Description
Technical field
The utility model is related to medical instruments field, specially a kind of Inflatable medical anal canal.
Background technology
Anastomotic leakage is the main tired element of one of most common severe complication of rectal cancer surgery and postoperative death.Directly
Intestinal cancer postoperative anastomotic fistula incidence is about 1.3%-23%, most of to think that 10% or so, the death rate is about 1/3.It is often in hand
Occur in postoperative 4-9 days, individuals patients were at 10 days or so.Postoperative preset anal canal per anum drainage is gradually verified with prevention kiss
It heals up the effect of fistula.Most of documents think that preset anal canal is simple and safe, can reduce the incidence of postoperative anastomotic fistula.
Existing anal canal is mostly used cooperatively using with drainage bag, and drainage bag is connected to the port of export of anal canal, when in use, will
The front end of drainage tube is placed into the internal of patient, and the excreta of patient's inner body then flow to drainage bag by drainage tube and collects heel row
Go out.Existing anal canal when in use, can be by the Front-end Design of anal canal into tiny shape, hole in order to mitigate the pain of patient
Interior diameter trumpet anal canal is 0 .4cm, and large size anal canal hole interior diameter is up to 0 .6cm.But during use, due to anal canal
Connector is thin, is susceptible to the phenomenon that stool blocks anal canal；Simultaneously as traditional anal canal side opening is few, cause drainage effect bad；
And in art, particularly under laparoscope, due to the tiny and mechanical limitation of anal canal, it is difficult to observe the essence that anal canal is placed
True position, this causes, and drainage effect is bad, cannot effectively support situations such as previous anastomotic or even play and drainage reverse effect.
Utility model content
