Abstract
A direction changing device for a bioptic instrument having a protrusion provided at the top opening edge of an insertion passage into which a bioptic member or the like of an endoscope is inserted. The top opening edge is positioned in the vicinity of an objective lens of the endoscope or before the objective lens. The protrusion serves as a fulcrum to bend a pipe of bioptic instrument. A depressing member is located adjacent the protrusion to deflect an element of the instrument over the protrusion. The inserted member may be a device for taking samples or a fluid injection system. The instrument body may have a hood attached to the outer end with a direction changing protrusion on it. The hood may be rotatable relative to the instrument body. Deflection of the sample device of fluid stream is accomplished by positioning the deflection member relative to the passage in the instrument. A valve may be employed to seal the passage from contaminating elements. The deflecting member may be stationary or pivoted on the body or the hood and can be remotely actuated. It may be flexible or solid and be annular or a protrusion. The deflecting member can also positively engage the sample taking device and it may be arranged for pivotal movement.
