[0032] The disassembly assembly 3 includes an annular sleeve 31, the annular sleeve 31 is provided with an opening 32, and limiting grooves 33 are provided on both sides of the opening 32. A push plate 35 is slidably connected in the limiting groove 33. The push plate 35 is arranged in an inverted T shape. The bottom of the push plate 35 is slidably connected to the limiting groove 33. A spring 34 is fixedly connected between the top of the push plate 35 and the opening 32. The spring 34 is used to reset the push plate 35.
[0033] The clamping needle 5 is connected to a limiting component 9, and the limiting component 9 is used to limit the universal needle clamp 4.
[0034] The universal needle holder 4 includes two universal heads 41 arranged opposite to each other. The universal heads 41 are arranged in the shape of long arc plates. The arc shape fits the bone shape better and is convenient for embracing oblique broken bones. Different types of universal heads 41 can be selected according to fracture sites of different sizes to improve the fit, enhance the stability of positioning, clamping and reduction, and make it easier to operate. A through hole 43 is opened in the middle of the universal head 41, and a connecting ring 42 is fixed at the through hole 43. The connecting ring 42 is in a circular shape and is fixedly connected to the middle of the universal head 41.
