Beltless staple chain for cartridge and cartridgeless surgical staplers
View Patent ↗A surgical stapling device is configured for use in open and/or laparoscopic surgical procedures. The device includes a staple holder with a first support element and a second support element for supporting a beltless continuous staple chain. Each staple of the staple chain is configured to be frangibly separated from the staple chain to pierce and secure a target tissue when each staple is deployed. The device also includes a plurality of standoff members wherein each of the plurality of standoff members is configured to support one of each staple of the staple chain when the one of each staple is being deployed. The surgical stapling device may be a cartridge-based or a cartridge-less based staple device.
1. A surgical stapling device, comprising:
a staple holder, comprising:
a first support element and a second support element configured to support a staple chain,
wherein each staple of the staple chain is configured to be frangibly separated from the staple chain when each staple is deployed; and
wherein an end portion of one of each staple of the staple chain is frangibly coupled to a head portion of another one of each staple of the staple chain; and
a plurality of standoff members, wherein each of the plurality of standoff members is configured to support one of each staple of the staple chain when the one of each staple is being deployed.
2. The surgical stapling device of claim 1 , wherein the first support element provides lateral support to the staple chain.
3. The surgical stapling device of claim 1 , wherein the second support element provides vertical support to the staple chain.
4. The surgical stapling device of claim 1 , wherein each of the plurality of standoff members is respectively coupled to the first support element along various locations or positions along a length or surface of the first support element.
5. The surgical stapling device of claim 1 , wherein while one staple of the staple chain is deployed, each staple of a remainder of the staple chain is held in place by a respective standoff member.
6. The surgical stapling device of claim 1 , wherein each staple of the staple chain is frangibly coupled to at least one other staple of the staple chain.
7. The surgical stapling device of claim 1 , wherein one of each staple of the staple chain is frangibly separable from another one of each staple of the staple chain at a frangible connection region, location, or point when the one of each staple of the staple chain is being deployed.
8. The surgical stapling device of claim 7 , wherein the frangible connection region, location, or point is where an end portion of one of each staple of the staple chain meets, connects, couples, or joins to a head portion of another one of each staple of the staple chain.
9. The surgical stapling device of claim 1 , further comprising:
a wedge element, deployed within the staple holder, configured to directly act on each staple of the staple chain to deploy each staple.
