Abstract
A small gauge surgical instrument is shown with advantages such as diminished “play” at the tip. A surgical instrument assembly is also shown with support along a length of the instrument that can be selected by the surgeon. Devices and method described provide adjustability of the instrument without protruding into a gripping surface of the instrument.
Claims21
An ophthalmologic instrument, comprising:
- a base unit having a lateral gripping surface;
- a small diameter instrument extending from the base unit, the small diameter instrument having a length;
- a support frame slidably coupled to the small diameter instrument along the length, and free to move along the length;
- a biasing device to urge the support frame towards an extended location along the length of the small diameter instrument;
- and
- one or more supply lines routed through an interior of the base unit to the small diameter instrument, wherein the support frame is spaced apart from the one or more supply lines, and both the support frame and the one or more supply lines are contained laterally within the lateral gripping surface as they pass through the interior of the base unit.

- a support frame slidably coupled to the small diameter instrument along the length, and free to move along the length;
- a biasing device to urge the support frame towards an extended location along the length of the small diameter instrument, wherein a biasing force preload amount of the biasing device is adjustable;
- wherein a distal portion of the support frame is adapted to make contact with a patient's eye and wherein a biasing force of the biasing device may be overcome by pressing the distal portion of the support frame against the patient's eye, to extend the small diameter instrument into a posterior portion of the patient's eye when in use.
