Abstract
A method and a device is described. The probe device is a leading probe for surgical procedures which includes both instrument access and illumination. The leading probe device includes an annular arrangement of a plurality of light transmission fibers about a central instrument-receiving working channel. The leading probe may be fixed on the outer wall of the eye by a notched footplate with suitable suture material. Alternatively, the present invention device may have an appropriate adhesive member for securing the leading probe at the surface of the eyeball.
Claims10
A probe device for use in medical procedures in an eye, comprising:
- a generally cylindrical main wall;
- a foot plate about an intermediate portion of said main wall;
- said foot plate including means for abutting an outer surface of said eye;
- a generally cylindrical working channel coaxial with said main wall;
- said working channel including a probe leading end;
- said probe leading end including means for enabling entry of said probe leading end through an eyeball wall into said eye;
- said working channel permitting the passage of at least one of a surgical instrument or an optical device therethrough from outside said eye though said probe leading end to an interior of said eye;
- means for permitting plugging of an outer end of said working channel, whereby leakage of a fluid from an interior of said eye is prevented;
- a side tube joining said main wall at an angle to an axis thereof;
- a bundle of optical fibers passing through said side tube into an interior of said main wall outside said working channel;
- said bundle of optical fibers passing through said side tube from outside said side tube into said main wall;
- said bundle of optical fibers terminating in a pattern at said probe leading end;
- and
- said pattern being an annulus surrounding said working channel.
