Abstract: A retractor system, kit and method of use includes a plurality of retractors for use in retracting a wound during a minimally-invasive hip replacement surgery to define an access space to a surgical site is discussed. Each of the retractors comprises a handle portion configured to be held by a user, a curved bend portion distal of the handle portion, and a wound contact portion attached to the curved bend portion. The wound contact portion is configured to contact tissue of the wound when at least a portion of the retractor is inserted through a skin incision that defines the wound. Each retractor also has a distal portion disposed distally of the wound contact portion, wherein the wound contact portion has a generally curved cross-sectional profile perpendicular to its length that is configured to prevent necrosis of the tissue during retraction. In addition, the cross-sectional profile provides an improved line of sight during the surgical procedure. Furthermore, the cross-sectional profile prevents the jamming of a cutting device, such as a reamer inserted through the incision, while the retractors retract the wound.

Abstract translation: 卷收器系统，套件和使用方法包括多个牵开器，用于在微创髋关节置换手术期间缩回伤口以限定到手术部位的进入空间。 每个牵开器包括构造成由使用者保持的手柄部分，在手柄部分的远侧的弯曲弯曲部分和附接到弯曲弯曲部分的缠绕接触部分。 卷绕接触部分构造成当牵开器的至少一部分穿过限定伤口的皮肤切口插入时接触伤口的组织。 每个牵开器还具有远离所述伤口接触部分的远侧部分，其中所述缠绕接触部分具有垂直于其长度的大致弯曲的横截面轮廓，所述截面轮廓被构造成防止在缩回期间组织的坏死。 此外，横截面轮廓在外科手术期间提供改善的视线。 此外，横截面轮廓防止当牵开器缩回伤口时切割装置（例如通过切口插入的铰刀）的卡住。
