Abstract
This utility model relates to a kind of Kirschner wire, described Kirschner wire is provided with syringe needle, spheroid and shank, described syringe needle is provided with screw thread, described syringe needle and spheroid pass through together with laser weld, described shank and spheroid pass through together with laser weld, described syringe needle and shank are on same straight line, and described needle tip is triangular pyramid or polygonal pyramid shape.Its advantage shows: syringe needle of the present utility model is provided with screw thread, possesses good hold, can avoid the accidental movement of sclerite and Kirschner wire; This utility model is also provided with spheroid, different from the distance of needle tip according to spheroid, is provided with different models, can control depth of needle, prevents inserting needle from excessively deeply causing the damage of nerve, blood vessel and soft tissue; Kirschner wire passes fixing sclerite via the nail of bone-fracture fixation steel plate, utilizes the feature that Kirschner wire spheroid is larger than bone-fracture fixation steel plate nail, can be temporarily fixed on skeleton by bone-fracture fixation steel plate, be convenient to next step operation technique.
Description
Technical field
This utility model relates to a kind of medical apparatus, specifically, relates to a kind of Kirschner wire.
Background technology
Kirschner wire is internal fixation material conventional in a kind of bone surgery, and its length is generally at 150-200mm, and diameter, between 0.5-2mm, has different several specifications, is usually used in the long-term fixing of the temporary fixed or less sclerite of sclerite in performing the operation.Because common Kirschner wire is ganoid column structure, hold is less, and the situations such as easy appearance loosens, displacement, cause the reduction of the fracture to be lost; If Kirschner wire inserting needle is excessively dark, then may injured blood vessel, nerve.
Chinese patent application: CN201110282650.6, disclose a kind of Kirschner wire with dog hole, the afterbody of described Kirschner wire is hook-shaped, can hook the terminal of little sclerite tendon, strengthen fixed effect, but the less and uncontrollable paracentesis depth of this Kirschner wire hold.About paracentesis depth being controlled and the Kirschner wire of good fixing effect, yet there are no report.
Summary of the invention
The purpose of this utility model is, provides a kind of Kirschner wire.
For achieving the above object, the technical scheme that this utility model is taked is:
A kind of Kirschner wire, described Kirschner wire is provided with syringe needle, spheroid and shank, described syringe needle is provided with screw thread, described syringe needle and spheroid pass through together with laser weld, described shank and spheroid pass through together with laser weld, described syringe needle and shank are on same straight line, and described needle tip is triangular pyramid or polygonal pyramid shape.
The diameter of described syringe needle is 1.2-2.0mm, and the pitch of described screw thread is 0.5mm, and the diameter of described spheroid is 3-5mm, and the diameter of described shank is 1.2-2.0mm, and the total length of described Kirschner wire is 140-180mm.
This utility model advantage is:
1. syringe needle of the present utility model is provided with screw thread, possesses good hold, can avoid the accidental movement of sclerite and Kirschner wire.
2. this utility model is provided with spheroid, different from the distance of needle tip according to spheroid, is provided with different models, can control depth of needle, prevents inserting needle from excessively deeply causing the damage of nerve, blood vessel and soft tissue.
3. Kirschner wire is via the nail of bone-fracture fixation steel plate through fixing sclerite, utilizes the feature that Kirschner wire spheroid is larger than bone-fracture fixation steel plate nail, can be temporarily fixed on skeleton by bone-fracture fixation steel plate, be convenient to next step operation technique.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of this utility model Kirschner wire.
Accompanying drawing 2 is use schematic diagrams of this utility model Kirschner wire.
Accompanying drawing 3 be this utility model Kirschner wire and bone-fracture fixation steel plate with the use of schematic diagram.
Detailed description of the invention
Also with reference to accompanying drawing, this utility model is further described below in conjunction with embodiment.
The Reference numeral related in accompanying drawing and ingredient as follows:
1. syringe needle 11. screw thread
2. spheroid 3. shank
4. key 41. ossiculum blocks
5. bone-fracture fixation steel plate.
Embodiment
Please refer to Fig. 1, Fig. 1 is the structural representation of this utility model Kirschner wire.Described Kirschner wire is provided with syringe needle 1, spheroid 2 and shank 3, described syringe needle 1 is provided with screw thread 11, described syringe needle 1 top is triangular pyramid, described syringe needle 1 and spheroid 2 pass through together with laser weld, described shank 3 passes through together with laser weld with spheroid 2, and described syringe needle 1 and shank 3 are on same straight line.
It should be noted that, described syringe needle 1 top also can be polygonal pyramid shape; Different according to spheroid 2 and syringe needle 1 top distance, Kirschner wire is provided with different models; The diameter of described syringe needle 1 is 1.2-2.0mm, the pitch of described screw thread is 0.5mm, the diameter of described spheroid 2 is 3-5mm, the diameter of described shank 3 is 1.2-2.0mm, the total length of described Kirschner wire is 140-180mm, above specification is the optimum size that inventor draws according to Long-term clinical experience, should not be considered as this area routine techniques means.
Please refer to Fig. 2 and Fig. 3, Fig. 2 is the use schematic diagram of this utility model Kirschner wire, Fig. 3 be this utility model Kirschner wire and bone-fracture fixation steel plate with the use of schematic diagram.According to the situation of patient during use, select the Kirschner wire of suitable model, by electric drill, Kirschner wire is punctured into bone, ossiculum block 41 and key 4 are fixed, when spheroid 2 touches key 4 time, whole Kirschner wire cannot continue deeply, can avoid the damage of nerve, blood vessel and the soft tissue deeply caused because puncturing, then, after sclerite fixation being stablized with steel plate screw, Kirschner wire is pulled out.When operation process more complicated, Kirschner wire is passed fixing sclerite via the nail of bone-fracture fixation steel plate 5, utilizes the feature that Kirschner wire spheroid 2 is larger than bone-fracture fixation steel plate 5 nail, can bone-fracture fixation steel plate 5 is temporarily fixed on skeleton, be convenient to next step operation technique.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from this utility model principle; can also make some improvement and supplement, these improve and supplement and also should be considered as protection domain of the present utility model.
