<p>An instrument for colon and rectum resection and a subsequent anastomosis permits an aseptic and easy operation. The instrument comprises a diathermy snare (1) supported on a rigid support snare (3) which makes it possible to perform a precise location of the diathermy snare (1). The instrument has an extraction wire (8) provided with a circular end section (9) having a diameter smaller than the diameter of the possible opening of the support and diathermy snare (3, 1). The support snare is introduced via two guides (4) in a tubular connection means (6) which is also connected to the extraction wire (8). The instrument is introduced via anus to the diseased intestine section (19). The end section (9) is displaced through the support and diathermy snare and the intestine is fixed hereto whereafter an invagination is performed. The intestine is sutured without being opened whereafter the support snare is removed and the diathermy snare (1) is constricted around the intestine and the latter is cut off. The invaginated intestine may hereafter be extracted via anus together with the instrument. Thus, the intestine has not been opened during the operation.</p> |
