Self-Retaining Quick-Coupling Screwdriver Set for Bone Screw Insertion

It means the screwdriver shafts attach to and release from the handle through a standardized push-pull interface, without rotation or tools. In surgery, this allows the scrub team or surgeon to exchange shaft sizes or tip types rapidly, reducing instrument change time and maintaining surgical rhyth.

Yes, the set is commonly configured with an AO quick-coupling interface, which is widely used in orthopedic instrument systems. This allows the shafts and handles to be interoperable with existing AO-compatible components in the hospital tray, subject to dimensional confirmation.

A self-retaining shaft has a mechanism at the tip that grips the screw head (or the screw recess) so the screw stays attached to the driver during transfer from the back table to the surgical site. This reduces the risk of screw drop and helps guide the screw into the plate hole or bone.

A standard configuration includes one or more quick-coupling handles (T-handle, straight handle, or ratchet handle) and a selection of self-retaining screwdriver shafts in various HEX or Torx tip sizes. The exact contents can be customized according to the screw system and surgical specialty.

Shafts and handles are typically made of medical-grade stainless steel. The set is reusable and autoclavable; it is supplied non-sterile and must be cleaned, disinfected, and sterilized before each use according to facility protocols..
