Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a convenient and fast used dilator for anastomotic stoma after rectal surgery.
Background
China is a country with high incidence of colorectal cancer, the proportion of patients with low rectal cancer is increased year by year, with the technical progress, many of the patients who cannot protect the anus before adopt a low-position anastomotic anus protecting technology, the rectum has about 12-15 centimeters and can be divided into high-position rectal cancer, middle-position rectal cancer and low-position rectal cancer, generally, the patients with pathological changes with the distance of less than 5-7 centimeters from the anal margin are regarded as the low-position rectal cancer, in the operation process, the cancerous sections need to be excised, and then two sections of the rectum without pathological changes are anastomosed. The anastomoses at the low position are caused by weak blood supply of intestinal canals, local inflammation, anus waste caused by protective stoma after three months of operation and the like, and often cause anastomotic stenosis.
At present, no special expansion instrument special for anastomotic stenosis after low-position rectal surgery exists clinically. Still use medical staff's artificial expansion as the main, or adopt DSA guide lower sacculus dilatation, its price is expensive, and the consumptive material has not repeatability, can't be implemented outside the medical unit by oneself; the current balloon can only expand one rectum, and cannot simultaneously expand two rectum; moreover, before the expansion, the balloon has a small volume, so that the balloon can conveniently enter the rectum, but after the expansion, when the balloon needs to be taken out from the rectum, the balloon needs to be deflated, but cannot be restored to the original shape, so that the rectum of the patient can be damaged to some extent in the taking-out process; the current saccule is generally expanded by inflating or injecting water, so that in the use process, one hand is needed to control the advancing depth of the saccule, and the other hand is needed to control an inflating pump or a water injection needle tube; the intestinal canal condition is indirectly displayed through intermittent radiography, and the operation is carried out under non-direct-view monitoring, so that inaccurate operation or error occurs, or other people are required to cooperate; therefore, how to overcome the above technical problems and disadvantages is a problem to be solved.
