Abstract

The invention discloses an ultrasound knife control device and a minimally invasive surgery robot. The minimally invasive surgery robot comprises an opening and closing drive portion, a rotating drive portion, an energy conversion portion, a lead screw, a bushing and a guide rod, wherein the busing sleeves the lead screw; the opening and closing drive portion controls the opening and closing angle of a knife head of an ultrasound knife; the rotating drive portion drives the knife head of the ultrasound knife to rotate around the axial extension line of the bushing; an energy converter in the energy conversion portion transfers energy to the knife head of the ultrasound knife through the guide rod and the lead screw. The technical problem that the control device for the ultrasound knife of the minimally invasive surgery robot in the prior art is poor in flexibility in controlling the ultrasound knife is solved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a control device for an ultrasonic knife and a minimally invasive surgical robot. Background technique [0002] In minimally invasive surgery, doctors often need to manually cut, strip, and suture tissues. The application of ultrasound is usually to convert or transmit ultrasonic energy into biological tissues through surgical equipment to produce physiological effects, especially to use the generated heat to The tissue is cauterized to stop bleeding or cut. In the ultrasonic knife of surgical instruments, the generator generates high-frequency electric energy, and the transducer uses piezoelectric materials or electromagnetically compressed materials to convert high-frequency energy into mechanical vibrations, and amplifies the vibrations and transmits them to the end effector. [0003] The ultrasonic scalpel currently on the market needs to be operated by the docto...
