For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] This embodiment provides a microscopic intervertebral disc height measuring device, the structure of which is as follows Figure 1 , Figure 2 As shown, it includes a pliers handle 1, a pliers rod 2, a detection piece 3 and a scale 4. The pliers handle 1 is arranged at one end of the pliers rod 2, the detection piece 3 is arranged at the other end of the pliers rod 2, and the scale 4 is arranged on the pliers handle 1; when in use, the pliers handle 1 controls the opening and closing of the detection piece 3, and the opening and closing size of the detection piece 3 is displayed through the scale 4.

[0021] Based on the above structure, when the utility model is in use, the detection piece 3 is driven by the clamp rod 2 to pass through the slightly wound incision and enter the position to be tested, the detection piece 3 is controlled by the clamp handle 1 to detect the height of the intervertebral space, and the detection result is displayed on the scale 4 set on the clamp handle 1. The whole detection process is simple and has high accuracy.

[0022] In some embodiments of the present application, the pliers handle 1 includes a fixed pliers handle 11 and a movable pliers handle 12 . The fixed pliers handle 11 is fixedly connected to one end of the pliers rod 2 , and the movable pliers handle 12 is hinged to one end of the fixed pliers handle 11 close to the pliers rod 2 .

[0023] In this embodiment, the fixed clamp handle 11 supports the clamp rod 2, and the movable clamp handle 12 rotates relative to the fixed clamp handle 11 to drive the detection member 3 to measure the height of the intervertebral space. The clamp handle 1 is located outside the minimally invasive wound, which is convenient for medical staff to operate.

[0024] In some embodiments of the present application, a push-pull wire 6 is passed through the clamp rod 2 , one end of the push-pull wire 6 is movably connected to the movable clamp handle 12 , and the other end of the push-pull wire 6 is connected to the detection member 3 .

[0025] In this embodiment, when the movable clamp handle 12 rotates relative to the fixed clamp handle 11, it drives the push-pull wire 6 to move, and then the push-pull wire 6 drives the detection member 3 to move to measure the height of the intervertebral space.

[0026] In some embodiments of the present application, the detection member 3 includes two detection heads, and a connecting shaft 7 connected to the side wall of the clamp rod 2 is also provided inside the clamp rod 2. One end of the two detection heads extending into the clamp rod is connected to the push-pull wire 6 and is hinged to the connecting shaft 7.

[0027] Specifically, Figure 3 As shown, two push-pull wires 6 are provided, and one end of the two push-pull wires 6 is movably connected to the movable clamp handle 12 through a connecting piece. When the movable clamp handle 12 rotates relative to the fixed clamp handle 11, the two push-pull wires 6 will be driven to move along the axial direction of the measuring device, and then the two push-pull wires 6 will drive the two detection heads arranged at the other end thereof to move, thereby completing the measurement of the intervertebral space height.

[0028] In some embodiments of the present application, the detection head includes a connecting rod 32 and a probe 31 arranged at one end of the connecting rod 32 , and the other end of the connecting rod 32 is connected to the push-pull wire 6 and hinged to the connecting shaft 7 .

[0029] In this embodiment, the connecting rods 32 of the two detection heads are hinged to the clamp rod 2 through the connecting shaft 7. The two connecting rods 32 are respectively connected to a push-pull wire 6 near the connecting shaft 7. When the two push-pull wires 6 move left and right along the axial direction of the clamp rod 2 with the rotation of the movable clamp handle 12, they will drive the two detection heads to rotate relative to the connecting shaft 7, thereby realizing the opening and closing of the two detection heads. At this time, the probe 31 arranged at one end of the connecting rod 32 measures the height of the intervertebral space.

[0030] In some embodiments of the present application, the probe 31 is an arc-shaped protrusion.

[0031] In this embodiment, the probe 31 is configured as an arc-shaped protrusion, which can reduce the opening angle of the connecting rod 32 to avoid operational difficulties caused by the connecting rod 32 being opened too much, and can also prevent the edges of the detection head from damaging other tissues in the spine.

[0032] In some embodiments of the present application, the size of the two detection heads along the radial direction of the measuring device from closed to open is 6-16 mm, which can meet the requirements of measuring different intervertebral heights.

[0033] In some embodiments of the present application, one end of the scale 4 is fixedly connected to the movable clamp handle 12 , and a guide groove 5 matching with the scale 4 is provided on the fixed clamp handle 11 , and the scale 4 is inserted into the guide groove 5 .

[0034] In this embodiment, a guide groove 5 is provided on the fixed clamp handle 11, so that when the movable clamp handle 12 rotates relative to the fixed clamp handle 11, the movable clamp handle 12 can drive the scale 4 to slide stably on the fixed clamp handle 11, thereby displaying the opening and closing size of the detection head and completing the measurement of the intervertebral height.

[0035] In some embodiments of the present application, the length of the clamp rod 2 along the axial direction of the measuring device is 320-340 mm, and the diameter is 2.5-3.5 mm. The size of the clamp rod 2 and the detection piece 3 is small, which makes it convenient to extend the detection piece 3 and the clamp rod 2 into the appropriate position in the patient's body through a minimally invasive incision, thereby reducing the size of the wound and facilitating the patient's recovery.

[0036] The method for using the microscopic intervertebral disc height measuring device provided in this embodiment is as follows:

[0037] When in use, first close the two detection heads of the detection piece 3, extend the clamp rod 2 and the detection piece 3 to the position to be detected through a slightly wound incision, rotate the movable clamp handle 12 relative to the fixed clamp handle 11, and the movable clamp handle 12 drives the push-pull wire 6 to move along the axial direction of the measuring device, driving the two connecting rods 32 of the detection piece 3 to rotate along the connecting shaft 7 set at one end of the clamp rod 2 close to the detection piece 3, and then the two connecting rods 32 drive the two probes 31 to open until the probes 31 abut against the two vertebrae. In this process, when the movable clamp handle 12 rotates, it also drives the scale 4 to slide in the guide groove 5 on the fixed clamp handle 11, so as to display the opening size of the two probes 31 and complete the measurement of the intervertebral height.

[0038] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
