Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an adjustable implant device for a visual intervertebral fusion device with a built-in lens. Background Art

[0002] When performing spinal fusion, surgeons usually first remove the intervertebral disc at the diseased location, and then insert a fusion cage into the intervertebral disc space to replace the removed intervertebral disc; the shape of the fusion cage matches the shape of the intervertebral disc space to facilitate insertion into the intervertebral disc space; the fusion cage is filled with fillers such as bone, tissue, cells, and drugs to help bones grow from both sides of the fusion cage into the fusion cage, ultimately achieving fixation of the fusion cage.

[0003] However, the current fusion device implantation channel is a hollow cylindrical channel with a fixed channel size that cannot be adjusted according to the size of the fusion device. The inner wall is smooth, and the fusion device is easy to fall off during implantation. In addition, the fusion device is easy to get stuck at the end of the channel during implantation, making it difficult to implant smoothly. At the same time, the existing fusion device requires the assistance of an independent endoscopic device during the implantation process. During surgery, the lens needs to be independently controlled, which is complicated to use. At the same time, the existing fusion device channel must serve as both a fusion device implantation channel and an endoscope channel when in use. When in use, the fusion device is easily affected by the endoscope extension line, making it difficult to use.

[0004] Therefore, in order to solve the above technical problems, the present invention provides a visual intervertebral fusion cage adjustable implant device with a built-in lens. Utility Model Content

[0032] The inlets of the liquid inlet channel 14 and the liquid outlet channel 15 are fixedly connected to a water inlet connecting pipe 141 and a water outlet connecting pipe 151 respectively.

At the same time, when the extension plate 242 is extended, the fusion device implantation channel formed by the lower groove body 21 and the upper groove body 23 can be extended, and the channel can be further extended to the implantation position, making it easier for the fusion device to enter the predetermined position, thereby improving the success rate of implantation of the fusion device; an observation groove 245 is provided in the middle of the extension plate 242; it is convenient for medical staff to observe the implantation status of the fusion device and to intuitively understand the implantation depth of the extension piece; the size of the extension plate 242 is adapted to the size of the extension groove 241.

[0044] The external display screen of the present invention is an endoscope display device of the electronic fiberscope, which can display the field of view collected by the electronic fiberscope on the display screen.

[0045] The upper trough body 21 and the lower trough body 23 of the present invention have smooth surfaces, and the corners are all smoothly transitioned.

[0046] Example 3

[0047] Working principle: When using this device, it is necessary to cooperate with the existing cylindrical implantation channel. It is necessary to first perform a conventional intervertebral fusion device endoscopic minimally invasive surgery, open a surgical channel at the site where the patient needs to implant the fusion device, and use the existing cylindrical implantation channel to expand and fix the channel. At this time, implant this device along the cylindrical implantation channel, and connect the transmission connector at the head end of the electronic fiberscope to the connection cable connector of the external display screen. Turn on the electronic fiberscope and start working. At this time, the implantation depth of this device is judged with the cooperation of the lens field of view. When the implantation depth of this device reaches the implantation depth of the cylindrical implantation channel, When the device is inserted into the human body, the external water inlet mechanism and the liquid extraction assembly are connected to the water inlet connector 131 and the water outlet connector 141 respectively; then the cylindrical implantation channel is removed, so that the human body muscles cover the device. At this time, the position of the device is observed through the lens field of view of the electronic fiberscope 12. If the device does not reach the appropriate position, the depth is adjusted by the push-pull device until the device reaches the appropriate position. At this time, the fusion device can be implanted. After the device is implanted into the human body, the outer sides of the fixing groove 21 and the elastic groove 23 will be squeezed by the human body muscles, so that the channel formed by the fixing groove 21 and the elastic groove 23 is in the smallest size state;

[0048] Therefore, when the fusion device is implanted, the implantation port needs to be separated by external force (with the help of surgical forceps or other instruments) to a size that satisfies the entry of the fusion device, and then the fusion device is implanted into the fusion device channel formed by the upper trough body 21 and the lower trough body 23. After the fusion device enters the channel, the existing method of pushing the fusion device is adopted, and the fusion device is pushed deep into the channel with the help of medical equipment. During this process, the implanted fusion device continuously pushes the channel formed by the lower trough body 21 and the upper trough body 23 to a size that is suitable for the passage of the fusion device under the action of external force, so that the fusion device is continuously advanced along the channel. After the fusion device passes, the extrusion force will re-press the lower trough body 21 and the upper trough body 23. The body 23 is pressed together to prevent the fusion device from slipping; at this time, the fusion device is observed through the lens field of view of the electronic fiberscope 12 to see whether it leaks out of the channel formed by the lower trough body 21 and the upper trough body 23, thereby judging the implantation depth of the fusion device. After the fusion device is observed to leak out of the channel through the observation groove 245, the adjustment block 244 is pushed to extend the extension plate 242 outward with the cooperation of the lens field of view of the electronic fiberscope 12, thereby lengthening the length of the channel formed by the lower trough body 21 and the upper trough body 23. With the help of the lens field of view of the electronic fiberscope 12, the channel formed by the extension plate 242 is brought closer to the implantation position; at this time, the fusion device is continued to be pushed to make it easier to enter the predetermined position;

[0049] During the implantation process, the patient may bleed due to external forces. In this case, it is necessary to use the external water inlet mechanism in conjunction with the liquid inlet channel 14 to inject cleaning liquid to flush the blood stains on the lens surface of the electronic fiberscope 12 and the surface of the lighting lamp. At the same time, the waste liquid is discharged through the external liquid extraction component in conjunction with the liquid discharge channel 15 to prevent the blood stains from blocking the field of view and affecting the implantation of the fusion device.

[0050] After the fusion device is implanted, the extension plate 242 is retracted by pulling the adjustment block 244. At this time, the outer sides of the lower trough body 21 and the upper trough body 23 are squeezed by the human body muscles, so that the channel formed by the lower trough body 21 and the upper trough body 23 is in the minimum size state, and then the hook 262 of the puller 26 is inserted into the pulling hole 25, and then the device can be taken out by slowly dragging it outward. After taking out the device, disconnect the transmission connector at the head end of the electronic fiberscope from the connection line connector of the external display screen, and at the same time disconnect the water inlet connector 131 and the water outlet connector 141 from the external water inlet mechanism and liquid extraction component, clean and disinfect the instruments, and complete the operation.
