Description

Technical Field

[0001] The present invention belongs to the technical field of orthopedic medical devices, and in particular relates to a lumbar fusion device implantation device and a method of using the same. Background Art

[0002] When treating lumbar problems such as lumbar disc herniation, lumbar spinal stenosis, lumbar degenerative disease and recurrence of simple disc herniation, posterior lumbar fusion devices are often implanted for treatment. However, current fusion devices have poor fusion and stability, require screws to stabilize, are inconvenient to implant, and their safety is not guaranteed.

[0003] Authorization publication number "CN204600804U" records an expandable fusion device that can be safely and efficiently implanted and is conducive to restoring the physiological curvature of the lumbar spine. It is made of titanium alloy or PEEK material. The expandable fusion device is in the shape of a hollow rectangular block as a whole. Continuous holes are opened in the middle of the front view, left view and right view of the expandable fusion device, and an elliptical turn buckle is provided in the middle of the hole on the front view. It is easy to implant without driving screws. It is safe and convenient. The expandable fusion device can be expanded by turning the elliptical turn buckle 90° using medical tools. Efficient bone grafting and fusion can well restore the physiological curvature of the lumbar spine. The edges of the upward and downward surfaces of the expandable fusion device are both serrated. The serrated design can better prevent the expandable fusion device from sliding and increase stability.

[0051] As a preferred solution of the present invention, a method for using a lumbar fusion device implant comprises the following steps.

[0052] S1. After the personnel dissect the patient's waist muscles one by one, the personnel use the PLC controller to control and start the six-axis robot arm, so that the six-axis robot arm and the second connecting sleeve fixed at the top move, and the second connecting sleeve will drive the grinding device connected to the outside to make the grinding device move in the six-axis direction with the six-axis robot arm. After the patient's lumbar intervertebral disc is polished, the personnel use the first square connecting groove to drive the second connecting block to flip, and then the first connecting plate will drive the first connecting sleeve fixed at the top to move, so that the first connecting sleeve can reach the top of the micro-grinding device to move, and the micro-grinding device will perform a second grinding on the patient's lumbar intervertebral disc. After the grinding is completed, the personnel use the adjustment mechanism. When using the adjustment mechanism, the personnel move the two second support rods close to each other. Between the patient's lumbar intervertebral discs, the personnel then rotate the rotating twist to make the rotating twist drive the screw fixed on one end to rotate, and the screw will drive the adjustment slot on the surface to move, and the adjustment slot will drive the moving plate fixed on the surface to move when it moves, and the movement of the moving plate will slide on the surface of the limit rod, and the moving plate will also drive another second support rod fixed on the top when it slides, so that the other second support rod can move, and the two second support rods can support the patient's lumbar intervertebral discs, which makes it more convenient for personnel to install the fusion device, and the two planes of the fusion device have three degrees of height that can be adjusted by personnel, and it is guaranteed that the height will not be lost under a certain pressure. On the sagittal plane of the fusion device, the front is high and the back is low, and the upper and lower surfaces are °-°. The coronal plane direction of the fusion device is for the convenience of fusion device implantation and distraction operation during surgery.

[0053] S2. The limit rods are fixed to the inner walls of both sides of the adjustment groove by welding. The adjustment groove is used to accommodate the parts in the adjustment mechanism. When the screw rod rotates, it will drive the adjustment groove on the surface to move. When the adjustment groove moves, it will drive the moving plate fixed on the surface to move. The movement of the moving plate will slide on the surface of the limit rod, and when the moving plate slides, it will also drive another second support rod fixed on the top to move the other second support rod. The two second support rods are made of tough material. The two second support rods can support the patient's lumbar intervertebral disc, making the installation of the fusion device more convenient. One side end of the screw rod passes through one side inner wall of the adjustment groove and is fixedly connected to the circumferential surface of the rotating twist. Therefore, the person can drive the screw rod to rotate by rotating the rotating twist, so as to drive one of the second support rods to move by driving the parts in the adjustment mechanism.

[0054] Compared with the prior art, the present invention has the following beneficial effects:

[0055] 1. In this scheme, after the personnel dissect the patient's waist muscles one by one, the personnel use the PLC controller to control the start of the six-axis robot arm, so that the six-axis robot arm moves with the second connecting sleeve fixed at the top, and the second connecting sleeve will drive the grinding equipment connected to the outside, so that the grinding equipment moves in the six-axis direction with the six-axis robot arm. After the patient's lumbar intervertebral disc is polished, the personnel use it to pull the first square connecting groove to drive the second connecting block to flip, and then the first connecting plate will drive the first connecting sleeve fixed at the top to move, so that the first connecting sleeve can reach the top of the micro-grinding equipment to move, and the micro-grinding equipment will perform secondary grinding on the patient's lumbar intervertebral disc After polishing, the personnel use the adjustment mechanism. When using the adjustment mechanism, the personnel place the two second support rods close to the patient's lumbar intervertebral disc, and then the personnel rotate the rotating torque to drive the components in the adjustment mechanism. The components in the adjustment mechanism will drive another second support rod to move, so that the two second support rods can support the patient's lumbar intervertebral disc, which makes it more convenient for personnel to install the fusion device, and the two planes of the fusion device can be adjusted by personnel at three degrees, and ensure that the height is not lost under a certain pressure. On the sagittal plane of the fusion device, the front is high and the back is low, and the upper and lower surfaces are 6°. The coronal plane direction of the fusion device is for surgery, which is convenient for fusion device implantation and distraction operation.

[0056] 2. In this solution, the monitoring equipment can be adjusted by moving the T-shaped connecting plate set in the component mechanism. The specific adjustment position can be selected according to the angle at which the personnel pulls the T-shaped connecting plate. The monitoring equipment will monitor and record the operations performed by medical personnel during surgery.

[0057] 3. In this solution, when personnel need to limit the first fixing plate and the second fixing plate, the personnel can rotate the two first bolts so that the two first bolts are respectively threadedly connected to the opposite ends of the first fixing plate and the second fixing plate. As the personnel rotate the two first bolts, the two first bolts will respectively thread through the two first fixing plates and be threadedly connected to the upper and lower ends of the micro-grinding equipment, thereby achieving the limitation of the first fixing plate and the second fixing plate. At the same time, it is more convenient for personnel to adjust the first fixing plate and the second fixing plate. BRIEF DESCRIPTION OF THE DRAWINGS
