Operation cutting probe and ophthalmologic operation equipment

Abstract

The invention provides an operation cutting probe and ophthalmologic operation equipment, and relates to the technical field of medical instruments, after an inner cutting piece rotates, a second cutting edge on a spiral fan blade can do relative cutting motion with a first cutting edge when passing through a notch of a cutting outer tube, so that tissue extending into the notch is cut off, and the cutting efficiency is improved. And the cut tissue enters the cutting outer tube. The suction mechanism connected with the near end of the probe can generate suction force, tissue is sucked and discharged outwards through the suction channel between the cutting outer tube and the transmission structure, further, a spiral fan blade structure is arranged, certain centrifugal force can be generated when high-speed rotating movement occurs, and therefore the suction performance is further improved, and the flow rate is increased.
