摘要:
A surgical staple including at least one deformable member which can be bent upon contacting an anvil of a surgical stapler. In various embodiments, at least a portion of the deformable member can include a non-circular cross-section which can dictate the direction and manner in which the deformable member is bent. In at least one various embodiment, the non-circular cross-section can include a flat portion which can cause the deformable member to bend in the direction of the flat portion. In various embodiments, the non-circular portion of the cross-section can be configured to abut soft tissue of a patient and apply a compressive force or pressure thereto. In various embodiments, a crown formed on the surgical staple can dissolve as the soft tissue heals and can, depending on the cross-sectional geometry of the deformable member, reduce the force or pressure applied to the soft tissue by the deformable member.

A surgical staple including at least two deformable members which can be bent upon contacting an anvil of a surgical stapler. In various embodiments, at least a portion of the deformable members can include a non-circular cross-section which can dictate the direction and manner in which the deformable members are bent. In at least one embodiment, the non-circular cross-section can include a flat portion which can cause the deformable members to bend in the direction of the flat portion. In various embodiments, the at least two deformable members can be connected by a dissolvable or bioabsorbable crown. In at least one various embodiment, the crown can dissolve and can, depending on the cross-sectional geometry of the deformable members, reduce the force or pressure applied to soft tissue captured within the staple by the bent deformable member.

A staple cartridge for use with a stapling device that has an actuator that is selectively actuatable in an axial direction and an anvil portion that is selectively movable between open and closed positions is disclosed. Various embodiments of the present invention include a cartridge body that movably supports first and second staple drivers. The staple drivers each support a staple thereon and serve to drive the staples into forming contact with the anvil upon actuation by the actuator. The various embodiments of the present invention enable the final formed heights of the staples to be varied so as to apply various clamping forces and pressures to soft tissue captured within the staples. In at least one embodiment, the staples can include crowns formed thereon which can be utilized to adjust or control the clamping force and/or pressure applied by the staples.
摘要:
A surgical staple including a crown comprised of a dissolvable, bioabsorbable, or biofragmentable material, a first deformable member, and a second member. In at least one embodiment, the crown connects the first member and the second member, however, after the crown has been dissolved, the first member is unconnected to the second member and, as a result, the first and second members can move relative to each other. Accordingly, the staple can be rigid during the early stages of healing and can be flexible during the latter stages of healing, for example. In various embodiments, the first and second members of the staple are also comprised of a dissolvable, bioabsorbable, or biofragmentable material. In these embodiments, the first and second members can be constructed so that the crown and first and second members dissolve at different rates and/or dissolve away at different times.

A surgical staple including features which can reduce bleeding from soft tissue. In various embodiments, the surgical staple can include at least one deformable member which can puncture a hole in soft tissue as it is inserted therethrough. The deformable member can include a material thereon, or can be comprised of a material, which can expand and substantially fill the puncture hole in the soft tissue. In various embodiments, at least a portion of the deformable member can be coated with a hydrophilic material which can expand when exposed to water, or other bodily fluids, and apply a compression force to the perimeter of the puncture hole. Such a compression force can reduce bleeding from the puncture hole and thereby reduce any potential complications resulting therefrom.
