Porta hepatis blocker

Abstract

The invention discloses a porta hepatis blocker, and relates to the technical field of medical apparatuses. The porta hepatis blocker comprises a gun body, a displayer, a handle, a connecting rod, a button, a sliding strip, a sliding groove, a probe, a connecting hole, a connector and a medical wire, wherein a through groove which is matched with the probe is horizontally formed in the connectingrod; the probe is in electric data connection with the displayer; a plurality of first balls and a plurality of second balls which are rotatably connected are arranged at one end of the inner part ofthe connecting rod, and a plurality of third balls and a plurality of fourth balls which are rotatably connected are arranged at the other end of the inner part of the connecting rod; and the first balls and the third balls are arranged at the top of the through groove, and the second balls and the fourth balls are arranged at the bottom of the through groove. According to the porta hepatis blocker disclosed by the invention, a blood vessel requiring blocking can be quickly tied by the medical wire; through adjusting the position of the button, the tightness degree of tying is regulated, so that the position of the blood vessel is convenient to examine; and rolling auxiliary can be performed on two ends of the through groove, so that the probe part in the through groove can be always in astraight line state, and the stability of the probe can be strengthened.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and more specifically, the invention relates to a hepatic portal blocker. Background technique [0002] In hepatobiliary surgery, hepatic portal occlusion devices are often used. Hepatic portal occlusion includes hepatic blood flow occlusion, hepatic blood flow occlusion, and hepatic vein occlusion. Local resection of liver lesions, or resection of regular hepatic segments and lobes, can reduce liver bleeding, minimize the risk of intraoperative surgery and the incidence of postoperative liver failure. [0003] However, the existing porta hepatic blocking device sometimes cannot directly view the position of the blood vessel due to various reasons such as the patient himself and the position of the incision, which causes unnecessary trouble to the operation. Contents of the invention [0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the pr...
