwise fixedly or removably coupled hedalobe the elongate shaft portion 14which may be a unitary structure or consist of several coupled components as illustrated. The medical field has some of the most complex threads in the manufacturing industry.

Arthrex – Driver Shaft, T10 Hexalobe, Cannulated – AR

Thus, there is a need for a screw driver that has a hexalobe tip that is retained within a low profile screw having a hexalobe head. Preferably, the elongate shaft portion 14 and the end portion 16 also share a common central axis, although again this is not a requirement.


It is desirable to maintain correct alignment between a screw driver and a screw. Review native language verification applications submitted by your peers.

Driver tip 12 includes a hexalobe engagement feature 20 defined at its distal end. Login or register free and only takes a hhexalobe minutes to participate in this question.

Once placed into nub socket 60nub 30 creates tighter axial alignment, maintaining the desired alignment between screw driver 10 and screw GSG offers design and build services for all your medical gaging needs. More particularly, the present invention relates to a hexalobe screw driver having a pilot nub and self-retaining tension that may be used for placing surgical implants. In one exemplary embodiment, the present invention provides a surgical driver device, including: The surgical driver device of claim 5wherein the first half of the two asymmetric halves of the screw engagement portion is substantially larger than the second half of the two asymmetric halves of the screw engagement portion.

View Ideas submitted by the community. A longitudinal split is defined through the tip from the distal end portion thereof and extending proximally into the driver tip.

Driver tip 12 includes a split 40 running longitudinally through the tip and proximally into the body of the screw driver One of the two asymmetric halves of the screw engagement portion is configured to deflect into the relief split when the two asymmetric halves of the screw engagement portion are disposed in a corresponding tool engagement recess of a screw.

The result is that driver 10 and screw 50 stay aligned, do not separate during driving force and screw 50 is held much tighter to tip The hexalobe engagement feature includes an hesalobe nub protruding distally beyond the distal end portion of the engagement feature.

All of these components may be made of a metal or other surgically compatible material. On the contrary, the invention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims. In the following descriptions, the present invention will be explained with reference to example embodiments thereof.

The present invention generally relates to a screw driver having a hexalobe tip. Bexalobe socket 60 creates greater holding depth in screw head 52without increasing the overall height of screw head However, these embodiments are not intended to limit the present invention to any specific example, embodiment, environment, applications or particular implementations described in these embodiments. The surgical driver device of claim 1wherein the elongate shaft portion comprises more than one component.
