Description
Technical field
The present invention relates to Medical fracture surgical technic fields, specifically, being a kind of tibial insertion of posterior cruciate ligament fracture
Make internal fixation steel plate by oneself.
Background technique
The method of knee-joint posterior cruciate ligament tibia stop avulsion fracture operative treatment mainly has solid in open reduction at present
Replacement and fixation under fixed and arthroscope.Arthroscopic diagnosis is relatively minimally invasive, but PCL shin bone dead-centre position is deep, after tibial plateau
Side, arthroscopic diagnosis the disadvantages of there are complicated for operation, time-consuming, the reduction of the fracture is inaccurate.Usual open reduction and Kirschner wire fixation material is answered
With fixed posterior cruciate ligament of knee attachment point avulsion bones such as steel wire, high-intensitive suture, hollow screw, bioabsorbable interference screw and independent holdfasts
Folding, since bone block is smaller, crush bone block often cannot firm fixation, the postoperative outer fixation for being both needed to the long period, to delay knee
The time of joint exercise.Traditional T-steel plate radian is inadequate, and bending moulding is difficult in art, cannot accurately fix sclerite,
Operating time is increased, interior fixed curative effect is influenced.

Pitch the novel fixing device of ligament shin bone stop avulsion fracture.Disclose a kind of knee-joint posterior cruciate ligament tibia stop avulsion bone
The novel fixing device of folding belongs to orthopedic medical device technical field, it is intended to solve to intersect after existing knee joint tough
Band shin bone stop avulsion fracture is postoperative to be fixed gypsum for a long time, and there are problems that fractureing.The fixation bone fracture plate main body that it is used
It is the fixation bone fracture plate main body of I-shaped shape, S-shaped bent plate face, several cooperation loads is formed respectively in fixation bone fracture plate main body and are fixed
The countersunk screw holes of screw, and transversely arranged at the top of the stub end of fixation bone fracture plate main body I-shaped shape plate face it is formed with 2-4 load
The through-hole of ligament.
Chinese patent literature: CN201810065065.2, applying date 2018.1.23, patent name are as follows: handed over after tibial plateau
Pitch the fixed steel of the miniature dissection of ligament attachment point fracture.Disclose a kind of miniature dissection of tibial plateau posterior cruciate ligament of knee attachment point fracture
Fixed steel comprising the identical steel plate of tibial plateau posterior cruciate ligament of knee attachment position shape, which is characterized in that the steel plate includes
The fixed part of arc anastomosis and the fixed handle of lower end coincideing with tibia sites on rear side of upper end and tibial plateau；Fixed handle and solid
Determine portion's horizontal line to be arranged at 50-70 ° of inclination angle；The 2-4 fixed quarter butt vertical with medial surface is arranged in fixed part upper inner face；Gu
Determine the suture hole that the setting of portion two sides sutures steel plate and ligament, several fixation holes to be respectively arranged on fixed part and fixed handle；
And the fixing glue of corresponding number is set.The 2-4 lock holes being arranged obliquely are separately set on fixed part, and corresponding number is set
Purpose lock hole nail；Make fracture bone block and lower section by connecting by the way that lock hole is arranged.
One of above patent document CN201620025670.3 knee-joint posterior cruciate ligament tibia stop avulsion fracture
Novel fixing device, it is simple and practical in structure, it is postoperative to be fixed without gypsum, it is safe and convenient to use, suitable for being handed over after knee joint
Pitch the strong fixation of ligament shin bone stop avulsion fracture and the reconstruction of ligament；And in patent document CN201810065065.2
Tibial plateau posterior cruciate ligament of knee attachment point fracture the fixed steel of miniature dissection, steel plate coincide to fracture site by when use, passes through
Fixed quarter butt, the setting of three structure of suture hole and lock hole can effectively realize reset to bone block and the anti-skidding effect of multiple fixation
Fruit.But meet anatomic form at tibial plateau posterior cruciate ligament of knee stop about one kind, facilitate reseting fracture end in art, reduces hand
Art time, strong fixed fracture end reduce a kind of avulsion fracture of posterior cruciate ligament insertion self-control of knee joint early functional exercise time
Internal fixation steel plate is at present then without relevant report.
Summary of the invention
The purpose of the present invention is aiming at the shortcomings in the prior art, provide one kind to meet tibial plateau posterior cruciate ligament of knee stop
Locate anatomic form, facilitate reseting fracture end in art, reduce operating time, strong fixed fracture end reduces knee joint early function
A kind of tibial insertion of posterior cruciate ligament fracture self-control internal fixation steel plate of exercise time.
To achieve the above object, the technical solution adopted by the present invention is that:
A kind of tibial insertion of posterior cruciate ligament fracture self-control internal fixation steel plate, which is characterized in that the posterior cruciate ligament of knee
Shin bone stop fracture self-control internal fixation steel plate includes steel plate main body；The steel plate main body is integrally flat by distal end, middle-end and proximal end
It slips over and crosses to be formed, whole in bending T-shape structure, proximal end is in a vertical shape；Two are transversely provided in the steel plate body distal end
First screw hole and second screw hole, and be between two the first screw holes and the second screw hole
Symmetrical structure；The steel plate body distal end is longitudinally respectively equipped with the second screw hole and third screw hole；Described
The second screw hole in the second screw hole and distal end on distal end is same size；The steel plate proximal is horizontal
Three screw holes being equipped with upwards are respectively directed to sclerite, and two screw holes that proximal end longitudinal direction is equipped with respectively refer to
Above to tibial tubercle.
As a kind of perferred technical scheme, the steel plate body distal end lateral length is 24mm, middle-end and proximal end
Width is 11mm；The total length of the steel plate ontology 1 is 60mm.

As a kind of perferred technical scheme, tibial insertion of posterior cruciate ligament fracture self-control internal fixation steel plate also wraps
Include reinforcement nail hole.
As a kind of perferred technical scheme, the reinforcement nail hole is set to steel plate ontology middle-end medium position.
The invention has the advantages that:
1, integrally it is in the design for being bent T-shape structure using steel plate main body, intersects plasticity bending at stop after opposite shin bone,
So that steel plate radian is met anatomical features, facilitate reseting fracture end in art, reduces operating time, and steel plate ontology bending part is whole
Smooth type can effectively increase armor plate strength.
2, three screw holes being transversely provided in steel plate body distal end can utilize screw by steel plate ontology and fracture
Bone block is fixed, and two screw holes for being set to proximal end longitudinal direction then pass through screw and consolidate steel plate ontology with above tibial tubercle
It is fixed, the tissue of stimulation front side of shin bone is avoided while to guarantee effectively fixed.
3, by the way that proximally and distally the design of totally five screw holes may make the fixation of fracture end more firm, favorably
In the reduction knee joint early functional exercise time.
It 4, can be in steel plate ontology using proximally and distally using reinforcement nail hole is equipped at steel plate ontology middle-end medium position
On screw hole it is fixed after, then be subject to strengthening nail and fix, so that the fixation of steel plate ontology is more firm.
