Embodiments of devices for converting continuous rotational motion into oscillating motion are disclosed herein. In one embodiment, an oscillation device can include an input shaft that rotates about a first axis, a portion of the input shaft defining an eccentric section that defines a second central axis offset from the first axis, a connector rotatably coupled around the eccentric section, an oscillating shaft offset from the input shaft that rotates about a third axis, and a pin coupled to the oscillating shaft and extending towards the connector. The connector includes a sleeve slidably receiving an end of the pin, and continuous rotation of the input shaft about the first axis causes an eccentric movement of the connector, and the eccentric movement of the connector oscillates the sleeve along the pin and oscillates the pin with respect to the oscillating shaft, thereby oscillating the oscillating shaft about the third axis.

A system for improving graft harvesting including a blade guide (320) having a handle (370) and a guide portion with an elongate slot (330). The system may also include a first blade assembly (750) that slides along the elongate slot (330), the blade assembly (750) having a cutting blade (765) rotatably coupled to a handle (780). The cutting blade (765) may include a leading cutting edge and a trailing cutting edge. The blade assembly (350, 750) and blade guide (320) may cooperate to control a depth of blade penetration into a tissue, as the blade slides along the elongate slot (330). The blade guide (320) may include means to stabilize the guide with the tissue.

A tool is provided in a kit of parts for an implantable penile prosthesis that includes a first tubing section and a first connector that is attachable to a second tubing section and a second connector. The tool has a vertex end and an open end, a first arm extending from the vertex end to a first distal end, and a second arm extending from the vertex end to a second distal end. The first distal end is spaced apart from the second distal end to define the open end of the tool.

A surgical stapling device includes an elongate body and a tool assembly. The elongate body has a distal portion and a proximal portion. The tool assembly is supported on the distal portion of the elongate body and includes a stationary jaw, a top jaw positioned on one side of the stationary jaw, and a bottom jaw positioned on an opposite side of the stationary jaw. The top jaw is movable in relation to the stationary jaw independently of the bottom jaw between an open position and a clamped position to clamp tissue between the top jaw and the stationary jaw, and the bottom jaw is movable in relation to the stationary jaw independently of the top jaw between an open position and a clamped position to clamp tissue between the bottom jaw and the stationary jaw.

A surgical end effector for use with a surgical instrument that includes an elongate shaft assembly that includes a rotary output drive shaft is disclosed. An elongate channel is attached to the elongate shaft assembly. An anvil frame that comprises a proximal end and a distal end is selectively movable between open and closed positions relative to the elongate channel. An anvil concentric drive member is rotatably supported by the anvil frame and is configured to receive rotary drive motions from the rotary output drive shaft of the surgical instrument when the anvil frame is in the closed position. A firing member is in driving engagement with the anvil concentric drive member for linear travel through the end effector.

A handle assembly and a stapler including the same are provided. The handle assembly includes: a first handle component and a second handle, a first end of which is rotatably connected with the first handle component. The handle can be divided into a first handle component and a second handle, and a linkage state of the first handle component and the second handle can be controlled by a moving position of a slider which can be returned by action of a compression spring after the slider is free from a force exerted by the indicator, and a position of the compression spring is defined by a first limiting structure of the slider and a second limiting structure of the first handle component.

A surgical instrument for treating the stomach tissue of a patient is disclosed. The surgical instrument comprises a handle comprising a display, a shaft extending from the handle, and an end effector extending from said shaft. The surgical system comprises a tissue treatment system configured to treat the stomach tissue along a path, an imaging system configured to capture a tissue image of the stomach tissue, and a controller configured to determine an edge of the stomach tissue, generate an image representing at least a portion of the edge of the stomach tissue, and display the image along with at least a portion of the tissue image on the display.

A system for treating tissue of a patient's anatomy at a target site. A localizer generates location data associated with the anatomy. A display unit overlays visual content on the anatomy within a field of view observable by a user. A visualization program on a computing device generates a virtual reference frame, identifies viable and non-viable approaches for fixation elements to engage tissue and secure a stabilizer relative to the target site based on patient-specific imaging data, arranges a virtual viability model within the virtual reference frame based on the location data and comprising viable portions associated with viable approaches and non-viable portions associated with non-viable approaches, and renders the virtual viability model in the visual content displayed by the display unit overlaid onto the anatomy within the field of view to assist the user in visualizing at least one of viable approaches and non-viable approaches.

Methods and devices for catheter-based removal of unwanted tissue or occlusive matter from blood vessels and other body lumens rely on a wire advanced from a tube to deploy a capture net that can be drawn over the clot. Apparatus include simple and reliable mechanisms for deployment of nets, funnels, and other clot capturing mechanisms for retrieving clot material from inside a blood vessel.

A surgical instrument comprising a firing drive and a bailout retraction system is disclosed.
