Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of detailed description of the invention of the present utility model is explained.
This utility model relates to a kind of extracorporeal circulation pipeline double wall pincers, comprise caliper, connector, binding clip, card, it is characterized in that caliper comprises left caliper 1 and right caliper body 2, left caliper is connected by hinge arrangement 3 with the front end of right caliper body, connector comprises left connector 4 and right connector 5, left connector 4 is fixed on the front end of left caliper 1 and forms integrative-structure, that right connector 5 is fixed on right caliper body 2 and form integrative-structure, the side that left connector 4 is relative with right connector 5 has T-slot 6, binding clip comprises left binding clip 7 connector and right binding clip 8, left binding clip 7 and right binding clip 8 are respectively arranged with the bulge-structure 9 matched with T-slot 6, being removably connected by match T-slot 6 and bulge-structure of left connector 4 and right connector 5 and left binding clip 7 and right binding clip 8, when left binding clip 7 or right binding clip 8 damage or pollute, binding clip is replaceable, miscellaneous part can continue to use, reduce the wasting of resources, binding clip can be replaced flexibly, adapt to the needs of different puncture site, the rear inside of left caliper 7 and right caliper body 8 is provided with the left card 10 and right card 11 that cooperatively interact, safety buckle 12 is arranged on the below of the hinge arrangement of caliper, the corresponding surface of left binding clip 7 and right binding clip 8 is all established tooth engaged 13 and pipeline draw-in groove 14, tooth engaged 13 is arranged on pipeline draw-in groove 14 front end, tooth engaged 13 manages for the blocking-up of extracorporeal circulation pipeline, the contact surface of tooth engaged 13 is round and smooth, reduce and pipeline arrangement be can be used for the damage pipeline draw-in groove 14 of extracorporeal circulation pipeline, .
