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.
We claim: 1. A reconfigurable surgical apparatus, comprising: a surgical instrument assembly formed with a hollow manipulation shaft internally 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 capt
We claim: 1. A reconfigurable surgical apparatus, comprising: a surgical instrument assembly formed with a hollow manipulation shaft internally 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; an interchangeable surgical tool attachable to the coupler and including an anchor adapted to cooperate with and mate to the capture ledge, such that a rotational force applied to the prime mover is transmitted between the prime mover and the tool; wherein said anchor is formed with at least one generally hook shaped tine, formed with a frangible portion, that includes an engagment face adapted to cooperate with and non-releasable engage the capture ledge; and wherein said anchor is formed with the frangible portion designed to break in an orientation substantially orthogonal to a direction of translation of the prime mover. 2. The apparatus according to claim 1, wherein the capture ledge is further formed in the coupler to define at least one lateral recess adapted to cooperate with and receive the anchor thereby transferring rotational force from the prime mover to the tool. 3. The apparatus according to claim 1, wherein the frangible portion is substantially sealed from an exterior environment by the coupler and the manipulation shaft. 4. A reconfigurable surgical apparatus, comprising: a surgical instrument assembly formed with a hollow manipulation shaft internally 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 recess in the coupler; an interchangeable surgical tool adapted to cooperate with and connect to the coupler comprising a frangible portion and an anchor adapted to cooperate with and non-releasably mate to the capture ledge thereby transferring a rotational force applied to the prime mover from the prime mover to the tool, the frangible portion being adapted for receipt in the recess after the anchor has been removed from the tool; and wherein said anchor is formed with the frangible portion designed to break in an orientation substantially orthogonal to a direction of translation of the prime mover. 5. A reconfigurable surgical apparatus, comprising: a surgical instrument assembly formed with a hollow manipulation shaft internally 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; an interchangeable surgical tool adapted to cooperate with and connect to the coupler and formed with a capture ledge adapted to cooperate with and mate to the anchor thereby transferring a rotational force applied to the prime mover from the prime mover to the tool; wherein said anchor is formed with at least one generally hook shaped tine, formed with a frangible portion, that includes an engagement face adapted to cooperate with and non-releasable engage the capture ledge; and wherein said anchor is designed to break in an orientation substantially orthogonal to a direction of translation of the prime mover. 6. The apparatus according to claim 5, wherein the capture ledge is further formed in the tool to define at least one lateral recess adapted to cooperate with and non-releasably receive the anchor. 7. A reconfigurable surgical apparatus, comprising: a surgical instrument assembly formed with a hollow manipulation shaft internally 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; an interchangeable surgical tool formed at an end with a capture ledge that defines a lateral recess in the tool, the ledge being adapted to cooperate with and mate to the engagement face thereby transferring a rotational force applied to the prime mover from the prime mover to the tool; wherein said anchor is formed with a frangible portion, that includes an engagement face adapted to cooperate with and non-releasably engage the capture ledge; and wherein said anchor is designed of break in an orientation substantially orthogonal to a direction of translation of the prime mover. 8. A reconfigurable surgical apparatus, comprising: a surgical instrument assembly formed with a hollow manipulation shaft internally 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; an interchangeable surgical tool configured to connect to the coupler and formed with a reciprocating capture member adapted to cooperate with and non-releasably mate to the anchor thereby transferring a rotational force applied to the prime mover from the prime mover to the tool; wherein said anchor is formed with at least one generally hook shaped tine, formed with a frangible portion; and wherein said anchor is formed with the frangible portion designed to break in an orientation substantially orthogonal a direction of translation of the prime mover. 9. The apparatus according to claim 8, wherein the capture member is further formed in the tool to define at least one lateral recess adapted to cooperate with and receive the anchor. 10. 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 internally received with a means for transmitting the imparted range of motion; a means for distally coupling the passageway means that defines a means for anchoring; an interchangeable means for performing a surgical intervention that includes a means for capturing the anchoring means; wherein the interchangeable intervention means is, when mated to the anchoring means, remotely actuatable by operation of the motion imparting means and thereby transmits a rotational force applied to the motion imparting means between the motion imparting means and the interchangeable intervention means; wherein said anchoring means is formed with at least one generally hook shaped tine that includes an engagement face adapted to cooperate with and non-releasably engage the means for capturing; and wherein the means for anchoring is further formed with a means for defining a frangible portion of the anchoring means designed to break in an orientation substantially orthogonal to a direction of translation of the motion imparting means. 11. The means for performing an intracorporeal surgical procedure according to claim 10, wherein the capturing means is further formed in the intervention means to define at least one means for defining a lateral recess adapted to cooperate with and non-releasably receive the anchoring means. 12. The means for performing an intracorporeal surgical procedure according to claim 11, wherein the anchoring means is formed as a generally hook shaped tine having an end sized for non-releasable receipt into the recess. 13. The means for performing an intracorporeal surgical procedure according to claim 11, wherein the anchoring means is formed with a frangible portion defining means adapted to cooperate with and be removably received in the recess after the frangible portion defining means has been severed.
