A retractable medical instrument control mechanism, the medical instrument has a retractable axial direction intersected with the patient to form an insertion point, the control mechanism includes a base, a first rotary module, a second rotary module, a connecting rod module having a near end connecting rod group and a far end connecting rod group, and a retractable drive module, the retractable drive module is located far away from the medical instrument, that is, far away from the insertion point of the patient, such that the medical instrument can perform retractable action, increasing the operating space near the insertion point of the patient.本發明為一種具可伸縮性的醫療器械控制機構,適用於供一醫療器械設置,該醫療器械具有伸縮軸向,且該伸縮軸向與病患相交形成一插入點,該控制機構係由基座、第一旋轉模組、第二旋轉模組、包含相互組設的近端連桿組和遠端連桿組的連桿模組、及伸縮帶動模組所組成,本發明將用以帶動該醫療器械沿該伸縮軸向往復位移的伸縮帶動模組設置在遠離該醫療器械之處,藉以遠離病患的插入點,使得在醫療器械以及病患插入點附近並無致動器的設置,即可控制醫療器械進行伸縮動作,以增加病患插入點附近的操作空間,提升醫師進行微創手術時的便利性。20‧‧‧基座31‧‧‧第一軸向32‧‧‧第一馬達332‧‧‧第一輸出軸41‧‧‧第二軸向42‧‧‧第二馬達432‧‧‧第二樞軸50‧‧‧連桿模組51‧‧‧近端連桿組511‧‧‧第一近端滑軌512‧‧‧第二近端滑軌514‧‧‧第一滑塊515‧‧‧第二滑塊52‧‧‧遠端連桿組521‧‧‧第一遠端桿部522‧‧‧第二遠端桿部60‧‧‧伸縮帶動模組61‧‧‧螺桿62‧‧‧螺帽63‧‧‧第三馬達91‧‧‧醫療器械911‧‧‧伸縮軸向P‧‧‧插入點96‧‧‧基架
