Description

3D HIGH DEFINITION IMAGE INTERFACE OF MEDICAL SURGERY MICROSCOPE}

The present invention relates to a three-dimensional high-definition image interface system of the medical surgical microscope, and in detail, by making the two-dimensional image signal of the medical surgical microscope into a three-dimensional high-definition image signal to display, through the three-dimensional high-definition image The present invention relates to a three-dimensional high-definition image interface system of a medical surgical microscope for providing accurate surgical information to surgery and surgical personnel.

In general, a medical surgical microscope is a type of medical device that allows a surgeon to look at the inside of a human body that is invisible or invisible to the doctor's eye in surgery, ophthalmology, neurosurgery, otolaryngology, spinal surgery and obstetrics and gynecology. In addition, the medical surgical microscope is provided with an imaging system that can be viewed through the operation, that is, the monitor of the operation of the operating doctor (hereinafter referred to as "operator").

Therefore, the operator performs the operation while observing the affected part of the patient through a medical surgical microscope, and the assistant and observer and the caregiver related to the patient other than the operator observe the affected part and the surgical progress of the patient in the operating room and outside through the imaging system. I can do it.

However, the imaging system converts an image incident from the medical surgical microscope into an image signal and displays it on a monitor. In this case, the image displayed on the monitor is simply displayed as a two-dimensional image.

Therefore, the operator as well as assistants and observers who assist them have difficulty in accurately observing and confirming the surgical site with the 2D image displayed through the monitor, and the operator cannot perform the operation through the imaging system.

Therefore, the operator has to perform surgery while observing the surgical lesion through the medical surgical microscope. In this case, when the operation is required for a long time, the operator performs the operation while looking through the microscope for a long time, so that the eyes are tired as well as physically. There are many difficult problems that make you feel tired.

In addition, the three-dimensional (three-dimensional) image through the imaging system can not provide accurate progress of the operation of the training practitioners, medical students, or observers are also very poor in understanding and observation.

Therefore, recently, a three-dimensional imaging system capable of performing a surgery while viewing the affected part and the back of the affected part by displaying a surgical procedure as a stereoscopic image has been developed.

In this case, the 3D imaging system captures the same subject as a plurality of images using a plurality of cameras separated into left and right at different positions, acquires, and displays the 3D image using the parallax of the subject included in the plurality of images. It is to realize a three-dimensional image (three-dimensional image).

However, in order to perform the three-dimensional image, a three-dimensional image is generated from a compound eye camera having a plurality of photographing units arranged at predetermined intervals, and a plurality of images acquired by the plurality of image capturing units of the compound eye camera. An interface for displaying an image on a monitor must be implemented.

At this time, the binocular camera is connected to a plurality of eyepieces of the microscope for medical surgery, respectively, to take a plurality of images of the binocular camera to shoot a plurality of images while changing the angle of view and the portion of the image taken through the zoom function to the desired size, The plurality of images photographed by the compound eye camera are converted into a 3D image through an interface and displayed as a 3D image, that is, a 3D image, through a monitor.

However, since the multiple eyepieces are separately connected to the plurality of eyepieces of the medical surgical microscope, respectively, in order to obtain an accurate image at the time of shooting, the zooming operation of the plurality of the cameras of the eyepiece cameras is controlled. Although the photographing part of is changed to a plurality of photographing part angles separated from each other, the case where the focus is not focused between the subject and the lens during the zoom operation.

In addition, the plurality of photographing units of the binocular camera are focused while the plurality of photographing units are synchronized with each other during the zoom operation, but since there are individual differences of the motor and the mechanism for performing the zooming function of the photographing unit, respectively, the zoom operation of each photographing unit is perfectly matched. There is a difficulty.

In addition, when a zooming operation is performed during shooting with a plurality of shooting units of the compound eye camera, the focusing of the plurality of shooting units may be inconsistent with each other, or the angle of view may be different for each shooting unit. I have a problem that does not appear.

An object of the present invention for solving the above problems is to convert the two-dimensional image taken by the compound eye camera to a three-dimensional image to display on the monitor in high quality, to accurately identify the surgical site and the adjacent area through the high-quality three-dimensional image of the monitor It is to make it possible.

Another object of the present invention is to display a high-quality three-dimensional image on the monitor, it is possible to perform the operation while accurately confirming the surgical site as well as the adjacent surgical site through the naked eye.

Still another object of the present invention is to reduce the fatigue of the operator's eyes and body fatigue by allowing the operation to proceed through a monitor displayed in a high-quality three-dimensional image without proceeding through the medical surgical microscope. .

Means of the present invention for solving the above problems is a surgical microscope for expanding the surgical site through the objective lens and the left and right eyepieces, a two-dimensional image enlarged through the left and right eyepieces directly connected to the surgical microscope And a high-quality 3D image interface device for detecting and converting the detected 2D image into a 3D image, and synchronizing and outputting the image in high definition, and a monitor for outputting high quality 3D images output from the high definition 3D image interface device. In the three-dimensional high-definition image interface system of the medical surgical microscope, The high-definition three-dimensional image interface device includes an image sensing unit for sensing a plurality of images from the surgical microscope; An image converter converting an image detected by the image detector into a 3D image; The image conversion unit is characterized in that it comprises a video synchronization unit for synchronizing the 3D image to a high quality image.
