A surgical tool including a socket having a housing and an aperture within the housing, the socket configured to receive a ball and a pin at least partially in the aperture. The ball is positioned at least partially in the socket and configured to rotate within the socket, the ball comprising an elongated opening extending through the ball. The pin is coupled to the socket and disposed at least partially in the socket on opposite sides of the socket, the pin including a first longitudinal axis and extending through the elongated opening of the ball between opposite sides of the socket. The ball is configured to partially rotate about the first longitudinal axis of the pin, and partially rotate, about a second axis perpendicular to the first longitudinal axis of the pin, in a plane aligned with the elongated opening.

Surgical instruments with articulatable surgical end effectors and rotary driven flexible drive members.

An articulating rotary cutting tool configured to articulate a distal cutting tip upon a trigger being operated. The trigger can be locked into various articulating positions. The velocity of rotation of a cutting bit is substantially constant in both articulating and non-articulating positions. An articulation joint is one of a hex ball joint or a flexible spring joint. A button is included to release a locking pressure holding the trigger in a locked position. The trigger may employ articulating sliding surfaces that provide constraint to a flexed head in both directions of articulation.

Devices, methods and systems are provided for occluding an opening within the tissue of a body, such as a left atrial appendage. In one embodiment, a delivery system for use in occluding an opening in the tissue of a body includes an actuation assembly operatively coupled to a medical device including an anchor portion and an occluder portion. The actuation assembly is configured to move the anchor portion between a deployed state and retracted state while the occluder portion maintains a deployed state. With this arrangement, the deployed occluder portion can be visualized via imaging at a preferred position prior to deploying the anchor portion of the medical device.

The present invention provides an orthopaedic reamer handle that includes a reamer portion configured to transmit torque to a reamer head, a driver portion connected to the reamer portion that is configured to receive and transmit torque from a driver, and a drive train connecting the reamer portion to the driver portion to transmit torque from the driver portion to the reamer portion. The drive train includes a first drive shaft that defines a first axis and is connected to the driver portion at a first end and to a first intermediate connector at a second end. An offsetting member is connected to a second intermediate end of the first intermediate connector at an acute angle relative to the first axis and defines a second axis. The offsetting member connects to the reamer portion via a second intermediate connector at an acute angle relative to the second axis.

A bone screw tightening device including a screw driver, the screw driver having along its axis a device for providing for radial bendability and at a same time preserving torsional stiffness along an axis of longitudinal extension of the screw.

Multi-axis pivot joints and surgical instrument drive shafts formed using additive manufacturing methods.

An instrument positioning mechanism includes a mounting position (125) on a medical device having a channel configured to permit an instrument (104) to pass therethrough. An instrument support (146) is configured to support a length of the instrument. A pivotal connection (150) is configured to rotatably adjust an angle between the support and the mounting position.

Surgical instruments that include an articulation joint that is a configured to establish an upper pathway and a lower pathway through the articulation joint. The upper pathway and the lower pathway are parallel to each other when the surgical instrument is in an unarticulated position and the upper pathway and the lower pathway are concentric to each other when the surgical instrument is articulated. An upper flexible firing assembly slidably extends through the upper pathway and a lower flexible firing assembly slidably extends through the lower pathway. The upper and lower flexible firing assemblies interface with a firing member and a differential drive assembly configured to apply axial drive motions to the upper flexible firing assembly and the lower flexible firing assembly.
