The invention relates to the technical field of medical instruments. It is a tibial stop tunnel guide for the posterior cruciate ligament, which includes a soft leather jacket, a deformable dentate hose, an inner tube, an outer tube and a handle. The upper end of the inner tube is inserted in a deformable toothed rubber hose. The lower end of the inner tube is inserted in the handle and is fixed to the handle and the inner tube of the upper end of the handle. The outer sleeve is fixed on the outer sleeve, and a sliding device is arranged on the outer casing, and the soft leather sleeve is wrapped on the outer side of the outer tube and the deformable toothed hose. The invention has a reasonable and compact structure, and through the setting of a sliding device, a wire drawing line and a deformable toothed rubber hose, the up and down movement of the sliding device is controlled by controlling the wire drawing line to make the deformable toothed hose contract and change hook shape, so that the soft rubber tube is gradually released from the invention, and the whole process saves time, energy, efficiency, and soft skin. With soft rubber material and soft leather cover, it can prevent the soft rubber tube from damaging the popliteal artery when crossing the tibial tunnel, thus ensuring the safety of the patient.

后交叉韧带胫骨止点隧道导向器
本专利技术涉及医疗器械的
,是一种后交叉韧带胫骨止点隧道导向器。
技术介绍
膝交叉韧带为膝关节重要的稳定结构,呈铰链式连于股骨髁间窝及胫骨的髁间隆起之间,可防止胫骨沿股骨向前后移位。膝交叉韧带又可分为前后两条,前交叉韧带起自股骨外侧髁的内侧面,斜向前下方,止于胫骨髁间隆起的前部和内、外侧半月板的前角;后交叉韧带起自股骨内侧髁的外侧面,斜向后下方,止于胫骨髁间隆起的后部和外侧半月板的后角。当膝关节活动时,两条韧带各有一部分纤维处于紧张状态。人们在运动或遭受意外时,很容易发生后十字交叉韧带断裂,如果不及时治疗,就会造成膝关节不稳,严重的会影响膝关运动功能,常见的治疗手段就是重建断裂的后交叉韧带,使关节恢复应有的功能,在后交叉韧带重建手术中,需要在后交叉韧带胫骨止点上开设胫骨隧道,然后用1.0mm钢丝穿过胫骨隧道,将穿出的钢丝与事先连接在重建后交叉韧带上牵引线结扎,然后将重建的韧带从胫骨隧道内拖出,最后将韧带固定在胫骨上,进行下一步处理,由于在膝盖的后侧长有腘动脉,因此在穿钢丝的时候要十分小心,十分耗时,即便如此,也在穿钢丝的时候也会 ...
