    • A compact, low-profile surgical retractor (100) avoids the need for a bulky frame. The retractor includes retractor blade components (110, 120, 130, 140, 150, 160) joined pivotally. A cable (170) is guided by each retractor blade component. A winding mechanism (180), such as a spool, is carried by one of the retractor blade components (120) for winding up the cable to cause the retractor blade components to transition from a closed position to an open position. The winding mechanism may be actuated by a detachable handle (200). The retractor blade components may be unitary, injection-molded pieces. The retractor blade components may be fixed pivotally, such as by pins, or pivotally joined by living hinges. A less-invasive surgical method is also provided in which the retractor is inserted into the body through an incision.
    • 紧凑,低调的外科牵开器(100)避免了对庞大框架的需要。 牵开器包括枢转地接合的牵开器叶片部件(110,120,130,140,​​150,160)。 电缆(170)由每个牵开器叶片部件引导。 牵引器叶片部件(120)中的一个承载卷绕机构(180),例如卷轴,用于卷绕电缆,以使牵开器叶片部件从关闭位置转换到打开位置。 卷绕机构可以由可拆卸的把手(200)致动。 牵开器叶片部件可以是单一的,注塑件。 收缩器叶片部件可以例如通过销枢转地固定,或者通过活动铰链枢转连接。 还提供了一种较少侵入性的手术方法,其中牵开器通过切口插入身体。
