Abstract
The present invention discloses guiding type patella reduction forceps. The guiding type patella reduction forceps comprise a reduction forceps body; head portions of the reduction forceps body are provided with reduction forceps threaded holes; and a hollow guide bushing is fixed to each reduction forceps threaded hole via a thread at the front end of the hollow guide bushing. When the head portions of the reduction forceps body are folded, the inside is circular, and the top of each head portion is provided with a sharp tip. The number of the reduction forceps threaded holes is two. The guiding type patella reduction forceps have the beneficial effects that the head portions are folded to fix a patella, and good external force is generated to stabilize fracture so as to fix a bone block and a steel plate. Guide bars are combined with the head portion, so that Kirschner wires can pass through patella bone along the guide bars, and the optimum effect of one-time fixation is achieved. Operation reduction requirements can be satisfied, the Kirschner wires can be fixed directionally, so that the bone can be prevented from being damaged due to repeated fixation.
Description
Technical field
The invention belongs to surgical apparatus technical field, relate to a kind of guidance type patella reduction forceps.
Background technology
Patella fracture is one of clinical common classification of fracture, but the reduction forceps used in reduction of the fracture process often can affect Kirschner wire inserting needle position or occur the problems such as gram formula pin position is bad, especially for the less doctor of the lower experience of the age and service seniority, repeated multiple times gram formula pin fixation procedure is there will be in art, therefore the iatrogenic injury of sclerotin is not only caused, more extend operating time, bring certain complication to clinical treatment.
Summary of the invention
The object of this invention is to provide a kind of guidance type patella reduction forceps, solve problems of the prior art, operative reduction demand of both can having satisfied the demand, also orientation can give a gram formula pin and fix, avoid the repeated multiple times fixing damage to sclerotin.
The technical solution adopted in the present invention is, a kind of guidance type patella reduction forceps, comprises reduction forceps caliper, and the head of reduction forceps caliper is provided with reduction forceps screwed hole, and hollow guiding sleeve pipe is screwed on reduction forceps screwed hole by hollow guiding sleeve pipe front end.
Further, inner for circular when the head of reduction forceps caliper closes up, and apical head has sharp keen point.
Further, reduction forceps screwed hole is provided with two.
The invention has the beneficial effects as follows, head closes up rear fixing patella, produces good external force and impels fracture stabilization with in order to fixing bone block and steel plate.Guide post is combined with head, can make gram formula pin along guide post by patella sclerotin, reach the optimum efficiency one-time fixed.Both can to have satisfied the demand operative reduction demand, and also orientation can to have given a gram formula pin and fix, avoid the repeated multiple times fixing damage to sclerotin.
Accompanying drawing explanation
Fig. 1 is the structural representation of guidance type patella reduction forceps.
Fig. 2 is guide post part-structure schematic diagram.
Fig. 3 is the structural representation that reduction forceps connects hollow guiding sleeve pipe place.
In figure, 1. reduction forceps screwed hole, 2. reduction forceps caliper, 3. hollow guiding sleeve pipe, 4. screw thread.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
A kind of guidance type patella reduction forceps, for the guiding that the reset in Patella fracture art and gram formula pin are fixed.
Structure as Figure 1-3, comprises reduction forceps caliper 2, and when the head of reduction forceps caliper 2 separates, both sides are respectively semicircle, for circular when closing up, and has sharper keen point, complete packet can contain patella.The head of reduction forceps caliper 2 is provided with reduction forceps screwed hole 1, and hollow guiding sleeve pipe 3 is fixed on reduction forceps screwed hole 1 by the screw thread 4 of hollow guiding sleeve pipe 3 front end.
Hollow guiding sleeve pipe 3 is dismountable sleeve pipe, and by detachable in reduction forceps screwed hole 1 art, centre is hollow, all can use on reduction forceps caliper 2 both sides.
The head of guidance type patella reduction forceps is semicircle, and both sides close up for circle, similar to patella profile.Head closes up rear fixing patella, produces good external force and impels fracture stabilization with in order to fixing bone block and steel plate.Hollow guiding sleeve pipe 3 is combined with head, can make gram formula pin along hollow guiding sleeve pipe 3 by patella sclerotin, reach the optimum efficiency one-time fixed.Handle portion is patient's operating area.
Claims (3)
