This utility model solves its technical problem and be the technical scheme is that a kind of fracture with compressive fixation clamps, the upper plier handle connected including intersection hinge and lower plier handle, the front end of upper plier handle and lower plier handle is pincers rostral, having fixing upper plier handle and the lock uint of lower plier handle position between upper plier handle and lower plier handle, described pincers rostral is cylinder clamp rostral.
As preferably, described lock uint includes that screw thread locking bar, traveling nut and locking bar integrated with lower plier handle fix seat, described upper plier handle is fixed position corresponding to seat and is provided with a kidney ellipsoid through hole with locking bar, it is hinged that one end of described screw thread locking bar and locking bar fix seat, and the other end is threadeded with traveling nut after kidney ellipsoid through hole.
As preferably, described traveling nut has a boss near the side of upper plier handle, and the diameter of described boss is equal with the width of kidney ellipsoid through hole.
As preferably, described screw thread locking bar is fixed with, through one end of kidney ellipsoid through hole, the tail cap preventing traveling nut from coming off.
As preferably, said two pincers rostral is 0-10 ° away from the angle of upper plier handle and the extended line in lower plier handle direction.
The beneficial effects of the utility model are: a kind of fracture with compressive fixation clamps that this utility model provides, first pass through the size drilling tool identical with the pincers rostral of fixation clamps to punch in fracture both sides, then two pincers rostrals are inserted in holes respectively, make fracture pressurize further by rotary moveable nut, stablize, and when punching, it is not necessary to stripping further to surrounding soft tissue;Traveling nut has a boss near the side of upper plier handle, and the diameter of boss is equal with the width of kidney ellipsoid through hole, after upper plier handle and lower plier handle being fixed, can effectively prevent rocking of screw thread locking bar.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of a kind of fracture with compressive fixation clamps of the present utility model.
In figure: 1. upper plier handle, 2. lower plier handle, 3. pincers rostral, 4. screw thread locking bar, 5. traveling nut, 6. locking bar fixes seat, 7. kidney ellipsoid through hole, 8. boss, 9. tail cap.
Detailed description of the invention
