[0002] China is gradually entering an aging society, and with the development of urbanization across the country, the risk of cardiovascular and cerebrovascular diseases is increasing. The rising incidence of these diseases has also increased the demand for interventional vascular surgery, a treatment option, leading to a year-on-year increase in related research.
[0003] In recent years, with the rapid development of robotics technology, many institutions both domestically and internationally have developed surgical robots to assist surgeons in their operations, which have great potential for clinical application. However, in numerous studies on surgical robots, most research only investigated the rotation of the guidewire.

The first drive wheel 313 abuts against the rotating wheel 2, and the rotating wheel 2 rotates due to friction. The rotating wheel 2 drives the handle 8 to rotate due to friction.
[0055] While the first transmission mechanism 3 drives the rotating wheel 2 to rotate, the second drive motor drives the second input shaft 601 to rotate.

The first pulley 608 and the second pulley 610 are driven by a belt. The second pulley drives the seventh drive shaft 609 to rotate. The seventh drive shaft 609 drives the seventh bevel gear 611 to rotate. The seventh bevel gear 611 drives the eighth bevel gear 613 to rotate. The eighth bevel gear 613 drives the eighth drive shaft 612 to rotate. The eighth drive shaft 612 drives the second drive wheel 614 to rotate. The second drive wheel 614 causes the catheter to bend by contacting the friction part 801. The bending direction of the catheter and the guide wire inside the catheter is adjusted by the rotating wheel 2 after rotation.
[0056] In this embodiment, the catheter rotation mechanism is easily and conveniently mounted on the housing 1 by using an electromagnet and a connecting mechanism. This device can be used as a disposable consumable to avoid contamination of the catheter drive mechanism by the robot's main body, improve the hygienic environment during surgery, increase the safety factor in the operating room, improve the success rate of surgery, reduce the postoperative infection rate, and protect the patient's life.
