Endoscopic instrument with detachable end effector
First Claim
1. A surgical instrument for use in endoscopy comprising:
- a tubular member comprising a proximal portion and a distal portion, the two portions having coupling means for attaching and detaching the distal portion to and from the proximal portion;
an end effector comprising a first piece and a second piece, each piece being pivotally attached directly to a distal end of the distal portion of the tubular member;
linkage extending through the tubular member, the linkage comprising a first elongated member and a second elongated member, each elongated member comprising a proximal section and a distal section, each of the distal sections being operably coupled at their distal end to one of the end effector pieces, each of the elongated member sections having mating means for attaching and detaching the respective distal section to and from its respective proximal section, the tubular member coupling means and elongated member mating means thereby allowing for detachment and replacement of an assembly comprising the end effector from and to the remainder of the surgical instrument; and
a handle attached to the proximal end of the proximal portion of the tubular member, the handle comprising;
a first control means for causing translational movement of the first elongated member relative to the second elongated member, thereby causing the end effector piece coupled to the first elongated member to pivot relative to the other end effector piece; and
a second control means independent of the first control means, the second control means for causing relative translational movement between the tubular member and both the first and second elongated members without significant relative translational movement between the first and second elongated members, thereby causing the first and second end effector pieces to pivot simultaneously in the same direction.

Abstract
A surgical instrument having a handle, barrel and detachable end effector is provided. The barrel is generally tubular, with one end being connected to the handle. The end effector is releasably attached to the other end of the barrel, with jaws which may be pivoted, rotated and operated independently through multiple linkage members connected to a motive power source housed in or attached to the handle. The instrument is operated and controlled by a microprocessor and multidimensional controller or electrical contacts included in the handle. In the preferred embodiment, closing of jaws is manual with locking means; also, the end effector is scissor-like, but other end effectors such as graspers, clamps, dissectors or needle drivers, with appropriate operating and linkage members, may be attached to the handle.
