（イ）産業上の利用分野
本発明は、医療分野において、生体の硬さを検知でき、
腫瘍の良否判定等に好適な生体硬さセンサーに関する。[Detailed description of the invention] (a) Industrial application field The present invention can detect the hardness of a living body in the medical field.
The present invention relates to a biological hardness sensor suitable for determining the quality of tumors, etc.

載されているように、従来、金属やプラスチック等の種
々の材料の硬さを測定するものはあった。(b) Conventional technology As described in "Physics and Chemistry Dictionary" published by Iwanami Shoten, pages 245-246, there have conventionally been methods for measuring the hardness of various materials such as metals and plastics.
しかしながら、生体の硬さを測定できるものはなく、こ
のため、医療分野において、例えば、癌の診察を行なう
場合は、医師が指で直接患部に触れ、その硬さを判断し
ていた。However, there is nothing that can measure the hardness of a living body, and for this reason, in the medical field, for example, when examining cancer patients, doctors touch the affected area directly with their fingers to judge its hardness.
（ハ）発明が解決しようとする問題点
従来、医師は指先の感覚と経験に頼って、生体の硬さを
判断するしかなかったので、確実に生体の硬さを把握す

の状態を明確に知ることはできなかった。(c) Problems to be solved by the invention In the past, doctors had no choice but to judge the hardness of a living body by relying on the sensation of their fingertips and experience, so they were unable to accurately grasp the hardness of a living body. For this reason, even experienced doctors were unable to clearly determine the condition of the affected area.

A biological hardness sensor is constituted by a deflection sensor embedded inside a substance and a back plate supporting the elastic material, and the degree of deformation of the deflection sensor by the probe tip when pressure l is applied from the back plate side is determined. from,
It is designed to detect the hardness of the measurement site.

生体の測定部位の硬さを知ることができる。(E) Function In the present invention, when the probe tip is brought into contact with the measurement site of the living body and pressure is applied from the back plate side, the peripheral pressing plate presses the periphery of the measurement site, and the probe tip presses the measurement site and presses the measurement site. Along with the recess, the part receives a repulsive force from that part and shrinks into the inside of the elastic material. As a result, the elastic material deforms and, accordingly,
The embedded deflection sensor deforms. The repulsive force of the living body is proportional to the hardness of the living body, and the degree of deformation of the deflection sensor changes according to this repulsive force, so the stiffness of the measurement site of the living body can be determined from the degree of deformation.

納部に収納されている。In the drawings, (1) is a rice ball-shaped or spherical shape, and is a hard material for suppressing the measurement site of the living body, for example,
Metal probe tip, +21 is a plastic peripheral pressure plate that presses the periphery of the measurement area to normalize the repulsive force received by probe tip (1), and (3) is a silicone plate to support probe tip (1). It is an elastic substance such as rubber, and this elastic substance is surrounded by a peripheral pressing plate (2), a side plate (4) formed continuously with this peripheral pressing plate (2), and a back plate (5). It is stored in the storage compartment.

するためのリード線（８）が接続されている。A deflection sensor (6) such as a strain cage whose resistance value changes with deflection is embedded in the elastic material (3) at a position behind the probe tip (1).
) is connected to a lead wire (8) for inputting a signal corresponding to the amount of deformation to the resistance meter (7).
又、裏面板（５）は、撓みセンサー（６）の変形が、背
後の状態により影響されないように、変形の少な〜・材
質例えば、硬質プラスチックで構成されている。The back plate (5) is made of a material that is less deformable, such as hard plastic, so that the deformation of the deflection sensor (6) is not affected by the conditions behind it.

する。However, since the probe tip (1) is supported by the elastic material (3), the repulsive force of the living body (9) is applied to the probe tip (1), and the probe tip (1) is supported by the elastic material (3). decrease inside. Therefore, the deflection sensor (6) is deformed and its resistance value changes.
生体（９）の反発力は、測定部位が硬いときには大きく
