Description

A kind of distal tibial rear side lockplate
Technical field
The utility model relates to lockplates on rear side of surgical medical equipment technical field more particularly to a kind of distal tibial.
Background technique
In bone surgery, need that fracture site is implemented to fix using lockplate and screw.The treatment of distal tibial fracture The always problem of orthopaedics therapy.Due to there is it to dissect particularity on rear side of distal tibial, there is operations to be stranded for common lockplate The problems such as difficult, with knochenbruch mismatch, extends so as to cause operating time, patient's knochenbruch restores slow.Due on rear side of distal tibial its The particularity of bone block position and fracture recovery period are longer, when patient takes exercise after surgery, it is easy to lead to the screw on lockplate It loosens, it is unreliable to support so as to cause lockplate, causes secondary injury to patient.In addition, existing lockplate itself there is Many defects, for example cannot be bonded completely with bone face, oppress periosteum, influence fracture end blood supply etc..It is crushed in distal tibial Property fracture when, the bone block of fracture is usually fixed with steel wire or suture cerclage, due to locking plate surface it is smooth, steel wire or Suture loop, which lashes, is easy sliding when tying up, be unfavorable for stablizing for broken bone block and fix.
Utility model content
In order to solve the above-mentioned prior art problems, the utility model provides a kind of distal tibial rear side lockplate, including Integrally formed head and bar portion;The head, which has, expands the arcwall face that bone section matches with distal tibial rear side;The head Portion's width, which is greater than bar portion and smoothly transits with bar portion in circular arc, to be connect;The head is uniformly provided with four universal holes;It is described universal Hole is cross section in criss-cross column structure and its inner wall is equipped with screw thread, the folder between the axis and head surface in universal hole Angle is 20 °;The surface that bone section is in contact is expanded on rear side of the head and distal tibial is equipped with bed course, the bed course and distal tibial The female parts that rear side expands bone section match;The bar portion has a synthetism face, table on rear side of the synthetism face and distal tibial Face matches;The both sides of the synthetism face length direction are the arc being recessed inwardly, and form relief groove with the opposite face in synthetism face; The relief groove is equipped with multiple threading holes through bar portion;The two edges of the bar portion length direction from close to head one end to One end thickness far from head is gradually reduced;The bar portion is equipped with several screw holes and a pressurization hole;The screw hole Inner wall upper end is smooth inner wall, and inner wall lower end is equipped with oblique cone screw thread;The pressurization hole includes arcuation counterbore and conical screw hole, institute It states arcuation counterbore and is equipped with pressurization slope, the conical screw hole angle of thread is 20 °;The bar portion surface adjacent screw hole and pressurization Groove is equipped between hole.
Preferably, the center in the universal hole is in same straight line.
Preferably, the pressurization hole is set between screw hole, and the center in screw hole and pressurization hole is in the axis of bar portion On.
Preferably, the gradient on arcuation counterbore pressurization slope is 40 °.
Preferably, the lockplate head portion and bar portion are equipped with kirschner pin hole, for by matching with kirschner pin hole Lockplate is fixed on rear side of distal tibial by Kirschner wire.
It preferably, is in angular distribution on lockplate there are three the kirschner pin holes.
In the utility model integrally formed head and bar portion with match on rear side of distal tibial, be able to achieve lockplate with Fitting closely for distal tibial rear side knochenbruch face, is conducive to the quick healing of knochenbruch.The universal hole cross section on head is in cross, Have the function of a variety of direction-lockings.Universal hole is obliquely installed with head surface in 20 ° of angles, after bone screw is to distal tibial Side has certain pulling force, knochenbruch can be helped to reset, and promotes union.Bar portion synthetism face two sides are arc, and bar portion is thick Degree is gradually smaller, realizes lockplate to the Limited contact in knochenbruch face, reduces lockplate to the compressing of periosteum and to soft tissue Stimulation, reduction damaged caused by nerve, be conducive to blood circulation, to be conducive to the recovery of patient's knochenbruch.Bar portion setting Pressurization hole.Pressurization hole is matched with screw hole, be can be avoided knochenbruch face and is misplaced, further strengthens lockplate to knochenbruch Fixed function.Universal hole, screw hole, pressurization hole make lockplate connect with knochenbruch more consolidate, and screw be not easily accessed it is naked Articular cavity.Threading hole can pass through steel wire or suture, and the broken bone block cerclage of fracture is bundled.The bed course on head can make to lock Fixed board is more attached with the bone section of expanding on rear side of distal tibial, increases the stability of lockplate.The groove of bar portion surface setting can With the stress dispersion for being subject to lockplate in fixation procedure, stress is avoided to concentrate, reduces the probability that lockplate fractures.
The utility model not only can guarantee the reliable close fixation on rear side of distal tibial at knochenbruch, and realize lock again Limited contact on rear side of fixed board and distal tibial, the influence to blood vessel, nerve and tendon are small.The utility model is designed reasonably, energy Promote the more preferable healing faster of fracture, shortens treatment time, reduce complication, reduce plasticity probability, mitigate patient suffering, make to suffer from Person's early recovery.
