Abstract
An electromechanical driver for use in gastrointestinal tract surgery, including a flexible sheath and a handle, is provided. Also dislosed are a series of surgical attachments which may be utilized in conjunction with the electromechanical driver. The handle of the driver includes at least one motor which is selectively engageable by the actuation of a trigger. The motor is coupled to a flexible drive shaft which extends through the flexible sheath. At a distal end of the flexible sheath, and correspondingly at the end of the drive shaft, the various surgical attachments may be coupled. The turning of the drive shaft provides the necessary power to actuate the surgical instrument.
Claims42
An electromechanical driver assembly for remotely driving surgical attachments having turning members therein, comprising:
- a flexible shaft including at least two flexible and axially rotating members disposed within the shaft,
- said rotating members having distal and proximal ends,
- each rotating member being capable of transmitting a torque applied to the proximal end thereof, therealong to said distal end thereof,
- said distal ends including means for coupling to said corresponding turning members of said surgical attachments;
- at least one steering wire disposed along the shaft and configured to steer the flexible shaft;
- and
- a handle portion including
- at least two selectively engageable motors disposed therein and coupled with corresponding ones of said rotating members whereby selective engagement of either of the at least two motors causes the corresponding rotating shaft to rotate, thus transmitting a torque to a corresponding turning member of a surgical attachment.
A combined electromagnetic driver and linear clamping and stapling attachment assembly, comprising
- an electromagnetic driver including
- a flexible shaft including at least two flexible and axially rotating members,
- said rotating members having distal and proximal ends,
- each rotating member being capable of transmitting a torque applied to the proximal end thereof, therealong to said distal end thereof,
- said distal ends including means for coupling to said corresponding linear clamping and stapling attachments;
- at least one steering wire disposed along the shaft and configured to steer the flexible shaft;
- and
- a handle portion, including
- at least two selectively engageable motors disposed therein coupled to corresponding ones of said rotating members of said flexible shaft, whereby selective engagement of either of the at least two motors causes the corresponding rotating shaft to rotate;
- and
- a linear clamping and stapling attachment including
- an interfacing portion having at least two turning members, each of said turning members being coupleable to one of said at least two flexible and axially rotating members,
- a pair of opposing jaws which are selectively separable and closeable in accordance with the rotation of one of the at least two turning members,
- a plurality of staples and a staple driver mechanism, said staple driver mechanism being selectively coupled in staple driving relation to a second one of the at least two turning members.
A combined electromagnetic driver and linear clamping and stapling attachment assembly, comprising
- an electromagnetic driver including
- a flexible shaft including at least two flexible and axially rotating members,
- said rotating members having distal and proximal ends,
- each rotating member being capable of transmitting a torque applied to the proximal end thereof, therealong to said distal end thereof,
- said distal ends including means for coupling to said corresponding linear clamping and stapling attachment;
- at least one steering wire disposed along the shaft and configured to steer the flexible shaft;
- and
- a handle portion, including
- corresponding at least two selectively engageable motors coupled to corresponding ones of said at least two flexible and axially rotating members of said flexible shaft, whereby selective engagement of either of the at least two motors causes the corresponding one of the flexible and axially rotating shaft to rotate;
- and
- an anastomosing and stapling attachment including
- an interfacing portion having at least two turning members, each of said turning members being coupleable to one of said at least two flexible and axially rotating members,
- an anvil portion which is selectively advanceable and retractable in accordance with the rotation of one of the at least two turning members,
- a blade and staple housing portion, selectively coupleable to said anvil portion, which housing portion further includes a blade and staple driver assembly which is coupled to a second one of the at least two turning members such that selective actuation of said second turning member causes said blade and said staple driver to advance out of the housing and toward the anvil portion.
