Abstract
The utility model relates to a medical apparatus, which can cause normal skin to be dilated for repairing the defect of the skin, and is characterized in that the utility model is composed of a specially made suction nozzle, a suction tube and a negative-pressure suction device. The specially made suction nozzle with a flat cavity (with larger internal surface area and volume proportion) is connected with the negative-pressure suction device through a hard air guiding tube. When is used, the utility model contacts with skin at the region to be dilated, and after the negative-pressure suction device is started, the skin and a small amount of soft tissue under the suction nozzle project towards the inner of a suction nozzle cavity caused by pressure difference, and the skin is dragged, expanded and dilated along an inner wall of the suction nozzle, so as to achieve the purpose of dilating the skin for repairing the defect of skin caused by traumas and operations.
Description
This utility model is a kind of skin expansion apparatus, especially can be at the external medical apparatus and instruments that makes skin obtain expanding with non-operative treatment.
After skin is because of wound or tumor, nevus cell nevus resection operation when damaged, contiguous normal skin is repaired damaged by expansion, can receive satisfied effect.Present known skin expansion method is by performing the operation in subcutaneous implantation silica gel dilating sacculus, treat the otch healing after, increase the volume of capsule by water filling, extruding skin outwards protrudes, skin surface is long-pending to be increased, and forms unnecessary skin in long term (the 1-2 month) back.Utilize this part unnecessary normal skin, cover the skin injury after nevus cell nevus excises.Shortcoming is to need operation when embedding sacculus, and infection, hematoma, the skin dilating sacculus that splits may occur and expose complication, excision nevus cell nevus and need once operation again when utilizing the skin expansion flap coverage, and patient's misery is bigger.
The purpose of this utility model provides a kind of skin expansion medical apparatus and instruments.It expands outwardly skin to reach the purpose of skin expansion by vacuum suction.
The purpose of this utility model is achieved in that a kind of special band flat chamber suction nozzle, and by suction nozzle top valve, joint is connected with vacuum extractor with suction catheter, Pressure gauge.
During use, suction nozzle mouth and the contact skin for the treatment of extended region, after starting vacuum extractor, skin under the suction nozzle and a small amount of soft tissue are projecting inward to suction nozzle because of pressure differential, skin prolongs the suction nozzle inwall and is pulled the stretching, extension expansion, after reaching certain negative pressure (40-50 millimetres of mercury), close the valve at suction nozzle top, under suction nozzle intracavity negative pressure continuous action, skin is subjected to the tractive that continues to the active force of suction nozzle intracavity, and the cell of skin and organize the irriate hypertrophy is behind long term (1-2 month), 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.Because flat suction nozzle inner volume is little, when skin stretches expansion, the subcutaneous tissue that unlikely generation is too much.
Owing to adopt such scheme, adopt this dilator when skin expansion, to need not operation, use also easier.
Below in conjunction with accompanying drawing this utility model is further specified.
