Description
Technical field
This utility model relates to medical instruments field, especially a kind of inward turning type lower tibiofibula fixture.
Background technology
In daily production, life, normal meeting is because causing the single wound of Inferior tibiofibular joint or associated injury when contingency comprises motion, domestic fixing mainly use lower tibiofibula screw, bolt etc. to this type of damage, there is certain drawback as screw loosening, fracture in lower tibiofibula screw, especially foot walk before namely need to take out screw to avoid screw extraction etc., and strong screw is fixedly unfavorable for the reparation of the physiological healing characteristic of ligament own; And had this type of fixture of lower tibiofibula bolt by cross drilling construction bolt on tibiofibula in the past, tightening nuts fixes, this is fixed on part needs that threaded rod in installation process exceeds nut by the bolt of amputation at exposed bone such as cutting energetically, not only easily cause the mechanical damage in affected part, and operation is comparatively complicated, also have a little exerted bolt part not remove completely, the soft tissues such as abraded skin, bring certain misery to patient.
Utility model content
This utility model aims to provide a kind of mode by threaded rod screw-in connecting rod screw and is fixed, length can according to the built-in free adjustment of tibiofibula transverse diameter of patient's different thicknesses, avoid the amputation operation that threaded rod exposed parts is unnecessary, reduce operation technique fussy degree, simplify unnecessary operation technique, save operating time, removed this device after injury region healing also very convenient, decrease the inward turning type lower tibiofibula fixture of the misery of patient.
For achieving the above object, this utility model provides following technical scheme: inward turning type lower tibiofibula fixture, comprise holder, connecting rod, threaded rod and nut, described holder is made up of elastic rod, cone and boss, wherein cone is located at the two ends of elastic rod, and the junction of elastic rod and vertebral body is provided with boss; Described connecting rod is fixed on the middle part of holder by block plate, and the inside of this connecting rod is provided with screw; Described threaded rod is provided with external screw thread, and this threaded rod screws in the screw on connecting rod, and the front end of this threaded rod is provided with nut, and this nut is fixedly connected with threaded rod, and the rear end of nut is provided with pad, and this pad is fixed on nut.
As further scheme of the present utility model: described cone is triangular pyramid, rectangular pyramid shape, pentagonal pyramid shape or taper shape.
As further scheme of the present utility model: the front end rounding of described nut.
As further scheme of the present utility model: the length of described threaded rod is three times of connecting rod.
Compared with prior art, the beneficial effects of the utility model are: the mode that this inward turning type lower tibiofibula fixture screws in connecting rod screw by threaded rod is fixed, length can according to the built-in free adjustment of tibiofibula transverse diameter of patient's different thicknesses, avoid the amputation operation that threaded rod exposed parts is unnecessary, reduce operation technique fussy degree, simplify unnecessary operation technique, save operating time, remove this device after injury region healing also very convenient, decrease the misery of patient; Holder of the present utility model make use of elastic micro-motion technique for fixing, the tip of two cones on elastic rod embeds in tibia to some extent, can avoid before and after tibiofibula or the displacement of above-below direction too much, reset and lose, operation technique not only Wicresoft but also simple, and be convenient to remove, improve surgical quality, after desmopyknosis, in the patients ' recovery cycle, be worth promoting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
Refer to Fig. 1-2, in this utility model embodiment, inward turning type lower tibiofibula fixture, comprise holder 1, connecting rod 2, threaded rod 3 and nut 4, described holder 1 is made up of elastic rod 1-1, cone 1-2 and boss 1-3, wherein cone 1-2 is located at the two ends of elastic rod 1-1, and this cone 1-2 is triangular pyramid, rectangular pyramid shape, pentagonal pyramid shape or taper shape, and the junction of elastic rod 1-1 and vertebral body is provided with boss 1-3, described connecting rod 2 is fixed on the middle part of holder 1 by block plate 5, the inside of this connecting rod 2 is provided with screw 2-1, described threaded rod 3 is provided with external screw thread, this threaded rod 3 screws in the screw 2-1 on connecting rod 2, the front end of this threaded rod 3 is provided with nut 4, this nut 4 is fixedly connected with threaded rod 3, the rear end of nut 4 is provided with pad 4-1, this pad 4-1 is fixed on nut 4, the front end rounding of this nut 4, nut 4 is convenient to utensil clamping thus turn threaded rod 3, the degree of depth screwing in screw 2-1 by controlling threaded rod 3 regulates the spacing between pad 4-1 and firm banking, the length of threaded rod 3 is three times of connecting rod 2, gap between guarantee nut 4 and holder 1 can narrow down to firmly to be fixed tibiofibula, this existing fixture by nut 4 rotate on threaded rod 3 carry out fastening, fastening complete after needs the threaded rod 3 of outstanding nut 4 is amputated, not only operating difficulties, and easily cause peroneotibial mechanical damage, and this utility model adopts threaded rod 3 to screw in the connected mode of connecting rod 2 inside, threaded rod 3 can not give prominence to nut 4, effectively prevent this problem, reduce operating difficulty.
This utility model in use, first at tibiofibula centre bit drills fixing hole run through, connecting rod 2 passes fixing hole from inside neck outside fibula, and cone 1-2 head inserts in tibia, plays anti-rotation and fixation, then threaded rod 3 is screwed in connecting rod 2, slowly rotary nut 4, boss 1-3 is close to femoral surface, and boss 1-3 is designed to the elasticity that elastic rod 1-1 provides certain, make elastic rod 1-1 and femoral surface reserve gap, the dismounting for device in the future provides convenient simultaneously; Block plate 5 enters fixing hole along with the screw-in of threaded rod 3 thereupon, increases degree before the contacting of stability and elastic rod 1-1, avoids repeatedly the elastic rod 1-1 caused during elastic micro-motion to rupture.
To those skilled in the art, obvious this utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or basic feature, can realize this utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in this utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
