Abstract

To provide a navigation array that can be attached to 3D glasses of a simple type only when needed.SOLUTION: Since a trench part 14 is formed in a spherical marker 13, an array 1 can be attached to 3D glasses 3 only by inserting the trench parts 14 of a plurality of spherical markers 13 into an upper end 12 of a polarization lens 9. Accordingly, the 3D glasses 3 can be used as they are if there is no need for navigation, and the array 1 needs to be attached only when there is need for navigation. This removes the necessity of using an expensive and dedicated 3D glasses to which an array is attached integrally in advance.SELECTED DRAWING: Figure 2

Description

The present invention relates to a navigation array used in the medical field.

Currently, 3D technology that enables stereoscopic observation by viewing a stereoscopic image displayed on a monitor through 3D glasses is adopted in each field. Also in the medical field, images such as CT and MRI or images taken with a surgical microscope are displayed on a monitor, and the doctor observes these images three-dimensionally through 3D glasses.

On the other hand, there is known 3D glasses dedicated to navigation in which an array is integrally attached to 3D glasses used by a doctor. The marker position of the array attached to the dedicated 3D glasses can be detected by the position detecting means for navigation, and the position and orientation of the doctor's head can be recognized. Then, the stereoscopic image displayed on the monitor can be changed according to the position and orientation of the doctor's head. Further, there is an example in which the position of a surgical microscope or the like is moved by a robot arm following the position and orientation of the doctor's head (see, for example, Patent Document 1).

Japanese Patent No. 6513669

However, since 3D glasses used in such medical settings are used not only by doctors but also by assistants for information sharing, a large number of them are used. Therefore, expensive dedicated 3D glasses equipped with an array are disadvantageous in terms of cost.

Therefore, you can use a single-lens polarized lens (the left and right lenses are integrated) and use simple 3D glasses with a pair of left and right temples attached to them, and attach them to the simple 3D glasses only when necessary. A proposal for an array for glasses is awaited.

The present invention has been made in response to such conventional demands, and an object of the present invention is to provide a navigation array that can be attached to simple 3D glasses only when necessary.

According to the first technical aspect of the present invention, it is a navigation array that can be attached to 3D glasses having a single-lens polarized lens having an exposed upper end and a pair of left and right temples, and is attached to the upper end of the polarized lens. It has a plurality of spherical markers formed of an infrared fluorescent resin that has a groove that can be inserted freely and that emits infrared fluorescence as a whole by receiving infrared rays of a specific wavelength, and the plurality of spherical markers each have a groove at the upper end of the polarizing lens. It is characterized in that it is inserted into the lens and lined up in a state where the distance between them is secured.

According to the second technical aspect of the present invention, the groove is formed at a depth reaching at least the center of the spherical marker.

According to the first technical aspect of the present invention, since the groove is formed in the spherical marker, the groove can be attached to 3D glasses as an array simply by inserting the groove of a plurality of spherical markers into the upper end of the polarizing lens and arranging them. .. Therefore, when navigation is not required, the 3D glasses may be used as they are, and the array may be attached only when navigation is required, and it is not necessary to use expensive dedicated 3D glasses to which the array is integrally attached in advance.

According to the second technical aspect of the present invention, since the groove is formed at a depth that reaches at least the center of the spherical marker, the spherical marker can be securely inserted and attached to the upper end of the polarizing lens.

1 to 3 are views showing a preferred embodiment of the present invention.

The array 1 according to this embodiment is used by being attached to the simple 3D glasses 3 worn by the doctor 2. A large monitor 4 is installed in front of the doctor 2. The organ 5 photographed by MRI is displayed on the monitor 4. The display of the organ 5 can be observed three-dimensionally by wearing 3D glasses 3.

A navigation position detecting means 6 is installed on the upper part of the monitor 4, and the position detecting means 6 can detect the array 1 attached to the 3D glasses 3. The position detecting means 6 and the monitor 4 are connected to each other via the controller 8.

The 3D glasses 3 are thin and include a resin-made polarizing lens 9. The polarized lens 9 is a single-lens type with one left and right, and side portions 10 bent at right angles are integrally formed on both left and right sides. Temples 11 for hanging on the ears are attached to the left and right side portions 10. The 3D glasses 3 can be manufactured at low cost with a simple structure including one polarized lens 9 and two temples 11. Since the temple 11 is only attached to the side portion 10, the upper end 12 on the front surface of the polarizing lens 9 is exposed.

Array 1 is composed of three spherical markers 13. The spherical marker 13 is entirely made of an infrared fluorescent resin. The infrared fluorescent resin is obtained by kneading an infrared fluorescent dye that receives infrared rays of a specific wavelength and emits infrared fluorescence into the resin, and has a high emission intensity of infrared fluorescence.

A groove portion 14 having a depth that can be inserted into the upper end 12 of the polarizing lens 9 and reaches the center of the spherical marker 13 is formed on the lower side of each spherical marker 13. The array 1 is formed by inserting and arranging the three spherical markers 13 into the upper end 12 of the polarizing lens 9 in a state where the three spherical markers 13 are respectively secured from each other by using the groove portion 14. Since the groove portion 14 reaches the center of the spherical marker 13, the spherical marker 13 can be securely inserted and attached to the upper end 12 of the polarizing lens 9.

Infrared rays of a specific wavelength are flash-irradiated in the room, and the spherical marker 13 receives the infrared rays and emits infrared fluorescence shifted by a predetermined wavelength from the infrared rays. The position detecting means 6 detects only the infrared fluorescence of the wavelength emitted from the spherical marker 13, and does not detect the other infrared rays.

The position detecting means 6 detects the infrared fluorescence of the spherical marker 13, and the position information is output to the controller 8, so that the controller 8 can recognize the position and inclination of the head 7 of the doctor 2. Then, the orientation of the organ 5 displayed on the monitor 4 can be changed in conjunction with the recognized head 7. For example, if the head 7 of the doctor 2 moves to the right, the organ 5 in the monitor 4 can also rotate to see the right side surface of the organ 5.

According to this embodiment, the array 1 can be attached to the 3D glasses 3 simply by inserting the groove 17 of the spherical marker 13 into the upper end 12 of the polarizing lens 9, so that the organ 5 remains as it is without the need for navigation. If you want to observe in the state of, you can use the 3D glasses 3 as it is, and if you want to change the direction of the organ 5 by using the navigation, you can attach the array 1. Since it is not necessary to use expensive dedicated 3D glasses, it is advantageous in terms of cost.

Further, since the array 1 is removable from the 3D glasses 3, it is easy to store and sterilize when not in use.

In the above embodiment, a structure is shown in which a pair of left and right temples 11 are attached to the side portions 10 of the polarizing lens 9, but the front side of the left and right temples wraps around to the front surface of the polarizing lens 9 and is connected. It may be a structure. Even in such a case, since the upper end 12 of the polarizing lens 9 is exposed above the connecting portion of the temple, the array 1 can be attached to the upper end 12.
