Abstract
A tibiofibula fracture dermal toxicity drawing screw angle guider is characterized in composed of an angle muffle, a muffle core, and a drill sheath, wherein the angle muffle is provided with a handle, the end of the angle muffle contacted with bone is in micro saw tooth shape, while the end angle is 30-75 degrees and 90 degrees, the muffle core is solid engaged with the inner diameter of the angle muffle, the outer diameter of the drill muffle is engaged with the inner diameter of the angle muffle, which inner diameter has different standards and the end angle is same as the angle muffle. The utility model has small wound, simple operation, shortened surgery time, and reliable fixation.
Description
This utility model belongs to medical apparatus and instruments, the guider that particularly a kind of internal fixation of fracturing is used.
Fracture of tibia and fibula is one of the most common clinically fracture, and operation method is more, and therapeutic effect is different.Traditional operation method is open reduction, internal fixation mode.Wound face is bigger, and periosteum and soft tissue injury are big, and patient is not only painful big, and wound and union of fracture are slow.Along with the variation of AO school viewpoint, operation method changes to BO: promptly reduce wound to the greatest extent to greatest extent, protection fractures blood circulation.Therefore, fracture internal fixation mode need change.The purpose of this utility model is to adapt to new fracture operation method, and a kind of fracture of tibia and fibula percutaneous lag screw angle guideline is provided, and realize internal fixation of fracture, and wound face is little, and union of fracture is fast.
Fracture of tibia and fibula percutaneous lag screw angle guideline of the present utility model, it is characterized in that comprising angle sleeve, sleeve core, drill bushing, have handle on the angle sleeve, angle sleeve and surface of bone contact jaw are little zigzag, end plane angle 30～75 degree and 90 degree, sleeve core are that solid shape and angle sleeve diameter coincide, and drill bushing external diameter and angle sleeve diameter coincide, its internal diameter has different size, and end plane angle is identical with the angle sleeve.
The telescopic end plane angle of described angle is a kind of model from 30～75 degree every 5 degree.
Described angle sleeve non-with the surface of bone contact jaw be sleeve cap, an end of corresponding sleeve core, an end of drill bushing are respectively cover pole cap, drill bushing medicated cap.Main like this is for easy to operate.
According to peroneotibial situation, described drill bushing internal diameter generally has 4.5 millimeters, 3.2 millimeters two kinds of specifications, relatively 9 millimeters of Shi Yi angle sleeve outer diameter, 8 millimeters of internal diameters.
For operational convenience, described handle is preferably movable.
Below in conjunction with the embodiment description of drawings:
Fig. 1 is an angle tube-in-tube structure sketch map of the present utility model;
Fig. 2 is a sleeve cored structure sketch map;
Fig. 3 is the drill bushing structure sketch map;
Fig. 4 is the handle arrangement sketch map.
Among the figure: 1 handle, 2 sleeve cap, 3 cover pole caps, 4 drill bushing medicated caps
Have handle 1 on the angle sleeve, itself and surface of bone contact jaw are little zigzag, and angle is a model from 30～75 degree every 5 degree, and other has 90 degree models, and each model is selected to use according to fracture situation.The line of can marking on the terminal sleeve cap 2, as mark, convenient and drill bushing coupling.Handle is movable, convenient operation, and its shape can be as shown in Figure 4.The angle sleeve does not comprise the sleeve cap part, long 50 millimeters of center, 9 millimeters of external diameters, 8 millimeters of internal diameters.
The sleeve core is solid shape, and its external diameter and angle sleeve diameter coincide, and the comparable angle sleeve of length is a little slightly long.
Drill bushing external diameter and angle sleeve coincide, and internal diameter is divided into 4.5 millimeters and 3.2 millimeters two kinds, and front end also is little zigzag, and angle and angle sleeve are complementary.
Operational approach:
At C arm machine-bone surgery traction table reduction maneuvers reduction fracture of tibia and fibula, make every effort to anatomical reduction.According to plan and X-ray surveillance scenarios before the detailed art, select percutaneous to go into a little, through periosteum enters the mouth about 1～1.5 centimetre.During operation, the sleeve core retainer plate is gone in the angle sleeve, the telescopic sawtooth of angle is extracted the sleeve core out with after surface of bone closely contacts, and is replaced by drill bushing.Earlier be 4.5 centimetres drill bushing with internal diameter, the nearside cortical bone is a sliding eye, and then to be replaced by internal diameter be 3.2 centimetres drill bushing, with 4.5 centimetres of supporting screw tap tapping, is screwed into 4.5 millimeters AO cortex screws after the depth measurement of offside cortical bone brill tapping hole, and inlet can stitch 1 pin.The protection of postoperative Gypsum Fibrosum.
Advantage of the present utility model:
1, the utility model has been realized fixing in the percutaneous pinning, has overcome the wound harm that open reduction brings, the wound utmost point Little, can claim " keyhole " operation, the utility model has solved percutaneous pinning, the unclear difficult problem of exposure of surgical field.
2, the utility model need not peeled off periosteum, has protected to greatest extent the blood fortune of periosteum and soft tissue hinge, and is short Advanced the healing of fracture.
3, the utility model has solved the problem that traditional pulling force nail only has open reduction to use, through the skin lag screw together Sample can reach the pressurization fixed effect of open reduction.
4, the angle of angle sleeve and drill bushing and sawtooth the design, can with surface of bone close contact, no skidding. Movable Handle can be convenient to the operation of operator's all directions.
In a word, it is little, easy and simple to handle to the utlity model has wound, during desmopyknosis, and fixing reliable characteristics, fully symbol Close the up-to-date viewpoint of BO Wicresoft. Be applicable to closed tibiofibular fractures, mainly be applicable to oblique fracture (angle＞30 Spend) and the screw type fracture.
Claims (6)
1, a kind of fracture of tibia and fibula percutaneous lag screw angle guideline, it is characterized in that comprising angle sleeve, sleeve core, drill bushing, have handle on the angle sleeve, angle sleeve and surface of bone contact jaw are little zigzag, end plane angle 30～75 degree and 90 degree, sleeve core are that solid shape and angle sleeve diameter coincide, and drill bushing external diameter and angle sleeve diameter coincide, its internal diameter has different size, and end plane angle is identical with the angle sleeve.
2, guider according to claim 1 is characterized in that the telescopic end plane angle of described angle from 30～75 degree, is a kind of model every 5 degree.
