Abstract
The utility model discloses a beating type wedge-shaped nail puller which comprises a fixed U-shaped wedge head (1), a sliding rod (2) and a handle (3), wherein the fixed U-shaped wedge head (1) is fixed at the lower end of the sliding rod (2). The beating type wedge-shaped nail puller is characterized in that a movable U-shaped wedge head (4) is arranged opposite to one side of the fixed U-shaped wedge head (1); the sliding rod (2) is connected with a left beating hammer (7) and a right beating hammer (8) by a left fixed rod (5) and a right fixed rod (6); and the head parts of the left beating hammer (7) and the right beating hammer (8) respectively correspond to the rear part of the fixed U-shaped wedge head (1) and the rear part of the movable U-shaped wedge head (4). The beating type wedge-shaped nail puller has the advantages that when a nail pulling slot on a nail cap is ground to be flat, and a screw driver can not be used for pulling out a bone nail, the beating type wedge-shaped nail puller can pull out the bone nail smoothly, thus having convenient use; by adopting a relative-beating mode, the bone nail is not stressed slantingly, thus avoiding damage on bone mass in pulling; and simultaneously, the beating type wedge-shaped nail puller also reduces pressure on the bone mass in nail pulling.
Description
Technical field
This utility model relates to a kind of improvement of nail-fetching device for orthopaedics, and specifically a kind of impact type wedge shape nail trips out device.
Background technology
Adopt steel plate and nail that fracture is carried out the important means that internal fixation is the treatment fracture, steel plate and nail in time must be taken out again after the union of fracture.At present the nail that uses comprises that the nail body and the head of a nail constitute, and is provided with nail pulling groove on the head of a nail, during nail nipping, blocks nail pulling groove on the head of a nail with screwdriver, and nail is screwed out.Because time of existing in bone of nail is longer, nail can produce certain corrosiveness, causes nail to be difficult to trip out, and when with screwdriver rotation nail, the nail pulling groove on the head of a nail polishes easily, makes that nail is more difficult to trip out.
Summary of the invention
After the purpose of this utility model is to provide a kind of nail pulling groove on the head of a nail to be polished, can not rise with screwdriver under the situation of nail, the impact type wedge shape nail that nail can be tripped out trips out device.
For reaching above purpose, the technical scheme that this utility model adopted is: this impact type wedge shape nail trips out device, by fixing " U " shape wedge head, slide bar, handle constitutes, fixing " U " shape wedge head is fixed on the lower end of slide bar, handle is fixed on the upper end of slide bar, it is characterized in that being provided with activity " U " shape wedge head in a side relative with fixing " U " shape wedge head, on slide bar, be provided with a left side, right fixed bar, on a left side, the end of right fixed bar connects by rotating shaft respectively goes up a left side, hammer is played in right click, a left side, right click is beaten between the upper end of hammer and is provided with trapezoidal sliding sleeve, a left side, the head that hammer is played in right click corresponds respectively to the back of fixing " U " shape wedge head and the back of activity " U " shape wedge head, on a left side, right click is beaten between the shank of hammer and also is provided with the tractive spring, be provided with in the upper end of trapezoidal sliding sleeve and carry handle, be provided with the promotion spring between handle and the handle carrying, a left side, hammer is played in right click can impact the back of fixing " U " shape wedge head and the back of activity " U " shape wedge head simultaneously, fixing " U " shape wedge head and activity " U " shape wedge head move toward one another.
This utility model is also implemented by following measure: " U " of described fixing " U " shape wedge head and movable " U " shape wedge head mouthful width is consistent with the diameter of nail nail body; The upper end axis hole of movable " U " shape wedge head is a bar hole, is provided with spring at the downside of axle.
The beneficial effects of the utility model are: in orthopaedics is clinical, after the nail pulling groove on the head of a nail is polished, can not rise with screwdriver under the situation of nail, trip out device, can extract nail smoothly by this impact type wedge shape nail, and easy to use; Owing to adopted the mode that impacts relatively, it is stressed to make nail not produce deflection, has guaranteed that nail vertically extracts, and has avoided in withdrawal process the damage to sclerotin; Because movable " U " shape wedge head is that its active force does not act on the steel plate, so alleviated the pressure to sclerotin in the nail pulling process at the upside of fixing " U " shape wedge head in the process of wedging.
