Embodiment Construction

[0014] Below in conjunction with accompanying drawing, the utility model is described further.

[0015] see Figure 1-2 : A kind of intestinal bypass device based on Valtrac anastomotic ring, comprising Valtrace anastomotic ring 1 that can be placed in intestinal tract, described Valtrac anastomotic ring 1 is made up of two opposite hollow mushroom rings 2, and described two mushroom The rings 2 are respectively provided with bayonets and buckles that can be slidably engaged. One of the mushroom rings 2 is sleeved with a soft rubber tube 3 acceptable to the human body, and one end of the soft rubber tube 3 is fixed on the At the junction of the bayonet and buckle of the mushroom ring 2, the soft rubber tube 3 has sufficient length to ensure that the other end of the soft rubber tube 3 can extend beyond the applied intestinal seam 4 and reach the anus 5 outside.

[0016] A groove is left between the two mushroom rings 2 of the Valtrac anastomotic ring 1, and the groove can be...

Abstract

The invention relates to an intestinal bypass device based on Valtrac anastomosis ring, comprising a Valtrac anastomosis ring in the intestinal. The Valtrac anastomosis ring is composed by two opposite hollow mushroom rings. The two mushroom rings are respectively provided with a slideable-locked bayonet and a bayonet catch, and one mushroom ring is sleeved-jointed with a flexible hose accepted by human body, and one end of which is fixed on the connecting part of the bayonet and bayonet catch on the mushroom ring. The flexible hose is long enough to ensure the other end extend outside of the intestinal slit part and the anus. The intestinal bypass device based on Valtrac anastomosis ring has the advantages of no matching leaking port while connecting the rectum, no secondary operation and intestinal fistulization, safety and convenience.

Description

(1) Technical field [0001] The invention relates to a medical device, in particular to a device for preventing colorectal anastomosis leakage used during colorectal anastomosis. (2) Background technology [0002] The success of colorectal anastomosis is the key to anus-preserving surgery for rectal cancer or rectal resection for other benign diseases. Manual or instrumental suture is used for colorectal anastomosis, and there is inevitably a certain incidence of colorectal anastomotic leakage If anastomotic leakage occurs in colorectal anastomosis, that is, feces leak from the colorectal anastomosis, it will pose a serious threat to the patient's life. The problem of colorectal anastomosis leakage has become a major challenge for anus-preserving surgery for low rectal cancer. [0003] Aiming at the leakage of colorectal anastomotic stoma, domestic and foreign researchers have designed and adopted some methods to divert feces to protect the anastomotic stoma, such as temporar...
