Detailed Description

In order to more clearly describe the technical content of the present invention, the following further description is given with reference to specific embodiments.

The utility model discloses a this bone-holding forceps device of realization location direction and drilling function wherein comprises stand pipe 1, ware body frame and lock rack 4, stand pipe 1 fix the head at the ware body frame, the ware body frame including left pincers handle 2 and right pincers handle 3, left pincers handle 2 and right pincers handle 3 pass through the screw transposition, left pincers handle 2 and right pincers handle 3 support and rotate around the screw, the end of stand pipe 1 fix the head at right pincers handle 2, the one end of lock rack 4 assemble to the afterbody of left pincers handle 2, the other end of lock rack 4 can be fixed with 3 joints of right pincers handle.

As the utility model discloses a preferred embodiment, the end of stand pipe 1 have the screw thread, the head of right pincers handle 2 has the mounting hole, the screw thread of stand pipe 1 changes over to the mounting hole of right pincers handle 2.

As the preferred embodiment of the utility model, the tail end of the right forceps handle is provided with a tooth-shaped structure which can be clamped on the lock rack.

As the preferred embodiment of the utility model, the end and the front end of the locking rack 4 are both provided with a plurality of dentations, and the dentations of the right forceps handle 2 can be connected with the dentations of the arbitrary locking rack 4.

As the preferred embodiment of the utility model, the one end of lock rack pass through the screw and the end connection of left pincers handle, the other end support of lock rack rotate around the screw.

The utility model discloses an among the embodiment, only need have a holding forceps clamping part after improving prior art, can snatch the fracture position, temporarily fix and play the guide effect and play the bone holding effect to the kirschner wire drilling when the needle is worn to fix including the outside including. The clamping part of the bone holding forceps is used for positioning, guiding and drilling the drill bit through the guide tube 1, so that the drill hole cannot be deviated.
