Coniploto Specification for the Invention entitled: SURGICAL STAPLER CART’RIIICE LOCKOUT
DEVICE
lho following statoment is a full description of tlls Invention, including the best method of performing it known to me/us:- .I I i I- 1Av SU CGAb 4TAP1LR CARTRPM E OCVT PEVIUf Field of the Tnventign This invention is generally related to a device for prevention of rofiring of surgical staplers. More spoei£ically, tlhis invention is related to a device which prevents the refiring and reloading of a Rpent staple cartridge in a surgical1 stapler, pagroipI of the invontiQn Surgical sLaplers have becoeo a very typical form of wound clesureo during tu’gery. These surgical staplers can perform various functions such as closing internal wounds, as well as suturing skin* Many of thoese surgical staplers have reloadable cartridges. These cartridges allow for the rapid reloading of the surgical stapler during the operation. That is, the stapler can be used, the spent cartridge removod, and the surgical stapler reloaded with another cartridge and ready for use.
One problem, however, is the refiring of staplers containing spent cartridges. In other words, during the course of surgery it may be possible for the rurgeon to use the surgical stapler and then inadvertently not reload the stapler with an unused cartridge. The stapler is then inserted into the wound for use, and then fired. Of course, because the cartridge is already spent, the stapler will not be able to fire another round of t staples. This results in a delay while reloading the surgical stapler.
-2- A aim of the present invention is to ameliorate the problems of the prior art by providing the surgical stapler with a lockout mechanism which is actuable on firing of the a stapler.
Accordingly, in a first aspect, the present invention provides a surgical stapler having firing means for firing ataples and in which a removable zartridge containing staples may be loaded and replaced by another remuovable cartridge, a lockout mechanism on said stapler actuable by said firing means upon the firing of said staples by said stapler such that said lockout mechanism blocks said firing mWeans and prevents the ref iring of said stapler when loaded with a spent cartridge.
In a second aspect, the present invention provides a ‘coo cartridge containing surgical staples and a path wherein a firing means from a surgical stapler can move in order to fire said stapler, a lockout mechanism comprising a firing barrier loaded by a first spring, said barrier preloaded on said cartridge before the insertion of said cirtridge into a surgical stapler, said first spri4ng actuable upon the firing of said stapler by said firing means located on said stapler, such that said barrier is caused by said first spring to move into said path to prevent the refiring of said stapler loaded with a spent cartridge.
in a third aspect, the present invention provides a staple cartridge insertable within a surgical stapler and containing staples and comprising an elongated body including one or more longitudinal slots for slidably receiving one or miore longitudinal pusher bars comprising a firing mechanism of said surgical stapler, and a plurality of drivers engageable by said pusher bars for ejecting the staples from the cartridge, said staple cartridge releasably fastened to a said surgical stapler, the surgical stapler further comprising a lockout mechanism connected to said longitudinal slots for preventing said pusher bars from passing more than one time through said longitudinal slots.
