Abstract
An acetabular cup guide can include a distal end (11) shaped to allow removable connection to a surgical instrument (16), a proximal end including one or more contact surfaces (4, 5) shaped to conform to an acetabulum, and a central proximal-distal axis extending through the acetabular cup guide. At least one of the one or more contact surfaces can be configured such that it is deflectable towards the central proximal-distal axis in order to reduce an axial cross-section of the acetabular cup guide.
Claims20
An acetabular cup guide comprising:
- (a) a distal end which is shaped to allow removable connection to a surgical instrument,
- (b) a proximal end comprising one or more contact surfaces which are shaped to conform to an acetabulum, and
- (c) a central proximal-distal axis extending through the acetabular cup guide, wherein at least one of the one or more contact surfaces is deflectable towards the central proximal-distal axis in order to reduce an axial cross-section of the acetabular cup guide.
A method of inserting an acetabular cup guide into an acetabulum, the method comprising:
- releasably connecting a distal end of the acetabular cup guide to an insertion tool, the acetabular cup guide including one or more deflectable contact surfaces;
- deflecting at least one of the one or more deflectable contact surfaces of the acetabular cup guide towards a central proximal-distal axis of the acetabular cup guide;
- and
- inserting the acetabular cup guide into the acetabulum such that the one or more deflectable contact surfaces deflect away from the central proximal-distal axis and towards the acetabulum.
