Problems solved by technology

[0003] In the process of ELF EARS-SET elf ear reconstruction, a skin expander is needed to obtain normal skin and soft tissue for tissue repair and reconstruction, while the existing skin expander needs to be injected regularly during the use process. Syringes are often used, and since the syringes need to be manually powered for injection during operation, the injection speed is inconvenient for centralized control when used by different personnel. Excessive speed may cause discomfort to the patient. cause necrosis of the dilated part

Abstract

The invention provides a skin dilator applied to elf ear reconstruction, and the skin expander comprises a dilation bag which is implanted into the skin at the position where elf ear is planted and is used for dilating the skin; a catheter which is used for conveying filling liquid into the expansion bag to enable the expansion bag to expand; and an injection mechanism which comprises a storage pipeline, an adjusting unit and a driving unit, wherein the driving unit is connected with the adjusting unit, and the driving unit provides slow and constant-speed power for the adjusting unit. The invention has the beneficial effects that the driving unit arranged on the injection mechanism can drive the buffer mechanism to slowly move at a constant speed, manual pushing for injection is not needed during injection, the injection speed can be unified during operation by different workers, pain of a patient caused by the too high injection speed can be effectively prevented, and pains caused by too fast tension of the expansion bag can be prevented.

Description

technical field [0001] The present invention relates to the technical field of human face-lifting equipment, in particular to a skin expander applied to elf ear reconstruction and a method for using the skin expander applied to elf ear reconstruction. Background technique [0002] The skin expander is an advanced treatment method unique to plastic surgery. Its principle is to implant the skin soft tissue expander under the normal skin soft tissue near the lesion, and increase the capacity of the expander by intermittently injecting liquid into the expansion sac, so that it can affect the surface skin soft tissue. Pressure is generated, and the division and proliferation of tissue and epidermal cells and the expansion of cell gaps are caused by the expansion mechanism on the local area, thereby increasing the skin area. After removing the expansion sac, the newly increased skin soft tissue can be used for tissue repair and organ reconstruction. The clinically used dilator is ...
