Endoscopic instrument for use in medical device to examine cavities in inner body of human, has projection device for converting light produced by light source into projection light that is discharged from distal end to produce projection

摘要

The instrument (1) has a shaft (3) with a proximate end (5) and a distal end (7), and a light source (13) i.e. laser light source, arranged at the proximate end of the shaft for producing light. A projection device (15) converts the light produced by the light source into projection light that is discharged from the distal end of the shaft for producing a projection, where the light produced by the light source is guided to the projection device. A combining optic is arranged between the light source and a micro mirror of a reflectance device of the projection device. An independent claim is also included for a medical device comprising a tracking system for determining a position of an endoscopic instrument.
