| 摘要 |
The present invention relates to a percutaneous sigmoid volvulus deflation device comprising a catheter means having a principal channel for drainage and optionally irrigation; inflatable balloon means in proximity to the distal end of the principal catheter channel and provided with an inflation fluid supply channel and skirt means in proximity to the rear of the said balloon means for trapping of an annular portion of the colon wall therebetween when the device is in use and the skirt is in a deployed condition. To use the device, the distal end of the main catheter channel and the balloon means are introduced into the colon with the balloon means in a deflated condition, the balloon means inflated and the skirt released for trapping an annular colon wall portion between the balloon means and skirt thereby to minimise the risk of leak of the colonic contents. The high pressure in the generated by gas entrapment colon may be relieved by venting through the principal catheter channel. |
