摘要： The present disclosure provides a surgical shunt assembly tool that provides a more efficacious grip on the catheter tubes and prevent the tip of the catheter from buckling while the catheter is pushed onto the tip of the valve during installation of shunts during CSF shunt surgery. The tool includes standard handles such as used in a shodded misquito tool having a clamping jaw integrated into the distal end section of the handle. The distal jaw includes two forcep jaw sections each having a proximal end integrally formed with a distal end of a distal end arm section of one of the two handle arms, and a distal end section extending away from the distal end arm section. The distal end sections of the forcep jaw sections are cylindrically shaped such that when the forcep jaw is closed by bringing the two forcep jaw sections together, a cylinder is formed having a diameter substantially equal to a diameter of a catheter tube to be attached to a shunt valve tip. The proximal ends of the forcep jaw sections are oval shaped and have a size such that when the forcep jaw is closed bringing the two forcep jaw sections together, an oval shaped opening is formed having a size smaller than the diameter of the catheter tube such that the catheter tube is squeezed closed to provide a firm grip of the tool of the catheter tube.
