Description

说 明 书 一种用于脊柱后路微创置钉小切口的撑开维持装置 技术领域  Description: A distraction maintenance device for minimally invasive small incision in the posterior spinal column
本发明涉及一种用于脊柱后路微创置钉小切口的撑开维持装置， 属于医疗器械领域。  The invention relates to a distraction maintenance device for a minimally invasive small incision in the posterior spinal column, belonging to the field of medical instruments.
背景技术 Background technique
椎弓根螺钉技术自上世纪 80 年代问世以来发展迅速， 已经广泛应用于脊柱退行性变、 椎 体滑脱、 椎管狭窄、 椎体骨折、 畸形、 骨转移瘤、 脊柱失稳等疾患的手术治疗。 近年来小切 口或者经皮微创置钉已经逐步开展并为临床医师广泛接受， 但在小切口情况下置钉后仍需要 多次暴露小切口进行安棒及撑开， 需要反复多次暴露， 暴露的过程不光延长手术时间， 同时 可形成肌间假道造成肌肉的损伤。  The pedicle screw technique has developed rapidly since its inception in the 1980s and has been widely used in the surgical treatment of spinal degeneration, vertebral spondylolisthesis, spinal stenosis, vertebral fracture, deformity, bone metastases, spinal instability and other diseases. . In recent years, small incision or percutaneous minimally invasive nailing has been gradually carried out and widely accepted by clinicians. However, in the case of small incision, it is still necessary to expose the small incision multiple times for acupuncture and distraction, which requires repeated exposures. The process of exposure not only prolongs the operation time, but also forms muscle damage caused by the intermuscular pseudo-track.
目前微创置钉主要是 Quadrant通道和 Sextant辅助下完成。 Quadrant通道也存在术中需要 反复暴露的问题， 而 Sextant 系统的叶片虽然可以起到类似的作用， 但叶片的安装和拔除都 比较困难， 而且以上两种系统的价格非常昂贵， 限制了它们的推广。  At present, minimally invasive nailing is mainly done with the aid of the Quadrant channel and Sextant. The Quadrant channel also has the problem of repeated exposure during surgery. Although the blades of the Sextant system can play a similar role, the installation and removal of the blades are difficult, and the above two systems are very expensive, which limits their promotion. .
发明内容 Summary of the invention
发明目的： 本发明的目的是在进行脊椎后路置钉操作后， 提供一种小切口撑开维持装置， 在置钉后置入该装置可以使切口维持撑开状态， 避免术中反复暴露， 为手术提供便利， 同时 节约手术时间， 避免软组织的损伤。  OBJECT OF THE INVENTION: The object of the present invention is to provide a small incision distraction maintaining device after performing a posterior screw placement operation, and placing the device after the nail is placed can maintain the incision in a distracted state to avoid repeated exposure during surgery. Convenient for surgery, while saving surgery time and avoiding soft tissue damage.
技术方案： 本发明所述的一种用于脊柱后路微创置钉小切口的撑开维持装置， 包括两个交 叉活动连接的拉钩条和弹簧， 所述拉钩条包括弧形臂和拉钩头， 两个拉钩条的弧形臂的连接 端通过销转动连接， 远端与拉钩头连接， 所述拉钩头一端与弧形臂平面垂直连接， 另一端向 内折弯， 端面设有月牙形凹槽， 所述弹簧设置在两个弧形臂之间。  Technical Solution: A distraction maintaining device for a minimally invasive small incision in the posterior spinal column of the present invention comprises two cross-linked detachable hook strips and a spring, the hooking strip comprising a curved arm and a hook head The connecting ends of the arc-shaped arms of the two hook strips are connected by a pin, and the distal end is connected with the hook head. One end of the hook head is perpendicularly connected to the plane of the curved arm, and the other end is bent inward, and the end surface is provided with a crescent shape. a slot, the spring being disposed between the two curved arms.
进一步地， 所述弹簧位于两个弧形臂之间靠近连接端位置处。  Further, the spring is located between the two curved arms at a position close to the connection end.
具体使用方法： 在小切口或者微创经皮置钉操作中， 一般是分多个小切口分别进行置钉操 作。 置钉完成以后， 再进行装连接棒， 撑开或者压缩等操作， 所以在操作过程中置钉后需要 反复暴露椎弓根钉的尾部， 本发明在置钉操作完成， 置钉拉钩未移除之前插入， 然后移除置 钉拉钩， 拉钩远端新月形凹陷设计可以轻易的卡在椎弓根钉尾部， 这样就可以维持切口的撑 开， 不需要反复暴露。 而弧形臂的内弯设计在拉钩和椎弓根钉尾部之间留下一定的空隙， 需 要再次暴露时可以轻易的置入置钉拉钩， 在操作完成以后可以直接拔除拉钩而不会造成组织 的损伤。  Specific use method: In the small incision or minimally invasive percutaneous nailing operation, the nailing operation is generally performed by a plurality of small incisions. After the nailing is completed, the connecting rod, the opening or the compression is performed, so that the tail of the pedicle screw needs to be repeatedly exposed after the nail is placed during the operation. The present invention is completed after the nailing operation is completed, and the nail hook is not removed. Inserted before, then remove the nail pull hook, the distal crescent recess design of the hook can be easily caught in the tail of the pedicle screw, so that the slit can be maintained open without repeated exposure. The curved shape of the curved arm leaves a certain gap between the hook and the pedicle nail tail. When it needs to be exposed again, the nail hook can be easily placed. After the operation is completed, the hook can be directly pulled out without causing tissue. Damage.
本发明与现有技术相比， 其有益效果是： （1 ) 操作简单省时， 容易掌握， 医生接受度好; ( 2 ) 价格便宜； （3 ) 可以明显降低反复暴露的次数， 缩短手术时间； （4 ) 可以减少组织损 伤。 Compared with the prior art, the invention has the following beneficial effects: (1) the operation is simple and time-saving, easy to grasp, and the doctor accepts well; (2) The price is cheap; (3) The number of repeated exposures can be significantly reduced, and the operation time can be shortened; (4) Tissue damage can be reduced.
