Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an intestinal anastomosis tube stent. Background Art

[0002] Intestinal resection is a surgical method for treating intestinal diseases or injuries, and is a common surgical means for treating diseases such as intestinal tumors, intestinal perforation or rupture, intestinal torsion or intestinal obstruction.

[0003] During intestinal resection, doctors need to connect the intestine with anastomosis parts or sutures after removing the diseased part, and this operation is intestinal anastomosis. Anastomotic leakage is the most serious complication of intestinal resection surgery. To address this problem, currently in clinical practice, the risk of anastomotic leakage is mostly reduced through diversion stoma surgery. Diversion stoma surgery temporarily transfers feces from a temporary stoma to the outside of the body and places it in a stoma bag. Diversion stoma surgery also has certain risks, and many complications are likely to occur during the surgery and subsequent nursing process, and the stoma bag will also have an adverse impact on the quality of life of patients.

At the end of the intestinal sleeve negative pressure tube 4 in the area of the elastic stent 1, it is a blind hole, and a plurality of ventilation holes are arranged on the outer side wall. The other end of the intestinal sleeve negative pressure tube 4 is connected to a negative pressure generating device. Under the negative pressure action of the negative pressure generating device, the intestinal sleeve 2 can be adsorbed on the inner wall of the elastic stent 1.

[0028] Furthermore, a biological coating film 11 is covered on the outer wall of the elastic stent 1 to reduce the burden on the intestine and reduce the friction on it.

[0029] To achieve good fixation of the elastic stent 1 to the intestine, a plurality of fixing rings 3 are arranged on the outer wall of the elastic stent 1.

[0030] The fixing ring 3 is an inflatable ring-shaped structure, arranged on the outer wall of the elastic stent 1, and is connected to the fixing ring inflatable tube 5. The fixing ring inflatable tube 5 is arranged between the intestinal sleeve 2 and the elastic stent 1, and one end extends out of the elastic stent 1 and extends a certain distance to the outside of the body and is connected to a gas supply device. It can be inflated under the gas supply action of the gas supply device to achieve good fixation of the elastic stent 1 to the intestine. In the attached Figure 1 drawing, there are two fixing rings 3, which are respectively arranged at both ends of the elastic stent 1.

[0033] As shown in the appendix Figure 1 , 4 shown, the fixing ring 3 and the intestinal cannula 2 are well fixed to the elastic bracket 1 through non-absorbable wires, specifically nylon sutures and polypropylene sutures. The intestinal cannula negative pressure tube 4 and the fixing ring inflatable tube 5 are arranged in the gap between the intestinal cannula 2 and the elastic bracket 1 to avoid interference during the implantation process.

[0034] Furthermore, to achieve good fixation between the intestinal cannula 2 and the elastic bracket 1 and at the same time reduce feces and the like from entering the gap between the elastic bracket 1 and the intestine, as shown in the appendix Figure 5 shown, the end of the intestinal cannula 2, specifically the proximal end, is fixedly connected to a fixing ring 3, that is, the proximal end fixing ring 31. The connection can be realized by bonding or ultrasonic welding. The fixing ring 3 is arranged at the end of the elastic bracket 1. Specifically, the fixing ring 3 can be connected to the elastic bracket 1 through non-absorbable wires. The elastic bracket 1 is arranged between the fixing ring 3 and the intestinal cannula 2.
