[0035] Working principle:

[0036] When the device is used to assist in surgery in the minimally invasive surgery of intervertebral disc herniation, the clamping support bracket 11 on one side of the bearing support plate 1 is first clamped and supported by the elastic support structure of the upper and lower clamping rubber pads 18 and 19, and the incision layer on one side of the intervertebral disc herniation is clamped and supported. The structure and material properties of the upper and lower clamping rubber pads 18 and 19 can reduce the damage caused by clamping the skin layer, and the bracket protective rubber pad 25 provides a protective effect for reducing damage between the bottom of the clamping support bracket 11 and the subcutaneous tissue. After clamping the skin layer on one side, the other side of the skin layer is clamped and positioned. After the bilateral skin layer is clamped and positioned, the lateral adjustment rod 9 is slidably connected in the lateral adjustment slot 3 through the positioning and clamping sliding assembly structure between the sliding limiting block 14 and the distance sliding adjustment slot 15. According to the actual operation situation, the distance of the lateral adjustment rod 9 in the lateral adjustment slot 3 is adjusted to achieve appropriate adjustment of the distance between the clamped and expanded incision of the device, and the distance adjustment fastening nut 23 and the distance adjustment fastening bolt 17 are used to adjust the state of the lateral adjustment rod 9 in the lateral adjustment slot 3. The adjustment state is screwed to ensure that the clamping and expansion of the bilateral skin layer of the device can be more stable. The middle sliding adjustment block 8 in the middle adjustment slot 2 is connected through the sliding butt joint structure between the positioning and clamping sliding block 12 and the positioning and clamping sliding slot 5, and the adaptive sliding connection structure between the positioning and adjusting sliding block 13 and the positioning and adjusting sliding slot 6. According to the use requirement, the longitudinal directional displacement adjustment is made so that the center sleeve 10 can be located at the incision position required for minimally invasive surgery. The center sleeve 10 is used for the surgical tool to pass through the minimally invasive surgery to facilitate the minimally invasive surgery at the specified position. The elastic rubber ring 16 is provided so that the external minimally invasive surgical tool can be more conveniently inserted into the elastic rubber ring 16 after the device expands the skin on both sides of the surgical position. The elastic rubber ring 16 has the effect of elastic deformation due to its structural characteristics, can better protect various specifications of surgical equipment from shaking and other conditions during normal use, and can provide maximum surgical protection for the patient. The adjustment of the middle sliding adjustment block 8 in the middle adjustment slot 2 can be achieved through the adaptive threaded connection structure between the positioning and fastening nut 22 and the positioning and fastening bolt 21. The multi-stage adjustable design of the device with the positioning and fastening structure enables the device as a whole to meet various use requirements in the use of minimally invasive surgery of intervertebral disc herniation, effectively enriching the overall functionality, and replacing the combination of various auxiliary surgical equipment in minimally invasive surgery of intervertebral disc herniation, which is more convenient and stable.
