Visual retrohepatic tunnel separation haemostatic forceps with adjustable angles

Abstract

The invention discloses visual retrohepatic tunnel separation haemostatic forceps with adjustable angles. The forceps comprise two rod body sections movably connected, a camera installed on one rod body section, a forceps part mechanism installed on one rod body section, a forceps handle mechanism used for controlling the motion of the forceps part mechanism andinstalled on the other rod body section and an angle adjusting mechanism installed between two rod bodies; the angle adjusting mechanism comprises a rotary knob provided with a threaded hole androtatably connected with the rod body section close to the forceps handle mechanism, and a rack plate slidablyconnected to the inside of the rod body section and meshed with the rotary knob with the threaded hole. According to the forceps, existing separation haemostatic forceps used for liver operations are improved, the visual retrohepatic tunnel separation haemostatic forceps have the advantages that the haemostatic forceps head can extend into the retrohepatic tunnel and adjust angles, and visual separation hemostasis is achieved, the operation difficulty of liver operations is greatly reduced, and the success rate of the operations is increased so that young doctors lack of the experience of liver operations can treat patients better.

Description

technical field [0001] The invention relates to the technical field of hepatic hemostats, in particular to a hemostatic forceps with adjustable angle and visualized retrohepatic tunnel separation. Background technique [0002] The retrohepatic tunnel refers to a potential gap with relatively few blood vessels between the inferior vena cava in the posterior segment of the liver and the liver parenchyma. Fissure anterior to the vena cava. The Belghiti liver lifting technique is to use hemostats to separate from the lower edge of the caudate lobe of the liver to the second hepatic porta to establish a retrohepatic tunnel; use hemostats to pull the vascular blocking band through the tunnel, pull the band around the liver and keep it With a certain tension, the liver is separated from the retrohepatic inferior vena cava, and the liver parenchyma is incised under the guidance of the liver belt for liver resection. However, the method of pulling around the liver cannot establish ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a visual hemostatic forceps with adjustable angle for visual retrohepatic tunnel separation, which has the advantage of being able to adjust the angle when the hemostatic forceps head is inserted into the posterior hepatic tunnel, and solves the above-mentioned deficiencies in the background technology
