Problems solved by technology

Although the intraocular endoscope 11 has a high degree of freedom in the shooting position, there is a problem that the gravity direction and position of the image are easily lost
Also, if mishandled, the intraocular endoscope 11 may damage the retina 13
[0004] Therefore, the barrier to learning the operation of the intraocular endoscope 11 is very high
In addition, in the current procedure, the guide returns to the original position in case of loss of position, therefore, the operation time will be longer

[0061] (1) Surgical system

[0062] figure 2is a perspective view showing the configuration of a surgical system according to an embodiment of the present technology. figure 2 A basic configuration of a surgical system 100 for ophthalmic surgery is schematically shown. The surgical system 100 includes an operating table 111 , an operating microscope 112 , an image processing device 113 and a presentation unit 114 . In addition, a vitrectomy device, a vital sign display device, and the like may be used as needed, but description thereof is omitted.

[0063] A person to be operated on (ie, a patient) 131 is placed on the operating table 111 . The surgeon 132 stands behind the head 131A of the person to be operated on 131 (or may be left or right), and performs an ophthalmic operation using an ophthalmic operation member. exist figure 2 In the case of the illustrated example, an intraocular endoscope 121 and a surgical tool 122 (eg, a vitrectomy device) are used as surgic...

no. 2 approach

[0100] In the first embodiment, the mark 171 is displayed on the insertion unit 121A of the intraocular endoscope 121 , and the mark 171 is observed, thereby estimating the posture of the intraocular endoscope 121 . In the second embodiment, the posture is estimated from the feature amount from the outside of the intraocular endoscope 121 without adding the marker 171 . In the following, reference will be made to Figure 7 A second embodiment will be described.

[0101] Figure 7 is a diagram for explaining eye surgery according to an embodiment of the present technology. Figure 7 A state in which an insertion unit 121A of an intraocular endoscope 121 is inserted from a trocar 404 into an eye 151 to be operated is shown. A thick handle 401 is attached to a side opposite to the thin insertion unit 121A of the intraocular endoscope 121 via a frustoconical joint 402 . The handle 401 is provided with an edge for preventing slipping, and a cable 403 is connected thereto.

Abstract

The present invention relates to an image processing device and method, an operation system and an operation component, whereby the position or direction of the operation component used for operating an operation object can be determined conveniently. acquiring a microscopic image (201), wherein an image of an operative component (121) inserted into the surgical object is captured by the surgical microscope (112), and based on the acquired microscopic image (201), the relative position of the operative component inside the surgical object is estimated orientation, and output orientation information (222, 223, 224) related to the estimated orientation to the output unit. For example, the present invention can be applied to eye surgery by using an operating microscope to observe an endoscope or surgical instruments.

Description

technical field [0001] The present technology relates to an image processing device and method, a surgical system, and a surgical member, and more particularly, to an image processing device and method by which the position and orientation of an surgical member used in eye surgery can be easily grasped, a surgical A system and an operative component. Background technique [0002] In ophthalmic surgery, an intraocular endoscope is sometimes used when dealing with a position that cannot be visually recognized from a microscope. Intraocular endoscopes are generally used especially for retinal vitreous surgery and the like. [0003] figure 1 It is a diagram for explaining eye surgery. The intraocular endoscope 11 and the surgical tool 12 are inserted into the eye 21 to be operated on. An image 41 of the inside of the operated eye 21 captured by the intraocular endoscope 11 is displayed on the monitor 31 . The surgeon performs surgery while viewing the image 41 on the monito...
