Publication number: 20190321058Abstract: Systems and methods for preparing a bone for a surgical procedure are provided. In general, the described techniques use a surgical guide device including a cannula having first and second parallel elongate channels adjacent to one another, and first and second elongate sleeves configured to be removably and replaceably received in the first and second channels, respectively. The first sleeve has a plurality of openings formed therein, each being in communication with a respective wire-receiving lumen extending through the first sleeve. Each of the openings defines a different offset distance between the wire-receiving lumen in communication with that opening and a wire-receiving lumen extending through the second sleeve. The surgical device can be manipulated so as to define positions of first and second openings in a bone, such as a glenoid or other bone, to receive bone screws or other elements for attaching a bone graft to the bone.Type: ApplicationFiled: June 5, 2019Publication date: October 24, 2019Applicant: Synthes GmbHInventors: Nicolas Bouduban, Patrick Burki, Laurent Lafosse

Publication number: 20130340553Abstract: Systems and apparatus for reliably sealing a surgical device are disclosed herein. Specifically, a surgical device including a drive shaft tube that is coupled to a drive shaft is disclosed. Because the drive shaft tube is coupled to the drive shaft, the drive shaft tube rotates at the same rotational speed as the drive shaft, which is less than the rotational speed of a cannulated motor shaft. The drive shaft tube can extend through the cannulated motor shaft. In addition, a sealing member can be provided to seal between the drive shaft tube (which rotates slowly) and the motor instead of between the motor shaft (which rotates more quickly) and the motor. The sealing member can be provided in a gap defined between an outer surface of a portion of the drive shaft tube extending beyond the cannulated motor shaft and the motor.Type: ApplicationFiled: June 26, 2012Publication date: December 26, 2013Applicants: SYNTHES USA, LLC, SYNTHES GMBHInventors: Urs Dürrenberger, Martin Münch, Nils Schmuckli
