Description
Technical field
This utility model relates to a kind of medical domain bone surgery set, relates in particular to the easy device for taking out broken nail of a kind of orthopaedics.
Background technology
In bone surgery, nail and steel plate are conventional apparatuses, need nail, steel plate to take out after knochenbruch healing, in the time getting nail, easily nail are broken, and nail is broken rear difficult taking-up.
China Patent Publication No. 203436390U discloses a kind of nail-fetching device---orthopedics broken nail extractor, comprise a T-shaped handle being formed by cross bar and vertical rod, vertical rod lower end is provided with a hinged seat, hinged seat lower end is hinged with two shanks, two shank lower ends are connected with two cone lobes that left and right is symmetrical, the lower end of cone lobe is most advanced and sophisticated, and tip is provided with external screw thread; One nut is nested with in the middle and upper part of two cone lobes, and both are by threaded engagement, and described nut one side is fixed with driving handle, its reasonable in design, and broken nail taking-up efficiency is high, little to the damage of sclerotin.But the structure of orthopedics broken nail extractor is comparatively complicated, and because broken nail and steel plate are to be threaded, only by upwards pulling out, broken nail is taken out and has certain difficulty, therefore need to do further improvement.
Utility model content
The purpose of this utility model is: provides a kind of orthopaedics easy device for taking out broken nail, broken nail can be taken out easily, and get the effective of broken nail, and simple in structure.
This utility model orthopaedics comprises shaft-like handle with easy device for taking out broken nail, also comprise sleeve, sleeve is the round table-like of hollow, sleeve upper end arranges two handles and penetrates hole, handle penetrates hole horizontal through handle and is arranged on sleeve upper end, opening is vertically set in cartridges sides, external screw thread is set on sleeve, sleeve arranged outside tapered cup nut, tapered cup nut is connected with bush whorl, and sleeve lower end arranges female thread, and the screw-in sheet of ring-type is set on the lateral surface of sleeve lower end, screw in sheet and be used for inserting between broken nail and bone, screw in sheet and can be welded on sleeve lower end.
The thickness that screws in sheet is less than the thickness of sleeve, is conducive to screw-in sheet to insert between broken nail and bone.
A handle penetrates in hole female thread is set, and corresponding external screw thread is set on handle, and handle is connected with bush whorl.Only in a handle penetrates hole, female thread is set, can facilitates handle to pass handle and penetrate hole, and realize being fastenedly connected of handle and sleeve.
Operation principle and process: when use, with hand-held handle, screw-in sheet is put into the contact position of broken nail and bone, rotary handle, makes to screw in sheet and inserts between broken nail and bone, then twist tapered cup nut, make sleeve clamping broken nail, due to the existence of sleeve lower end female thread, the frictional force of sleeve and broken nail is larger, then turning handle, back-outs broken nail come.
The beneficial effect that this utility model compared with prior art had is:
Orthopaedics can take out broken nail easily with easy device for taking out broken nail, and structure is simpler than existing device for taking out broken nail, and cost is lower, and broken nail can be back-outed, and takes out the effective of broken nail, alleviates patient's misery.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, hands handle; 2, sleeve; 3, opening; 4, tapered cup nut; 5, screw in sheet.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, orthopaedics comprises shaft-like handle 1 with easy device for taking out broken nail, also comprise sleeve 2, sleeve 2 is the round table-like of hollow, sleeve 2 upper ends arrange two handles and penetrate hole, handle 1 penetrates hole horizontal through handle and is arranged on sleeve 2 upper ends, sleeve vertically arranges opening 3 on 2 sides, on sleeve 2, external screw thread is set, sleeve 2 arranged outside tapered cup nuts 4, tapered cup nut 4 is threaded with sleeve 2, sleeve 2 lower ends arrange female thread, the screw-in sheet 5 of ring-type is set on sleeve 2 lower end lateral surface, screwing in sheet 5 is used for inserting between broken nail and bone, screw in sheet 5 and can be welded on sleeve 2 lower ends.
The thickness that screws in sheet 5 is less than the thickness of sleeve 2, is conducive to screw-in sheet 5 to insert between broken nail and bone.
A handle penetrates in hole female thread is set, and corresponding external screw thread is set on handle 1, and handle 1 is threaded with sleeve 2.Only in a handle penetrates hole, female thread is set, can facilitates handle 1 to penetrate hole through handle, and realize being fastenedly connected of handle 1 and sleeve 2.
When use, with hand-held handle 1, the contact position that screw-in sheet 5 is put into broken nail and bone, rotary handle 1, makes to screw in sheet 5 and inserts between broken nail and bone, then twist tapered cup nut 4, make sleeve 2 clamp broken nail, due to the existence of sleeve 2 lower end female threads, sleeve 2 is larger with the frictional force of broken nail, then turning handle 1, back-outs broken nail come.
In sum, this utility model can take out broken nail in orthopaedics patient bone, has advantages of more simple in structure, easy to operate than existing device for taking out broken nail and easily takes out broken nail.
