Description

[Detailed Description of the Invention] The present invention relates to a radiation treatment table, and more particularly to a radiation treatment table on which a patient can receive treatment in a sitting position.

Conventionally, when treating a patient in a sitting position on a radiation therapy table such as a rotating cobalt device or a linear accelerator, a general-purpose chair or a dedicated treatment chair has been used. Since general-purpose chairs are not equipped with mechanisms for fixing the patient or positioning the treatment area, they are inconvenient and cannot be expected to provide accurate treatment. For this reason, dedicated treatment chairs are often used.

FIG. 1 is a perspective view of an example of a conventional radiation treatment table.

The chair 1 includes a seat 2, a backrest 3, a head fixture 4,
It consists of an armrest 5, a support 6, and a footrest 7, to which casters 8 are attached to make it movable. This is screwed and fixed to one end of the top plate 10 of the radiation treatment table 9. The patient is seated on this chair, the patient is fixed, and the treatment table is moved vertically and horizontally to position the affected area.

These specialized treatment chairs are free-standing and have a solid structure, so they are extremely heavy, weighing approximately 300 kg. This large weight puts an extra load on the treatment table, and it is also inconvenient to handle.

The purpose of this invention is to eliminate the above-mentioned drawbacks and reduce the load on the treatment table by attaching the backrest, footrest, etc. as attachments separately to the top plate of the radiation treatment table, thereby reducing the individual weights and the overall weight. Another object of the present invention is to provide a radiation therapy table that is easy to handle and allows treatment in a sitting position.

The radiation treatment table of the present invention includes: a backrest that is removably attached to the top plate of the radiation treatment table and has an angle adjustment mechanism; a head fixture that is removably attached to the backrest and has an angle and height adjustment mechanism; The footrest is removably attached to the top plate and has a height adjustment mechanism.

Embodiments of the present invention will be described with reference to the drawings.

FIG. 2 is a side view of one embodiment of the present invention.

A rail 11 is provided on a top plate 10 of a radiation treatment table 9. The backrest 20 has an angle adjustment mechanism consisting of an angle adjustment plate 21 having a sawtooth wave portion and a backrest support member 22, and is removably attached to the rail 11 with a clamp 23. Backrest 20 is arrow 2
Adjustment is possible in the directions indicated by 5 and 26. A belt 24 for fixing the patient is attached to the backrest 20. A support member 32 removably attached to the backrest 20 has a head fixing support column 33 whose height can be adjusted.
is attached, and the head fixture 30 is rotatably and fixably attached to the tip thereof. The head fixing device is provided with a belt 31 for fixing the head. This allows the head fixture to be adjusted in the directions shown by arrows 34 and 35. The footrest 40 is an L-shaped footrest support member 4.
1 with a nut 42 so that the height can be adjusted.
The footrest support member 41 is removably attached to the rail 11 with a pin 43. The footrest 40 can be adjusted in the direction indicated by the arrow 44.

In this way, by dividing each part of the dedicated free-standing treatment chair according to its function and configuring it to be detachable from the top of the treatment table, each part becomes lighter and easier to handle. The load on the moving mechanism can also be reduced.

As explained above, the present invention separates the functions of each part of the free-standing treatment chair and configures it so that it can be directly attached to and detached from the top plate of the radiation treatment table, making it easier to handle and making it easier to handle the horizontal and vertical movement mechanism. It has the effect of reducing the load.
