负压封闭引流装置与骨科穿针密封连接的密封胶圈及引流 Vacuum sealing means sealing gasket drainage and drainage orthopedic needle sealing connection

系统 system

技术领域 FIELD

[0001] 本实用新型涉及医疗机械领域,具体地说是一种负压封闭引流装置与骨科穿针密封连接的密封胶圈及引流系统。 [0001] The present invention relates to the field of medical equipment, in particular an orthopedic device VSD needle sealing gasket and connected to the drainage system.

背景技术 Background technique

[0002] 负压封闭引流技术(vacuum sealing drainage,简称VSD)是德国ULM大学Wim Fleischman博士于1992年首创,并形成理论雏形,用于四肢创面的引流;1994年中国裘华德教授首次将负压封闭引流技术应用于普外科,开创了负压封闭引流技术在普外科应用的先河。 [0002] VSD technology (vacuum sealing drainage, referred to VSD) is Dr. Wim Fleischman ULM, Germany's first university in 1992, and formed the theoretical prototype for wound drainage limbs; in 1994, the first Chinese professor Qiu Huade vacuum sealing drainage technology in general surgery, creating a vacuum sealing drainage precedent in general surgery applications. 王彦峰、裘华德教授在中国于1998年3月18日得到授权的专利CN 2276350,为负压封闭引流技术的第一个专利。 Professor Wang Yanfeng, Qiu Huade on March 18, 1998 authorized the Chinese patent CN 2276350, for the VSD technology first patent. 从此,负压封闭引流技术在我国得到了较大的发展。 Since then, the VSD technology in China has been great development.

[0003] 负压封闭引流技术是通过负压封闭引流系统来实现的,它包括多孔泡沫软垫、一端设置在多孔泡沫软垫内的引流管、用于密封多孔泡沫软垫的密封薄膜。 [0003] VSD technique is accomplished by vacuum sealing drainage system, which comprises a porous foam cushion, one end of the drainage tube is disposed within the porous foam cushion, a sealing film for sealing the porous foam pad. 将装配引流管的多孔泡沫软垫铺设在创面上,用密封薄膜密封,并将引流管接通负压,从而在创面处建立了一个封闭的引流区,进行持续地负压封闭引流。 The porous foam cushion assembly drainage tube laid on the wound sealed with a sealing film, and vacuum drainage tube is turned on, thus establishing a closed drainage area at the wound, a continuous vacuum sealing drainage. 与现有的普通换药相比,负压封闭引流技术能将被引流区内的渗出物和坏死组织通过多孔泡沫软垫及引流管非常及时地清除,从而使被引流区可达到“零积聚”状态,创面能够处于持续的清洁环境下,大大降低了机体对毒素的重吸收;即使有较大的腔隙存在,腔隙也因负压的存在而加速缩小。 Compared with the conventional ordinary dressing, VSD technology can be draining exudate and necrotic tissue area very promptly cleared by the drainage tube and the porous foamed cushion, so that is can achieve "zero drainage area accumulation "state, can be wound in a clean environment under constant, significantly reduced the body weight of the absorbent toxin; even when large cavities exist, but also by the presence of negative pressure cavities is accelerated reduction. 对浅表创面而言,密封薄膜和多孔泡沫软垫也使局部环境更接近生理性的湿润状态;同时,作用于创面软组织上的负压刺激,有利于局部微环境的改善和组织水肿的消退,加速了创面中肉芽组织的新生,缩短创面愈合时间。 Superficial wounds, the sealing film and the porous foamed cushion makes the local environment closer to physiological wet state; the same time, the negative pressure applied to the wound on the soft tissue irritation, improve and facilitate tissue edema subsided microenvironment accelerate the nascent granulation tissue in the wound and shorten healing time. 在负压封闭引流技术治疗下,创面3-7天内无需换药,降低了医务人员的工作量,减少了患者痛苦,降低了综合医疗费用。 In the vacuum sealing drainage treatment, the wound dressing 3-7 days without the need to reduce the workload of medical staff, to reduce the suffering of patients and reduce overall health care costs.

[0004] 在我国负压封闭引流技术已广泛适用于:创伤科、骨科、普外科、烧伤科等领域。 [0004] In our country VSD technology has been widely applied to: the field of traumatology, orthopedics, general surgery, burn and so on.

