Description

  The present invention relates to a jig for supporting a female breast in medical use, and more particularly to a jig for supporting a female breast during imaging of a nuclear medicine examination.

  Breast cancer is prone to metastasis to nearby lymph nodes such as the axilla, sternum, and clavicle in the vicinity of the breast, and should be detected early.

  Diagnosis of breast cancer is performed using medical equipment such as a nuclear medicine diagnostic apparatus, mammography, ultrasonic diagnostic apparatus, MRI apparatus, and X-ray CT apparatus. In particular, the nuclear medicine diagnostic apparatus is one of the most suitable apparatuses for diagnosing breast cancer because of the high resolution of diagnostic images and the ability to simultaneously diagnose not only the breast but also the above-mentioned lymph nodes.

  The nuclear medicine diagnostic apparatus detects radiation derived from a radionuclide administered to a subject by a detector arranged around the bed. As a nuclear medicine diagnostic apparatus, a positron emission computed tomography (hereinafter referred to as “PET apparatus”) or a single photon emission tomographic apparatus (hereinafter referred to as “SPECT apparatus”). Representative.

  The PET device labels a radionuclide that emits positrons by nuclear decay and administers it into the body, and when a pair of positrons and electrons annihilate in the body, a pair of γ rays are emitted in the direction of 180 ± 0.6 °. This is a nuclear medicine diagnostic apparatus that detects (511 keV) and reconstructs a tomographic image of a subject.

The PET examination has advantages such as high resolution of diagnostic images and relatively small exposure amount of the subject. Radionuclides used for PET examination are mainly ¹⁸ F, ¹⁵ O, ¹³ N, ¹¹ C, etc., and each radionuclide is, for example, ¹⁸ F-fluorodeoxyglucose (analogue of glucose). FDG), ¹⁵ O—CO, ¹³ N—NH ₃ , ¹¹ C and the like can be administered to a subject as a radiopharmaceutical such as a neurotransmitter labeled. In particular, FDG is used to identify a tumor site by utilizing its high accumulation in tumor tissue by sugar metabolism.

  The PET apparatus includes an imaging apparatus, a data processing apparatus that processes detection data obtained by imaging by the imaging apparatus and converts the data into image data, and image data output by the data processing apparatus in two dimensions or three dimensions. A display device for displaying and a bed that supports the subject and is movable in the body axis direction of the subject.

  In a general whole-body PET examination, the subject is imaged by inserting a bed on which the subject is kept in a supine position into a hole formed in the imaging device. In such an imaging method, for example, when imaging a specific tissue such as a woman's breast, there is a problem that the shape changes due to a slight difference in posture, or the volume changes due to gravity. Arise. As a result, the detection sensitivity of the tumor is lowered, or even if it can be detected, the accurate position cannot be specified.

Therefore, an apparatus for fixing a female breast for various medical uses is disclosed (for example, see Patent Document 1). The female breast fixing device disclosed in Patent Document 1 includes a container fixing membrane in which the chest is accommodated and at least one cushion that presses the chest against the fixing membrane. When imaging a female breast using such a device, the subject is in a prone position on the bed on which the chest housing portion is formed, and the breast is housed in the chest housing portion while housing the breast in the chest housing portion. By fixing with an installed cushion, the shape and volume can be fixed and imaging can be performed.
JP 11-192221 A

However, in order to fix the lower part and the side part of the breast with a cushion, the apparatus disclosed in Patent Document 1 must capture an image in a state where the breast shape of the fixed surface is compressed, and thus has a natural shape and volume. There was a problem that the image could not be taken. In Patent Document 1, since this apparatus is assumed to be applied mainly to ultrasonic diagnosis, the influence of the problem of breast compression is not particularly considered, but a tumor is detected using FDG. In the PET examination, there is a problem that FDG is likely to accumulate in a site to be pressed, and that there is a problem in proper discovery of the tumor.
Further, in Patent Document 1, there is one breast accommodating portion, and in order to image both breasts, the other one has to be imaged after imaging one.
Furthermore, since it takes a burden on the subject's head, chest, hips, knees, toes, etc. for the subject to be prone for a long time during the examination, a device configuration that supports only the vicinity of the chest is sufficient. I can't say that.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a female breast support jig capable of maintaining a shape and volume in a natural state without particularly compressing a breast in medical use.

