Definitions
- the wire rope for operation is required to have excellent torque transmission (rotation followability) as well as push / pull transmission according to its purpose.
- torque transmission property of the operation wire rope is insufficient, the operation of the operation unit is not reproduced in the treatment unit. Further, particularly in the field of medical equipment, the flexibility of the operating wire rope is required as the diameter of the medical equipment is reduced.
- the twist angle of the side strands or side strands is 15 ° or more.
- the maximum value is determined as the major axis.
- the spiral diameter measured from the measurement direction of the major axis in the direction rotated by 90 ° around the central axis of the side strand or side strand is determined as the minor axis.
- a plurality of spirals are continuously formed along the axial direction of the loosened side strands or side strands. Therefore, the average value of a plurality of measured values (for example, arbitrary 10 locations) is adopted as each diameter in the direction intersecting 90 °.
- the maximum angle difference between the ropes of Example 1-8 and Comparative Example 1-3 is shown in Tables 1 and 2 according to an index when the maximum angle difference of Comparative Example 3 is 100.

Abstract
Description
図1に示された構成を備えた実施例1-8の各操作用ワイヤロープを得た。これらのロープは、医療機器用のワイヤロープである。全ての素線の材質が、SUS304オーステナイト系ステンレス鋼である。ロープの外径(コード径)は0.8mm、芯線の外径は0.28mm、及び、側素線の外径は0.26mmである。いずれの素線も、その引っ張り強度は2812MPaである。これらのロープの撚り構成はいずれも1+6の層撚りであり、撚りピッチはいずれも5.8mmである。実施例1-8のロープの熱処理温度は、いずれも550°Cである。実施例1-8のロープの側素線の扁平度及び初期伸びは、表1及び表2に示されるとおりである。
扁平度及び初期伸びが表2に示されるとおりである他は実施例1と同様にして、比較例1の操作用ワイヤロープを得た。この比較例1のロープの側素線は、扁平形状にはされていない。
扁平度及び初期伸びが表2に示されるとおりであり、コード径が0.8mmを大幅に超えている他は実施例1と同様にして、比較例2の操作用ワイヤロープを得た。表2に示されるとおり、比較例2のロープは、その扁平度が1.50とされたため、素線間に多くの空隙が生じる、いわゆるオープン構造となった。このため、コード径が0.8mmを大幅に超えた。かかる比較例2のロープは、医療機器用の操作用ワイヤロープとしての呈を成しておらず、医療機器用の操作用ワイヤロープとしての使用は不可能であると判断された。
比較例3は、従来技術に係る操作用ワイヤロープである。この比較例3の操作用ワイヤロープは、扁平度及び初期伸びが表2に示されるとおりである他は、実施例1と同等である。この比較例3のロープの側素線は、扁平形状にはされていない。
トルク伝達性は、各ロープの基端側(操作部に相当)を回転させたときの、基端側の回転角と先端側(処置部に相当)の回転角との差によって評価される。実施例及び比較例の各ロープに対し、以下のごとくトルク伝達性の評価試験が実施された。
4・・・芯線
6、14、20・・・側素線
10・・・素線
12、18・・・コアストランド
Claims (4)
- 最外層である側素線又は側ストランドが呈しているスパイラル形状の、長径を短径で除した縦横比である扁平度が、1.00を超え1.10以下である操作用ロープ。
- 破断荷重の1.0%の引っ張り荷重が負荷されたときの伸び率が、0.04%以上0.10%以下である請求項1に記載の操作用ロープ。
- 上記扁平度が、1.01以上1.05以下である請求項1又は2に記載の操作用ロープ。
- 上記側素線又は側ストランドの撚り角が、15°以上である請求項1から3のいずれかに記載の操作用ロープ。
