  • Publication number: 20250069421
    Abstract: The present disclosure provides a cell segmentation and typing method, device, apparatus and medium based on machine learning. The method includes: acquiring at least one cell metabolism image of a target object; performing single cell image segmentation on the at least one cell metabolism image by using a machine learning segmentation model to obtain a plurality of single cell metabolism images; performing single cell feature extraction on each single cell metabolism image of the plurality of single cell metabolism images to obtain a single cell image feature map corresponding to the single cell metabolism image; combining the single cell image feature map corresponding to each single cell metabolism image of the plurality of single cell metabolism images to obtain an image feature map of the target object; performing typing of the cell by clustering the image feature map of the target object.

  • Patent number: 12042144
    Abstract: The present teaching relates to a reset apparatus including a first transmission mechanism, a first rotary transmission mechanism, a one-way rotary transmission mechanism, and a second rotary transmission mechanism; a stapler; and a medical device. The one-way rotary transmission mechanism only rotates in a set direction, and is connected with the second rotary transmission mechanism, and drives the same to rotate towards the set direction. In a first state, the first transmission mechanism is connected with the first rotary transmission mechanism which drives the first transmission mechanism to act along the set direction. In a second state, the first transmission mechanism is connected with the second rotary transmission mechanism which drives the first transmission mechanism to act along the set direction. The present invention achieves manual resetting when the device is accidentally shut down, and is simple in structure, and safe and reliable in use.
