Description
Technical field
This utility model relates to orthopedic, the care device of A61F in a kind of International Classification of Patents A portion, particularly relates to a kind of Osteological treatment of strephopodia or ankle and foot complicated fracture or exterior fixation bracket apparatus of rehabilitation of being used for.
Background technology
Strephopodia and equinvoarus are clinical modal deformities in the lower limb malformation, its complex genesis, and type is various.The characteristics of equinvoarus be receive in the sufficient first half, in turn over, turn in the calcaneus, the sole of the foot is bent, contracture of Achilles tendon is Horse hoof deformity etc.The neonate sickness rate is 1 ‰～4.5 ‰, and men and women's ratio is 2:1, and is one-sided more than bilateral.This old complaint can be divided into congenital, posteriority according to pathogenic factor; Can find deformity after the congenital talipes equinovarus birth, therefore diagnosis is not difficult; The posteriority equinvoarus generally can be caused by diseases such as cerebral palsy, spina bifida, wounds.If early stage suitably processing, then great majority can obtain to correct preferably curative effect; If do not treat, then will be maimed throughout one's life, influence live and work.
Exterior fixation bracket is a kind of external fixture, directly do not contact human body skin, fracture or the maleformation assembling different support arm configuration different according to human body, act on local skeletal sites by threading a needle the one or more stringer bar (pipe) outside each end of fracture and the skin in the bone and/or encircling to be connected, reach the plane, three-dimensional rack is fixed, thereby play stable, reset, pressurization or drawbar extension, be corrected to the odd-shaped effect in angle, and then play auxiliary union of fracture or correct odd-shaped therapeutical effect.Existing numerous fracture or cacomelia patient use the back limbs to obtain rehabilitation or rectification.For the pathologisch Bruch due to bone tumor, chronic osteomyelitis, tuberculosis and other osteopathia, methods such as the traction of tradition bone, external plaster fixation are handled very difficulty, can avoid focal zone with external fixed support for bone, the external fixation of threading a needle outside focal zone helps the reparation that focal zone is handled through treatment.
Disclosed related application for example, application number 201020165959 discloses a kind of orthopaedics fixed mount, form by support body and locking pin, wherein support body is cylindric, the support body both ends of the surface are annular fixed mount, the annular fixed mount has symmetric arcuate socket, be provided with four parallel support body support bars in the arcuate socket of annular fixed mount, support body support bar end has screw thread, hold-down nut is located the support body support bar in annular fixed mount both sides, also be provided with the locking pin gim peg in the arcuate socket of annular fixed mount, nut is located the locking pin gim peg in the both sides of annular fixed mount, and the locking pin gim peg other end is the locking pin installation end.CN200420039115.3 orthopaedics external fixer and for example, it comprises body frame, locking pin, T-shape sleeve, and body frame is divided into three parts, and the body frame middle part is the telescopic adjustment section, and the body frame both sides are the locking pin construction section; The telescopic adjustment section is divided into two parts, wherein a part has core bar, another part and core bar are held in opposite directions and are designed to sleeve structure, core bar places sleeve pipe and cooperatively interacts, core bar has elongated slot, and a side of elongated slot has the bar shaped tooth, and elongated slot is built-in with the displacement gear that matches with bar shaped in the groove, displacement gear middle part hollow out becomes through hole, and through hole is built-in with pin; Have through hole on casing wall, lead to the hole site is corresponding with the position of core pole gain, and through hole is built-in with annular retainer ring, and retainer ring is built-in with the interlock sleeve pipe, and pin partly penetrates in the interlock sleeve pipe.
Lopsided orthopedic for the strephopodia complexity, there is the long-time fixedly often limited problem of posterior joint activity of correcting in like product in the market.
Summary of the invention
The purpose of this utility model provides a kind of exterior fixation bracket that meets the anatomical physiology feature of ankle, arch of foot, wears the supporting use of metal spicule in by bone at distal tibial, calcaneus and arch of foot and forces to correct realizing.
Realize that goal of the invention measure of the present utility model is: be interconnected to constitute by main part, basic connector, multidirectional connector, joint device, actuator, securing member, auxiliary member, connecting hole is arranged on the main part, main part is loopful, semi-ring, connect with basic connector or multidirectional connector, or be connected with the joint device to add voltage regulator, the metal spicule is fixed on the main part with securing member.
This utility model has pressurization, reduction by traction, drawing-off to prolong, comprehensive adjusting, multiple efficacies such as orthopedic.
Advantage of the present utility model is that at first, osteotomy surface both can be stablized in many planes, multi-direction fixing, and control and adjustment axis impose the traction compression stress to fracture end and promote knitting, can be used to receive just becoming angle, rotation and lateral displacement deformity again.Secondly, at the fixing problem of posterior joint limitation of activity of the long-time rectification of like product in the market, the design of this project innovation multiple joint device with elasticity join dependency parts, after having adopted this technology, flexible fastening ankle joint especially can be regulated as required, keeps the maximum activity degree in joint, so few side effects, complication is few.Once more, can select the assembly arbitrary load of suitable specification to become not isomorphism type according to fracture, lopsided type and position.In addition, on raw material, select mechanical performance higher, lightweight superduralumin kirsite 7A04 or titanium alloy TC 4 for use.Mainly be applicable to the external fixation operation of strephopodia or ankle and foot opening, complicated fracture.
