Abstract
The utility model provides a marrow internal round needle for fixing bone fractures. The marrow internal round needle comprises a needle body and is characterized in that a cone body connected with the needle body is arranged at the tail end of the needle body, the diameter of the cone body is two to three times larger than that of the needle body, threads are arranged on the cone body which is connected with a tail end cone body with the diameter being two to three times larger than that of the cone body, and a hexagon groove is formed in a tail end plane of the tail end cone body. The marrow internal round needle has the advantages of being simple in structure, easy to manufacture, convenient and fast during operation, and capable of relieving pains of patients.
Description
Technical field
This utility model relates to the utensil that a kind of medical treatment is used, particularly the designing and making of round needle in a kind of bone marrow of fixedly fracture.
Background technology
Round needle is partes corporis humani position fracture fixer commonly used in the bone marrow, especially the tubular bone that is widely used in extremity long bones in children and adult, such as fracture such as clavicle, ulna, radius, fibulas, but in the operation of current application osseous pin, usually need to or fracture the backshank bending and paste the bone indwelling, bending plasticity difficulty is large.And in the current bone marrow round needle without screw thread, little to the hold of osseous tissue, often have after the operation round needle withdraws from the bone marrow phenomenon or even migration; Backshank exposes harassing and wrecking surrounding tissue and cause pain, and osseous pin also appears in some cases to be withdrawed from and wear out skin and cause infection.
This utility model is developed a kind of interior round needle of bone marrow of fixedly fracture, tail end at the needle body is provided with cone and the tail end cone larger than the needle body, also be provided with screw thread on this cone, can fine round needle in the bone marrow be fixed in the bone marrow, and do not need bending or the backshank that fractures at operation process, alleviate patient's misery.
The utility model content
The purpose of this utility model provides a kind of interior round needle of bone marrow of fixedly fracture, to overcome the deficiency that round needle bone fixation folding exists in the present bone marrow.
In order to realize above-mentioned purpose, round needle in the bone marrow of a kind of fixedly fracture that this utility model provides, comprise needle body 1, concrete technical scheme: the tail end of described needle body 1 is provided with that link to each other with needle body 1 and than the large 2-3 of diameter times cone 2 of needle body 1, is provided with screw thread 3 at cone 2; Described cone 2 also is connected with the large 2-3 of the diameter tail end cone 4 doubly than cone 2; The tail end plane of described tail end cone 4 is provided with hex-shaped recess 5; 1-2 centimeters at the tip 6 of distance needle body 1 also is provided with one section screw thread 7.
Convenient and swift when adopting the manufacturing simple in structure, easy of the utlity model has of above-mentioned measure, operation, can make the lenitive advantage of patient.
Below in conjunction with accompanying drawing to more further detailed explanation of this utility model.
Description of drawings
Fig. 1 is the current interior round needle schematic perspective view of bone marrow;
Fig. 2 is round needle schematic perspective view in this utility model bone marrow.
The specific embodiment
With reference to figure 1, Fig. 1 is round needle schematic perspective view in the current bone marrow, from shown in the figure being the structure of round needle in the current bone marrow, its diameter is the 2-3 millimeter, and length is the interior round needle of 20-30 centimetre bone marrow, in the operation process of fixing fracture, need to the backshank bending is bent, reach fixing bone marrow.
With reference to figure 2, Fig. 2 is round needle schematic perspective view in this utility model bone marrow, clearly from figure find out that this utility model comprises needle body 1, specific embodiments: the tail end of this needle body 1 is provided with that link to each other with needle body 1 and than the large 2-3 of diameter times cone 2 of needle body 1, is provided with screw thread 3 at cone 2; This cone 2 also is connected with the large 2-3 of the diameter tail end cone 4 doubly than cone 2.
The diameter of needle body 1 of the present utility model is generally the 2-3 millimeter, and length is generally 20-30 centimetre, strengthens cone 2 and tail end cone 4, and purpose is that the interior round needle of bone marrow is fixed in the bone marrow better, and operation process does not need bending or the backshank that fractures.
The tail end plane of tail end cone 4 of the present utility model is provided with hex-shaped recess 5, and in operation process, the hexagon wrench of available dedicated inserts in the hex-shaped recess 5, insertion or the taking-up of round needle in the control bone marrow.1-2 centimeters at the tip 6 of distance needle body 1 also is provided with one section screw thread 7, and purpose is to make that round needle is fixed in the bone marrow more firm in the bone marrow.
This utility model is made round needle in the bone marrow of various different lengths, selects as required round needle in the bone marrow of different length in operation.
Claims (2)
1. fix round needle in the bone marrow of fracturing for one kind, comprise needle body (1), it is characterized in that: the tail end of described needle body (1) be provided with link to each other with needle body (1) and than the large 2-3 of diameter of needle body (1) cone (2) doubly, be provided with screw thread (3) at cone (2); Described cone (2) also is connected with the large 2-3 of the diameter tail end cone (4) doubly than cone (2); The tail end plane of described tail end cone (4) is provided with hex-shaped recess (5).
