Surgical instrument
First Claim
1. A surgical instrument comprising:
- an instrument shaft having proximal and distal ends;
a tool disposed from the distal end of the instrument shaft;
a control handle coupled from the proximal end of the instrument shaft;
a distal motion member for coupling the distal end of said instrument shaft to said tool;
a proximal motion member for coupling the proximal end of said instrument shaft to said handle;
actuation means extending between said distal and proximal motion members for coupling motion of said proximal motion member to said distal motion member for controlling the positioning of said tool;
said handle having a distal receiver portion;
a shaft connector on said proximal motion member selectively engageable with and releaseable from said receiver portion;
and an actuation cable extending from said shaft connector to said tool for controlling the actuation of the tool.

Abstract
A medical instrument having a proximal control handle and a distal tool that are intercoupled by an elongated instrument shaft that is meant to pass internally of an anatomic body, proximal and distal movable members that respectively intercouple the proximal control handle and the distal tool with the instrument shaft, cable control means disposed between the movable members, an actuation member at the handle for controlling the distal tool through the movable members, and a coupler for selectively engaging or disengaging the shaft portion of the instrument from the handle portion. The handle has a distal receiver portion, and a shaft connector on said proximal motion member is selectively engageable with and releaseable from the receiver portion.

- 18. In a medical instrument having a proximal control handle and a distal tool that are intercoupled by an elongated instrument shaft that is meant to pass internally of an anatomic body, proximal and distal movable members that respectively intercouple said proximal control handle and said distal tool with said instrument shaft, cable control means disposed between said movable members, an actuation member at said handle for controlling said distal tool through said movable members, a tool coupler for selectively engaging or disengaging said distal tool and a control member mounted at said handle for controlling said tool coupler.
- 21. A method of controlling a medical instrument that has a proximal end including a control handle and a distal end including a distal tool, said control handle and distal tool being intercoupled by an elongated instrument shaft and said tool actuated from a tool control cable that is operated from an actuation lever at the handle, said method including providing proximal and distal movable members that respectively intercouple said proximal control handle and said distal tool with said instrument shaft, said proximal and distal movable members being intercoupled so that a motion at said proximal movable member controls said distal movable member, and supporting the proximal movable member for removable interlock with a receiver portion at the handle.
- 24. An instrument having a proximal control handle and a distal tool that are intercoupled by an elongated instrument shaft, proximal and distal movable members that respectively intercouple said proximal control handle and said distal tool with said instrument shaft, means disposed between said movable members so that a motion at said proximal movable member controls said distal movable member and, in turn, the distal tool, means supported at the handle for controlling the distal tool including a tool control cable that extends between the proximal movable member and the distal tool and an actuation lever mounted at the handle, said handle having a distal receiver portion, and a shaft connector on said proximal movable member selectively engageable with and releaseable from said receiver portion.
