A robotic system for minimally invasive surgery includes a surgical tool and a docking station for restraining movement of the surgical tool to four degrees of freedom about an incision point in a patient. The docking station includes a plurality of actuators for moving the surgical tool relative to the incision in the patient, and a controller operably connected to the actuators so that movement of the surgical tool may be collaboratively controllable both actively by the controller and manually by a surgeon. Desirably, the surgical tool and the docking station are releasably attachable together. Also disclosed is a computer implemented method employing a first docking station attachable to a suturing surgical tool and a second docking station attachable to gripping surgical tool for autonomously tying a knot in suturing.

A medical system that allows a mentor to teach a pupil how to use a robotically controlled medical instrument. The system may include a first handle that can be controlled by a mentor to move the medical instrument. The system may further have a second handle that can be moved by a pupil to control the same instrument. Deviations between movement of the handles by the mentor and the pupil can be provided as force feedback to the pupil and mentor handles. The force feedback pushes the pupil's hand to correspond with the mentor's handle movement. The force feedback will also push the mentor's hand to provide information to the mentor on pupil's movements. The mentor is thus able to guide the pupil's hands through force feedback of the pupil handles to teach the pupil how to use the system.

An access and cannulation device includes a mounting element such as the anastomosis mounting element disclosed in U.S. application Ser. No. 08/714,615 (now U.S. Pat. No. 5,868,763) and U.S. application Ser. No. 09/200,796. The device is used to provide access therethrough and via an incision to the interior of a hollow anatomical structure such as a vessel, an organ or the like during surgery, especially minimally invasive surgery. It includes a flexible sleeve with a suture therein for closing the sleeve and locating edges of the structure adjacent to the incision in position for proper healing after completion of a surgical procedure. A tool is also disclosed for manipulating the device to configure it for the surgery and to close it after completion of the surgery whereby the edges of the wall of the structure adjacent to an incision are approximated to promote proper healing.

A single body port or body flange access device having an oval shape and associated stabilizer anchor for performing laparoscopic surgery is disclosed. The device is slipped into the body anchor stabilizer first so that the anchor stabilizer lifts up fat and peritoneum inside the body thereby keeping the operating area clear and acting to hold the body flange in place. The device further has a plurality of crisscrossing conduits assuming the shape of a cone 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. Due the oval shape of the device, the device minimally rotates while instruments are manipulated.

An annuloplasty repair segment and template for heart valve annulus repair. The elongate flexible template may form a distal part of a holder that also has a proximal handle. Alternatively, the template may be releasably attached to a mandrel that slides within a delivery sheath, the template being released from the end of the sheath to enable manipulation by a surgeon. A tether connecting the template and mandrel may also be provided. The template may be elastic, temperature responsive, or multiple linked segments. The template may be aligned with the handle and form a two- or three-dimensional curve out of alignment with the handle such that the annuloplasty repair segment attached thereto conforms to the curve. The template may be actively or passively converted between its straight and curved positions. The combined holder and ring is especially suited for minimally-invasive surgeries in which the combination is delivered to an implantation site through a small access incision with or without a cannula, or through a catheter passed though the patient's vasculature.

An imaging system is provided for use with minimally invasive surgery. The imaging system comprises a platform which is anchored to a wall of a patient cavity. The platform comprises a plurality of transceivers which transmit energy toward the surgical site and receive reflected energy. The transceivers transmit rasterized image information to a computer which then displays the image information in real time, enabling a surgeon to view the surgical site on a display device. The transceivers can transmit and receive different types of energy, and the computer can then combine image information from the various different energy types to provide overlaid images of the surgical site. In addition, the computer controls the relative positions of the transceivers so that the images provided to the surgeon will not be affected by movement of the platform or by movement of structures (i.e., organs) at the surgical site.

Medical software tools platform utilizes a surgical display to provide access to specific medical software tools, such as medically-oriented applications or tools, that can assist those in the operating room, such as a surgeon or surgical team, with a surgery. In particular, an optical sensor located within an endoscopic camera may register subtle differences in color characteristics reflected from a tissue surface and in turn transmit the information to a medical image processing system. Moreover, the new tools are intended to help surgeons better determine the boundaries between healthy and diseased regions during surgical procedures. Various tools are intended to be used in procedures where indocyanine green (ICG) fluorescent dye is used. Intraoperative fluorescence imaging is commonly used during minimally invasive procedures to enable surgeons to visualize tissue perfusion and anatomical structures. The term perfusion refers to the passage of blood and tissue fluid through the capillary bed. Intraoperative fluorescence imaging can also be used to improve visualization of vessels and structures, which, in turn, may reduce the risk of complications during minimally invasive surgeries.

Further, a reconfigurable tip is configured to be in an entry state and a visualization state. Said aspects and associated method steps can significantly reduce the complexity of the entry process and do not require removal and reinsertion of surgical instruments which eliminates the need for valves in the trocar and reduces the possibility of contamination of the visualization means' objective lens.
