Description

本発明は、生検用の組織標本を採取するシステム（装置）の技術に関する。   The present invention relates to a technique of a system (device) for collecting a tissue specimen for biopsy.

生検とは、生体から組織の小切片を切り取って、病理学的に調べることをいい、医師による診断の確定のために行われ、特に悪性腫瘍の診断のためには不可欠である。また、穿刺針を用いて試料を採取することを針生検といい（広辞苑第六版）、針生検の対象となる臓器には、乳腺、リンパ節、甲状腺などがある。
近年、上記のような生検を行うことを目的としたシステム（装置）に関する技術の提案が多数なされている（特許文献１、２など）。 Biopsy refers to examining a pathologically by cutting a small section of tissue from a living body, and is performed for confirmation of diagnosis by a doctor, and is particularly essential for diagnosis of malignant tumor. Collecting a sample using a puncture needle is called needle biopsy (Kojien 6th edition), and organs to be subjected to needle biopsy include mammary gland, lymph node, thyroid gland and the like.
In recent years, many proposals have been made on technologies related to systems (devices) for the purpose of performing biopsy as described above (Patent Documents 1 and 2, etc.).

一方、人の組織は軟らかいものから硬いものまで種々のものがある。生検の対象を、例えば、乳腺組織とした場合、皮膚及び脂肪は軟らかいため問題は生じないが、乳腺組織そのものは繊維性の成分が多く、組織採取用の針状器具（生検針）を刺すことが困難なときもある。また、生検の対象を乳腺組織とした場合に、大きな腫瘤に対し生検針を刺すことは比較的容易であるが、問題となるのは、腫瘤の大きさが１ｃｍ以下、特に、０．５ｃｍ程度の場合であって、この大きさの腫瘤になると、硬い乳腺組織の中にある腫瘤に生検針を当てることが難しい。
他方、上記のような組織採取が難しいという事態を打開する対策としては、生検針を細くし抵抗を減らした上で組織採取を行うという方策が取られている。 On the other hand, there are various human tissues ranging from soft to hard. For example, when the target of biopsy is mammary gland tissue, there is no problem because the skin and fat are soft. Sometimes it is difficult. In addition, when the biopsy target is a mammary gland tissue, it is relatively easy to stab a biopsy needle into a large mass, but the problem is that the size of the mass is 1 cm or less, particularly 0.5 cm. In this case, it is difficult to apply a biopsy needle to a tumor in hard mammary gland tissue.
On the other hand, as a measure for overcoming the situation in which it is difficult to collect tissue as described above, a measure is taken to collect tissue after reducing the resistance by reducing the biopsy needle.

しかしながら、上記技術のように、生検針を細くすると採取される組織の量が少なくなり、もともと小さい腫瘤の採取を狙っていることとも相まって、採取される組織が少量であれば、病理診断が困難になるという問題点がある。   However, if the biopsy needle is made narrower as in the above technique, the amount of tissue collected is reduced, and coupled with the aim of collecting small tumors, pathological diagnosis is difficult if the collected tissue is small. There is a problem of becoming.

そこで本発明では、上記問題点に鑑み、生検用の採取対象組織が硬い場合であっても、比較的太い針状器具（生検針）を用いることによって、採取される組織の量を確保し、医師による診断率を向上させる生検用組織標本採取システムおよび当該システムの制御方法を提供することを目的とする。   Therefore, in the present invention, in view of the above problems, even when the tissue to be collected for biopsy is hard, the amount of tissue to be collected is ensured by using a relatively thick needle-like instrument (biopsy needle). An object of the present invention is to provide a biopsy tissue sample collection system that improves the diagnosis rate by a doctor and a control method of the system.