[0005] 然而,受限于现有骨科外固定技术操作的规范流程和治疗原则,现有的负压封闭引流技术在骨科外固定技术下创面的操作仍存在密封极其不便,及密封不严密导致负压封闭引流技术失效的问题。 [0005] However, the process is limited to a fixed technical specifications to existing operations and orthopedic treatment principles, conventional vacuum sealing drainage operation wounds remain fixed on the outer orthopedic sealing techniques is extremely inconvenient, and cause dense Mifengbuyan vacuum sealing drainage problems of technical failure. 而良好的密封是保证引流效果的关键,也是整个负压封闭引流操作中最困难之处。 And sealing is the key to good drainage effect, but also the entire operation of the VSD most difficult place. 往往肢体有创面时大都伴随有骨折,而开放性骨折的治疗原则是必须采用外固定。 Most often accompanied by limb fractures when there are wounds, open fractures and principles of treatment are necessary with external fixation. 现有骨科外固定技术的操作的规范流程是:首先对骨折断端部位近端和远端进行复位,使用穿针经皮对骨折断端进行半穿刺或全穿刺;穿刺完成后将固定连接件装设在穿针上,然后将连杆装设在固定连接件上调整角度固定,装配成为一个完整的骨科外固定装置将骨折处固定牢固;最后使用裁剪后的泡沫软垫覆盖有穿针穿出处的皮肤及软组织缺损部位,并用裁剪后的密封薄膜密封。 Existing orthopedic external fixation standard process operations is: first portions of the proximal and distal fracture fragments is reset, percutaneous needle used to puncture the fracture fragments or full half-puncturing; after completion of the piercing member fixedly connected mounted on the needle, and then adjust the angle of the link is mounted on the fixing member is fixedly connected, assembled into a complete fixation orthopedic external fracture fixation device; and finally cut the foam cushion covered with the used needle through provenance skin and soft tissue defect site, and sealed with a sealing film after cutting. 治疗原则是先用骨科外固定装置固定好骨折患处,然后进行创面处理和密封操作;在骨折患处未固定完好前不允许进行任何针对患处的其它操作,以免复位的骨头再次被断开。 Principle of treatment is to use external orthopedic fracture fixation means fixed lesion, wound treatment and then subjected to a sealing operation; any other operation on the affected area of ​​the affected area is not allowed in fracture fixation before intact, so as to be opened again reset bones. 这种操作流程和治疗原则下,对带有骨科外固定装置下的创面密封需要极其细心和繁琐的操作,多孔泡沫软垫与穿针的连接处极易密封不严密,是极其容易漏气的地方。 This operation flow treatment and principles, with the sealing wounds in orthopedic external fixation apparatus requires very careful and complex operation, and piercing the porous foam cushion Mifengbuyan highly dense connection, is extremely easy to leak local. 常用的密封方法包括:戳孔法、“系膜”法、缝合法及“包饺子”法等(《负压封闭引流技术》第2版P20-P24,裘华德宋九宏主编,人民卫生出版社出版),对于骨科外固定装置的密封通常使用密封薄膜对贴法,即使用两片密封薄膜对贴来密封穿针。 Commonly used sealing method comprising: puncture method "membrane-based" method, and the suture "dumplings" method ( "VSD Technology" 2nd Edition P20-P24, Qiu Huade Songjiu Hong editor, People's Health Publishing House) for external orthopedic fixation devices typically use a sealing film to seal paste method, i.e., using two of the sealing film to seal the needle attached. 有时甚至为达到密封的效果,不惜耗费大量时间和精力,将整个骨科外固定装置用密封薄膜包裹起来。 Sometimes even to achieve the effect of sealing, willing to spend a lot of time and effort, the entire outer wrap orthopedic fixation device with a sealing film. 上述的密封方法在实际的操作中均非常繁琐,手术医生均需要进行反复的操作和练习才能掌握,且操作时间长,病人极为痛苦。 Above sealing methods are cumbersome in actual operation, surgeons require repeated operations and practice to master, and the operation for a long time, the patient is extremely painful. 同时,由于需长时间操作,病人会大量吸入麻醉药,给病人带来极为严重的副作用,甚至会因为麻醉药吸入过多造成病人脑死亡。 At the same time, due to the need for a long time operation, the patient will be a lot of inhaled anesthetics to patients bring very serious side effects and even cause the patient brain dead because excessive inhalation anesthetic. 而且上述方法密封仍不牢固,仅靠贴膜极难完成密封,漏气率达90%以上,极易造成因漏气而导致负压封闭引流系统的治疗效果削弱甚至失败。 And the above-described method of sealing is still strong, extremely difficult to complete the seal film alone, leakage rate of 90%, can easily result in leakage caused by treatment VSD system weaken or even fail. 即使密封完整,穿针对贴处仍然会因不断渗出的组织液的积累,使得对贴膜粘性消失而导致密封失效。 Even if the seal intact, still wearing for a posted at the leakage due to the continuous accumulation of tissue fluid, so that the viscosity of the film disappear and lead to seal failure. 而负压封闭引流系统的治疗效果削弱甚至失败后,穿针处极易出现感染,而且会顺着穿针一直延伸至骨腔内;骨腔内感染化脓后,由于血供不足、且位于骨头内,脓液极难排出,引发创伤性骨髓炎,病人往往会疼痛难忍,十分痛苦。 Treating effect VSD system compromised even after the failure of the needle prone to infection, and will extend along the needle to the bone cavity; purulent infection after bone cavity, due to lack of blood supply, and is located in the bone inside, extremely difficult to discharge pus, causing traumatic osteomyelitis, patients often painful, very painful. 而创伤性骨髓炎治疗代价极为高昂,治疗也极为困难,甚至经久迁延不愈,而在治疗过程中反复刺激创面还可能引发鳞状上皮细胞癌的产生。 Traumatic and extremely costly treatment of osteomyelitis, treatment extremely difficult, even prolonged delayed healing, and in the course of treatment may also lead to repeated stimulation of wound produced squamous cell carcinoma.

[0006] 因此,对现有的在加装骨科外固定装置后的负压封闭引流技术密封进行改进,提高密封的严密性对整个负压封闭引流技术的发展有着重要意义。 [0006] Thus, the existing fixing means after the negative pressure on the outer seal sealing drainage installation orthopedic improve, enhance tight sealing of the entire vacuum sealing drainage development is of great significance.
