Example Embodiment
[0027] Example 1:
[0028] A device for creating a cavity by magnetic traction, which is suitable for neck endoscopic surgery. The cavity building device is composed of a magnetic device 1 arranged on the surface of the skin 2 and a support arm arranged under the skin 2 layer. The magnetic force arranged on the surface of the skin 2 The device 1 attracts the stent arm arranged under the skin 2 layer to move outward to create a surgical cavity; the stent arm is flexibly connected by the upper stent arm 3 and the lower stent arm 6 through rivets 4; the stent arm is magnetically Made of attractive materials. The magnetic device 1 is made of an electromagnet. The bracket arm is made of a metal material that can be attracted by magnetic force. The upper support arm 3 and the lower support arm 6 are provided with an elastic support sheet 5 that can be extended outwards. The upper support arm 3 and the lower support arm 6 are provided with sliding grooves for the elastic support shee...