In order to solve the above-mentioned problems, the present invention provides a head support unit that supports the head of a subject or a patient who is in a prone position, and an abdomen support unit that supports the abdomen of the subject or the patient. A chest support part that connects the head support part and the abdominal support part and supports the sternum part of the subject or the patient , the head support part, the abdominal support part, and the chest support part An accommodating portion formed in such a manner as to accommodate the breast of the subject or the patient suspended from the opening and hermetically sealed at the time of accommodation ; When the subject or the patient's breast is housed in the housing, suction means for sucking out the breast without contacting the breast by discharging and decompressing the air in the housing; the equipped and wherein the Rukoto.

  According to the present invention, in medical use, the shape and volume can be maintained in a natural state without particularly compressing the breast. In particular, since the support jig for female breasts does not compress the breast, the use of the support jig for nuclear medicine diagnosis prevents radiopharmaceuticals from collecting in the breast compression area, and diagnosis of breast cancer through nuclear medicine diagnosis. Accuracy can be improved.

  Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings as appropriate. In the present embodiment, a PET apparatus will be described as an example of a nuclear medicine diagnosis apparatus to be applied. However, the present invention is not limited to a PET apparatus, but can be applied to other nuclear medicine diagnosis apparatuses such as a SPECT apparatus. It is shown. Furthermore, the present invention can also be applied to other medical devices.

  In the drawings to be referred to, coordinate systems having orthogonal coordinate axes X, Y, and Z are appropriately added to clearly indicate directions. The coordinate axis Z is the longitudinal direction of the bed, and is the body axis direction of the subject who is prone on the bed. Also, the coordinate axis X is a short direction of the bed, and the coordinate axis Y is a direction perpendicular to the surface of the bed.

  As shown in FIG. 1, a female breast support jig (hereinafter simply referred to as a support jig) 1 that is also a female breast imaging aid is mainly composed of a head support part 2, a chest support part 3, and an abdomen support part. 4 and the leg support part 5, and these are comprised integrally. The chest support part 3 is disposed between the head support part 2 and the abdomen support part 4 and connects them. The leg support 5 is coupled to the abdomen support 4 on the opposite side of the chest support 3. The support jig 1 is used by being placed on the bed B of the PET apparatus. A pair of accommodating portions S surrounded by the respective side surfaces of the head support portion 2, the chest support portion 3 and the abdominal support portion 4 are formed on both sides of the chest support portion 3. Each breast of the subject H is drooped into each housing part S and is housed in a natural shape and volume.

  If a step occurs at the boundary between the support portions 2 to 5, when the subject H becomes prone on the support jig 1, the posture of the subject H becomes unstable, or the subject In order to give local compression to H, the height of the upper surfaces of the support portions 2 to 5 is continuously and smoothly formed. In particular, the upper surfaces of the support portions 2 to 4 are preferably formed at a certain height.

As shown to Fig.2 (a), the support parts 2-5 have the 2 layer structure which distribute | arranged the upper layer parts 2b-5b on the upper part of the base parts 2a-5a, respectively.
The materials of the base portions 2a to 5a are rigid enough not to be deformed by the load of the subject H, and further, γ rays emitted from the subject H are circulated around the hole portion 50 in the imaging device 101 (FIG. 8). It is comprised by the material which permeate | transmits without attenuating to the radiation detector (arranged around the test subject H) arrange | positioned in (3). For example, the material of the bases 2a to 5a is preferably a resin or plastic having a low specific gravity, and more preferably a foam of a resin such as polystyrene foam or urethane foam. Moreover, you may use the other raw material which is easy to permeate | transmit a gamma ray for base 2a-5a. Moreover, the structure which filled the fillers, such as gel and air, into the outer bag may be sufficient like the pillow and bed currently used.

