Problems solved by technology

The fixed frame is fixed by the rectangular groove and the fixing screw on the ring frame. Although this connection method is firmly positioned, it is cumbersome to use and inconvenient to adjust; and the patent ZL00257617.7 is based on the patent ZL96229730.5. The connection structure between the frame and the draw hook fixer has been improved, that is, rectangular teeth are evenly arranged on the periphery of the ring frame, and two cylindrical pins are arranged in the rectangular grooves on the frame, and the gap between the frame and the frame is passed The above-mentioned two cylindrical pins are engaged with the rectangular teeth around the ring frame. Although this structure is more convenient to use than the prior patent ZL96229730. Infect the patient's wound; at the same time, the fixed frame only eliminates four degrees of freedom on the ring frame, and the rotation degree of freedom of the fixed frame on the horizontal plane is not eliminated, so the pull hook fixer often deflects during use, resulting in unstable retraction , is not conducive to the normal operation
