DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1

[0041] See also Figure 1-Figure 10 , the present invention provides the following technical solutions:

[0042] A spinal surgery auxiliary device, comprising:

[0043] A hydraulic oil tank 1, wherein the hydraulic oil tank 1 is filled with hydraulic oil;

[0044] A square mounting block 8, which is fixedly connected to the lower inner wall of the hydraulic oil tank 1;

[0045] Lifting mechanism, the lifting mechanism is provided with multiple groups, each group of lifting mechanisms includes a lower sliding hole 2, an upper sliding hole 3, a lower hydraulic rod 4, an upper hydraulic rod 5, a spring slot 6, a first spring 7, a limit card slot 9, a guide block 11 and a limit card block 13. The lower sliding hole 2 is opened on the lower inner wall of the hydraulic oil tank 1, the upper sliding hole 3 is opened on the upper inner wall of the hydraulic oil tank 1, the lower hydraulic rod 4 is slidably connected in the lower sliding hole 2, the upper hydraulic rod 5 is fixedly connected to the upper end of the lower hydraulic rod 4 and slides in the upper sliding hole 3, the spring slot 6 is opened on one side end of the lower hydraulic rod 4, the first spring 7 is fixedly connected to the upper inner wall of the spring slot 6, the limit card slot 9 is opened on one side end of the square mounting block 8, the guide block 11 is slidably connected in the limit card slot 9, and the limit card block 13 is fixedly connected to one side end of the first spring 7.

[0046] In a specific embodiment of the present invention, the tool table 36 is loaded with various tools required for spinal surgery. The lower hydraulic rod 4 is used to support the tool table 36. The lower hydraulic rod 4 and the upper hydraulic rod 5 are integrally formed. Hydraulic oil is provided in the hydraulic oil tank 1, and a lower sliding hole 2 and an upper sliding hole 3 are respectively provided at the upper and lower ends of the hydraulic oil tank 1 to provide sliding space for the lower hydraulic rod 4 and the upper hydraulic rod 5. The first spring piece 7 is an elastic metal sheet that is bendable and has a certain toughness. The limit block 13 and the guide block 11 both have a slope with a forty-five degree angle on one side. During the operation, when the operator needs to use one of the tools, the corresponding lower hydraulic rod 4 can be pulled downward. Since the cross-section of the lower hydraulic rod 4 is larger than that of the upper hydraulic rod 5, and when the lower hydraulic rod 4 is pulled down, the lower hydraulic rod 4 is arranged in the hydraulic oil tank 1 and the length of the upper hydraulic rod 5 is arranged in the hydraulic oil tank 1 is increased, so that the total volume of the lower hydraulic rod 4 and the upper hydraulic rod 5 arranged in the hydraulic oil tank 1 is reduced, thereby reducing the oil pressure in the hydraulic oil tank 1, and the pressure difference generated by the oil pressure forms a pulling force on the upper surfaces of the remaining multiple lower hydraulic rods 4, and the multiple lower hydraulic rods 4 that are not needed are pulled upward to leave the surgical height without affecting the surgery. When the downwardly sliding lower hydraulic rod 4 slides down under the limiting block 13 and contacts the upper end of the square mounting block 8, the contact surface of the limiting block 13 and the square mounting block 8 is an inclined surface, and the square mounting block 8 squeezes the limiting block 13 to cause the first spring sheet 7 to bend to a certain extent, so that the limiting block 13 fits the side surface of the square mounting block 8 and Continue to slide downward. When the limit card block 13 slides to the limit card slot 9, the first spring piece 7 that was squeezed and deformed before rebounds, and the limit card block 13 is stuck in the limit card slot 9 to complete the fixation of the lower hydraulic rod 4, so that the lower hydraulic rod 4 will not slide back to its original position upward, which is convenient for the operator to take the surgical tools. The remaining lower hydraulic rods 4 are also fixed at the upper end due to the oil pressure, which does not affect the operation. When the tools used in the operation need to be replaced, the lower hydraulic rod 4 can be pulled downward continuously. At this time, the limit card block 13 contacts one side end of the guide block 11, and the guide block 11 also squeezes the limit card block 13 to deform the first spring piece 7. When the limit card block 13 slides to the lower end of the guide block 11, the first spring piece 7 rebounds and contacts the lower end of the guide block 11. The lower hydraulic rod 4 is pushed upward, and the limiting card block 13 drives the guide block 11 to slide upward together. When the guide block 11 slides to the top of the limiting card slot 9, the limiting card block 13 in contact with the inclined surface of the guide block 11 under the action of the thrust will squeeze the first spring piece 7 to deform it again, until the limiting card block 13 slides to one side of the guide block 11. When the limiting card block 13 continues to move upward, it is out of contact with the guide block 11, and the limiting card block 13 also slides out of the limiting card slot 9 to release the fixed restriction on the lower hydraulic rod 4, the lower hydraulic rod 4 can be pushed back to its original position, and the remaining surgical tools can be replaced again. The used tools are higher than the operating area. At this time, the nurse can disinfect the used surgical tools on the tool table 36.After the treatment is completed, it can be installed again on the tool table 36, so that when the surgeon changes the surgical tools, he can take the surgical tools that have been prepared on the lifting mechanism by himself, saving the time of tool standby and personnel transfer. When the surgical staff is insufficient, the tool transfer or standby will not be slow, thus delaying the surgical process. The spare surgical tools are located at the upper end of the surgical area, which will not affect the surgical process of the surgeon.

[0048] In this embodiment: the spring plate 16 is supported by the first return spring 17, and the first return spring 17 provides an upward pulling force for the lower hydraulic rod 4. When none of the lower hydraulic rods 4 is pulled downward, multiple lower hydraulic rods 4 are adjusted by the elastic force of the first return spring 17 so that multiple lower hydraulic rods 4 are in the same horizontal plane. When one of the lower hydraulic rods 4 is pulled downward, the first return spring 17 is stretched until the lower hydraulic rod 4 is fixed by the limit block 13. When the limit block 13 is out of contact with the limit slot 9, the pulling force of the first return spring 17 pulls the lower hydraulic rod 4 back to its original position. The sealing ring 15 is arranged at the connection between the upper sliding hole 3 and the upper hydraulic rod 5 and at the connection between the lower hydraulic rod 4 and the lower sliding hole 2, and is used for sealing to prevent leakage of hydraulic oil in the hydraulic oil tank 1.
