Surgical instrument having a power control circuit
In various embodiments, a surgical instrument comprising an end effector and a handle comprising an opening and an access panel covering the opening is disclosed. The surgical instrument further comprises a motor, a power source, a firing member movable through a staple firing stroke and a retraction stroke, an end-of-stroke switch configured to be actuated to automatically retract the firing member through the retraction stroke, and a bailout switch configured to prevent power from flowing from the power source to the motor when the bailout switch is in an open state and permit power to flow from the power source to the motor when the bailout switch is in a closed state. A user of the surgical instrument is provided access to a retraction lever to manually retract the firing member through the retraction stroke when the access panel is in the open position.

HEMOSTATIC CLIP AND AUXILIARY SYSTEM
A hemostatic clip and an auxiliary system are disclosed. The hemostatic clip includes a first clip arm (110), a second clip arm (120), a tightening tube (140), a middle clip arm (150), an intermediate assembly (160), a traction assembly (170), a control handle (180) and at least two separators (190). The traction assembly (170) is connected to both the control handle (180) and the intermediate assembly (160), and the intermediate assembly (160) is connected to the tightening tube (140). Both the first clip arm (110) and the second clip arm (120) are proximally connected to the traction assembly (170). The middle clip arm (150) extends through the tightening tube (140) and is fixed proximally to the intermediate assembly (160). The first clip arm (110) and the second clip arm (120) are disposed on opposite sides of the middle clip arm (150). The first clip arm (110) makes up a first clip together with the middle clip arm (150), and the second clip arm (120) makes up a second clip together with the middle clip arm (150). The control handle (180) is configured to open or close the first clip and/or the second clip corresponding to the first clip arm (110) and/or second clip arm (120). The separators (190) are disposed in a lumen of the tightening tube (140) in such a manner that they are individually located between the first clip arm (110) and the middle clip arm (150) and between the second clip arm (120) and the middle clip arm (150), thus reducing the risk of device faults caused by interference of the first clip arm (110) and the second clip arm (120) with the middle clip arm (150).
Surgical instruments with non-symmetrical articulation arrangements
A surgical instrument that comprises an elongate shaft assembly that defines a shaft axis. A surgical end effector is pivotally coupled to the elongate shaft assembly for selective pivotal travel relative thereto about an articulation axis that is laterally offset from the shaft axis and extends transversely relative thereto. An end effector driver link is operably coupled to the surgical end effector and an articulation driver that is supported for longitudinal travel in distal and proximal directions upon application of articulation motions thereto. A flexible de-articulation member is coupled to the elongate shaft assembly and the surgical end effector to apply de-articulation motions to the surgical end effector.
Method for creating a flexible staple line
A method for creating a flexible fastener line is disclosed. The fastener line comprises fasteners oriented in directions which are transverse or oblique to a tissue incision created by a cutting member. The fasteners can translate and/or rotate within the tissue when the tissue is stretched thereby creating flexibility within the tissue.
Shape memory implants and a method and apparatus for the loading and implanting thereof
An orthopedic fixation system includes an implant and an implant insertion device. The implant transitions between a natural shape and an insertion shape. The implant includes a bridge defining a slot with a first end and a second end and first and second anchoring members extending from the bridge. The implant insertion device moves between a loaded position and an unloaded position. The implant insertion device in its loaded position inserts through the slot of the bridge and engages the bridge at the first and second ends of the slot such that the implant insertion device constrains the implant in its insertion shape. The implant insertion device in its unloaded position releases the implant.
MULTI-PROCESSING DEVICE FOR AN ENDOSCOPE AND USE METHOD THEREOF
The present disclosure provides a multiple-processing device for an endoscope. The multi-processing device may comprise a plurality of processing units, a conveying component, and an operation component. The processing units may include a capsule body and clamping arms. A proximal end of the capsule body may be provided with a first limit part that may be available for deformation or failure under an external force. The distal end of a conveying pipe of the conveying component and/or the proximal end of the capsule body may be provided with a second limit part configured to expand and contract along a radial direction of the conveying pipe. The multiple-processing device not only enhances the combination between the capsule body and the conveying pip, so as to control the opening and closing of the clamping arms, but also prevents the processing units from interfering or jamming the inner wall of the conveying pipe due to the expanded first limit part, which can ensure the smooth movement of the processing units in the conveying pipe, so that the processing units can be effectively repeatedly opened and closed before being released. The present disclosure also provides a use method of a multi-multi-processing device for an endoscope.
Hemostasis reloadable clip release mechanism
A system for treating tissue includes a clip assembly including clip arms movable relative to a channel of a capsule so that the clip arms are movable between a tissue receiving configuration and a tissue clipping configuration. Also, the system includes an applicator releasably coupleable to the clip assembly. The applicator includes a bushing and a control member extending therethrough. The bushing includes deflectable fingers, each of the fingers including an engaging feature at a distal end thereof to engage a corresponding engaging feature of the capsule of the clip assembly and assembled with a pusher element configured to push the fingers to a radially outward position. The pusher element includes a U-shaped portion curving into a channel of the bushing and a longitudinal portion extending distally therefrom. A cam washer is slidable over a length of the control member and positioned distally of the U-shaped portion.

Absorbable surgical coil fastener
A surgical fastener deployment system may include a plurality of coil fasteners having a head and coil body. In some embodiments, the head is comprised of a bioabsorbable polymer. In one embodiment, the coil body may be comprised of a shell and a core and one of the shell and the core may be comprised of one of a magnesium alloy or a bioabsorbable polymer, and the other of the shell and core is formed of the other of the magnesium alloy and the bioabsorbable polymer. The coil body may also include an internal channel which may have a support coil disposed within.
