According to a further feature of the cassette for intraoperative placement of steep pulse ablation probes of the present invention, the first grooves are located and numbered corresponding to the third grooves.
According to the further characteristic of the box for placing the steep pulse ablation probe in the operation, the upper surface of the box cover is provided with the circular convex body, so that the box cover is pushed and pulled, and the box body is opened and closed.
According to the further characteristics of the box for placing the steep pulse ablation probe in the operation, a plurality of round supporting bodies are arranged on the bottom surface of the box body, so that the friction force of the bottom of the box is increased, and the aim of preventing slipping is fulfilled.
Compared with the commonly used sterile surgical towel, the box for placing the steep pulse ablation probe in the operation has the following beneficial effects: (1) the box is closed and matched with the probe in size, and the probe is placed in the box to move, so that the situation that the probe accidentally falls off due to the dragging of a connecting wire and the like can be effectively avoided; (2) the box is hard and cannot be punctured, and the occurrence of needle stick injuries can be effectively avoided.
