Description

经椎弓根空心椎体植骨器 Hollow pedicle bone graft device

技术领域 FIELD

该发明涉及骨科医疗器械,特别涉及一种经椎弓根空心椎体内植骨用的器械。 This invention relates to orthopedic medical device, an in particular relates to instruments pedicle hollow interbody used.

背景技术 Background technique

在脊椎外科手术中,当患者发生椎体压縮,爆裂骨折,椎体塌陷,后凸畸形,高度丢失等病症时,医生通常会对中、重度骨折患者进行椎体复位和内固定手术,爆裂骨折的椎体在后路经椎弓根器械复位固定后,椎体高度虽然得到恢复,但椎体内的骨小梁支架结构并未同时恢复,形成了椎体内的空隙,空隙内的血肿很难实现骨化,空隙使上下椎弓根钉受到强大的悬臂力作用,如不进行有效的植骨重建,则有可能在晚期发生骨折的塌陷或内固定疲劳断裂及矫正角度丢失。 In spinal surgery, when patients with vertebral compression disorders, burst fractures, vertebral collapse, kyphosis, height loss, etc., doctors usually have moderate to severe vertebral fractures were treated with reduction and internal fixation, burst Posterior vertebral fractures in post pedicle fixation device, although restored vertebral height, the trabecular stent structure within the vertebral body is not restored while forming voids within the vertebral body, hematoma voids ossification difficult to achieve, so that the vertical gap pedicle screw by a strong force of the cantilever, is not effective as bone grafting, it is possible to collapse or fatigue fracture fixation and the angle correction fracture occurred in the late loss. 这就要求椎体骨折复位后需行椎体内植骨,这对于促进骨折愈合和预防骨折椎体的塌陷起到积极作用。 This requires vertebral fractures after a reset need to line the bone graft, which play a positive role in promoting fracture healing and prevention of collapse fracture of the vertebral body. 目前常用的治疗方法是骨折复位内固定后路横突椎板植骨,而未行椎体内植骨,少数严重者可选择前路手术,前路手术植骨效果虽好,但手术时间长,损伤大,出血多,风险高,技术要求高,或者行前路后路二次联合手术。 The most commonly used treatment is transverse fracture fixation posterior lamina bone, without bone graft to the line, a few severe cases can select anterior, anterior bone graft effect is good, but a long operation time damage, bleeding, high risk, high technical requirements, secondary road posterior combined surgery before or row. 经后路非经椎弓根椎体内植骨,因椎管内神经、血管密布,植骨过程中的操作难度很大,易损伤神经、血管,出血多, 一旦损伤神经或血管,则会给患者造成严重的后果。 By posterior pedicle bone graft non, because of spinal nerves, blood vessels clouds, great difficulty of the operation grafting process, easy to damage nerves, blood vessels, bleeding, damage to nerves or blood vessels once, it will serious consequences for the patient. 有一种新的植骨方法是经后路经椎弓根椎体内植骨,该手术可与复位内固定手术一起完成,避免二次手术,减少病人痛苦。 There is a new bone is pedicle screw after the bone graft, the procedure can be completed with internal fixation, to avoid the second operation, reduce patient suffering. 目前手术是用经椎弓根锥子钻孔后,插入特殊漏斗进行植骨,操作过程中易变位,极易穿破骨皮质,加上椎体骨折复位后存在缺隙,则极易因器械插入过深而损伤前方大血管,危及生命,其操作的技术要求很高,因没有相应的专门器械进行准确操作,主要依靠医生凭经验操作,但因风险太大,许多患者和医生不得不放弃,尚未推广应用。 After the drilling operation is currently pedicle awl, bone insert special funnel, variable bit during operation, easy to puncture the cortical bone, with the presence of the missing gap vertebral fractures, the device vulnerable to inserted too deep in front of the great vessels injury, life-threatening, high technical requirements of its operations, because there is no corresponding specialized instruments for accurate operation, doctors rely mainly on their experience operating, but the risk is too high, many patients and doctors had to give up It has not been widely applied. 发明内容 SUMMARY
