Description
Technical field
The present invention relates to a kind of medical treatment device, especially lower tibiofibula is united the fine motion fixture of healing.
Background technology
In daily production, life; can cause the simple wound of lower tibiofibula associating or associated injury in the time of usually can comprising motion because of contingency; the domestic fixing main lower tibiofibula screw that uses; so there are certain drawback such as screw loosening, fracture; especially namely need take out screw to avoid screw extraction etc. before walking under the foot; and screw fixedly is unfavorable for the reparation of the physiological healing characteristic of ligament own; only have elastic micro-motion to fix and just can reach this purpose; so abroad began in recent years the development that turns to elastic micro-motion fixing, the domestic application ﹠ design that also touches.Present existing elastic micro-motion technique for fixing: the predictable weak point of first kind stitching thread (Suture) compression device in front and back or above-below direction have to a certain degree displacement, there is report lower tibiofibula may occur abroad and unites to reset and lose, cause shakiness thereby affect to a certain extent Ligament healing.And this button stitching thread to be set with present price more expensive, to ordinary populace popularization shortcoming, therefore still be fixed as mainstream market with os integumentale screw; Equations of The Second Kind: take shackle as agent structure, although the lower tibiofibula shackle has certain elasticity, meet B﹠J flexible fastening biology principle, this apparatus structure and shackle are fixing and remove all inconvenience of operation, and skin incision is larger, uses clinically few.For these shortcomings, the purpose of this device invention is exactly to design the fine motion flexible fastening that can avoid lower tibiofibula to unite resetting and lose, elastic micro-motion can make the Ligament healing of damage for meeting the physiology mass property, satisfy the drawback that need not before walking under the foot to perform the operation and take out, low price, popular acceptance, but popularization had, and satisfy the simple principle of operation technique.。
Summary of the invention
The objective of the invention is: a kind of lower tibiofibula elastic fixing device is provided, it has the B﹠J of meeting flexible fastening biology principle, the front drawback that needs operation to take out of avoiding walking under the foot, low price, have and install and remove conveniently, the characteristics of skin incision Wicresoft.
The present invention is achieved in that a kind of lower tibiofibula bolt elastic fixing device, and its special different part is: comprise elastic rod, be arranged on cone, connecting rod and the nut at elastic rod two ends;
Described cone is vertical with elastic rod, and described connecting rod one end is fixedly connected with the middle part of elastic rod, the other end is provided with external thread part; Described nut and external thread part screw togather.
Described a kind of lower tibiofibula bolt elastic fixing device, its special character is: also comprise a pad, described pad is arranged on the external thread part, and pad one end face cooperates with the end face of an end of nut.
Described a kind of lower tibiofibula bolt elastic fixing device, its special character is: described pad is fixedly connected with nut one end and one-body molded making, the other end rounding of nut.
Described a kind of lower tibiofibula bolt elastic fixing device, its special character is: the other end rounding of described nut.
Described a kind of lower tibiofibula bolt elastic fixing device, its special character is: described cone is rhizoma sparganic taper or rectangular pyramid shape.
Described a kind of lower tibiofibula bolt elastic fixing device, its special character is: there is boss described elastic rod and cone junction, and described boss is towards nut.
Described a kind of lower tibiofibula bolt elastic fixing device, its special character is: there is block plate at the middle part of described elastic rod, and connecting rod is fixedly connected with block plate.
A kind of lower tibiofibula bolt of the present invention elastic fixing device owing to adopting such structure, during use, connects the tunnel with drill bit in the middle of tibiofibula, connecting rod passes through tunnel, and external thread part and the nut of connecting rod screw togather; The tip of two cones on the elastic rod embeds in the tibia to some extent, can avoid the displacement of tibiofibula front and back or above-below direction too much, reset and lose, operation technique is Wicresoft but also simple not only, to improving the operation quality, shorten operating time, reduce intraoperative hemorrhage, the patients ' recovery cycle has great value after the desmopyknosis.
Description of drawings
Fig. 1 is front view of the present invention.
Fig. 2 is the front view of user mode of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of lower tibiofibula bolt elastic fixing device, it comprises elastic rod 1, is arranged on the cone 2 at elastic rod 1 two ends, connecting rod 3 and nut 4;
Described cone 2 is vertical with elastic rod 1, and described connecting rod 3 one ends are fixedly connected with the middle part of elastic rod 1, the other end is provided with external thread part 31; Described nut 4 screws togather with external thread part 31.There is block plate 11 at the middle part of described elastic rod 1, and connecting rod 3 is fixedly connected with block plate 11.
Also comprise a pad 5, described pad 5 is arranged on the external thread part 31, and pad 5 one end faces cooperate with the end face of an end of nut 4.
Described pad 5 is fixedly connected with nut 4 one ends and one-body molded making, the other end rounding 41 of nut 4.
Described cone 2 is rhizoma sparganic taper, rectangular pyramid shape, pentagonal pyramid shape or taper shape.
Described elastic rod 1 has boss 6 with cone 2 junctions, and described boss 6 is towards nut 4.
The present invention as shown in Figure 2, makes a call to one with bit bore from the fibula outside to the posterior aspecct of the tibia direction first and connects the tunnel in use in the middle of tibiofibula, pass through tunnel in connecting rod 3 outside from the posterior aspecct of the tibia to the fibula, and external thread part and the nut of connecting rod 3 screw togather.Cone 2 heads slowly insert in the tibia 7, play anti-rotation and Stabilization, along with nut is tightened, because tibia 7 inner surfaces are inclined-planes, far-end is thick, and the cone 2 of far-end 71 contacts first tibia 7 inboards and inserts sclerotin, it is curved that elastic rod 1 begins to become, and then tibia 7 surfaces are close on the plane of boss 6.The design of boss 6 can provide certain elasticity for elastic rod.Block plate 11 can increase the intensity that contacts of stability and elastic rod also along with the propelling of screw rod can enter the tunnel with screw rod simultaneously, and elastic rod 1 possible in the time of can avoiding repeatedly elastic micro-motion to a great extent ruptures, and can lay the groundwork for elastic micro-motion on the other hand.Along with nut tighten tibia 7 inner surfaces produce when the ankle joint flexion and extension the responsive to axial force of screw rod under the basic distal side of contact resilient bar 1 and connecting rod 3 junctions, its proximal lateral is because tibia 7 surfaces become diagonal and connecting rod to form an angle, one fixed gap is arranged, comprise that the cone 2 of near-end 72 of opposite side is because basically to be subject to the pulling force of screw rod large not as the cone 2 of far-end 71, only small part is inserted sclerotin, reserve certain space, can realize elastic micro-motion when so far this device is for ankle moving in the future.At last external thread part 31 is exposed the external thread part screw rod amputation of fibula 8 outside nuts.
Wherein the thickening of boss 6 can have certain space with tibia 7 surfaces, has both supplied certain oligodynamics, also provides convenience for the taking-up of day posterior pyramids.
Above-described only is preferential embodiment of the present invention.Should be pointed out that for the person of ordinary skill of the art, in the situation that do not break away from the principle of the invention, can also make some improvement and modification, this also is considered as protection scope of the present invention.
