Disclosed are an automatic planning method and a device for tissue ablation. The method includes: obtaining a three dimensional (3D) model of a to-be-ablated tissue through a 3D reconstruction technique; marking a cylindrical ablation point on the 3D model through an ablation planning, an axial direction of the ablation point is the same as a radio frequency direction of thermal ablation; and displaying an ablated area on the 3D model, the reconstruction technique includes: obtaining slice images of the to-be-ablated tissue in a plurality of directions, the slice image in each direction includes a plurality of two dimensional (2D) images; depicting, by a primitive, the to-be-ablated tissue on the 2D images in one direction; and constructing the 3D model of the to-be-ablated tissue through the 3D reconstruction technique based on the original 2D images.

Automatic planning method and device for tissue ablation

A distributor (), a falling film evaporator and a refrigerating system. The distributor includes: a sprayer (), the top of the sprayer being connected to a falling film evaporator inlet (), and the bottom of the sprayer being provided with spray holes (); and an orifice plate () disposed at a lower end of the sprayer and provided with multiple distribution holes (), wherein a centrifugal gas-liquid separating element is disposed in the sprayer and is configured to separate a refrigerant entering the sprayer through the evaporator inlet into a gas phase and a liquid phase. In the distributor, the centrifugal gas-liquid separating element is disposed in the sprayer, so that a two-phase refrigerant entering the sprayer through the evaporator inlet can be better separated under dual effects of the gravity and the centrifugal force.
