The double-deck saddle-shaped lateral distraction pad is used to maintain the patient's lateral position during endoscopic spine surgery (foramen endoscopy). The appearance is saddle-shaped, and the interior is divided into two layers, with an independent inflatable tube of the air bag. When the upper air bag is inflated, the opening cushion is saddle-shaped. When the lower air bag is inflated, the height of the opening cushion can be increased by 10 cm. When the patient is in lateral position, the waist of the patient is placed in the depression in the middle of the saddle-shaped support pad. The front uplift is supported in the abdomen, and the rear uplift is supported in the back and waist, forming a front-back obstruction. This saddle-shaped pad can raise the lumbar spine from bottom to top to cause lumbar lateral bending. It can lower the edge of pelvic iliac crest, open one side of the intervertebral disc and increase the height of one side of the intervertebral foramen. At the same time, the saddle-shaped design can prevent the body from swaying back and forth, and facilitate the fine operation of the foramen mirror operation. The double-deck inflatable design is easy to adjust the height of the support pad according to the need of operation, and avoid serious discomfort caused by prolonged over-stretching of the waist and the lumbar spine in the state of lateral bending.
【技术实现步骤摘要】
一款双层设计的马鞍形腰椎侧方撑开垫
本技术属于医疗器械领域,具体涉及一种用于脊柱内镜(椎间孔镜)手术中稳定病人身体位置、方便脊柱内镜(椎间孔镜)手术操作的专用撑开垫。
技术介绍
大部分脊柱内镜(椎间孔镜)手术采用侧卧位,即病人侧卧在手术台上,病变侧在上、健侧在下。手术操作分为两部分:①向病变的椎间盘和椎间孔部位置入工作套筒、椎间孔镜;②椎间孔镜下进行神经减压。实施第一步操作时需要在手术床上放置一个腰部垫,支撑在健侧的腰部,将腰椎向上顶起,造成轻度的脊柱侧弯,增加病变侧椎间孔和椎间盘间隙的高度。同时可以下移髂嵴,方便将工作通道通过椎间孔准确置入到病变的椎间盘部位。在完成第一部分的工作通道置入操作后,就不再需要将腰椎顶在这个不舒服的侧弯状态了,这时通常的做法是让手术台下的助手用力抽出这个软垫。但是,由于病人整个身体压在软垫上,抽出软垫非常困难,而且容易失控而污染无菌的手术区域。另外,普通软垫仅仅能够起到顶起腰椎的作用,没法控制身体向前倾或向后倒,术中每次透视都需要调整病人的体位。因此,需要有一款能够将病人控制在标准的侧卧位,同时在完成脊柱内镜(椎间孔镜)手术第一部分置管操作后,又可以降低软垫高度,让病人在一个较为舒适的位置完成后续操作的专用腰部侧方撑开垫。
技术实现思路
这款双层设计的马鞍形腰部侧方撑开垫,外观呈马鞍形,即前方和后方隆起、中间凹陷(图1)。撑开垫横放在手术台上,病人侧卧位躺在撑开垫上,马鞍形撑开垫前方的隆起支撑在腹部,防止身体前倾,后方隆起支撑在腰部,防止身体后仰,中间凹陷处支撑在下方一侧的腰部,能够将腰椎向上方顶起。撑开垫由外套、内部的气囊和充气管组 ...
