一种融合器把持器械A fusion device holding instrument

技术领域technical field

本申请涉及医疗器械领域,特别是涉及一种融合器把持器械。The present application relates to the field of medical devices, in particular to a fusion device holding device.

背景技术Background technique

TLIF(Transforaminal Lumbar Interbody Fusion)是指经椎间孔入路腰椎体间融合术。由于是从患者背部椎管更侧面的中线切口进入,这一术式大大降低了手术中的肌肉剥离数量,而且TLIF可以提供前柱的支撑和稳定,重建相应节段的正常解剖曲度,从而维持或恢复腰椎整体的生理曲度。TLIF (Transforaminal Lumbar Interbody Fusion) refers to transforaminal lumbar interbody fusion. Since it is entered from the midline incision on the side of the spinal canal on the back of the patient, this surgical method greatly reduces the amount of muscle stripping during the operation, and TLIF can provide support and stability of the anterior column and reconstruct the normal anatomical curvature of the corresponding segment, thereby Maintain or restore the overall physiological curvature of the lumbar spine.

而目前用于TLIF手术的融合器及其把持器不能使融合器实现植入角度可调,导致最终的支撑位置不贴合终板,稳定性差。有的医生术中通过往复摆动把持器,或敲击融合器末端,以便使融合器到达理想的植入位置。把持器的往复摆动或敲击融合器末端易对神经根及硬膜囊造成伤害,而且使得TLIF手术变得更加复杂。另外,由于锥体终板为凹面,两终板中心间隙大,外缘间隙小,对于高度大于宽度的融合器,以宽度方向通过终板外缘的间隙,更易植入融合器,然而融合器置入椎间后需要旋转90°放正,此时可能造成融合器相对融合器把持器械的转动,造成把持松动,滑丝。However, the fusion device and its holder currently used in TLIF surgery cannot allow the fusion device to achieve an adjustable implantation angle, resulting in that the final support position does not fit the endplate and the stability is poor. Some doctors swing the handle back and forth during the operation, or tap the end of the fusion device so that the fusion device can reach the ideal implantation position. The back-and-forth swing of the gripper or knocking on the end of the fusion device can easily cause damage to the nerve root and dural sac, and make the TLIF operation more complicated. In addition, because the endplates of the cone are concave, the center gap between the two endplates is large and the gap between the outer edges is small. For a cage whose height is greater than its width, it is easier to insert the cage through the gap between the outer edges of the endplates in the width direction. After being inserted into the intervertebral space, it needs to be rotated 90° to put it right. At this time, the fusion cage may rotate relative to the fusion cage holding device, resulting in loosening of the grip and slipping of the wire.

有鉴于此,如何提供一种针对在经椎间孔入路腰椎体间融合术中,实现融合器植入角度可调,且把持稳定的把持器械,即为本发明待解决的技术问题。In view of this, how to provide a holding instrument with adjustable implantation angle and stable holding for transforaminal lumbar interbody fusion is the technical problem to be solved in the present invention.

Opening effect, improve the patient's physiological bending recovery effect. Clamping and threaded connection are used to fix and place the fusion cage, without over-tightening the thread to cause the risk of slippage, and at the same time prevent the thread from loosening during use, reducing the risk of the fusion cage being unable to be straightened after being implanted in the intervertebral space, especially for some with a width smaller than Due to the concave surface of the cone endplate, the middle gap between the two endplates is large and the outer edge gap is small. The doctor puts the fusion cage vertically in the intervertebral space, and then rotates it 90° to place it horizontally. , because there is no field of view between the vertebrae, the rotation state of the fusion device in the intervertebral area cannot be effectively determined, and thread slippage and loosening may occur when the rotation is 90°. The grasping arm of the embodiment of the present invention limits the axis of the fusion device relative to the fusion device holder Rotating in the opposite direction can clarify the state of the fusion cage in the intervertebral space, and can effectively prevent slippage or loosening of the fusion cage. It has the advantages of stable holding, safety and effectiveness.

Clamping and threaded connection are used to fix and place the fusion cage, without over-tightening the thread to cause the risk of slippage, and at the same time prevent the thread from loosening during use, reducing the risk of the fusion cage being unable to be straightened after being implanted in the intervertebral space, especially for some with a width smaller than Due to the concave surface of the cone endplate, the middle gap between the two endplates is large and the outer edge gap is small. The doctor puts the fusion cage vertically in the intervertebral space, and then rotates it 90° to place it horizontally. , because there is no field of view between the vertebrae, the rotation state of the fusion device in the intervertebral area cannot be effectively determined, and thread slippage and loosening may occur when the rotation is 90°. Axial rotation can clarify the state of the fusion cage in the intervertebral area, and can effectively prevent slippage or loosening of the fusion cage. It has the advantages of stable holding, safety and effectiveness.

综上,本申请有效克服了现有技术中的种种缺点而具高度产业利用价值。To sum up, the present application effectively overcomes various shortcomings in the prior art and has high industrial application value.
