1. A biopsy forcep comprising:
- a. a flexible catheter having a distal and proximal end, said distal end being designed so as to be placed within a patient'"'"'s body to obtain a biopsy sample and said proximal end being designed so as to be located outside of said patient'"'"'s body and including means for controlling components of said biopsy catheter located at about the distal end of said flexible catheter;
b. a forcep cup assembly attached to the distal end of said flexible catheter;
c. a first hinge means attached to said flexible catheter placed proximally in relation to said forcep cup assembly, said first hinge means controlling the opening and closing of said forcep cup assembly and;
d. a second hinge means attached to said flexible catheter placed proximally in relation to said first hinge means and said forcep cup assembly, said second hinge means controlling the articulation of the portion of said biopsy forcep including said forcep cup assembly and first hinge means, said second hinge means and resultant articulation being controllable from the proximal end of said flexible catheter.

Abstract
This invention relates to a biopsy forcep for use in a flexible fiberoptic bronchoscope. More particularly, this invention is directed to a biopsy forcep having an increased range of operability when used in conjunction with the flexible fiberoptic bronchoscope when obtaining tissue samples such as smooth growths in the trachea or main stem bronchii.

7. A biopsy forcep comprising:
-
flexible catheter terminating in a distal and proximal end, defining an interior cavity therebetween, a forcep cup assembly located at said distal end and a forcep controller at said proximal end, said catheter surrounding a first and second wire; said first wire traversing the entire length of the interior cavity of said catheter; said first wire being attached at its distal end to a first hinge means; said first hinge means being connected to said forcep cup assembly; said first wire being attached at its proximal end to a first control means on said forcep controller, whereby moving said first control means on said forcep controller acts to operate said first hinge means thereby opening or closing said forcep cup assembly; and said second wire traversing the entire length of the interior cavity of said flexible catheter; said second wire attached at its distal end to a second hinge means; said second hinge means being connected between said first hinge means and said flexible catheter; said second wire being attached at its proximal end to a second control means on said forcep controller, whereby moving said second control means on said forcep controller acts to operate said second hinge means thereby articulating said forcep cup assembly towards or away from the longitudinal axis of the proximal portion of said second hinge means. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