(Structure of tissue specimen collection system for biopsy according to the present embodiment)

図１及び図２を用いて、本実施の形態に係る生検用組織標本採取システム（以下、単に「生検システム」という。）１００の構造について、従来の生検システム２００の構造と比較しながら説明する。図１は、生検システム２００の概要を説明する図であり、図２は、生検システム１００の概要を説明する図である。   1 and 2, the structure of a biopsy tissue sampling system (hereinafter simply referred to as “biopsy system”) 100 according to the present embodiment is compared with the structure of a conventional biopsy system 200. While explaining. FIG. 1 is a diagram illustrating an outline of the biopsy system 200, and FIG. 2 is a diagram illustrating an outline of the biopsy system 100.

はじめに、従来の生検システム２００について説明する。図１で示すように、生検システム２００は、針状器具２１０、生検装置２２０、操作手段２３０を有する。針状器具２１０は、中空であって、細長い針のような形状をしており、生検用の組織標本を採取するために、患者に刺入して使用する。   First, a conventional biopsy system 200 will be described. As shown in FIG. 1, the biopsy system 200 includes a needle-like instrument 210, a biopsy device 220, and operation means 230. The needle-like instrument 210 is hollow and shaped like an elongated needle, and is inserted into a patient and used to collect a tissue specimen for biopsy.

生検装置２２０は、針状器具２１０を保持し、後述する操作手段２３０を介して、針状器具２１０の生検用組織標本の採取動作を制御する役割を果たす部位である。   The biopsy device 220 is a part that holds the needle-like instrument 210 and plays a role of controlling the operation of collecting the biopsy tissue specimen of the needle-like instrument 210 via the operation means 230 described later.

操作手段２３０は、生検装置２２０に含まれる部位であり、例えば、ユーザ（医師）による操作手段２３０の押下操作などが行われたことをトリガーとして、針状器具２１０による生検用組織標本の採取動作が開始されるなど、ユーザ（医師）と生検システム２００とのインターフェース機能を発揮する部位である。   The operation means 230 is a part included in the biopsy device 220. For example, when the user (physician) depresses the operation means 230, the operation means 230 triggers the biopsy tissue specimen by the needle-like instrument 210. This is a part that exhibits an interface function between the user (physician) and the biopsy system 200, such as when a sampling operation is started.

生検システム２００は、上記のような構成を有しており、針状器具２１０を患者に刺し入れ、針状器具２１０の中空部分に患者の組織標本を採取することで、医師による病理診断を可能にしている。   The biopsy system 200 has the above-described configuration. The needle-like instrument 210 is inserted into the patient, and a tissue specimen of the patient is collected in the hollow part of the needle-like instrument 210, so that a pathological diagnosis by a doctor can be performed. It is possible.

しかしながら、生検システム２００においては、病理診断を行う部位の組織が硬い場合、生検針を細くし組織採取を行うが、生検針を細くすると採取される組織の量が少なくなり、病理診断が困難になる。   However, in the biopsy system 200, when the tissue of the site where the pathological diagnosis is performed is hard, the biopsy needle is thinned and the tissue is collected. However, if the biopsy needle is thinned, the amount of the collected tissue is reduced and the pathological diagnosis is difficult. become.

そこで、生検システム１００は、患者（患部）に刺し入れる針状器具１１０が振動するように制御することによって、組織標本採取時の針状器具１１０の患部に対する抵抗を減らす。こうすることによって、生検システム１００は、比較的口径の大きい（太い）針状器具１１０での微小病変の正確な穿刺を容易にし、より多くの組織採取を可能にする。   Therefore, the biopsy system 100 reduces the resistance of the needle-like instrument 110 to the affected part when collecting the tissue specimen by controlling the needle-like instrument 110 inserted into the patient (affected part) to vibrate. By doing so, the biopsy system 100 facilitates accurate puncture of a micro-lesion with a relatively large (thick) needle-like instrument 110 and allows more tissue collection.

図２で示すように、生検システム１００は、針状器具１１０、生検装置１２０、操作手段１３０、振動付与手段１４０を有する。針状器具１１０は、中空であって、細長い針のような形状をしており、生検用の組織標本を採取するために、患者に刺入して使用する。   As shown in FIG. 2, the biopsy system 100 includes a needle-like instrument 110, a biopsy device 120, an operation unit 130, and a vibration applying unit 140. The needle-like instrument 110 is hollow and has a shape like an elongated needle, and is inserted into a patient for use in obtaining a tissue specimen for biopsy.

