摘要:
A surgical stapling system comprising a first staple, a second staple, and a bridge connecting the first staple and the second staple. In at least one embodiment, the first staple and the second staple are part of a strip of staples. For example, the first and second staples can be included in a strip of staples that includes several staples that are attached end-to-end and/or attached side-by side. In use, the strip, or strips, of staples are inserted into a stapler which can be used to insert the staples into soft tissue, for example, and deform at least a portion of the staples to hold the tissue, or several layers of tissue, together.

A surgical stapling system including a driver and a staple where the driver is connected to the staple. In previous surgical stapling systems, the driver and the staple were not connected. A surgical stapling system in accordance with the present invention may have fewer components, less assembly and manufacturing time, and may accommodate larger staples which are at least partially embedded in the driver. In various embodiments, a surgical stapling system comprises a staple, the staple including a deformable member, and a stapler, the stapler including an anvil, a staple cartridge for removably storing the staple, and a cam movable between a first position and a second position. In these embodiments, the surgical stapling system further comprises a driver attached to the staple, the driver being operatively engaged with the cam to move the staple toward the anvil when the cam is moved between the first position and the second position.

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 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.
摘要:
A staple having a crown and first and second deformable members extending from the crown. In at least one embodiment, the staple further includes a base connecting the first and second deformable members where the base is not entirely co-planar with the first and second deformable members. In these embodiments, the crown can be overmolded onto, or attached to, the base and provide a larger and/or more stable tissue-contacting surface for supporting the tissue captured by the staple. As a result, the possibility of the staple being pulled through the tissue and/or the tissue tearing within or around the staple is reduced.
摘要:
A surgical staple including a crown and a deformable member extending from the crown, the deformable member having a notch configured to cause the deformable member to bend at the notch when the staple is deformed from a first shape into a second shape. The crown of the surgical staple, in various embodiments, further includes a forming surface, or anvil, which is configured to deform the deformable member and/or guide a distal end of the deformable member when the distal end contacts the crown.
摘要:
A method of manufacturing staples including the steps of placing a deformable member into a mold block and overmolding a crown onto the deformable member. In various embodiments, several deformable members may be produced from an elongate wire where the deformable members can be connected by portions of the wire. In at least one such embodiment, the elongate member can then be cut to separate the deformable members to form a plurality of surgical staples or strips of surgical staples.
摘要:
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 first apparatus for cleaning a distal end of a medical scope includes an annular sheath surroundingly attachable to the scope wherein the distal scope end is in fluid communication with the distal end of a lumen of the attached sheath with the proximal lumen end fluidly connectable to an irrigation fluid source and/or vacuum source. A second apparatus includes a motor-driven rotatable cannula having a closed distal end. A third apparatus includes an annular sheath and a lens which closes off the sheath, wherein the scope is insertable into the sheath, and wherein the lens is exposed to a distal lumen end of a lumen of the attached sheath. A fourth apparatus includes an annular sheath and a transparent shield rotatable attachable to the sheath to seal the distal sheath end. A fifth apparatus includes a sleeve attachable to and slidable along a scope.