The bases 2 a to 4 a have a height that ensures that the breast of the subject H housed in the housing part S does not touch the bed B exposed below the support jig 1.
The lower limit of the base height L required for the bases 2a to 4a is defined with an allowance of several centimeters, for example, on the average breast height from the front breast to the papilla of a woman's drooped breast. In addition, if the base height L is excessively high, the posture of the subject H who is in the prone position on the support jig 1 of the female chest becomes unstable, so the upper limit of the base height L is also appropriately set. It is prescribed.

  The upper layer portions 2b to 5b are made of a member having flexibility, and remove physical fatigue and local compression caused by the subject H lying on the support jig 1 in the prone position. The material of the upper layer portions 2b to 5b can be composed of, for example, a sponge or a nonwoven fabric. Moreover, you may comprise the upper layer parts 2b-5b by an outer bag and a filler, respectively, so that the soft touch which a subject H may touch with an outer bag may improve a softness | flexibility with a filler, respectively.

A width M of the female breast support jig 1 shown in FIG. 2B is formed wider than the body width of the subject H in order to stabilize the posture of the subject H in the prone position. The On the other hand, in order to use it mounted on the bed B, it is formed with a width narrower than the width of the bed B.
Hereinafter, each support part 2-5 is demonstrated in detail.

(Head support)
The head support unit 2 supports a range from the upper chest part of the subject H to the head. Here, the “upper chest” is the chest above the breast (in the head direction) and does not include the breast region. For example, it refers to a position 3 to 5 cm above the upper part of the outer edge of the breast of the subject H, or above a position corresponding to the clavicle of the subject H. As described above, since the breast portion is not compressed by the head support unit 2, the FDG is not accumulated by the compression, and the influence on the diagnostic image (tomographic image) of the breast imaged by the PET apparatus can be reduced. it can.
Here, the subject H who examines the chest with the nuclear medicine diagnostic apparatus includes patients who have already developed a tumor such as breast cancer and have a history of treatment with radiation. When radiotherapy is performed for breast cancer, the ribs and clavicles are often fragile as compared to healthy individuals due to the irradiation of breast cancer and lymph nodes.
Therefore, the head support unit 2 of the present embodiment is configured to support the neck and head as appropriate in order to disperse the load applied to the clavicle when the subject H is in the prone position. . In addition, when the subject H grasps and captures a grip portion (see FIG. 3) 6 to be described later, both arms of the subject H can be supported by the head support portion 2.

As shown in FIG. 3A, a recess 21 is formed in a region of the head support 2 corresponding to the face of the subject H. The head support part 2 can fix the head by inserting the head of the subject H into the recess 21.
As shown in FIG. 3 (b), the concave portion 21 is compared with the face support surface 21a formed along the shape of the peripheral portion of the face such as the forehead, cheekbone, and chin of the subject H, and the shape of the face. The center deep portion 21b is formed one step deeper. The face support surface 21 a is a surface that substantially supports the face of the subject H in the recess 21. On the other hand, by providing the central deep portion 21b, the eyes, nose, mouth and the like of the subject H do not come into contact with the head support portion 2, and the subject H can be prevented from feeling uncomfortable.

  Thus, by providing the recessed part 21 in the head support part 2, the surface area which supports the subject H can be enlarged and the load concerning the rib and clavicle of the subject H can be distributed. Moreover, since the recessed part 21 is formed along the shape of the head, the subject H can always be fixed at the same place.

  Further, as shown in FIG. 3B, a grip portion 6 for gripping the subject H is provided at the end in the Z-axis direction of the head support portion 2. The grip portion 6 includes a shaft rod 6a fixed to the base portion 2a of the head support portion 2 and a grip rod 6b fixed orthogonally to the shaft rod 6a, and each is made of, for example, plastic. When the subject grasps the grasping rod 6b of the grasping portion 6, the posture of the subject H in the prone position on the support jig of the female chest can be stabilized.

