Abstract
The utility model discloses a broken-type threaded location needle, which comprises a first body portion and a second body portion connected with the first body portion. One end of the first body portion connected with the second portion is provided with a hexagonal convex portion in protruded mode, a thread is positioned at the other end of the first body portion, an arc section is arranged between the first body portion and the hexagonal convex portion, one end of the second body portion connected with the hexagonal convex portion is provided with a groove, and a rotary head installation portion is arranged at the other end of the second body portion. The broken-type threaded location needle is convenient to install and capable of fixing crushed bones around skeleton.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of formula screw thread positioning needle that fractures.
Background technology
Fracture many times all is smashing, leans on steel plate or intramedullary pin merely, and possible fracture fragments is difficult to reset to satisfaction; Therefore, in the prior art, people can adopt the steel wire bundle technology usually in order to solve this technical problem; Promptly tie up fragment tightly with steel wire; Yet because fracture fragments all is irregular, medullary cavity is round; Therefore steel wire bundle is very limited to the help that resets, and postoperative should cause the loosening and steel wire of steel wire to be stuck in the disconnected section of fracture place to make it produce the bone does not connect consequence.
Therefore, be necessary to provide a kind of formula that fractures screw thread positioning needle that solves the problems of the technologies described above.
The utility model content
This utility model technical problem to be solved is: but a kind of fix bone easy for installation formula that fractures screw thread positioning needle of broken bone on every side is provided.
For solving the problems of the technologies described above; The technical scheme that this utility model adopts is: a kind of formula screw thread positioning needle that fractures; It comprises: first body and second body that is connected with first body; The end that said first body is connected with second body convexes with the hexagonal protuberance, and the other end of said first body is provided with screw thread, is provided with arc section between said first body and the hexagonal protuberance; The end that said second body is connected with the hexagonal protuberance is provided with groove, and the other end of said second body is provided with the rotary head installation portion.
The beneficial effect of this utility model is: this positioning needle is passed blade plate and change in the skeleton through rotary head; Second body then fractures; Continue to be screwed into first body in the skeleton through box spanner again; Thereby can fixedly secure the broken bone around the skeleton, and the installation of this kind positioning needle is comparatively convenient.

Fig. 2 is the cutaway view along A-A line shown in Figure 1.
Fig. 3 is the cutaway view along B-B line shown in Figure 1.
Among Fig. 1 to Fig. 3: 1, first body, 2, second body, 3, the hexagonal protuberance, 4, screw thread, 5, arc section, 6, groove, 7, the rotary head installation portion.
The specific embodiment
See also Fig. 1 to Fig. 3; A kind of formula screw thread positioning needle that fractures; It comprises: first body 1 and second body 2 that is connected with first body 1; Said first body 1 convexes with hexagonal protuberance 3 with the end that second body 2 is connected, and the other end of said first body 1 is provided with screw thread 4, is provided with arc section 5 between said first body 1 and the hexagonal protuberance 3; The end that said second body 2 is connected with hexagonal protuberance 3 is provided with groove 6, and the other end of said second body 2 is provided with rotary head installation portion 7.The tip of said screw thread is provided with several cutting blades, thus convenient the screw-in in the skeleton, and the length of said first body is 25-50mm.The said formula screw thread positioning needle that fractures is processed by rustless steel or titanium alloy.
During use; At first rotary head is installed on the rotary head installation portion 7 of second body 2; Start rotary head then and this formula screw thread positioning needle that fractures is passed blade plate and change in the skeleton, second body 2 that then fractures is enclosed within on the hexagonal protuberance 3 through box spanner and continues to be screwed into first body 1 in the skeleton; Thereby can fixedly secure the broken bone around the skeleton, and the installation of this kind positioning needle is comparatively convenient.Being arranged so that of said arc section 5 fracture between the locating hole of formula screw thread positioning needle and blade plate cooperate tightr.The formula that fractures screw thread positioning needle in this utility model can make steel plate in the scope of pre-fixing, be fitted in before fixation steel plate to make it motionless on the skeleton, thus make things convenient for screw insert with art in the resetting of bone.
Claims (4)
