  • Patent number: 9119654
    Abstract: Surgical methods and devices allow closed-chest surgery to be performed on a heart of a patient while the heart is beating. A region of the heart is stabilized by engaging a surface of the heart with a stabilizer without having to stop the heart. Motion of the target tissues is inhibited sufficiently to treat the target tissues with robotic surgical tools which move in response to inputs of a robotic system operator. A stabilizing surface of the stabilizer is coupled to a drive system to position the surface from outside the patient, preferably by actuators of the robotic servomechanism. Exemplary stabilizers includes a suture or other flexible tension member spanning between a pair of jointed bodies, allowing the member to occlude a coronary blood vessel and/or help stabilize the target region between the stabilizing surfaces.

  • Patent number: 8914150
    Abstract: Improved robotic surgical systems, devices, and methods include selectably associatable master/slave pairs, often having more manipulator arms than will be moved simultaneously by the two hands of a surgeon. Four manipulator arms can support an image capture device, a left hand tissue manipulation tool, a right hand tissue manipulation tool, and a fourth surgical instrument, particularly for stabilizing, retracting, tool change, or other functions benefiting from intermittent movement. The four or more arms may sequentially be controlled by left and right master input control devices. The fourth arm may be used to support another image capture device, and control of some or all of the arms may be transferred back-and-forth between the operator and an assistant. Two or more robotic systems each having master controls and slave manipulators may be coupled to enable cooperative surgery between two or more operators.

  • Patent number: 8870900
    Abstract: Devices, systems and methods related to endoscopic surgery, particularly related to robotic surgical operations, provide a tissue stabilizer for endoscopically stabilizing a target tissue within a patient's body. For stabilizing a beating heart during a closed-chest coronary artery bypass grafting procedure, a stabilizer is inserted through an endoscopic cannula and provides sufficient surface area to contact the heart and effectively stabilize the target tissue area. The stabilizer can straddle a blood vessel, such as a coronary artery, which is targeted for an anastomosis. Vessel occlusion fasteners may occlude the target blood vessel prior to the anastomosis procedure.

  • Patent number: 8600551
    Abstract: A medical robotic system has a surgeon console which is operatively couplable to a patient side unit for performing medical procedures or operatively couplable to a simulator unit for training purposes. The surgeon console has a monitor, input devices and foot pedals. The patient side unit has robotic arm assemblies coupled to instruments and an endoscope. When the surgeon console is coupled to the patient side unit, the instruments move in response to movement of the input devices to perform a medical procedure while captured images of the instruments are displayed on the monitor. When the surgeon console is coupled to the simulator unit, virtual instruments move in response to movement of the input devices to perform a user selected virtual procedure while virtual images of the virtual instruments are displayed on the monitor.

  • Patent number: 6858003
    Abstract: A surgical system or assembly for performing cardiac surgery includes a surgical instrument; a servo-mechanical system engaged to the surgical instrument for operating the surgical instrument; and an attachment assembly for removing at least one degree of movement from a moving surgical cardiac worksite to produce a resultant surgical cardiac worksite. The surgical system or assembly also includes a motion tracking system for gathering movement information on a resultant surgical cardiac worksite. A control computer is engaged to the attachment assembly and to the motion tracking system and to the servo-mechanical system for controlling movement of the attachment assembly and for feeding gathered information to the servo-mechanical system for moving the surgical instrument in unison with the resultant surgical cardiac worksite such that a relative position of the moving surgical instrument with respect to the resultant surgical cardiac worksite is generally constant.

  • Patent number: 6837883
    Abstract: Improved robotic surgical systems, devices, and methods often include a first assembly with a surgical end effector supported and manipulated relative to a first base by a first robotic linkage, while a second surgical end effector manipulated and supported relative to a second, independent base by a second robotic linkage. One or more of these robotic assemblies may be moved relative to the other. To coordinate the end effector movements with those of input devices being manipulated by a surgeon relative to a display of a surgical worksite, the processor deriving the commands for movement of the robotic linkages may make use of a signal indicating a relative orientation of the bases of the robotic arm assemblies. Surprisingly, the robotic arm assemblies may not transmit signals to the processor indicating a relative translational position of the bases.

  • Patent number: 6770081
    Abstract: Surgical accessories are presented in vivo and used by surgical tools in the surgical site to perform additional tasks without the need to remove the tools from the surgical site for tool change or instrument loading. Some accessories need to be actuated to effect a predetermined treatment, such as an aortic punch, clamps, pliers, and the like. For such accessories, the actuation can conveniently be performed by an operator such as an assistant remotely from outside the patient's body while placement of the accessories takes place in the surgical site by manipulating the accessories using robotic surgical tools in the site. A lockdown feature may be incorporated in accessories to lock them in place remotely from outside the surgical site upon actuation.
