Magnetic device used for cardia-esophagogastric varices sugiura

Abstract

The invention relates to a magnetic device used for cardia-esophagogastric varices sugiura. The device comprises two permanent magnet conduit groups of the same structure and with inverse magnetic poles, wherein permanent magnets are positioned in the pipe cavities of the conduits; a non magnetic plastic sheet is arranged between every two magnets; two permanent magnet conduit groups with the corresponding size and shape are adopted to block the cardia-esophagogastric varices in a squeezing mode, so as to avoid the defects of large trauma and multiple complications of laparotomy; side holes on conduit walls can drain enterocoelia exudate, reduce the abdominal pressure and prompt the function recovering of an enterocoelia visceral organ; and in addition, the vein blocking-up can be carried out repeatedly by stages, thus portal hypertension stomach illness caused by excessive sugiura can be avoided, and the part of the conduit remained in vitro can be directly pulled out, thus the foreign matter can not be reminded in vivo.

Description

technical field [0001] The invention relates to a medical device, in particular to a magnetic device for disconnection of cardia-gastric varicose veins. Background technique [0002] At present, the devascularization of cardia-gastric varices is mainly to ligate the bleeding collateral circulation between the portal vein and the systemic vein after surgery to achieve the purpose of preventing bleeding. Extensive bleeding during the operation or secondary hemorrhage due to the slippage of the ligature after the operation, plus the foreign body reaction caused by the retention of the ligature silk in the body, aggravated the injury of the patient's body; Repeat laparotomy, and the incidence of rebleeding is high due to gastric ischemia and gastric mucosal lesions after relaparotomy, and more than 70% of cases of death are caused by rebleeding. Adhesions, coupled with the non-drainage approach and the local granulation tissue reaction and hyperplasia caused by the ligature, in...

AI Technical Summary

Problems solved by technology

[0002] At present, the devascularization of cardia-gastric varices is mainly to ligate the bleeding collateral circulation between the portal vein and the systemic vein with silk thread after surgical cut-off, so as to achieve the purpose of preventing bleeding. Extensive blood oozing during the operation or secondary hemorrhage due to slippage of the ligature after the operation, coupled with the foreign body reaction caused by the retention of the ligature silk thread in the body, aggravated the injury of the patient's body; Repeat laparotomy, and the incidence of rebleeding is high due to gastric ischemia and gastric mucosal lesions after relaparotomy, and more than 70% of cases of death are caused by rebleeding. Adhesions, coupled with the non-drainage approach and the local granulation tissue reaction and hyperplasia caused by the ligature, increase the difficulty of reoperation, and cause the formation of a large amount of ascites, which leads to increased intra-abdominal pressure, thereby compressing the abdominal organs and causing visceral damage. Occurrence of complications with decreased blood supply and venous return

The shortcoming of this silk thread as a cardiac-fundal variceal devascularization device seriously affects the long-term efficacy, but there is no device specifically for cardiac-fundal variceal devascularization except the silk thread
