Hepatic artery hemostat

Abstract

The invention relates to the field of surgical instruments, and discloses a hepatic artery hemostat which is fixed with a human body through a fixing belt and a back plate. The sliding plate slides relative to the back plate, the first rotating rod is rotationally connected with the sliding plate, the second rotating rod is rotationally connected with the sliding plate, the first rotating rod and the second rotating rod rotate along with the sliding block and can be fixed through a clamping groove and a buckle, the horizontal sliding block is in sliding connection with the first rotating rod, and the horizontal adjusting screw rod is in threaded connection with the first rotating rod; the horizontal adjusting screw rod is rotated to drive the horizontal sliding block to move for alignment; the locking rod is in threaded connection with the sliding plate, and the locking rod is rotated to fix the sliding plate; the control screw rod is in threaded connection with the horizontal sliding block, the mounting head is rotationally connected with the control screw rod, the pressing block is detachably connected with the mounting head, the control screw rod is rotated to drive the mounting head and the pressing block to be close to the hepatic artery and conduct pressing, the support is provided through the first rotating rod, the second rotating rod and the back plate, so the pressing is more stable, and the hemostatic effect is improved.

Description

technical field [0001] The invention relates to the field of surgical instruments, in particular to a hepatic artery hemostat. Background technique [0002] The hepatic artery is one of the three major branches of the celiac artery. It originates from the celiac artery as the common hepatic artery; above the first part of the duodenum, after separating the right gastric artery and the gastroduodenal artery successively, the main trunk is called the proper hepatic artery; Ascending in the duodenal ligament, most divide into left and right hepatic arteries outside the first hepatic portal, and a few divide into left, middle and right branches, entering the left and right hepatic lobes respectively. [0003] After the puncture treatment, due to the high pressure of the artery itself, it needs to be compressed for a long time to stop the bleeding. The existing binding method of the pressure plate is easy to be misplaced, resulting in a decline in the hemostatic effect. Conten...
