Modular medical instrument and method of using same
First Claim
1. A modular medical instrument capable of being disassembled for cleaning and reassembled for reuse, said modular medical instrument comprising:
- an elongated guide member having a proximal end and a distal end and a channel extending from said proximal end to said distal end;
an inner actuation cable slidably disposed within said channel in said elongated guide member and having a proximal end and a distal end;
an instrument head assembly disposed at said distal end of said inner actuation cable and extending from said distal end of said elongated guide member; and
an actuator handle detachably coupled to said proximal end of said elongated guide member and detachably coupled to said proximal end of said inner actuation cable such that said actuator handle moves said inner actuation cable within said channel in said elongated guide member to actuate said instrument head assembly, wherein said actuator handle is capable of being detached and reattached to both said elongated guide member and said inner actuation cable.

Abstract
A modular medical instrument is used with an endoscope or other similar medical instrument to perform medical procedures, such as endoscopy, bronchoscopy, and laparoscopy. The modular medical instrument comprises an elongated instrument device, an optional port fitting detachably coupled to the instrument device, and an actuator handle detachably coupled to the port fitting. The instrument device includes an elongated guide member, an inner actuation cable slidably disposed within the guide member, and an instrument device head assembly disposed at a distal end of the guide member and actuation cable. The guide member preferably has a smooth outer surface to facilitate insertion within the instrument channel of an endoscope or similar medical device. In one example, the instrument device head assembly includes a grasping device, such as biopsy forceps. The biopsy forceps device includes first and second jaws pivotably coupled to a body member, which is detachably coupled to an adapter at the distal end of the guide member. The actuation cable includes first and second portions or wires extending through the body member and coupled to the respective jaws such that relative movement of the actuation cable with respect to the body member causes the jaws to open and close. Each of the components or sub-assemblies of the modular medical instrument are detachable for cleaning and/or replacement.

16. A forceps device for use with a modular medical instrument, said forceps device comprising:
-
a body member having a first end and a second end; first and second forceps jaws pivotably coupled to said first end of said body member, said first and second forceps jaws having respective first and second tangs; and an actuation cable having at least first and second wires wound together, wherein said first and second wires extend through said second end of said body member, wherein said first wire extends through said first tang of said first forceps jaw and said second wire extends through said second tang of said second forceps jaw, and wherein said first and second wires extend back through said second end of said body member to said actuation cable, wherein movement of said actuation cable relative to said body member causes said forceps jaws to open and close. - View Dependent Claims (17, 18, 19, 20)
