Abstract
The utility model discloses an implantation device of interbody fusion cage, including supporting rod, locking lever, the fixed grip block that sets up of one end of supporting rod, the centre gripping groove is seted up to the supporting rod, and the locking lever slides and sets up in the centre gripping groove, and the locking groove is seted up respectively to the upper portion and the bottom of supporting rod, and the inslot slides and sets up the locking plate, and the upper portion and the bottom of locking lever set up respectively with the corresponding locking slope of locking plate, the bottom sliding connection of locking slope and locking plate. The utility model aims at providing an implantation device which can assist in pulling out a sealing device arranged on an intervertebral fusion device.
Description
Technical Field
The utility model relates to a medical instrument especially relates to an implantation device of interbody fusion cage.
Background
The spine is a support column of a body and is composed of vertebrae and intervertebral discs, and the intervertebral discs can play a role in loading and shock absorption in the process of spinal motion. When pathological changes such as degeneration, trauma and the like occur to the spine, the pathological intervertebral discs are often required to be removed, but interbody bone fusion is usually required to maintain the physiological functions of the spine. At present, the autogenous bone combined interbody fusion cage is the main fusion mode. The bone grafting material is mainly autogenous bone such as vertebral plate, articular process and the like cut in the operation, and the autogenous bone is trimmed into bone fragments and then packed into the interbody fusion cage.
The existing commonly used interbody fusion cage is generally designed to be provided with an upper opening and a lower opening, the middle of the interbody fusion cage is communicated with the upper opening and the lower opening, and the middle of the interbody fusion cage is filled and compacted by broken bone blocks until the upper surface and the lower surface of the interbody fusion cage slightly bulge out, so that the interbody fusion cage can be better contacted with cartilage end plates of adjacent vertebral bodies, and the long-term interbody fusion cage is favorable for. However, in the process of driving the fusion cage into the intervertebral space, in the process of extruding the cartilage endplate and the fusion cage, the broken bone blocks which are expanded from the upper surface to the lower surface are often scattered around the dural sac and the nerve roots, and if the broken bone blocks cannot be found and taken out in time, the broken bone blocks can clamp and press the nerve roots or the dural sac, so that the nerve function recovery of a patient is influenced. Therefore, a novel interbody fusion cage is designed, the novel interbody fusion cage is provided with sealing devices at the upper end and the lower end in a sliding manner, extrusion of broken bone blocks can be prevented, but the interbody fusion cage needs to be pulled out of the sealing devices after being implanted into a human body, otherwise, the interbody fusion cage can influence the bone grafting fusion between the vertebral bodies of a patient.
Disclosure of Invention
Utility model purpose: the utility model aims at providing an implantation device which can assist in pulling out a sealing device arranged on an intervertebral fusion device.
The technical scheme is as follows: an implantation device of interbody fusion cage, including supporting rod, locking lever, the fixed grip block that sets up of one end of supporting rod, the centre gripping groove is seted up to the supporting rod, the locking lever slides and sets up in the centre gripping groove, and the locking groove is seted up respectively to the upper portion and the bottom of supporting rod, the inslot slides and sets up the locking plate, the upper portion and the bottom of locking lever set up the locking slope corresponding with the locking plate respectively, the bottom sliding connection of locking slope and locking plate.
Furthermore, a pushing block is fixedly arranged at the other end of the clamping rod, an operation through groove for operation is formed in the pushing block, a screw rod is arranged in the operation through groove, and the other end of the locking rod extends into the operation through groove and is in threaded connection with the screw rod.
Further, the included angle between the locking slope and the horizontal plane is 3-15 degrees.
Has the beneficial effects that: compared with the prior art, the utility model, have following advantage: because the locking slope that corresponds with the locking plate is set up at the locking lever, when the relative holding rod of locking lever slided, the locking plate can reciprocate along the locking groove to realize that the locking plate can form spacing relation with the closing device on the interbody fusion cage after the locking, the doctor of being convenient for pulls out the closing device on the interbody fusion cage.
