The utility model discloses a kind of composite tools for
extracorporeal circulation, including connecting rod, respectively be set in the percussion hammer connecting end and scissors connecting end of connecting rod opposite two ends, percussion hammer connecting end is connected with percussion hammer, and scissors connecting end is provided with receiving cavity, and receiving cavity is provided with scissors, and the width of receiving cavity is greater than the
diameter of connecting rod. By setting receiving cavity in the east connecting end of connecting rod, scissors can be accommodated in receiving cavity;When percussion hammer is needed, it can be used directly, and when scissors are needed, it can be taken out and used, and after the use of scissors is completed, it is collected in receiving cavity again, which avoids the loss of small items such as scissors after use, makes scissors easy to carry, and avoids the carrier being pricked by scissors;The percussion hammer is connected to the receiving cavity containing scissors through the connecting rod, and the width of the receiving cavity is greater than the
diameter size of the connecting rod, which effectively increases the overall volume of the percussion hammer, and avoids the phenomenon that the percussion hammer and the scissors are too small and easy to lose.
