Description

Frame for fixing whole body in regular position for radiotherapy

The present invention relates to a frame for systemic stereotactic radiotherapy that maintains and fixes a patient's position or posture with respect to radiation equipment when treating or diagnosing a patient with medical radiation equipment.

Radiation for medical use can be divided into therapeutic radiation and diagnostic radiation.

Therapeutic radiation is applied to cancer patients' tumors to prevent them from propagating anymore so that the cancer cells die at the end of their life or to alleviate the patient's pain.

Such radiation therapy can be used to prevent recurrence, for example, in cases where cancer cells are more likely to remain after surgery, or when surgery is not possible, or when radiation therapy is more effective than surgery, or a combination of surgery and radiation therapy In order to improve the quality of life of the patient, or to maximize the anticancer effect after chemotherapy.

On the other hand, the diagnostic radiation is used to determine the size or location of the tumor in the patient's body, and helps to analyze the contents of the patient's area of interest with radiation of weaker energy than the therapeutic radiation, and to analyze the contents and establish a detailed treatment plan.

On the other hand, radiation therapy with linear accelerators usually lasts two to six weeks, depending on the condition of the tumor. In most cases the size of the tumor is reduced to some extent during the treatment and the weight of the patient is usually reduced by about 5 kg to 10 kg. As a result of this change in weight or tumor size, the tumor size should be taken at least once a week to re-establish the appropriate radiation energy intensity and irradiation area corresponding to the remaining tumor size. In order to increase the rate of cancer cure through radiotherapy, the area must be continuously photographed to observe the change in tumor size or condition and to take necessary measures at that time.

As described above, since the radiation treatment is not completed at one time but several times, the radiation of the correct energy should be irradiated at the correct position so that the normal part around the tumor is not exposed to the radiation. To this end, treatment planning to prescribe accurate radiation by identifying the size or location of the tumor in advance is preceded.

The treatment plan also includes marking the site of radiation on the patient's body. This display process is based on the image taken by an imaging device such as CT or MRI or X-rays.

After completing the treatment plan, the patient is placed on the treatment table of the linear accelerator, and radiation is irradiated to the corresponding tumor site to perform the actual treatment. At this time, it is a matter of course that the mark displayed on the patient's body is used as a reference for the irradiation direction.

On the other hand, since the radiation treatment is usually performed several times as described above, there is a need for a support for positioning the patient more quickly and accurately in the same position as the first treatment position. A support for this purpose is a frame for systemic radiotherapy. The frame for systemic stereotactic radiotherapy helps the patient to be more comfortable in the first treatment position so that the patient can receive the treatment accurately and conveniently.

However, the conventional frame for generalized stereotactic radiotherapy can not stably fix the patient's body when the target area is the lung or liver area that can only be moved by the patient's breathing. There was a problem that it was difficult to irradiate accurate radiation.

The present invention has been created to solve the above problems, it is possible to more stably fix the patient to be treated on the treatment table of the radiation equipment for the purpose of treatment or diagnosis, three-dimensional stereotactic radiotherapy or three-dimensional stereoscopic radiotherapy or intensity An object of the present invention is to provide a frame for systemic stereotactic radiotherapy that enables precisely controlled radiotherapy (IMRT).

1 is a partially exploded perspective view of a frame for systemic stereotactic radiation treatment according to an embodiment of the present invention.

Referring to the drawings, the frame 11 for systemic stereotactic radiation treatment according to the present embodiment, the main plate 13 of the rectangular shape that the patient can lie on it, and both sides of the upper surface of the main plate 13 Two support frames 19 fixed to the support frame 19 and the support frame 19 on both sides and the belt 27 is fastened to each other and fastened to the patient, the becum cushion located between the support frame 19 ( 63 and FIG. 3, and a light irradiation part 49 positioned on the support frame 19.

The main plate 13 is a rectangular plate having a predetermined thickness and is provided with a ruler 14 on both sides of the thickness surface. The ruler 14 serves to measure the position of the light irradiation unit 49 with respect to the main plate 13. In addition, the ruler 14 may be formed by engraving the scale directly on the thickness of the main plate 13, or may be fixed to install a separate ruler is engraved scale.

Known localizers 17 and 18 are provided at the center of the upper surface of the main plate 13. The localizers 17 and 18 are made of a material which radiation cannot pass through and have a plurality of interconnected N-type patterns. The localizers 17 and 18 may be made of copper or lead, or may be manufactured by coating lead on a thinly drawn high density synthetic resin.

The localizers 17 and 18 may be formed by forming a groove having the pattern on the upper surface of the main plate 13 and partially or completely inserting the groove into the inside of the main plate 13. It can also be attached on top of it.

The localizers 17 and 18 allow the position of the image obtained by tomography of the patient's body or head lying in the main plate 13 in the longitudinal direction. Since the functions of the localizers 17 and 18 are well known general techniques, description thereof will be omitted.

On both sides of the localizer 17, a plurality of female threaded spheres 15a and 15b are formed in a row. The female screw sphere 15a, 15b is a hole in which the female thread is formed on the inner circumferential surface thereof and engages with the coupling bolt 25 passing downward through the support frame 19. As for the female screw holes 15a and 15b, eight inner female screw balls 15b and outer female screw balls 15a are located at equal intervals.

