Abstract

The invention relates to a syndactylia skin expander. The syndactylia skin expander comprises an expander main body, a metal core guide pin and a water injecting vale, wherein the expander main body sleeves the upper part of the metal core guide pin, the water injecting vale communicates with the expander main body through a capillary channel, the water injecting valve injects normal saline into the expander main body, the upper part of the expander main body is expanded to form the columnar shape, and the lower part of the expander main body is expanded to form the ball shape. Compared with the prior art, the syndactylia skin expander has the advantages that syndactylia separation can be completed at once, skin grafting is not needed, the operation is safe and reliable, and the surgery is simplified.

Description

technical field

[0001] The invention relates to a skin dilator. Background technique

[0002] At present, the following treatment measures are mainly taken for the separation of syndactyly: direct separation of syndactyly, taking skin and grafting, this method needs to take skin from other parts, causing damage to other parts, and there is a risk of skin grafting and necrosis at the same time, which will occur after skin necrosis Scar contractures lead to deformities; the design of webbed skin usually uses star-shaped flaps, rectangular flaps, triangular flaps, etc., and the design is relatively difficult.

[0003] In recent years, some people use an external fixator to fix the adjacent finger bones, and then gradually increase the force, so that the fingers are separated and the skin between the fingers is extended. However, this method prolongs the skin between the fingers, but the skin between the webs does not The skin was still tense after the finger webs were separate...
