Embodiment 1
[0029] Such as figure 1 As shown, the remote-controlled hepatic portal blocking system of the present invention includes a radio frequency remote controller 1 and a liver portal blocking device 2;
[0030] The radio frequency remote controller 1 includes a radio frequency control module 102 and a radio frequency transmission module 101;
[0031] The output end of the radio frequency control module 102 is connected to the input end of the radio frequency transmission module 101;
[0032] The radio frequency control module 102 is preset with a remote control blocking command and a remote control unblocking command. Correspondingly, the radio frequency control module 102 includes two physical keys or touch buttons, one of which is used to send a remote control blocking command, and the other Physical buttons or touch buttons are used to send remote control dredging instructions; the radio frequency control module 102 can be set in mobile terminals or desktop devices;
[0033] T...

The invention discloses a hepatic portal occlusion system with remote control. The hepatic portal occlusion system comprises a radio-frequency remote controller and a hepatic portal occluder, whereinthe radio-frequency remote controller is connected to the hepatic portal occluder in a wireless manner; the radio-frequency remote controller sends a remote-control occlusion instruction and a remote-control dredge instruction to the hepatic portal occluder in turns; when the radio-frequency remote controller sends the remote-control occlusion instruction to the hepatic portal occluder, the hepatic portal occluder occludes the hepatic portal; when the radio-frequency remote controller sends the remote-control dredge instruction to the hepatic portal occluder, the hepatic portal occluder dredges the hepatic portal. The hepatic portal occlusion system with remote control disclosed by the invention has the beneficial effects that the hepatic portal occlusion or dredge instruction is remotelycontrolled by the radio-frequency transmitting module and the radio-frequency receiving module and further the hepatic portal occlusion mechanism is operated 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 the liver operation are greatly reduced.
Description
technical field [0001] The invention relates to a remote-controlled hepatic portal blocking system, 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...
