A surgical stapling system for stapling the tissue of a patient is disclosed. The stapling system comprises a housing, a shaft extending from the housing, and an end effector extending from the shaft. The end effector comprises a plurality of staples removably stored therein and, also, an anvil configured to deform the staples. The stapling system further comprises a firing mechanism configured to deploy the staples along a staple firing path longer than 60 mm, a camera configured to capture an image of the patient tissue, a display, and a controller configured to generate an image of the staple firing path, wherein the images are displayed on the display.

A powered surgical handpiece including a housing, a printed circuit board, a sensor, and an actuator assembly. The housing has a longitudinal axis extending from a first end to a second end of the housing. The printed circuit board has a first face and a second opposing face. The first and second faces extend perpendicular to the longitudinal axis. The sensor is coupled to the first face of the printed circuit board. The sensor is centered along the longitudinal axis of the housing. The actuator assembly includes a lever and an actuator. The lever is pivotally coupled to the housing. The lever maintains a magnet slidably positionable along the lever. The magnet is positionable to be proximal to the sensors.

A suture transport system is disclosure for placing a flexible member along a tunnel, the system including a means of transporting a flexible member along a tunnel from a first opening in the tunnel through to a second opening at an opposite end of the tunnel, such that the flexible member extends from both the first and second opening. The system also includes a means of capturing a portion of the flexible member at the second opening, to inhibit the flexible member from retracting into the tunnel second opening. The means of capturing includes an aperture for capturing the portion of the flexible member.

The shaft-type instrument (1) has a shaft part (2), fixedly connected at one end to a shaft grip (3), and a sliding part (4). The sliding part (4) is displaceably mounted relative to the shaft part (2) and is, at one end, in operative connection with a pretensioned handgrip (5) such that by actuating the handgrip (5), the sliding part (4) is displaceable counter to the pretension. A respective lever arm (7, 7′) is articulated at two spaced apart shaft articulation points (6, 6′) on the shaft part (2) or shaft grip (3). The handgrip (5) has a coupling section (8) which connects the lever arms (7, 7′) and coupling joints (9, 9′) to one another such that same can pivot in the same direction. The coupling joints are spaced apart and a grip section (10) extends transverse to the coupling section (8) and to the shaft part (2).

A surgical stapler can comprise an anvil comprising a staple pocket formed in a tissue contacting surface. The staple pocket can comprise a midline or centerline, a first forming cup, and a second forming cup. The first forming cup can comprise a first interior sidewall comprising a first vertical portion which is substantially perpendicular to the tissue contacting surface. The second forming cup can comprise a second interior sidewall comprising a second vertical portion which is substantially perpendicular to the tissue contacting surface. The first vertical portion and the second vertical portion can extend through the centerline, wherein the first interior sidewall and the second interior sidewall can comprise a trap for deforming a first staple leg of a staple to a first side of the centerline and for deforming a second staple leg of the staple to a second side of the centerline.

A medical instrument includes a handle, a trocar in communication with the handle, and a cannula in communication with the trocar and the handle. The cannula is engaged (locked) with the handle when linearly displaced proximally towards the handle and, the cannula is disengaged (unlocked) from the handle when linearly displaced distally away from the handle. The cannula is linearly reciprocated, between the locked position and the unlocked position, along a linear travel path defined parallel to a longitudinal axis of the trocar such that the cannula is prohibited and permitted to articulate about the longitudinal axis of the trocar, and relative to the handle, respectively. Advantageously, the cannula is locked and unlocked from the trocar by without requiring an external force exerted generally transverse to trocar and/or cannula—thereby permitting a user to lock/unlock the cannula, relative to the trocar, with one hand.

A method, apparatus, and system for cutting anatomic members, such as ligaments, in surgical procedures such as carpal tunnel release, plantar fasciotomy, gastroc release, cubital tunnel release, and tarsal tunnel release is disclosed. The apparatus includes a guide tool for guiding a knife and a scope during surgery which may be employed with a translating knife. Relevant features include a knife stop for preventing the knife from inadvertently raising out of the knife channel, indicia viewable to show the proper orientation for the guide tool, a self dilating tip and channel design on the guide tool, a cover piece and/or pivotable panel system for preventing ligaments and other anatomy from getting caught in the guide tool, a pivot pin and groove system for stabilizing the knife and also assuring that the knife blade is not inadvertently raised out of the channel, and a use indicator employable to prevent re-use of the device.

A tissue retrieval system including a tissue retrieval bag deployable from an introducer and suspended in an open configuration by support arms can include retention features to prevent inadvertent movement of the tissue retrieval bag relative to the support arms. The support arms can include protruding domes, folds, or curls to restrict sliding of the tissue retrieval bag relative to the support arms. Alternately, tension can be maintained in a cord loop coupled to an opening of the tissue retrieval bag to prevent the tissue retrieval bag from inadvertently sliding relative to the support arms.

A system includes a handpiece and a removable tool assembly including a holder body, a shaft, a medical tool, a guard, and a sleeve. The body engages the handpiece and defines a bore. The shaft extends within the bore and the tool is provided to the distal end of the shaft. The guard is coupled to the body via a snap fit connection at the bore and may be friction fit to a bearing sleeve located between the guard and the shaft, such that longitudinal translation of the guard relative to the body longitudinally displaces the guard. The shaft extends within the bore of the body and the guard. The guard is positioned relative to the body by a distance to define a working length of the tool between the distal end of the guard and the distal tip of the tool. The working length of the tool may be used to cut tissue, without concern that cutting will be deeper than intended.

An applicator instrument for dispensing surgical fasteners includes a housing, and an elongated shaft extending from the housing. The elongated shaft has a proximal end secured to the housing, a distal end spaced from the proximal end, and a first axis extending between the proximal and distal ends of the elongated shaft. Surgical fasteners are disposed in the elongated shaft. The surgical fasteners are stacked at an angle relative to the first axis of the elongated shaft. A distal end cap having a surgical fastener dispensing window is secured to the distal end of the elongated shaft. The applicator instrument has a firing system disposed in the housing, and an actuator coupled with the firing system for activating the firing system to dispense the surgical fasteners through the surgical fastener dispensing window.