(Chest support)
As shown in FIG. 2, the chest support portion 3 supports a portion between the breasts of the subject H, that is, a portion corresponding to the sternum (sternum portion). The chest support unit 3 is arranged so as to connect the head support unit 2 and the abdomen support unit 4 along the center line of the subject H. Since the support jig 1 includes the chest support 3, the load on the subject's clavicle can be dispersed.
The width (thickness in the X-axis direction) of the chest support part 3 is preferably as wide as possible without touching the subject's breast. By widening the width of the chest support part 3, not only the clavicle of the subject H but also the load on the sternum can be reduced. Moreover, since the breast part is not compressed by the chest support part 3, the influence on the diagnostic image of the breast imaged by the PET apparatus can be reduced.

[Abdominal support part]
The abdomen support unit 4 supports the abdomen of the subject H. For example, the upper limit is set with reference to a position 5 to 7 cm below the lower end of the outer edge of the breast of the subject H or a position corresponding to the lower sternum of the subject H. The abdomen support part 4 is in continuous contact with the leg support part 5 in a region corresponding to the waist of the subject H.

Further, as shown in FIG. 2B, the abdomen support part 4 has a connection length N (interval between the head support part 2 and the abdomen support part 4) for adjusting the chest support part 3. Chest support length adjusting means 10 is provided. For example, the chest support portion length adjusting means 10 is configured such that an end 3c of the chest support portion 3 is slidably inserted into an elongated groove 4c formed in the abdominal support portion 4. The groove 4 c is located on the accommodating part S side of the abdominal part support part 4. Although not shown, a scale may be provided along the Z-axis direction of the groove 4c in order to record the adjusted connection length N of the chest support 3. Further, a fixing means for fixing the adjusted connection length N of the chest support 3 may be provided on the abdomen support 4 so as not to hit the subject H. As this fixing means, for example, a conventional fixing tool such as a screw or a stopper can be used.
Thus, by providing the abdominal support part 4 with the chest support part length adjusting means 10, the connection length N of the chest support part 3 can be adjusted according to the physique of the subject H.

(Leg support)
The leg support 5 supports the leg of the subject H. For example, the leg support 5 supports the subject's thigh, that is, from the lower waist to the upper knee. The leg support 5 itself is not directly related to the support of the female breast, but by providing the leg support 5, the waist when the subject H becomes prone on the support jig 1 of the female breast. Can be reduced. Specifically, the onset of the back pain of the subject H can be prevented by installing the leg support 5. In addition, the reason why the lower limit of the leg support 5 corresponds to the portion corresponding to the upper part of the knee is that the subject H places the knee and toes on the bed B in the bed width direction (Y-axis direction). The balance can be adjusted by one's own power, and a sense of security can be brought to the subject H. Further, since the height of the leg of the subject H is lower than the head, the center of gravity of the subject H is shifted in the leg direction, and the subject H is in the prone position. Can be kept stable.

  In addition, it is set as the structure open | released on the opposite side to the chest support part 3 of each accommodating part S dare. This is to solve the following two problems. That is, when a side support part for supporting a body side part such as an axilla of the subject H is provided on the side opposite to the chest support part 3 of the housing part S, the side support part is in a prone position. This is because the examiner's H breast is pressed from the side.

<How to use female breast support jig>
Hereinafter, a method for diagnosing a female breast using a PET apparatus to which the support jig 1 is applied will be described.
First, the structure of the PET apparatus 100 to which the support jig 1 is applied will be described with reference to FIG. The PET device 100 includes an imaging device 101 in which a hole 50 is formed, a data processing device 102, a display device 103, and a bed B. The imaging device 101 has a plurality of radiation detectors (not shown) arranged so as to surround the hole 50. The bed B holds the subject H and can move in the longitudinal direction. This bed B is inserted into the hole 50. The radiation detector detects γ-rays generated from the subject H on the bed B due to the radiopharmaceutical. The data processing device 102 receives output data output from a signal processing device that processes a detection signal from the radiation detector. The data processing apparatus 102 further generates a tomographic image (PET image) that is a functional image based on the output data. This tomographic image is displayed on the display device 103.

