Abstract
A microsurgical laser probe is provided with a distal end portion of an optic fiber that projects from a tubular sleeve of the probe and can be caused to bend relative to the probe sleeve by manual manipulation of a mechanism on a handle of the probe.
Claims20
A surgical instrument comprising:
- an instrument handle;
- a tubular sleeve projecting from the instrument handle;
- an optic fiber extending through the handle and the sleeve to a distal end portion that projects from the sleeve, the distal end portion of the optic fiber having an adjustable bend therein;
- the handle has a mechanism that is connected to the sleeve and selectively moves the sleeve between pushed forward and pulled back positions of the sleeve relative to the handle;
- and,
- the sleeve is a rigid tube that projects from the handle and the distal end portion of the optic fiber has a preformed bend that is straightened when the sleeve is moved to the pushed forward position causing the distal end portion to be retracted into the tube of the sleeve and the preformed bend bends when the sleeve is moved to the pulled back position causing the distal end portion to be extended from the tube of the sleeve.

A surgical instrument comprising:
- an instrument handle;
- a tubular sleeve projecting from the handle;
- an optic fiber extending through the handle and the sleeve to a distal end portion of the fiber;
- a mechanism on the handle and connected to the sleeve to selectively move the sleeve between a pushed forward position of the sleeve where the sleeve projects a first distance from the handle and the optic fiber distal end portion is retracted into the sleeve and a pulled back position of the sleeve where the sleeve projects a second distance from the handle that is less than the first distance and the optic fiber distal end portion is extended from the sleeve;
- and
- the sleeve is a rigid tube that projects from the handle and the distal end portion of the optic fiber has a preformed bend that is straightened when the distal end portion is retracted into the tube of the sleeve and bends when the distal end portion is extended from the tube of the sleeve.
