Abstract
The utility model relates to a gather kneecap ware, including gathering the kneecap claw, gather the waist that the kneecap claw includes the side bend, the both ends of waist connect respectively at least two with the stationary dog of waist syntropy side bend, the stationary dog afterbody is the point hook, the waist both ends have at least a stationary dog to open respectively and have the through -hole. The utility model discloses can realize the three -dimensional fixed of kneecap fracture department, prevent that the gather kneecap ware spring is not hard up, obtain the sufficient power of controlling, ensure not shift at the knitting in -process, reduce the internal fixation fracture, can satisfy the activity of early limbs again, avoid the bone anchylosis to take place, do benefit to the union.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of patella fracture fixator.
Background technology
Comminuted fracture of patella is a kind of common classification of fracture clinically, many caused by direct violence, account for 1% of whole skeletal injury, Patella fracture methods of internal fixation is of a great variety clinically at present, comprise steel wire circular ligate, tension band wiring, patella claw etc., wherein the fixed effect of patella claw is obviously better than ring like steel wire and fixes, and there is pressurization, add pressure energy and obviously promote the strong of internal fixtion, by anatomical reduction and the pressurization of fracture, the contact friction force between fracture can be increased, protection Reestablish blood supply, new bone is made to cross over fracture gap, promote union of fracture, postoperative can early functional exercise, reduce the complication such as knee stiffness.But the model of patella fracture fixator is fixed in the market, and kind is few, each patella individual variation can not be met far away, in art, difficulty is selected to patella fracture fixator model, large model patella fracture fixator is fixing unstable, and functional jaw very easily thrusts articular cavity, causes operative failure maybe can not play tension band effect; Ting model patella fracture fixator hold weakens, and easily causes sclerite to overturn forward.Because patella fracture fixator contacts with patella not good, toward there is displacement fracture or patella fracture fixator fracture in postoperative fracture recovery process, even there is poly-kneecap slip phenomenon, spirit and economic burden being caused to patient, also easily causes medical tangle.
Utility model content
This utility model aims to provide a kind of patella fracture fixator, Patella fracture place is obtained three-dimensional fixing, guarantees not to be shifted in knitting process, be beneficial to union of fracture.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of patella fracture fixator, comprises poly-kneecap pawl; Described poly-kneecap pawl comprises the waist of lateral bending, the two ends of described waist connect respectively at least two with the fixed claw of waist lateral bending in the same way; Described fixed claw afterbody is sharp hook; Waist two ends have at least a fixed claw to have through hole respectively.
Further, also comprise staple, described staple and through hole adaptation.
Preferably, the two ends of described waist are symmetrically arranged with three fixed claws; Fixed claw width placed in the middle is greater than the fixed claw of both sides; Described through hole is located on fixed claw placed in the middle.
Preferably, described staple is hollow nail.
Preferably, described staple is half-thread nail; Staple end abate.
Further, described waist is provided with screwed hole.
Further, described screwed hole is provided with 2 ~ 4.
Further, described waist and fixed claw are integrated manufacture.
Further, described through-hole diameter is 3.5mm; Described staple diameter is 3.5mm.
Further, described screwed hole path is 2.5mm.
Compared with prior art, this utility model has following beneficial effect:
Through hole on the fixed claw of waist two ends, can with the use of staple, the three-dimensional realizing fracture is fixed, prevent from patella fracture fixator from bouncing to loosen, obtain enough holds, guarantee not to be shifted in knitting process, reduce internal fixtion to split, early stage limb activity can be met again, avoid the stiff generation of osteoarthrosis, be beneficial to union of fracture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is left view of the present utility model;
In figure: 1-waist, 2-fixed claw, 3-staple, 4-screwed hole.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, this utility model is further elaborated.
As shown in Figure 1, 2, a kind of patella fracture fixator disclosed in this utility model, comprises poly-kneecap pawl, and poly-kneecap pawl comprises the waist 1 of lateral bending, the two ends of waist 1 connect respectively at least two with the fixed claw 2 of waist 1 lateral bending in the same way, fixed claw 2 afterbody is sharp hook; Waist 1 two ends have at least a fixed claw 2 to have through hole respectively; Patella fracture fixator also comprises the staple 3 with through hole adaptation; Preferably, the two ends of waist 1 are symmetrically arranged with three fixed claws 2; Fixed claw 2 width placed in the middle is greater than the fixed claw 2 of both sides; Through hole is located on fixed claw 2 placed in the middle.Staple 3 adopts hollow nail, can put in the hole of hollow nail by Kirschner wire, be that guide pin squeezes into hollow nail with Kirschner wire; Staple 3 is half-thread nail, and distal threads can be pressurizeed to fracture, coordinates patella fracture fixator stable fracture place more; Staple 3 end abate, reduces the stimulation to knee soft tissue, avoids causing pain; Waist 1 is provided with screwed hole 4, carries out monolayer cortex fix by screwed hole 4 pairs of comminuted fracture blocks, makes sclerite can not at will movement; Screwed hole 4 is provided with 2 ~ 4, better to comminuted fracture block monolayer cortex fixed effect; Waist 1 and fixed claw 2 are integrated manufacture; Through-hole diameter is 3.5mm; Staple 3 diameter is 3.5mm, and screwed hole 4 path is 2.5mm.
After patella fracture fixator firmly grasps patella, be that hollow nail 3 is squeezed into through hole by guide pin with Kirschner wire, the three-dimensional realizing Patella fracture place is fixed, prevent from patella fracture fixator from bouncing to loosen, obtain enough holds, guarantee not to be shifted in knitting process, reduce internal fixtion to split, early stage limb activity can be met again, avoid the stiff generation of osteoarthrosis, be beneficial to union of fracture.
Certainly; this utility model also can have other various embodiments; when not deviating from this utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and distortion according to this utility model, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by this utility model.
