[0031] It includes a fixed groove 21 fixedly installed on the upper end of the base 11, sliding grooves 22 arranged on both sides of the fixed groove 21, an elastic groove 23 slidably installed inside the sliding groove 22, extension grooves 24 respectively arranged in the middle of the bottom end of the fixed groove 21 and in the middle of the top end of the elastic groove 23, an extension piece 25 slidably installed inside the extension groove 24, a push-pull plate 26 arranged at one end of the extension piece 25, a pulling hole 27 arranged on the outer side of the bottom end of the fixed groove 21 and the outer side of the top end of the elastic groove 23, and a pulling hook 28 inside the pulling hole 27 for disassembly and connection.
[0032] The tail section of the lens channel 12 is tilted upward by 15-30 degrees, which expands the visual angle and facilitates observation by medical staff; a transparent protective cover 121 is provided at the end of the lens channel 12, which can isolate the lens inside the lens channel to avoid blood contamination.
[0033] The inlets of the water inlet channel 13 and the water outlet channel 14 are respectively fixedly connected to the water inlet joint 131 and the water outlet joint 141, so as to facilitate the connection of the external water inlet mechanism and the liquid pumping assembly.
[0034] The sliding grooves 22 are provided in multiple groups, and the sliding grooves 22 are vertically arranged on both sides of the fixed groove 21; the elastic grooves 23 move in a direction perpendicular to the fixed grooves 21. It is ensured that the elastic grooves 23 are restricted by the sliding grooves 22 at any position, so that the elastic grooves 23 can move along the sliding grooves 22 when the fusion device enters and is stretched.
[0035] The other end of the extension piece 25 is in an arc-shaped structure; it can extend the channel formed by the fixing groove 21 and the elastic groove 23, and further extend the channel to the insertion position, so that the fusion device can enter the predetermined position more easily, thereby improving the success rate of fusion device insertion; an observation groove 251 is provided in the middle of the extension piece 25, which is convenient for medical staff to observe the insertion of the fusion device and to intuitively understand the insertion depth of the extension piece; the size of the extension piece 25 is adapted to the size of the extension groove 24.

[0037] The hook 282 at the end is made of elastic metal material. When the device is clamped by muscles or other circumstances and is difficult to be taken out, the hook 28 can be used to clamp into the pulling hole 27 for dragging to assist in taking out the device.
[0038] The extension slot 24 further includes a push-pull slot 241 disposed at the left side of the bottom end of the fixed slot 21 and the left side of the top end of the elastic slot 23. The push-pull slot 241 communicates with the extension slot 24. The push-pull plate 26 is slidably connected inside the push-pull slot 241. The top surface of the push-pull plate 26 on the fixed slot 21 is flush with the inner wall of the fixed slot 21.

[0041] The minimum size of the channel formed by the fixed slot 21 and the elastic slot 23 of the present utility model is adapted to the inner diameter of the existing cylindrical insertion channel when compressed.
[0042] The outer surfaces of the fixed slot 21 and the elastic slot 23 of the present utility model are smooth, and the corners are all smoothly transitioned.
[0043] Embodiment 3
[0044] Working principle: When using this device, it needs to cooperate with the existing cylindrical insertion channel. First, perform a conventional minimally invasive spinal fusion endoscopic surgery to open a surgical channel at the site where the fusion device needs to be inserted in the patient, and use the existing cylindrical insertion channel to fix the channel. At this time, insert this device along the cylindrical insertion channel, and insert the lens into the lens channel 12.
[0045] Under the cooperation of the lens field of view, judge the insertion depth of this device. When the insertion depth of this device reaches the insertion depth of the cylindrical insertion channel, simultaneously connect the external water inlet mechanism and the liquid extraction assembly to the water inlet joint 131 and the water outlet joint 141 respectively. Then remove the cylindrical insertion channel, so that the human muscles wrap this device. At this time, observe the position of the device through the lens field of view. When the device does not reach the appropriate position, adjust the depth of the device through the push-pull device to make the device reach the appropriate position. At this time, the fusion device can be inserted. Since the outer sides of the fixed slot 21 and the elastic slot 23 will be squeezed by the human muscles after the device is inserted into the human body, the channel formed by the fixed slot 21 and the elastic slot 23 is in the minimum size state.
[0046] When the fusion device is inserted, the position of the insertion port needs to be separated by an external force (with the help of surgical forceps or other instruments) to a size that allows the fusion device to enter. Then, the fusion device is inserted. When the fusion device enters the channel formed by the fixing groove 21 and the elastic groove 23, the existing method of pushing the fusion device is used, and the fusion device is pushed deeper into the channel with the help of medical devices. During this process, the inserted fusion device continuously pushes the channel formed by the fixing groove 21 and the elastic groove 23 open to a size suitable for the fusion device to pass through under the action of the external force, so that the fusion device continuously advances along the channel. After the fusion device passes through, the extrusion force will press the fixing groove 21 and the elastic groove 23 together again to prevent the fusion device from slipping off. At this time, the camera is used to observe whether the fusion device leaks out of the channel formed by the fixing groove 21 and the elastic groove 23, so as to judge the insertion depth of the fusion device. When it is observed that the fusion device leaks out of the channel, under the cooperation of the camera field of view, the push-pull plate 26 is pushed to make the extension piece 25 extend outwards, lengthening the length of the channel formed by the fixing groove 21 and the elastic groove 23. With the assistance of the camera field of view, the channel formed by the extension piece 25 is made closer to the insertion position. At this time, the fusion device is continuously pushed forward to make it easier for the fusion device to enter the predetermined position. During the insertion process, due to the action of the external force, bleeding may occur in the patient's body. At this time, it is necessary to cooperate with the external water inlet mechanism and the water inlet channel
[0047] 13. Insert the cleaning liquid to wash the blood stains, and at the same time cooperate with the external liquid extraction component and the water outlet channel 14 to export the waste liquid to prevent the blood stains from blocking the field of view and affecting the insertion of the fusion device;
[0048] After the fusion device is inserted, the push-pull plate 26 is pulled to retract the extension piece 25. At this time, the outside of the fixing groove 21 and the elastic groove 23 is squeezed by the human muscle, so that the channel formed by the fixing groove 21 and the elastic groove 23 is in the minimum size state. Then, the camera is withdrawn from the camera channel 12, and then the hook 282 of the drag hook 28 is hooked into the pulling hole 27, and then the device is slowly dragged outwards to remove the device and complete the operation.
