Problems solved by technology

[0005] But in the actual operation, if the ultrasonic scalpel acts on the tissue for too long, the heat of the tissue will be too high, causing the tissue to burn, and the closure effect will be greatly reduced

Embodiment Construction

[0019] The purpose of the present invention is to provide an ultrasonic knife, how to avoid tissue burning while maintaining the cutting speed.

[0020] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Please refer to figure 1 , figure 2 as well as image 3 , an ultrasonic scalpel control system provided by the present invention includes a host computer and an ultrasonic scalpel connected to the host computer. The host computer provides a driving signal to the ultrasonic scalpel to monitor the real-time driving voltage of the ultrasonic scalpel and the real-time phase difference of the real-time driving current, and set the ultrasonic scalpel The predetermined phase difference value corresponds to the corresponding tissue type. When the real-time phase difference val...

Abstract

The invention provides an ultrasonic knife control system which comprises a host and an ultrasonic knife connected with the host, the host provides a driving signal for the ultrasonic knife, and the ultrasonic knife control system is characterized in that the real-time phase difference value of the real-time driving voltage and the real-time driving current of the ultrasonic knife is monitored; a preset phase difference value of the ultrasonic knife is set to correspond to the corresponding tissue type, and when the real-time phase difference value is different from the preset phase difference value, the driving power of the ultrasonic knife is adjusted, so that the real-time phase difference value is close to the preset phase difference value. When a thin tissue is cut in an operation, the needed power is small, and when the real-time phase difference value monitored by the host is different from the preset phase difference value, the power can be adjusted to enable the real-time phase difference value to be close to the preset phase difference value, so that the proper output power is achieved, and the fastest cutting speed is kept while the tissue is prevented from being burnt.

Description

technical field [0001] The present disclosure generally relates to the field of medical ultrasonic surgery, and specifically relates to a control system of an ultrasonic knife. Background technique [0002] Ultrasonic surgical devices are used in a variety of applications in surgery due to their unique performance characteristics. Depending on the particular device configuration and operating parameters, ultrasonic surgical devices are capable of substantially simultaneous tissue transection and hemostasis by coagulation, thereby advantageously minimizing patient trauma. The ultrasonic surgical device includes a proximally positioned ultrasonic transducer and an instrument coupled to the ultrasonic transducer, the instrument having a distally mounted end effector including an ultrasonic knife to cut and seal tissue. The end effector is typically coupled to the handle and / or robotic surgical tool via a shaft. The blade is acoustically coupled to the transducer via a wavegui...
