Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a head-mounted image display device which is used in a medical field such as endoscopic surgery and is mounted on the head by an operator such as a doctor.

[0002]

2. Description of the Related Art A head-mounted image display device (hereinafter referred to as HMD
Is a device in which a device such as a goggle type or spectacles type is mounted on the head, and images and sounds sent from an external device via a cable are viewed. Young people are attracting attention, as they can enjoy stereoscopic images and stereo sound both indoors and outdoors. On the other hand, HMD
Is also attracting attention in the medical field. this is,
The purpose of the present invention is to obtain information that cannot be observed with the naked eye by allowing a doctor or the like to view information relating to a patient's surgery or treatment site as a video in a medical field such as a surgical operation. at the same time,
There are also cases where naked eye observation, so-called see-through observation is performed by switching the device, or the device is opened from the front of the eye. The present invention is an HMD used in such medical fields.
Regarding

[0003]

By the way, during use of the HMD, the surface of the image display member may become cloudy depending on the breath of the user, ambient temperature and humidity conditions. This means that the operator cannot directly touch the HMD to deal with the cloudy condition or to open the device from the front of the eye at the medical site, especially during surgery. It was a big unsolved problem. In other words, the operator's hand must be kept in a sufficiently sterilized state,
It is not possible to release the cloudy state by touching the HMD that has not been sterilized. In this regard, a conventional example has been proposed in which a transparent heater for heating an optical means is provided (Japanese Utility Model Laid-Open No. 5-79526), but this can prevent fogging, but the operator does not directly apply to the HMD. The problem that the device cannot be operated by touching the crab is still unsolved.

In addition, the fact that the operator cannot touch the HMD means that the operator cannot wipe the sweat even if he sweats during the surgical operation. It means that it is not possible to adjust the device. Therefore, when these are necessary, the hands of the nurses and the like will have to be confused. In other words, the surgeon can attach, adjust, and
The inconvenient state cannot be released or removed. In this regard, liquid crystal television devices are disclosed in Japanese Patent Laid-Open Nos. 63-294186 and 4-23582.
A content is disclosed in which a user can freely attach and adjust the image display device by hand. However, these conventional examples do not assume a sterilized hand, but allow the user to attach and adjust the liquid crystal television device and the image display device with the hand in a normal state.

The present invention has been proposed in order to solve the above-mentioned problems, and an object thereof is to provide an HMD that can be attached and detached by a surgeon such as a doctor with his / her own hand.

[0006]

In order to achieve the above-mentioned object, the present invention provides a head-mounted image display device comprising a head fixing part to be mounted on the head and a display part having an image display member, This head-mounted image display device is configured to have a detachable and sterilizable grip member.

[0007]

The head-mounted image display device is mounted, adjusted, and removed by the user himself by mounting a sterilized gripping member on the display unit.
