The utility model solves the troubles that the steel plate is used for curing the fracture of the femur in the orthopedic surgery is easy to be broken and bent, and the fracture is not cicatrized or cicatrized differently, and the prior external fixation holder of the fracture of the tibiofibula has hulking volume, thereby affecting the beauty and going against movement, and the stress shading affects the cicatrisation of the fracture. So the utility model is suitable for being generalized and used in the hospitals, in particular to the primary-level hospitals.
Description
Technical field this utility model relates to a kind of medical apparatus and instruments, is that Orthopeadic Surgery is used for the treatment of between fracture of shaft of femur, fracture of tibia and fibula, tuberosity and the inside and outside fixture of subtrochanteric fracture---the non-stress shielding fixedly device of pressurization combination type that slides.
Background technology is present, mainly adopts the operative treatment of intramedullary needle, compression steel plate according to " AO " theoretical treatment fracture of shaft of femur, in the femoral shaft, the operative treatment of 1/3 compression steel plate to be generally to be accepted down.Find that from nearly 30 years both at home and abroad clinical practice it is a lot of that steel plate bending, fracture, bone does not connect or malunion case appear in postoperative, have the bibliographical information can be up to 40%.Wherein compression steel plate self accounts for pith because of design reasons, secondly is because operate miss causes.Occurred " BO " notion biology in recent years, designed steel plate still can not be realized early stage static fixation, in, the pressurization of sliding of the power in late period, this steel plate is not applied to the treatment of femoral shaft at present as yet.
The summary of the invention the purpose of this utility model is in order to solve Orthopeadic Surgery treatment fracture of shaft of femur stress shielding, under the steel plate osteoporosis, steel plate fracture, bending, nonunion, delayed union and the bulky influence of the external fixer activity attractive in appearance, unfavorable of fracture of tibia and fibula at present, stress shielding influences difficult problems such as union of fracture, and a kind of inside and outside fixture of bone surgery treatment is provided---and non-stress shielding slip pressurization combination type is device fixedly.
This utility model non-stress shielding slip pressurization combination type is the device content Description fixedly:
This utility model non-stress shielding slip pressurization combination type is device fixedly, it is characterized in that: can make the non-stress shielding slip and add pressure combined inner fixer, non-stress shielding slip pressurization combinable external fixator and three kinds of forms of non-stress shielding slip pressurization inclined hole external fixator;
Non-stress shielding slides and to add the support body that pressure combined inner fixer is the bridge shape of being made by steel plate, and dividing up and down, two parts are upper frame and lower frame; The connection of last lower frame is to be slidingly connected, the junction of upper frame is one to have the cylinder of endoporus, the junction of lower frame is one to have the cylinder of keyway, can axially slide up and down the location in the hole of upper frame, fixes and prevents that lower frame from endwisely slipping by the bolt pin; 2～3 parallel tapping screws are set respectively on the upper and lower support body of bridge shape support body;
The slide junction of upper frame of pressurization combinable external fixator of non-stress shielding is that the junction of a square body that has a convex endoporus, lower frame is one to have the square body of groove, the connection of last lower frame is axially sliding up and down connection by the square body that has groove of lower frame junction in the square body that has the convex endoporus of the junction of upper frame, fix and prevent that lower frame from radially sliding by peg; 2～3 parallel tapping screws are set respectively on the upper and lower support body of bridge shape support body, fastening by the interior hexagonal holding screw of a side;
Non-stress shielding slip pressurization inclined hole external fixator is made up of upper frame and lower frame two parts, and the connection of last lower frame is to fix by two pieces of bolt pins, and for preventing that lower frame from radially sliding, fastening by the holding screw that the support body side is provided with; Front end at upper frame is provided with the diclinic hole, 2 pieces of broken forcing screws of self tapping penetrate inclined hole, fastening by the holding screw that the upper frame side is provided with, rear end at lower frame also is provided with the diclinic hole, and 2 pieces of steinman pins penetrate fastening the combining of holding screw that the inclined hole of rear end also is provided with by the support body side.
This utility model non-stress shielding slip pressurization combination type is device fixedly, solved Orthopeadic Surgery treatment fracture of shaft of femur stress shielding, the osteoporosis steel plate fractures under the steel plate, crooked, nonunion, the bulky influence of external fixer of delayed union and present fracture of tibia and fibula is attractive in appearance, unfavorable activity, stress shielding influences difficult problems such as union of fracture, being slidingly connected of the chute combination that the junction of last lower frame is provided with, realized the pressurization that endwisely slips under prerequisite without spin, the bolt pin that control on chute is slided, can be comminuted fracture provides static fixation control to slide in early days, after relatively stable 8 weeks of fracture, can pull out the bolt pin, realize that myotasis and action of gravity power down pressurizes and without spin.This utility model is the combination of collection intramedullary pin interlocking static fixation and the fixed theory of mechanics of external fixer slip pressurization; support body design by bridge shape; the point contact can realize protecting to greatest extent periosteum and soft tissue blood fortune; meet fixing theory current " BO " biology, be combined into all lengths and be fit to hypomere multistage complicated fracture in the femoral shaft.The sliding connection structure without spin of lower frame in the employing, the suffered tensile antagonism of support body self is better than any compression steel plate of use at present, another function of bolt pin is the bone fixation folded block but it controls in axial sliding, but plant bone mass between the bone fixation broken line also, effective bone grafting damaged to the outside cortex of fresh fracture or old fracture has fixation.Tapping screw reduces operation sequence, shortening operating time is under " BO " biology, fixedly theory instructed, mechanical property the best, really can realize the external fixator of inner fixer, fracture of tibia and fibula and the intertrochanteric fracture of fixing optimal fracture of shaft of femur biology, because of having the characteristics of the pressurization of sliding without spin, requirement to the reduction of the fracture can suitably be relaxed, and fixing complicated syntripsis is had more clear superiority the operative failure rate is obviously reduced.Non-stress shielding slide the inclined hole support body of pressurization inclined hole external fixator be the spininess locating guider be again holder, the accurate fixing-stable of threading a needle, pin-nail crossings on different level, thread a needle along the tension force compression trabeculae, can effectively resist the complex stress of fracture end, spininess concentrates on tuberosity part, above-knee nothing is threaded a needle, be beneficial to patient's early ambulant, knee joint movable function is not had influence, realize elasticity and add press fit.Be fit to hospitals at different levels, especially basic hospital is applied.
