< Topic > Especially being the torque limiter for the screw driver for the surgery: At least in that inner wall one circumferential groove (12) and the plural concave sections which it runs parallel to the axis (14) outside possessing, the sleeve (10) with The groove (12) one which is inserted or the plural elastic rings (16) with The concave section which is owned the rotary element cage (20) outside accepting, the sleeve (10) by (14) the groove hole of the same number as number (18) one rotary element cage which is attached (20) with The rotary element groove hole (18) the plural rotary elements which are inserted (22) with V letter type which falls well in the rotary element cage, the rotary element groove hole (18) in parallel, to the axis of the same number as number, it runs inside (26) possessing ardently, the sleeve (24) And the rotary element cage (20) with the outer part sleeve (10) being the tool which restricts the relative being twisted between, first acceptance position, namely the outer part sleeve (10) in rotation direction, when as a result this tool transmits twist motion, the rotary element (22) the concave section (14) with becomes one line, transmission torque becomes maximum, single number or the plural elastic rings (16) the first acceptance position which (26) from the inside sleeve (24) enters ardently by pressure and, second acceptance position, namely outsideThe sleeve (10) it is released by revolution, the inside sleeve (24) the rotary element where the top (26) falls ardently well inside (22), the outer part sleeve (10) the concave section above (14) the second acceptance position which modifies the position where it faces, with the tool which restricts the relative being twisted in between and, the torque limiter which it has.< Selective figure > Figure 3【課題】 特に外科用のねじ回しのためのトルクリミッターであって:その内壁に少なくとも一つの円周溝(12)および軸に平行に走る複数の凹部(14)を有する外側スリーブ(10)と;溝(12)に挿入される一つまたは複数の弾性リング(16)と;回転要素ケージ(20)を受入れる外側スリーブ(10)によって所有される凹部(14)の数と同数の溝孔(18)が付いた一つ
