  • Patent number: 11998198
    Abstract: A surgical stapling instrument comprising an end effector is disclosed. The end effector comprises an anvil and a cartridge jaw comprising a channel, wherein the channel comprises a lockout recess defined therein. A staple cartridge is replaceably seated in the channel. A firing member is configured to distally advance a sled during a staple firing stroke. The firing member comprises a first portion configured to engage the anvil, a second portion configured to engage the cartridge jaw, and a lockout portion positioned between the first portion and the second portion. The lockout portion is configured to engage the lockout recess when the sled is not in a proximal position prior to the staple firing stroke. The surgical stapling instrument is unable to perform the staple firing stroke when the lockout portion engages the lockout recess.

  • Patent number: 11896225
    Abstract: A surgical severing and stapling instrument, suitable for laparoscopic and endoscopic clinical procedures, clamps tissue within an end effector of an elongate channel pivotally opposed by an anvil. An E-beam firing bar moves distally through the clamped end effector to sever tissue and to drive staples on each side of the cut. The E-beam firing bar affirmatively spaces the anvil from the elongate channel to assure properly formed closed staples, especially when an amount of tissue is clamped that is inadequate to space the end effector. In particular, an upper pin of the firing bar longitudinally moves through an anvil slot and a channel slot is captured between a lower cap and a middle pin of the firing bar to assure a minimum spacing. Forming the E-beam from a thickened distal portion and a thinned proximal strip enhances manufacturability and facilitates use in such articulating surgical instruments.

  • Publication number: 20230329704
    Abstract: A staple having a crown, a deformable leg extending from the crown, and a spring extending from the crown configured to compress tissue between the spring and the deformable member. Owing to the flexibility of the spring, the staple can accommodate a wide range of tissue thicknesses while still compressing the tissue captured therein. As a result, a single staple design can be used in a wide variety of surgical procedures thereby reducing the amount of staple designs that must be provided to the surgeon. In at least one embodiment, the staple includes a crushable member. This crushable member can include a plastically deformable first portion and an elastically deformable second portion. The present invention can also include, in various embodiments, a crown, a first deformable member extending from the crown, and means for compressing the tissue against the first deformable member.
