Inferior vena cava root vascular anatomical dissecting forceps for liver surgery

Abstract

The invention discloses an inferior vena cava root vascular anatomical dissecting forceps for liver surgery. The dissecting forceps comprises a forceps body, two forceps handles and a forceps head, wherein the forceps body is a cylinder; the inside of the cylinder is a cavity structure; and the two forceps handles are connected to the rear end of the forceps body and are symmetrically distributedabout the forceps body. The dissecting forceps drives a pull rod to rotate and stretch by a driving structure so as to open and close the forceps head and rotate the forceps head, and to adjust the angle of the forceps head. During inferior vena cava root vascular dissection, a surgeon can operate without twisting his / her wrist, improves operation precision, and avoids a danger caused by twistingthe wrist. The inferior vena cava root vascular anatomical dissecting forceps is convenient to use.

Description

technical field [0001] The invention relates to the field of surgical medical instruments and equipment, in particular to an anatomical separation forceps for blood vessels at the root of the inferior vena cava for liver surgery. Background technique [0002] During liver surgery, it is often necessary to separate and ligate one or two hepatic veins to cut off the blood flow out of the liver in this area. At present, there is no special forceps for separating blood vessels at the root of the vena cava clinically, and large-scale thoracic forceps or Replacing with right-angle vascular forceps, due to the particularity and importance of the anatomical position of the root of the inferior vena cava, the above alternative instruments are not satisfactory in terms of the convenience and safety of the operator's operation, and are not convenient for medical staff to hold and operate And reset after operation, under the condition that guarantees that medical staff's wrist does not ...
