An electromechanical surgical system having an instrument housing for connecting with a shaft assembly, a shaft assembly, and an end effector. The end effector is an articulating end effector and the system includes a cable tensioning system for tensioning the articulation cables. The system includes a clutch mechanism for preventing slippage of a drive cable.

The exoskeleton (10) for assisting surgical positioning is made of biocompatible material and formed to be substantially form-preserving. The exoskeleton (10) comprises a shell (11) having a coupling surface (15b) fitting to at least a part of a surface of an organ to be operated, and a guiding channel (13) is formed in the shell (11) at a predetermined position, said guiding channel having a predetermined orientation with respect to said shell and a predetermined cross-sectional area for directing a surgical tool to the organ to be operated.

A surgical stapling apparatus includes a staple cartridge and an anvil member. The staple cartridge includes a plurality of surgical fasteners disposed in rows of retention slots. The staple cartridge may have an annular or linear configuration of retention slots. The tissue contacting surface of the staple cartridge may be tapered or stepped. The anvil member has a tissue contacting surface that includes a number of pockets arranged for substantially aligning with the retention slots. In addition, the tissue contacting surface of the anvil member may complement the tissue contacting surface of the staple cartridge.

A forceps having at least a first jaw with a longitudinal axis is disclosed. The first jaw can include a body portion, a first flange, a second flange and a cam pin. The first flange can define a first cam slot with a longitudinal extent along the longitudinal axis. The second flange can be spaced from the first flange a distance transverse to the longitudinal axis of the first jaw and can have a second cam slot. The cam pin, with a longitudinal axis, can be moveably secured within the first cam slot and the second cam slot. A diameter of the cam pin can be less than a width between a first longitudinal edge that defines a first side of each of the first cam slot and the second cam slot and a second longitudinal edge that defines a second opposing side of each of the first cam slot and the second cam slot so that the cam pin is moveably received by both the first cam slot and the second cam slot. With the first jaw pivoted to at least a first position, the cam pin and first flange can be configured such that the first longitudinal edge is contacted by the cam pin but the second longitudinal edge is spaced from the cam pin. The cam pin and second flange can be configured such that the first longitudinal edge is spaced from the cam pin but the second longitudinal edge is contacted by the cam pin.

A medical device to effectively remove an object, like an intravascular thrombus, in a body lumen includes: a rotatable tubular driving shaft; a cutting part that is provided on a distal side of the driving shaft, rotates together with the driving shaft, and cuts the thrombus; and a second cutting part that is disposed near the distal side of the driving shaft, inward of the cutting part.

A number of improvements are provided relating to computer aided surgery. The improvement relates to both the methods used during computer aided surgery and the devices used during such procedures. Some of the improvement relate to controlling the selection of which data to display during a procedure and/or how the data is displayed to aid the surgeon. Other improvements relate to the structure of the tools used during a procedure and how the tools can be controlled automatically to improve the efficiency of the procedure. Still other improvements relate to methods of providing feedback during a procedure to improve either the efficiency or quality, or both, for a procedure.

A modular surgical apparatus is disclosed. Also disclosed is a modular incision apparatus. The modular incision apparatus may be used in a minimally invasive surgery. The modular incision apparatus includes a base having a pair of pivots, a pair of alignment tabs, a proximal opening, and at least one slide guide. The modular incision apparatus includes visual and cleaning access to the blade. The modular incision apparatus is suitable for safely, efficiently, and accurately making small incisions during surgical procedures. The modular incision apparatus provides a means of making small incisions of controlled depth, while reducing the chances of inadvertent exposure of surgical staff to sharp instrument.

An apparatus for explanting an intracardiac medical device that comprises a casing, a proximal end and a distal end comprising an anchor element, wherein the intracardiac medical device is anchored to a heart tissue of a patient via the anchor element, wherein heart tissue adheres to the casing. The apparatus comprises a protector device that extends along an extension direction and is configured to surround the casing, when the protector device is positioned at the casing. Further, the apparatus comprises an alignment device configured to align the protector device and the casing with each other, when the alignment device engages the intracardiac medical device. The apparatus also comprises a shearing element. The shearing element is configured to move along the casing, when the protector device is moved along the casing in a moving direction towards the distal end, for shearing off heart tissue adhered to the casing.

Auxiliary marking plates for rapidly manufactured parts are disclosed. An auxiliary marking plate is configured to provide a surface for displaying user-readable text or other markings with higher resolution. The surface may include a larger surface area than is otherwise available on the rapidly manufactured part. The auxiliary marking plate may be manufactured as part of, substantially at the same time as, or separately from the rapidly manufactured part with which it is associated. The auxiliary marking plate may have a shape that assists with placement of the associated part and may be removable from the part during or after placement. In particular, the auxiliary marking plate may be used with a medical device or instrument and include markings that assists with the performance of a surgical procedure.

A system and method for providing image guidance for placement of one or more medical devices at a target location. The system can determine one or more intersections between a medical device and an image region based at least in part on first emplacement data and second emplacement data. Using the determined intersections, the system can cause one or more displays to display perspective views of image guidance cues, including an intersection ghost in a virtual 3D space.
