A flexible surgical screw driver comprises a rotatable handle member, a shaft member and a flexible member. The handle member is configured with a first coupling means and the shaft member with a second coupling means. These first and second coupling means are configured to cooperate such that the handle member and the shaft member are angularly displaceable relative to each other and such that said handle member and said shaft member are non-rotatably coupled to each other for driving a screw with rotation transmitted from the handle member. The flexible member is configured to connect the handle member and the shaft member to each other and hold said handle member and said shaft member together such that the longitudinal axes thereof are substantially aligned and such that angular displacement of the handle member and the shaft member relative to each other such that the longitudinal axes thereof are misaligned, can be performed against the action of said flexible member.

A guide wire control device for advancing a guide wire into a body or a portion of the body, comprises a handle member (), a lever () and a spring means (). The spring means () holds the lever () relative to the handle member () such that the longitudinal axis of a through-hole () in the lever () is misaligned with the longitudinal axis of an elongate passage () in the handle member () for locking the guide wire control device to a guide wire () extending through said elongate passage and said through-hole. Pivotal movement of the lever () brings the longitudinal axis of the through-hole () into alignment or substantial alignment with the longitudinal axis of the elongate passage () for release of the guide wire (). Pivotal movement of the lever () also brings the longitudinal axis of the through-hole () into renewed misalignment with the longitudinal axis of the elongate passage () for clamping of the guide wire ().

Guide wire control device

The present invention relates to an intramedullary nail for proximal femoral fractures. The intramedullary nail comprises an elongate body () with a longitudinal bore (). The elongate body () includes a proximal portion () with an oblique transverse bore () for a proximal locking member and a distal portion () with at least one transverse bore () for a distal locking member. An inlet end of the oblique transverse bore () is configured as a recess () with a recessed surface (). The recessed surface () is composed of recessed lateral surface portions () and a recessed proximal as well as a recessed distal surface portion (andrespectively). Each of the recessed lateral surface portions () is configured with at least one protuberance () for preventing or reducing the risk for misalignment of e.g. a reamer and, if misalignment occurs, this will not affect critical parts of the intramedullary nail.

The rod coupler according to the present invention comprises two clamping jaws and locking means for locking said clamping jaws against one another. Each clamping jaw comprises an outside surface and a clamping surface, the latter providing at least a first and a second groove. Each groove runs laterally from a different part of the outside surface extending into the rod coupler, wherein longitudinal axis of the first groove and the second groove include an angle that is equal to or less than 160 degrees. Opposing grooves form an aperture. The apertures are adapted for receiving a rod if the locking means is released. Clamping jaws that are locked by the locking means clamp the rods received in said apertures.

A punching device for preparing a recess in a bone has a punching tool usable for such a punching device. An implant usable with the punching tool is provided and a method for preparing a recess in a bone are disclosed. The punching device comprises an ultrasonic sonotrode and a punching tool which is fixable to the sonotrode at its proximal extremity. At its distal extremity, the punching tool has a thin-walled portion having a non-rotational symmetric cross-section. By ultrasonic vibration of the punching tool, the thin-walled portion can be forced into a bone thereby preparing a recess of which is not rotationally symmetric. Subsequently, an implant can be held in such recess. Due to its lack of rotational symmetry, the implant may absorb rotational forces around its longitudinal axis.

Device and method for preparing a recess in a bone

A screw for fixation of, for example, a fracture having a hollow shaft, a first outer thread and radial openings at its distal end, and a second outer thread and an inner engagement portion at its proximal end. The second outer thread is adapted to engage with a tissue protection sleeve. The inner engagement portion is adapted to fit to a driving end of a driving tool. By way of this, forces in axial or radial direction may be applied to the screw by the sleeve, and forces in rotational direction may be applied by the driving tool. Therefore, the screw can be installed accurately at the intended site in an object.

An ultrasonic handpiece is used for augmenting a bone screw. The handpieces comprise a housing, an ultrasonic converter shiftingly accommodated in the housing, and a sonotrode connected to one end of the ultrasonic converter. The sonotrode protrudes from the housing into the bone screw. An adjuster wheel is adjustably connected to the housing. A spring is provided the ends of which are supported by the ultrasonic converter and the adjuster wheel, respectively. The ultrasonic converter is preloaded in the direction away from the adjuster wheel by setting the adjuster wheel, thereby the sonotrode is urged with a selected force into the bone screw and the augmentation material is pressed out of the bone screw and into the bone.
