Embodiment Construction

[0031] In order to better understand the above technical solutions of the present invention, a further detailed description will be given below in conjunction with the drawings and embodiments.

[0032] An embodiment of the degradable anti-reflux esophagogastric anastomosis bracket of the present invention is as follows: figure 1 As shown, it includes a tubular stent body 1 made of degradable material, see figure 2 . Inside the main body 1 of the tubular stent, there is an anti-reflux device 2 that can isolate the contents of the esophagus and stomach from the anastomosis, see figure 2 and image 3 . The stent for esophagogastric anastomosis of the present invention is equipped with a detachable inner core 4 passing through the inner hole of the tubular stent main body 1; the esophageal end 41 of the detachable inner core 4 is semi-ellipsoidal and protrudes from the inner hole of the tubular stent main body 1; The stomach end 42 of the detachable inner core 4 is conical...

Abstract

The invention relates to a degradable backflow-prevention esophagastro anastomosis support, relates to a hollow or tubular prosthesis capable of being implanted in vivo, and particularly relates to a degradable backflow-prevention support used for esophagastro anastomosis. The degradable backflow-prevention esophagastro anastomosis support comprises a tubular support body made of a degradable material; and a backflow-prevention device capable of isolating objects contained in an esophagastro and an anastomosis opening is arranged inside the tubular support body. The esophagastro anastomosis support is provided with a detachable inner core penetrating an inner hole of the tubular support body; the esophagus end of the detachable inner core is hemi-ellipsoidal and extends out from the inner hole of the tubular support body; the stomach end of the detachable inner core is conic; grooves capable of being clamped through vessel clamps are formed in the two sides; and annular sunken ligation grooves are formed in the surface of the periphery of the tubular support body. In an esophagastro anastomosis operation, the detachable inner core can be used for clamping operation, and depending on the supporting function of the support body and the positioning function of the ligation grooves, the operation is convenient, simple and rapid; and the support is not high in material price, the manufacturing process is simple, the operation cost can be obviously reduced, and the loads of a patient are reduced.

Description

technical field [0001] The invention relates to a hollow or tubular prosthesis that can be implanted in the body, in particular to a degradable anti-reflux bracket for esophagogastric anastomosis. Background technique [0002] Esophageal cancer is one of the most common tumors, and surgery is the preferred treatment method. The key part of esophageal cancer surgery is the esophagus-gastric anastomosis, which is also the most prone to complications. At present, the anastomosis technique mainly includes: manual suture anastomosis and stapler anastomosis. Manual suture anastomosis is a traditional anastomosis method, which is completed by manual suture with silk thread or absorbable thread. The operation is complicated and cumbersome, the anastomosis takes a long time, and there are many complications. The cost is low, and it is still the main matching method in some economically underdeveloped areas. The stapler anastomosis method is a technique that uses a stapler to comple...