Thus, by forming the female screw sphere (15a, 15b) in two rows on the inside and the outside it is possible to adjust the spacing of the support frame 19 fixed on the main plate 13 relatively narrow or wide.

The support frame 19 is fixed on the main plate 13 through the coupling bolt 25. To this end, four through holes 23 are formed in each support frame 19. The position of the through hole 23 corresponds to the positions of the female screw holes 15a and 15b, of course. Therefore, when the support frame 19 corresponds to the female threaded spheres 15a and 15b of the outer row or the inner row and the engaging bolt 25 is coupled to the female threaded sphere, the support frame 19 is coupled to the main plate 13. This is done. The support frame 19 may be made of synthetic resin or acetal.

Each of the optical pointers 55 irradiates light on the patient's body so that the operator can check the irradiation surface and display its position.

In the present embodiment, since the three light pointers 55 are provided, the three light pointers 55 may be displayed at three places by irradiating light on the sides and the chest of the patient lying on the main plate 13, for example.

Figure 2 is a perspective view showing the assembly of the frame for the systemic stereotactic radiation treatment of FIG.

The same reference numerals as the above reference numerals denote the same members having the same function.

As shown in the drawing, the support frame 19 is spaced apart as far as possible from the upper surface of the main frame 13. The support frame 19 is coupled to the outer female threaded ball (15a in Figure 1). In addition, three belts 27 are provided between the support frames 19 on both sides. The belt 27 is composed of a fixing belt 73 and the fastening belt 74 and can be fixed by tightening the patient by pulling the front end portion of the fastening belt 74 in the arrow a direction.

The light irradiation part 49 is positioned above the main plate 13. As described above, the lower ends of the vertical frames 67 on both sides of the light irradiation unit 49 cover the ruler (14 in FIG. 1) of the main plate 13. Therefore, the position of the light irradiation part 49 with respect to the main plate 13 is checked by the ruler (14 of FIG. 1) seen through the vertical frame 67. As shown in FIG.

Figure 3 is a perspective view showing the overall configuration of the frame for systemic stereotactic radiation treatment according to an embodiment of the present invention.

Referring to the drawings, it can be seen that the known becum cushion 63 is further installed between the support frame 19. The becum cushion (63) is the upper part of the becum cushion (63) when the patient withdraws the air in the state lying down, partially wraps the patient's body and forms a mold corresponding to the patient's body shape to finally secure the patient's body Let's do it.

In addition, the becum cushion 63, once formed a mold corresponding to the body shape of the patient continues to maintain its shape unless the air is injected again. Therefore, once used becum cushion (63) is stored as it is to be installed again to take out the next radiotherapy or imaging to allow the patient to lie in the interior space of the becum cushion (63) quickly and easily position the patient.

4 is a view illustrating an example of use of a frame for systemic stereotactic radiation treatment according to an embodiment of the present invention.

As shown, the patient is lying on the main plate 13 and the becum cushion 63 is located between the main plate 13 and the patient.

It can also be seen that the three belts 27 tighten the chest and abdomen of the patient. When fastening the patient with each belt 27, the degree of tightening is checked and memorized by the ruler 29 provided in the belt 27. By remembering the degree of tightening as described above can be measured to the same degree during the next radiation treatment, and it can be seen that the tightening length is changed when the weight of the patient is reduced.

In addition, the belt holder 33 supporting the belt 27 is fixed to the corresponding portion of the support groove 21 by the stopping bolt 43.

On the other hand, it can be seen that the light irradiation unit 49 covers both sides and the front of the patient. As described above, the position of the arrow x direction of the light irradiation unit 49 may be precisely adjusted through the ruler 14, so that the light irradiation unit 49 may be set back to the position where the first radiation treatment was placed.

In addition, the sliding block 51 installed on the vertical frame 67 of the light irradiation unit 49 can be elevated in the arrow y direction. At this time, the measuring hole 69 formed in the sliding block 51 can determine how high the position of the sliding block 51 is at present.

Similarly, through the measurement hole 69 formed in the sliding block 51 of the horizontal frame 65, it is possible to know in which position of the horizontal frame 65 the sliding block 51 is currently located. As described above, after grasping and remembering the positions of the respective sliding blocks 51 through the ruler 47, the sliding blocks 51 may be positioned at the position when the first treatment is performed once.

In addition, the sliding block 51 is provided with an optical pointer 55 for irradiating light toward the patient's body. Since the light irradiated from the optical pointer 55 appears in the form of a dot on the patient's body, the display portion M may be marked to confirm that the irradiation portion is irradiated on the irradiated portion of the light irradiated by the optical pointer 55. In this way, the patient's next treatment is set to the same equipment as the first treatment and the light pointer 55 is irradiated with light so that the indicator M is aligned with the light of the light pointer 55. Allows the same posture to be taken in the same position as the first treatment.

If the patient is fixed in the correct position through the above process, the light irradiation unit 49 is removed and full-scale treatment or imaging is started.
