A bendable surgical instrument with for suturing meniscus includes an outer tube, and bendable inner puncture tube inserted into the outer tube. The inner puncture tube has an inflexible tube segment, and a flexible tube segment connected to the inflexible tube segment. The flexible tube segment has opposite two outer half-circumferential surfaces, one of which is formed with a plurality of notches spaced apart from each other in a longitudinal direction of the flexible tube segment and extending in a radial direction of the flexible segment. The flexible tube segment is changeable between a retracted state, where the flexible tube segment is fully retracted back into the outer tube, and an expanded state, where the flexible tube segment extends out of the outer tube and becomes bent. By adjusting the length and curvature of the flexible tube segment out of the outer tube, the bendable surgical instrument can conveniently provide various curvatures matched to the requirements for surgery.一種可變角度之半月軟骨縫合手術器械,包含一外管,及一插裝於外管中之穿刺內管。穿刺內管具有一定形區段,及一可彈性彎曲變形之可彎區段,可彎區段具有徑向相背之一內彎半側與一外彎半側,且內彎半側徑向穿設有多個沿其長向間隔排列的切口。可彎區段能夠於一個內縮在外管中而彈性變形伸直之內縮狀態,及一突伸出外管外並朝向內彎半側彈性彎曲變形之外彎狀態間變化。藉由調整可彎區段突伸出外管之長度以改變彎曲角度的設計,使得本發明半月軟骨縫合手術器械穿具有多個彎曲角度可供選擇使用,可方便依據手術需求調整所需角度,相當方便。4‧‧‧外管41‧‧‧開放端5‧‧‧穿刺內管51‧‧‧定形區段52‧‧‧可彎區段521‧‧‧內彎半側522‧‧‧切口523‧‧‧軸側切面524‧‧‧擋塊部525‧‧‧外彎半側526‧‧‧外露部位53‧‧‧穿刺尖段530‧‧‧穿刺端面900‧‧‧縫線工具901‧‧‧縫線902‧‧‧卡扣定位件
