摘要: A method of applying a buttress to a surgical stapler end effector comprises positioning a buttress assembly between an anvil and a staple cartridge of the end effector. The buttress assembly comprises a buttress body and an adhesive material. The adhesive material faces either an underside of the anvil or a deck of the staple cartridge. The anvil is in an open position relative to the staple cartridge during the act of positioning the buttress assembly between the anvil and the staple cartridge. The method further comprises moving the anvil toward the staple cartridge then moving the anvil back to the open position. The buttress assembly is adhered to the underside of the anvil or the deck of the staple cartridge via the adhesive material with the anvil moved back to the open position. The adhesive material comprises a bioabsorbable polymer.

摘要: In various embodiments, a shaftless end effector is disclosed. The end effector can comprise an anvil assembly including a staple forming surface. The end effector can also comprise a staple cartridge channel configured to receive a staple cartridge therein. The end effector can include a closure system configured to close the anvil. In various instances, the closure system can also form the staples contained within the staple cartridge. The end effector can also include a cutting member configured to cut tissue positioned intermediate the anvil and the staple cartridge. In various instances, the cutting member can be actuated by the closure system. In other instances, the end effector can include an independent system for actuating the cutting member. In various instances, the end effector can be delivered to a surgical site through a trocar and then operated by one or more actuators that are assembled to the end effector.

摘要: A surgical visualization system is disclosed. The surgical visualization system is configured to identify one or more structure(s) and/or determine one or more distances with respect to obscuring tissue and/or the identified structure(s). The surgical visualization system can facilitate avoidance of the identified structure(s) by a surgical device. The surgical visualization system can comprise a first emitter configured to emit a plurality of tissue-penetrating light waves and a second emitter configured to emit structured light onto the surface of tissue. The surgical visualization system can also include an image sensor configured to detect reflected visible light, tissue-penetrating light, and/or structured light. The surgical visualization system can convey information to one or more clinicians regarding the position of one or more hidden identified structures and/or provide one or more proximity indicators.

摘要: An anvil-attachable layer for use with a surgical stapler, or fastening instrument, wherein a proximal end portion of the layer is attached to a staple cartridge assembly, for example. The layer may be attached to the staple cartridge assembly by an adhesive, weld, or a staple-cartridge-based clamp, wherein the attachment is weak enough to allow the layer to pull away from the staple cartridge assembly with stapled tissue. Alternatively, the layer can include two or more lateral slits that define a connector region that can be cut by a knife of a surgical stapler to release the layer.

摘要: Various methods and devices are provided for allowing multiple surgical instruments to be inserted into sealing elements of a single surgical access device. The sealing elements can be movable along predefined pathways within the device to allow surgical instruments inserted through the sealing elements to be moved laterally, rotationally, angularly, and vertically relative to a central longitudinal axis of the device for ease of manipulation within a patient's body while maintaining insufflation.

摘要: An apparatus comprises a body, a shaft assembly, an end effector, a cartridge, and a staple driver actuator. The end effector is operable to manipulate tissue. The end effector comprises a lower jaw, a pivotable anvil, and a translating cutter. The translating cutter is operable to translate relative to the lower jaw and the anvil when the anvil is pivoted toward the lower jaw to manipulate tissue. The cartridge is insertable into the lower jaw and includes a plurality of staples. The staple driver actuator is disposed within the cartridge. The staple driver actuator comprises a secondary cutting element. The translating cutter of the end effector is operable to drive the staple driver actuator distally to staple and cut tissue substantially simultaneously.

摘要: A buttress is applied to an end effector of a surgical stapler. The buttress is loaded on a platform of a buttress applier cartridge. The end effector is closed upon the platform. An adhesive layer of the buttress secures the buttress to the end effector. The buttress is thus adhered to the end effector when the end effector is opened. The end effector is then actuated on tissue of a patient, thereby stapling the buttress to the tissue.
