Problems solved by technology

Because the ultrasonic suction knife system is mainly aimed at tissues with high water content and softness, it can crush and remove tumor tissue or normal soft tissue without damaging vascular tissue to a certain extent. However, when the ultrasonic action time is long or the output energy is large, tiny blood vessels are also damaged

Abstract

The invention discloses a surgical system, an ultrasonic suction knife system and a control method thereof, and the method comprises the steps: obtaining the imaging data of a target tissue to be removed and the imaging data of a blood vessel, constructing a three-dimensional model of the target tissue to be removed and the blood vessel to be removed, carrying out the overlapping positioning of the three-dimensional model and the positioning data of a to-be-operated part, determining the positioning data of the blood vessel, according to the positioning data of the blood vessel and the positioning data of the ultrasonic suction knife, the relative positions of the ultrasonic suction knife, determining the target tissue and the blood vessel, that is, the relative positions of the ultrasonic suction knife and the blood vessel are positioned, and obtaining the corresponding control parameters according to the relative positions in combination with the diameter of the blood vessel. The control parameters are determined according to the relative position of the ultrasonic suction knife and the blood vessel and the diameter of the blood vessel, so that the blood vessel can be prevented from being damaged while the tumor is removed.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an operation system, an ultrasonic suction knife system and a control method thereof. Background technique [0002] The ultrasonic suction knife system is mainly used in tumor removal surgery, which utilizes the cavitation effect and mechanical effect of ultrasound to pulverize and remove tumor tissue or normal tissue. Because the ultrasonic suction knife system is mainly aimed at tissues with high water content and softness, it can crush and remove tumor tissue or normal soft tissue without damaging vascular tissue to a certain extent. However, when the ultrasonic action time is long or the output energy is large, Tiny blood vessels are also damaged. In tumor resection, it is often necessary to adjust the ultrasonic parameters output by the ultrasonic suction knife system to avoid damage to the blood vessels. However, some brain tumors have rich blood supply, and the thickness of...
