Abstract
The utility model discloses a kind of patella steel plate being used for the treatment of Patella fracture.This patella steel plate, comprises the patella steel plate body with crooked radian, and described patella steel plate body comprises top arc and bottom arc, and arc two ends, top and arc two ends, bottom are connected with middle part arc, and top arc bends to patella; Described patella steel plate body sidewall all offers the locking nail hole of multiple installation pinning, and patella steel plate body offers multiple arcuate groove near patella side.This utility model structure is simple, reasonable in design, the patella steel plate body ratio of arc is easier to fit with patella, raising encircles polymerization effect to pulverizing patella, patella steel plate body offers multiple arcuate groove near patella side, can reduce the contact area between patella steel plate and patella, makes blood flow unimpeded, reduce damage, thus strengthen kneecap symphysis.
Description
Technical field
This utility model relates to orthopedic medical device technical field, especially a kind of patella steel plate being used for the treatment of Patella fracture.
Background technology
Patella is sesamoid bone maximum in whole body skeleton, can play protection knee joint, strengthen the coaster effect of quadriceps strength and last 10 ~ 15 ° of straighten knee joint.Patella fracture is common intra-articular fracture, and incidence rate accounts for 1.65% of whole body fracture and injury.
The method of clinical treatment Patella fracture can be divided into the conservative and large class of operative treatment two.To the Patella fracture without displacement, usually fix with Gypsum Fibrosum or brace.Operation is the major way for the treatment of Patella fracture, adopts patella ring in the operation of current treatment Patella fracture, traditional patella ring be circular and Vertical dimension without radian, cannot fit with patella, polymerization effect difference is encircled to the patella of pulverizing.Meanwhile, during patient activity's knee, because patella ring cannot be fitted with patella, cause local twinge, even poke the complication such as skin, cause suffering to patient, unfavorable functional rehabilitation.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of structure simple, laminating patella and broken patella is continued to the patella steel plate of dynamic pressurized.
This utility model solves the technical scheme that its technical problem adopts: a kind of patella steel plate, comprise the patella steel plate body with crooked radian, described patella steel plate body comprises top arc and bottom arc, arc two ends, top and arc two ends, bottom are connected with middle part arc, and top arc bends to patella; Described patella steel plate body sidewall all offers the locking nail hole of multiple installation pinning.Patella steel plate body is rustless steel or titanium alloy material.
Further, in order to increase the intensity of patella steel plate, described top arc, middle part arc and bottom arc are formed in one structure.
Further, described top arc radius is greater than bottom arc radius.
Further, patella steel plate body offers multiple arcuate groove near patella side.
The beneficial effects of the utility model are: this utility model structure is simple, reasonable in design, easy to operate, the patella steel plate body ratio of arc is easier to fit with patella, continues dynamic pressurized to broken patella, raising encircles polymerization effect to pulverizing patella, patella steel plate body offers multiple arcuate groove near patella side, can reduce the contact area between patella steel plate and patella, makes blood flow unimpeded, reduce damage, thus strengthen kneecap symphysis.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left side view of Fig. 1.
Wherein: 1. top arc, arc 2., arc 3., 4. locking nail hole, 5. pinning, 6. arcuate groove.
Detailed description of the invention
By reference to the accompanying drawings this utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with this utility model.
Patella steel plate as depicted in figs. 1 and 2, comprise the patella steel plate body with crooked radian, described patella steel plate body comprises top arc 1 and bottom arc 3, and top arc 1 two ends and bottom arc 3 two ends are connected with middle part arc 2, and top arc 1 bends to patella; Patella steel plate body sidewall all offers the locking nail hole 4 that nine are installed pinning 5, and patella steel plate body offers six arcuate grooves 6 near patella side.
Top arc 1, middle part arc 2 and bottom arc 3 are formed in one structure; Top arc 1 radius is less than bottom arc 3 radius.
Before using, due to patella steel plate and pinning sterilized, must clean and stringent sterilization with water for injection; During use, doctor should develop programs according to the concrete condition of patient, and one end of pinning 5 is divided into two, can separate, and then pinning 5 is not easily skidded off in locking nail hole 4, be fixed on patella by patella steel plate during operation by pinning 5 after inserting locking nail hole 4.
This patella steel plate is easy to operate, the patella steel plate body ratio of top arc 1, middle part arc 2 and bottom arc 3 composition is easier to fit with patella, pinning 5 is loaded in locking nail hole 4, this design can continue dynamic pressurized to broken patella, improve to pulverize patella encircle polymerization effect, patella steel plate body offers six arcuate grooves 6 near patella side, the contact area between patella steel plate and patella can be reduced, make blood flow unimpeded, reduce damage, thus strengthen kneecap symphysis.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content in description, must determine its technical scope according to right.
