Detailed Description

The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention.

Referring to fig. 1-3, the present invention provides a novel bone transverse carrying expander, which comprises an injection pot 1 made of silica gel, a connecting pipe 2, and an expansion bag 3, wherein one end of the connecting pipe 2 is connected with the injection pot 1, the other end is connected with the expansion bag 3, the expansion bag 3 is provided with a first expansion plate 4 and a second expansion plate 5 which are opposite to each other from top to bottom, and the first expansion plate 4 and the second expansion plate 5 are both provided with expansion metal sheets. The expansion metal sheet comprises a first metal sheet 8 and a second metal sheet 6, the first metal sheet 8 is arranged in the first expansion plate 4, the second metal sheet 6 is arranged in the second expansion plate 5, and a groove 14 and a protruding part 13 corresponding to the groove 14 are arranged on the first metal sheet 8; the expansion capsule 3 is connected in the groove 14.

Referring to fig. 3, during treatment, an arc-shaped inward longitudinal incision 11 is made on the middle lower section of a tibia 12 of a patient, so that a protrusion 13 on a first expansion plate 4 is matched with the longitudinal incision 11, the first expansion plate is fixed on the tibia 12, a second expansion plate 5 is matched with a bone piece 10, when the dilator is used, liquid is injected into an injection kettle 1, the liquid enters an expansion bag through a connecting pipe, the expansion bag is expanded, the first expansion plate and the second expansion plate achieve transverse bone transportation under the action of the expansion bag, otherwise, the expansion bag is shrunk when the liquid in the expansion bag is extracted, so that the dilator can be easily taken out, transverse bone transportation is achieved through the dilator, the operation cost is reduced, and the treatment process is simple and easy to implement. The volumes of the injected liquid in the expansion capsules are different, so that the expansion degrees of the first expansion plate and the second expansion plate are different, and the transverse movement amplitude of the bone is different.
