Abstract
A method of extracting biopsy cells from a breast uses an endoscopic instrument having a distal end that is substantially needle like, a working channel, a light source and a lens. The instrument can be coupled to an apparatus for viewing an image including depth of field viewing. The instrument is inserted into a nipple of a breast and liquid is ejected from the distal end. Reverse pressure is applied so that the liquid and biopsy cells are retrieved into the instrument. The cells are then extracted from the breast.
Claims14
A method of extracting biopsy cells from a body using an endoscopic instrument having a distal end that is sub statially needle like, said method comprising the steps of:
- (a) inserting said instrument into a nipple of a breast;
- (b) causing liquid to be ejected from the distal end of said instrument;
- (c) causing reverse pressure to form at the distal end of such instrument so that said liquid and biopsy cells are retrieved into said instrument;
- and
- (d) extracting said cells from said breast,
- wherein the endoscopic instrument includes a guide having a working channel, a light source and a lens.
A method of extracting biopsy cells from a body using an endoscopic instrument having a distal end that is substantially needle like, said method comprising the steps of:
- (a) inserting said instrument into a nipple of a breast;
- (b) causing liquid to be ejected from the distal end of said instrument;
- (c) causing reverse pressure to form at the distal end of such instrument so that said liquid and biopsy cells are retrieved into said instrument;
- and
- (d) extracting said cells from said breast,
- wherein the endoscopic instrument includes a guide having a working channel, a light source and a lens, said guide coupled to means for receiving a medical instrument, to means for irrigating and to means for supplying image information image, and
- wherein the endoscopic instrument also includes a video camera coupled to a video monitor.
A method of extracting biopsy cells from a body using an endoscopic instrument having a distal end that is substantially needle like, said method comprising the steps of:
- (a) inserting said instrument into a nipple of a breast;
- (b) causing liquid to be ejected from the distal end of said instrument;
- (c) causing reverse pressure to form at the distal end of such instrument so that said liquid and biopsy cells are retrieved into said instrument;
- and
- (d) extracting said cells from said breast,
- wherein the endoscopic instrument is coupled to an apparatus for depth of field viewing, said apparatus including:
- a transparent screen for positioning between a flat image and a viewer, said transparent screen including a plurality of optical elements formed in said screen;
- and
- an aspherical lens for positioning between said screen and a viewer, said lens being curved across its width which curvature is defined by at least two radii.
