Title
(EN) Device and method for distraction of the spinal disc space
(ZH) 脊椎盘腔牵引用的设备和方法
Abstract
(EN)
An extractable device is used to insert a medicinal filling into a spinal disc. The device comprises a filling member and a flowable medicine. The filling member is made of a flexible and permeable wall and is provided with a holding portion and an injection port via which the flowable medicine is injected into the holding portion after the filling member is inserted into the spinal disc. The holding portion is provided with an opening which is releasably lashed by one end of one or more threads so as to make the opening leakproof. Upon completion of solidification of the flowable medicine in the holding portion of the filling member, other end of the thread is pulled to unlash the opening of the holding portion, thereby enabling the filling member to be extracted from the spinal disc so as to leave only the medicine in the spinal disc.

一个用来将药用填充物插入脊椎盘内的可抽出的设备。该设备包括一个填充件和一个流质药。填充件用挠性可渗透壁制成,上有一个存药区和一个喷射口,在填充件插入到脊椎盘内后,流质药就是通过该喷射口喷射到存药区内。存药区有一个开口,该开口可以用一根或多根细线的一端扎紧,但也可以松开,从而形成该开口防漏。流质药在填充件的存药区内凝固后,细线的另一端可以抽出,使存药区的开口松开,从而,可以将填充件从脊椎盘中抽出,只将药留存在脊椎盘中。
