Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
As shown in Figure 1 to Figure 3, a kind of jaw type Multifunctional elastic intramedullary needle fastener driving device, including handle 1 and it is fixed on handle
The tong bodies 2 of 1 front end；Impactor 7 is connected in the middle part of handle 1；1 rear end of handle is connected with bending machine 8.
The clamp slot 3 of a through slot formula is provided in tong bodies 2, clamp block 4 is located in clamp slot 3 close to clamp slot 3
Upper side；The downside of clamp slot 3 and the downside of clamp block 4 are diamond shape toothed surfaces, in use, elastic intramedullary needle is in clamp slot
3 downside and the downside of clamp block 4 add under clamping, steady operation.Fixed on clamp block 4 there are two guide pins 5, symmetrical to divide
Cloth is in the two sides of push bolt 6；The pilot hole cooperated with guide pin 5 is provided in 3 inner wall of clamp slot；Guide pin 5 is slidably matched peace
In pilot hole, guiding role is played to the movement of clamp block 4.Guide pin 5 and push bolt 6 are each perpendicular to clamp slot 3, push away
