Hepatic portal occlusion device with remote control

Abstract

The invention discloses a hepatic portal occlusion device with remote control. The hepatic portal occlusion device comprises an upper shell and a lower shell, wherein one side of the upper shell and one side of the lower shell are movably connected together by a hinge, and the other opposite sides of the upper shell and the lower shell are clamped together in an openable-closable manner by a fastener; the upper shell and the lower shell enclose into a hepatic portal occlusion working cavity; the hepatic portal occlusion working cavity is internally provided with a miniature speed-reducing motor, a main controller, a radio-frequency receiving module and a battery module; the output end of the radio-frequency receiving module is connected to the input end of the main controller, and the control-signal output end of the main controller is connected to the driving-signal input end of the miniature speed-reducing motor; an output shaft of the miniature speed-reducing motor is connected witha gear, an occlusion belt is meshed on the gear, and one end of the occlusion belt is fixed at the outer part of the hepatic portal occlusion working cavity. The hepatic portal occlusion device withremote control disclosed by the invention has the beneficial effects that the occlusion belt can be loosened or tightened by remotely controlling the forward and reverse rotation of the miniature speed-reducing motor, so that occlusion and dredge of blood flow into the liver under a laparoscope are realized, the operation is simple and the difficulty and the risk of hepatic portal occlusion in theliver operation are greatly reduced.

Description

technical field [0001] The invention relates to a remote-controlled hepatic portal blocking device, which belongs to the technical field of medical devices. Background technique [0002] The liver is rich in blood supply. In liver surgery, in order to reduce intraoperative blood loss or avoid intraoperative hemorrhage, it is usually necessary to block the blood flow into the liver, that is, block the blood flow of the first hepatic portal (or block the hepatoduodenal ligament ). At present, there are many methods for blocking the hepatoduodenal ligament, such as the Pringle maneuver, and blocking the duodenal ligament with a pediatric catheter. However, whether it is traditional open surgery or laparoscopic liver surgery, which is more and more widely used at present, there are many problems in the application of these methods. [0003] For example, in laparoscopic surgery, the liver operation usually lasts more than one hour, and the hepatic hilum blockage time cannot exc...
