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, a surgical system, and a surgery member, whereby the position or direction of a surgery member for performing surgery on a surgical subject can be conveniently ascertained. A microscope image (201) in which an image of a surgery member (121) inserted in a surgical subject is captured by a surgical microscope (112) is acquired,a relative orientation of the surgery member inside the surgical subject is estimated on the basis of the acquired microscope image (201), and orientation information (222, 223, 224) relating to theestimated orientation is outputted to an output unit. The present invention can be applied to ophthalmic surgery by observing an intraocular endoscope or a surgical instrument through use of a surgical microscope, for example.

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...
