LASER BEAM LEADING APPARATUS FOR PUNCTURE

摘要

A laser beam leading apparatus for puncture comprises a laser light emitter (30), which is rotatablely arranged on a base plate (10), the laser light emitter can produce laser beam that parallels to the base plate. A first angle indicator (40) used for showing the rotation angle of the laser light emitter (30) is arranged on the base plate (10). Furthermore there is a mounting plate (20) on the back of the base plate, said mounting plate (20) is hinged on the base plate (10) by a horizontal rotating axle (12). Adjusting the base plate flat is by a manner of rotation until it is parallel to the insertion plane that defined by the scanner. There is a second angle indicator (50) on the side base plate (13) J or showing the rotation angle of the base plate (10). The leading apparatus is simple in structure and easy to handle. The tridimensional parameter is determined by the rotation angles of the laser light emitter (30) and the base plate (10) defined by the two angle indicators, and the insertion plane confirmed by the aiding of the CT scanner. The whole puncture process is led by laser beam, so the puncture and insertion can be carried out accurately.
