Embodiment Construction

[0019] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Such as figure 1 , 2 As shown, the leakage drainage device for rectal anastomosis in this embodiment includes an intestinal holding and drainage device 1 and a drainage operating rod 2, and an orientation adjustment ball 3 is arranged between the intestinal holding and drainage device and the drainage operating rod, so that both They can be connected by relative rotation, so as to realize the adjustment of the orientation of the intestine clamping drainage device in the body cavity. A rotating ball 6 is arranged between the holding fingers so that the two can rotate relative to each other. The driving capsule is fixed on the outside of the two elastic holding fingers to drive the two elastic holding fingers to carry out the holding operation. At the same time, the two elastic holding fingers It is an elastic capsule, and a permeabl...

Abstract

The invention discloses a drainage device for rectal anastomotic leakage, which belongs to the technical field of medical equipment, and comprises an intestinal clamping drainage device and a drainage operation rod rotatably connected with the intestinal clamping drainage device. The intestinal clamping drainage device includes two Two elastic clamping fingers and a driving capsule, the two elastic clamping fingers are elastic capsules, and a permeable membrane is arranged inside the elastic capsules, the elastic clamping fingers communicate with the negative pressure device, and the driving capsule and the positive pressure The device is connected. When it is not inflated, the elastic clamping finger and the driving capsule are in a long strip shape. After inflation, the driving capsule expands into a semi-circular shape, and drives two elastic capsules to form a semi-circular shape to hold the rectum. . Driven by the driving capsule, the inner side wall of the elastic clamping finger can form a close grip on the outer wall of the human intestinal tract to prevent the relative sliding between it and the intestinal tract to cause excrement to seep out, and use the permeable membrane on the inner side to It is fully absorbed and penetrated into the capsule body to be sucked away by the negative pressure device, and its drainage effect is obviously improved compared with the prior art.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a drainage device for anastomotic leakage after rectal cancer surgery. Background technique [0002] Rectal cancer is a common malignant tumor of the digestive system, and its incidence is increasing year by year. It has become the third most common tumor after lung cancer and gastric cancer. At present, the main treatment is surgery-based comprehensive treatment. In recent years, with the continuous improvement of surgical techniques, higher requirements have been placed on the efficacy and safety of surgical treatment. In the field of rectal cancer surgery, how to improve the safety of surgery on the basis of implementing "radical resection" and ensuring clinical efficacy It is an important topic in rectal cancer surgery to reduce the incidence of complications and reduce the incidence of "second surgery". The most common complication of rectal cancer surgery is "anas...
