Embodiment 1

[0062] A kind of anti-fistula device for anastomotic stoma in this embodiment, such as figure 1 shown, which includes:

[0063] A stent braid 1, the stent braid 1 is a fully degradable material, and is braided and shaped by a wire. And has a self-expanding mesh structure to provide continuous circumferential support to the intestinal wall. Such as figure 1 As shown, the stent braid 1 is a columnar structure with a diameter at the middle position smaller than that at both ends; the middle position of the stent braid 1 is the contraction part 2; as figure 2 As shown, one end of the stent braid 1 is an inlet reaming part 3 used to fit the inner folds of the intestinal tract, and the inlet reaming part 3 allows solids and liquids in the intestinal tract to enter the anastomotic anti-fistula device to protect the Intestinal wound lateral to constriction 2; eg image 3 As shown, the other end of the stent braid 1 is an outlet reaming portion 4, which is used for the outflow of ...

Embodiment 2

[0071] A sealed storage box is used for storing an anastomotic stoma anti-fistula device, and the anastomotic stoma anti-fistula device is in a released state in the sealed storage box. The above-mentioned sealed storage box can effectively seal and store the anastomotic stoma anti-fistula device to protect the fully degraded polymer metal material. Moreover, the sealed storage box is in a released state when storing the anastomotic stoma anti-fistula device, which is used to avoid material creep and stress relaxation caused by long-term pressing.

Embodiment 3

[0073] Such as Figure 4 As shown, the loader 6 includes: a connecting tube 7 and a loading funnel 8 arranged at the end of the connecting tube 7, the anastomotic stoma anti-fistula device is accommodated in the connecting tube 7; and, the outlet The reaming part 4 is provided with a traction rope 9 for loading the anastomotic stoma anti-fistula device.

[0074] The use method of the above-mentioned loader 6 is as follows: the traction rope 9 is passed through the loading funnel 8 and passed out from the connecting pipe 7, so that the anastomotic stoma anti-fistula device is pulled by the traction rope 9, so that the anastomotic stoma anti-fistula device Through the loading funnel 8 , the crimping is loaded into the connecting pipe 7 . The connecting tube 7 is nested with the delivery system, so that the device is put into the delivery system, and the traction rope 9 is cut off and taken away after the anastomotic stoma anti-fistula device is loaded.

Abstract

The invention relates to the technical field of medical equipment, in particular to an anastomotic stoma fistula prevention device, a sealed storage box and a loader. The anastomotic stoma fistula prevention device comprises a stent woven body which is made of a fully degradable material and is of a net-shaped structure with self-expansion performance so as to provide continuous circumferential support for the inner wall of the intestinal tract; a covering film covering the surface of the stent woven body so as to cover the meshes in the stent woven body; and a covering film is made of a fully degradable material. The stent woven body is made of a full-degradable material with self-expansion performance, and a covering film used for covering the surface of the stent woven body is also made of a full-degradable material. Therefore, the problems that an existing large intestine fistula prevention device needs to be taken back, the operation complexity degree is improved, and meanwhile the pain of a patient is increased are solved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an anastomotic stoma anti-fistula device, a sealed storage box and a loader. Background technique [0002] At present, in the field of anorectal surgery, the method of preventing large bowel fistula, in addition to sufficient intestinal preparation before operation, is to perform ileum or transverse colostomy is currently recognized worldwide as an effective and reliable method to prevent and treat large bowel anastomotic leakage. [0003] In the prior art, for example, the patent document whose publication number is CN2875327Y discloses: a large intestine anti-fistula device. The above-mentioned large intestine anti-fistula device cannot be completely degraded after the operation is performed. As a result, the anti-fistula device for the large intestine needs medical workers to perform an operation again to retrieve the anti-fistula device for the large intestine. Th...
