Abstract
The utility model discloses a semispherical extender for a peripheral nerve operation. The semispherical extender comprises an arc extender and a base which is fixedly connected with the arc extender, wherein a plurality of grooves are arranged on the surface of the arc extender and penetrate through the surface of the whole arc extender. The semispherical extender for the peripheral nerve operation, disclosed by the utility model, has the advantages of simple structure, lower cost, simplicity and convenience for use, and convenience for directly sewing up after extending a defect nerve.
Description
Technical field
This utility model relates to a kind of medical apparatus, extender in especially a kind of hemispherical peripheral nerve art.
Background technology
Usually, behind the peripheral nerve injury, the broken ends of fractured bone receive to destroy and cracked, even incision, though inorganization is damaged, the two neural broken ends of fractured bone 1-2cm that also can bounce back.If in early days it is repaired, appoint and so can neural part tractive directly be sewed up.In case the delay operating time, when repairing in the second phase, the tumor that denervates, will form bigger damaged, generally all can be more than 3cm, so the broken ends of fractured bone is difficult under the tension-free situation and sews up.
At present, usually need do neural transplantation clinically and repair the damaged of nerve.The method of neural transplantation is a lot, comprises that the transplanting, allogeneic nerve of autologous nerve transplanted, non-nervous tissue transplants and artificial neuron is transplanted, and in all these methods, except that nerve autograft, all has many problems, like immunological rejection etc.And also there are problems such as two places neural anastomosis mouth and confession bark fetching skin sensory disturbance in nerve autograft.Because peripheral nerve self has the prolongation property of a bit, through the slow prolongation of the neural broken ends of fractured bone, can make neural broken ends of fractured bone length obtain increasing, thereby reach the purpose that shortens damaged neural distance, make damaged nerve can directly sew up reparation.
Therefore, extender can prolong so that directly sew up the problem of damaged nerve to solve the peripheral nerve broken ends of fractured bone in a kind of new hemispherical peripheral nerve art of needs.
Summary of the invention
In view of this, this utility model is devoted to better to solve the peripheral nerve broken ends of fractured bone and can be prolonged so that directly sew up the problem of damaged nerve, has proposed extender in a kind of hemispherical peripheral nerve art.
The technical scheme that this utility model adopts is:
Extender comprises cambered surface extender and the base that is fixedly connected with the cambered surface extender in a kind of hemispherical peripheral nerve art, and wherein, said cambered surface extender surface is provided with many grooves that run through whole cambered surface extender surface.
The camber of above-mentioned cambered surface extender is less than or equal to the radius of ball.
Above-mentioned cambered surface extender is telescopic cambered surface extender, and the harmomegathus ratio is 2: 1.
Above-mentioned base and cambered surface extender are for being tightly connected.
An end face of above-mentioned base is provided with valve.
The beneficial effect of this utility model is:
This utility model is simple in structure, but efficiently solve the perineural broken ends of fractured bone in the art prolonged so that directly sew up the problem of damaged nerve, simultaneously, easy to use and good effect.
Description of drawings
Below with reference to accompanying drawings the specific embodiments of this utility model is explained in more detail, wherein:
Fig. 1 is the structure drawing of device of this utility model;
Wherein, 1-cambered surface extender, 2-base, 3-groove, 4-valve.
The specific embodiment
In order to solve in the neural operation the perineural broken ends of fractured bone in the art is prolonged so that directly sew up the problem of damaged nerve, this utility model provides extender in a kind of hemispherical peripheral nerve art.Next specify extender in this hemispherical peripheral nerve art.
Fig. 1 illustrates the structure drawing of device of this utility model.Extender comprises cambered surface extender 1 and the base 2 that is fixedly connected with cambered surface extender 1 in this hemispherical peripheral nerve art; Wherein, Said cambered surface extender 1 surface is provided with many grooves 3 that run through whole cambered surface extender 1 surface; To the peripheral nerve overtime, the perineural broken ends of fractured bone is placed groove.
The camber of above-mentioned cambered surface extender 1 is less than or equal to the radius of ball, can guarantee that peripheral nerve is in the groove fully.
Above-mentioned cambered surface extender 1 is telescopic cambered surface extender, and the harmomegathus ratio is 2: 1.
Above-mentioned base 2 and cambered surface extender 1 are for being tightly connected.
An end face of above-mentioned base 2 is provided with valve 4, opens valve 4, and extender in this hemispherical peripheral nerve art is continued inflation uniformly; Big to guarantee that cambered surface extender 1 rises uniformly; The neural broken ends of fractured bone is prolonged, keep a period of time, both can directly sew up damaged nerve.
More than the specific descriptions of this utility model are intended to explain the implementation of specific embodiments can not be interpreted as it is restriction this utility model.Those of ordinary skills can make various variants on the basis of the embodiment that details under the instruction of this utility model, these variants all should be included within the design of this utility model.This utility model scope required for protection is only limited by described claims.
Claims (5)
