SURGICAL INSTRUMENTS, ROBOT ARM AND ROBOT ARM ASSEMBLY USING THE SAME

摘要

The present invention relates to surgical instruments, a robot arm, and a robot arm assembly using the same. The surgical instruments comprise a housing (10) in which a guide (12) is formed; multiple driving pulleys respectively forming key blocks (22) combined on the housing (10) and arranged side by side along the longitudinal direction of the housing (10) on one surface exposed to the outside; a shaft (30) communicated and installed with the housing (10); an end effector (40) combined on a front end of the shaft (30); and a wire (50) in which on side is wound on the driving pulley (20) and the other side is connected with the end effector (40) through the shaft (30). Also, the robot arm comprises a casing (60) forming a slider (62); a rotation member (70) combined on the casing (60); and multiple rotation plates (80) installed on the rotation member (70) where a key groove (82) is respectively formed side by side along the longitudinal direction of the casing (60) on one surface exposed to the outside. And the technical feature of the robot arm assembly is one in which the surgical instruments according to the present invention are combined to be removable on the robot arm according to the present invention. Accordingly, the surgical instruments can be easily and effectively combined to a surgical robot and used.
