An intelligent puncture path planning method, a device, an equipment and a medium in a PVP operation. The method includes: intercepting a local CT image of a vertebral body from an image; identifying midpoint of the narrowest part of vertebral pedicle and a theoretical puncture injection stop-point from the local CT image through trained neural network model; calculating distance from the stop-point to the middle plane in front-back direction of the vertebral body, distance from the stop-point to the middle plane in left-right direction of the vertebral body and the closest distance from the stop-point to the cortical bone surface, taking the minimum value of distances as radius of a space sphere area with the stop-point as sphere center; taking a line connecting midpoint of the narrowest part of any vertebral pedicle and any point in the space sphere area as an optional puncture path of the vertebral pedicle.

Disclosed is an in-vivo micro-robot for nerve stretching, comprising a channel, and a movable part and a fixed part located at the channel. The movable part is disposed to be movable along the channel, the movable part sleeves the fixed part and is used for driving the fixed part to move along the channel, and the fixed part is connected to a nerve to be stretched. The in-vivo micro-robot is embedded into a patient's body through surgery, so that the extension of the nerve is accelerated and is regular and quantitative, thereby effectively solving the problems of small probability of nerve self-repair and long recovery period in traditional nerve bridging surgery.
