    • A surgical retractor for use in combination with balloon dissection of internal body tissue of a human body part to maintain an operative space created by the dissection of the internal body tissue. The retractor has a frame comprising a base with opposing sides and at least one arcuate body tissue support element extending upwardly from one side to the other side of the base so as to form an arc extending transversely over a human body part wherein internal body tissue is to be balloon dissected. As least one suture anchor element is located along the length of the arcuate support element to allow a tensioning suture extending from separated internal body tissue of the human body part being balloon dissected to be secured thereto to maintain an open operation cavity. The suture tied at one end to the suture anchor element includes a disk or suture button at the other end that is urgingly retained against the top portion of the operation cavity to facilitate maintaining an open cavity for a surgical procedure.
    • 一种手术牵开器,用于与人体部分的内部身体组织的球囊解剖组合以保持通过内部身体组织的解剖产生的手术空间。 牵开器具有框架,该框架包括具有相对侧面的底座和至少一个弓形体组织支撑元件,其从基座的一侧向上延伸到另一侧,以便形成横向延伸到人体部分上的弧,其中, 被气球解剖。 至少一个缝合锚定元件沿着弓形支撑元件的长度定位,以允许从被分离的人体部分的分离的内部主体组织延伸的张紧缝合线被解剖以固定到其上以保持开放的操作腔。 缝合锚定元件的一端处的缝合线包括在另一端的盘或缝线按钮,其被推动地保持抵靠操作腔的顶部,以便于维持用于外科手术的开口腔。
