Abstract
A reconfigurable surgical apparatus that includes a surgical instrument assembly that is formed with a hollow manipulation shaft. A linearly or rotationally movable prime mover is received within the shaft and is activated by an actuator located at a proximal end. A coupler is formed about a distal end of the shaft to have a capture ledge that is configured to releasably engage an interchangeable surgical tool that is formed with an anchor adapted to releasably mate to the capture ledge. The coupler may optionally incorporate a frangible portion that severs a portion of the coupler when the interchangeable surgical tool is removed from the apparatus to ensure single use operation of the tool.
Claims42
A reconfigurable surgical apparatus, comprising:
- a surgical instrument assembly formed with a hollow manipulation shaft receiving a prime mover activated by an actuator located at a proximal end of the shaft;
- a coupler formed about a distal end of the shaft and having a capture ledge;
- and
- an interchangeable surgical tool attachable to the coupler and including an anchor adapted to releasably mate to the capture ledge.
A reconfigurable surgical apparatus, comprising:
- a surgical instrument assembly formed with a hollow manipulation shaft receiving a prime mover activated by an actuator located at a proximal end of the shaft;
- a coupler formed about a distal end of the shaft having a capture ledge that defines a slot in the coupler;
- and
- an interchangeable surgical tool adapted to connect to the coupler comprising a frangible portion and an anchor adapted to releasably mate to the capture ledge, the frangible portion being adapted for receipt in the slot after the anchor has been removed from the tool.
A reconfigurable surgical apparatus, comprising:
- a surgical instrument assembly formed with a hollow manipulation shaft receiving a prime mover activated by an actuator located at a proximal end of the shaft;
- a coupler formed about a distal end of the shaft having a capture ledge that defines a lateral slot in the coupler;
- and
- an interchangeable surgical tool for attachment to the coupler and formed with an anchor having a shear notch, the anchor being adapted to releasably mate to the capture ledge and to be severed from the tool about the notch.
A reconfigurable surgical apparatus, comprising:
- a surgical instrument assembly formed with a hollow manipulation shaft receiving a prime mover activated by an actuator located at a proximal end of the shaft;
- a coupler formed about a distal end of the shaft and incorporating an anchor;
- and
- an interchangeable surgical tool adapted to connect to the coupler and formed with a capture ledge adapted to releasably mate to the anchor.
A reconfigurable surgical apparatus, comprising:
- a surgical instrument assembly formed with a hollow manipulation shaft receiving a prime mover activated by an actuator located at a proximal end of the shaft;
- a coupler formed about a distal end of the shaft to have a generally hook shaped anchor having an engagement face;
- and
- an interchangeable surgical tool formed at an end with a capture ledge that defines a lateral slot in the tool, the ledge being adapted to releasably mate to the engagement face.
A reconfigurable surgical apparatus, comprising:
- a surgical instrument assembly formed with a hollow manipulation shaft receiving a prime mover activated by an actuator located at a proximal end of the shaft;
- a coupler formed about a distal end of the shaft and formed with an anchor;
- and
- an interchangeable surgical tool configured to connect to the coupler and formed with a reciprocating capture member adapted to releasably mate to the anchor.
A reconfigurable surgical tool, comprising:
- a surgical instrument assembly formed with a hollow manipulation shaft receiving a prime mover activated by an actuator located at a proximal end of the shaft;
- a coupler formed about a distal end of the shaft and including a receiver having an engagement ledge and shelf;
- and
- an interchangeable surgical tool attachable to the coupler that includes an engager adapted to releasably mate to the receiver.
A reconfigurable surgical tool, comprising:
- a surgical instrument assembly formed with a hollow manipulation shaft receiving a prime mover activated by an actuator located at a proximal end of the shaft;
- a coupler formed about a distal end of the shaft and formed with an engager;
- and
- an interchangeable surgical tool formed with a receiver formed with an engagement ledge and shelf and adapted to releasably mate to the engager.
A means for performing an intracorporeal surgical procedure, comprising:
- a means for imparting a range of motion;
- a means for defining an intracorporeal passageway connected at a proximal end to the motion imparting means, the passageway being received with a means for transmitting the imparted range of motion;
- a means for distally coupling the passageway means that defines a means for interchangeably capturing;
- an interchangeable means for performing a surgical intervention that includes a means for releasably mating the intervention means to the capturing means;
- and
- wherein the interchangeable intervention means is, when mated to the capturing means, remotely actuatable by operation of the motion imparting means.
