DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 3A surgical expansion structure includes a first expansion plate 1 and a second expansion plate 2. The top of the first expansion plate 1 is rotatably connected to two guide columns 3. The first expansion plate 1 and the second expansion plate 2 are inserted into the wound, and then the first expansion plate 1 and the second expansion plate 2 are pulled to move, so as to expand the wound. The outer wall of the guide column 3 is provided with a plurality of slots 4. The top of the second expansion plate 2 is fixed with two guide plates 5 by bolts. The guide plates 5 are in contact with the guide columns 3. The top of the second expansion plate 2 is fixed with two adjustment boxes 6 by bolts. The top of the adjustment box 6 is provided with a groove 7. The adjustment box 6 is rotated inwardly. The guide column 3 is movably connected with a toggle block 8, and the outer wall of the toggle block 8 is sleeved with a torsion spring 10. The outer wall of the toggle block 8 is fixedly sleeved with a claw 9, and the claw 9 is engaged with the slot 4. Under the action of the torsion spring 10, the claw 9 is engaged with the slot 4, so that the distance between the first expansion plate 1 and the second expansion plate 2 is fixed. The outer wall sliding sleeve of the guide column 3 is provided with a first sliding sleeve 12, and the top outer wall of the first sliding sleeve 12 is welded with a second sliding sleeve 14. A separation rod 15 is slidably inserted in the second sliding sleeve 14, and the first sliding sleeve 12 is pulled to slide on the guide column 3 to adjust the position of the separation rod 15.

[0022] The first expansion plate 1 and the second expansion plate 2 are both L-shaped structures. The tops of the first expansion plate 1 and the second expansion plate 2 are fixed with pull rod handles 11 by bolts. The outer walls of the pull rod handles 11 are sleeved with anti-slip sleeves, so as to facilitate the operation of the first expansion plate 1 and the second expansion plate 2. The bottom thread of the first sliding sleeve 12 is inserted with the first tightening screw 13, and the first sliding sleeve 12 is fixed by tightening the first tightening screw 13.
