Abstract

A laser tourniquet. A metal tourniquet (1) is installed at the end portion of a laser fiber. The metal tourniquet is installed on the fiber (3) through a fastener (2) or heat-shrinkable tubing. The metal tourniquet comprises a spherical head. The metal spherical head can convert laser energy into thermal energy, and the metal spherical head directly contacts and presses bleeding tissue to achieve a bleeding control function, thereby avoiding disadvantages in earlier laser bleeding control such as a small action area, difficulties in finding the position of an optimal action point and in selecting an action direction of laser accurately, and lack of compressed action on the target tissue. It is proved through many times of test that the tourniquet has a desirable effect in bleeding control and is convenient to use.
