摘要:
A system for deploying needles in tissue includes a controller and a visual display. A treatment probe has both a needle and tines deployable from the needle which may be advanced into the tissue. The treatment probe also has adjustable stops which control the deployed positions of both the needle and the tines. The adjustable stops are coupled to the controller so that the virtual treatment and safety boundaries resulting from the treatment can be presented on the visual display prior to actual deployment of the system.

Ablation devices and associated methods are provided for use in ablating the margin of a cavity such as a surgical or body cavity. The ablation apparatus includes an integral or connected elongate probe and an elongate sleeve. Suction can be applied with a vacuum source operably connected to the proximal end region of the sleeve, whereby tissue of the surgical cavity is drawn against the surface of the sleeve. The probe includes one or more electrodes disposed at the probe's distal end region, for ablating tissue when the electrode(s) are activated to create an ablated margin of tissue at least partially surrounding the surgical cavity.

Radiosurgical treatments of tissues of the heart mitigate arrhythmias and treat other tumerous and non-tumerous disease using an implanted fiducial positioned in or near the heart using cardiac catheterization techniques. The fiducials may be implanted after diagnostic and planning images of the target tissues have been acquired. Fiducial implantation may take place the day of a scheduled radiosurgical treatment. Techniques to accommodate post-planning fiducial implantation may include registration of the implanted fiducial location with the treatment plan, and active fiducials may limit collateral imaging radiation exposure while enhancing tracking accuracy.

A handle used to control movement of a medical instrument. The medical instrument may be coupled to a robotic aim that is connected to a controller. The medical instrument may have a plurality of functions such as wrist locking and motion scaling. One of the functions may be selected through a graphical user interface operated by the end user. The handle may have a plurality of buttons. One of the buttons may allow the end user to control the selected function. For example, when wrist locking/unlocking is selected, depressing the button can toggle the medical instrument wrist between a locked state and an unlocked state.

A system for performing minimally invasive cardiac procedures includes a pair of surgical instruments coupled to a pair of robotic arms with end effectors that can be manipulated to hold and suture tissue. The robotic arms are coupled to a pair of master handles by a controller to produce a corresponding movement of the end effectors. The movement of the handles is scaled such that the end effectors movement corresponds differently, typically smaller, than the movement performed by the hands of the surgeon. The input button allows the surgeon to adjust the position of the handles without moving the end effector, so that the handles can be moved to a more comfortable position. The system may include a robotically controlled endoscope allowing the surgeon to remotely view a surgical site. The surgeon may manipulate handles and move end effectors to perform a cardiac procedure.
摘要:
A robotic system which controls the movement of a surgical instrument in response to voice commands from the user. The robotic system has a computer controlled arm that holds the surgical instrument. The user provides voice commands to the computer through a microphone. The computer contains a phrase recognizer that matches the user' speech with words stored in the computer. Matched words are then processed to determine whether the user has spoken a robot command. If the user has spoken a recognized robot command the computer will move the robotic arm in accordance with the command.
