Abstract

The invention discloses a carbon dioxide gasbag skin expander. After a guide pin is embedded under the skin through operation, a guide tube is led outside the skin via a subcutaneous passage; after air in an expansion bag is replaced with carbon dioxide, the air expansion bag is connected to a carbon dioxide bottle via a connection pipeline and an automatic pressure regulating valve, and the automatic pressure regulating valve is set to be opened and closed at required pressure; the automatic pressure regulating valve is opened under the action of a spring when the pressure of the expansion bag decreases, and is closed under the action of an air cylinder when the pressure of the expansion bag increases; the loss of the expansion bag due to carbon dioxide dispersion is automatically compensated via the pressure regulating valve, and constant gas pressure can be kept to expand the expansion bag and further push the skin and the subcutaneous tissues outwards, so that growth and expansion of the skin and the subcutaneous tissues are facilitated.

Description

Carbon dioxide air bag skin dilator

The present invention is a kind of skin expansion medical apparatus and instruments, especially by the constant voltage dioxide capsule, implants the subcutaneous medical apparatus and instruments that carries out skin expansion.

When damaged after skin is because of wound or tumor, nevus cell nevus resection operation, contiguous normal skin is repaired damaged by expansion, can be received satisfied effect.Present known skin expansion method is by performing the operation in subcutaneous implantation silica gel expansion water pocket and injection kettle, after waiting for wound healing (approximately needing 2 time-of-weeks), by water filling, increase the volume of capsule, extruding skin is outwardly, skin surface is long-pending to be increased, and after long term (the 1-2 month), forms unnecessary skin.Shortcoming is to need after kettle by skin repeated localised puncture water filling expansion in embedding water pocket and injection, and therefore injection site may occur that infection, hematoma, the skin dilating sacculus that splits exposes complication, and patient's misery is larger.the outward expanders such as vacuum suction skin dilator are no doubt without the hands art, but can't be for axillary fossa, the depression such as webs position, also be unsuitable for local skin and organize the very tight positions such as scalp, I am in " water sac sealing carbon dioxide air bag skin dilator " (application number 200710143819.3) of declaring in 2007, proposition is expanded with dioxide capsule, and with water pocket, air bag is sealed, find that in force carbon dioxide can cause gasbag pressure to descend by the existing slow disperse of manufactured materials, although entering tissue, dioxide dispersion is conducive to tissue growth and healing, but the decline of expansion bag pressure power can make expansion lose efficacy.

The purpose of this invention is to provide a kind of skin expansion medical apparatus and instruments.By automatically remaining, implant subcutaneous dioxide capsule in constant pressure, carry out skin expansion.

the object of the present invention is achieved like this: a kind of carbon dioxide expansion capsule, by the embedding guide pin of performing the operation put subcutaneous after, by conduit outside hypodermic tunnel is drawn skin, to expand in capsule after air displacement is carbon dioxide, pass through connecting line, automatic pressure regulator connects dioxide bottle, setting the automatic Regulation valve opens and closes in required pressure, by the valve auto-compensation, expand capsule because of the carbon dioxide dissipation loss, keep constant gas pressure to make to expand the capsule expansion, and and then outwards push skin and subcutaneous tissue, the tractive that skin is continued by outwardly active force, the cell of skin and organize the irriate hypertrophy, form the unnecessary skin that surpasses the front area of expansion, be used further to repair other because of damaged wound surface of operation such as nevus cell nevuss.In addition, adopt the method to make skin to be expanded form local crowning, be convenient to adhering to of negative-pressure suction type skin dilator suction nozzle, both share and reach better expansion effect.

Owing to adopting such scheme, adopt this dilator after implantation, to start immediately expansion, without by skin repeated localised puncture water filling expansion, shorten the expansion time, use also easier.

The present invention is further described below in conjunction with drawings and Examples.
