Patent number: 9662159Abstract: 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.Type: GrantFiled: October 10, 2014Date of Patent: May 30, 2017Assignee: Stryker European Holdings I, LLCInventors: Klaus Dorawa, Manuel Schwager, Marcel Aeschlimann, Philipp Seiler

Patent number: 9301790Abstract: A device and method for fixation of bone fractures has a bone screw comprising a shank with a threaded end portion, on the outer surface. The screw has a through bore with two bore portions differing in diameter. A step in the diameter is formed between these bore portions and is located within the end of the screw having the thread. This step in diameter can support a metal insert which in turn supports a polymer pin when the latter if pressurized with a sonotrode in the bone screw. Together with an applied ultrasonic vibration the pressure fluidizes the polymer pin and presses the material through holes configured in the wall of the bone screw and into surrounding bone.Type: GrantFiled: August 28, 2013Date of Patent: April 5, 2016Assignees: Woodwelding AG, Stryker European Holdings I, LLCInventors: Klaus Dorawa, Manuel Schwager, Christopher Rast, Marcel Aeschlimann, Philipp Seiler

Publication number: 20080269768Abstract: A screw holding device has a screw engaging part and a fixation sleeve. The screw for use with the screw holding device has a head and a shaft. The head of the bone screw has a recess and a notch. The screw engaging part has two halves with a hook formed on each half. The hook is shaped to fit in the notch. A fixation sleeve slides over the screw engaging part. When the fixation sleeve is pulled in proximal direction, the two halves of the screw engaging part are able to flex easily towards each other and thereby are insertable in the recess. When the fixation sleeve is moved towards the distal end of the screw engaging part, the two halves of the screw engaging part are prevented from flexing towards each other and thereby rigidly lock the screw and the screw engaging part together.Type: ApplicationFiled: April 10, 2008Publication date: October 30, 2008Applicant: Stryker Trauma SAInventors: Manuel Schwager, Klaus Dorawa

Publication number: 20080109008Abstract: An implantation device and method for applying the same has an implantation device for implantation in a target structure such as a bone. The implantation device comprises a shaft region, wherein the shaft region has at least one protrusion. The protrusion comprises a material which is modifiable by using mechanical energy. In particular, the modifiable material may be liquefiable and/or shearable by the mechanical energy. Preferably, the material may be adapted in such a way that the modifications may be achievable by a mechanical energy input which does not destroy human tissue.Type: ApplicationFiled: November 21, 2006Publication date: May 8, 2008Applicant: Stryker Trauma GmbHInventors: Manuel Schwager, Phillip Henry, Nils Zander
