Abstract
The utility model relates to an inner fixing device for the fracture of a long bone in an orthopaedics operation, which is composed of a steel plate, plate arms and screws. The two sides of the steel plate are enclasped with two to six pairs of plate arms. The plate arms are in a bracket shape and are equidistantly separated in mutual symmetry. The two sides of each plate arm are both provided with teeth. The head end and the tail end of the steel plate are respectively provided with one to three holes provided with the screws. The material of the product adopts nickel-titan-shaped memorial alloy. The utility model can reset long bone fracture by contraposition with rotation resistance and shortening resistance. The fixation is reliable and effective. The utility model can be conveniently assembled and disassembled in a human body.
Description
This utility model relates to long bone fracture internal fixation apparatus in a kind of bone surgery, is in particular a kind of shape memory sawtooth armlet and embraces compound compression steel plate.
The fracture of human limb long bone is more and more sees, also more and more serious.Especially in the technique for fixing that resets of comminuted fracture, the scheme that sure therapeutic effect is arranged that Shang Weiyou is satisfied.So the long bone comminuted fracture is the difficult point and the research focus of orthopaedics always.In the technique for fixing that resets of the treatment long bone fracture of using at present, with the wounded's requirement and doctor's skill level in conjunction with and determine.Advantage as exterior fixation bracket is the sanguimotor further destruction of not increasing the weight of fracture region, but Chang Yi causes pin track infection, nursing trouble, daily life inconvenience.How common intramedullary pin can not influence healing, but can not prevent rotation, the shortening displacement of comminuted fracture.Interlocking intramedullary nail can prevent rotation, shorten displacement, but stress shielding can cause nonunion.The general steel plate screw resets and fixes, but wound is big, taking-up bothers, easily cause stress shield, easily broken steel plate and screw, and union of fracture Chang Kejian postpones or disunion.Normal tape tooth arm frame-type is encircled and can not be anti-rotation and shorten, and it is invalid to fix sometimes.
The purpose of this utility model be to provide a kind of can para-position to line reset long bone fracture, especially comminuted fracture, can anti-rotation, anti-ly shorten again, shape memory sawtooth armlet is embraced compound compression steel plate in the fixing reliable and effective long bone fracture.
This utility model is achieved in that it is made of steel plate, plate arm and screw, and the steel plate both sides encircle 2～6 pairs of plate arms, the plate arm is bracket, equidistant apart and symmetrical mutually, and plate arm both sides are equipped with tooth, steel plate head, tail two ends respectively are provided with 1～3 hole, and the hole is provided with screw.Steel plate, plate arm and screw are made by nickel-titanium shape memory alloy material.
Be described in detail this reality is novel below in conjunction with drawings and Examples.
Fig. 1 is the front schematic view of this utility model.
Fig. 2 is the side schematic view of the removal screw of this utility model.
Consult shown in each accompanying drawing, this utility model is made of steel plate 1, plate arm 2 and screw 3, and steel plate 1 both sides encircle six pairs of plate arms 2, plate arm 2 is bracket, equidistant apart and symmetrical mutually, and plate arm 2 both sides are equipped with tooth 4,1 of steel plate, tail two ends respectively are provided with two holes 5, and hole 5 is provided with screw 3.
Size of the present utility model, shape, quantity are according to using the position different and different.Its material selection niti-shaped memorial alloy of steel plate, plate arm and screw only needs the adjusting by the less temperature difference, can control the shape of this equipment with using freely, and is all very convenient in the dismounting of the intravital installation of people.
Niti-shaped memorial alloy is in light weight, intensity is high, anti-corrosion, endurance, bending resistance, anti-twist, has excellent biological compatibility with human body.Particularly special is that it has special memory performance to self geometry, in 0～5 ℃ of frozen water, can change its shape, launch its tooth arm, be convenient to install, when temperature is raised to more than 36 ℃, can be returned to original geometry rapidly, be convenient to install and fix fracture site.
In addition, this utility model increases by 2～6 pairs of toothed arms to encircle the osteocomma of pulverizing on the basis of former steel plate, does not need to fix with wire binding in addition, has saved operating time.The inner face of arm and the tooth of both sides then are convenient to arm and the plate place can not oppress periosteum and blood vessel, avoids downright bad and the influence healing.The more important thing is that steel plate prolongs to two ends, press the length and the size of bone, design 1～3 hole, so that mounting screw, with rotation and the shortening displacement that prevents comminuted fracture.
Installation method: after pressing the corresponding specifications and models this utility model product of the correct selection of fracture site and reason, sterilization, immerse in 0～5 ℃ of sterilization frozen water, according to bone footpath size, launch to encircle arm with strutting pincers, exposure place of dislocation fracture, an end is fixed in the warm water gauze elder generation hot compress about 50 ℃, after reaching good anatomical reduction, hot compress remainder again.If somewhere arm, tooth portion or the corresponding surface of bone of board shape incompatibility, then ice water compress unclamps, and reshaping of hot compress gone up for another example and installed, and under the para-position situation good to line, the screw at two ends is installed again.
Removing method: after exposing this utility model product, take out screw earlier, cold compress such as aseptic ice bag of reuse or ice cube, this utility model product launches automatically, can take out.
