Description
Technical field
The invention belongs to field of orthopaedics medical instrument, particular for the steel plate used when fracturing at tibial plateau, specifically
It is related to the miniature dissection of tibial plateau posterior cruciate ligament of knee attachment point fracture and fixes steel.
Background technology
Tibial plateau posterior cruciate ligament of knee attachment point is handed over because of the undue drawing of ligamentaum cruciatum or the effect of strong external force after causing
It pitches and avulsion fracture occurs at ligament attachment point, the bone piece formed at this time is much smaller, it usually needs through shin bone rear openings, carry out
Fixation after reset.
Larger using traditional plate size, property of coincideing is inadequate, and the factor of most critical is the bone piece that avulsion fracture is formed
Smaller, existing steel plate cannot realize the reset and fixation to bone piece well, the bone piece movement problem after fixing often occur,
So as to influence the recovery of patient, although the prior art, which exists, applies tibial plateau back outer side bone plate, such as：For posterior cruciate ligament of knee
The tibial plateau back outer side bone plate fractured at stop
201010607699.X；Though all it is to apply the instrument on tibial plateau, outside and tibial plateau after tibial plateau
Position of the posterior cruciate ligament of knee attachment point on tibial plateau is different, it is necessary to what is solved makes technical problem also differ, mentality of designing
Also differ, therefore the prior art cannot be applied to posterior cruciate ligament of knee attachment point fracture aspect, it is impossible to solve to have bone piece
Imitate the purpose of replacement and fixation.
The present invention is complicated for operation to the tibial plateau posterior cruciate ligament of knee attachment point reduction of the fracture for prior art instrument, bone piece
The problems such as fixed insecure, designs a kind of miniature dissection of tibial plateau posterior cruciate ligament of knee attachment point fracture and fixes steel.
The content of the invention
In order to overcome the prior art complicated for operation to the tibial plateau posterior cruciate ligament of knee attachment point reduction of the fracture, after bone piece is fixed
The problems such as easily shifting；The present invention provides a kind of tibial plateau posterior cruciate ligament of knee attachment point that can effectively solve above-mentioned technical barrier
Steel is fixed in miniature dissection of fracturing.
Steel is fixed in a kind of miniature dissection of tibial plateau posterior cruciate ligament of knee attachment point fracture, tough including intersecting after tibial plateau
The steel plate coincideing with attachment position shape, which is characterized in that the steel plate includes upper end and arc anastomosis on rear side of tibial plateau
Fixed part and the fixed handle coincideing with tibia sites of lower end；Fixed handle is set with fixed part horizontal line into 65-75 ° of inclination angle；Gu
Determine portion upper inner face and the 2-4 fixed quarter butt vertical with medial surface is set；Fixed part both sides, which are set, carries out steel plate and ligament
The suture hole of suture sets 1-3 mounting hole on fixed part；2-4 mounting hole is set on fixed handle；And set corresponding
Several fixing glues.Steel plate is coincide to fracture site during said structure use, is first led back fracture site by fixed quarter butt
Reset to suitable position；Fixing glue is fixed at corresponding bone afterwards；Finally steel plate and ligament are sutured using suture, risen
To the purpose of good replacement and fixation bone piece.
Further, the suture hole is arranged on two middle side part of fixed part position on the lower side.This position set can be very good by
Steel plate is effectively sutured with ligament, and then can be very good fixed position.
Further, flank is set respectively in fixed part both sides, and the setting of flank can be preferably realized to tibial plateau
It coincide and fixes.Further, flank rear end is identical with fixed part.
Further, 1-2 mounting hole is set on every side flank, wherein being preferably provided with 1 mounting hole.
Further, the 2-4 lock holes set obliquely are set on fixed part, wherein preferably 3；And setting pair
The lock hole of number is answered to follow closely；By setting lock hole that fracture bone piece is made, by connecting, to further function as good fixation with lower section
And the purpose that anti-bone piece position changes.
Further, the angle of inclination of the lock hole is to tilt down 20- as reference with fixed part vertical level
40°；Wherein preferred angle of inclination is 30 °.Such angle of inclination very good can connect fracture bone piece and shin bone, play
Fixed effect.
Further, the pore diameter range of the lock hole is 1.6-2.6mm；Wherein preferred aperture size is 2.0mm.Such ruler
Very little setting can be very good locking bone piece, and effectively protect bone piece structure.
Further, the profound length of the fixed part is 20-30mm；Wherein it is preferably 25mm；Such size setting can be very
Good carries out replacement and fixation to most of tibial plateau.
Further, the thickness range of the fixed part and fixed handle is 2-4mm；Wherein it is preferably 3mm；Such thickness can be with
Ensure the toughness and portability of structure.
Further, the direction of the mounting hole is vertical fixed part and fixed handle part；Such mode can be very good
It is fixed.
Further, the aperture size of the mounting hole is the hole of 1.7-3mm, wherein it is preferred that aperture size is 2.4mm.It is such
Aperture design can ensure not the influence caused by shin bone and bone piece, and good fixing effect.
Further, 1-3 mounting hole is set on the fixed part, wherein 2 are preferably designed for, the level of each mounting hole
Spacing is 3-10mm；Wherein it is preferably 8mm.Further, the mounting hole on the fixed part does not weigh staggeredly with fixed quarter butt position
It is folded；Such setting can ensure not interfere with each other between each structure.
Further, the mounting hole on the fixed part is arranged on the lower section of lock hole, and mounting hole is staggeredly set with lock hole
It puts.
Further, the fixed quarter butt length is 8-12mm；Wherein preferred length is 10mm；Such fixed quarter butt length can
To realize the reset and fixation to bone piece well.The a diameter of 1.2-1.5mm of fixed quarter butt, wherein preferably 1.5mm.
Further, 2-4 mounting hole is set on the fixed handle；It is another that a sliding eye slided for fixing glue is set；This
Kind angle setting can realize the fine tuning to steel plate integral position.
Further, the fixed handle length range is 40-70mm；Wherein preferred length is 60mm；Such length can be with
Smaller size realizes the fixation to fracture site.Further, fixed handle is set with fixed part horizontal line into 70 ° of inclination angles.
Further, the width of the fixed handle is 6-10mm, and wherein preferable width is 8mm；Such width can ensure
On handle set mounting hole after handle structure stability.
Further, the scope of the fixed part maximum perpendicular width is 8-12mm；Wherein preferable width is 10mm.
