Fluid delivery device for use with anastomosing resecting and stapling instruments
A fibrin injection mechanism for use in combination with an anastomosing and stapling attachment for an electromechanical device driver comprises a cylindrical dispensing chamber adjacent the cylindrical blade of the attachment and containing a sac filled with fibrin, a plurality of channels extending within the blade communicating between the dispensing chamber and the cutting edge of the blade, such that when the turning drive shaft is activated, the staple driver of the attachment moves forward to push a plurality of staples through corresponding staple ports and against the anvil of the attachment to pass through and staple together the target tissue, while the blade driver of the attachment moves forward to cut the unwanted residual tissue (post stapling), while a plunger (delivery) driver moves forward through the dispensing chamber to compress the sac to its break point, releasing the fluid medication into the dispensing chamber, and eventually pushing the medication though the channels to deliver the fibrin to the cutting edge of the blade and thus to the site of the newly stapled target tissue to accelerate the healing process.

Surgical stapling instrument with an anti-back up mechanism
A surgical instrument including a firing drive configured to advance a cutting member and / or staple driver within an end effector, and a brake configured to prevent, or at least partially inhibit, the relative movement of the cutting member and / or staple driver. The surgical instrument can further include a firing member operably engaged with the cutting member, for example, a band connected to the firing member, and a reel, where the band can be configured to be wound around the reel. In various embodiments, the brake can be selectively engageable with the reel and / or band to prevent, or limit, the movement of the band. The brake can include a brake surface where relative movement between the band and the brake surface can generate a friction force therebetween which can hold the firing member in position until a sufficient force is applied to the firing member to overcome the friction force.

Surgical instrument for progressively stapling and incising tissue
An instrument including a clamping jaw with an anvil defining an elongated slot and staple forming cups on opposing sides of the elongated slot. A housing rotatably mounts on the anvil and a pusher rotatably mounts within the housing. A handle actuates the clamping jaw from the open to the intermediate position by rotating the housing towards the clamping jaw. To move from the intermediate position to the closed position, the pusher rotates towards the anvil. A staple cartridge, disposed in the housing, includes a staple track for retaining two rows of staples on opposing sides of the elongated slot. Two staple drivers align with the distal most staples. The drivers slidably mount in the staple cartridge and couple to the pusher such that each staple driver forces a staple into the forming cups and, in turn, staples the body tissue as the pusher rotates from the intermediate to closed position. A knife rotatably mounts on the staple cartridge and couples to the pusher such that the knife passes into the elongated slot and, in turn, cuts the body tissue as the pusher rotates from the intermediate to closed position.

ActiveUS7819299B2Quickly and conveniently selectSuture equipmentsStapling toolsSurgical operationSurgical site
A surgical instrument including a trigger which can be configured to close a jaw member upon a first actuation of the trigger and advance a staple driver and / or cutting member upon a subsequent, or second, actuation of the trigger. Such a surgical instrument can allow a surgeon to position the surgical instrument in a surgical site and close the jaw member with an initial actuation of the trigger without deploying any staples into, or incising, the tissue. As a result, the surgeon can manipulate the position of the surgical instrument and then actuate the trigger a second time to deploy staples into, and / or incise, the tissue. In at least one such embodiment, the first actuation of the trigger which closes the jaw member can also unlock a firing drive configured to advance the staple driver and cutting member during the second actuation of the trigger.

A surgical instrument including a drive mechanism configured to advance a staple driver and / or cutting member at a first rate and retract the staple driver and / or cutting member at a different rate. In at least one embodiment, the rate at which the driver and cutting member is advanced and / or retracted is the distance that the driver and / or cutting member is translated per actuation of a trigger, for example. In various embodiments, the cutting member can be retracted at a faster rate as compared to the rate in which it is advanced. In such embodiments, the surgical instrument can, owing to the slower advancing rate, provide a greater torque or advancing force to the cutting member while, owing to the faster retracting rate, reduce the time required for the surgeon to retract the cutting member.

ActiveUS20070073340A1Large thicknessPrevents excessive flexureSuture equipmentsStapling toolsSurgical staplePERITONEOSCOPE
A surgical instrument for being endoscopically or laparoscopically inserted into a surgical site for simultaneous stapling and severing of tissue includes force adjusted spacing between an upper jaw (anvil) and a lower jaw (staple cartridge engaged to an elongate staple channel) so that the height of staple formation corresponds to the thickness of the tissue, yet does not exceed the height range that may be accommodated by the length of the staples. In particular, collapsible staple drivers may be supported within the cartridge for driving a staple or staples supported thereon into forming contact with an underside of an anvil attached to the instrument. As the staples contact the anvil, the drivers can compress or collapse to control the overall formed height of the staple or staples based upon the amount of compression forces experienced by the drivers during the stapling process.

Stapler apparatus to staple stacks of paper with different thicknesses
A staple apparatus is installed in a stapler so the stapler can staple stacks of paper with different thicknesses without having to change staples or components in the stapler. The apparatus cuts legs of a staple to a proper length after the staple has been driven completely into a stack of paper and bends the protruding ends to bind the stack of paper together. The apparatus performs these operations with a cutter, a bending template, and a cutting anvil in conjunction with a sliding bracket and a cutter actuator. Operation of the cutter is delayed by a staple driver actuator until the staple has completely penetrated the stack of paper.
