The utility model discloses a skin tractor at the extremity end, which comprises a pull rod, a pull adjustment nut and a pull hook. The outer surface of the pull rod is provided with external threads and scale threads for displaying the pull length. One end of the pull rod is provided with conical spikes. The internal threads of the pull adjustment nut are matched with the external threads. The pull adjustment nut is sleeved on the pull rod and the external threads are arranged on the pull rod. The threads mesh with the internal threads. The tension adjusting nut can move back and forth along the axial direction of the pull rod by turning along its circumference. The pull hook includes several pull hooks for pulling soft tissues such as skin. The pull hook is connected with the tension adjusting nut through the connecting component. The utility model has a pull adjusting nut and a pull rod thread matching, and the thread matching can self-lock. The pull hook can pull the skin by connecting components. The scale thread arranged on the pull rod can enable the surgeon to quantify the length of the skin pull, which is efficient and convenient.

一种肢端皮肤牵拉器
本技术涉及医疗器械,具体涉及一种肢端皮肤牵拉器。
技术介绍
目前,皮肤组织修复和器官再造时通常采用传统的皮肤软组织扩张器埋植术,这种方法是将扩张器置入正常皮肤下方,通过注射壶向扩张囊内注射液体增加扩张器容量,对表面皮肤产生压力,通过生长和弹性扩张增加额外皮肤的面积,但它存在以下缺点:(一)手术需分次进行,治疗时间长,一般需2~3个月;(二)注射生理盐水时,患者感到疼痛、坠胀,尤其到注射后期,扩张部位隆起后有碍美观并影响日常生活;(三)术后并发症发生率较高,临床上也有的使用皮肤伸展器对皮肤进行拉紧扩张,但目前使用的皮肤伸展器,结构复杂,皮肤拉紧扩张时间长,且不能直接覆盖创面,病人痛苦大。为此,中国技术专利CN203059796U公开了一种双向皮肤牵拉器,其结构包括:拉杆、两个对合针槽、两个套杆、两套对合针和两个固定夹,其中,拉杆上表面设置有锯齿状突起,套杆的两端具有端部突起,固定夹的两端具有内外两对与所述的端部突起配套的卡槽;两套对合针分别通过配套的卡扣安装在两个套杆上,两个套杆分别通过可拆卸的嵌入式结构安装在两个对合针槽上,两个对合针槽分别套在 ...
