Actuator retainer for surgical stapler
A surgical stapler includes a first elongate member, a second elongate member, a clamp member, and a firing assembly. The first elongate member includes a distal portion that supports an anvil surface that includes a plurality of staple forming pockets. The second elongate member includes a distal portion that is configured to receive a staple cartridge. The clamp member is operable to releasably clamp the first elongate member against the second elongate member. The firing assembly is translatable from a first longitudinal position to a second longitudinal position to fire the staple cartridge. The firing assembly includes a slider and an actuator. The slider includes a first coupling feature. The actuator is configured to be selectively actuated by a user. The actuator includes a second coupling feature that is configured to generally surround the first coupling feature of the slider when the actuator moves relative to the slider.
Implant and suture organization device
An organization device for maintaining a suspensory graft fixation device (i.e., an implant and suture) in a desired position. The device includes a substrate having top and bottom edges with first and second panels extending therebetween. The device also includes a first central longitudinal axis extending in a direction from the top edge to the bottom edge between the first and second panels. The first and second panels are foldable about the axis between open and closed positions. The device also includes an opening extending through the bottom edge and into the first panel, and a plurality of top slits and bottom slits. The plurality of top slits includes at least one top slit which is aligned with the first opening. The device additionally includes a tabs adjacent the opening. The slits and tabs are configured to maintain suture of a suspensory graft fixation device in an organized manner.
Offset Hohmann
A surgical retractor tool includes a handle and a blade extending transversely from a front end of the handle. The blade includes a proximal portion and a distal portion with respective proximal and distal tissue engaging surfaces. The distal tissue engaging surface may be skewed relative to the proximal tissue engaging surface such that the handle may be angled relative to a direction of retraction when the surgical retractor tool is used. A distal tip of the retractor may include a curved tongue that may be curved in a direction opposite the direction of retraction.
Anchor delivery systems
Anchor delivery systems include markings on the surfaces of the delivery device which are visually exposed to the user through openings or fenestrations in the anchor, providing visual feedback to the user on the progress of the anchor's insertion. A suture-locking plug is deformable within the anchor tip, thereby enhancing suture entrapment within the tip of the anchor. A compliant component of the handle places the handle components in tension, thereby absorbing built-in axial looseness in the handle. The handle further includes a spin cavity which allows for free spin of the inserter shaft to finalize insertion of the anchor into bone when the anchor has not been fully seated flush with or below the cortical bone surface.
Surgical stapler with reversible polarity
A method for resetting a stapling apparatus includes providing an apparatus with a cam member in a fired position. A circuit of the apparatus is then changed from a first polarity state to a second polarity state. A motor of the apparatus is then activated to rotate the cam member from a fired position back to a home position while the circuit is in the second polarity state.
Drill guide with integrated variable angle and zero degree drilling
A drill guide, including: frustoconical body with a first opening at a narrower distal end and second opening at a wider the proximal end; a first support with a first end connected to the frustoconical body and a second end; a zero angle guide with an opening aligned with the first opening and wherein the zero angle guide is connected to the second end of the first support.
Surgical instrument having force feedback capabilities
A surgical instrument. The surgical instrument has a force delivery system which communicates a changing force to a user of the surgical instrument when a limit of a surgical function is reached. A sensor senses position of a moving element to communicate a signal to the force delivery system. In various embodiments, the system generates a vibratory force to signal the user.
Patella clamp
Disclosed herein is a patella clamp configured to grip a patient's patella. The patella clamp includes a clamping assembly, a ratchet arm assembly, and a handle assembly. The clamping assembly includes first and second patella grip portions mounted in opposing relationship. In use, actuation of the handle assembly moves the second patella grip portion towards the first patella grip portion to clamp the patient's patella. The handle assembly is configured to be moveably adjustable (e.g., rotatable) relative to the clamping assembly. For example, each of the first and second patella grip portions are coupled to mating features mounted on the ratchet arm assembly. Decoupling of the mating features allows the first and second patella grip portions to rotate about the longitudinal axis of the ratchet arm assembly. Thus arranged, the patella clamp is configured to enable the surgeon to reposition the handle assembly to provide increased visibility, etc.
SYSTEMS AND METHODS FOR EMBOLIC IMPLANT DEPLOYMENT
An aneurysm treatment system can include an embolic implant, a delivery system, and a handle member that are collectively designed so that the combination of the handle member and the delivery system can be used as a deployment apparatus for the embolic implant. A proximal extension of the delivery tube can be placed inside a handle channel of handle member and the handle member can be manipulated to cause the proximal extension to bend to a predetermined angle with respect to the delivery tube, thereby separating the proximal extension from the delivery tube at a disconnection feature between the proximal extension and the delivery tube. The delivery tube includes a lumen having a pull wire that runs through the delivery tube and into the proximal extension. The proximal extension, pull wire, and handle member can be translated proximally in relation to the delivery tube to deploy the embolic implant.
BONE SCREW
A bone screw, such as a pedicle screw, comprises an anchor portion and a sleeve portion, the anchor portion including an angled or curved portion and an externally threaded portion. The sleeve portion having an external thread for engaging bone, and a threaded internal bore for engaging the externally threaded portion of the anchor portion.