生検装置１２０は、針状器具１１０を保持し、後述する操作手段１３０を介して、針状器具１１０の生検用組織標本の採取動作を制御する役割を果たす部位である。   The biopsy device 120 is a part that holds the needle-like instrument 110 and plays a role of controlling the operation of collecting the tissue specimen for biopsy of the needle-like instrument 110 via the operation means 130 described later.

操作手段１３０は、生検装置１２０に含まれる部位であり、例えば、ユーザ（医師）による操作手段１３０の押下操作などが行われたことをトリガーとして、針状器具１１０による生検用組織標本の採取動作が開始されるなど、ユーザ（医師）と生検システム１００とのインターフェース機能を発揮する部位である。   The operation means 130 is a part included in the biopsy device 120. For example, when the user (physician) depresses the operation means 130, the operation means 130 triggers the biopsy tissue sample by the needle-like instrument 110. This is a part that exhibits an interface function between the user (physician) and the biopsy system 100, such as the start of the collection operation.

振動付与手段１４０は、針状器具１１０を所定の振動数で振動させる機能を果たす器具である。振動付与手段１４０は、例えば、バイブレータ（Vibrator）と呼ばれる器具であって、モーターの軸に重心を偏らせた重りを取り付け、回転させることで振動を生むものである。   The vibration applying means 140 is an instrument that functions to vibrate the needle-like instrument 110 at a predetermined frequency. The vibration applying means 140 is, for example, an instrument called a vibrator, and generates vibration by attaching and rotating a weight with a biased center of gravity on the shaft of the motor.

振動付与手段１４０は、針状器具１１０に対し直接的に振動を付与する形態であっても良く、例えば、生検装置１２０を介して、針状器具１１０に対し間接的に振動を付与する形態であっても良い。従って、振動付与手段１４０は、図２で示すように、針状器具１１０に装着される形態であっても良く、生検装置１２０の側面に装着される形態であっても良い。また、振動付与手段は、図２で示すように、生検装置１２０に内蔵される形態であっても良い。   The vibration imparting means 140 may be configured to directly impart vibration to the needle-shaped instrument 110, for example, form configured to indirectly impart vibration to the needle-shaped instrument 110 via the biopsy device 120. It may be. Therefore, as shown in FIG. 2, the vibration applying means 140 may be mounted on the needle-like instrument 110 or may be mounted on the side surface of the biopsy device 120. Further, as shown in FIG. 2, the vibration applying means may be in a form built in the biopsy device 120.

図３で示すように、振動付与手段１４０は、針状器具１１０について、ランダムな方向に振動を付与する形態であっても良く、針状器具１１０の患部への刺し入れ方向に振動を付与する形態であっても良く、また、針状器具１１０の患部への刺し入れ方向と直交する方向に振動を付与する形態であっても良い。   As shown in FIG. 3, the vibration imparting means 140 may be configured to impart vibration in a random direction with respect to the needle-like instrument 110, and imparts vibration in the direction in which the needle-like instrument 110 is inserted into the affected area. The form may be sufficient, and the form which provides a vibration in the direction orthogonal to the insertion direction to the affected part of the needle-shaped instrument 110 may be sufficient.

上記のように、生検システム１００は、患者に刺し入れる針状器具１１０が振動するように制御することによって、組織標本採取時の針状器具１１０の患部に対する抵抗を減らすことができる。こうすることによって、生検システム１００は、比較的口径の大きい（太い）針状器具１１０での微小病変の正確な穿刺を容易にし、より多くの組織採取を可能にする。
（本実施の形態に係る生検用組織標本採取システムの使用方法） As described above, the biopsy system 100 can reduce the resistance to the affected part of the needle-like instrument 110 during tissue sampling by controlling the needle-like instrument 110 inserted into the patient to vibrate. By doing so, the biopsy system 100 facilitates accurate puncture of a micro-lesion with a relatively large (thick) needle-like instrument 110 and allows more tissue collection.
(Usage method of tissue sample collection system for biopsy according to the present embodiment)

