Beschreibung  übersetzt aus folgender Sprache: Chinesisch

二氧化碳气囊皮肤扩张器 Carbon dioxide balloon dilator skin

[0001] 本发明系一种皮肤扩张医疗器械,尤其是通过恒压二氧化碳气囊植入皮下进行皮肤扩张的医疗器械。 [0001] The present invention is a skin expansion of medical equipment, especially the skin subcutaneously implanted medical device through constant expansion of carbon dioxide airbags.

[0002] 当皮肤因外伤或肿瘤、色素痣切除手术后缺损时,将邻近的正常皮肤通过扩张修补缺损,会收到满意的效果。 [0002] When the skin due to trauma or tumor, when nevi defect after resection, the adjacent normal skin repair defects through the expansion, will receive satisfactory results. 目前公知的皮肤扩张方法通过手术于皮下埋置硅胶扩张水囊与注射壶,等待切口愈合(约需2周时间)后,通过注水增大囊的体积,挤压皮肤向外凸出,皮肤表面积增加,在长期作用(1-2月)后形成多余皮肤。 Currently known method of tissue expansion surgery in subcutaneous buried by silica expansion bladders and injection port, waiting for wound healing (about two weeks time), by increasing the volume of the water bag, outwardly projecting squeeze the skin, the skin surface area increase in the long-term role in the formation of excess skin (January-February) after. 缺点是在埋置水囊与注射壶后需要通过皮肤反复穿刺注水扩张,注射部位因此可能出现出现感染、血肿、皮肤裂开扩张球囊外露并发症,病人痛苦较大。 The disadvantage is that, after the injection pot buried bladders repeated puncture injection through the skin dilate, which may occur at the injection site infection, hematoma, dilatation balloon exposed skin breakdown complications, patient suffering greatly. 负压吸引皮肤扩张器等外扩张器固然无需手术,但无法用于腋窝、指缝等凹陷部位,也不适于局部皮肤组织很紧的头皮等部位,本人在2007年申报的《水囊密封二氧化碳气囊皮肤扩张器》(申请号200710143819.3)中,提出用二氧化碳气囊进行扩张,并以水囊对气囊进行密封,在实施中发现二氧化碳会通过现有制造材料缓慢弥散而导致气囊压力下降,尽管二氧化碳弥散入组织有利于组织生长与愈合,但扩张囊压力的下降则会使扩张失效。 Suction substandard skin dilator dilator of course without surgery, but can not be used armpits, fingers and other parts of the recess, is not suitable for local dermal tissue of the scalp and other parts very tight, "he declared bladders seal carbon dioxide in 2007 balloon dilator skin "in the (Application No. 200710143819.3), made balloon dilatation performed using carbon dioxide, and water bladders to seal the balloon, found in the implementation of the carbon dioxide will slowly diffuse through existing manufacturing materials caused by balloon pressure drop, although carbon dioxide dispersion the organization is conducive to tissue growth and healing, but expanding balloon pressure drop will make the expansion of the failure.

[0003] 本发明的目的是提供一种皮肤扩张医疗器械。 [0003] The object of the present invention is to provide a skin expansion medical devices. 通过自动维持植入皮下的二氧化碳气囊于恒定压力,进行皮肤扩张。 By automatically maintaining the balloon implanted under the skin of carbon dioxide at a constant pressure, a skin expansion.

[0004] 本发明的目的是这样实现的:一种二氧化碳气体扩张囊,通过手术埋置导针置皮下后,将导管自皮下隧道引出皮外,将扩张囊内空气置换为二氧化碳气体后,通过连接管路、自动调压阀接二氧化碳气瓶,设定自动调压阀门于所需压力开闭,通过阀门自动补偿扩张囊因二氧化碳气体弥散损失,保持恒定气体压力使扩张囊扩张,并进而向外推挤皮肤及皮下组织,皮肤受向外凸出的作用力持续的牵拉,皮肤的细胞及组织受刺激增生,形成超过扩张前面积的多余皮肤,再用于修复其他因色素痣等手术缺损的创面。 [0004] The object of the present invention is implemented as follows: one carbon dioxide gas expander, after surgically embedded guide pin set subcutaneous catheter subcutaneous tunnel leads from the outer skin, the expansion of the air sac after replacing the carbon dioxide gas, through connecting pipe, automatic regulator then carbon dioxide cylinders, set the automatic pressure regulating valve opening and closing the door to the desired pressure, due to carbon dioxide gas balloon dilatation compensation diffusion losses through the valve automatically maintain a constant gas pressure dilatation balloon dilation, and thus to Skin and subcutaneous tissue outside push, skin that outwardly projecting continued pulling force, the skin cells and tissues by stimulating proliferation, the formation of the excess over the expansion of the front area of the skin, then used to repair other factors, such as surgery nevi defect wound. 此外,采用该方法使待扩张的皮肤形成局部凸起,便于负压吸引式皮肤扩张器吸头的附着,两者合用达到更好的扩张效果。 In addition, using this method allows the skin to be expanded to form a local projection, easy to suction-type skin dilator tip is attached, the two combined to achieve better expansion effect.

[0005] 由于采用上述方案,采用该扩张器在植入后立即开始扩张,无需通过皮肤反复穿刺注水扩张,缩短扩张时间,使用也比较简便。 [0005] As a result of the above programs, the use of the stent after implantation immediately began to expand without having to repeatedly puncture injection through the skin dilate, shorten the expansion time, use is also relatively simple.
