Abstract
An endoscopic or laparoscopic biopsy forceps instrument is provided which includes a flexible tubular member having proximal and distal ends, a biopsy jaw assembly at the distal end of the tubular member, an actuation assembly to operate the jaw assembly between open and closed positions, and a control assembly to deflect the biopsy jaw assembly relative to a lumen through which the instrument extends and to rotate the jaw assembly about the longitudinal axis of the instrument.
Claims24
A biopsy forceps instrument having a longitudinal axis, comprising:
- a) an actuation handle having a stationary member and a movable member movable relative to said stationary member;
- b) a rotation control assembly coupled to a distal portion of said actuation handle;
- c) a tubular member having a proximal end and a distal end, said proximal end of said tubular member being coupled to a distal portion of said rotation control handle;
- d) a jaw assembly coupled to said distal end of said tubular member;
- and
- e) an actuation wire having a proximal end and a distal end, and coupled between said movable member and said jaw assembly,
- wherein said jaw assembly includes a proximal portion and a distal portion spring-biased relative to the proximal portion and thereby adapted to be deflected at a predetermined angle relative to the longitudinal axis of said biopsy forceps instrument and define a predetermined radial extension of said distal portion of said jaw assembly.
A biopsy forceps instrument having a longitudinal axis, comprising:
- a) an elongate flexible shaft having a proximal end and a distal end;
- b) a handle coupled to said proximal end of said shaft;
- and
- c) a jaw assembly coupled to said distal end of said shaft, said jaw assembly including jaws which are radially spring-biased relative to said shaft and thereby adapted to be deflected at a predetermined angle relative to the longitudinal axis of said biopsy forceps instrument so as to define a predetermined radial extension of jaws of said jaw assembly relative to said shaft.
A biopsy forceps instrument having a longitudinal axis, comprising:
- a) a jaw assembly including jaws;
- b) a rotation control assembly for rotating said jaws;
- c) an actuation handle for moving said jaws between open and closed positions;
- d) a first flexible tubular member, wherein said actuation handle and said rotation control assembly are coupled to and spaced apart by said first tubular member;
- and
- e) a second flexible tubular member, wherein said rotation control assembly and said jaw assembly are coupled to and spaced apart by said second tubular member.
A surgical biopsy forceps instrument having a longitudinal axis, comprising:
- a) a biopsy forceps jaw assembly;
- b) a plurality of control elements each having a proximal end and a distal end, said distal ends of said control elements being coupled to said jaw assembly;
- and
- c) control means for rotating said plurality of control elements relative to said actuation means about the longitudinal axis and also for maneuvering said plurality of control elements in a direction other than rotation about the longitudinal axis.
