CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is based on PCT filing PCT/JP2018/031874, filed Aug. 29, 2018, which claims priority to JP 2017-214715, filed Nov. 7, 2017, the entire contents of each are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to a medical display device and a medical observation device.

BACKGROUND ART

In recent years, in a medical field, there are cases where a medical observation device capable of magnifying an observation object such as an affected part are used in order to support microsurgery such as neurosurgical procedure. Examples of the medical observation device include a medical observation device including an optical microscope and a medical observation device including an imaging device functioning as an electronic imaging-type microscope. Hereinafter, the medical observation device including the optical microscope is referred to as an “optical medical observation device”. Hereinafter, the medical observation device including the imaging device is referred to as an “electronic imaging-type medical observation device” or simply a “medical observation device”.

With improvement in image quality of the imaging device and improvement in image quality of the display device on which a captured image is displayed, the electronic imaging-type medical observation device can obtain image quality equal to or higher than that of the optical medical observation device. Furthermore, a user (e.g., medical workers such as operators and assistant operators) using an electronic imaging-type medical observation device does not need to look into the eyepiece constituting the optical microscope as in the case of using an optical medical observation device, and therefore the position of the imaging device can be moved more freely. For this reason, use of the electronic imaging-type medical observation device has an advantage that the operation can be supported more flexibly by the movement of the position of the imaging device, and the use of the electronic imaging-type medical observation device in the medical field has been advanced.

Under such a circumstance, a technology related to a display device used in an operation site has been developed. Examples of the above-described technology include the technology described in Patent Literature 1 below.

DISCLOSURE OF INVENTION

Technical Problem

At the operation site, the display device is arranged, for example, beside the operating table or suspended from the ceiling. On the display device arranged as described above, for example, a captured image that a medical observation device has captured a patient who is to receive medical practice is displayed. An operator such as an operating surgeon or an assistant performs medical practice while viewing the captured image displayed on the display screen of the display device. Hereinafter, a captured image of a patient who is to receive medical practice is referred to as a “captured medical image”. In addition, hereinafter, a display device applicable to a medical field, such as a display device on which a captured medical image can be displayed, is referred to as a “medical display device”.

However, when the operator performs medical practice while viewing the display screen of the medical display device arranged as described above, there occurs “deviation between the actual direction of an affected part of the patient who receives medical practice viewed from the operator and the direction of the display screen on which the captured medical image of the affected part is displayed viewed from the operator”. In addition, even when the display device has a configuration in which the orientation direction of the display device can be adjusted, such as the display device disclosed in Patent Literature 1, a deviation in direction as exemplified above may occur. Then, the deviation in direction as exemplified above may give a great sense of strangeness to a medical doctor or the like who has performed a conventional laparotomy without using any medical observation device. Hereinafter, the deviation in direction as exemplified above is referred to as a “gaze axis difference”.

The present disclosure proposes a novel and improved medical display device and a medical observation device that are capable of improving convenience for medical workers.

Solution to Problem

According to the present disclosure, there is provided a medical display device including: a display device capable of changing a degree of transparency of a display screen; a holding device that holds the display device; and a control device that controls the degree of transparency of the display screen and controls display on the display screen, wherein the display device is held by the holding device so as to be arranged between an operation part of a patient and a medical worker who performs medical practice for the patient.

Moreover, according to the present disclosure, there is provided a medical observation device including: a display device capable of changing a degree of transparency of a display screen; an imaging device that captures a captured medical image; a holding device that holds the display device and the imaging device; and a control device that controls the degree of transparency of the display screen and controls display on the display screen, wherein the display device is held by the holding device so as to be arranged between an operation part of a patient and a medical worker who performs medical practice for the patient, and the imaging device captures a captured medical image in which the operation part of the patient is enlarged.

Advantageous Effects of Invention

According to the present disclosure, convenience for medical workers can be improved.

Note that the above effects are not necessarily restrictive, and any of the effects presented in the present description or other effects that can be understood from the present description may be achieved together with or in place of the above effects.
