Abstract

The invention relates to the field of medical instruments, and discloses a multi-degree-of-freedom instrument assembly of a single-hole surgical robot, comprising: a catheter; , the second rigid pipeline, the second flexible pipeline, and the surgical instrument; the first rigid pipeline is penetrated in the catheter, the first rigid pipeline and the second rigid pipeline are provided with hollow channels, and the first flexible pipeline and the second flexible pipeline are provided with hollow channels. The pipeline is provided with a number of partitions, the partitions are provided with a number of through holes, the hollow channel and the through holes are provided with steel wires; the spreading mechanism includes a main push rod and a number of support rods. The single-hole surgical robot multi-degree-of-freedom instrument assembly of the present invention only needs to pass through one opening to insert a variety of surgical instruments without opening multiple openings, which will greatly reduce the surgical trauma and the volume of the equipment, and the operations of each surgical instrument are independent of each other. Precise and reliable.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a multi-degree-of-freedom instrument assembly of a single-hole surgical robot. Background technique [0002] Surgical robots are used for the treatment of various surgical diseases, but in the implementation process, 3-5 holes need to be opened in the abdomen for the entry of surgical instruments. It not only increases trauma, but also leaves scars for patients after surgery, and the cosmetic effect is poor. With the use of a single-port surgical robot, it was shown to have the same effect as a multi-port surgical robot. However, the control technology of the surgical instruments at the end of the existing single-hole surgical robot is still immature, and the independence and sensitivity of the surgical instruments need to be improved. SUMMARY OF THE INVENTION [0003] Aiming at the technical problems of low independence and low sensitivity in the control of the surgical in...
