Specific embodiment

To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference toSpecific embodiment, the present invention is further explained.

The novel outer fixed bone spicule structure of one kind as described in Figure 1, including metal needle body 1, tail cap 2, l-lactic acid syringe needle 3And l-lactic acid inner core 4, metal needle body 1 are hollow tubular structures, uniformly distributed connection screw thread on the inner surface of front end and end,Uniformly distributed several open-works 5 on the side wall of 1 first half of metal needle body, and 5 axis of open-work and 1 axis vertical distribution of metal needle body, it is leftRotation polylactic acid syringe needle 3 is conical structure, and end face embedded in 1 front end face of metal needle body and passes through connection screw thread and metal needle body thereafter1 connection, 2 front end face of tail cap are connect embedded in 1 rear end face of metal needle body and by connection screw thread with metal needle body 1, metal needle body 1,The bearing cavity 6 of tail cap 2, the common closed structure of l-lactic acid syringe needle 3, l-lactic acid inner core 4 divide in bearing cavity 6It does not offset in 1 inner surface of metal needle body, 2 front end face of tail cap and 3 rear end face of l-lactic acid syringe needle, l-lactic acid inner core is 4Porous structure, and the total volume of hole body is 30%-the 80% of 4 total volume of l-lactic acid inner core in l-lactic acid inner core 4.

In the present embodiment, the tail cap 2 includes metal carrying shell 21 and elastic packing block 22, and it is sky that metal, which carries shell 21,Tubular structures, and metal needle body 1 is coaxial is distributed and is interconnected, elastic packing block 22 in metal carrying shell 21 and with goldBelong to carrying shell 21 to be coaxially distributed, 22 front end face of elastic packing block is at least 1 millimeter lower than metal carrying 21 front end face of shell.

In the present embodiment, elastic sealing ring 7 is set between 2 contact surface of the metal needle body 1 and tail cap.

In the present embodiment, the l-lactic acid syringe needle 3 is an integral structure with l-lactic acid inner core 4.

In the present embodiment, in the open-work 5, between each open-work 5 for being distributed on 1 axis direction of metal needle body,In be located at 1 front end of metal needle body and between two open-works 5 of the last end position of metal needle body 1 spacing be metal needle body 1 haveImitate 1/4-the 2/3 of length.

In the present embodiment, 5 aperture of open-work is 0.1-0.5 millimeter, and 5 spacing of two neighboring open-work are not less than 1 liRice.

In the present embodiment, 2 metals carrying, 21 cross section of shell of the tail cap is times in round, rectangle and regular polygonIt anticipates one kind, and metal carrying 21 outer surface of shell sets anti-skid design 23 and connection screw thread 24, and the connection screw thread 24Right above anti-skid design 23.

The present invention in specific implementation, first to metal needle body, tail cap, l-lactic acid syringe needle and l-lactic acid inner coreAssemble spare.

Connect in use, the present invention is carried shell by the metal of tail cap with outside spicule press-fit equipment, withWhen external spicule indentation sets connection, any one position in end face, anti-skid design and the connection screw thread of shell can be carried by metalIt is attached, to meet the present invention and the different matching used needs of external spicule press-fit equipment, spicule is being inserted into patientIn bone, on the one hand by the structural strength of metal needle body, l-lactic acid syringe needle and l-lactic acid inner core to affected bonePositioned, on the other hand decomposed in bone by l-lactic acid syringe needle and l-lactic acid inner core, realize to it is each byIt damages position to carry out equally improving bone healing resume speed, directly passes through metal needle side after wherein l-lactic acid inner core decomposesOpen-work on wall penetrates into tissue, and in addition to this, on the one hand tail cap is sealed metal needle body, prevents external skyGas, pollutant pollute metal needle body and patient's wound, on the other hand can be as needed, by the drugs such as anti-inflammatory, nutrition headFirst it is added to by the way that injection device is then penetrated tail cap elastic packing block and and metal by syringe needle in external injection deviceDrug etc. is transported to subjects bones' lesions position to realize by needle body connection, is further reached anti-inflammatory, analgesia, is nourished boneThe purpose of, the organized renewings speed such as affected bone and muscle.

When extracting spicule, the present invention is carried into shell by the metal of tail cap and is connect with external spicule extraction equipmentIt realizes and extracts operation, when extracted, since l-lactic acid syringe needle and l-lactic acid inner core are decomposed in patient's body, to haveEffect will reduce the self weight and volume of spicule, the gap between metal needle body and subjects bones, musculature be increased, to improveExtract operating efficiency.

The configuration of the present invention is simple, flexible and convenient to use, versatility is good, on the one hand has good structural strength, can be effectiveSatisfaction to the needs of bone connection positioning operation, while can also effectively according to the needs of use wound be effectively protected andOn the other hand targeted flexible medication can effectively improve spicule and pull out from bone to promote the speed of bone healingEfficiency when out, and extract after wound area it is small, be convenient for quick healing of cut, and can effectively prevent spicule extract operation when pairPatient's wound causes secondary injury.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.Above-described embodiment and explanationIt is merely illustrated the principles of the invention described in book.Without departing from the spirit and scope of the present invention, the present invention also hasVarious changes and modifications.These changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the inventionIt is defined by the appending claims and its equivalent thereof.
