Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

The utility model provides a technical solution: as shown in Figures 1-4, in this embodiment, a traction frame for hand and foot microsurgery includes an arc-shaped pad 1, and the top of the arc-shaped pad 1 is fixedly connected with a fixed Frame 2, a sleeve 3 is fixedly connected to the inside of the fixed frame 2, a moving plate 4 is slidingly connected to the inside of the sleeve 3, a drawbar 5 is fixedly connected to one side of the moving plate 4, and a pull hook 6 is fixedly connected to one end of the drawbar 5 , the other side of the moving plate 4 is rotatably connected with a driving rod 7, the other end of the driving rod 7 penetrates the sleeve 3 and extends to the outside of the sleeve 3, and one end of the driving rod 7 extending to the outside of the sleeve 3 is fixedly connected with a driving handle. , a locking assembly 8 for one-way locking of the driving rod 7 is provided inside the fixed frame 2, and a torsion spring 9 for resetting the driving rod is provided on one side of the moving plate 4;

Through the setting of the retractor hook 6, the traction bar 5 can be connected to the wound, and the pulling of the operating handle by the hand can drive the pulling of the driving rod 7, and then the movable plate 4 can drive the traction bar 5 and the retracting hook 6 for pulling. This creates traction work;

Through the setting of the locking component 8, the pulled driving rod 7 can be locked in one direction to ensure the stability of its traction, and there is no need for manual locking work. It has a self-locking function and improves the function of the traction frame. sex and practicality.