In advance, the subject H is administered with a radiopharmaceutical, for example, fluorodeoxyglucose (FDG) containing ¹⁸ F of half-life of 110/110. This radiopharmaceutical accumulates, for example, in the lesions of breast cancer and metastases.
First, the subject H is in the prone position on the support jig 1 placed on the bed B of the PET apparatus 100, and the chest support part length adjusting means 10 is used according to the physique of the subject H. The connection length N of the chest support 3 is adjusted. Next, the subject H places the head on the head support 2, the sternum on the chest support 3, the abdomen on the abdomen support 4, and the thigh on the leg support 5, respectively. The breast is drooped into each housing part S. In addition, the subject H can stably maintain the prone posture by grasping the gripping rod 6b of the gripping portion 6.

  Then, the bed B is adjusted to a predetermined height and is inserted into a hole 50 (see FIG. 4) formed in the imaging device 101. Here, the predetermined height of the bed B is determined so that the body axis of the subject is positioned substantially at the center of the hole 50 of the imaging device 101 in a general PET examination. However, when the support jig 1 is placed on the bed B, the height of the bed B is such that the center O of the subject's trunk is positioned at the center of the hole 50 (see FIG. 4). Adjusted. Therefore, it can be said that such a height of the bed B is appropriate for imaging of the breast by the PET apparatus 100 using the support jig 1.

  Then, the subject H is imaged by the imaging device 101 of the PET apparatus 100. According to the imaging by the PET apparatus 100, it is possible to image the area indicated by the solid diagonal lines in FIGS. That is, simultaneously with imaging of a tumor in the breast, imaging of a lesion metastasized to a regional lymph node can be performed. Specifically, the above-described γ rays resulting from the radiopharmaceutical accumulated in the cancer are detected by the radiation detector of the imaging apparatus 101. A tomographic image is created based on the output signal of the radiation detector. Note that when a breast is diagnosed with a medical diagnostic device different from the nuclear medicine diagnostic apparatus, only a portion of the breast described in a stitch shape can be imaged. Therefore, among various medical devices, in particular, the support jig 1 applied to the imaging by the nuclear medicine diagnostic apparatus draws out the advantages of the nuclear medicine diagnostic apparatus more than before, so that breast cancer, regional lymph nodes, and metastatic lesions can be obtained. Can contribute to discovery.

According to the above, the following effects can be obtained in the present embodiment.
By configuring the head support unit 2, the chest support unit 3 and the abdomen support unit 4 to be loaded on the ribs and collarbones when the subject H is in the prone position on the support jig 1. Can be dispersed. In particular, since the sternum portion of the chest of the subject H is supported by the chest support portion 3, the load on the ribs and collarbone supported by the head support portion 2 when the prone position is achieved (the weight of the chest). Can be reduced. As described above, the subject H who has already undergone radiotherapy for breast cancer often has brittle ribs and clavicles as compared to healthy individuals. For this reason, supporting the sternum portion by the chest support portion 3 can reduce the load on the ribs and clavicles at the time of the PET examination, and can avoid fractures of the ribs and clavicles. In addition, by providing the chest support portion 3 that supports the sternum, the support jig 1 can be configured to open the side opposite to the chest support portion 3 of each housing portion S, so that it is in a prone position. A side support portion that supports the side portion of the body such as the armpit of the subject H is not necessary.
The support jig 1 can cause each breast of the subject H to hang down in a natural state in a pair of accommodating portions S formed on both sides of the chest support portion 3. Since the breast is in a drooping state in this way, the accuracy of diagnosis of breast cancer and regional lymph node groups can be improved.
Since the support jig 1 has a two-layer structure of a base and an upper layer, the base ensures a height at which the breast of the subject H does not come into contact with the bed, and the upper layer according to the subject H Can eliminate physical fatigue and local pressure caused by prone position.
By forming the recess 21 in the head support portion 2, the support area of the subject H can be increased and the load on the clavicle can be dispersed. Further, the position where the subject H is in the prone position can be fixed.
By providing the abdomen support part 4 with the chest support part length adjusting means 10, the connection length N of the chest support part 3 can be adjusted according to the physique of the subject H.
By adopting a configuration including the leg support 5, the burden on the waist of the subject H can be reduced. In addition, since the knees and toes contact with the bed B instead of the support jig 1, the posture of the subject H in the prone position can be stabilized.
By adopting a configuration including the gripping unit 6, the subject H can stably hold the posture in the prone position without being burdened during the PET examination.

