Method and system for video based image detection/identification analysis for fluid and visualization control
First Claim
1. A video based image detection/identification system for fluid and visualization control of a laparoscopic surgical system for providing an acceptable video image of a surgical site, comprising:
- a cauterizing tool for manipulating tissue at the surgical site;
an insufflator for providing gas to the surgical site;
an adjustable suction system for providing suction at the surgical site for controlling removal of gas from the surgical site;
a light source for providing light to the surgical site;
a video sensing device for obtaining video signals of video images at the surgical site;
an image display for displaying the video images; and
a system controller configured to maintain quality of the video images obtained by the video sensing device and provided to the image display, wherein the system controller receives and processes the video signals to identify a video signature corresponding to a condition that interferes with a quality of the video images;
the system controller interacting with the cauterizing tool, the insufflator and the adjustable suction system and controlling at least one of the cauterizing tool, the insufflator and the adjustable suction system to address the condition of the surgical site to return the video images from the video signals to an acceptable quality for viewing so that a user is free from having to manually control any of the cauterizing tool, the insufflator, the adjustable suction system, and the video sensing device to obtain the acceptable video image of the surgical site for viewing on the image display;
wherein the video signature to be identified comprises smoke, and the system controller operates at least one of the cauterizing tool, the insufflator and the adjustable suction system in response to an amount of smoke sensed.

Abstract
In a surgical system, a system controller executes a video signature identification and image control routine to maintain quality of a video image taken by a video camera located at a surgical site and provided on a video display. The system includes a video camera/light source handpiece for insertion into a patient body. A tool is inserted separately into the surgical site. Fluid input into the surgical site is provided by a liquid pump or by an insufflator. Video signals are analyzed and fluid input/output, fluid pressure, and/or tool operation is automatically controlled to maintain image quality of the surgical site without manual adjustments.

5. A method for controlling a surgical system to provide an acceptable image of a surgical site for display during laparoscopic surgery, comprising:
-
manipulating tissue at the surgical site with a cauterizing tool; providing gas to the surgical site from an insufflator; suctioning the surgical site with an adjustable suction system to controllably remove gas from the surgical site; providing light energy to the surgical site so that the surgical site is viewable; obtaining video image signals at the surgical site with a video sensing device for use in displaying video images on a video display; analyzing the video image signals to determine the presence of smoke that reduces visibility or clarity of the video image signals; configuring a system controller to control the cauterizing tool, the insufflator and the adjustable suction system; in response to sensing a lack of quality and clarity of the video images because of the smoke, controlling at least one of the cauterizing tool, the insufflator and the adjustable suction system with the system controller to provide an acceptable video image quality for viewing without any manual control or manual input from a tool operator; and displaying the video images on the video display. - View Dependent Claims (6)

7. A video based image detection/identification system for fluid and visualization control of an arthroscopic surgical system for providing an acceptable video image of a surgical site, comprising:
-
a cutting tool for manipulating tissue at the surgical site; a liquid pump system for providing fluid to the surgical site; a first adjustable suction system providing suction from the cutting tool through first suction tubing for controlling removal of fluid from the surgical site; a second adjustable suction system providing suction at the surgical site through second suction tubing also for controlling removal of fluid from the surgical site; a light source for providing light to the surgical site; a video sensing device for obtaining video signals of video images at the surgical site; an image display for displaying the video images; and a system controller maintaining quality of video images obtained by the video sensing device and provided to the image display, wherein the system controller receives and processes the video signals to determine a video signature corresponding to a condition that interferes with the quality of the video images, wherein the system controller independently controls a first suction of the first adjustable suction system, a second suction of the second adjustable suction system and an output of the cutting tool between a low cutting level and a high cutting level to address a condition of the fluid at the surgical site to return the video images from the video signals to an acceptable quality for viewing so that a user is free from having to manually control any of the cutting tool, the liquid pump system, the light source, and the video sensing device to obtain the acceptable video image of the surgical site for viewing on the image display. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
