An electrosurgical device comprises an end effector, a cutting member, and en electromechanical driver. The end effector comprises a pair of jaws that clamp tissue. The jaws include electrodes that deliver RF energy to clamped tissue. The cutting member cuts tissue clamped between the jaws. The electromechanical driver drives the cutting member. A control module commands the electromechanical driver, and regulates the delivery of RF energy to the electrodes, based on a combination of user input and feedback signals from the electrodes and from the electromechanical driver. The device may provide tactile feedback to the user through the user input feature, based on a load encountered by the cutting member. The device may alert the user when the exterior of end effector makes incidental contact with tissue, to avoid inadvertently burning the tissue. The device may include a removable battery pack to power the electromechanical driver and the electrodes.

A surgical instrument includes a handle assembly having a lower portion with a hingedly attached end piece. When open, the end piece allows for receipt of a data card in a lower portion aperture. When closed, the end piece covers the aperture. In another version, the aperture is configured to receive a data card and battery pack assembly. Information is readable from and to the data card to measure a number of minutes the instrument was used during a procedure. Such information is communicated via wired or wireless communication to another device to determine a payment for the number of minutes used. Minutes are buyable from the device and writable onto the data card prior to insertion of the card into the instrument. In another version, a testing sequence is used in saline or via a tissue proxy to test the functionality of an instrument prior to a procedure.
摘要:
An end-effector assembly configured to be attached to a surgical instrument. The end-effector assembly comprises a first jaw and a second jaw comprising a staple cavity. At least one of the first jaw and the second jaw is movable relative to the other jaw. The end-effector assembly comprises a staple removably positioned within the staple cavity and an electrically-conductive driver configured to move the staple between a first stored position in which the staple is at least partially positioned within the staple cavity and a second position in which the staple is at least partially deployed from the staple cavity into tissue positioned intermediate the first jaw and the second jaw. The staple comprises an electrode.
摘要:
A disposable loading unit for operable attachment to a surgical stapling apparatus. The disposable loading unit may have a carrier that supports a staple cartridge and an anvil assembly that is movable coupled to the carrier. The various embodiments may further have an axial drive assembly that is configured to impart a closing motion to the anvil assembly and also supports a cutting blade thereon. The axial drive assembly is configured to receive firing motions and retraction motions from the surgical stapling apparatus. Various embodiments have an anvil release assembly that enables the anvil assembly to be released from a clamping orientation in the event that the cutting blade becomes jammed during operation.

A multiple use adhesive dispenser facilitates precise, extended dispensing for a surgical procedure by sequentially positioning an ampoule containing a flowable material, such as a polymerizable monomer compound such as a cyanoacrylate adhesive. In one version particularly suited to an open surgical procedure, the ampoules are affixed to a tape substrate that is unreeled from an internal storage reel and transported proximate to an ampoule gripping mechanism with an underlying tape substrate peeled away and internally stored as each ampoule is positioned for dispensing. Actuating an ampoule advancement handle positions the next ampoule and squeezing a movable handle toward a fixed handle effects dispensing. Another version has an elongate shaft that internally augers each ampoule in succession into a pair of spaced jaws that are pinched together by actuating rods to dispense adhesive.
摘要:
In various embodiments, a surgical stapling instrument can include a handle, a shaft extending from the handle, wherein the shaft defines an axis, and a disposable loading unit which is assembled to the shaft in a direction which is transverse to the shaft axis. Such a connection between the disposable loading unit and the shaft can prevent, or at least inhibit, the disposable loading unit from being unintentionally displaced proximally and/or distally relative to the shaft of the surgical instrument. The surgical stapling instrument and/or disposable loading unit can further include a threaded collar and/or detent assembly configured to hold the disposable loading unit in place. In various embodiments, a disposable loading unit can include a lockout feature which can prevent, or at least inhibit, an expended disposable loading unit from being reassembled to the elongated body of the surgical instrument.

An apparatus for aseptic insertion includes a container, a first cover, and a second cover. The container includes a first compartment, a second compartment, and a detachable wall disposed between the first compartment and the second compartment. The first cover is sized and configured to attach to the first compartment and the second cover is sized and configured to attach to the container. The detachable wall may defined by a top portion, a portion of a first distal wall of the first compartment, and a portion of a second proximal wall of the second compartment. The detachable wall may be removably attached to the first cover by the top portion of the detachable wall.
摘要:
An apparatus for regulating the functioning of a patient's organ or duct includes an elongated member having a first end and a second end. A fastener is disposed on the first end of the elongated member. The fastener is configured to engage the second end of the elongated member so that the elongated member forms a loop around the organ or duct. A tension element is disposed for movement within the elongated member. A drive element is associated with and engages the tension element for causing the tension element to control the tension applied by the elongated member against a patient's body organ or duct. A tension release mechanism is associated with the tension element.
摘要:
An apparatus comprises a base and at least one indicator in communication with the base. The base comprises a housing and at least one slot. The at least one slot is shaped to receive a reusable component from a surgical instrument. The at least one indicator is in communication with the at least one slot. The base is configured to detect at least one characteristic related to the reusable component when the reusable component is placed into the at least one slot. Wherein the at least one indicator is configured to provide a signal to the user regarding the at least one characteristic.
