Abstract
The utility model discloses a fixing and removing instrument in orthopedics. The technical scheme is as follows: a lifting and pulling screw (3) is connected with a broken nail grasping part (4) by a bolt; when being taken out, the broken nail is clamped in the broken nail grasping part (4) which is lifted and pulled by a line-shaped screw port (6) of a head part (5) of a rotating bolt; the grasping part is tighten by the gradient of a sleeve of the extracting device to realize the stable fixing of the extracting device and the broken nail; and then holding a handle of the extracting device to screw out the screw. The broken nail extracting device has delicate design, small trauma, safety, big torsion and good effect.
Description
Technical field
This utility model broken nail taking equipment belongs to orthopaedics internal fixation removal equipment.
Background technology
Using screw fixings behind the extremity fracture is present clinical the most frequently used internal fixation mode, some screw retention time in vivo is long, thereby in the functional exercise that lacks reasonable guidance or in the work, because stress-shielding effect, the segment screw nail meets with stresses huge, cause fracture easily, especially the application of titanium alloy has increased histocompatibility, screw combines with sclerotin closely, thereby when taking out screw, just nut and breechblock might be twisted into two parts, thereby the case of broken nail in clinical is more common, common removing method is osteotome and trepan at present, not only technology falls behind, and wound is big, when reply spinal column broken nail, because the position is dark, peripheral vessels is neural near, more resemble and dare the greatest danger, dare not end opening, thereby demand a kind of safe broken nail urgently and take out instrument.
The utility model content
Therefore, the purpose of this utility model provides that a kind of design is ingenious, wound is little, safety, torsion are big, effective, its overcoat is designed to ramp structure, lifts screw screw, grasping part, overcoat are connected as a single entity, and is convenient to take out the cartridge type taking equipment of broken nail.
In order to achieve the above object, this utility model is achieved in that taking equipment (Fig. 1) comprises overcoat handle 1, overcoat foot 2, lifts screw 3, broken nail grasping part 4 and overcoat 5.Lift screw 3 and be connected (Fig. 4) by bolt with broken nail grasping part 4, when getting broken nail broken nail is sandwiched in broken nail clamping part 4, word screw socket by swivel bolt head 6 lifts broken nail grasping part 4, the gradient by the taking equipment cover is tied the grasping part tight, fixedly securing of final realization taking equipment and broken nail, grasp the handle of taking equipment then, screw is screwed out.

Fig. 1 is a broken nail taking equipment full view.1 handle; 2 overcoat feet; 3 lift screw; 4 broken nail grasping parts; 5 overcoats.
Fig. 2 is a broken nail taking equipment front view.
Fig. 3 is a broken nail taking equipment side view.
Fig. 4 comprises view under bolt head top view and the screw grasping part for lifting the screw sketch map
The specific embodiment
Shown in Fig. 4,5,6, lifting screw 3 and broken nail grasping part 4 is connected by bolt, when getting broken nail broken nail is sandwiched in broken nail clamping part 4, word screw socket by swivel bolt head 6 lifts broken nail grasping part 4, the gradient by the taking equipment cover is tied the grasping part tight, fixedly securing of final realization taking equipment and broken nail grasps the handle of taking equipment then, and screw is screwed out.
Further describe below in conjunction with clinical and accompanying drawing: the at first conventional screw that exposes, the scar tissue around the cleaning screw.If the nail tail exposes, then select suitable big or small sleeve trepan, broken nail (or screw) and sclerotin are on every side got out certain interval (exposing 1-2cm), then broken nail is inserted in the broken nail grasping part, twist a word screw socket that lifts screw head with a word screwdriver, taking equipment and broken nail are fixedly secured, grasp the handle of taking equipment then, screw is screwed out.
