Abstract
The utility model discloses a direction type kneecap pincers that reset, including reseing the pincers bodies, the head of the pincers body that resets is provided with the pincers screw hole that resets, and the thread tightening of hollow guide thimble through hollow guide thimble front end is on the pincers screw hole that resets. It is inside for circular when the head of the pincers bodies of reseing folds, and the head top has sharp point. Position pincers screw hole is provided with two. The beneficial effects of the utility model are that, the head folds the after -fixing kneecap, produces good external force and makes the fracture stable in order to be used for fixed bone piece and steel sheet. The guide bar combines with the head, can make gram formula needle follow the guide bar and pass through the kneecap sclerotin, reaches disposable fixed best effect. The operation demand that resets of both can having satisfied the demand, it is fixed also can directionally to restrain the formula needle, avoids relapseing many times fixed damage to the sclerotin.
Description
Technical field
This utility model belongs to surgical apparatus technical field, relates 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.
Utility model content
The purpose of this utility model is to provide a kind of guidance type patella reduction forceps, solves problems of the prior art, operative reduction demand of both can having satisfied the demand, and also orientation can give a gram formula pin and fix, and avoids the repeated multiple times fixing damage to sclerotin.
The technical scheme that this utility model adopts is, a kind of guidance type patella reduction forceps, comprise reduction forceps caliper, 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 beneficial effects of the utility model are, head closes up rear fixing patella, produce good external force and impel 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.

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, this utility model 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.
