Description
Technical field
The utility model relates to medical apparatus more particularly to a kind of orthopaedics steel plate system for external fixation, are used as Orthopedic Clinical
The external fixer for the treatment of.
Background technique
Traditional exterior fixing rack fixing intensity is inadequate, and Bone traction nail is easy to loosen, and traditional Bone traction follows closely thicker, screw way
Infection rate it is higher, and traditional support arm needs trans-articular to fix, and fixed effect is not good enough, is unfavorable for union, and trans-articular
Fixation can bring the complication of anchylosis；Meanwhile traditional exterior fixing rack volume is larger, and patient is caused to wear the clothes and walk not
Just.Clinically there is part doctor by interior fixedly locked steel plate external application at present, but this does not meet the use indication of locking steel plate, and
Function without fracture end pressurization.
Utility model content
The utility model is to provide a kind of orthopaedics steel plate system for external fixation to solve above-mentioned deficiency.
The above-mentioned purpose of the utility model is realized by technical solution below: a kind of outer fixation steel plate system of orthopaedics
System, it is characterised in that: including outer fixation steel plate, lock screw, plain screw and screw sleeve, the outer fixation steel plate is equipped with
Threaded locked holes and non-threaded through-hole, ailhead one end of the lock screw are locked in the screw fastening of outer fixation steel plate by screw thread
Determine on hole, the other end is fixed on skeleton；The plain screw passes through the nothing of outer fixation steel plate from the outside of outer fixation steel plate
Tapped through hole, the plain screw are fixed on skeleton.
Further, it is cased with forcing screw sleeve on the plain screw, plain screw is made to form pulling force forcing screw.
Further, the non-threaded through-hole is circular hole or slotted eye.
Further, the pulling force forcing screw and the perpendicular shape of outer fixation steel plate or skewed connection.
Further, the forcing screw sleeve is locked on outer fixation steel plate or is not locked on outer fixation steel plate.
Further, the lock screw, plain screw include full thread nail and half-thread nail.
Further, the forcing screw sleeve is not provided with threaded portion, or equipped with the screw thread connecting with outer fixation steel plate
Portion.
Further, the forcing screw sleeve includes linear type or two kinds of bias type.
The utility model compared with prior art the advantages of be:
1. the utilization of the utility model, make bone surgery as much as possible and become Minimally Invasive Surgery that (hand can be completed in small notch
Art), soft tissue destruction is reduced, the removing of periosteum is especially reduced, the destruction of sclerotin blood supply is reduced, is conducive to union, is reduced
Because of the generation that tendon muscle caused by operation is adhered, reduces and cause nerve because performing the operation big notch, blood vessel, the generation of tendon injury
Rate reduces soft tissue necrosis, infection of incisional wound, fracture delayed union, the risk of bone nonunion.
2. the utilization of the utility model keeps surgical procedure easy, technical requirements threshold is low, shortens operating time, reduces hand
Art risk improves the working efficiency of operative doctor.
3. once operation (taking steel plate without second operation) can complete the dismounting of steel plate in minor operation room, mitigate and suffer from
The financial burden of person and second operation bring pain, save medical resources, while being not in screw stripped thread, it is implanted into steel plate
The case where can not taking.
4. outer fixation steel plate application lock screw, head of screw is snapped and steel compared with traditional single armed integral type support arm
Plate is fixed, and lock screw and steel plate are combined into a secured entirety, and bone block is stablized fixation, enough can be provided on sclerotin
Holding force is superior to traditional exterior fixing rack in rigidity, firmness, stability, curvature, while solving exterior fixing rack
The shortcomings that fixing intensity is inadequate, and Bone traction nail loosens, screw are thinner than traditional Bone traction nail, reduce the infection rate of screw way.From life
It is seen in material resources and complies fully with External fixation use, for outer fixation steel plate closer to skin, the arm of force is smaller, the stress born
It is smaller, therefore security and stability is stronger.Traditional support arm needs trans-articular to fix, and can bring the complication of anchylosis in this way,
Outer fixation steel plate it is postoperative can early functional exercise, reduce the generation of anchylosis, meet modern medicine quick recovery theory.
5. clinically having part doctor by interior fixedly locked steel plate external application at present, but this does not meet compared with locking steel plate
The use indication of locking steel plate, and do not have the function of fracture end pressurization yet.This outer fixation steel plate can provide good fracture
The effect of end pressurization, it may advantageously facilitate union.
6. life convenient is compared to traditional exterior fixing rack, outer fixation steel plate is small and exquisite, is tightly attached to skin, is conducive to
Patient wears the clothes and walks, and normal social activity is unaffected, and outer fixation steel plate equipment is simple, convenient for self nursing of patient.
7. applied widely, open fracture, closed fracture can be applied.Osteomyelitis, soft tissue infection's disunion, bone
It defect and can also be applied with the disease of serious soft tissue injury.
8. Follow-up After, the patient after the treatment of outer fixation steel plate, postoperative imageological examination, which is more clear, to be defined, (compare
The case where will appear artifact when the x-rays CT examination such as traditional support arm or steel plate) union feelings can be more clearly observed
Condition.
