The invention relates to an instrument for surgery, in particular minimally invasive surgery. The instrument includes means for feeding back a force which is exerted on the working element of the instrument to the operating element. These means include at least a first force sensor for measuring the force which is exerted on the working element, a control unit and a first actuator. On the basis of a signal which originates from the first force sensor, the control unit controls at least the first actuator in order to control the operating element. Furthermore, the means preferably include a first position sensor for measuring a position of the working element with respect to the frame. The control unit advantageously determines an impedance which the working element is subject to as a result of the presence of a tissue or the like, on the basis of which impedance the control unit controls at least the first actuator.

The instrument tip is bendable toward the shank and carries a mouth part. The surgical instrument also includes a gear mechanism which transforms at least a movement of said actuating device by an operator into a rotation of said mouth part according to a predetermined transmission ratio in relation to the actuating movement.

The present invention provides a micro-robot for use inside the body during minimally-invasive surgery. The micro-robot includes an imaging devices, a manipulator, and in some embodiments a sensor.

Systems and methods are provided for detecting failure in clamping of a material and / or firing of a staple into a clamped material and indicating such failure to a user on a user interface. The system and methods are particularly suited for use with end effectors having closing and / or firing mechanisms coupled to an actuator. By monitoring a driving parameter of an actuator that effects the clamping and / or firing, the systems and methods provide an indication of failure in response to the monitored drive parameter. In some embodiments, an indication of failure is output when the monitored drive parameter is outside an acceptable range of desired driving parameters during clamping and / or firing. The disclosed systems and methods are particularly beneficial when used for minimally invasive surgery.

End effectors with redundant closing mechanisms, and related tools and methods are disclosed. The disclosed end effectors may be particularly beneficial when used for minimally invasive surgery. An example surgical tool comprises an elongate shaft having a proximal end and a distal end, a tool body disposed at the distal end of the shaft, a jaw movable relative to the tool body between a clamped configuration and an open configuration, a first actuation mechanism coupled with the jaw and operable to vary the position of the jaw relative to the tool body between the clamped configuration and the open configuration, and a second actuation mechanism coupled with the jaw. The second actuation mechanism has a first configuration where the jaw is held in the clamped configuration and a second configuration where the position of the jaw relative to the tool body is unconstrained by the second actuation mechanism.

Stent-valves (e.g., single-stent-valves and double-stent-valves), associated methods and systems for their delivery via minimally-invasive surgery, and guide-wire compatible closure devices for sealing access orifices are provided.

A manipulator includes a control unit (1), with handle (4) and control buttons (4a-4d), and a connecting arm (2) which, at its proximal end (2a), carries the control unit (1) and, at its distal end (2b), carries a work unit (3). The control buttons (4a-4d) control at least a first inclination motor, which causes a movement of inclination of a tool support (5) of the work unit (3) about a transverse inclination axis (11), and they control the actual rotation of the tool support (5) about its direction of inclination (II) and control the orientation of the direction of inclination (II) about the longitudinal axis (I-I) of the connecting arm (2). A particularly ergonomic manipulator is thus obtained which is easy to learn to use and which efficiently separates the stresses arising from movements of the tool support (5) and the stresses arising from holding and moving the manipulator itself.

The present device relates to a laparoscopic medical instrument, particularly those used for minimally invasive surgery. The instrument has a movable and a stationary handle portion and an extended shaft assembly with a removable actuating rod. An opening on the side of the stationary handle portion allows a user to visually confirm the removable actuating rod is locked into place within the movable handle portion. An opening in the back of the stationary handle portion allows for cleaning and visual inspection of the interior of the shaft assembly portion once the rod is removed. The actuating rod has a grasping mechanism for performing work during surgery. A flush port is located near the distal end of the stationary handle portion.

A medical tool comprising an electromechanical driver and a surgical instrument attachment for use in invasive surgery, including a handle coupled to a flexible sheath which is in turn coupled to a surgical attachment. The handle of the driver includes the electromechanical driver and at least one processor element which controls the actions of the electromechanical driver, and therefore the application elements of the surgical attachment, based on information relayed between the processor element and remotely activatable sensor assemblies in the surgical instrument attachment.

A patient-side surgeon interface provides enhanced capabilities in using a minimally invasive, teleoperated surgical system. The patient-side surgeon interface has components within the sterile surgical field of the surgery. The components allow a surgeon to control teleoperated slave surgical instruments from within the sterile surgical field. The patient-side surgeon interface permits a surgeon to be in the sterile surgical field adjacent a patient undergoing surgery. Controlling minimally invasive slave surgical instruments from within the sterile surgical field permits minimally invasive surgery combined with direct visualization by the surgeon. The proximity to the patient allows the surgeon to control a teleoperated slave surgical instrument in tandem with controlling manually controlled instruments such as a laparoscopic instrument. Also, the surgeon, from within the sterile surgical field, can use the patient-side surgeon interface to control at least one proxy visual in proctoring another surgeon.

Stent-valves (e.g., single-stent-valves and double-stent-valves), associated methods and systems for their delivery via minimally-invasive surgery, and guide-wire compatible closure devices for sealing access orifices are provided.

A single body port or body flange access device and method for performing laparoscopic surgery are disclosed. The device comprises a plurality of crisscrossing conduits through which surgical instruments may be inserted. The instruments are manipulated so that triangulation is obtained using one patient body flange while standard surgical procedures are performed on the patient.

Wire fasteners having legs with lengths that can be one hundred times the width of the fastener are used to secure items, such as prosthesis valves to a patient during minimally invasive surgery. The fasteners are manipulated into position and then are immobilized by means of the legs thereof for tensioning, cutting and forming in situ. The fasteners are manipulated, tensioned and formed from the leg end of the fasteners. Tools for initially placing the fasteners and for immobilizing, tensioning, cutting and bending the fastener legs are disclosed. Once the fasteners are initially placed, the prosthesis is placed on the long legs of the placed fasteners and is guided into position on the legs. Once the prosthesis is in position, the legs of the fasteners are immobilized, tensioned, cut and bent into staple-like shapes to secure the prosthesis to the patient. A method for carrying out the procedure using the long fastener is also disclosed. Using the teaching of the present disclosure, a surgeon can customize a fastener to the particular surgery or even to the particular portion of surgery being performed during the surgery.

A multi-user medical robotic system for collaboration or training in minimally invasive surgical procedures includes first and second master input devices, a first slave robotic mechanism, and at least one processor configured to generate a first slave command for the first slave robotic mechanism by switchably using one or both of a first command indicative of manipulation of the first master input device by a first user and a second command indicative of manipulation of the second master input device by a second user. To facilitate the collaboration or training, both first and second users communicate with each other through an audio system and see the minimally invasive surgery site on first and second displays respectively viewable by the first and second users.
