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

二氧化碳气囊皮肤扩张器 CO balloon skin expander

[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 expandable medical device, in particular a skin expandable medical device implanted subcutaneously constant voltage CO balloon.

[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 resection when the defect nevi, normal skin adjacent to 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 skin expansion surgically embedded in silica gel expansion bladders and the subcutaneous injection port, waiting for wound healing (about 2 weeks) after injection by increasing the volume of the bladder, skin pressed outwardly projecting, surface area of ​​skin increase the formation of excess skin (January-February) after the long-term effects. 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 and need to repeatedly puncture injection through the skin dilate, and therefore may occur at the injection site infection, hematoma, skin breakdown dilatation balloon exposed complications, patients greater pain. 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 skin expander substandard dilator of course without surgery, but can not be used armpits, fingers and other parts of the depression, not suitable for topical skin tight scalp and other parts, declared in 2007 "seal bladders carbon dioxide balloon skin expander "(application No. 200710143819.3), it is proposed for balloon dilatation with carbon dioxide, and water bag to seal the balloon, carbon dioxide will be found in the embodiment manufactured by a conventional slow diffusion material resulting balloon pressure drop, although carbon dioxide dispersion the organization is conducive to tissue growth and healing, but the expansion will decrease bladder pressure of the expansion fails.

[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 expandable medical device. 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。 At constant pressure, by automatically maintaining a skin expansion subcutaneously implanted carbon dioxide airbag.

[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: A carbon dioxide gas expansion balloon, the guide pin embedded surgically placed subcutaneously, subcutaneous tunnel leads from the catheter outer sheath, the expansion of the air sac is replaced with carbon dioxide gas, by connecting line, automatic pressure regulating valve then carbon dioxide gas cylinder, is automatically set to the desired pressure regulating valve opening and closing doors, the compensation due to the carbon dioxide gas expandable balloon diffusion losses through the valve automatically maintain a constant gas pressure expansion balloon dilation, and thus the pushing the outer skin and subcutaneous tissue, skin outwardly projecting force by pulling continuous, tissue cells and the proliferation of skin irritation, is formed over the front area of ​​the excess skin expansion, then other factors for the repair operation and the like nevi defect wounds. 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。 Furthermore, the method makes use of the skin to be expanded to form a local protrusion, facilitates suction-type skin dilator tip is attached, the expansion of the two combined to achieve better results.

[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] Since the above-described embodiment, the use of the expanded stent after implantation starts immediately, without the need for repeated puncture skin injection expansion, the expansion time is shortened, but also relatively simple to use.