図２乃至図６を用いて、生検システム１００の使用方法について説明する。図４は、採取する組織（病変組織）と生検システム１００（又は針状器具１１０）との関係を示す図であり、図５及び図６は、針状器具１１０の拡大図である。   A method of using the biopsy system 100 will be described with reference to FIGS. 4 is a diagram showing the relationship between the tissue to be collected (lesioned tissue) and the biopsy system 100 (or the needle-like instrument 110), and FIGS. 5 and 6 are enlarged views of the needle-like instrument 110. FIG.

はじめに、ユーザ（医師）操作に従い振動付与手段１４０によって、直接的又は間接的に、針状器具１１０が振動するように制御する。このようにすることで、針状器具１１０の患部刺し入れ時の抵抗を減らすことができるため、患部が乳腺組織のように硬い場合でもあっても、比較的広口径の針状器具１１０を使用することができ、微小病変の正確な穿刺を可能とする。   First, it controls so that the needle-shaped instrument 110 may vibrate directly or indirectly by the vibration imparting means 140 according to a user (doctor) operation. By doing so, the resistance at the time of insertion of the affected part of the needle-shaped instrument 110 can be reduced, so that the needle-shaped instrument 110 having a relatively wide diameter is used even if the affected part is hard like breast tissue. And allows accurate puncture of microlesions.

次に、図４で示すように、ユーザ（医師）が、イメージ下（超音波、Ｘ線、ＣＴ等）で、患者の乳腺組織１５０の中に有る病変組織（採取対象組織）１６０の手前まで、生検システム１００の針状器具１１０先端を刺し入れる。   Next, as shown in FIG. 4, the user (physician) moves to the front of the lesion tissue (collection target tissue) 160 in the mammary gland tissue 150 of the patient under the image (ultrasound, X-ray, CT, etc.) The tip of the needle-like instrument 110 of the biopsy system 100 is inserted.

さらに、ユーザ（医師）が、例えば、操作手段１３０の押下操作を行うと、針状器具１１０による生検用組織標本の採取動作が開始される。ここで生検用組織標本の採取動作について説明する。図５で示すように、針状器具１１０の根元部位にあった外筒１１２が、操作手段１３０の押下操作をトリガーにして、図６で示すように、針状器具１１０の先端部位へ移動する。そうすると、外筒１１２及び内針１１４によって病変組織１６０が切り取られ、試料ノッチ１１６内に生検用の採取対象組織（病変組織）１６０が採取される。
最後に、ユーザ（医師）が、試料ノッチ１１６に採取された組織を顕微鏡などで観察することによって、患者に対する診断の確定を行う。 Further, when the user (doctor) performs, for example, a pressing operation of the operation means 130, the biopsy tissue specimen collection operation by the needle-like instrument 110 is started. Here, an operation of collecting a biopsy tissue specimen will be described. As shown in FIG. 5, the outer cylinder 112 at the base part of the needle-like instrument 110 moves to the tip part of the needle-like instrument 110 as shown in FIG. 6, using the pressing operation of the operation means 130 as a trigger. . Then, the diseased tissue 160 is cut out by the outer cylinder 112 and the inner needle 114, and a tissue to be collected (lesioned tissue) 160 for biopsy is collected in the sample notch 116.
Finally, the user (doctor) confirms the diagnosis for the patient by observing the tissue collected in the sample notch 116 with a microscope or the like.

以上、本発明の実施の形態について詳述したが、本発明は係る特定の実施の形態に限定されるものではなく、特許請求の範囲に記載された本発明の要旨の範囲において、種々の変形・変更が可能である。   Although the embodiment of the present invention has been described in detail above, the present invention is not limited to the specific embodiment, and various modifications are possible within the scope of the gist of the present invention described in the claims.・ Change is possible.
