    • A wound protector and retractor device 1 comprises a sleeve 2, a distal member provided by a distal ring 3 of resilient material and a proximal member provided by a proximal ring 4. The sleeve 2 is led around the ring 3 and is free to move axially relative to the distal ring 3 somewhat in the manner of a pulley. The proximal ring 4 is fixed to the sleeve 2, in this case at the proximal inner end thereof. The sleeve 2 terminates in a handle or gripping portion which is reinforced by a gripping ring 15. The sleeve extends from the proximal ring 4 and the distal ring 3 is contained between inner and outer layers 2a, 2b of the sleeve 2. The resilient distal ring 3 is scrunched up and inserted through the incision 6. The sleeve 2 is then pulled upwardly. On pulling of the sleeve 2 upwardly the outer layer 2b is pulled up while the inner layer 2a is drawn around the proximal ring 3. This results in shortening the axial extent between the proximal ring 4 and the distal ring 3, tensioning the sleeve and applying a retraction force to the margins of the incision 6. As the incision is being retracted the margins are also protected by the sleeve. On retraction, an access port is provided, for example for a surgeon to insert his hand and/or an instrument to perform a procedure. The device may be used as a retractor in open surgery or as a base for a valve/seal to allow it to be used in hand assisted laparoscopic surgery or for instrument access or hand access generally.
    • 伤口保护器和收缩器装置1包括套筒2,由弹性材料的远端环3提供的远端构件和由近端环4提供的近端构件。 套筒2围绕环3引导,并且以滑轮的方式相对于远端环3自由地轴向移动。 近端环4固定到套筒2,在这种情况下,其在近端的内端。 套筒2终止于由夹紧环15加强的手柄或夹持部分。 套筒从近端环4延伸,并且远端环3容纳在套筒2的内层2a和外层2b之间。 弹性远端环3被刮出并穿过切口6插入。 然后将套筒2向上拉。 当将套筒2向上拉时,外层2b被拉起,而内层2a围绕近端环3被拉出。 这导致缩短近端环4和远端环3之间的轴向范围,张紧套管并向切口6的边缘施加缩回力。 当切口正在缩回时,边缘也被套筒保护。 在撤回时,提供进入端口,例如外科医生插入他的手和/或仪器以执行程序。 该装置可以用作开放手术中的牵开器或用作阀/密封件的基座,以允许其用于手动辅助腹腔镜手术或通常用于仪器进入或手动进入。
