Abstract
In one embodiment, a surgical instrument is provided for grasping spherical implants. The surgical instrument includes a first lever arm having distal and proximate ends, as well as a second lever arm having distal and proximate ends. A first concave grasping cup is disposed at the distal end of the first lever arm. A second concave grasping cup is disposed at the distal end of the second lever arm. The first grasping cup and the second grasping cup are of differing sizes to enable the instrument to securely grasp spherical implants of a plurality of differing sizes.
Claims18
A surgical instrument for grasping spherical implants comprising:
- a first lever arm having distal and proximate ends;
- a second lever arm having distal and proximate ends;
- a first grasping cup disposed at the distal end of the first lever arm, the first grasping cup having a concave interior surface shaped substantially as a portion of a first hemisphere;
- and
- a second grasping cup disposed at the distal end of the second lever arm, the second grasping cup having a concave interior surface shaped substantially as a portion of a second hemisphere;
- wherein the first grasping cup and the second grasping cup are of differing sizes to enable grasping of spherical implants of a plurality of differing sizes.
A surgical instrument for grasping spherical implants comprising:
- a first grasping cup having a concave interior surface shaped substantially as a portion of a first hemisphere, the surface establishing an enclosure of a first diameter approximately equal to the diameter of a smallest spherical implant of a range of spherical implants supported by the instrument;
- and
- a second grasping cup having a concave interior surface shaped substantially as a portion of a second hemisphere, the surface establishing an enclosure of a second diameter approximately equal to the diameter of a largest spherical implant of a range of spherical implants supported by the instrument.
