[0002] In abdominal surgery, retractor devices are essential medical instruments. Their function is to pull apart the skin, muscles, internal organs, and other tissues around the surgical incision, thereby providing a clear surgical field and facilitating surgical procedures. Currently, there are various types of abdominal surgical retractor devices used clinically, mainly including manual retractors and automatic retractors.
[0003] Manual retractors require manual operation by medical staff, which not only increases their workload but also makes it difficult to maintain stable traction force. Hand tremors can easily affect the stability of the surgical field, and additional medical staff are needed, wasting human resources. While automatic retractors can achieve automatic traction, most existing automatic retractors have relatively simple telescopic structures with limited telescopic range and precision, making them difficult to adapt to different surgical sites and needs. This results in insufficient exposure of the surgical field, affecting the convenience and safety of the surgical procedure.

[0032] By adopting the above technical solution, the adjustable mounting base can achieve stable installation and initial position adjustment of the device, and the column (5) provides a supporting foundation for the range adjustment structure. The sliding fit between the sleeve column (6) and the column (5), combined with the threaded connection between the screw two (23) and the threaded channel (22) of the column (5), under the drive of the motor two (12), the rotation of the screw two (23) can drive the sleeve column (6) to move up and down along the column (5), thereby realizing the height adjustment of the adjusting seat (9) and changing the vertical working position of the pulling member.

Moreover, the meshing transmission method of the gear and the toothed teeth (27) has high transmission accuracy and can accurately control the moving distance of the U-shaped frame (11), thereby improving the position adjustment accuracy of the traction component and ensuring accurate exposure of the surgical field.
[0039] The present invention is further configured as follows: the angle adjustment structure includes a mounting shell (15) and a rotating rod (16), the rotating rod (16) is located inside the mounting shell (15) and both ends of the rotating rod (16) pass through the front and back of the mounting shell (15) and are rotatably connected; a worm gear (30) is provided in the middle of the rotating rod (16), and support plates (29) are provided on both sides of the worm gear (30); a convex plate is provided at the bottom of the mounting shell (15); the worm gear (30) is provided with a matching worm (28), the worm (28) is vertically arranged, the bottom end of the worm (28) is rotatably connected to the convex plate, and its top end passes through the mounting shell (15) and is provided with a motor (14); the support plate (29) is detachably connected to the mounting plate (17).
