Description
本出願は、2018年3月6日に出願された、「Sheathed Surgical Saw Blade and Bearings」と題する米国仮特許出願第62/639,040号、および2018年8月30日に出願された、「Sheathed Surgical Saw Blade with Bearings and Universal Saw Handpiece for Sheathed and Standard Blades」と題する米国仮特許出願第62/724,914号の優先権を主張し、その全体が本明細書に参照によって組み込まれる。
本発明は一般に、外科手術ブレード組立品に関し、より具体的には、摩耗を最小化するために、外側シースと内側ブレードとの間に隙間量を有する被覆ブレード組立品に関する。
外科手術被覆ブレードは、可動内側部材(ブレード)および外側静止部材(シース)から構成される。使用中、カンチレバー力が組立品に印加されてそれが可動部品および静止部品を接触させるため、可動部材と静止部材との間の接触は不可避である。ブレードの高い線速度のため、組立品は、ブレードが静止シースと接触するときに非常に高温となって摩耗し得る。シースおよびブレードの加熱は、骨壊死、ならびに患者またはユーザの損傷を引き起こす可能性がある。さらに、ブレードがシースと接触することにより作出される摩耗により金属粒子が生成され、これが外科手術部位内に落下する可能性がある。
部分112はまた、円形の開口124を含む遠位端122を含む。図示した実施形態では、底部分112の遠位端122は、そこから延びる一対のアーム126(またはプロング)を含む。アーム126は互いに向かって延びるが接せず、その間にギャップ128を形成する。ギャップ128は、図示するように円形の開口124内に延びる。
Claims (4)
- 近位端から遠位端に延びる被覆ブレード組立品であって、
上部分および底部分を有する外側シースであって、前記上部分および前記底部分の間に内側内腔を有する外側シースと、
