DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote surgery support system in which a surgeon in an operating room can perform a surgery in response to an instruction from a remote supporter.

[0002]

2. Description of the Related Art Endoscopes are widely used in the medical and industrial fields. Recently, an endoscope with a television camera externally mounted with a television camera equipped with imaging means at the eyepiece of an optical endoscope, or an electronic endoscope with built-in imaging means at the distal end has been used. 2. Description of the Related Art An endoscope apparatus that displays a captured endoscope image on a monitor and performs observation and treatment while viewing the image is widely used.

The endoscope apparatus includes a light source device for supplying illumination light to the endoscope, a camera control unit (also referred to as a video processor) having an image signal processing circuit for displaying an endoscope image, and an endoscope. In addition to a TV monitor for displaying a mirror image, an endoscope system capable of performing treatment or surgery under endoscopic observation has been constructed using a plurality of peripheral devices, for example, an insufflation device, a high-frequency cautery device, and the like. Has been

In this endoscope system, these plural peripheral devices are usually connected to a system controller for centralized control.

In the above-mentioned transendoscopic operation, even a physician with little experience can ensure that an experienced physician observes an endoscopic image displayed on a monitor and receives instructions. Surgery can be performed. At this time, when the endoscopic image of the operative field to be displayed on the monitor is important and the displayed endoscope image is different from the endoscope image indicating the operative field desired by an experienced doctor, Surgery could be performed smoothly jointly by giving verbal or direct instructions to the surgeon.

[0006] For this reason, for example, in the case where an experienced doctor who gives instructions is in a remote place, for example, in a hospital where a doctor who is a supporter who is in a remote place is located, and an operating room where a doctor in charge of surgery is provided, the operation room is provided. Are connected by a public line, and a system that supports a physician in an operating room to perform an appropriate operation on a patient while receiving instructions from a physician at a remote place during the operation has been considered.

[0007] As a remote operation support system for remotely supporting an operation, the present applicant has filed Japanese Patent Application No.
No. 318019 proposes a remote surgery support system. In this prior art, when performing an operation for controlling the operation of a surgical instrument via a manipulator, an operation signal for controlling the surgical instrument by a remote support operator is made to be understood by the operator in the operating room. In this way, they can work together smoothly.

[0008]

However, in the above prior art, an endoscope image of a necessary surgical field cannot always be displayed on a monitor in transendoscopic surgery. Cannot accurately grasp the condition and position of the affected part.

Further, even if the endoscope image can be displayed on a monitor by any means, only a doctor at a remote place can observe the endoscopic image of the operation field which is important in transendoscopic surgery. The endoscope image displayed on the monitor cannot be adjusted or changed to a desired state by hand operation in the same manner as in an operating room.

The present invention has been made in view of the above circumstances, and not only allows a doctor at a remote place to observe an endoscope image via a communication line, but also displays an endoscope image displayed on a monitor. To the desired state by hand operation,
It is an object of the present invention to provide a remote surgery support system that can provide appropriate support to an operator in an operating room.