  In addition, this embodiment is not limited to the said embodiment, A various change implementation can be performed in the range which the technical idea covers.

  In the present embodiment, the configuration is provided with the chest support portion length adjusting means 10 for adjusting the connection length N of the chest support portion 3 according to the subject's physique, but the physique of the subject H is provided. Accordingly, various portions of the support jig 1 can be adjusted. For example, the base height L may be adjustable.

In the present embodiment, the support jig 1 is configured to be placed on the bed B. However, for example, by providing a stopper or Velcro (registered trademark), the support jig 1 can be detachably fixed to the bed. It is good also as a structure. In the case of such a configuration, it can be used as a fixing means for fixing the adjusted connection length N of the chest support 3.
The support jig 1 of this embodiment can also be used when treating a patient's breast cancer by irradiating radiation. That is, radiation is irradiated to the breast cancer of the patient who is in the prone position as described above on the support jig 1 placed on the bed of the radiation irradiation apparatus.

  Another embodiment of the female breast support jig of the present invention will be described with reference to FIG. The support jig 1A of the present embodiment has a configuration in which a suction device 30 is newly provided on the support jig 1 shown in FIG. As shown in FIG. 6, the suction device 30 includes a suction case 31 installed in each housing portion S of the support jig 1 </ b> A, an exhaust pipe 32 communicating with the inside of each suction case S, and an exhaust pipe 32. An exhaust pump 33 that communicates with the exhaust pump 33 is provided.

  As shown in FIG. 7, the suction case 31 is a box-shaped case having an opening at the upper end so that a breast can be inserted. Similar to the housing part S, the suction case 31 has a depth at which the breast of the subject H does not contact and the size of the opening. Since the suction case 31 needs to be sealed inside by bringing its upper end into contact with the skin of the subject H (or test clothing K) at the time of suction, the opening has elasticity such as rubber. It is formed by the provided member.

The exhaust pipe 32 connects the inside of the suction case 31 and the exhaust pump 33 and is attached to the abdomen support part 4.
The exhaust pump 33 exhausts the air in the space surrounded by the suction case 31 and the skin of the subject H (or the test wear K) through the exhaust pipe 32 to make the inside of the suction case 31 have a negative pressure. Is. The exhaust pump 33 is not particularly limited as long as the inside of the suction case 31 can be reduced to an atmospheric pressure or lower. For example, a dry vacuum pump that does not use pump oil can be used.

  When such a suction device 30 is used to decompress the inside of the suction case 31 whose opening is blocked by the skin of the subject H who is in the prone position (or the examination dress K), the subject is examined along with the decompression. The volume of the breast of the person H increases. By increasing the volume of the breast, the breast tissue near the nipple where the mammary gland is concentrated is enlarged. On the other hand, the tumor cells are aggregated in the living body, and the rate at which the tumor cells are enlarged as the volume of the breast tissue increases is small. Therefore, the contrast between normal cells and tumor cells can be made clearer in the tomographic image created based on the detection signal obtained in the examination. Further, by sucking the breast, a teat on which a radiopharmaceutical (for example, FDG) is likely to accumulate can be pulled out from the root to the outside. As a result, the tumor present in the vicinity of the nipple can be separated from the nipple, and the influence of the radiopharmaceutical accumulated in the nipple can be eliminated, so that the tumor present in the vicinity of the nipple can be accurately diagnosed. Such an action is particularly effective in a PET test that detects tumor cells using the accumulation of FDG. Note that the volume of the breast when the pressure inside the suction case 31 is reduced is only slightly changed and does not change greatly.
