Retainer, combination of a packaging and a retainer, adapter and a retainer with a support structure for a surgical device

Abstract

An adapter for a surgical device which comprises a first end, a second end, and a longitudinal axis. The adapter comprises a surgical section provided at the second end for connecting to a surgical device, an engagement section provided at the first end adapted to engage an insertion device, and a support section for connecting to a retainer. The surgical section comprises, on a side of the first end, a force or torque transmission means for the surgical device and, on the first end, an attachment element for a removable connection to the implant is placed. The support section comprises an at least partially non-circular shape such that the adapter is removable by rotating the adapter around its longitudinal axis.

         47 . The adapter according to  claim 44 , wherein the attachment element comprises at least two spring elements. 
     
     
         48 . The adapter according to  claim 47 , wherein the at least two spring elements each comprising at least one pre-defined contact section for contact with the surgical device. 
     
     
         49 . The adapter according to  claim 48 , wherein the at least one contact section has a cross-section along the longitudinal axis of the adapter with a round shape. 
     
     
         50 . The adapter according to  claim 44 , wherein the adapter comprises a predefined breaking point between the engagement section and the support section. 
     
     
         51 . The adapter according to  claim 44 , wherein the force or torque transmission means include a spline shaft. 
     
     
         52 . The adapter according to  claim 44 , wherein at least one marking is provided on the side of the first end. 
     
     
         53 . The adapter according to  claim 44 , wherein the engagement section is a spline hub. 
     
     
         54 . The adapter according to  claim 44 , wherein the adapter is formed to include a cavity, which extends along the longitudinal axis, in a cross-section of the force or torque transmission means. 
     
     
         55 . The adapter according to  claim 53 , wherein the at least one marking is a notch or projection, the at least one notch or projection extends along the longitudinal axis of the adapter, and a circumferential position of the at least one marking corresponds to a circumferential position of at least one lobe of the spline shaft.
