Abstract
The utility model relates to a medical apparatus for skin expansion, which is composed of a detecting needle, a guide needle, an expansion bag, a transfusion apparatus with two chambers, a disposable sterile sleeve article, a pressurizing box, a device for reducing, increasing and detecting pressure, and a back bag. After the detecting needle punctures skin, the guide needle is used for placing the expansion bag below skin, then the guide needle can be drawn out, and the expansion bag is connected with a liquid storing bag coated by an air bag via an infusion pipe. A bag with two chambers is arranged in the pressurizing box for conducting air exhaust, air injection and pressure measurement to the inside of the air bag via a valve port. The constant and lasting pressure of the air bag is used for pushing sterile brine in an infusion bag, and the sterile brine flows into the expansion bag below the skin for expanding the expansion bag via the infusion pipe. Constant pressure is used for pushing the skin outwards, and the purpose of skin expansion can be achieved. During the process of continuous expansion, the back bag is used for keeping the apparatus portable.
Description
This utility model is a kind of skin expansion apparatus, especially implants the subcutaneous medical apparatus and instruments that carries out skin expansion by simple puncture.Its design is based on " piercer implanting type skin dilator " invention and done partly change.
When damaged, it is damaged to repair that contiguous normal skin is increased area by expansion, can receive satisfied effect after skin is because of wound or tumor, nevus cell nevus resection operation.Present known skin expansion method is by performing the operation in subcutaneous implantation silica gel expansion capsule and injection kettle, after waiting for wound healing (needing 2 time-of-weeks approximately), carry out the volume of skin penetrating water filling in injection kettle increase capsule repeatedly, extruding skin outwards protrudes, skin surface is long-pending to be increased, and forms unnecessary skin in long term (about January) back.Utilize this part unnecessary normal skin, cover the skin injury after cicatrix, tumor and nevus cell nevus excise.Shortcoming is to need operation when embedding expansion capsule and injection kettle, treat to begin the water filling expansion after the otch healing (needing 2 time-of-weeks approximately), and infection, hematoma, the skin expansion capsule that splits may occur and expose complication, need once operation when excising nevus cell nevus and utilizing the skin expansion flap coverage again, add skin penetrating water filling repeatedly, patient's misery is bigger.Outward expanders such as vacuum suction skin dilator no doubt need not operation, but can't be used for depression positions such as axillary fossa, webs, also are unsuitable for local skin and organize very tight positions such as scalp.
The purpose of this utility model provides a kind of skin expansion medical apparatus and instruments.By simple puncture special disposable expansion capsule is implanted subcutaneously, and begun constant voltage water filling expansion immediately, be used in combination separately or with the negative pressure attraction type skin dilator and reach the purpose of skin expansion.
The purpose of this utility model is achieved in that a kind of special expansion capsule, by guide pin place subcutaneous after, be connected with transfusion device and constant voltage generating means again.
During use, make a miniature incision in skin, use medical metal or rigid plastics probe in subcutaneous formation tunnel, rigid plastics or metallic pin are inserted the expansion capsule, to expand capsule again imports in the hypodermic tunnel, extract guide pin and will expand capsule and keep somewhere, be connected by the liquid storage cylinder of tube for transfusion with the two-chamber bag in subcutaneous.This bag is placed in the constant voltage pressue device for the double cavity structure of air bag parcel liquid storing bag.Closed back utilizes inflates ball by valve injecting compressed air in air bag, and detects intracapsular pressure by air gauge, when reach certain pressure and stable after valve-off.Utilize the compressibility of gas to keep the constant of air bag internal gas pressure, then liquid enters the expansion capsule with constant compression force by tube for transfusion and makes its expansion in the squeeze bag, and and then outwards push skin and subcutaneous tissue, skin is subjected to the outwards lasting tractive of active force of protrusion, the cell of skin and organize the irriate hypertrophy, form the unnecessary skin that surpasses the preceding area of expansion, be used further to repair other because of damaged wound surface of operation such as nevus cell nevuss.In addition, adopt this method to make skin to be expanded form local crowning, be convenient to adhering to of negative pressure attraction type skin dilator suction nozzle, both share and reach better expansion effect.Wherein probe, expansion capsule, guide pin, tube for transfusion and two-chamber transfusion device are the aseptic disposable product, and the constant voltage generating means is that haversack is portable, and is easy to use, and helps preventing cross infection.
Owing to adopt such scheme, adopt this dilator when skin expansion, to need not operation, after implanting, puncture begins expansion immediately, shorten the expansion time, use also easier.
Below in conjunction with drawings and Examples this utility model is further specified.
