摘要:
In various embodiments, a surgical test device for a surgical tool, such as a severing and/or sealing tool (e.g., a surgical stapler), is provided. In at least one embodiment, the surgical tool can be configured to supply at least one actuation motion to an end effector. The actuation motion(s) may cause a cutting member to move within and/or sealing members (e.g., staples) to eject from the end effector. Further, in at least one embodiment, the surgical test device can be releasably engaged to a portion of the surgical tool, such as the end effector. Additionally, the surgical test device can be configured to permit the surgical tool to supply the actuation motion(s) while preventing the tool from performing its intended surgical function. Accordingly, the surgical tool may be test fired without wasting a sealing member cartridge, while preventing inappropriate use of the tool when the test device is attached thereto.

A surgical fastener apparatus including a handle, an elongated shaft having a proximal end attached to the handle and a distal end extending therefrom. An end effector comprising a pair of jaws pivoted at a proximal end thereof and movable between an open and closed position, and a cartridge containing a plurality of surgical fasteners, the cartridge attached to the end effector. An electrically powered actuator for deploying the surgical fasteners. An electrically activated reverse mechanism for moving the elongated member from a distal most position within the end effector to a proximal position, the electrically activated reverse mechanism moves the elongated member proximally after the elongated member has moved to the distal most position by moving the trigger to the open position, and wherein after activation of the reverse mechanism proximal movement of the elongated member can be stopped by returning the trigger to its closed position.

摘要:
A surgical instrument includes a handle portion, a shaft housing a firing bar, an end effector comprising an anvil, a lower jaw, and a stapling and severing assembly responsive to a longitudinal closing motion produced by the handle portion and the shaft. The lower jaw is configured to receive a removable cartridge. The cartridge includes a housing, a plurality of staples disposed in the housing, and a deck disposed over the plurality of staples. The deck defines apertures, with each aperture being substantially disposed over each staple. The cartridge further receives a buttress material stored in one or both of the anvil or cartridge. The material is releasable onto severed tissue via a firing bar severing the buttress material in response to the longitudinal closing motion.

An instrument is configured to receive a staple cartridge to staple tissue and expel a fluid from within a container in the staple cartridge. The staple cartridge has an upper deck including staple apertures and orifices formed therein. The orifices are in fluid communication with the containers. The staple cartridge includes staple drivers having a driver body to translate a staple and a container protrusion to expel the fluid out the orifices. The fluid may be expelled while driving the staples out through the staple apertures. The container may be vertically compressible container or, in one alternative, may be a container having a channel and a sealant that is configured to be pierced as the fluid is expelled. Some configurations for the fluid include a hemostatic agent, thrombin, a gel, or a medicament. The containers may also be formed as reservoirs defined within the upper deck and/or cartridge body.
摘要:
A creeper cum work seat has two end platforms (1, 5) in sliding attachment to slide rods (4, 35, 36) in slideways (3, 6) with which the two end platforms can be slid apart to opposite ends of a central platform (7) to form a full-length creeper in creeper mode (11). The central platform becomes a work seat and the two end portions become a shelf platform under the work seat when the two end platforms are slid edge-to-edge in a seat mode(10). Seat-support members (12, 13) are attached pivotally to the central platform and to the two end platforms to support the central platform as a seat in a seat mode and to position the central portion between the two end platforms in a creeper mode.

A vehicle seat latch (24) includes a latch member (40) and a blocking member (70) that each have associated first and second blocking surfaces (80, 82 and 88, 90) for holding the latch member in a latched position with the blocking member in a blocking position. The first blocking surfaces (80 and 88) of the latch member and blocking member have a pressure angle between 4.6 and 6.6 degrees while the second blocking surfaces (82 and 90) have a zero degree pressure angle and are slightly spaced from each other. A deformable blocking portion (84) of the blocking member (70) defines its first blocking surface (88) and is deformed by excessive loading so that the zero degree pressure angle second blocking surfaces (82 and 90) then contact each other to hold the latch member in its latched position.

摘要:
A recumbent bicycle with (i) a cantilevered bicycle seat and (ii) a coaxial pivot and mid-drive sprocket around which the bicycle can be folded so as to form a more compact configuration. The folding of the bicycle is facilitated by the splaying of support arms for the coaxial pivot and mid-drive sprocket, which splaying allows the rear portion of the bicycle to be folded into a position lying between the splayed support arms.
