Abstract
A kind of carbon dioxide expansion capsule, by embedding guide pin of performing the operation put subcutaneous after, conduit is drawn outside skin from hypodermic tunnel, be after carbon dioxide by air displacement in expansion capsule, pass through connecting line, automatic pressure regulator connects dioxide bottle, setting automatic Regulation valve is in required pressure opening and closing, its automatic valve is opened by spring action when expanding bag pressure power and reducing, close by cylinder action when pressure raises, by valve auto-compensation expansion capsule because of carbon dioxide dissipation loss, keep constant gas pressure that expansion capsule is expanded, and and then outwards push skin and subcutaneous tissue, make its Accretive Extensions.
Description
A kind of skin expansion medical apparatus and instruments of system of the present invention, implants the subcutaneous medical apparatus and instruments carrying out skin expansion especially by constant voltage dioxide capsule.
When after skin is because of wound or tumor, nevus cell nevus resection operation during defect, contiguous normal skin is repaired defect by expansion, satisfied effect can be received.Current 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 (about needing 2 time-of-weeks), the volume of capsule is increased by water filling, extruding skin is outwardly, skin surface is long-pending to be increased, and forms excess skin afterwards at long term (the 1-2 month).Shortcoming needs to be expanded by the water filling of skin repeated localised puncture after embedding water pocket with injection kettle, and therefore infection may appear in injection site, hematoma, skin split, and dilating sacculus exposes complication, and patient's misery is larger.The outward expanders such as vacuum suction skin dilator are no doubt without the need to hands art, but cannot axillary fossa be used for, the depressed area such as webs, also be unsuitable for local skin and organize the positions such as very tight scalp, I am in " water sac sealing carbon dioxide air bag skin dilator " (application number 200710143819.3) to declare for 2007, proposition dioxide capsule is expanded, and with water pocket, air bag is sealed, find that carbon dioxide can cause gasbag pressure to decline by the slow disperse of existing manufactured materials in force, although dioxide dispersion enters tissue be conducive to tissue growth and healing, but the decline of expansion bag pressure power then can make expansion lose efficacy.
The object of this invention is to provide a kind of skin expansion medical apparatus and instruments.Implanting subcutaneous dioxide capsule in constant pressure by automatically maintaining, carrying out skin expansion.
The object of the present invention is achieved like this: a kind of carbon dioxide expansion capsule, by embedding guide pin of performing the operation put subcutaneous after, conduit is drawn outside skin from hypodermic tunnel, be after carbon dioxide by air displacement in expansion capsule, pass through connecting line, automatic pressure regulator connects dioxide bottle, setting automatic Regulation valve is in required pressure opening and closing, by valve auto-compensation expansion capsule because of carbon dioxide dissipation loss, keep constant gas pressure that expansion capsule is expanded, and and then outwards push skin and subcutaneous tissue, the tractive that skin continues by outwardly active force, the cell of skin and organize irriate hypertrophy, formed and exceed excess skin long-pending before expansion, be used further to repair other wound surface because of surgical defect such as nevus cell nevuss.In addition, adopt the method to make skin to be expanded form local crowning, be convenient to the attachment of negative-pressure suction type skin dilator suction nozzle, both share and reach better expansion effect.
Owing to adopting such scheme, adopt this dilator to start expansion after the implantation immediately, without the need to by skin repeated localised puncture water filling expansion, shorten the expansion time, use also easier.
Below in conjunction with drawings and Examples, the present invention is further described.
