The present invention it is possible to hold surely the tooth even with a small force Conventionally, to provide a tooth extraction forceps it is possible to achieve also a reduction in the number required for the size and weight reduction and treatment. A pair of forceps members 1 by being rotatably connected by a pivot 2 in the middle portion in the longitudinal direction, the grip portion 3, which is toward and away from each other operation on the base end portion side of the pivot 2 is formed, in extraction forceps clamping part 5 for holding the tooth to open and close by the contact and separation operation to the tip end of the pivot 2 is formed, the opposing surfaces of the pair of sandwiching portions 5, toward respectively from the distal end to the proximal end by the depth of the width and the opposing surface becomes gradually smaller on the edge 6a with respect to the counter face has a recess 6, which forms a semi-circular or semi-elliptical arc shape.FIELD 1【課題】従来よりも小さな力で歯牙を確実の保持することができるとともに、小型軽量化および治療に必要とされる本数の低減も図ることが可能になる抜歯鉗子を提供する。【解決手段】一対の鉗子部材1が長手方向の中間部において枢軸2によって回動自在に連結されることにより、枢軸2の基端部側に互いに接離操作される把持部3が形成され、枢軸2の先端部側に上記接離操作によって開閉して歯牙を挟持する挟持部5が形成された抜歯鉗子において、一対の挟持部5の対向面に、それぞれ先端から上記基端部側に向けて幅寸法および対向面からの深さ寸法が漸次小さくなることにより、対向面に対する縁部6aが半円弧状または半楕円弧状をなす凹部6を形成した。【選択図】図1
