Resposable anastomotic ring applier device
First Claim
1. A surgical instrument for deploying an anastomotic ring device at an anastomosis site, the instrument comprising:
- (a) a distal portion, the distal portion comprising a ring deployment mechanism, wherein the ring deployment mechanism is configured to receive and deploy an anastomotic ring;
(b) a proximal portion in communication with the distal portion, the proximal portion comprising one or more actuation members operable to actuate at least a portion of the ring deployment mechanism; and
(c) a shaft comprising a distal portion and a proximal portion, wherein the distal portion of the shaft comprises a first plurality of tubes, wherein the proximal portion of the shaft comprises a second plurality of tubes, wherein each tube in the first plurality of tubes in the distal portion of the shaft comprises a flange, wherein each tube in the second plurality of tubes in the proximal portion of the shaft comprises a clip arm configured to selectively engage the flange of a corresponding tube of the first plurality of tubes, wherein the distal portion of the shaft is selectively removable from the proximal portion of the shaft;
wherein the distal portion of the instrument is selectively removable from the proximal portion of the instrument, wherein the distal portion of the instrument and the proximal portion of the instrument are in communication via the shaft.

Abstract
A surgical instrument that is operable to deploy an anastomotic ring device comprises a proximal portion and a distal portion. The distal portion comprises a ring deployment mechanism, which is configured to receive and deploy an anastomotic ring. The proximal portion comprises a mechanism that is operable to remotely actuate the ring deployment mechanism. The distal portion is removable from the proximal portion. The distal portion may be selectively engaged with the proximal portion by a series of annular flanges and clamp arms that are configured to engage the annular flanges. The ability to remove the distal portion of the instrument permits the replacement of the ring deployment mechanism without requiring the replacement of the instrument in its entirety.
