1. A multipurpose laser pointing-equipment for medical use comprising:
a pointer assembly lifted from a floor and emitting downward a laser beam for marking a reference for a surgical part on the body of a patient and for measuring a surgical range;
a standing base being a basis for supporting the equipment in an erect position;
a positioning supporter being erect on the standing base to lift the pointer assembly and adjust a height, a position, and an angle of the pointer assembly; and
a controller disposed at a position for a user to operate the equipment,
wherein,
the pointer assembly includes:
an assembly housing being a main body of a combination of components;
a guide pointer disposed in the assembly housing and emitting a laser beam for marking a reference for a surgical part;
a first marking pointer disposed in the assembly housing and emitting a first laser beam for measuring the surgical range;
a second marking pointer disposed in the assembly housing emitting a second laser beam adjacent the first laser beam for increasing the surgical range; and
a driving unit for adjusting angles of the guide pointer, adjusting angles of the first and second marking pointers, and adjusting a position of the second marking pointer,
the assembly housing further comprises an extension rod longitudinally reciprocating from at least one side to adjust the position of the second marking pointer;
the guide pointer comprises:
a vertical pointer emitting a laser beam to the surgical target to indicate a center of the surgical target, and at least one or more angle pointers spaced apart from each other at both sides of the vertical pointer and emitting a laser beam to the surgical target to indicate an insertion angle of an operation instrument or an operation implant prosthesis; and
the vertical pointer and the angle pointers are laser pointers emitting a laser beam in a spot shape onto an emission target, and
the driving unit comprises:
a first driving motor and a first power transmission member that rotate the angle pointers in the assembly housing to adjust emission angles of the laser beams emitted from the angle pointers;
a second driving motor and a second power transmission member that rotate the first marking pointer in the assembly housing to adjust an emission angle of the laser beam emitted from the first marking pointer;
a third driving motor and a third power transmission member that rotate the second marking pointer in the extension rod to adjust an emission angle of the laser beam emitted from the second marking pointer;
a fourth driving motor and a fourth power transmission member that reciprocate the extension rod longitudinally from at least one side in the assembly housing to adjust a position of the second marking pointer; and
a guide member that guides reciprocation of the extension rod in cooperation with the assembly housing and the extension rod.
