Before the operation, the one end that is equipped with sacculus 2 with pipe 1 gets into the intestines through patient's anus, then lead into the pathological change position, make sacculus 2 be in the one end that pathological change intestinal section is close to the stomach, next, inflate sacculus 2 through pipe 1 other end, make sacculus 2 inflation and shutoff patient's intestinal section keep, afterwards, let in gas into patient's body through the anus, make the good inflation of intestinal section between sacculus 2 to the anus, so far, doctor can be smooth carry out operation in the good intestinal section of inflation, the operation of medical personnel is very favorable to in this regard to whole design, can let in gas when the pathological change operation takes place for pathological change intestinal section well inflation, and can not influence intestinal section between pathological change position to the afterbody, ensure the smoothness of operation, improve the success rate of operation, shorten the operation time, alleviate patient's pain and discomfort by a wide margin.
Example two
As shown in fig. 2, the sealer for colorectal surgery of this embodiment includes a catheter 1 and a pressure monitoring system, one end of the catheter 1 is wrapped with an inflatable balloon communicating with an inner cavity of the catheter, and further includes a pressure monitoring system, the pressure monitoring system includes a pressure monitor 3 and a pressure sensor 4, the pressure sensor 4 is disposed on the balloon 2 and is used for detecting the pressure of the balloon 2 in contact with human tissue after inflation, and the pressure sensor 4 is connected with the pressure monitor 3 through a line built in the catheter 1.
In this embodiment, the pressure sensor 4 detects the pressure of the balloon 2 and the endothelial tissue of the intestinal section all the time in the inflation process of the balloon 2, and visually displays on the pressure monitor 3, so that the medical staff can conveniently perform correct operation, and the situation that the intestinal section inner membrane is damaged due to over-air pressure or the intestinal section is blocked due to over-air pressure is avoided.
In this embodiment, the pressure detector 3 is a product of the prior art, the specific model of which is flexibly selected according to the actual use, and the specific structure and function of which are not described herein.
On the basis of the second embodiment, the optimization can be improved under the action of
