The invention discloses a simple and easy drainage device for the jaw cyst, including a drainage tube. The side of the drainage tube is symmetrically provided with two through holes, and a top column is slid in the through hole, the end of the top column is provided with a fixed plate, a connecting spring spring is connected between the two fixed plates, and the side of the inner cavity of the drainage pipe is set. The external tube is connected with a drainage inner tube, and the outer surface of the drainage inner tube is provided with an external thread. The drainage tube and the drainage inner tube are connected with the inner thread through the external thread, and the end of the drainage inner tube is provided with a circular gasket. The simple and easy drainage device for maxillofacial cyst is fixed on the principle of nut and bolt. It is fixed firmly and there is no extra additional device. The drainage mouth is concave in the bone cavity. It is not out of the mouth. The patient has a small sense of foreign body. The drainage mouth is made into a needle hole that matches the syringe. It is convenient to wash, disinfect and attract. Prevent clogging and infection.

一种简便易行颌骨囊肿引流装置
本专利技术涉及医疗器械
,具体为一种简便易行颌骨囊肿引流装置。
技术介绍
颌骨囊肿是口腔颌面外科发病率较高的颌骨良性病变。囊肿视其大小、位置及邻近的组织关系,如牙齿、上颌窦、下颌管以及骨的连续性等,可选择行剜除术、颌骨部分切除术及袋形术。当囊肿较大,波及到健康牙齿、神经束及其它重要组织结构时,现有的治疗方法,如颌骨部分切除术、剜除术,可能伤害到周围的重要组织结构,导致牙槽骨的连续性丧失,邻近牙齿的拔除及面部畸形等。而如果为了保护重要组织结构,又可能使复发几率大大升高。随着微创理念的逐步深入推广,对于大型颌骨囊肿,提倡用袋形术式的越来越多。袋形术通过小的外科手术在囊骨壁造口,使其囊腔与外界环境相通,消除囊腔内流体静压,消除骨吸收因素,从而使囊肿衬里上皮发生改变,囊壁变厚,囊腔缩小,临近骨再生。当囊肿缩小到不累及周围重要组织结构时,再行剜除术,从而大大降低了手术风险,提高了术后生活质量。经过近十几年的临床实践证明,袋形术可有效的减少传统外科手术治疗的并发症,获得良好的外形和功能恢复。但是袋形术需要获得持续的囊腔引流,临床上专利技术了 ...
