Description
Technical field
This utility model relates to a kind of internal fixation steel plate being suitable for minimal invasive operation long bone fracture, belongs to orthopedic medical device technical field.
Background technology
Long bone fracture is commonly encountered diseases and the frequently-occurring disease of orthopaedics, be mostly caused by being thumped, vehicle accident, sports, climb the mountain, the movable and place such as construction site is region occurred frequently, suffer from osteoporotic old people in addition and to be collided with or fall the generation that also can cause fracturing.There is following problem in the morbidity of current long bone fracture and treatment:
Proximal humeral fracture accounts for the 4%-5% of whole body fracture, and age and sickness rate are proportionate, and women is about male 2 times.15% is wherein had to be complicated, unstable fracture, wherein the most common with simple surgery neck again.When fracture of surgical neck is simultaneously with large and small tuberosity fracture and dislocation of shoulder, namely when Neer typing three, four partial fractures, because classification of fracture is complicated, treatment difficulty is large, general expectant treatment is difficult to obtain promising result, mostly need take operative treatment clinically.The operative approach that traditional incision redution-in-fixed is conventional is through triangular muscle pectoralis major inter-drain approach, and inside-fixture is main mainly with locking steel plate.In art need from disconnected anterior margin of deltoid and extensively the loosening of front of carrying out fracturing, the large-scale soft tissue of row peel off, the blood fortune of fracture surrounding and sclerite will certainly be affected like this, add the ischemic necrosis probability of the rear head of humerus of fracture, cause the probability that bone does not connect or infection occur to increase.And excessive wound makes muscle group swelling, pain, adhesion around shoulder joint, affect the early stage recovery function of shoulder joint and take exercise.
Methods for Distal Femoral Fractures comprises the inside and outside condylar fracture of femur, the supracondylar fracture of the femur within intercondylar fracture of the femur and distance articular surface 15cm.This position mostly is spongy bone, and pulp cavity is wider, and with the development of transportation and industrial or agricultural, causing this position to fracture by high-energy violence has the trend increased, and the state of an illness is complicated, and degree of injury is serious.It is often with the damage of serious soft tissue injury, fracture pulverizing, Cranial defect, knee joint and quadriceps femoris Quadriceps mechanism.Factors causes clinical treatment comparatively difficult.Anatomical reduction is required to its treatment, strong fixing, early functional exercise.Traditional internal fixation operation of cutting and resetting needs large otch to cut fracture area, and soft tissue is peeled off extensively, and the complication such as fracture delayed union and disunion, easily appears in destruction blood fortune in various degree.Current internal fixation treatment fracture is converted into lays equal stress on from blindly pursuing anatomical reduction Titanic micro-plates with protecting bone and soft tissue blood to transport to reduce operation wound.
Tibia medial and lateral platform is the articular surface of tibia medial and lateral condyle, and they form joint with femur medial and lateral condyle respectively.Medial tibial plateau is comparatively large, and whole articular surface becomes a concave surface; And outside platform is relatively little and position is slightly high, whole articular surface becomes a convex surface.Fracture of the tibial plateau serious threat is to kneed structure and function.If be used alone plaster fixing 2-3 week more than, obvious ankylosis will be caused.The lower early ambulant of traction can retain motor function but can not realize the reduction of the fracture.Joint compression can cause angulation deformity with metaphysis pulverizing, causes joint over loading to a great extent.Only have articular surface anatomical reduction and keep the limbs line of force, early functional exercise, just can avoid most complication simultaneously.And these requirements can only be realized by early stage open reduction and internal fixtion mostly.Traditional open reduction operating time is long, hemorrhage many, to have an X-rayed number of times more, postoperatively likely there will be the complication such as infection, solid failure, post-traumatic arthritis, malunion, disunion.
The sickness rate of distal tibial fracture is higher, accounts for 31.77% of extremity fracture.Due to the particularity that its wound is dissected, treatment is difficulty comparatively, especially splintered distal tibial factures, the complication such as postoperative easy generation bone does not connect, otch cutaneous necrosis, infection and joint function disturbance.Although External technique treats this type of fracture sometimes also can obtain good effect, long-term fixing can merge pin track infection, locking pin loosens, and has a strong impact on ankle joint function.The tibiofibula stage casing fracture that is applied as of interlocking intramedullary nail brings desirable effect, but for fracture of distal, intramedullary pin technology when involving articular surface of especially fracturing is often fixing not firm, and has fat embolism dangerous.At present, Interal fixation becomes the prefered method for the treatment of distal tibial fracture.Traditional open reduction and Kirschner wire fixation technology is because the primary healing of undue pursuit anatomical reduction, firm internal fixtion and fracture is often to sacrifice fracture site blood fortune for cost, extensive exposure soft tissue and periosteum, often cause the adverse consequencess such as poor wound healing, infection and bone delay in healing.
Along with the development of medical skill, less invasive techniques has entered the every field of medical treatment, and therefore MIPO just becomes the new concept of this type of fracture for the treatment of.MIPO technology comprises utilization fracture Indirect reduction technology, through fracture end both sides minimal incision *, inserts blade plate, give bridge joint across fracture end under adopting subcutaneous or muscle, and to obtain, fracture is relatively stable fixes the far and near section of the fixing fracture of screw.Minimal incision * is light to local soft tissue injury, reduces the damage of fracture surrounding soft tissue and the sanguimotor destruction of fracture end, maintains the biologic activity of sclerite, meet the new ideas of fixing (biologicalosteosynthesis) biology.
Internal fixation steel plate in the market is all formed in one, and shape is comparatively large, and mostly is "T"-shaped for metaphyseal plate profile or " golf club " shape dissection armor plate, more difficult when skin incision inserts subcutaneous.One-body molded internal fixation steel plate must be connected with two panels and above knochenbruch simultaneously simultaneously, inconvenient doctor's operation.Operating time will be brought like this to extend, art district expanded range, soft tissue destruction and the hemorrhage problem increased, add the difficulty of union of fracture and the probability of wound infection.Because the internal fixation steel plate of current Clinical practice is traditional structure, be not suitable for the application of Minimally Invasive Surgery, this steel plate is used not only to be awkward, and greatly reduce the superiority of Minimally Invasive Surgery, not a kind of specially for orthopaedics long bone fracture carries out the steel plate of Minimally Invasive Surgery design up to now, it is very necessary for therefore designing a kind of internal fixation steel plate being suitable for Minimally Invasive Surgery.
