Choledochoscope for minimally invasive surgery robot

A choledochoscope for a minimally invasive surgery robot is controlled by the minimally invasive surgery robot to achieve examination and treatment in hepatic ducts. The choledochoscope for the minimally invasive surgery robot comprises a choledochoscope body and accessory equipment. The choledochoscope body comprises a front end assembly, a bent assembly, a rigid connecting rod and a choledochoscope box, wherein one end of the bent assembly is fixedly connected to the front end assembly, and the other end of the bent assembly is fixedly connected to the rigid connecting rod; the other end of the rigid connecting rod is rotatably installed on the choledochoscope box; the bent assembly achieves bent movement in one direction; spin motion of the rigid connecting rod of the choledochoscope body is achieved between the rigid connecting rod and the choledochoscope box; the choledochoscope box is mainly used for enabling the choledochoscope body to be fixedly connected with the minimally invasive surgery robot and transmitting driving force for controlling other assemblies of the choledochoscope to move. The choledochoscope for the minimally invasive surgery robot has the advantages of improving the success rate of surgery, relieving the fatigue of doctors, having enough flexibility, shortening surgery time and reducing calculus removal difficulty, thereby having the potential of being applied to the other medical fields.
